TCP 222
Synopsis
- TCP/222 is registered by IANA for rsh-spx (Berkeley rsh over IPX/SPX), historically seen in Novell NetWare environments.
- In modern practice, SSH servers (e.g., OpenSSH, Dropbear) are often reconfigured to listen on TCP/222 as an alternative to the default port 22 to reduce noise or avoid conflicts.
- Because SSH is frequently run on 222, attackers and botnets commonly scan and attempt brute-force logins on this port, a pattern widely observed by honeypots.
- Beyond these, no widely standardized or common default services are known to use TCP/222 today.
