4.13-10ubuntu5 in 21.10 and 5.2-1ubuntu1 in jammy are failing as well, with debug log different when compared to version 3 involved here:

In the code at http://www.squid- cache.org/Doc/code/wccp2_8cc_source.html I miss some debug output in the loop processing the packet /* Go through the data structure */ so would need to rebuild the package or to involve debugger. I was not able to find any documentation of squid listing supported/tested wccp servers but at this point this looks like an issue to be reported upstream. There is no reason to consider wccp packets from IOS 15.8(3)M2 invalid. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1952158 Title: squid does not accept WCCP of Cisco router since 3.5.27-1ubuntu1.12 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/squid/+bug/1952158/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
