Looking at the tcp stream, below, of a smtp conversation, it appears there is 5 second delay before the actual smtp conversation begins. Is this normal behavior. If not, any ideas what/where specifically, Any ideas of what are the next wireshark diagnostic tools I should be using to further identify the problem. 15047 02:57:33.441270000 192.168.0.209 192.168.0.239 TCP 66 54398 > smtp [SYN] Seq=0 Win=8192 Len=0 MSS=1460 WS=4 SACK_PERM=1 15048 02:57:33.441494000 192.168.0.239 192.168.0.209 TCP 66 smtp > 54398 [SYN, ACK] Seq=0 Ack=1 Win=14600 Len=0 MSS=1460 SACK_PERM=1 WS=16 15049 02:57:33.441515000 192.168.0.209 192.168.0.239 TCP 54 54398 > smtp [ACK] Seq=1 Ack=1 Win=65700 Len=0 15237 02:57:38.461112000 192.168.0.239 192.168.0.209 SMTP 97 S: 220 pmx1.mydomain.biz ESMTP Postfix Thanks in advance ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe
