I wanted to post a procedure on updating certs for Postfix and Courier POP. I do this and forget, so this will be nice for the next time. First I delete the ‘demoCA’ directory rm -rf /etc/ssl/misc/demoCA Then I edit the CA.pl script since this may have been overwritten on openssl update. vi /etc/ssl/misc/CA.pl add… Continue reading Updating certs for Postfix and Courier
So udev-197 has been released as stable and in portage now. This requires a kernel config change, and if this is not in place, your server will be dead in the water. You will need to enable CONFIG_DEVTMPFS. Normally, this isn’t a problem, just build a new kernel and go from there, but I have… Continue reading Dealing with udev-197 and older virtual images at Rackspace
I have a client that needs to do large backups off site. Originally we were managing that with a offsite Linux server and dirvish, but it’s apparent that disk and bandwidth is going to be an ongoing issue. I wanted to look at other possibilities.
It is really uncanny that I run across these problems during the holidays. On Dec. 24 one of my boxes was reporting a “read only filesystem” on the /var partition. My alerts didn’t notify me since services were up, but mails weren’t happening and mysql was reporting crashed tables. The first time I was able… Continue reading Dealing with corruption on drives – reiserfsck –rebuild-tree how to
I ran into a few issues restarting this service after upgrading. The first issue was related to the location of dhcpd.conf. For some reason (even though CHROOT is clearly defined), the start up script is still trying to locate dhcpd.conf in /etc/dhcpd.conf. I had to create a symlink from the jail to /etc/dhcpd.conf. Can’t open… Continue reading Issues with dhcp-4.2.2 upgrade from dhcp-3.1.3_p1
Currently at Dell you can pick up a Dell PowerEdge T110 Server with a 24″ ViewSonic Monitor for ONLY $479!! Not bad if you’re looking for a file server. I personally love picking up these Dell servers at these prices. They’re great for file servers, test or production web servers, etc. They’re quiet, powerful and… Continue reading Great deal on Dell PowerEdge T110 Server!
I recently changed one of my web servers to use chroot apache. This particular web server also used ImageMagick for some of the sites there, so I needed to figure out how to get this to work. I came across this script.. that sorta worked, but it was enough to get it started. I’ll post… Continue reading How to get ImageMagick to work in chroot apache for Gentoo
I recently started using Rackspace Cloud Server environment to spin up a new Gentoo server for myself. The Cloud Server is pretty cool, and I’m finally starting to adopt it. Rackspace offers Gentoo images, which is great. After starting up the base image I was beginning the tedious process of updating world and getting some… Continue reading agetty spamming logs at Rackspace Cloud Gentoo server
So, again, I’m pretty much creating this blog post so in a year from now, when I need to renew, I’ll have a procedure on how to do it. For the longest time I’ve been using self-signed certs for mail, but needed to finally get a trusted cert (GeoTrust cert) in the picture. I went… Continue reading Adding trusted cert to Postfix and Courier-Imap
Here is another fun issue with linux that I had to deal with over the holidays. I figured since I was at my inlaws that I would do some updates on their various linux devices (firewalls mainly). I wanted to upgrade to 2.6.36-hardened-r6, but on reboot, I ran across a huge problem. VFS: Cannot open… Continue reading VFS: Cannot open root device “hda5” or unknown-block(0,0)
