Network devices - stop automatic connection
by Frank Eisenblaetter 09 Feb '07

09 Feb '07

I use grml on hd. 1) I have configured my networdevices at /etc/network/interfaces. There is no automatic ifup configured in it, but if I am connected to my router the networkconnection get's automatically established on startup of the system: * Network device eth0 detected, DHCP broadcasting for IP (Backgrounding) I think the connection get's established because an init script detects my networkdevice an runs a DHCP-client butI dont't know which script it is. How can i stop the autoconnection of my network device(s)? Or is there an other grml/debian way of configuring network devices? 2) On system startup I get the message: EXT3-fs warning: maximal mountcount The message tells me that I should run e2fsck. Why isn't this done automatical as it is on any other linux I uses before? Frank

Sendmail hostname error
by ][ 08 Feb '07

08 Feb '07

Hi, I wasn't able to use sendmail recently. I've now track it down that the hostname that my Sendmail uses is wrong. How can I fix it? % /usr/sbin/sendmail -bi WARNING: local host name (;; connection timed out; no servers could be reached) is not qualified; see cf/README: WHO AM I? /etc/mail/aliases: 24 aliases, longest 10 bytes, 233 bytes total % grep 'WHO AM I' -r /etc/mail/* || echo no found no found Please help. FYI, this is the respond that I got explaining why it is happening. _________________________________________________________________ You seem to be a victim of the same broken "helpfulness" as described in the (apparently misthreaded by google) thread at http://groups.google.com/group/comp.mail.sendmail/browse_frm/thread/7095fe4… - i.e. some install script or whatever has "configured" your sendmail with a *host name* of literally ";; connection timed out; no servers could be reached"! This is actually an error message from the 'dig' command - i.e. the script probably tries to use 'dig' to get the fully-qualified host name, and blindly accepts any output from 'dig'. The slightly different greeting comes from the fact that sendmail inserts the "ESMTP" there as the second word, under the reasonable assumption that the host name is a single word... _________________________________________________________________ -- Tong (remove underscore(s) to reply) http://xpt.sf.net/techdocs/ http://xpt.sf.net/tools/

Grml initrd
by ][ 08 Feb '07

08 Feb '07

Hi, I've been trying for several weeks to make my grml USB pen bootable. I think I finally found the problem, quite a simple one -- I need a initrd which has findfs to find the root device. However, I didn't find a initrd in my grml2hd disk, and neither the minirt26.gz borrowed from grml_small_0.3.iso works. So, is there anywhere I can get a grml initrd, or I have to build one myself? If so, any good source of info for the building? thanks PS. Here is what I get: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) My grub menu.lst: title Debian Live root (hd0,1) kernel /boot/vmlinuz root=UUID=b53f0a8b-deab-40b3-a84c-0779cb8b7772 ro initrd /boot/minirt26.gz boot title From grml.live root (hd0,1) kernel /boot/vmlinuz root=LABEL=grml.live ro initrd /boot/minirt26.gz boot -- Tong (remove underscore(s) to reply) http://xpt.sf.net/techdocs/ http://xpt.sf.net/tools/

Loop mount not automatically cleaned
by ][ 08 Feb '07

08 Feb '07

Hi, I noticed that loop mounts are not automatically cleaned in my system. Is there any way that I can fix it? Each time after I loop mount, the loop device number increased. When I do ps, I found that there are many loop process in execution: $ ps -eaf | grep loop root 5566 1 0 Jan05 ? 00:01:44 [loop0] root 5597 1 0 Jan05 ? 00:00:00 [loop1] root 5603 1 0 Jan05 ? 00:00:00 [loop2] root 10995 1 0 00:28 ? 00:01:41 [loop3] root 26656 1 0 11:42 ? 00:01:40 [loop4] root 6234 1 0 17:45 ? 00:00:00 [loop5] Previously, the loop process will be gone after I umount the loop mount. As the result, my disk space did not re-gain after deleting loop mounted iso files: sudo mount -o loop my-big.iso /mnt/tmp1 $ df /dev/sda14 79631676 52241640 27390036 66% /lfs/cache12 /dev/loop3 4571190 4571190 0 100% /mnt/tmp1 sudo umount /mnt/tmp1 $ lsof | grep my-big rm my-big.iso $ df /dev/sda14 79631676 52241640 27390036 66% /lfs/cache12 The my-big.iso is over 4G in size, but there is no space increase after it being deleted. I've checked with lsof that no one is using it. please help. thanks -- Tong (remove underscore(s) to reply) http://xpt.sf.net/techdocs/ http://xpt.sf.net/tools/

interfaces
by harry meyers 07 Feb '07

07 Feb '07

My wireless interface is eth1 In /etc/network/interfaces the according lines are simply: ,---- | iface eth1 inet dhcp | wpa-passphrase waaskaaner | wpa-ssid irgdnwoos `---- Under debian I had no problems with this configuration. But under grml the interfaces are often changed, so eth0 comes up instead fo eth1, which of course doesn't work. As a workaround I wrote a small script which changes everything and restarts networking but gradually it became quit annoying. What can I do? harry

