Hi, What kinds of errors are you getting? Timeouts? Anything in your cache.log? Try to get the access.log lines that represent the problem.
Here is a minimal troubleshooting guide: 1) Try to access them without squid, using any web browser (explorer, firefox). 2) Try to access using elinks (text browser with some javascript & frames support) from a squid server without wccp. 3) Try to access them using plain old telnet without wccp (just to test your TCP stack, perhaps you may have a broken tcp timestamps implementation, for instance). 4) Try to access them using telnet from your Cisco 7206 using different ip source address (to discard routing problems). Hope this helps, On 10/11/06, Tom Warren <[EMAIL PROTECTED]> wrote:
A few days ago we suddenly began experiencing hangs and getting (browser) error pages for many webmail and other popular sites. First complaint was about Yahoo mail on Monday, then Hotmail yesterday, and today MSN won't load either! The problem affects both IE6 and Firefox 1.5.0.7 and can be worked-around by excluding the user's IP from wccp on the router or by pointing directly to the cache in the browser's proxy settings. We have tried a multitude of suggestions parsed from this and other forums, including the MSS iptables fix, 'Accept-Encoding deny', no_cache, disabling various TCP parameters in Linux and also removing things that break http like 'reload_into_ims on'. But the problem persists and seems to be getting worse over time. No changes were made to the cache configuration prior to the start of the problem. Yesterday we thought we were able to solve the issue by clearing cookies at one customer site, but the problem returned and now clearing cookies does nothing. We thought it may be due to NAT but today it is affecting workstations in our NOC on public IPs directly connected to our core router. I saw a similar complaint regarding Yahoo mail recently and I'm curious if anyone else is having similar problems. I'll be happy to post any pertinent information if I can get an idea of where to start troubleshooting and what information is required. The basics are Fedora 4, Squid2.6STABLE4 using WCCP from a Cisco 7206. Regards, Tom
