Greetings, I am trying to set up a subnet with different sets of trusted hosts, i.e., the trusted hosts lists are different for the various groups allowing us to decide which machines have access to other machines via these trusted hosts lists. For example: @trusted-A: host1 host2 host3 @trusted-B: host4 host5 host6 @trusted-C: host7 host8 host9 So I can put +trusted-A and +trusted-B on another host without givinf hosts 7-9 access. The problem I'm encountering is that, having never admin'd a Linux network up until about three weeks ago and thus never worked with PAM, is that I can only find documentation for setting up trusted hosts when there is only one trusted host list from NIS (meaning the entire all-or-nothing trusted hosts map), not separate and independent maps. So I either have to abandon my multiple trusted hosts format and create the hosts.equiv files by hand/scripts (yechh!), or have all my hosts be trusted via PAM (double-yechh, and security dangerous, too!). My sincere apologies if this has been asked before, but I'm kinda in a hurry to get this accomplished and have exhausted the usual sources (and many-a-friend's knowledge). Is there any documentation on-line, or can someone forward me some clues on the setting up of PAM's files for r* commands for the multiple trusted host maps? Or even a way to bypass PAM and use the old somewhat-reliable authentication of UNIX days gone by? Thanks in advance!!! ....k -- *-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-* Kevin Freels, Systems Administrator 415/553.8000 (w) Wild Brain 415/850.3273 (c)
