Sendmail refuses to listen on public interface
in [Sendmail]
|
From: mloiterman on 21 Sep 2005 22:48 Using: FreeBSD 5.4-RELEASE Sendmail 8.13.3 I'm trying to setup my mail server, but sendmail is only listening on the local interface. I know this because: 1. # grep sendmail_submit_enable /etc/defaults/rc.conf sendmail_submit_enable="YES" # Start a localhost-only MTA for mail submission 2. # netstat -an | grep 25 tcp4 0 0 127.0.0.1.25 *.* LISTEN 3. I can do: # telnet localhost 25 And sendmail answers correctly. But, if, from another machine within my network: # telnet 192.168.1.22 25 I get a connection refused. Additionally, the sendmail logs show nothing of the connection attempt. How can I get it to listen on all interfaces? When I put any of the following combinations in rc.conf: sendmail_enable="YES" sendmail_submit_enable="YES" sendmail_enable="YES" sendmail_submit_enable="NO" sendmail_enable="YES" I get the following errors in my messages.log when I start sendmail: Sep 20 11:09:40 eisenhower sm-mta[2461]: starting daemon (8.13.3): SMTP+queueing(a)00:30:00 Sep 20 11:09:40 eisenhower sm-mta[2461]: NOQUEUE: SYSERR(root): opendaemonsocket: daemon MTA: cannot bind: Address already in use Sep 20 11:09:40 eisenhower sm-mta[2461]: daemon MTA: problem creating SMTP socket Sep 20 11:09:40 eisenhower sm-msp-queue[2464]: starting daemon (8.13.3): queueing(a)00:30:00 Sep 20 11:09:45 eisenhower sm-mta[2461]: NOQUEUE: SYSERR(root): opendaemonsocket: daemon MTA: cannot bind: Address already in use Sep 20 11:09:45 eisenhower sm-mta[2461]: daemon MTA: problem creating SMTP socket Sep 20 11:09:50 eisenhower sm-mta[2461]: NOQUEUE: SYSERR(root): opendaemonsocket: daemon MTA: cannot bind: Address already in use Sep 20 11:09:50 eisenhower sm-mta[2461]: daemon MTA: problem creating SMTP socket Sep 20 11:09:55 eisenhower sm-mta[2461]: NOQUEUE: SYSERR(root): opendaemonsocket: daemon MTA: cannot bind: Address already in use Sep 20 11:09:55 eisenhower sm-mta[2461]: daemon MTA: problem creating SMTP socket Sep 20 11:10:00 eisenhower sm-mta[2461]: NOQUEUE: SYSERR(root): opendaemonsocket: daemon MTA: cannot bind: Address already in use Sep 20 11:10:00 eisenhower sm-mta[2461]: daemon MTA: problem creating SMTP socket Here's are more troubleshooting steps I did: 1. Killed all sendmail processes # killall -9 sendmail # 2. Wiped out all custom sendmail config files and created fresh clean standard ones. # rm hostname.* # make all 2. Listed everything before starting up sendmail # netstat -naf inet Active Internet connections (including servers) Proto Recv-Q Send-Q Local Address Foreign Address (state) tcp4 0 0 192.168.1.22.22 192.168.1.3.4154 ESTABLISHED tcp4 0 0 *.993 *.* LISTEN tcp4 0 0 *.143 *.* LISTEN tcp4 0 0 *.995 *.* LISTEN tcp4 0 0 *.110 *.* LISTEN tcp4 0 0 *.139 *.* LISTEN tcp4 0 0 127.0.0.1.783 *.* LISTEN tcp4 0 0 *.3306 *.* LISTEN tcp46 0 0 *.80 *.* LISTEN tcp4 0 0 *.22 *.* LISTEN udp4 0 0 192.168.1.22.138 *.* udp4 0 0 192.168.1.22.137 *.* udp4 0 0 *.138 *.* udp4 0 0 *.137 *.* udp4 0 0 127.0.0.1.123 *.* udp4 0 0 192.168.1.22.123 *.* udp4 0 0 *.123 *.* udp4 0 0 *.514 *.* I don't see anything that should conflict. Do you? 3. Started sendmail # cd /etc/mail # make start 4.

(Time [PID]) Thanks for pointing out the obvious. Yes, they're the same errors.

I don't have any missing files.

I thought of that, but that line doesn't exist in my .mc file. Thanks though. |
