Retiring as a Debian developer

This is a repost and update of my retirement letter sent privately to Debian last month, July 10, 2016. At that time I received many notes of appreciation and good wishes which I treasure. Now, I’d like to say goodbye to the broader Debian community and, as well, indicate which of the cleanup items have since been addressed in strikethrough style and with annotations. Also, I’d like to stay in touch with many of you, so I have added some comments oriented towards those of you who are interested in doing that after the letter.

When in 1995, on a tip from a friend, I installed Debian on my 386 at work and was enthralled with the results, I could not have foreseen that two years later, friends I had made on channel #debian would nudge me to become a Debian developer. Nor when that happened did I have any idea that twenty years later, I’d consider Debian to be like family, the greatest free software community in the world, and would still be promoting it and helping people with it whenever I could. Debian quietly, unexpectedly became a part of what defines me.

My priorities in life have changed over that time, though. I have shifted my attention to things that are more important to me in life, such as my family, my health and well-being physically and spiritually, and bringing all I can to bear on the task of preserving our local wilderness areas and trails. In the latter area, I’m now bringing all of what Debian has helped shaped me to be to the table, launching some ambitious projects I hope will bear fruit in the coming years, and make a measurable contribution to help us hang onto our precious natural preserves where I live.

Unfortunately, as I’ve poured more time and energy into these things, I’ve increasingly not been giving my packages the care they need. Nor do I have any roles or goals now for any of the Debian projects I was previously involved in. So, after much careful deliberation, and as much as it pains me to say it, it’s time to retire as a Debian developer. It has been a great privilege to work with you, and to meet many of you in New York at Debconf 10. I plan to be around online, and will continue to take an interest in Debian, lending a hand when I can. Thanks for all of the fun times, for all that I’ve learned, and for the privilege to make awesome things with you. I’ll treasure this forever.

So much for the soppy bits. 🙂 Now, business. These things remain to clean up upon my departure, and I’d appreciate help from QA, and anyone else who can lend a hand. My packages are effectively orphaned, but I haven’t the time to do any of the cleanup myself, so please speak up if you can help.

  1. Debian Jr.
    • O: junior-doc. The junior-doc package has been awaiting an overhaul by whoever revives the project since I gave it up years ago. I’m still listed as maintainer and that should be changed to Debian Junior Maintainers <> if they want it. Otherwise, it is orphaned.
    • I should also be dropped from Uploaders from debian-junior, the metapackages source. Fixed in git.
  2. Tux Paint. This is a very special package that deserves to go to someone who will love it and care for it well. There are three source packages in all:
    • O: tuxpaint
    • O: tuxpaint-config
    • O: tuxpaint-stamps
  3. O: xletters. This is a cute little typing practice game and needs a new maintainer.
  4. XPilot is co-maintained by Phil Brooke <>, so he should replace me as Maintainer. Phil said he’ll pick up xpilot-ng and will also look at xpilot-extra.
    • xpilot-ng
    • O: xpilot-extra (recently removed from testing due to my neglect, and not co-maintained by Phil; it’s unclear if anyone really uses this anymore)
  5. GTypist is co-maintained by Daniel Leidert <> and should replace me as Maintainer.
  6. My ruby packages. A group of packages that I brought into Debian as dependencies of taskwarrior-web, which I never completed. Maybe they’ll be useful in and of themselves, and maybe not. In any case, they are maintained by pkg-ruby-extras-maintainers, but I’m the sole developer in Uploaders and should be removed: Fixed in git.
    • ruby-blockenspiel
    • ruby-parseconfig
    • ruby-rack-flash3
    • ruby-simple-navigation
    • ruby-sinatra-simple-navigation
    • ruby-term-ansicolor
    • ruby-versionomy
  7. Debian Live stuff: I am listed in Uploaders for live-manual (fixed in git) and debian-installer-launcher (fixed in git) and need to be removed.
  8. O: eeepc-acpi-scripts. The defunct Debian EeePC project has just this one package. Recently, the mailing list was asked about its status, and it was recently NMU’d. To my knowledge, nobody from the original team remains to take care of it, so it needs a new maintainer. I should be removed from Uploaders, and since the Debian Eee PC Team no longer exists, it should be removed as maintainer. It is effectively orphaned unless someone speaks up.

