SuSE sucks! //at 05:44 //by abe

Since SuSE closes the security support two years after release and the recent KDE JavaShit remote code execution hole wasn’t patched as fast as I would have expected it (the patch came out after the upgrade I’m writing about here) in the SuSE 9.0 which was installed on my 2.66 GHz AMD desktop at work (it started as in 2002 as a SuSE 7.3 on a 400 MHz box and has been upgraded since then to 8.0, 8.2 and 9.0 IIRC), I decided, it’s now really time to upgrade to SuSE 10.0. (Although 10.1 will be out soon, I just don’t want to wait for it.) And since my boss only wants SuSE boxes and neither Debian (which I would prefer) nor Gentoo (which a colleague prefers), I couldn’t simply install Sarge on this box although I would have chosen that option if it would have been available.

Since my former SuSE experiences told me that this would mean a lot of trouble, I took notes from the beginning, once for the blog and once for my boss to show him, that most trouble doesn’t come from me being a power user used to being allowed to touch any config file (like I am on Debian).

Preparations

So I begin with the preparations: Starting the 400 MHz Debian Woody box on my desktop (whose operating system is more than a year older than SuSE 9.0 and still has security support, yeah!) I usually need to build custom Debian packages for customers. There I could chat in IRC and took notes while trying to upgrade and get the whole thing working again.

When everything was ready, I put the SuSE DVD in — just to notice, that it’s just a CD-ROM. So I put the SuSE 10.0 CD1 in the CD-ROM drive and typed “sudo shutdown -r now” in the shell. The box starts shutting down and tells me:

Please stand by while rebooting the system…

But it didn’t reboot. I waited for several minutes, nothing happend. Well, seems as if the SuSE upgrade already starts as I expect it to end: Horrible.

NSLU2 in a Tux Case //at 18:23 //by abe

It started harmless when Thomas asked on Linux User Group Switzerland mailing list if someone knows a tux-shaped alarm clock. But the topic of that thread quickly moved to two other things in tux shape: the Tux Droid, a device similar to the Nabaztag, but needs a Linux host with USB, and ACME Systems’ Tux-Server, a ETRAX CRIS based Foxboard inside a tux-shaped case.

We found out that Telion, the Swiss importer for Foxboards, also imports ACME Systems’ Tux Case — although the Tux Case is not mentioned on their website. Even better: They had a few old Tux Cases in stock which don’t fit anymore on current Foxboards since the position of the power socket changed. (So only one hole in the case was missing.) And they wanted to get rid of them quite fast: They offered us the Tux Cases for 10 CHF (6€) each instead of 28 CHF each (17€) if we buy all of them. Of course we couldn’t reject this offer and bought all five remaining cases.

Another part of the thread was about performance. Although ETRAX CRIS is used by its inventor AXIS in many of its products (they’re famous for the Linux based web-cams) many were not sure if the board’s performance would be sufficient for their ideas. Another disadvantage of the ETRAX CRIS architecture is that no mainstream Linux distribution supports it.

Another point was the Foxboard’s price (169€, ca. 268 CHF). Bones just mentioned that an NSLU2 costs only about 100 CHF (60€).

Probably on IRC someone (probably Bones, too) wondered if it’s possible to fit a NSLU2 into such a quite inexpensive Tux Case. We took Wikipedia’s picture of the NSLU2 board, compared the size of the USB ports on that picture, compared them with real-life USB ports and found out the size of the board that way. And when I got my Tux-Case I noticed that the NSLU2 board really could fit into the Tux-Case.

Since I’m already building a bigger NAS-like home server, I have no use for another, much slower NAS. But since I more or less gave up the also ARM-based Thecus N4100, another ARM-based machine in my hardware collection wouldn’t be bad.

So it didn’t took long and the idea was born to build the NSLU2 board into a Tux-Case and let the website tux.ethz.ch run on it. (I inherited its administration from Beat and it’s currently just a virtual host on one of our webservers.) Then it would be a server named Tux, serving Tuxes, looking like a Tux and running Tux’ operating system Linux. :-)

I ordered an NSLU2 at Brack for 117.60 CHF (ca. 70€). Played around with the original firmware for a moment, but it’s horrible from a security point of view: You can’t even change the admin password (default: “admin”) if no USB harddisk is attached. And no, a USB stick doesn’t suffice. So I didn’t wait long and tried to install Debian’s “armel” (ARM, Little Endian) port on it. But the NSLU2 refused the “new firmware” with the error message “Upgrade: no enough free space.”. While this is not in the Debian specific NSLU2 FAQ, it is mentioned in the general troubleshooting FAQ. As described in there, first upgrading to the most recent firmware version and then uploading the Debian installer worked fine.

After I had successfully installed Debian Lenny on a pqi 4 GB USB sticked into the NSLU2 and verified that everything is working fine, I opened the NSLU2 case and checked if it really would fit into a Tux Case.

