I am attempting to VNC access a server through a RaspPi B+ running Raspbian. I can access the server fine using ssh; however, the pi unit seems to have port 5901 and 5902 blocked.
I am VPN'd into the server using openvpn. I am not sure if this makes any difference.
The results of the
netstat -natp command result in the port 5901 having a status of "sync sent". I have seen similar instances when a firewall is blocking a port from sending data out, but I do not have iptables active. I actually installed ufw and allowed out port 5901 to see if that helps, which it doesn't.
A linux laptop and an Android cellphone have no troubles connecting to this server. The laptop uses xvncviewer; this is what I am attempting to use on the pi unit.