There are also some Alioth projects / lists that are defunct that I’ll need to talk to the Alioth admins about cleaning up in the coming days. One of these is <> and since it is still listed as the maintainer of eeepc-acpi-scripts, that needs to be sorted out before the list can be closed.

Thanks again, and see you around!

Stay in touch

For those of you who would like to stay in touch, here are some ways to do that:

  • Follow my blog:
    If you already do that, great! If not, welcome to my blog! For the past couple of years you may have noticed a decrease in technical content and increase in local trails and conservation oriented posts. You can expect more of the latter.
  • Say hi to me on irc: SynrG (also SynrGy) on ( or
    I still intend to hang out and offer support when I can, just no longer as a developer. Channel #debian-offtopic on either network is a good place to catch up with me socially.
  • Follow me on Facebook:
    For better or worse, a lot of the trails and conservation folks hang out here, and many of you in the Debian community are already my Facebook friends.
  • Look for my Bluff Trail posts on their site:
    Providing tech support to this organization is where much of my time and energy is going these days. I post here once in a while, but do most of my work behind the scenes as a volunteer and, newly this year, as a board member.

Wifi roaming on the move redux

It has been nearly six years with a netbook and five since I last wrote about wifi roaming from the bus to stay on irc without a costly celluar link during the daily commute.  Since then, some readers have asked me to share my refinements to the method in a followup post. So here it is.

The software

On the server:

  • openssh-server
  • screen
  • irssi

On the client:

  • screen
  • wpasupplicant
  • isc-dhcp-client
  • openssh-client
  • openbox
  • sudo & gksudo (optional)
  • urxvt
  • wavemon (optional)
  • three shell scripts (provided below)

Putting it together: on the client

Make sure if you have a wireless manager installed (such as NetworkManager) it is configured to skip your wireless interface, disabled entirely, or if possible, removed. Set up /etc/wpa_supplicant/wpa_supplicant.conf and /etc/network/interfaces for roaming, as per the instructions in /usr/share/doc/wpasupplicant/README.modes.gz. Don’t forget to add yourself to the netdev group if you are not in it already.

In /etc/wpa_supplicant/wpa_supplicant.conf, list common names of open networks. Normally the catch-all network that associates with any essid, i.e. the first stanza below, works well. However, occasionally the strongest signal is neither one of the common networks nor an easily accessible network (e.g. web portals), so having a list of common open networks helps to quickly select from among those instead. The more you travel, the more of these will discover and add. Just use reconfigure from wpa_cli to reload your edited list each time you add a new one.

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

Since you’ll be using ssh repeatedly to connect and it has to be fast, make sure your server is set up to accept your key and use ssh-add so that you only have to enter your ssh key password once.

You can tweak isc-dhcp-client to make connections faster. In /etc/dhcp/dhclient.conf, use:

backoff-cutoff 1;
initial-interval 1;

Here are a few scripts I wrote to facilitate quick roaming from one open AP to another and reconnect to irssi running in screen, to break a connection and try the next one, and to recover from occasional lockups (more about that later).


This is a script to reconnect continuously via ssh to a screen session:

while ! ssh -t 'screen -UDr' 2>/dev/null ; do echo -n "." ; sleep .1 ; done

Just substitute the IP of your own server here. Using an IP instead of domain name makes the connection faster because a DNS lookup is not required.


This script closes any open ssh sessions and informs wpa_supplicant to attempt to connect again.

/sbin/wpa_cli rea
killall ssh >/dev/null 2>&1


This optional, somewhat ugly script addresses an issue I hope you never have. On my ASUS Eee PC 1001PX, occasionally scanning stops. When this happens, and I have never figured out why, apparently ACPI events are blocked. At this point wifi becomes unusable and ACPI sleep is inhibited. By trial and error I found that if you bring down the interface, kill all network-related processes, and bring it up again, ACPI events are unblocked and wifi is usable once more (and any pending request to sleep will finally happen). The script requires sudo, and to use the openbox key binding, gksudo.

sudo ifdown wlan0
# in case any of these are hung
sudo killall dhclient3
sudo killall wpa_cli
sudo killall wpa_action
sudo killall wpa_supplicant
# in case any of these are *really* hung
sleep 1
sudo killall -9 dhclient3
sudo killall -9 wpa_cli
sudo killall -9 wpa_action
sudo killall -9 wpa_supplicant
sudo dhclient -r
sudo ifup wlan0


