Wireshark · Wireshark-users: [Wireshark-users] a question on capture filter

[esolve esolve <esolvepolito@xxxxxxxxx>]

Hi,

     I want to capture packets with capture filter like:

     host 138.56.169.25 and (not host 138.52.69.45) and (not ntp) and (not igmp)

     so the packets I want to capture are with 138.56.169.25 as src/dst, but without 138.52.69.45 as src/dst, and should not be ntp or igmp packets.

     But the capture results are not as expected, can anyone know where is wrong? thanks!
