src host capture filter not working

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
