Opening Port 22

[Tinker Tantrum]

When I type in this command:

ssh localhost

I get this output:

ssh: connect to host localhost port 22: Connection refused

My question is: How do I disable the firewall for Port 22.

FYI: I am following the examples in a .pdf book called "The Linux Command Line by William E. Shotts,Jr.".

Is the ssh server (sshd I think) running on your local system? It sounds like there is nothing listening for incoming ssh connections.

You have to install and start openssh-server

[whitethorn]

Have you installed the SSH server and started it?

https://help.ubuntu.com/10.10/server...sh-server.html

Have a read here, it'll help you get ssh up and running. Once it's running you can then connect to localhost.

AH HA! That was it. Thanks everyone.

You need to be very careful if you are forwarding Port 22 on your Router.

That PDF Document states "if the system is either running or is behind a
firewall it must allow incoming network connections on TCP port 22."

But, if you are on your LAN (Local Area Network) and not connecting via the
WAN (Wide Area Network), then you DO NOT need to Forward Port 22 on your
Router. By forwarding your Router's Port you will be continuously attacked
by others in foreign countries, etc. You can verify this in your logs.

Try playing on your LAN with the Port not Forwarded, or Forward a Higher
Numbered port (50000) to your Routers Port 22 for SSH, and use KEYS, not Passwords.
That will prevent access attempts.

Don't be fooled into thinking your system is SAFE & SECURE, with your Routers Port 22
forwarded.
