Hi,
front door for a mainframe telnet session, is there any valid reason to even install telnet, rlogin, etc.?
Yes, if you need to update ssh remotly. sshd got a lot of security problems the last years, if you have to update it remotly you will enable telnetd for a short period to restart sshd after an update - if the update fails you will be locked out of a remote system :-)
I clearly disagree. I haven't needed telnet for a long time, not even for sshd updates. In case of severe fear, I copy the sshd to another name, start it on another port and log in via that instance. Then I can easily update, kill or reconfigure the main sshd. Markus -- __________________ /"\ Markus Gaugusch \ / ASCII Ribbon Campaign markus(at)gaugusch.at X Against HTML Mail / \
