Re: [afnog]Proxy Server Hanging



thanks very much for ur advice, I really appreciate. but let me bring this to ur notice dat my server have two NIC card, one for Global IP address ansd the second for Private IP address. so if I plug the three switch into the fastethernet switch for the LAN, that means I need another switch or Hub to connect the interface that has the Global IP address with the radio link cable?
thanks for ur response.

No, he means a closed loop, e.g.

+--------+
| switch |
+-+---+--+
|___|

or ___________
| |
+------+-+ +-+------+
| switch | | switch |
+------+-+ +-+------+
|___________|

These are not good configurations (although if all your switches have
Spanning Tree enabled it should work, better not to risk it; if you are
using hubs rather than switches then it definitely will not work)

I'd suggest you keep the HP fastethernet switch as the centre of your
n etwork, and plug all the hubs into that. Then you have a tree structure
with no loops:

switch_____
/ | \ \ \
/ | \ servers
hub hub hub
||| ||| |||
PCs PCs PCs

In the above diagram, the switch means that packets from PCs on hub1 to the
server do not appear on hub2 or hub3. So you effectively have 30Mbps of
total network bandwidth available - all three hub networks can run at 10Mbps
simultaneously.

Brian.
