May 9, 2007 1 #3 TSch Technical User Jul 12, 2001 557 0 0 DE Hi there, you have to edit the /etc/inetd.conf file. Just remove the # in front of the line containing the telnet entry. After that perforam a refresh -s inetd and if that does not work restart the subsystem using stopsrc -s inetd startsrc -s inetd There's no need do reboot. However ... Telnet should be enabled by default on your system. How comes it is disabled ?? Regards Thomas Upvote 0 Downvote

May 9, 2007 #6 TSch Technical User Jul 12, 2001 557 0 0 DE Now that's strange ... This is supposed to do the trick. Well, let's see ... First of all the inetd.conf line should look like this: telnet stream tcp6 nowait root /usr/sbin/telnetd telnetd -a What do you get, when you run ps -ef | grep inetd ? The process must have the current date if you did a stopsrc and startsrc ... What's the output of lssrc -a | grep inetd ? Does the process number shown there change when you perform another stopsrc and startsrc on inetd subsystem an the repeat the lssrc command ? Anyway the subsystem should show up as "active" ...

May 9, 2007 #7 TSch Technical User Jul 12, 2001 557 0 0 DE Here's another thing you might check: Is there a file existing on your machine called /etc/hosts.allow /etc/hosts.deny ? If so rename these files (e.g. hosts.allow.save / hosts.deny.save), restart the inetd subsystem and try again to telnet to your machine ... Regards Thomas Upvote 0 Downvote

But a stopsrc and startsrc on inetd can never hurt ;-) Did the line look like this ? #telnet 23/tcp # Telnet ? Then it's ok to delete the # Don't delete the # behind 23/tcp You might also check, whether your user is telnet enabled using smitty user There should be a line containing User can LOGIN REMOTELY(rsh,tn,rlogin) This has to be set to "true".
