Ports for remsh and rlogin

[Mehul_5]

I want to access a server that is behind firewall. Which ports should be opened for remsh and rlogin services?

[melvyn burnard]

try looking at /etc/services
login 513/tcp # remote login
shell 514/tcp cmd # remote command, no passwd used

Hi mehul

If u have linux server with nmap installed (Which comes by default) do a port scanning with it.

Try `nmap ` .

This will scann all the ports in the mentioned ipaddress server and will show you the results.

Port 512/tcp : rexec (passwd reqd)
port 513/tcp : rlogin (passwd reqd)
port 514/tcp : remsh (no passwd reqd)

More info in /etc/services file.

You should also know that r-commands are not
secure and should be avoided.
