Sorry, I don't understand what you > wonder about and what you tried to configure so far. > > Alexander Hi Alexander, ...sorry if I confused you; let me see if I can clarify. rivers-bend.com is my domain w/a public ip of 209.205.179.141 This box right here is rbmain1 [10.0.0.10] running on fc2 which is fully updated. It's running dns, sendmail 8.12.11-4.6, dovecot, and other things w/no problems. the box w/problems is rbmain2 [10.0.0.12] running on fc3 w/no updating yet. My intentions are to mirror 10.0.0.10 w/10.0.0.12. After it's all set up, I'll probably use rsync or something to sync up the 2 machines and if/when 10.0.0.10 ever goes down, just run a script on 10.0.0.12 and it will take over. Now, while setting 10.0.0.12 up, presently I shut down 10.0.0.10 because I don't have scripts in place yet. While 10.0.0.10 is down, dns in 10.0.0.12 takes over and works fine. Now the problem: using evolution, I can mail to myself i.e. from: rado@xxxxxxxxxxxxxxx to:rivers-bend.com and it will pop fine. I can send mail out to my hotmail acct: radopowder@xxxxxxxxxxx, and it is received...I reply from hotmail to rado@xxxxxxxxxxxxxxx, and it never comes. Mind you this is in the fc3 sys, [10.0.0.12]. ok, let's shut down 10.0.0.12 now. bring up 10.0.0.10... that's this box. the email reply that I was trying to receive in 10.0.0.12 shows up here in 10.0.0.10. Somehow mail is being stopped from being received on 10.0.0.12. here's a list of my open ports: [root@rbmain2 ~]# nmap -sT rbmain2 Starting nmap 3.70 ( http://www.insecure.org/nmap/ ) at 2005-03-09 08:05 CST Interesting ports on rbmain2.rivers-bend.com (10.0.0.12): (The 1654 ports scanned but not shown below are in state: closed) PORT STATE SERVICE 22/tcp open ssh 25/tcp open smtp 53/tcp open domain 110/tcp open pop3 111/tcp open rpcbind 113/tcp open auth Nmap run completed -- 1 IP address (1 host up) scanned in 0.283 seconds Don't forget, Alexander, 10.0.0.12 is only up while I'm working on it. when I need to check email like this msg list, I have to shut down 10.0.0.12 and bring up this machine, 10.0.0.10. I also monitor my hotmail acct. regularly radopowder@xxxxxxxxxxx which could be used for testing communication. That's always up. Ok, I hope this clears it up. Alexander, if you want to see logs or testing please just ask. thx, John Rose -- Trust Everyone. Just make sure you brand your cattle.
