ssh : connection refused

[leonardevens]

I just got a new laptop running ubuntu 8.04. It is on a local network, and I can ping its ip address, so I know it is there. I also have another machine running Fedora. I can ssh and scp from the ubuntu machine to the Fedora machine, but when I try to ssh in the reverse order from the Fedora machine to the ubuntu machine, I get "connection refused".

I presume something has to be reconfigured? What?


More generally,

I am pretty familiar with Fedora and other RedHat like Linuxes, so I would know what to look at if the situation were reversed. But I can't ffind familar commands under Ubuntu.

What corresponds to iptables under ubuntu, for example?

What command is equivalent to /sbin/service?

Is there somewhere that I can find a list of differences between these different Linuxes? Anything for a quick summary of how to use ubuntu?

By default, Ubuntu desktop doesn't run any services. So you need to install OpenSSL, run the sshd daemon and enable port 22 incoming in your firewall.

Use "ssh -vvv user@server" to debug ssh connections.

Have you installed the openssh-server package? There's a short decent tutorial here (http://www.cyberciti.biz/tips/howot-install-ubuntu-linux-ssh-server.html) (use or omit the change to port settings at will, I personally don't use port 22 forwarding at the router level).

Iptables is the same for ubuntu, and the services are found in /etc/init.d/

So for example for apache
/etc/init.d/apache2 start|stop
