Webmin and Usermin with DirectAdmin

[zoney70]

I recently noticed Webmin and Usermin are installed on my DirectAdmin server. I presume this was used while installing my server?

I have several questions.

(1) Is it possible for me to use this from localhost on the server? My usage would be for doing stuff I would normally have to use the command line. (create users outside of DirectAdmin, various other stuff) What is the syntax fo accessing the panel? Can I make it inaccessible from the web-facing IPs?

I would use it by establishing a port forward tunnel under SSH. I use this technique now for ftp, smtp, and imap so don't know any reason I couldn't use it for http as well.

(2) I notice both webmin and usermin are logging some accesses almost daily. Mostly, they appear to be unsuccesful buffer overflow attacks, or unsuccessful attempts to post a cgi. What are the criteria for logging in these logs, as opposed to the http domain logs?

(3) Both error logs log 2 entries every time the VPS is restarted. These are:
[date] miniserv.pl started
[date] Perl module Authen::PAM needed for PAM is not installed : Can't locate Authen/PAM.pm in @INC (@INC contains: blah blah blah
BEGIN failed--compilation aborted at (eval 6) line 1.
Why is this happening?
