Want to change the ssh port for ssh? Here is a good tutorial.
\n(Note: If you are making these changes – ssh to the server and keep the terminal open as you make the changes. Test with a new terminal. This way if something is amiss – you are not locked out.)<\/p>\n
Edit \/etc\/ssh\/sshd_config, enter:<\/p>\n
\n# vi \/etc\/ssh\/sshd_config\n<\/pre>\nNote:
\nThe strategy used for options in the default sshd_config shipped with OpenSSH is to specify options with their default value where possible, but leave them commented. Uncommented options change a default value.<\/p>\nUncomment the following and edit to set the port to 10221:<\/p>\n
\nPort 10221\n<\/pre>\nListenAddress option<\/p>\n
Note: If you have multiple IP address on the server, add you IP addresses.<\/p>\n
ListenAddress as follows :<\/p>\n
\n## bind sshd to two ip address on a non-standard port ##\nListenAddress 192.168.1.5:10221\nListenAddress 203.1.2.3:10221\n<\/pre>\nSave and close the file.<\/p>\n
Before you restart or reload sshd server. You need to update SELinux configuration or Firewall settings (iptables).<\/p>\n
You also need to update firewall settings so that users can login using TCP # 10221. Edit, <\/p>\n
\n\/etc\/sysconfig\/iptables and open sshd port 10221:\n# vi \/etc\/sysconfig\/iptables\n<\/pre>\nEdit\/append as follows:<\/p>\n
\n## delete or comment out port 22 line ##\n## -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT\n## open port 22\n-A INPUT -m state --state NEW -m tcp -p tcp --dport 10221 -j ACCEPT\n<\/pre>\nSave and close the file. If you are using IPv6, edit \/etc\/sysconfig\/ip6tables file too. Temporally, stop the firewall so that you will not loose the connectivity to the server:<\/p>\n
\n# service iptables stop\n# service ip6tables stop\n<\/pre>\nRestart sshd on a CentOS <\/p>\n
\n# service sshd restart\n<\/pre>\nVerify new port settings with the following netstat command:<\/p>\n
\n# netstat -tulpn | grep sshd\n<\/pre>\nFinally, start the firewall:<\/p>\n
\n# service iptables start\n## IPv6 ##\n# service ip6tables start\n<\/pre>\nNow, login with a different terminal to check the settings.<\/p>\n","protected":false},"excerpt":{"rendered":"
