I had a developer configure ssh, ftp and vnc.
The SSH is working just fine, but there are issues with VNC and FTP.
On our firewall ports 21,22,80,5900,5901 and 3306 are open..so should be no issues there
The Debian server is not behind NAT
Testing a connection to the ftp from a computer inside our network on the same domain:
1: Works perfect with port 21 and sftp port 22
Testing a connection to the ftp from a computer outside our network:
1: Work perfect with sftp port 22
2: Does not work with ftp port 21 and i get this message:
"Error: Connection timed out
Error: Failed to retrieve directory listing"
1: Does not connect to VNC server inside our outside our network
The service xtightvnc is running, but when i run jsof -i -P
i cant see anywere were it is writen that xtightserver is listening on port 5900
So looks like its not listening on that port
I need someone who is expert in this to fix both issues , you will get root access to debian server true ssh
Cant give VNC access since vnc is not working
Its urgen so need to get it fixed now
