Open Ports in Karaf
Hi, I am trying to figure out what ports Karaf opens up. I was able to get most of them (ssh, jmx rmi, etc) except a few. Everytime Karaf starts up (v. 2.1.0) it opens up two randomly assigned ports in the high numbers. For example: 3:tcp4 0 0 127.0.0.1.57165*.*LISTEN 4:tcp46 0 0 *.57164*.*LISTEN If I turn off the DisableAttachMechanism flag so that jconsole cannot connect to karaf, the bottom one is gone, but the top one remains: 3:tcp4 0 0 127.0.0.1.57168*.*LISTEN (Notice, they are different numbers because they are randomly assigned) Does anyone know why this port is opened, and how to close it?

Rosh, Could you please let us know how you identified that as an issue? I'd like to see if I can replicate this with Karaf 2.0 and 1.6. v/r, Mike Van - Original Message - From: Roshan A.

RE: Open Ports in Karaf
First I ran the command netstat -an | grep LISTEN on my Terminal before starting the container and got the list of open ports. Then after starting the container, I reran the command and did a diff and that's how I found the alx open ports. I could account for all except the two I listed below. Another thing I did was to clear out the whole etc/startup.properties file, so that only the core felix/karaf would run and not load any bundles. I found that those two ports are the only ones open. The DisableAttachMechanism JVM flag disabled one, but I can't figure out what the other local one is for.

Re: Open Ports in Karaf
Hello Roshan, looks like an issue we figured out some weeks ago. I discussed this in [1] and opened an issue for it [2]. It's fixed in 2.2.0 and it's easy to fix it in previous versions... Hope this helps. [1] http://servicemix.396122.n5.nabble.com/DISCUSS-changing-the-default-JMX-service-uri-td3229446.html#a3229446 [2] https://issues.apache.org/jira/browse/KARAF-253 Cheers, Christian
Re: Open Ports in Karaf
One of them must be the tcp port opened to stop karaf as in tomcat (i.e. a free random port is opened and bound to the localhost only and written to the data/port file). It can be configured using the karaf.shutdown.port property (the default value of 0 means a random port). Not sure about the other one though. On Tue, Nov 9, 2010 at 17:56, Roshan A.
