I installed virtualmin on my server. It works fine at frond-end, but when I ssh and type virtualmin help, we get the message
-bash: virtualmin: command not found
Please tell me where is a possible problem?
It sounds like /usr/sbin may not be in your path.
Try typing out the full path to the command, I suspect that will do the trick:
If you're logging into a non-root account (which I assume to be the case, since every distro I know of includes /usr/sbin in the path for root), you'll also need to use sudo. The virtualmin command currently requires root to operate.