Since certain actions need to be performed repeatedly and quickly, it is useful to have hotkeys bound in your window manager to the scripts. In ~/.config/openbox/rc.xml, key bindings for <alt>-r to reassociate and <alt>-d to disconnect a hung connection would look like:

  <!-- My keybindings -->
  <keybind key="A-R">
    <action name="Execute">
  <keybind key="A-D">
    <action name="Execute">
        <execute>gksudo /home/synrg/bin/wifi_killall</execute>

Putting it together: on the server

There is very little to do here. Just start screen, and start irssi in screen. Running screen on the client as well as the server means you should either bind the screen meta keys to a different key sequence on each system, or else learn to press meta twice to pass through meta to the server screen as needed. I use the latter approach. Alternatively, you could use a tabbed terminal on the client, or separate terminals per client process instead of screen. This is a matter of personal taste.

Ready to roam

Here is a typical setup for roaming on the bus:

In a terminal (I use urxvt), first ssh-add, then start screen with these three processes running in separate virtual terminals:

  • /sbin/wpa_cli
  • screen_reconnect
  • wavemon (optional)

March of the dots

Most of the commute, just enjoy watching the dots march by, waiting for a new connection. If you estimate a connection is unusable, press <alt>-r to reassociate immediately, giving the next network a chance. If the connection is already firmly established, this might not work on the first try. If the dots don’t resume immediately, wait a bit and press it again. This might take a few tries.

Changing selected networks on the fly

Use wpa_cli when you need to do some fine-tuning of network selections on the fly. While normally you can just watch the march of the dots until a connection is acquired, sometimes you can improve your chances of connecting to a good network by manually controlling the selected candidate networks here.

For example, by watching the speed of the bus relative to known “good” APs, you can predict which networks are more likely to succeed. Rather than connect to any arbitrary network, you might select a specific one by id, and then later when it goes out of range, revert to the original configuration, e.g.

> select_network 5
> reconfigure

You can use tab-completion in wpa_cli to type these commands quickly or else just abbreviate the commands.

Another common scenario is when you pass through a business area with many captive portal hotspots. These rarely make good choices because they either require a password not known to you or else you can’t click through “I agree” in time before the bus moves on. In this case, you might just disable the catch-all stanza and let the common open network stanzas you listed (“default”, “linksys”, etc.) do the work:

> disable_network 1

Become a type ahead wizard

While running, a continuous stream of periods fills the screen, which provides you with a highly visible cue that no available APs are in range. When the movement stops, you know a connection is being attempted.

While waiting to connect, you can type ahead any comments you want to make in the current irssi window (taking care to remember which one you are in!) While having periods interspersed in what you type may be disorienting at first, you get used to it.

There is a point when a connection is first established and ssh is accepting input, but anything you type can no longer be seen while you’re typing. Depending on whether the connection was completely successful or not, what you type now may or may not finally be sent. For best results, only type ahead before the dots stop moving.

Eventually you can become skilled enough at this to type ahead a comment in one channel, switch channels with /win # and continue typing ahead in the new channel, all buffered until the next few seconds (or even fraction of a second) of connection time.

Fine-tune antenna direction with wavemon

When the bus has come to a standstill, you may find wavemon useful to pull in a weak signal. Because wavemon has continuously updated signal level and link quality bars, you can use it to fine-tune the antenna position. Just turn your laptop until the bars are at their maximum.

Captive portals

I have not figured out how to do any automation for this, so it really is a crapshoot, as it is likely the bus has moved on by the time you’ve managed to manually navigate the login through a captive portal. But in rush hour, you may have the luxury of time to connect to these as you pass them. I have recently learned about the CoovaFX Firefox plugin which automates logins to captive portals. I’m going to give it a try to see if it helps. Update: I can’t recommend this plugin, as it is not compatible with Iceweasel >= 23.0. Also, the standard it is based on, WISPr, appears to have an uncertain future. That, coupled with the fact that the plugin appears to not be open source means I’m still looking for alternatives.


If all of this sounds a bit nuts to you, well, it probably is. But after half a decade enjoying free access to irc from the bus, it all seems perfectly natural to me! If you try this method and like it, please let me know in the comments. Likewise, if you have any improvements to the process or scripts, please share them!


