Authenticating Internet Users by greEd - 3/12/08 I had a job where I needed to install a authentication gateway in a existing network without disturbing the current gateway. To set this up I decided to use VMware on the head server. I setup OpenBSD 4.2 as the virtual machine because of the small footprint and low impact it would have on the server. Setting up pf and authpf couldn't have been easier. The setup was similar to tip #35 (Creating a Captive Portal With Authpf) with the exception that the authentication gateway sits in front of the existing internet gateway.  |
Ubuntu Server FSCK! by greEd - 2/26/08 A Ubuntu 6.10 Server I was working on recently decided on reboot to run a fsck check, there’s nothing wrong with this except it kept pushing me to a maintenance shell at about 76% stating: /dev/hda1 contains a file system with errors, check forced. /dev/hda1: Inode 5849438 has illegal block(s). /dev/hda1: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. (i.e., without -a or -p options) fsck died with exit status 4 After playing with fsck for a while I decided to reboot Ubuntu with the live CD. Once the system booted I tried fsck manually: sudo fsck -av /dev/hda1 Still no love. I was still getting errors such as: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY I then tried: sudo e2fsck -fyv /dev/hda1 After running this command I was able to get the system to successfully reboot. I'm still noticing odd errors reported about the drive so I'll replace this drive but this was good enough to get the system back up and running. |
