[Lias] enabling telnet services

[Andrew Dorrell]

Hi Frank,

Leave the ipchains stuff alone...
start sshd using /etc/init.d/sshd start
(and add it to the run level so that it is started automatically when
booting using chkconfig --level 345 sshd on)

then you should be able to ssh to your machine.  The first time you do
this however it may complain about strict host key checking.  if so,
just for the first time, use the command:

ssh -o StrictHostKeyChecking=no othermachine

(or change the value of the StrictHostKeyChecking option to "ask" in the
global config file /etc/ssh/ssh_config)
