Hi Guys,

I've connected to a remote host sigma with ssh. When I attempt to connect back to my local system from the remote host I get the following message:

Secure connection to Selusa refused.

Why is that? How do I fix it?

Uhm, maybe check if sshd isn't running on Selusa?;
elif firewall denying?;
else Sshd using TCP Wrappers to deny?
(fi)

How do I check if sshd is running?

I was able to ssh into sigma from Selusa.... that means taht sigma has sshd running.. does that necessarily imply that Selusa has it running? if not, how do I enable?

Sonny.

When you connect with a client (ssh on Selusa) to a server (sshd on Sigma), this doesn't imply nor need sshd running on Selusa for this to work, only if you want to ssh from Sigma back to Selusa.
To check if Sshd is installed running "find /usr -name sshd -print" or "whereis sshd" will show you, the config files are in etc/ssh(d). If your distro uses Sysv stylee starting of daemons you'll find the startscript as /etc/(rc.d/)init.d/sshd, it will take care of generating the server RSA/DSA keys and start sshd with the necessary options (edit sshd_config before starting it).
