Debian hanging on boot at udev
Filed Under:
Debian
It seems it is libnss-ldap which is causing udev to hang. Removing it does fix the issue, but we still need ldap, so I don't know what the full answer is yet.

Optimize your ext2/ext3 filesystem
Filed Under:
Debian
This is a repost from here: http://blog.drinsama.de/erich/en/linux/2006060401-optimize-your-ext23-fs
...use tune2fs -l /dev/hda5 | grep features to get a list of your filesystem features. If you have "dir_index" in there then you're all set. Ignore any "needs_recovery" - that is good for mounted filesystems (it just means "not cleanly unmounted")To add dir_index, do the following.
- Unmount the filesystem. If this is your primary filesystem, use a bootable CD like Knoppix or some Linux install CD.
- Make sure the filesystem is really not mounted. Just for safety of your data. Run e2fsck /dev/hda5 - this should take less than one second if your filesystem is clean and is needed anyway otherwise...
- Execute tune2fs -O +dir_index /dev/hda5 to enable the feature for your filesystem
- Execute e2fsck -Df /dev/hda5. This will force a filesystem check with directory optimization (!) on your filesystem.
- Mount your system (or reboot, if you were using a live CD)
Network Manager doesn't find devices
Filed Under:
Debian
After upgrading network-manager from 0.6.2-1 to 0.6.2-3 none of my network devices show up. This is due to a change in the way devices are enumerated. If your device is listed in /etc/network/interfaces then it will not be managed by Network Manager. So deleting all references to non lo devices solved the problem.
