well... I've tried to use wccp on another mashine. This time this was=20
Linux. With ip_wccp module loaded (I know it works squid <-> Cisco=20
router).

But still Cisco with ordinary squid does not work together. tcpdump goes=20
priv :) one with --ipip and second one with --gatewaying (dump2 - empty).
When I've tried to add mixed types (dump3) nothing was changed - still no=
t=20
working.


I've got in my logs:
charon  wccpd:            HERE_I_AM: WebCache at 212.1.6.3 became usable
charon  wccpd:            WebCache at 212.1.6.3 enabled
charon  wccpd:            executeCmd: enable-cache: 65280
charon  wccpd:            WebCache at 153.1.0.4 changed hash information
charon  wccpd:            WebCache at 212.1.6.3 changed hash information
charon  wccpd:            WebCache at 153.1.0.4 changed hash information
charon  wccpd:            WebCache at 212.1.6.3 changed hash=20
information

..and so on...

first of all some smarter script must be made, because multiple types of=20
caches with mixed types of encapsulation are unusable not.
Next - when a cache is calling HERE_I_AM wccpd automaticaly enables it.=20
Its wrong, because:
- some cache might be broken
- some cache I might not want to use
- I might to diable this cache from router...

... well another vote for somekind of config :)
