Internet Ports & Protocols - Introduction - This file contains all the assigned numbers from RFC 1060 for Internet Protocols and Service ports. There are also a few extras that weren't covered in RFC 1060. If an entry has a positive service port number, then it is an Internet Service and will list aliases, long name and also the protocol over which it runs. -1 If an entry has a positive protocol number, then it is an Internet Protocol and will list aliases and long name. -1 Compiled by Graeme Findlay {gfindlay@findlay.demon.co.uk} Last Updated 25 August 1999 If you find any errors or omissions, please e-mil me and I will update the file for general use. -1 IP 0 Internet Protocol -1 ICMP 1 Internet Control Message -1 IGMP 2 Internet Group Management -1 GGP 3 Gateway-to-Gateway -1 ST 5 Stream -1 TCP 6 Transmission Control -1 UCL 7 UCL -1 EGP 8 Exterior Gateway Protocol -1 IGP 9 any private interior gateway -1 BBN-RCC-MON 10 BBN RCC Monitoring -1 NVP-II 11 Network Voice Protocol -1 PUP 12 PARC Universal Packet Protocol -1 ARGUS 13 ARGUS -1 EMCON 14 EMCON -1 XNET 15 Cross Net Debugger -1 CHAOS 16 Chaos -1 UDP 17 User Datagram -1 MUX 18 Multiplexing -1 DCN-MEAS 19 DCN Measurement Subsystems -1 HMP 20 Host Monitoring -1 PRM 21 Packet Radio Measurement -1 XNS-IDP 22 XEROX NS IDP -1 TRUNK-1 23 Trunk-1 -1 TRUNK-2 24 Trunk-2 -1 LEAF-1 25 Leaf-1 -1 LEAF-2 26 Leaf-2 -1 RDP 27 Reliable Data Protocol -1 IRTP 28 Internet Reliable Transaction -1 ISO-TP4 29 ISO Transport Protocol Class 4 -1 NETBLT 30 Bulk Data Transfer Protocol -1 MFE-NSP 31 MFE Network Services Protocol -1 MERIT-INP 32 MERIT Internodal Protocol -1 SEP 33 Sequential Exchange Protocol -1 3PC 34 Third Party Connect Protocol -1 ANY HOST INTERNAL PROTOCOL 61 any host internal protocol -1 CFTP 62 CFTP -1 ALN 63 any local network -1 SAT-EXPAK 64 SATNET and Backroom EXPAK -1 RVD 66 MIT Remote Virtual Disk Protocol -1 IPPC 67 Internet Pluribus Packet Core -1 ADFS 68 any distributed file system -1 SAT-MON 69 SATNET Monitoring -1 VISA 70 VISA Protocol -1 IPCV 71 Internet Packet Core Utility -1 BR-SAT-MON 76 Backroom SATNET Monitoring -1 SUN-ND 77 SUN ND PROTOCOL-Temporary -1 WB-MON 78 WIDEBAND Monitoring -1 WB-EXPAK 79 WIDEBAND EXPAK -1 ISO-IP 80 ISO Internet Protocol -1 VMTP 81 VMTP -1 SECURE-VMTP 82 SECURE-VMTP -1 VINES 83 VINES -1 TTP 84 TTP -1 NSFNET-IGP 85 NSFNET-IGP -1 DGP 86 Dissimilar Gateway Protocol -1 TCF 87 TCF -1 IGRP 88 IGRP -1 OSPFIGP 89 OSPFIGP -1 SPRITE-RPC 90 Sprite RPC Protocol -1 LARP 91 Locus Address Resolution Protocol tcpmux 1 TCP Port Service Multiplexer tcp -1 rje 5 Remote Job Entry tcp -1 echo 7 tcp -1 echo 7 udp -1 discard 9 sink null tcp -1 discard 9 sink null udp -1 systat 11 Active Users users tcp -1 systat 11 Active Users users udp -1 daytime 13 tcp -1 daytime 13 udp -1 netstat 15 tcp -1 netstat 15 udp -1 qotd 17 Quote Of The Day quote tcp -1 qotd 17 Quote Of The Day quote udp -1 chargen 19 Character Generator ttytst source tcp -1 chargen 19 Character Generator ttytst source udp -1 ftp-data 20 File Transfer [Default Data] tcp -1 ftp 21 File Transfer Protocol [Control] tcp -1 telnet 23 Telnet tcp -1 smtp 25 Simple Mail Transfer Protocol mail tcp -1 nsw-fe 27 NSW User System FE tcp -1 msg-icp 29 MSG ICP tcp -1 msg-auth 31 MSG Authentication tcp -1 dsp 33 Display Support Protocol tcp -1 apps 35 any private printer server tcp -1 time 37 Time timserver tcp -1 time 37 Time timserver udp -1 rlp 39 Resource Location Protocol resource tcp -1 rlp 39 Resource Location Protocol resource udp -1 graphics 41 Graphics tcp -1 name 42 nameserver tcp -1 name 42 nameserver udp -1 whois 43 Whois -