Boot by UUID or disk label
by ][ 03 Feb '07

03 Feb '07

Hi, Grml wiki indicates that grml can use disk labels/UUIDs as root= option for booting [1]. What's the correct syntax for that? [1] http://wiki.grml.org/doku.php?id=usb&DokuWiki=88eb0d5110993c6c4d0ca5992abee… I searched hard and came up with the following, trying to boot my USB key: title GRML on 1st HD root (hd0,1) kernel /boot/vmlinuz root=/dev/disk/by-uuid/b53f0a8b-deab-40b3-a84c-0779cb8b7772 ro boot title GRML on 1st HD root (hd0,1) kernel /boot/vmlinuz root=/dev/disk/by-label/grml.boot ro boot title GRML on 2nd HD root (hd1,1) kernel /boot/vmlinuz root=/dev/disk/by-uuid/b53f0a8b-deab-40b3-a84c-0779cb8b7772 ro boot But all gave me root filesystem not found error (grub boot normally, just can't find root fs). I'm sure the uuid and disk label are correct. What else could be the problem? thanks -- Tong (remove underscore(s) to reply) http://xpt.sf.net/techdocs/ http://xpt.sf.net/tools/

nohwcap
by Erich Minderlein 31 Jan '07

31 Jan '07

Hello I refer to my posting http://www.mail-archive.com/grml@mur.at/msg00781.html in which a whole discussion thread deals with the subject. It had also been relayed to the maintainers of x-servers x.org IMHO the nohwcap issue shall be dealt with only by the kernel and / or any other hardware related software, which are currently the Xserver and the drivers only (in case of insertion / removal of hw). No application should try to find something out about hardware. Kernel shall do it once after booting, insertion or removal of hw only and then hold the data in its virtual filesystem. then such a weird device as /etc/ld.so.nohwcap is at best not existing or second best once read updated during system boot, insertion or removal of hw. best regards a system engineer -- Erich Minderlein <erminderlein(a)locoware.de> MARC Mannheim Rail Commerce GmbH

sarge and kernel 2.6.18-grml

Am Freitag, den 26.01.2007, 12:00 +0100 schrieb grml-request(a)mur.at: > sarge and kernel 2.6.18-grml (Erich Minderlein) Hello I repeat this mail _console and keyboard_ I did not post a question in this mail, so it has been overlooked. I removed console-terminus from the stable(sarge) package(250 kByte) and installed console-terminus from the testing(etch) package(565 kByte). Adding SCREEN_FONT=Lat15-Terminus16 in /etc/console-tools/config did not help; rebooting, prompt login as root, the normal font with serifs shows up, if I type unicode_start: answer : already in UTF8 mode after some fiddling around, I remove /etc/console-tools/config.d/fonty and /etc/console-tools/config.d/ and now it boots and changes to Terminus 16 for all consoles. This will probably not survive an update of package fonty! --Meanwhile fonty removed without negative consequences. Small Umlaut "ae,oe,ue" is properly printed on the console Capital Umlaut "Ae,Oe,Ue" and "scharf S"or (sz) like greek beta is not printed on the console, but results in circumflex accent ^^^^ dpkg-reconfigure console-common and dpkg-reconfigure console-data do not help, sometimes after testing these umlauts the console crashes and I get a new boot-prompt. regards I think the events described are severe: pressing Capital Umlauts Ae Oe Ue leads to console possibly exit or crash Is is a bug in the console-terminus package or is it a bug in the keyboard driver or is it a bug in the interfaces associated with these packages and the kernel ? Is it a bug between sarge and etch ? Is it a bug in front of the display ? All that is possible. I believe that I have exhausted all combinations of rebooting, installing fonts and keyboard drivers, .... Do I have to adapt /etc/console-tools/remap ? I add the result of showkey > somefile kb Modus war UNICODE Taste drücken (Programm beendet sich 10s nach dem letzten Tastendruck)...) 0x9c There are two funktion keys on the keyboard: Key Enveloppe press 0x00 0x81 0x9b release 0x80 0x81 0x9b key (i) Information symbol 0x00 0x81 0x96 0x80 0x81 0x96 kb Modus war UNICODE Taste drücken (Programm beendet sich 10s nach dem letzten Tastendruck)...) key "Ae" 0x28 0xa8 key "Oe" 0x27 0xa7 key "Ue" 0x1a 0x9a key Return 0x1c 0x9c Now from comparing the latter with the first, .. first UTF8 then UNICODE The latter was today immediately after a system boot. Small äöü (ae oe ue) work fine, capital Ae Oe Ue dont show on the console and result in three circumflex accent ^^^. Console specialists, what are the consequences ?

T2 Linux build harness
by Mark 29 Jan '07

29 Jan '07

OK, this tip might not be exactly right for grml, but still: since grml is working on new processor architectures like PPC and 64-bit x86 (and don't forget 64-bit PowerPC!). T2 Linux is all about re-targeting. It impressed us by booting obscure machines on which other "ported" distributions croak. It runs many OEM eval boards. There might be ideas here to help porting work. Just fyi. http://www.t2-project.org/about.html "T2 is highly portable. Adding new architectures is easy and can be done within a day!"
