How SSH got port number 22
- tkanarsky 4y agoTL;DR: He asked nicely
- 1letterunixname 4y ago0. I wonder how many licenses ssh.com sells per year when competing with free OpenSSH (on OpenBSD), OpenSSH portable (derive from OpenSSH), and libssh2. 1. There's no mention ARP spoofing / TCP connection hijacking that can be performed against unauthenticated, plaintext protocols with L2-L3 dumb LANs that don't perform port authentication.
