 Posted by Jason on Friday October 12, @11:42AMfrom the stop-telnetd-service dept. I am sure that by now most users are aware of the dangers of using a remote connection which uses clear text passwords over the internet (e.g. telnet). Did you know that prior to FreeBSD-4.4-RELEASE the telnetd daemon had a bug which potentially granted root access to remote users via a buffer overflow exploit? If you have a version of the OS prior to July 2001, you should secure it by disabling telnetd. It's a very simple security measure. All you have to do is edit /etc/inetd.conf and comment out the line that starts telnetd. Login: root Restart your host and telnetd wil no longer be running. You can also just restart inetd like so: killall -hup inetd If you wish to login to your FreeBSD host remotely, use a secure connection like ssh. To learn more, read the man pages. man inetd < | >
