Hello list, I'm seeing strange? networking behaviour with my FreeBSD server, and it seems that this list is tne right to ask ;) Suppose, there is outgoing connection for whom dynamic rule is created (that's how I noticed it - ipfw logs denied packets). My 4.4-Release FreeBSD is hostA, something on the next end is hostB - smtp server. That's how the end of smtp session looks:
_Host tcpflags seq nseq ack data_ hostA ( [PSH,ACK], seq1, nseq1, ack1, "QUIT" ) hostA ( [FIN,ACK], nseq1, -- , ack1 ) hostB ( [[ACK], ack1, -- , nseq1) hostB ( [PSH,ACK], ack1, nseq2, nseq1, "221 Bye") hostA ( [RST], nseq1, -- , -- ) hostB ( [FIN,ACK], nseq2, -- , nseq1) hostB ( [ACK], nseq2+1, -- , nseq1+1) hostB ( [FIN,PSH,ACK], ack1, nseq2, nseq1+1) ... I'm wondering, why FreeBSD sends RST so early and hostB tries to send something back (and that didn't match dynamic rule, which is destroyed upon RST (I suspect))? Is it possible to change this? (so that conversation between hostA and hostB ended normally) TIA Paulius To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-net" in the body of the message
