Hiding your OS name and version will do nothing to increase security, because the majority of people who scan for vulnerable hosts just do bulk scanning, trying their trick on everything they find. They know (or just don't care) that you can't reliably determine the OS without shell access and even then you can be tricked. That said, what you're looking to do is change the banner on the daemons you're running. How you do this is specific to each daemon. As usual, RTWP, JTML, RTFM, RTSL, etc. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
