From another PC, can you ping your squid box by IP address?

Or, from the squid box, can you ping anything on your network by its IP address?

Ok good. Check your logs. The file were concerned with should be located at [green][tt]/var/log/squid/access.log[/tt][/green]. As the name implies access.log contains a log of every webpage that has been accessed through your proxy. You might want to
Code: 
tail -f /var/log/squid/access.log
while you're trying to get to a website from a client.

On a side note, after enabling the bonded interface have you restarted squid. It might need to rebind to the bonded interface.

What messages do the clients report when squid is broken?

the access.log is blank no info.

squid is definitely running, right? You can see it in ps -ef?

What port is it listening on, 8080? If so, can you connect to that port okay from another PC? Try telnet squidhostname 8080 and see if the connection is accepted.

What browser(s) are you using? How have you configured the proxy in those browsers? Are they set up to use auto configuration?

Annihilannic.

You need an acl statement to allow your clients to access to proxy.

Code: 
acl <acl_name> src <your.ip.client.subnet/netmask>
Then another line to use it.
Code: 
http_access allow <acl_name>

Your squid.conf works but it's a little too open for my tastes but I don't see any issues with it.

Are you trying to get more bandwidth or provide redundancy with the bonded interface?

Depending on the mode, including mode 0 (balance round-robin), you will need to configure the connecting switch(s) with Link Aggregation. Not necessarily LACP (802.3ad) but they need to function as one interface. With modes 1, 5 & 6 you don't need to do anything on the switch; active-backup, balance-tlb and balance-alb, respectively.

im working with mode 0 and i did the link aggregation, but still the same issue, what other mode can i use to balance the traffic?

thanks

Can you ping the bonded interface reliably?

If you have your switch(es) configured for link aggregation you should enable lacp (802.3ad) and use mode 4.

If that fails, try mode 1 or 5. I use both with no problems and I didn't have to do anything on my switches. These modes are more for reliability than increased bandwidth, including mode 6. In mode 1 one NIC is active and the other is used as backup in case the first one fails, fault tolerance. In mode 5 the transmits are load balanced while the slave receives the traffic.
