Sshd Configuration

sshd should be enabled by default in both caos 2 and 3 and you can see if its running by the command

ssh -l your_login_name hostname_or_ip -c 3des

or you can do this command

/etc/init.d/sshd status

if you need to configure other options like the ssh port you will want to comment out the default lines in /etc/ssh/sshd_config then restart sshd

/usr/sbin/sshd restart

just typing sshd won't work trust me type the whole path

sshd is automatically started during boot for more information look here Startup scripts with service and chkconfig
