Are there any suggestions to debug this ? 628 9537.122717 IP 1 IP 2 TCP admin > listener [FIN, ACK] Seq=1 Ack=1 Win=65535 Len=0 629 9537.122731 IP 2 IP 1 TCP listener > admin [ACK] Seq=1 Ack=2 Win=65535 Len=0 630 9537.126060 IP 2 IP 1 TCP listener > admin [RST, ACK] Seq=1 Ack=2 Win=0 Len=0 631 9537.131393 IP 1 IP 2 TCP rec > listener [SYN] Seq=0 Win=65535 Len=0 MSS=1460 SACK_PERM=1 632 9537.131435 IP 2 IP 1 TCP listener > rec [SYN, ACK] Seq=0 Ack=1 Win=65535 Len=0 MSS=1460 633 9539.940822 IP 2 IP 1 TCP listener > rec [SYN, ACK] Seq=0 Ack=1 Win=65535 Len=0 MSS=1460 634 9539.956506 IP 1 IP 2 TCP rec > listener [SYN] Seq=0 Win=65535 Len=0 MSS=1460 SACK_PERM=1 635 9539.956516 IP 2 IP 1 TCP [TCP Dup ACK 633#1] cslistener > direcpc-video [ACK] Seq=1 Ack=1 Win=65535 Len=0 636 9540.002582 IP 1 IP 2 TCP rec > listener [ACK] Seq=1 Ack=1 Win=65535 Len=0 Does this have something to do with data loss ? The socket opened from AIX to a Windows client behaves like this and the client never receives any packets.
