Re: [platform-help-dev] multiple ports opening at eclipse web infocenter start



Help system uses one port for everything (serving help and interprocess
communication).  I have not seen any other port opened by embedded Tomcat
either.  You can pass -host option when launching infocenter, it will
additionally narrow down set of interfaces that Tomcat is listening on.

Browsers may use ports for their interprocess communication, but it is
outside of help system.   I would sugest posting a question on some Mozilla
forum.  If you are running infocenter, why are you launching a browser on
the same machine?

I did that. There is no processes attached to port 33229. Though the ports
momentarily after I started up my browser had Mozilla and/or java processes
(I assume it may be the plugin) associated with them. Then after a few
minutes it no longer had any processes associated with it. The additional
ports also disappear after there is not activity in the browser (I only
checked a half hour later). I guess there is not harm as it seems to grab
just free ports. My question is this to be expected. We had some users ask
about the additional ports being in use.

Thanks.

Julia

Try
lsof -i:32769
to find out the process that is listening on the other port.

Hi,

We are using Eclipse web infocenter specified to use a particular port
(8423). And when we start Eclipse and point the browser to the Eclipse
infocenter, we see multiple ports opened. For example, we see  this under
netstat -a

Proto Rec-Q Send-Q Local Address          Foreign Address State
tcp   0     0     *:8423                  *.*         LISTEN
tcp   0     0     hostname:32769    *:*         LISTEN

tcp   0     0     hostname:33229    hostname:8423     ESTABLISHED
tcp   0     0     hostname:33226    hostname:8423     TIME_WAIT
tcp   0     0     hostname:33225    hostname:8423     TIME_WAIT
tcp   0     0     hostname:8423           hostname:33228    TIME_WAIT
tcp   0     0     hostname:8423           hostname:33229    ESTABLISHED
udp   0     0     *:32768                 *:*

Is this caused by Tomcat Plugin?

Appreciated you response back. Thanks alot.
