TCP 259

Looking for information on Protocol TCP 259? This page will attempt to provide you with as much port information as possible on TCP Port 259.

TCP Port 259 may use a defined protocol to communicate depending on the application. A protocol is a set of formalized rules that explains how data is communicated over a network. Think of it as the language spoken between computers to help them communicate more efficiently.

Protocol HTTP for example defines the format for communication between internet browsers and web sites. Another example is the IMAP protocol that defines the communication between IMAP email servers and clients or finally, the SSL protocol which states the format to use for encrypted communications.

PORT 259 – Information

• Port Number: 259
• TCP / UDP: TCP
• Delivery: Yes
• Protocol / Name: fw1-auth,esro-gen
• Port Description: Firewall-1 RDP (CheckPoint). FW-1’s Reliable Datagram Protocol, used by FW-1’s to agree on VPN crypto parameters. RDP provides out-of-band sessions, plus: Negotiation of session keys. – Agreement on session crypto algorithm (DES or FWZ-1). – Decision on if MD5 data integrity will be used. – Ensures dropped UDP pkts are retransmitted. FW-1 Ports: tcp 256, tcp/udp 259, udp 500, tcp 900.
• Virus / Trojan: No

Side note: TCP port 259 uses the Transmission Control Protocol. 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 259 in the same order in which they were sent. Guaranteed communication over port 259 is the key difference between TCP and UDP. UDP port 259 would not have guaranteed communication in the same way as TCP.

Because protocol TCP port 259 was flagged as a virus (colored red) does not mean that a virus is using port 259, but that a Trojan or Virus has used this port in the past to communicate.
