Grub can't find my new kernel, when old kernel works and is in the same directory
by Srdjan Todorovic 25 Sep '09

25 Sep '09

Hi all, Decided to give Linux 2.6.31 a go to see if it fixes the annoying I/O slowness bug I've been having for a long time. Compiled it, installed the modules and copied the kernel image to the correct place in what is effectively /boot title Slamd 64 12.2 Linux 2.6.30-cfq root (hd0,1) kernel /boot/slamd64-2.6.30-cfq root=/dev/sda2 title Slamd 64 12.2 Linux 2.6.31-srki root (hd0,1) kernel /boot/slamd64-2.6.31srki root=/dev/sda2 The first entry works and I can boot it. The second entry does not work and I get a "Error 15: File not found" I've verified the kernel is in the same dir and the filename is correct - so no typos. Googling for this message shows some ubuntu related stuff about having to reinstall grub - I can't imagine why i'd have to do this given the previous entry works. I can't see what I'm doing wrong with the grub config - everything seems to be ok. Does grub have a size limit on the kernel image? The grub screen shows: Booting 'Slamd 64 12.2 Linux 2.6.31-srki' root (hd0,1) Filesystem type is ext2fs, partition type 0x83 kernel /boot/slamd64-2.6.31srki root=/dev/sda2 Error 15: File not found Press any key to continue.... Anyone kindly offer some help please? Thanks Srdjan

ssh-agent
by Richard Lewis 24 Sep '09

24 Sep '09

Hi ALUG, I'm trying to get ssh-agent to work properly so that I can have passwordless ssh. I've got my public key in the authorized_keys files on the relevant remote machines, and I can log in to them by just unlocking my key OK. The bit that I'm stuck with is starting ssh-agent properly. If I run urxvt, for example, under ssh-agent: $ ssh-agent urxvt I can't then run ssh-add, it says "Could not open a connection to your authentication agent." Although ps reports that the ssh-agent is running. The next thing I can't do is get ssh-agent to start my Fluxbox session. In /etc/X11/Xsession.options I have have "use-ssh-agent" (which I think is a default anyway). But I don't have any ssh-agent process running, and ssh-add reports the same error as above for a shell running under Fluxbox. (My /etc/X11/Xsession.options also has "use-session-dbus" and it seems that dbus works OK; I have a process called /usr/bin/dbus-launch --exit-with-session /usr/bin/startfluxbox. That's not exactly related, but I guess it's kind of similar.) Any ideas why this isn't working?

Debian dependency hell!!
by Ted.Harding＠manchester.ac.uk 24 Sep '09

24 Sep '09

Hi Folks, I have hit yet another instance of having an attempt to install a Debian package run into a dead end. For the sake of another package, I need mencoder (I already have mplayer) on a Debian Etch system (regularly upgraded). So I start up Synaptic, search for mencoder (which comes up in the search list), and mark it for installation. First result: NOT AUTHENTICATED: libpostproccvs51 To be installed: libfribidi0 liblzo2-2 libpostproccvs51 and I then choose to Mark these. Result: mencoder: Depends: libdvdnav4 but it is not going to be installed Depends: libmpcdec3 but it is not installable Depends: libtwolame0 but it is not installable This "not going to be installed" and "not installable" is a block which I frequently encounter. No reasons are given as to why "it is not going to be installed" nor why "it is not installable", which leaves me clueless as to what to do about it! There is no visible "help" button in this situation. Is there any work-round for this situation? While I like Debian when using what can be installed on it, I find this situation very irritating, and I'm beggining to get fed up with it. Enough to drive me to use Ubuntu! (Which I find too glitzy and "user-oriented" [yuk] for myh taste, but at least it seems to do this kind of thing effortlessly). Comments? With thanks, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)manchester.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 23-Sep-09 Time: 19:30:31 ------------------------------ XFMail ------------------------------

