Vuze open udp port

[coconope]

I had a total config crash and reinstalled 5300 > 5400 > 5401_b01 > 5401_b02
But now I see that Vuze open some dynamic udp ports (both tcpv4 & tcpv6) every time I start/restart!
The ports changes for every start/restart!
(seen this in both b01 & b02)

I have not installed any new plugins since the crash. (see pict for used plugins)
(I have failed to rule out wich one of the plugins that could be responsible for these ports!)

Running Vuze  behind a firewall/NAT net and need to redirect properly.

This is how netstat looks like:

Hmm, that could be some new coded added in 5400 (I assume you saw this behaviour prior to 5401_B01 as nothing really changed there - if I am right this code was added a few months ago) that tries to grab peers from the DHT - it is a backup mechanism and the assumption was that any NAT devices general support for UDP temporary firewall 'holes' would be sufficient (unsolicited incoming UDP packets do not need to route).

You should only see one of these active though, not sure why you are seeing multiple ports - does the list continue to grow over time? 

[coconope]

yes....

"I assume you saw this behaviour prior to 5401_B01"..........no, but it could have been soo!

I reverted back to 5301_b50 and no mIDHT.....voila! no "extra" ports unsed. (still using vuze v5000.exe as loader)

And I saw that the setting for mIDHT plugin refused to use the port selected, tons of tons firewall entries on default port 49001.
when i switched back to default I guess that i will have to live with all "channel" packets in the flow until they forget me?
 
Man! Didnt the creators of imDHT invent any way of removing users from the pool? After 12h I still recieve around five calls every minute!!
 

 

 

 

[coconope]

testing 5401_b03 + miDHT

better but.....

Vuze open a listen port bound to localhost for something (think port opens right away early in the startup process)
and do not reuse that port eg reopen a new port all the time (not that good)

the six first ports are ok (vuze componet traffic?) but the last use up ports quite fast...
guess this is miDHT?

 

 

[parg]

If they're TCP ports in a 'TIME_WAIT' then that means the connection has been closed by your computer and the network is waiting for a period of time to receive any stray packets that might arrive and cause confusion if the port is immediately reused.

Best bet would be that they are peer connections?

[coconope]

no, they are not...

look at this line:
  TCP    127.0.0.1:54341        0.0.0.0:0              LISTENING       3628

see the port number? all the time_wait connections was from above connection.
TCP    127.0.0.1:54341        127.0.0.1:36419        TIME_WAIT       0

also the other way:  TCP    127.0.0.1:37107        127.0.0.1:54341        TIME_WAIT       0

can this be a pair like:
  TCP    127.0.0.1:54339        127.0.0.1:54340        ESTABLISHED     3628
  TCP    127.0.0.1:54340        127.0.0.1:54339        ESTABLISHED     3628
gone broken?

[coconope]

5401_b03 w/o mlDHT is fine, no localhost interconnect trashing...
