Having been accomodating about it in the past, the technical geniuses at Comcast have permanently blocked port 25, separating me (at my home office) from my employer's e-mail server. What can be done on the server side to keep Postfix listening on 25 _and_ accept my connections on some other port? Is there a Postfix solution? iptables maybe? Miark

My wife's office server was compromised today. It appears they ssh'ed in through account pcguest which was set up for Samba. (I don't remember setting up that account, but maybe I did.)

I've seen several references to running VMWare under CentOS, but does anybody know how well Parallels runs under CentOS? On a related note, now that Zen is as mature as it is, are commercial VMs really much better than Zen? Miark

I'm trying to use rsync to synchronize customer application files across multiple WEB servers. The actual copying of the files works fine. The problem is that it changes the selinux security context of some of the files. Since there are over 2000 files for each customer, it becomes a major issue to correct the security context after the fact as not all have the same context. Searching the

Background: I am in the habit of making bootable GRUB CDs with menus and copies of working kernels and initrds, particularly for multiple-boot testing machines with multiple distros and/or the Redmond OS. This has helped pull my fat out of the fire more than once when a system was rendered unbootable by hardware changes, or when Bill Gates decided the MBR should be taken over. This generally