Eee PC care at 2 years

In November 2007, we bought two of the first Eee PC netbooks available in North America: the model 4G in pearl white, one for me, and one for my wife. My plan was to start the Debian Eee PC project and get Debian working on them both which, thanks to the work of everyone on the team, has been a great success. Fast forward to February 2010, and they are still serving us well. Here is a list of hardware enhancements and issues over the past two years of continuous use:

Battery life

Asus claims 3.5hrs for the model 4G, though I don’t think we ever experienced anything better than 2.5 hrs with wifi in operation. Today, I’m down to something short of 2 hrs. If you consider the Lithium ion battery article on Wikipedia to be accurate, it is typical to permanently lose 20% capacity per year, so this sounds about right for the age of the battery.


The touchpad itself is fine. The buttons are not. They are hard to push and prone to become less responsive after a while, or to fail entirely. I now really have to bear down hard on my left button to make it work. Because the buttons are soldered to the motherboard, they would be hard to replace. Configuring the synaptics driver for tap-to-click is an acceptable workaround. Also, one of the first purchases we made was the Logitech VX Nano, one for each Eee, so most of the time now, we use our mice, falling back to the touchpad only when using a mouse is inconvenient due to space constraints (e.g. on the bus).


After two years of continuous use, both of our keyboards needed replacing. Some of the keys had been pounded flat and needed surgery (rubber springs sliced out of a scavenged Acer netbook keyboard and grafted on) to make them usable again. And aesthetically, the keyboards have really suffered, with a good percentage of the markings on the keycaps partially or completely eroded off.

Fortunately, for $3 plus $10 shipping each, new keyboards can be ordered from a Chinese e-Bay seller. But with the new keyboards, there is still the problem with excessive flex in the keyboard making some keys less responsive than others. I’m considering trying this hack to solve the problem.


I have no complaints about the matte finish displays of either Eee. Both have stood up well. People tell me they don’t care for a 7″ display, but I find it bright, crisp and easy to get along with, so long as you maximize windows and increase font size as needed (e.g. for reading PDF books and magazines). When I really need the extra real estate, I just hook up an external monitor.


Some people complain about the noise of the fan, from the otherwise silent 4G (due to the lack of a hard drive) and seek ways to limit the amount of time the fan runs. We’ve never had that problem. However, if any plastic bits break off inside the Eee, they will eventually find their way to your fan and get wedged. This has happened twice: once in my wife’s Eee, and once in mine. Disassembly of the Eee to clear the blockage and get the fan running again was relatively painless both times.

Plastic bits

About those plastic bits: In my wife’s case, I think the bit was some extruded plastic from the molding that had broken off. In my case, it was a deteriorating plastic post which was holding the hinge in place. More about this later.


Unfortunately, the integrated sound seems to be particularly sensitive to heat. During both fan failures, sound cut out. On my wife’s system, it never fully recovered, and now only works on alternate Tuesdays, whereas on mine, after I unwedged the fan and brought the heat down, sound has functioned properly ever since. (Update: see my comments below on power adapters for an alternate theory about what killed sound.) We are waiting now for the delivery of a cheap ($1.42 including shipping, again from China) 3D Sound USB device which is reported to work on Linux. While some users complain about hum with this device, we’re cautiously optimistic that on the Eee it won’t be an issue. If it is, oh well, a buck and a half is a small gamble.

Update: It works! My wife is very happy. Money well spent.

Display hinge

The plastic posts that hold the anchors for the machine screws for the hinge are fragile. Three out of four of these posts in my Eee have shattered, leaving the left hinge to float freely. For the past two days I was distressed about how I could fix this. Based on some helpful suggestions from #eeepc @, I had worked out a plan to rebuild one of the posts with two-part epoxy, sand it and the fractured stub of the post, and use cyanoacrylate glue to affix it to the case. It sounded like fiddly work for which I didn’t hold much hope of success. But this morning, I realized that the plastic in the bottom of the case was still sound, and that I could drop a screw into that hole, and with pliers, line up the anchor on the other side. This appears to work! I’ll handle that hinge with care, but it should do me until I eventually repurpose the machine to some daily use that is less stressful on the hinge than daily travel on the bus.

Update: Sadly, this broke on the weekend. The thin bit of plastic at the bottom of the hole just couldn’t take the stress. I’m planning a second attempt to fix it soon, using sturdier materials.


Some people were initially worried that the limited write life an SSD meant that you needed to take special measures to avoid its premature death, which I have always regarded as a myth. Our 4G SSDs each have no swap space, and ext3 filesystems. At the two year point, there are no problems. I expect our SSDs to outlast the other components.

