blocking telnet to selected IPs?

[Dave Vose]

I've searched the archives without success, however I'm quite sure the 
subject has been covered here. 

We may be forced to discontinue email access in the library but we'd like to
retain telnet capability for access to other OPACs, etc. Is there a way 
to block telnet access to selected IP addresses in Netscape 3.x and 
4.x?

We have two platforms: UNIX running Solaris and PCs running NT. We've
locked our machines down pretty tight and would like to kill telnet access
to the campus mail server without buying filtering software like Kiosk,
etc. 

Thanks
