I have a certain query regarding configuring squid as a caching server for ISPs. The scenario is like this:
The ISP has a Cisco router with 2MBPS bandwidth. WCCP has been enabled on the cisco router and now it communicates properly with squid. But this system works only if squid is configured as a transparent proxy. This is because WCCP redirects all outgoing http requests to port 80 of the squid and we have to redirect all traffic coming at port 80 of squid to whatever port squid is running on(say 3128), using IPCHAINS/IPTABLES.
Running the cache engine as a transparent proxy is definitely not desirable for an ISP since all http requests coming from all clients will be masqueraded by the proxy; i.e. the request will be seen as coming from squid than from the actual client.
This seems to be a limitation rather than any misconfiguration beacuse WCCP on the cisco router will only send outgoing http traffic to port 80 of caching server.
Please enlighten me on this. Major ISP's like VSNL etc. must be having some kind of caching mechanism. How do they do it then?

why is it not desirable? VSNL saves a bundle on bandwidth this way...the only people worried abt this shld be the web traffic analysis people...their servers get lesser hits!

VSNL uses NetCache...havent looked into how that solves the port 80 problem..i myself faced this when i tried to put squid in front of tomcat...wccp wont dance with 8080!!

Hi,
My fetchmail logs onto the server and downloads the mail, but after it downloads, it gives me the following errors: SMTP < 451 unable to exec qq (#4.30) SMTP listener refused delivery
The message is not flushed and fetchmail goes to the next mail and continues with the error for all the mails. I feel qmail is not recieving/forwarding the mail. Even when I use pine, am not able to send the mail. it says qq: cannot be executed.
Any ideas folks.

Sometime on May 7, noel seq assembled some asciibets to say:

your local sendmail isn't allowing fetchmail to deliver mails. try manually sending a message through sendmail. you may have to reconfigure sendmail, or easier, just tel fetchmail to use procmail for delivery.

What fetchmail does is fetching the mail from your inbox with POP3 and redirecting it to port 25 of your box. There you should have a mail transfer agent (MTA) listening and properly configured. you seem to have qmail!
Check this out too. Maybe our neighbours are one step ahead. When will our government wake up!!!
