Hi,
 
I know nothing about wireshark but I was advised to use it to check my webserver network traffic for a possible fault... the server is not local (it runs centos4) and I (having read a bit) found tshark and thought that that would probably be the way to go (although I could be wrong)./...
 
I did manage to get tshark to output files but I then couldn't read them (although I was aiming for a text file output it didn't seem to be text). I was using variations of the following
 
tshark -a duration:15 -T ps -w tsharkOP.txt
My questionis how can I output a file that I can then read / inspect?
 
Or should I be approaching this differently?
 
 
Any help / guidance / advice much apprecciated.....
 
 
Thanks
 
 
Andy
