RE: [vox-tech] redirect to squid using router



Router setup is the easiest part.
On the router setup type

Conf t
(config)#ip wccp version 1
(config)#ip wccp web-cache 

Go to your outbound interface, the one that points to your Linux box

(config)#Interface fastethernet 0/0
(config)#ip wccp web-cache redirect out

That's about it on the router.

This is more a Linux thing than a Cisco thing.
To see if the router even sees the Linux box you can type
Show ip wccp web-cache
You should get something like this 

#show ip wccp web-cache
Global WCCP information:
    Router information:
        Router Identifier:                   206.15.244.10
        Protocol Version:                    1.0

    Service Identifier: web-cache
        Number of Cache Engines:             1
        Number of routers:                   1
        Total Packets Redirected:            544743743
        Redirect access-list:                -none-
        Total Packets Denied Redirect:       0
        Total Packets Unassigned:            26
        Group access-list:                   -none-
        Total Messages Denied to Group:      0
        Total Authentication failures:       0

And/or type

#show ip wccp web-cache view
    WCCP Routers Informed of:
        -none-

    WCCP Cache Engines Visible:
        172.27.4.249

    WCCP Cache Engines NOT Visible:
        -none-

If the router doesn't see it, it ain't right on the Linux box.

I didn't see the original post so I am not sure what you have done or or
trying to do.  But I use WCCP (Cisco protocol) to redirect all port 80
traffic to the squid box.  If squid and postgres are configured
correctly they should be broadcasting or announcing the service to the
router.
WCCP version 1 needs to be enabled on the router.  Linux does support
WCCP ver 2 because Cisco owns it and they want money.
Also the Linux kernel will have to have WCCP compiled into since it is
not native to the Linux kernel.
So the items that need to be done,
Compile WCCP into the kernel
Enable WCCP ver 1 on the router
Install and configure squid and postgres to use WCCP

I have this running on my network for web filtering for over 10,000
desktops.

Well, Squid is a tool people use on Linux, so I don't think it would be
surprising to find other Linux folks might have had the same issue.
But yeah, since it's a Cisco product, there's probably a way better
chance
of getting help FROM Cisco.  (Though I guess that depends on how good
their
suh-port is. :^) )
