The problem with telnet, is that is a trivial task to sniff passwords, so if you login as root over telnet, others can pick up your root password. Then, once they've got that, they can telnet in themselves as root. You want to investigate the use of 'su', so create a user who is in group wheel, and then let them login and su to root. You should also start considering the use of ssh instead of telnet. There are ssh clients for Windows, Mac, etc. as well as Unix. This in itself gives you a little more security as the password never crosses the wire in plaintext... Of course, if you really, really, really, REALLY had to be able to telnet in as root (you don't, I don't care what you say, you're just trying to break things for no good reason! :) ), then you need to look at /etc/ttys and change the entries under ttyp* to make them 'secure' (do a 'man 5 ttys' if you're not sure). -- Paul Robinson - Developer/Sys Admin @ Akitanet http://www.akitanet.co.uk ------------------------------------------------------------------------ Sales: T:+44 (0)1869 337088 F:+44 (0)1869 337488 E:sales@akitanet.co.uk Techs: T:+44 (0)161 228 6388 F:+44 (0)161 228 6387 E:root@akitanet.co.uk ------------------------------------------------------------------------ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
