hydrogen 100% network usage

[Mark Falcey]

I have recently noticed that when hydrogen starts it tries to connect to the internet and keeps trying continuously the entire time it is running. As a result other applications such as firefox, apt, synaptic have great difficulty connecting to the internet and apt and synaptic are unable to download updates and other packages.

The only reason I noticed this is that I can now see my router and dsl modem lights. I start hydrogen and they flash like crazy. I stop hydrogen and they stop. Generally when using hydrogen other internet using applications are not used and I could not see my router/modem lights so this probably went unnoticed for a long time.

There is no way to stop this behavior other than closing hydrogen.
I suspect there is some internet address that cannot be found coded into a continuous loop in the source somewhere. If that is the case this could be a serious security vulnerability.

I have confirmed this behavior in hydrogen standard repository packages Ubuntustudio amd64 in Hardy, Intrepid and Jaunty.

If you need any more information/help, please let me know.

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Hello Mark,

Thanks for taking the time to report this bug. I'm running hydrogen on Intrepid and I'm unable to reproduce the behavior you're describing above. Could you be more specific about the things you're doing in hydrogen when you notice this behavior?

Also, what is the output of

netstat -lapunte | grep hydrogen

run in a terminal when you have hydrogen running and you experience the behavior you describe above?

Hi Nicolas,
Thank you for the attention. This is very perplexing for me.

All I need to do is start Jack, open Hydrogen and this happens. System monitor reports continuous sending at 40-60k and receiving at 25-60k. As soon as I close hydrogen network activity drops to zero. This happens every time I start hydrogen in Hardy, intrepid, and Jaunty. I have UbuntuStudio-audio package installed over Ubuntu amd64 on all three.

This is when I am using Intrepid
I am using Hydrogen 0.9.3-5.1ubuntu1

netstat -lapunte | grep hydrogen

udp 0 0,0,0,0,0:38932 0,0,0,0:k
