    Gabriel,

    Thank you so very much for the excellent tutorial. I am assuming that you currently certified as RHCSA? I am currently preparing to go and present the text so these tutorials you have been created are excellent for practice and preparation. Gracias de nuevo!

    • @Jairusan,
      I appreciate your taking the time to comment on this post and for your kind words about my work. To answer your question – no, I am not certified as RHCSA. More of a logistics issue than anything else – I live ~450 miles from the nearest testing center. Hopefully in the future.

    Open the /etc/ssh/sshd.conf file and change the Port=22 entry to Port=
    Restart SSh to see your new SSh port.
    Make sure your firewalls are also updated for incoming requests to this new port.
