Background CB client in linux?

[magnav0x]

Hey guys have you had any problems running the linux cb agent in the background? I try executing:

nohup ./cbspn &

And it terminates rather quickly.

I run all of mine in background.

Don't bother with nohup, it's not really needed.

I'm not sure why but even when I run it in the background without nohup the client doesn't seem to do any work:

./cbspn > cb1.log &

but if I run it normal in a terminal

./cbspn

it will actualy get work and do it. If I load it in the background it will show with 'ps' but it never grabs any work.

Do they somehow get different nice levels ?

Perhaps put it to background and renice 15 ?

./cbspn >cbspn.log 2>&1 &

Works fine for me. I do get work (due to the scheduling changes in kernel 2.6, the act of getting work noticeably slows down the rest of my system for a couple seconds)...

This is LFS 5.something (it was a CVS book build plus kernel 2.6 plus NPTL).

How are you measuring whether it gets work?

bkwaz, I was using a peernod monitor to check that it was getting work. I also did a 'touch' on the file I was piping output to and it didn't say anything after the initial contact to the peernode.

If you redirect stderr with stdout, do you get any errors in that file?

(Add 2>&1 to the command to do that.)

There shouldn't be any difference between backgrounded and not, but obviously there's something. If you run it backgrounded from a terminal, then keep the terminal open, do you get any work?
