How to read the interface name from a .pcapng file using tshark?

I am trying to run this tshark command :

tshark -r $file -T fields -E separator=/t -e frame.number -e frame.time -e frame.protocols -e frame.len -e frame.interface_id -e frame.interface_name

I get this warning :

** (process:30955): WARNING **: 'frame.interface_name' isn't a valid field! tshark: Some fields aren't valid

But I am able to see the field when I open the file in Wireshark ?

What is the right way to access the interface_name info?

I am using the following tshark version - 

TShark 1.12.1 (Git Rev Unknown from unknown)

I tried updating wireshark -

$ sudo apt-get install wireshark Reading package lists... Done Building dependency tree
Reading state information... Done wireshark is already the newest version. You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: isc-dhcp-relay : Depends: isc-dhcp-common (= 4.2.2.dfsg.1-5+deb70u8) but 4.2.2.dfsg.1-5+deb70u8 is to be installed isc-dhcp-server : Depends: isc-dhcp-common (= 4.2.2.dfsg.1-5+deb70u8) but 4.2.2.dfsg.1-5+deb70u8 is to be installed libsnmp-perl : Depends: perl (>= 5.14.2-21+deb7u5) but 5.14.2-21+deb7u3 is to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

It says wireshark is already the newest version.

Solution

  • Which version of tshark are you using? Run tshark -v to check.

    The frame.interface_name display filter is only available beginning with version 2.4.0, so maybe you have an older version of tshark in your %PATH%?

    Note that you can check for the availability of any display filter on the Wireshark Display Filter Reference Page.
