One Answer:
You should not run Wireshark as root, but as a normal user as untrusted captures can cause so much breakage (security issues!). If you need more privileges for using the capture device, see:
You get the message "Cannot open display" because your user (root) is not authorized to use the X server (or the X server is not started). answered 03 Jul '14, 10:10  Lekensteyn |
