Date: Thu, 12 Nov 92 23:14:21 GMT Message-ID: <MISCHLER.92Nov12231428@jolt.cubic.com> Lines: 18 Sender: news@cubic.com Nntp-Posting-Host: jolt.cubic.com I am attempting to run an NNTP server on a 386BSD 0.1 system with the patches from the patch kit. When I allow the client to pipeline requests to the server then no progress is made after a while. Netstat does not show anything in either the send or receive queue in this case (on either machine). The client is running on an SCO system, and works with servers on other SCO boxes, or on a Sun. If I don't pipeline requests then everything works OK. My initial guess was that the TCP window on the server was too small and that the client was causing the server to block by not reading the data returned before the window was filled up, but I can't find any evidence for this. I looked and found that TCP_MAXWIN is set to 64K, and this seems like it should be enough. Can anybody help out with this? Dave Mischler mischler@cubic.com
