Saving tshark files in home directory

[Nirmala Shenoy]

Hello

In the nodes in our slice we run tshark to capture the traffic in the interfaces. We are unable to save the pcap files in the /home/rocky directory.

Make the home directory writable (or write to another directory where root can write). Note that you are doing touch as user rocky, but capturing as root.

# make home directory world writable

[rocky@Node1 ~]$ chmod go+rwx .

# i’m using eth0 as capture interface – that doesn’t matter
[rocky@Node1 ~]$ sudo tshark -i eth0 -w logfile
Running as user “root” and group “root”. This could be dangerous.
Capturing on ‘eth0’
