Description


  • After a new installation, no service is listening on 110, 995, 143, 993. If we look in the nginx.log, we will see similar errors as above:
2017/05/22 11:28:23 [debug] 2232#0: bind() 0.0.0.0:143 #6 
2017/05/22 11:28:23 [emerg] 2232#0: bind() to 0.0.0.0:143 failed (98: Address already in use)

  • Checking /etc/hosts revealed no errors.
  • There was no output running those commands:
fuser 143/tcp 
fuser 110/tcp 
fuser 99/tcp 
  • If we run netstat, there is nothing LISTENING on these ports.

Resolution


A service called portreserve was running, and it was listening on the UDP ports 110 143 995 993.

Stopping/disabling it fixed the issue.

After thoughts


  • When checking the service on RHEL 6, it appeared to be installed but not running:
$ fuser 993/tcp 
993/tcp: 4132 4133 4134 4135 
$ fuser 993/udp 
$ netstat -putna |grep 993 
(Not all processes could be identified, non-owned process info 
will not be shown, you would have to be root to see it all.) 
tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN 4132/nginx 
tcp 0 0 0.0.0.0:7993 0.0.0.0:* LISTEN - 

Nothing pointing to 993/udp, zimbra is using 993/tcp.

  • Checking if the service is started:
$ service --status-all | grep -i portreserve 

portreserve is stopped 
  • However, chkconfig is showing:
chkconfig --list 
portreserve 0:off 1:off 2:on 3:on 4:on 5:on 6:off 

We should make sure these are all off If the issue is present.
