Socket bind failed

[Guy deLyonesse]

I know, seems simple, right?

If I run

netstat -aon | findstr 0.0:8443

I get no output. Good. So 8443 is NOT in use by any app.

So I start Tomcat.

And run

netstat -aon | findstr 0.0:8443

again and get this output:

TCP 0.0.0.0:8443 0.0.0.0:0 LISTENING 3608

My webapp times out when I try and run it.

So it seems like Tomcat is managing to listen on port 8443 but isn't actually binding it, so it's broken internally and times out when I do a request against it.

This is Windows 7 and Tomcat 6.

Any thoughts?

[Rob Spoor]

Also try ports 8080, 8005 and 8009. Tomcat uses several ports by default: 8080 for HTTP requests, 8443 for HTTPS requests, 8005 for shutting down and 8009 for AJP - for allowing other browsers like Apache HTTPD and IIS to redirect requests to Tomcat.

[Guy deLyonesse]

Yeah those ports are all being successfully bound when Tomcat starts. It's only 8443 that has a problem.

[Tim Holloway]

If 8443 is available when Tomcat is down, and Tomcat says "only 1 user allowed", I'd look at the server.xml to see if 8443 is defined in more than one connector, causing Tomcat to attempt to set up 2 different listeners on port 8443.

8443 can be tricky, since in addition to specifying it as a primary (https) listening port, a number of other connectors get told to send secure requests to 8443. So not every reference to 8443 is a listener definition. It's only multiple listeners that you have to worry about.

[Guy deLyonesse]

Yeah I was looking at that too. In the fresh Tomcat install the secure Connector is actually commented out, and uncommenting it is the only change I made to the file. Here it is:
