tshark error help!

strider82 · 09-07-2010, 10:14 PM

Hello,

I am trying to set up a multiple file write option in tshark and cannot get it running.

root# tshark -i eth0 -b duration:60 -w test

Running as user "root" and group "root". This could be dangerous.
Capturing on eth0
tshark: The file to which the capture would be saved ("test") could not be opened: No such file or directory.

I created a dummy file, but the same error is thrown. Any ideas?
Thanks

Q: have you tried an arbitrary filename/specific file path (e.g. "-w /tmp/xyz") instead of the default path and the filename "test" (which also happens to be a built-in command)?

Thanks for your reply. The problem occurred as I tried writing as root to a mount point which is not allowed. Using test as the file name works otherwise.
