Post #58,694 by jake123 10/23/02 5:26:47 AM Reply	It appears that the answer is.... squid. My guess is that Bell (the ISP in question) is messing with the packets in some way to prevent what we're doing here. I think I'm going to recommend that these guys consider switching providers in the medium term... my provider doesn't play games like this... and the ToS at Bell explicitly permit them to play games like this. --\n-------------------------------------------------------------------\n* Jack Troughton jake at consultron.ca \n [link\|http://consultron.ca\|http://consultron.ca] [link\|irc://irc.ecomstation.ca\|irc://irc.ecomstation.ca] \n Laval Qu\ufffdbec Canada [link\|news://news.consultron.ca\|news://news.consultron.ca] *\n-------------------------------------------------------------------

I currently STILL have my ipchains from RH7.0 as my Firewall.. ;) but on 2.4 ECN is on by default and SOME ISPs see that BIT being set as Spoofing... either way... (too or from) Also Make sure you have Squid 2.4Stable6 or later (I believe it's the latest), as it fixes something like that to. I currently do not have a 2.4 Box to play with RIGHT this second, as I am doing some other work needed for money to come in... ON WINDOWS!!! AHHHH!!!!! Tis a mailing system manager called MailManager... I am doing an extremely large setup right now on 2 machines... I'd like to run it on Linux but the Program BARFS on Wine... Currently going through 16 - 8GB files and validating everything then sorting them all in one big batch... ewe... Windows is cranking through though... for how long I dunno... edit: Added Squid comment `[link\|mailto:curley95@attbi.com\|greg] - Grand-Master Artist in IT [link\|http://www.iwethey.org/ed_curry/\|REMEMBER ED CURRY!!!] Your friendly Homeland Security Officer reminds: Hold Thumbprint to Screen for 5 seconds, we'll take the imprint, or Just continue to type on your keyboard, and we'll just sample your DNA.` Edited by gfolkertold Oct. 23, 2002, 01:29:08 PM EDT Expand All History

Still and all, it's worth a look and a switch to see if it improves things. Thanks for the heads up. BTW- what exactly does that one do? --\r\n-------------------------------------------------------------------\r\n* Jack Troughton jake at consultron.ca \r\n http://consultron.ca irc://irc.ecomstation.ca \r\n Laval Qu\ufffdbec Canada news://news.consultron.ca *\r\n-------------------------------------------------------------------