It does, but very, very close. You’ll have to drill some holes and the ethernet socket will stick out Tux’s shoulder, but everything else should fit perfectly after a few mounting parts inside the Tux Case have been removed. As a proof of concept I laid the NSLU2 board on the Tux Case’s back:

Pictures taken with my Nokia E51

So later the LEDs will be in Tux’ one shoulder while the network socket will be in his other shoulder. And the USB stick will be inside his paunch via a USB hub.

Debian and GPRS with the Nokia E51 //at 01:33 //by abe

A while ago I wanted to have internet over GPRS (either EDGE or UMTS) via my Nokia E51 working before I leave for the weekend. But whatever I tried, I always got an ERROR if I sent any AT command. Even ATZ and ATH resulted in errors. So started googling for all components: I found AT commands which are said to work with the Nokia E51, I found AT commands which are said to work with Swisscom GPRS and I found many sites describing how to setup a bluetooth modem.

But since the even those AT commands which should work with both, Swisscom GPRS and Nokia E51 didn’t work at all, I noticed that all the Nokia E51 howtos were using the USB cable. So I tried that, too, and it worked immediately. It looks very strange to me that the set of AT commands is dependend on which way you connect to the phone. :-/

So here’s my working PPP config:

hide-password
noauth
connect "/usr/sbin/chat -e -f /etc/chatscripts/swisscom-gprs"
/dev/ttyACM0
460800
defaultroute
crtscts
user "guest"
usepeerdns
noccp
bsdcomp 0,0
lcp-echo-failure 10000
lcp-echo-interval 1000

So I have now four levels of mobile computing available:

• Nokia E51 with T9 and phone keyboard (for short texts)
• Nokia E51 with Nokia SU-8W bluetooth keyboard (for longer texts and emergencies, see photo on the right)
• ASUS EeePC (7", 630 MHz Celeron, 2GB RAM, 4GB SSD) with Nokia E51 as modem (complete computer, but still small, portable and nearly always with me)
• Lenovo ThinkPad T61 (14" wide screen, 2.2 GHz Core2Duo, 4GB RAM, 160 GB SATA Disk) with Nokia E51 as modem (complete computer with power and disk space)

Should suffice in nearly all situations. ;-)

One month with Debian Lenny on the EeePC //at 19:15 //by abe

I ogled with an ASUS EeePC since it was announced, but didn’t want to order one abroad. So I waited until they became available in Switzerland. Digitec is the official EeePC importer for Switzerland and seeems also to be the moving power for yet to come the Swiss localisation of the EeePC. But initially they only offered imported EeePCs with German keyboard layout, but since I really got used to the US layout, I didn’t want to buy ay new laptops or keyboards with German layout.

When asking them about US layouts they told me they won’t import from the US and that their competitor Steg Computer is importing US models. But I wasn’t comfortable with Steg and EeePCs also were more expensive there, so I hesitated ordering at Steg.

So it was quite unexpected for me when US models showed up on digitec’s website. (Interestingly I never received any mail from their advertised EeePC newsletter, not even when they added 2G models t their repertoire.)

So at the end of March (and therefore later as most other geeks ;-) I ordered an ASUS EeePC at digitec. For me, white laptops look like Macs (and Macs are for sissies or masochists ;-) — so I had no problems to decide that I want a black EeePC with US keyboard layout. 2G was to small for my purposes (and also not that much cheaper) and 8G not available. So I went with the 4G, since Debian doesn’t need so much space if you choose the right packages (i.e. neither or at least not that much of GNOME or KDE ;-). I preferred the 4G over the 4G Surf because of the bigger battery capacity (and not because of the webcam which I consider funny but useless:-).

Initially the delivery date was set the 28th of March. Then it was subsequently set to “beginning of April”, “mid of April”, “end of April” and “beginning of May”. It finally arrived on 8th of May. In the meanwhile there were reports that even the 4G has been equipped with the smaller battery of the 4G Surf because of some battery shortage after some battery plant burnt down. But fortunately the delivery problems with black 4G US models doesn’t seem to have its reason there and my 4G has a 5200 mAh battery (at least according to its label and ACPI).

I also ordered a 2 GB bar of Corsair ValueSelect RAM so that I can pump up the RAM of my EeePC by factor four (for about 10% of the price of the EeePC itself) resulting in having half as much RAM as disk space. Well, I guess, I won’t do suspend to disk in that configuration… ;-)

The original Xandros based Linux only noticed 1 GB of the installed 2 GB as already noted on many other places in the web. But that doesn’t really matter, since it only lasted until I found out how to restore it from DVD in case I want to sell the EeePC later (e.g. for getting the successor). It’s fine for novices, but Linuxes feel strange if you can’t even get a console or a terminal with a command line. ;-)

The Debian EeePC installer worked fine except that it argued over a checksum error on our mirror which wasn’t reproducable after the installation anymore. I’ve chosen the EeePC to be my first (nearly) pure Lenny installation — compared to the three machines running Sid (i386, amd64 and kfreebsd-i386). It though has a few packages from experimental (mostly xulrunner-1.9) installed.

