According to standards they will give up after 5 days or so.

Have you considered teergrubing them instead? That ought to
fix the bandwith problem. And it is not so fun for whoever has
the spam server either - either disrupting some spammers operation
or harassing some server admin into making his box un-abuseable.

I thought it would be easier than that. However, I did write a
program that keeps the connection open forever (until the SPAM-server
hangs up). This slows down the servers. I also thought that I could
make multiple connections to the server and never hang up, depriving
the SPAM-server of resources. However, I can't make a new connection
with the same socket (don't know why), EISCONN, without closing the
previous.
This means that I need a new socket for each connection. I run out
of sockets before the SPAM-servers do.

Methinks you forgot the smiley on here.
Hi,
Are there any patches available to read the battery status of a Toshiba
Tecra S1 laptop (module PT831C-11UDL)?
I currently have no way to read the battery time left - and when it runs
out the system comes crashing down -- ext3 to the rescue!
The last kernel I tried was 2.6.0-test5.
Any help would be appreciated.
TIA
Bernt
