    Please fill in any relevant information that applies to you:
    • CentOS Version: i.e. CentOS 7 64bit ?
    • Centmin Mod Version Installed: i.e. 123.09beta01
    • PHP Version Installed: i.e. 7.2.11
    1. New beta01 install.
    2. cmdir, centmin, option 16
    3. Asks for default port enter 22
    4. Asks for a new port 9348. Set the port to a port which is already used by the system (9348). Restart sshd.
    5. Logout
    6. SSH login with new port (9348). SSH fails because the script didn't un-comment the line in the sshd_config for obvious reasons (port in use). Have to use port 22.
    7. cmdir, centmin, option 16
    8. Asks for existing port. (22 or 9348) Says 9348 is used by the system but is the current set port. Need to enter a port which isn't in use "9808". Restart sshd.
    9. Logout
    10. SSH login with new port (9808). SSH fails because the script didn't un-comment the line in the sshd_config. Have to use port 22.
    I had to go into the sshd_config file and un-comment the "Port 9808" so it became active. Otherwise, it keeps failing when connecting leading to someone thinking they entered the wrong port, in the config file, when in actuality it's still port 22 because the Port XXX in the file is still commented.

    I only did this once. Didn't have time to test it on other machines. Nevertheless, wanted to report it.

    strange i can't see how that is happening unless your /etc/ssh/sshd_config has a different format for the port entry

    centmin mod is looking for entry like
    Code (Text):
    #Port 22

    to uncomment via sed replacement. If you entry has a spacing format different
    i.e.
    Code (Text):
    #Port    22

    oh missed that part - then it's normal, if you set to a new sshd port that is already in use, centmin mod will skip changing sshd port in /etc/ssh/sshd_config

    I guess this is where the bug is then

    FYI, just updated 123.09beta01 with a possible fix for this :)

    cmupdate command will up date your local centmin mod code
    Code (Text):
    cmupdate

    Thanks! It was funny because for about 10 minutes I was guessing ports until I decided to try 22.
