Wireshark · Wireshark-users: [Wireshark-users] Help with Output "TCP Dup ACK3#2 1320 > 22 ACK

[Mike Ciccone <mciccone@xxxxxxxxx>]

Hello,
I am having a problem with SSH.  I
can ssh from some server but not others.  I verified that there are
no access-lists blocking from doing this.  When I ran Wireshark on
my pc and tried to ssh to the server I get the following line that could
be telling me what the problem is. However, I don't understand it and was
hoping some out there could explain it to me.

Here is the line:
[TCP Dup ACK 3#2] 1320 > 22 [ACK]
Seq=1 Ack=1 win=65535 Len=0

Does this mean anything to anyone?  I'm
guessing my problem lies here.  If I ssh to a server that works...
I don't see this line

Thanks

Mike C.
