Kernel for 1&1 Servers....

http://faq.oneandone.co.uk/server/root_ ... cue/4.html

Has a little bit of info on the serial console - doesn't seem to apply to their older root server packages (in the UK at least) though.

TutanGeek - cheers for pointing out the 1&1 update server - saved me stumbling around in the dark for a long time, and my pooor little abused server is now back up and running properly once again

Chris.

BE WARNED !!!!

TO THE BEST OF MY KNOWLEDGE NO KERNELS ABOVE 2.4.25-040218 RELEASED BY 1&1 INCLUDE IPTABLES AND THEY SEVERLY EFFECT THE PERFORMANCE OF THE PLESK ADMIN TOOL!!!!!!!!!!


I TRIED kernel-2.6.9-041214 DISCOVERED THIS THE HARD WAY !!!!!!

I WOULD APPRECIATE ANY FEEDBACK ON THE OTHER KERNELS
kernel-2.4.26-040421
kernel-2.6.9-041110

Huh, they didnt include the netfilter code? Bizzaro. Well Im pretty sure that my latest grsec kernel is going to work just fine on 1&1 boxes. I just need a guineapig to test it out for me.

[dow]

<--- guineapig here---<< i have a server im going to image in a day or two anyhow moving the client to another network.

[scott]

catch me on IM and we'll coordinate

[dow]

ive sent a couple im's on yahoo no reply. are they being recieved?

[scott]

Hmm, Im guessing that Im not. Yahoo changes things from time to time that break clients like mine (gaim). Ill run the native client for a bit so I can test it out

I've run into the same issue (upgraded the kernel with a plesk upgrade, without realizing what damage it would do). Has anyone found any more information about a fix for this?

I can get to the server via the recovery console (1&1), and I can mount the drives, etc. If there's any way to roll back the kernel version or get it to boot to a different kernel, I'd be very thankful to hear it. I've got customers hosting websites and e-mail and I'd like to get this fixed before they all realize it's down.

Hopefully, I won't have to re-image the server...

Login to your server via the recovery console.

Run

Code: Select all

mount -t ext3 /dev/hda1 /mnt/
mount -t xfs /dev/hda5 /mnt/usr 
mount -t xfs /dev/hda6 /mnt/var 
mount -t xfs /dev/hda7 /mnt/home
chroot /mnt/
cd /root

If your using the 2.6 kernel run

Code: Select all

wget ftp://update.onlnehome-server.com/local-updates/kernel-2.6.9-041214.tar.gz
tar xzf kernel-2.6.9-041214.tar.gz
mv -f boot/* /boot/*
mv -f lib/modules/2.6.9-041214 /lib/modules/
cd /boot
ln -sf vmlinuz-2.6.9-041214 vmlinuz
ln -sf System.map-2.6.9-041214 System.map
lilo

If your running the 2.4 Kernel do...

Code: Select all

wget ftp://update.onlnehome-server.com/local-updates/kernel-2.4.26-040421.tar.gz
tar xzf kernel-2.4.26-040421.tar.gz
mv -f boot/* /boot/*
mv -f lib/modules/2.4.26-040421 /lib/modules/
cd /boot
ln -sf vmlinuz-2.4.26-040421 vmlinuz
ln -sf System.map-2.4.26-040421 System.map
lilo

Set your server to Normal mode from the 1and1 control pannel and run....

Code: Select all

shutdown -r now

When I try to make the second mount, I get the error "mount point /mnt/usr does not exist". Do I need to create this directory first?

nope because the first mount should be / which will have folders for usr var and home.

Whats the output of fdisk -l ?

also after you do the fist mount what is the output of

ls /mnt/

[kwebdesign]

I think the problem is that hda1 is my boot partition. The root partition is hda3

[kwebdesign]

Here's the output of fdisk -l

Device Boot Start End Blocks Id System
/dev/hda1 * 1 33 265041 83 Linux
/dev/hda2 34 131 787185 82 Linux swap
/dev/hda3 132 4865 38025855 83 Linux

I take it you've had your server for a while because they haven't been using that partion setup for a long time.

Use the following commands to mount instead.

mount /dev/hda3 /mnt
mount /dev/hda1 /mnt/boot

Then continue on from (including)

chroot /mnt/

[kwebdesign]

Woo-hoo! It's back on-line! Thanks so much, Jason. I appreciate it more than I can tell you.

I've had this server for just under a year. It's a RH9 server - probably one of the last ones they set up. I think that's part of what has confused me - everything I've read about this problem elsewhere assumes FC2 and a different configuration.

Everything appears to be working now, and I will avoid kernel upgrades that aren't issued by 1&1 in the future.

Thanks again.