As window managers I have installed ratpoison, FLWM and FVWM. ratpoison — best described as screen for X (although you can’t detach and reattach) since it’s my personal preferences for being productive without big screen resolutions and flwm for a low-resource window manager which can be used intuitivly by both, geeks and non-geeks (and still doesn’t look like Windows at all ;-). And FVWM is installed because it’s my default window manager on all machines with bigger or multiple screens – to be able to compare it with my usual environment.

As web browser I’ve got Opera as primary browser (as everywhere else, too) and Conkeror (the EeePC is the test-case for upcoming Debian package of Conkeror) as well as links2 and lynx on the (nearly) text-only side on it, although I need them seldomly.

As office programs (as I would ever need some ;-) I’ve got AbiWord and Gnumeric installed since I already use a few GNOME applications (e.g. Network Manager, Twitux, etc.) and OpenOffice.org would take up 170 MB more disk space (then including OOo Draw and OOo Impress) and Siag Office is no more in Debian since years. (Initially I had OpenOffice.org installed instead of AbiWord and Gnumeric until I noticed that I need some of the GNOME libraries anyway.)

I also decided that I will need LaTeX then and when so TeX Live also got its chunk of the 4 GB of disk space.

I also have a bunch of games on the EeePC. Unfortunately there are a few games which don’t work well on the EeePC due to it’s resolution being smaller than 800x600, so I deinstalled them already again, e.g. I can’t play Cuyo on the EeePC but flobopuyo. Sauerbraten segfaults, but Doom (prboom with freedoom WADs) works fine. Further non-working games unfortunately include Battle of Wesnoth and XFrisk.

Still, although quite some parts of GNOME and GNOME Office, TeX Live, ScummVM with Flight of the Amazon Queen and Beneath a Steel Sky, GNU Emacs 22, Iceweasel 3 (aka Mozilla Firefox 3), Icedove (aka Mozilla Thunderbird) and the Iceowl (aka Mozilla Sunbird) are installed, only 2.3 GB of the available hard disk space are used by the installation (i.e. without my home directory).

Oh, and btw: Although except the very compact and a little bit wobbly keyboard the EeePC doesn’t feel really small to me (I’ve got quite small hands), but when I sat down in front of my 14” ThinkPad T61 after a day or two with EeePC, the T61, — especially screen and keyboard — felt huge as if it would be some 17” or even bigger notebook. ;-)

OTOH I still think that a 1920×1200 (which means nearly four xterms in a row) resolution on a 14” notebook would be a good idea, especially compared to the 1440×900 (which means nearly three xterms in a row) my T61 has. ;-)

Personal Resumée after one month

Pro EeePC

• It’s geeky. If you show up with it, people want to lift it to see how much it weights and try the tiny keyboard. They’re surprised that 800x480 aren’t that small and that the performance isn’t that bad.
• Very compact and robust. With the T61 I always fear that its edges are too close to the the outside of my backpack and could be damaged that way.
• The price of course: CHF 499 at digitec (plus CHF 54 for the 2 GB RAM)
• Runs Linux ex factory. So yu don’t have to expect that many driver hassles.
• RAM upgrades are very straight forward and do not void the warranty. (BTW: The sticker over one of the screws which probably should prove the integrity can be removed and placed again easily… :-)
• The weight. 0.92 kg can be easily held wit one hand, also because of less leverage effect as with full-size laptops.
• The SSD despite it’s size. Being such lightweight you accelerate the EeePC unmindfully even when it runs. But it doesn’t matter, at least not to the hard disk. And it boots very fast, especially after the usage of insserv.
• Intergrated Ethernet network interface. (Hey, the MacBook Air hasn’t a builtin one, not even an external shipped with it! ;-)
• Three USB sockets (the MacBook Air has only one which is usually taken for the Ethernet network adaptor — Ok, with the EeePC usually one is taken for the Bluetooth dongle, but then are still two sockets left… ;-)
• Great contrast on the builtin screen.
• External VGA output. You have to configure X.org to make the virtual screen big enough (e.g. 2048×2048 instead of the default 800×800).
• Despite its size quite a lot of space for modifications inside the case. Especially a bluetooth case mode should be no big deal.

