Postfix Master Fatal Bind 0.0 0.0 Port 25 Address Already In Use
Unfortuantely it didn't quite solve the problem (see below for how). I followed the instructions and ran the following check, to which I received an encouraging response: $ dpkg -S `which sendmail` postfix: /usr/sbin/sendmail However when I started postfix again, I got the same error. As per Oli's contingency, I looked for the process that was hogging port 25 with the following: $ sudo netstat -pel | grep smtp tcp 0 0 localhost.localdom:smtp *:* LISTEN root 35704126 27626/sendmail: MTA But here's where it got confusing: I then looked for the process 27626 but was then told: dpkg-query: no path found matching pattern 27626 connections. I pulled up htop and was able to find the above PID associated with the following command: sendmail:MTA: accepting connections I then tried to kill the process with both killall sendmail and killall 27626 and kept getting no process found. The problem is (besides the obvious) I don't know how to interpret these findings. I scrubbed the server of sendmail, so I can only assume that postfix's own version of sendmail is hijacking the port? I don't even know if that makes sense. Anyway, if anyone could set me straight on this or at least give some interesting diagnostics questions, I'd appreciate it. In case it's useful, I'm using virtualmin on the server to manage a few different domains and am also running wordpress.

Errors in Webserver Stress Tool For high traffic scenarios this message shows a problem on the workstation running Webserver Stress Tool. The IP stack can't create additional outgoing TCP/IP connections because it runs out of available socket numbers for the IP address(es) that you have configured in Webstress. This error occurs when your workstation cannot allocate new sockets. On Windows the default limitation is 5000 - 1024 open sockets (5000 is the default max user port setting and the first 1024 ports are reserved). You can increase the default maximum socket value in the registry: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Tcpip/Parameters and add or modify the MaxUserPort value. See Also Microsoft article: "When you try to connect from TCP ports greater than 5000 you receive the error 'WSAENOBUFS (10055)'" The Cable Guy article: "Windows TCP/IP Ephemeral, Reserved, and Blocked Port Behavior" Add comment Created on Feb 24, 2010 9:10:15 AM by Daniel Zobel [Paessler Support] Last change on Sep 1, 2015 8:07:43 AM by Erh
