Hi, I have enabled ipsec for telnet port and did a b2b telnet on ipv6. My telnet gets closed all of a sudden at some point, happens when ipsec is enabled, I have attached the tcpdump capture. Has anybody faced with similar issue? which part of the code I need to look into? Any clues on how to debug this issue are highly appreciated. One more observation from the print log is as follows: 1. Feb 28 05:34:30: %S4810:0 %KERN-2-INT: tcp_output:1824 SEQ = 2058087702 ACK = -1213400781 len= 7 2. Feb 28 05:34:30: %S4810:0 %KERN-2-INT: tcp_output:1824 SEQ = 2058087693 ACK = -1213400781 len= 9 3. Feb 28 05:34:29: %S4810:0 %KERN-2-INT: tcp_output:1824 SEQ = 2058087693 ACK = -1213400793 len= 0 4. Feb 28 05:34:29: %S4810:0 %KERN-2-INT: tcp_output:1824 SEQ = 2058087672 ACK = -1213400796 len= 21 5. Feb 28 05:34:27: %S4810:0 %KERN-2-INT: tcp_output:1824 SEQ = 2058087675 ACK = -1213400796 len= 0 6. Feb 28 05:34:27: %S4810:0 %KERN-2-INT: tcp_output:1824 SEQ = 2058087672 ACK = -1213400814 len= 3 in line 6 and 4, they look like re transmission but length seems differing, connection is breaking every time this scenario happens, is it happening due to different lengths? regards, Madhav
