For security, we use a non-standard (other than 22) for all of our in-house servers. We got tired of brute-force attacks filling our logs.
However, I have been hesitant to change our primary Virtualmin server for fear of unintended consequences.
We don't have any non-admin SSH users ATM, and if we did, they'd be smart enough to use a non-standard port.
Is there a problem with changing SSH to a non-standard port for enhanced security?
BTW, I already changed a second Virtualmin GPL server that we use for limited functions (backup MX, backup DNS, etc.), and I haven't had any obvious fallout.
Thanks in advance,
