Greetings to all,
I am working in HP-UX
platform.
I am using the 0.10.5 ethereal
version
I have a problem with the -w option of
mergecap.
Capture five packets
# tethereal -c 5 -w one.cap
Capturing on
lan0
5
Capture five packets
# tethereal -c 5 -w two.cap
Capturing on lan0
5
Combine using mergecalp
# mergecap -w three.cap one.cap two.cap
mergecap: couldn't open output
file
But if this file already exists it works fine
touch three.cap
mergecap -w three.cap one.cap two.cap
tethereal -r three.cap
