Just got a new cPanel server, but it did not have telnet installed. So I installed it with: yum install telnet I need it for performing tasks like the following at shell: telnet somemailserver.com 25 (to see if port 25 is accepting connections). But then I remembered all the dire warnings about now un-secure telnet is. So I went for my very old instructions to disable telnet, which are still commonly given out, but these do not work: pico -w /etc/xinetd.d/telnet change disable = no to disable = yes Save and Exit the file and then type below command: /etc/init.d/xinetd restart After doing: pico -w /etc/xinetd.d/telnet I get pico just opening a new file, i.e. there are no telnet settings there. So what's the scoop on telnet these days? I use SSH but only with encryption keys, no password access to shell is available. In this situation is telnet still dangerous? Or even if I had password SSH access going, would telnet be dangerous then? And where are the telnet configs these days? So may questions, so few corn chips.
