There is a Howto file on firewalls, if you have a slackware linux system,
and did install the howto files, it will be
/usr/doc/faq/howto/Firewall-HOWTO

If not you can find it on most major Linux archives.

: Here is my problem:
: The group that set up this ISPs server placed a firewall which denies telnet

: message that says something like "Your host is not allowed to telnet to this 
: host.  Connection Closed."  Some users, those specified in some configuration 
: file somewhere I assume, are allowed telnet into the server.  As best as I can 
: guess, the firewall goes to the system logs, looks up the IP of the user that 
: is trying to telnet, and checks whether that specific user is allowed to 
: telnet.

: I need to:
: 1) Allow permission to my username to allow telnet access when I dial directly 
: to this server.
: 2) If possible, specify certain usernames from other servers to allow them to 
: access by telnet (I live 40 miles away and would like not to have to dial 
: long-distance.)
: 3) Still limit most of the ISPs customers from having telnet access for 
: security reasons.

: Now, nobody that is at the ISP knows very much about firewalls, including me.  
: But, if someone could give me instructions on what files to edit, I can go 
: directly to the sever, access as root, and make the changes.

: Thanks a lot.!!

: Merry Christmas!!

: P.S.  Please reply by email, I may not check this group often.