Document Management Systems
by Mark Rogers 23 Sep '09

23 Sep '09

Does anyone here have any experience/recommendations for web-based document management systems? Ie: a collection of users, each with (secure) access to different sets of individual and shared documents, via a web interface. I know there are several wheels out there which I could avoid re-inventing, but I don't have any first-hand experience of any of them. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

Corrupting address book file in icedove
by Jenny Hopkins 22 Sep '09

22 Sep '09

Hullo there, I'm having problems with a corrupting address book. One of my clients uses icedove aka thunderbird for her mail, and the address book is becoming corrupt on a daily basis. Googling has led me to a bug report in 2007 that never seemed to be resolved but i can find little else other than helpful instructions on how to uncorrupt the file. This problem started when the disk filled up to 100%, but even though space has been freed up the problem is continuing. The versions are running on lenny: ii icedove 2.0.0.22-0lenny1 free/unbranded thunderbird mail/news/rss clone ii thunderbird 1.5.0.13+1.5.0.15b.dfsg1+prepatch080614i-0etch1 Transition package for icedove rename Has anyone else experienced such a problem? Can anyone make any suggestions? System load is usually pretty small, but a large rsync file transfer does happen every lunchtime - seems to have no bearing on the random time of corruption though. Any hints welcome, Jenny

Anyone like Bing?
by Mark Rogers 18 Sep '09

18 Sep '09

I've just had to do a fresh Windows install so it still has its default search engine. Too lazy to type "openoffice.org" in the address bar I typed "openoffice" and let Bing find it for me. Or at least I thought it would, but it wasn't even listed. A few ads for downloads from non-OOo sites, and few references to it, but even adding "org" to the search didn't get me there. It's hard to see how that could be unbiased results! -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

Securing grub
by Dan Hatton 15 Sep '09

15 Sep '09

Dear All, I just frightened the life out of myself by selecting this option from my grub menu: title Gentoo Linux (rescue) root (hd0,4) kernel /boot/bzImage-2.6.28-tuxonice-r10 root=/dev/sda5 real_root=/dev/sda5 init=/bin/bb and finding it dropped me straight to a shell with root privileges, with no need to enter a password. Since the machine sometimes gets left unattended in areas other people have access to, I'd really like this not to be a possibility. But I would still like the possibility of a minimal-services, non-GUI boot. Any ideas, please? -- Thanks, Dan

DPMS trouble
by Dan Hatton 14 Sep '09

14 Sep '09

Dear All, I've posted about this before, but I can now give a clearer description of my problem (thanks to Tim Green for a tip that helped me get there). Any suggestions as to how to make DPMS work correctly will be welcome. I have two computers (say 1 and 2), both with built-in LCD screens, plus two external monitors (A and B) that plug into VGA ports. The results of running xset dpms force off (or going to DPMS off mode via xscreensaver) are as follows: Computer 1 + no external monitor: built-in screen goes to DPMS off mode. Computer 1 + monitor A: monitor A goes to DPMS off mode, built-in screen was in off mode anyway, from time computer was started with monitor A plugged in. Computer 1 + monitor B: monitor B goes to DPMS off mode, built-in screen was in off mode anyway, from time computer was started with monitor B plugged in. Computer 2 + no external monitor: built-in screen goes to DPMS off mode. Computer 2 + monitor A: both built-in screen and monitor A go to DPMS off mode. Computer 2 + monitor B: built-in screen goes to DPMS off mode, monitor B stays on, complaining that I should "check signal cable". So it seems all individual components work OK, and it's the combination of computer 2 and monitor B that's problematic. In each case, the monitor behaviour when the computer is switched off altogether is the same as that in response to xset dpms force off. Thanks very much, Dan Some details that might help: Computer 1 has an Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03), and runs Fedora 9 with xorg 1.5.2-6.fc9. Computer 2 has an Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03), and runs Gentoo with xorg 7.2. Monitor A is a Samsung SyncMaster 710N.
