--- Comment #9 from Konstantin <[email protected]> --- (In reply to Jeremy Harris from comment #8) > If that ACK made it to the wire, your client should see it > and should close the TCP connection. I can see the ACK in a tcpdump but the client never initiates the FIN. The FIN is always coming after the delay from the exim server. I also couldn't find a way to change the client behaviour. Here is my tcpdump output: 15:22:58.643883 lo In IP (tos 0x0, ttl 64, id 64270, offset 0, flags [DF], proto TCP (6), length 96) 127.0.0.1.25 > 127.0.0.1.34252: Flags [P.], cksum 0xfe54 (incorrect -> 0x7514), seq 294:338, ack 28, win 512, options [nop,nop,TS val 944245643 ecr 944245643], length 44: SMTP, length: 44 221 xp1w1.west.ig.local closing connection 15:22:58.643887 lo In IP (tos 0x0, ttl 64, id 21373, offset 0, flags [DF], proto TCP (6), length 52) 127.0.0.1.34252 > 127.0.0.1.25: Flags [.], cksum 0xfe28 (incorrect -> 0x3b7a), ack 338, win 511, options [nop,nop,TS val 944245643 ecr 944245643], length 0 15:22:59.044693 lo In IP (tos 0x0, ttl 64, id 64271, offset 0, flags [DF], proto TCP (6), length 52) 127.0.0.1.25 > 127.0.0.1.34252: Flags [F.], cksum 0xfe28 (incorrect -> 0x39e7), seq 338, ack 28, win 512, options [nop,nop,TS val 944246044 ecr 944245643], length 0 15:22:59.045136 lo In IP (tos 0x0, ttl 64, id 21374, offset 0, flags [DF], proto TCP (6), length 52) 127.0.0.1.34252 > 127.0.0.1.25: Flags [F.], cksum 0xfe28 (incorrect -> 0x3855), seq 28, ack 339, win 512, options [nop,nop,TS val 944246044 ecr 944246044], length 0 15:22:59.045152 lo In IP (tos 0x0, ttl 64, id 64272, offset 0, flags [DF], proto TCP (6), length 52) -- You are receiving this mail because: You are on the CC list for the bug. -- ## subscription configuration (requires account): ## https://lists.exim.org/mailman3/postorius/lists/exim-dev.lists.exim.org/ ## unsubscribe (doesn't require an account): ## [email protected] ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
