Hello,
am trying to debug why often times, my ssh client timeout trying to establish connection to an ssh server (F5 device)...
Often times, I see a SYN sent twice, then server responding with an ACK, then an SYN/ACK, then my client sends RST.
Other times, I see several SYN re-transmits, then ACK response, then SYN/ACK, then ACK from client and connection getting established!
This is all not very normal, right? especially the ACK in response to a SYN? that should cause clients to fail to continue establishing a connection, right?
Thanks a lot for your input, I know this is not wireshark issue!
Mohamed,