We did, however, eventually find the 4G to be a bit on the small side. We now each have Kingston 4G micro-SDHC cards for a bit of extra capacity for large media files and for some extra space for the apt cache. I recently priced the Lexan version of this card at $19 for a two-pack at Wal-mart, and these seem to work in the model 4G just as well (which seems to be an issue with this model — not all SDHC cards work).


We found the 512M that came with the 4G somewhat constraining. Without any swap space (so we could maximize the space available on the small SSD) we decided our systems really needed a memory upgrade. At the time, 2G didn’t seem overly expensive (though I no longer remember the exact price) so we splurged on 2G for each system, even though that was probably more than we needed.

Power adapter

When I first wrote this article, I forgot to mention the power adapter. The model 4G uses an unusual 9.5V power adapter for which it is hard to find a generic replacement. This unit is prone to fail in two places: in rare cases, (one out of 6 units that I have in some way assisted with: 3 of them mine, 3 belonging to others,) it will break at the wall plug end. The plug swivels into the unit for easy storage, but this adds a point of failure. More commonly, (in 3 out of six of the units,) the wires at the netbook plug end will fray due to stress on the non-angled cord, leading either to no connect, or to a short. In fact, since in the case of my wife’s adapter, the netbook end of the cable shorted, making the cable heat up and the system spontaneously shut down after a little while, we can’t say for sure whether the overheating of the Eee took out integrated sound, or whether this short did. On the one hand, I know for certain my own system, which never suffered a short, has responded to overheating by making the sound flaky, but it has never taken out sound completely. On the other hand, shorting the power cable can’t be very good for the Eee, so who knows, maybe that’s what ultimately killed my wife’s Eee’s sound.

This is where it helps to have soldering skills, or a friend who can do the repair for you. In my case, it was the latter. While I was waiting for a replacement adapter I had ordered, we also found on part#s for replacement plugs and sleeves from Digikey, total cost $20 including shipping, 10 pieces each. Cutting off the bad plugs on three units and attaching the new was a quick, straightforward operation, and succeeded in two out of three cases. Having carefully checked the failed repair, we deduced that the failure in that unit was at the wall end, and we judged there was nothing further we could do to try to save it. Even the unit that had previously shorted was returned to perfect health and has been in operation trouble-free ever since.


After over two years of continuous use, the model 4G has held up well for a $400 system. We definitely feel we have received our money’s worth of value over that time. All of the problems we’ve experienced so far have been fixable at very little expense, and we expect them to last at least another year before we seriously consider replacing them. In the next several months, I plan to order a high capacity 8-cell 10400mAh battery for my own system so that I can enjoy a 5-6 hr run time. The purchase will be roughly $55 including shipping, the most expensive purchase for my system to date, but still well worth it to extend the 4G’s lifespan for another year or more.


Bits from the Eee PC team, Spring 2009

Lenny well supported

We’re pleased that Lenny released with good support for the Eee PC and are now turning our efforts to make Squeeze even better, while continuing to provide support for our Lenny user base.  The standard Lenny installer can install Debian on all models of Eee and our custom installer provides the ability to install over wireless for almost every model (more about this later) from a very small image.  The latter continues to be our recommended install method, since in addition to being wireless-ready, the custom installer also handles a few other small eee-specific configuration chores to make as much as possible “just work” right after the install.

Solid mainstream support

We’ve made good on our promise to make Debian work on the Eee PC, not a derivative, many of which use a custom kernel instead of the stock kernel as we do and use a special desktop instead of our users’ favourites.  While we agree that some intriguing things can be done in these areas, it is no substitute for mainstream support.  Our users are better served by a solid foundation than specialised modifications that limit their choices.  We want them to be able to enjoy the freedom to mold Debian, the universal OS, into whatever suits them best.

Squeeze support started

Work is well underway on supporting all Eee models in Squeeze.  For months, several team members have been experimenting with new kernels, producing support for them in eeepc-acpi-scripts.  The current release of this key package (version 1.1.0) supports Linux 2.6.29 and contains enhancements for wifi, sound hotkeys, bluetooth, external displays and OSD.

