tcpdump on monitors

is it possible to tcpdump default_tcp on GTM for a server? I need to know what response i am gettting back from sever for the default_tcp (TCP Half Open) connection.



Please advise.


Thanks in advance

  • Hi Francisco,


    I suppose TCP Half Open connections basically send out TCP-SYN versus the acknowledgement. In that case I suppose you can use TCPDUMP in the following manner



    tcpdump -nnvv -i br0 'tcp[tcp-syn] & (tcp-syn)' != 0



    I hope this helps
