Dotaz: Problem zapnut wireshark ako root

[darren97]

Ahojte, pred aktualizaciou Ubuntu som spustal wireshark: sudo wireshark Teraz po update mi hadze toto: QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root' Invalid MIT-MAGIC-COOKIE-1 keyQXcbConnection: Could not connect to display :0 Aborted

Pozeral som nejake "solutions" na nete, ale velmi som sa z toho nevyznal. Vedel by niekto poradit?

Sudo nejspis neprenasi spravne MIT-MAGIC-COOKIE-1, budto si ji preneste rucne a nebo si dejte localhost do controllistu.

Mas nejaky rozumny dovod na spustanie Wiresharku pod rootom?

[darren97]

Lebo ked zapnem wireshark bez sudo, tak ked chcem spustit: Starting capturing packets....vyhodi mi to Permission denied. Preto sa to snazim spustat ako root, pred aktualizaciou islo vsetko bez problemov.

/usr/share/doc/wireshark/README.Debian:

I./b. Installing dumpcap and allowing non-root users to capture packets

Members of the wireshark group will be able to capture packets on network interfaces. This is the preferred way of installation if Wireshark/Tshark will be used for capturing and displaying packets at the same time, since that way only the dumpcap process has to be run with elevated privileges thanks to the privilege separation[1].

Note that no user will be added to group wireshark automatically, the system administrator has to add them manually. After a user is added to the wireshark group she/he may need to log in again to make her/his new group membership take effect and be able to capture packets.

...

The installation method can be changed any time by running: dpkg-reconfigure wireshark-common

Máš dvě věci se kterými se musíš vyrovnat. jednak to, kdo má právo zachytávat pakety na rozhraní a ta rada tu už proběhla. a druhá věc je, že X server má obecně restrikováno kdo na něm může zobrazovat. Takže politika zobrazení se pravděpodobně zpřísnila a musíš ji buď zpětně uvolnit a nebo zvolit tu první metodu.