Squeeze will support wired & wifi on all current models

With the appearance of 2.6.29 in Sid, all ethernet and wifi cards used in all models of Eee today are supportable without the need for out-of-kernel or non-free drivers.  Madwifi is replaced by the free ath5k driver, the non-free rt2860 package is replaced by mainstream kernel support, (though it still requires non-free firmware provided separately by firmware-linux — for now in 2.6.29, the firmware is included in the kernel, but that is a bug fixed in 2.6.30,) rtl8187se is included, making it possible now for us to support the model 701SD, and ath9k is included, making full support for newer models such as the 1000HE possible.

Lenny backports and live demo

All of these changes can be enjoyed today by Lenny users.  Just add Daniel Baumann’s Lenny kernel backport repository and then install the 2.6.29 kernel and an updated acpid.  See our upgrade howto for details.  You can try a small (less than 256M) demo of this configuration by downloading beta 2 of our Live USB image.


Late last year, we discussed how to make it easier for the blind to install Debian unassisted on their Eee PCs.  As it was a simple change, we now include brltty in the custom installer, but we understand that some users also need software synthesized text-to-speech, something for which there is no support yet in the standard Debian-installer.  We understand this isn’t an easy thing to fix, but hope someone will rise to the challenge.

Growing team of developers

We welcome Darren Salt and Raphael Geissert to the team this year.  Both have been actively making contributions to the eeepc-acpi-scripts package over the past months, fixing some outstanding bugs and readying it to handle changes in more recent kernel releases.

Moved to new hosting

Nico Golde, who hosted for the first year development, has turned his focus to other areas of Debian.  Glenn Saberton has stepped in to provide a new home for it.  We thank them both for their efforts and for a smooth, uneventful transition from one host to the other.

Size of user community

Speaking of the move, earlier this year, Glenn shared with us some interesting archive traffic statistics that give us a rough idea how many users we have.  For the months of December and January, after factoring out bot hits, we were seeing about 300,000 hits from 15,000 unique users per month.  The site handles roughly 60G of traffic per month, most of that from thousands of downloads of our custom installer image.  It’s hard to draw any firm conclusions about the size of our user base from these stats, as many users may be on dynamic IP numbers, inflating the numbers, but we can conservatively say we have at least 5000 users.  Other interesting statistics are that we have anywhere up to 80 users at any given time on our irc channel and over 250 users on the mailing list.

Help wanted

The Asus Eee PC line continues to expand, with 24 models listed so far.  It is a challenge to keep up support for all of them.  We’re encouraged to see Asus choose a new b/g/n wifi chipset for their 1002HA that is supported by a DFSG free driver — ath9k in this case.  It appears that the new Atom N280-based 1000HE uses the same chipset as well (though be careful: I know of at least one user who bought a 1000HE in Argentina expecting it to have this chipset and was disappointed to find it had the Ralink chipset instead, we guess because of availability).  If this trend continues, we’ll be that much closer to our goal of full support for Squeeze main.  As it stands, we’re already as close as we can get given the state of rt2860 and no prospect on the horizon for replacing the non-free firmware.

If you would like to help us out in any way, whether by testing, debugging, patching, or improving our documentation, get in touch with our team.  We rely on your feedback to keep Lenny in good shape and work towards making Squeeze even better for all users of Debian on the Eee PC.


Wifi roaming on the move

Preface: legal stuff

Depending on where you live, use of random open wifi networks might be considered illegal. Although I know of no law in my country against doing this, where you live, things may be different, so educate yourself before following my example.

Wifi roaming on the move

For the past year I have used my Eee PC on the metro transit bus, as it is the perfect size for this. When I can, I take advantage of open networks to connect back home. In this article I will show how you can actually use such access, will recommend which software works best and will explain how to set it up.

So, what can I really do with the net while in motion?

How about irc? No kidding! This shell one-liner does the job:

while ! ssh -t 'screen -UDr' 2>/dev/null ; do echo -n "." ; sleep .1 ; done

We’re concerned about privacy and security on other people’s networks, so we use ssh. Inside that screen session, keep irssi running for a continuous irc presence. Every 10th of a second, the script tries to resume your session. Once a the net passes by, typing “[Enter]~.” drops you back out to retry again. The row of dots serves as a progress bar. If you want to get fancy, you could replace that with an ASCII ‘spinner’. I leave that as an exercise for the reader. 🙂

Come on, is that really usable?

