Subject: src host capture filter
not working
Importance: High
Hi. I desperately need to see
packets coming from OR going to ip 207.35.208.194 using capture filter
Works fine with display filter only but
this is a really busy network and I need to ultimately save the capture to a
file thus need a capture filter.
[]# tshark -i eth1 -R "ip.dst == 207.35.208.194 or
ip.src == 207.35.208.194"
Capturing on eth1
13.306484 207.35.208.194 -> 208.77.1.33 SIP
Request: REGISTER sip:proxyc11b.italkbb.com
13.307911 208.77.1.33 -> 207.35.208.194 SIP
Status: 200 OK (1 bindings)
20.787232 207.35.208.194 -> 208.77.1.33 SIP
Request: REGISTER sip:proxyc11b.italkbb.com
20.788120 208.77.1.33 -> 207.35.208.194 SIP
Status: 200 OK (1 bindings)
Just host should show packets both ways
(like example above) and does not
[]# tshark -i eth1 host 207.35.208.194
Capturing on eth1
0.000000 208.77.1.33 -> 207.35.208.194 SIP
Status: 200 OK (1 bindings)
7.475218 208.77.1.33 -> 207.35.208.194 SIP
Status: 200 OK (1 bindings)
6 packets captured
Src host does not work but dst host does
work
[]# tshark -i eth1 dst host 207.35.208.194 or src host
207.35.208.194
Capturing on eth1
0.000000 208.77.1.33 -> 207.35.208.194 SIP
Status: 200 OK (1 bindings)
7.475218 208.77.1.33 -> 207.35.208.194 SIP
Status: 200 OK (1 bindings)
6 packets captured
This shows that src host does not work all
by itself either
[]# tshark -i eth1 src host 207.35.208.194
Capturing on eth1
0 packets captured
