My Stuff

Stuff changed in herbie (needs to be changed on herbie hard drive):

• links to matlab binaries wrong on herbie hard drive
• /etc/profile has uw matlab license variables commented out on herbie hard drive
• did updates
• removed nvidia-glx (don't think this actually matters, didn't solve problem, problem was permissions on /tmp)
• installed lsb-core (regular debian package using aptitude) for matlab license manager
• installed torque-2.5.9, can find in /home/maria/

Notes for debugging with initrd: after editing files in /usr/share/initramfs-tools/ (make sure have copies of originals):

rm /tftpboot/initrd.img /tftpboot/kernel
cd /usr/src/linux-source-2.6.26/arch/x86_64/boot/ 
# if I was previously using initramfs for local boot initrd:
cp /etc/initramfs-tools/initramfs-nfs.conf /etc/initramfs-tools/initramfs.conf
# to change things in initrd.img, go to /usr/share/initramfs-tools/scripts
# keep copy of files you change.
mkinitramfs -o /tftpboot/initrd.img
wraplinux -i /tftpboot/initrd.img -p "root=/dev/nfs ip=dhcp nfsroot=10.208.108.18:/tftpboot/oscar" --output=/tftpboot/kernel bzImage
scp /tftpboot/kernel ella.shadlen.org:/var/www/gpxe/bz3Image

try it!

after done mucking about with initramfs-tools, put things back:

cp /root/nfs.initramfs-tools /usr/share/initramfs-tools/scripts/nfs
cp /root/udev.initramfs-tools /usr/share/initramfs-tools/scripts/init-bottom/udev
cp /etc/initramfs-tools/initramfs-local.conf /etc/initramfs-tools/initramfs.conf

Automount on leopard was driving me nuts. I couldn't find out why it wouldn't work. Messages on the server talked about an requests to mount on an insecure port (mac client log just said mount_nfs Operation not permitted), but I was using the -P option in the Directory Services mount options box. Apparently it was ignoring that option. Finally I stuck it in /etc/autofs.conf as a default for automount:

AUTOMOUNTD.MNTOPTIONS=-P,nosuid,nodev

and then automount started using the correct port. Automount is now requesting all sorts of files that do not exist, so my server log file is filling up with messages like this:

can't stat exported dir /home/.hidden: No such file or directory

Ugh.

to find out what is tying up a drive so you can't unmount it:
lsof +D /mnt/stuff

gently restart a frozen system: from http://lifehacker.com/software/linux-tip/gently-restart-a-frozen-system-298891.php

1. Hold down the Alt and SysRq (Print Screen) keys.
2. While holding those down, type the following in order. Nothing will appear to happen until the last letter is pressed: REISUB
3. Watch your computer reboot magically.