Certainly. As the good folks on #eeepc at and #debian-eeepc at can attest, even a half dozen brief connections can be enough to provide tech support, rough out some development ideas, or just carry on some friendly chat. If your spouse or housemate is online too, it can even help you make some last-minute grocery-list changes. 🙂 While the script is working, enjoy some offline things such as blogging, reading a cached Planet Debian feed or a PDF book.

OK, so what else do I need to make it work?

Well, you’ve seen so far we need on a server:

  • openssh-server
  • screen
  • irssi

On the Eee, you should also have:

  • openssh-client
  • wpasupplicant
  • gnome-terminal

But what do I need wpasupplicant for if I only use open networks?

Well, wpasupplicant is really handy for fast control of networks in Roaming Mode (as per /usr/share/doc/wpasupplicant/README.modes.gz). A GUI is just too slow. For example, you may need to filter out ‘junk’ open wifi nets: pay-per-use hotspots or nets that hide their name. You’ll not only want a “catch-all” stanza for any open network, but also a number of the most commonly found default network names, e.g.

# Catch-all; associates with any open network:
# Commonly found default network names:
# etc. by watching scan_results closely you'll find several more

While the connect script is running, keep a separate tab open in gnome-terminal for wpa_cli. Use ‘disable_network 0’ to drop the catch-all and let the other stanzas kick in and ‘enable_network 0’ after filtering is no longer needed.

Isn’t it really slow to get connected?

Without some tweaks, yes. But here are a few things I have found by trial and error that help.

One issue is that dhclient takes too long to retry, so you drop the delay between retries back to 1 second in /etc/dhcp3/dhclient.conf:

backoff-cutoff 1;
initial-interval 1;

If the signal is very weak, you’ll want the transmit power turned up to the maximum value for your hardware. For the Eee PC 4G this is 50mW, so you set this in /etc/network/interfaces for ath0, your wireless interface:

wireless-txpower 50mW

Finally, while you’re in motion you are constantly leaving no-longer-usable access points behind. The driver needs to discard them as quickly as possible and scan for new ones. So again in /etc/network/interfaces for ath0, you bring the default scanvalid 60 seconds down to 10 with:

pre-up /sbin/iwpriv ath0 scanvalid 10


The netbook has changed how we use the net. Now that we can take it everywhere, we either pay through the nose for expensive cell network access or else use the patchy wifi coverage blanketing most urban areas. A few lucky cities have such things as municipal wifi nets, but the rest of us have to scrape what access we can wherever we go. You are now equipped to try this out on the bus. If you find any other tips that can help, I’d love to hear from you.


Bits from the Debian Eee PC team, autumn 2008

Some brief highlights of the last three months of Debian Eee PC development.

Thermal and ACPI breakage resolved in 2.6.26-7

We’re pleased to see that in the upload to Sid of linux-image-2.6.26-1-686 version 2.6.26-7, the pair of 2.6.26 bugs we’ve been tracking that have made it difficult for Eee users to upgrade their systems have been resolved. Since then 2.6.26-8 has been uploaded and is expected to enter Lenny this week due to a freeze exception. Once the new kernel has migrated we will move quickly to build and release a new installer that includes it.

Ath5k wifi works on Eee PC in Linux 2.6.27

Jean-Christophe reports that ath5k works in Linux 2.6.27 on the Eee PC 701, and just needs a small patch to work with our eeepc-acpi-scripts package. This is good news for those of us with models 701, 900, 900A and 1000HD who have been wanting to get off of the non-free Madwifi drivers and onto DFSG free drivers.

New Eee PC model 701SD wifi support in the works

Users of the new Eee PC Model 701SD have just started showing up looking for support in mainstream Linux distros. Martin Filtenborg confirmed using our Eee PC Live image with the GPL’d rtl8187se driver from Realtek that we can at least use it to connect to an unencrypted AP, get an IP address and ping other hosts.

Of course, it is one thing to have a working vendor-supplied driver and quite another to have mainstream support. We’ll make do with what we have now, but will be seeking a mainstream solution as soon as possible.

We’re seeking more testers and developers to work on this. To date, an ITP has not been filed, as it is not yet clear who is going to carry this work forward.

Chasing the 5 second boot

An interesting discussion on Arjan van de Ven and
Auke Kok’s work to get an Eee 901 to boot in 5 seconds
took place this month. While the Debian Eee PC team is not making work on this a priority, we’ll keep an eye on it to see if Debian can incorporate some or all of the techniques they used so that our users can benefit without making radical changes to their systems.

