SSH is the most favorate way to connect to any Linux\/ cPanel server when something goes wrong, and geeks still use it even for many tasks that a novice will do through the WHM interface. <\/p>\n

Have you ever noticed 1000s of invalid login attempts when you log in to SSH? On one of the servers we manage, it looked like this.<\/p>\n

\n
\r\nThere were 18261 failed login attempts since the last successful login.\r\nLast login: Tue Jan 26 01:28:48 2021 from xxx.xxx.xxx.xxx\r\n\r\n  CentOS Linux 7 (Core)\r\n\r\nLinux sub.server-host.net 4.19-ovh-xxxx-std-ipv6-64 #1179808 SMP Mon Mar 30 07:31:39 UTC 2020 x86_64 x86_64 x86_64 GNU\/Linux\r\n\r\n\r\n  Server        : 19182\r\n  IPv4          : xx.xxx.xxx.xx\r\n  IPv6          : xxxx:xxxx:xxx:xxxx::\r\n  Hostname      : sub.server-host.net\r\n<\/pre>\n<\/div>\n
<\/div>\n
On windows, we use Putty ssh client, which you can download from putty website  putty.org<\/a>
\nThe best way to tackle these invalid attempts is to change the default ssh port, 22, to a custom one. <\/p>\n
\n
How To change the SSH port of your server.<\/h3>\n
    \n
  1. Login to your server with your favorite SSH client (we use putty)<\/li>\n
  2. If you use a firewall (for example, CSF Config Server Security & Firewall, the best free firewall for cPanel servers), open the port in the firewall before you make a change.<\/li>\n
  3. Edit config file for SSH\n
    \n
     nano \/etc\/ssh\/sshd_config<\/pre>\n<\/div>\n<\/li>\n
  4. Find the line with #port 22 and (1) remove # (2) change the number. Chose a random number, or one that is easy to remember for you between 1024 to 65535. All the port numbers from 0 to 1023 are designated to famous privileged service.\n
    \n
    Port 9467<\/pre>\n<\/div>\n<\/li>\n
  5. Resetart SSH Service\n
    \n
    systemctl restart sshd.service<\/pre>\n<\/div>\n<\/li>\n
  6. Important Do not close the current SSH session yet. Logon to the server from the new putty session on the new port to ensure new arrangements are working.<\/li>\n<\/ol>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
