Heh
This actually sounds a lot like a retransmit issue....
>From a shell (as root) try the following command:
while true
do
netstat -s | grep retrans
sleep 3
clear
done
This will report the network retransmits occurring on the network
interface(s).
If you see this number grow rapidly (several per second or per 3 seconds,
in this case)
then it's a good indication that your NIC is retransmitting packets with
the switch or
router it's plugged into. I know this to be a common issue with Cisco
devices. It generally
occurs because of a duplex mismatch. ie: router/switch has the port for
your server configured as
Auto-negotiate, but your server is attempting for force 100/full (or
vice-versa).
Might be something to consider/look at.

Re: Squid disconnects internet...
Hi, Thank you for your response, yes, I used the package from debian
(apt) it has been precompiled with that option, as a transparent proxy
it works, it justs becomes intermittent, it caches some pages then it
doesnt connect to anything, I even get some statistics from sarg (squid
report tool) but every 2 to 3 minutes the clients loose all conection to
the internet and then it comes back in other 2 to 3 minutes and so on...
MSN Clients disconnects, Firefox just say looking up for the website and
thats it, and then everything works fine again... the strangest thing.....
( I am changing the network cards today, just to rule that out...)
