Recently I found myself wanting to expose more and more internal web services to the outside. We have an internal mail caching server, ticket system, a handful of development sites, as well as several other internal web services that would be handy to access from remote locations. If you have internal dns, and your dns heirichy is sane you can probably use the same trick I did to allow any internal webservice that has a proper fqdn to work from outside your local LAN. I used Apache2, mod_proxy, and mod_rewrite. Only a few lines need to be altered in the default apache site install.
Working with virtual machines after having worked with physical machines can be a wonderful experience. Wonderful that is until the bios scree blows past you several times.
A few days ago I finally got my copy of Running Xen. I was anxious to see how the information would be presented. I can tell you I was not disappointed.
Bonnie is a great tool to use to benchmark your file system. Just a quick tip on using bonnie.
After more testing I have narrowed the issue that I left off with to a problem with the yum conf inside of the chroot.
At work I am just beginning the process of migrating from a hosted dedicated server to a Xen instance on a new server we have. Our dedicated server runs centos, and has WHM cpanel installed. So I figured it would be a good thing to have cpanel again as several people are familiar with it, and we do host a few random websites for people still. Cpanel does not support debian to my knowledge so Centos 5 sounds like the best way to go.
Recently I ordered a server with Debian etch. Unfortunately during testing I noticed that startx was on the system, along with a whole slew of other junk that I don’t generally want on a fresh server. I wanted to remove all of the cruft but I didn’t have the exact package list.
Im not a big fan of cpanel but I do manage a server that runs it. Recently some update was pushed down that caused about 50% of my users to not be able to access mail. It all boiled down to a permission issue that the cpanel scripts /scripts/mailperm did not take care of. Their scripts do not correct the permissions of the virtual user maildirs.
If you use multiwan with pfsense and like me you have issues making outbound ftp connections try disabling the userland FTP-Proxy application on the LAN interface. It may stop you from being able to do active ftp connections but at least you can use ftp. With it enabled I was unable to make any outbound ftp connections active or passive.
