There are some configuration files in /etc/wireshark, but wireshark itself ignores it.
Here goes strace:
egrep '(preferences|wireshark.conf|init.lua)' /tmp/ws.open
4872 open("/usr/share/wireshark/init.lua", O_RDONLY) = 25
4872 open("/usr/share/wireshark/preferences", O_RDONLY) = -1 ENOENT (No such file or directory)
4872 open("/usr/share/wireshark/wireshark.conf", O_RDONLY) = -1 ENOENT (No such file or directory)
4872 open("/home/gq/.wireshark/preferences", O_RDONLY) = 25
Hi Alexander, 2017-03-29 12:23 GMT+02:00 Alexander GQ Gerasiov <gq@debian.org>: $ ls /etc/wireshark/ init.lua $ ls -alh /usr/share/wireshark/init.lua lrwxrwxrwx 1 root root 23 Mar 9 08:33 /usr/share/wireshark/init.lua -> /etc/wireshark/init.lua init.lua is the only shipped global config file and it is read. I guess you mean if you create such files they are not read. Cheers, Balint
