[Gllug] Ssh Debugging

Dear GLLUGers,

I've recently upgraded to FTTC from Plusnet and now get 20+
Mbps download speeds.

The downside appears to be that my ssh link to my work
machine goes down five or six times a day.  So, I'm trying
to run sshd in debug mode on my work machine.  However, this
is what I get.

[root at penguin log]# /usr/sbin/sshd -d -p 1234
debug1: sshd version OpenSSH_3.9p1
debug1: private host key: #0 type 0 RSA1
debug1: read PEM private key done: type RSA
debug1: private host key: #1 type 1 RSA
debug1: read PEM private key done: type DSA
debug1: private host key: #2 type 2 DSA
debug1: rexec_argv[0]='/usr/sbin/sshd'
debug1: rexec_argv[1]='-d'
debug1: rexec_argv[2]='-p'
debug1: rexec_argv[3]='1234'
debug1: Bind to port 1234 on ::.
Server listening on :: port 1234.
debug1: Bind to port 1234 on 0.0.0.0.
Bind to port 1234 on 0.0.0.0 failed: Address already in use.
Generating 768 bit RSA key.
RSA key generation complete.

Presuably this means that the server is using a default IP
address of 0.0.0.0.  How can I overcome this?  Or is there
another error waiting in the wings?

Your help is appreciated.

Regards,
