hi all, this is kind of trickey, so i'll try to be as clear as i can. i have a RH 6.2 machine at work, functioning as a mail-relay to an exchange server sitting in the local LAN, with NAT address. the linux machine is in a DMZ, with 1 nic, real ip. everything worked wonderfull for more then 2 years, until last week, when someone did a hard reset to that machine. as for now, users that try to telnet this machine or get mail from it (using ms outlook) are getting stuck in the autontication. the mail client gets stuck on "verifying username and password" for 1-2 minuetes, and then gives up with a connection timeout. i forgot to mention that some users use this machine as a pop3 server, and others use the exchange (all mail messages are forwarded to teh exchange, except for users that have "CL username" in sendmail.conf . from the outside, all services work just fine. this is not a firewall problem, since i unloaded the policy, tried and got nothing as well. for some reason, i cannot get to authonticate (as pop3 or telnet) from the internal network. there is nothing preventing me to access in hosts.deny . i am able to ping that machine from the inside, but thats about all i can do. nothing more. i did not change anything, or even touched that machine since the last time it worked, so there is no way that i did something wrong in any of the configuration files. the only change that was "made" was that hard reset. (boy, is that guy gonna get it) ;)
