Gatrway 9.x has tshark pre-installed. I’m trying to install wireshark via package manager but getting error:…
W: Failed to fetch http://security.debian.org/pool/updates/main/w/wireshark/wireshark_1_...deb
Temporary failure resolving ‘security.debian.org’
But I was able to install it via “sudo apt-get install wireshark”!!!
On related subject…
When I run wireshark on gateway it reports there are no interfaces so nothing to capture. Yet, when I run tshark it shows packet transactions. What is tshark monitoring that wireshark cannot?
