Both, RFC 1323 and the socket buffer space size, are not related at all. Btw., read the other threads about TCP problems in -hackers that took place within the last four or five days. Also read the commit message for tcp_output.c revision 1.27 to learn what the actual problem has been (and why it is related to your bumping the send buffer space). -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
