Hi,

 

         I would like to get some help to understand why after several TCP keep-alive( set to 45 seconds for debugging ) packets I see a RST negotiation here. 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.

 

Thanks,

Mohan
