For close on the last 6 months, when I connect to my ISP (teleport.com) using my 28.8 Microcom, pppd and Linux Netscape 4.06, I've had problems recieving data from 'altavista.digital.com'. Initially access was sporadic, now it fails 100% of the time. More recently I've started to have the same problem with 'www.wellsfargo.com' or 'https://banking.wellsfargo.com'. If I reboot into Win NT 4.0 (connect to the same ISP), I can access the problem sites with no problems (using IE4.0). In each case, the TCP connection is made, Netscape shows this (as does netstat and a brief sequence of XMIT/RECV on the modem). However, no data is ever recieved by the application (confirmed by no RECV light on the modem, just the occasional blinking of the XMIT light - Netscape resending?) Eventually the http connection will time out. I've upgraded -stable, the Linux version of Netscape to v4.06, tried my old BSD Netscape 3.0 all with the same results. The BSD Netscape _used_ to work fine, as did the Linux versions. I posted to -stable and someone suggested I disable TCP extensions (I'd already tried this) and also to try sending large ICMP packets (1472) to see if it was a fragmentation problem. The pings worked fine. I realise this sounds kind of crazy, but I really don't think it is an ISP issue, but I'm all out of ideas as to what to try. If anyone has any ideas, I'd love to hear them. It's starting to drive me nuts. Tony To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
