Dec 19, 2012 · For example, could you install UltraVNC (another remote desktop connection) on the same server and on the host attempting the connection and try to connect using that and see if the result is the same? (Would naturally need to open ports for UltraVNC also, think they are TCP/5900 and TCP/5901 as default)

The traffic was coming from seemingly random PCs destined for other seemingly random PCs in other VLANs/Subnets on TCP port 7680. Port Checker is an online tool which checks a remote computer or device accessibility from the Internet. It can be used to check open ports or Ping a Port on a remote server. When you ran netstat -ab, did you see the server listening at port 5900 on it's LAN IP address or on the loopback? For example, on my workstation when I run the netstat -ab command, I see it listening at 0.0.0.0:5900 and then I see TCP [::]:5900 also listed. I do NOT see it listening on the loopback address for port 5900.

TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered on port 5800 in the same order in which they were sent. Xorg 4403 root 9u IPv4 21108 TCP *:5900 (LISTEN) The process 4403 is the only X process running on my system, the same service that provides the console login. This is newly installed system, I have not undertaken any specific configuration of the X server or gdm.
21/tcp - In general you should not have this port open. You should switch to a secure FTP. If you must keep it open at least limit access to only those IP addresses that update content. 23/tcp - Telnet should no longer be used. Switch to SSH. 25/tcp - This means an email service could be running on this server.
tcp: vnc: VNC (Virtual Network Computing) - remote control programs, typically also use ports 5800+ and 5900+ for additional machines. Backdoor.Evivinc [Symantec-2004-042518-0520-99] trojan also uses this port. SG: 5800 : tcp: VNC remote desktop protocol - for use over HTTP (unofficial) Wikipedia: 5800 : tcp: vnc: SANS: 5800,5500,5900 : tcp TCP is one of the main protocols in TCP/IP networks. TCP is a connection-oriented protocol, it requires handshaking to set up end-to-end communications. Only when a connection is set up user's data can be sent bi-directionally over the connection.
