Proxy server slow internally

[sdunn]

I am running squid on a Redhat 7.0 server. I can ping external IP's fine. Its when I ping an internal IP that I get massive packet loss. I usually get 1 packet out of 50. I have 1 cable going to a hub(internal ethernet card) and 1 cable going to a switch(external ethernet card). I replaced the cable going to the hub which had no effect on the packet loss. I then plugged the cable into a different port. Which did not work either.

What else could be wrong. Is it the ethernet card gone bad? Do I have something set up wrong in Linux?

Thanks,
sdunn

This is a fun one ... you say your pings are suffering severe packet loss ..
post ifconfig [ethx] for your internal card, so we can see what errors are there.
Verify that the card is running at the same speed as the hub. Verify that the hub is capable of the speed of the card. Verify that the other systems attached to the hub are running at the same speed.

You cannot run an 100 Mbs line through a 10Mbs hub, further it is severly unwise to trust 'autosense' for speed capabilities on ANY network device since the systems which are used for this process differ from vendor to vendor.

The hub is a 10/100 mbps
eth0 is 10/100 mbps netgear
eth1 is a 10 mbps 3com
Eth0 is my internal network card
Eth1 is my DHCP ethernet card.
