Very sorry, my mistake, I do not see it any more, I do
not understand what I did, now my pings are ~0.3ms,
so all is well about that.
Ping -f has no impact on the other pings (I must have dreamt it)
But I was doing all with ssh, forgetting about the ssh
part when I did my experiments, so I did on

Another thing even more mysterious:
A ping between A and B takes 3 ms average
When A is the ping initiator, a
"while [ 1 ];do ls;done" on B makes the ping
take 0.3 ms, same thing if the load is done
on the host!!
Believe it or not, uml works faster on a loaded host!

It gets stuck by a ping -f from another uml with my clownix
process in between both uml, transfering packets from one
socket to the other.
1 When uml A does a ping -f to B, the select of B is completely
blocked, I can ssh into B and look around without feeling latency,
ps -ef dumps very fast a

Hello,
I am doing networking with ulm, and I have a pb,
on one machine I run a piece of software as under:
while (1)
{
tv.tv_sec = 1;
tv.tv_usec = 0;
select( 1, NULL, NULL, NULL, &tv );
tell_time();
}
I get 1200 milli-sec with each loop, when all is
nominal, but when I do a ping -
