If you don't have login access to the server, you can find the SSH port using nmap's "version scan" feature:. nmap -sV -p- The -sV option means "version scan", and -p-means "scan all ports". If you've got a good connection and are sure you won't be upsetting someone's firewall or IDS, you can add -T5 for "scan as fast as possible".

Does SSH use TCP or UDP? - Quora SSH uses a TCP port when you connect to it. TCP is a much more reliable connection than UDP because it goes through a 3 way handshake known as SYN SYN-ACK ACK which synchronizes and acknowledges your connection, thus guaranteeing delivery. It is a SSH and telnet port open - Cisco Community If you are trying to CONNECT to a router using SSH or Telnet, you want to use the "transport input" command to indicate what protocols may be used to connect to the router. Example: line vty 0 5 !(or whatever range you like)

Mar 07, 2008 · SSH: As already noted, SSH is an encrypted secure remote login protocol, which uses port 22 by default. Telnet: Like rlogin, Telnet (telecommunication network) is an unencrypted remote login

Changing the port ssh uses. You can easily change the port ssh uses. By default it on port 22, so everyone will try it. Change the port using: bone$ sudo vi /etc/ssh/sshd_config. Scroll to around line 13 and you'll see: #Port 22. Remove the # and change the 22 to something greater than 1000, say 1022. Then bone$ sudo systemctl restart sshd

FTP/FTPS, SFTP, and FTP over SSH all have one thing in common: they’re made primarily for file transferring. FTP is the most basic version of this idea, and operates on an insecure network, while FTPS is a secure version of the same protocol. FTP over SSH uses an SSH tunnel between the FTP client and the server.

Port 22 (tcp/udp) :: SpeedGuide ssh: The Secure Shell (SSH) Protocol Old verson of pcAnywhere uses port 22/udp (no relation to ssh and port 22/tcp). The real pcAnywhere port is 5632. The value 0x0016 (hex) is 22 decimal; the value of 0x1600 (hex) is 5632 decimal. Some say that pcAnywhere had a byte-swapping bug that led to its incorrect use of port 22. SG: 22 : tcp,sctp: SSH tcp - How to connect ssh from a specified port? - Unix A simple solution for this if you are port forwarding through your router is to set the inbound port to whatever you want and the local port to 22. Your machine will still be taking ssh connection on 22 like normal but to actually connect from outside your network you would use your inbound port.
