However, that doesn't agree with what the docs say: cache_peer hostname type http-port icp-port [options] taken from http://www.squid-cache.org/Doc/config/cache_peer/ As such the icp-port is defined as 3130 by our config. Looking at the 'icp_port' command (from the same site) I see that it says the old default was 3130 - hence why it worked at 2.7 - but is now 0 (disabled) from 3.0 onwards. This was not mentioned in the ChangeLog file or the RELEASENOTES at all. John. -- John Horne, University of Plymouth, UK Tel: +44 (0)1752 587287 Fax: +44 (0)1752 587001
