VNC thru SSH

[pkroetsch]

I am testing out VNC with my new Linux Machine. RHEL 6 64bit.

I am very new to linux and I am trying to get the hang of it.

I can remote into my Windows Machine from my linux machine using just vnc and it works just fine but this is not secure.

I try to configure my ssh session through putty and I either get a black screen that shows nothing or I get a connection refused error when try to connect my ssh connection.

Any help is appreciated.

Thanks!

On the RHEL box:

Is the SSH daemon running?

service sshd status
netstat -tulnp|grep sshd

If not, start it:

service sshd start

Is the firewall getting in the way? Temporarily disable it:

service iptables stop

What is in your system logs?

tail /var/log/messages
tail /var/log/secure

When trying to log in with SSH/Putty, are you using a valid username for the RHEL box? The root account might be disabled by default. Also, check for a list of permitted users in the SSH daemon config file:

egrep -i ^'PermitRoot|AllowUsers' /etc/ssh/sshd_config

To get more details on the SSH config file:

man 5 sshd_config
