Hi All,

I am new to ethereal sniffer.

I can capture the packets using ethereal.

However, I am unable to apply the capture filters.

I even looked at the mailing list archives but it was of no help.

Please help me out with this simple stuff.

I want to capture the packets of only two protocols i.e. h225 and h245.

I tried the following filter string for capture filter:

a) h225
b) h225 h245
c) proto h225
d) proto h245
e) proto h225 h245
f) ether proto h225 h245

but it was of no help.

Apart from filtering these specific protocols during capture, I also want to
filter
specific hosts.

I know you guys understand my requirements very well.

I am looking for your help in terms of exact syntax that I should put during
the Capture -> Start... -> Filter:

Looking for a reply.

Thanks
Vipin