Contra EeePC

• The keyboard: keys smaller than usually (ok, wouldn’t work otherwise ;-), very wobbly, no precise contact depth (pressing Shift and Fn with one finger often doesn’t press Fn right), not all keys on the same plane, unusual offsets between the key rows (the number row has about half a key width offset to the left) or position of keys (I often hit Ins when I want Home, Del when I want Backspace or Fn when I want Ctrl, the ~ key is between Esc and F1, Up is between Slash and Right Shift, etc.)
• The position of the power button: It’s exactly where I want to put thumb when holding the EeePC solely with the right hand. And yes, I already accidentially switch it off several times because of that. For luck the button doesn’t work at all when the lid is closed, because you still can reach it easily while it’s closed.
• The mouse button(s): It only has two buttons which are one part you can press more to the left and more to the right side. And if you press it in the middle you randomly get either a left or a right click. You have to press it very hard to get both clicks at the same time. (e.g. to emulate a third middle button). Three separated mouse buttons would have been way better.
• It has (only) a touchpad. I definitely prefer thumbsticks as the ThinkPads have, but got used to it, though. I have seen worse touchpads, too.
• The noisy and not very precisely beared fan, which seems to strife its environment when the EeePC is being accelerated. Whih happens quite often because of its size and weight and because the SSD doesn’t mind acceleration. The fan does mind – and you hear it. :-(
• Some programs need minimum 800x600 resolution to work well.

Pro ThinkPad (in direct comparision)

• Thumbstick.
• One of the best laptop keyboards around.
• Three easy to distinguish mouse buttons.
• Even ressource-hungry programs like Liferea work fine.
• Quite big screen resolution (1440×900).
• Bigger battery, space for additional batteries.
• Could be a workstation replacement.

Pro Lenny on the EeePC

• The installer image of the Debian EeePC Project works out of the box. All necessary drivers are available, if you include the non-free repositories and the eeepc.debian.net repositories.
• Stable enough for daily use. (IMHO Debian Testing – and even Debian Unstable – is more stable as many other distribution’s stable releases, e.g. those from SuSE.)

Con Lenny on the EeePC

• My favourite feed reader Liferea has changed its cache format since the version in Debian Etch, so I can’t sync Liferea caches between my Debian Etch running T61 and the Testing running EeePC. Well, fortunately the version of Liferea in Debian Etch still works on Debian Lenny, so I just downgraded the package to the version from Etch and set it on hold. I don’t use it on the EeePC though since it needs way too long to start (about 10 to 15 minutes compared to 1 to 3 minutes on the T61)

Summary

I’m very happy with the EeePC and I didn’t expect that it would replace my 14” ThinkPad in so many (but still not all) situations. :-)

Goodbye Woody, Welcome Etch //at 10:54 //by abe

It finally happened. I installed Debian Etch on my last Woody box, a 400 MHz Pentium II with 576 MB RAM named gsa which is my home desktop since I bought it at LinuxTag 2003 in Karlsruhe.

And no I didn’t do a dist-upgrade, neither direct no via Sarge. As already planned I removed some no more necessary operating systems from that box and installed Etch on the freed disk space. Woody is still installed on that box in parallel and was recognized perfectly by Etch’s installer.

I took a few hours but also was big fun to go through Etch package list and to decide what to install. Overall the installation of 5 GB of software took about half a day.

In general everything went fine, the only thing I’m yet missing is sound. Etch didn’t seem to recognize my soundcard at all although it’s a well-known brand and defacto standard for many other soundcards: a Creative Labs Soundblaster. Well, the 16-Bit ISA version, needing the full length of the slot. Worked fine under Woody. Well, I hope I’ll get it working again manually.

What on the other hand is really nice with udev hell —eh— hal and all those new automatic bells and whistles: The desktop (well, at least GNOME Nautilus as well as XFCE, but probably also KDE) recognises when I insert a 3.5” floppy into the drive and shows me a nice floppy icon on the desktop. You think, that’s impossible? Floppy drives don’t inform the rest of the system when a floppy has been inserted without you polling the drive every few seconds? Well, USB floppy drives can. And they do. :-)

I still need time to migrate all the old settings from Woody to Etch. I’ll probably stick with FVWM, but perhaps will use the GNOME enabled version. What’s already done is the migration from tcsh to zsh. On all new or dist-upgraded systems after Etch I’ve chosen zsh so with my last Woody installation retiring I’ve also fully migrated to zsh.

So I’ve got now most of my active private boxes running Etch. Only the noone.org web and mail server “sym” (an amd64 box) as well as my 133 MHz ThinkPad “bijou” are still running Sarge, both with 2.6 kernels.

So with switching to Etch on gsa, I also got no more Debian box running a 2.4 kernel. The only 2.4 kernel I run is on my FreeWRT WLAN router named pluriel, which runs 2.4.33.3. But I expect that 2.6.18 will be as stable and long lasting as the famous and rock-solid 2.4.18 from Woody. 18 seems to be Debian’s favourite kernel minor version recently. ;-)
