Hi, you don't *have* to reboot the server. If you don't there are two factors you need to consider: 1. The updated component are not all active without a reboot The kernel for example will obviously not not be running without a reboot and the same may be true for other components. For most applications you should be ok if you just restart the application so it can load in the new

Hi, from man yum.conf: ip_resolve Determines how yum resolves host names. `4' or `IPv4': resolve to IPv4 addresses only. `6' or `IPv6': resolve to IPv6 addresses only.

Been working on my anti-spam centos mailserver for a while now and thought I would share fail2ban's help. I installed fail2ban a few weeks back. It was tough to get it working properly but pretty much working now. Although it works fine for brute force, I thought I would run it pretty tough against spammers. I started with a regular mail server, my old one, that is horrendously pounded

I'm running a mix of CentOS 5 and 6 servers reachable by ssh from the Internet. Of course I allow only public key authentication and no root login. In addition I'm running fail2ban to block obnoxious brute force attack sources. On CentOS 6 this is working pretty well, but on CentOS 5 there's one class of attacks fail2ban fails to ban. (No pun intended.) This isn't fail2ban's
