The functionality of the 'who' command on my server has changed. Up until about 6 weeks ago it worked the way it should. Now when I issue 'who' I do not see the other logged in users. I only see the user I am logged in as.
This server is a virtual server in hosted environment. So, I not necessarily informed about all the server admin activity that goes on.
I inquired with the appropriate tech support, but was blown off with a response that suggested our version of Linux (a fairly current versions of RHEL) might not support the 'who' command. I say hogwash. I am absolutely certain that I have used the command successfully in the not too distant past and certainly in our RHEL environment.
Do you have any suggestions for what might cause this change?
Many thanks,
Shellie

I welcome your comments. However... I am puzzled by many people who say "Please send me the Linux tutorial." This website *is* your Linux Tutorial! Read everything here, learn all you can, ask questions if you like. But
don't ask me to send what you already have. :-) NO SPAM! If you post garbage, it will be deleted, and you will be banned.
