Hello Developers,
 
 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
