Full Discussion: ssh-ing to port 80.
Operating Systems Linux Red Hat ssh-ing to port 80. Post 70586 by jolok on Monday 2nd of May 2005 08:39:08 AM

Telnet doesn't really have to "be running", the way you mean. To test whether a machine is running a service on a port, you can generically 'telnet host port'. The whole "use ssh" thing really means "if you're logging into you machine remotely, use ssh, because it's encrypted, telnet isn't, so you're potential passing a plain-text password over the 'net." which doesn't pertain here. For your purposes, 'telnet localhost 80' will do just fine. You'll want to use ssh when you're actually logging into the machine remotely.

NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling SYNOPSIS
hostname | user@hostname [-l login_name] [command] hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name] [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command] DESCRIPTION