Working towards mainstream support for rt2860

Our filing of an ITP for rt2860 (the wifi driver for models 901, 1000 and 1000H) was followed by discussion about how to separate out the GPL’d driver from the embedded non-free firmware so that it can at least go into contrib. Glenn Saberton has been working on rewriting the build system around kbuild and separating out the firmware.

Numerous improvements to ACPI scripts

Since my last progress report, there have been numerous improvements to the eeepc-acpi-scripts package to deal with all of the various models we now support and make the scripts more robust and flexible. Check out the changelog for details.


Bits from the Debian Eee PC team, summer 2008

As always, we’re doing lots of interesting and significant things and have more good ideas than we have people to do the work.  If you have an Eee PC or are planning to get one, or are otherwise interested in our work, some of which has uses beyond just the Eee, here are some highlights:

Earliest Eee models supported in Lenny

Lenny will release with the atl2 ethernet driver and the non-free madwifi-source now works with the earliest Eee models as well, so our patched version is no longer needed.  This means Lenny will work with all of the earliest models of the Eee PC: 701 (2G and 4G surf, 4G, 8G) and 900! All we need now for full support in Lenny is to replace the non-free wireless driver with the free ath5k driver when it is ready.

Free drivers

Nick Kossifidis has submitted patches on linux-wireless supporting the Eee models currently supported only by the non-free madwifi in ath5k.  This means we’ll soon realize our goal of a completely DFSG free system for the earliest models of the Eee.  By 2.6.27, or at the latest 2.6.28, these models will be supported.  Then we will see about making a patch to support whichever kernel makes it into Lenny.

New models

Model 901, 1000 and 1000H users are now able to install using the atl1e ethernet driver from  Support for wireless and other aspects of the new hardware will follow soon.  The debian-kernel team was prompt to add atl1e to 2.6.26 which has just been uploaded to sid.  We hope 2.6.26 makes it into Lenny.

Wireless installer

Glenn Saberton has been doing an upstanding job adding wireless support to our custom Debian-installer.  We have supported WEP authentication for several releases, now, and a beta version supports WPA.  Glenn is also making progress with these patches upstream so that non-Eee Debian users will benefit from our work.

LXDE is in Lenny

LXDE has entered Lenny, thanks to Andrew Lee.  It is a quite lightweight desktop environment that is made with the Eee PC in mind.

Live images

Two flavours of Debian-live USB images are available: a demo of the LXDE desktop and a minimal console-only image for rescue/backup.  The images are still in alpha stage of development.  If you’d like to help, give us a shout.

More interesting things are planned for the future that benefit Debian as a whole.  With a small amount of work patching live-helper, anyone will be able to make a live image that includes a customized Debian-installer.

Mobile device initiative

This month on debian-devel, there was some interesting discussion about Debian support for the Intel Atom processor and a possible mobile net device initiative.  That’s something we could get behind, if anything comes of it.

Wiki translation

Robert Epprecht has been keeping the German wiki translation in good shape, but we could always use some more help with any of the translations.

Sister project in Ubuntu to Debian Eee PC

I was pleased to learn through Christer Edwards
of the existence of a sister project in Ubuntu to our Debian Eee PC project. I followed up on his invitation to drop in on their irc channel and introduce myself. I’ve been looking over the bugs listed on their TODO to see if any are applicable to Debian. Already I have filed #479217 based on the corresponding bug in Ubuntu, and have encouraged them to check out ours as well. I look forward to sharing more with them in the future so we can benefit from each other’s work.


Install Debian on your Eee PC over wireless

Installing Debian on your Eee PC is even easier now, as the option to install over wireless is now present in our custom debian-installer image. Also, the new installer automates installation of many more things than prior releases, so wireless, acpi hotkeys and suspend all ‘just work’ out of the box.

Two barriers remain to including wireless support for the Eee in Debian main. The first is the lack of wireless support in the official d-i installer. The second is the dependency on the non-free madwifi driver. I have no illusions about this being ready for Lenny, but I hope in Lenny + 1 this will be realized.

The good news is that Nick Kossifidis is working on getting support for the Eee into ath5k. For patches, see:

I have created a stub page FreeYourEee in our wiki about making a completely DFSG free install of Debian on the Eee. I encourage anyone going this route to contribute.
