No protocol specified

Créer une nouvelle règle de politique dans /usr/share/polkit-1/actions/

Sudo nano /usr/share/polkit-1/actions/wireshark.policy

et ajoutez les lignes ci-dessous:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE policyconfig PUBLIC
 "-//freedesktop//DTD PolicyKit Policy Configuration 1.0//EN"
 "http://www.freedesktop.org/standards/PolicyKit/1/policyconfig.dtd">

<policyconfig>

  <action id="org.freedesktop.policykit.pkexec.run-wireshark">
    <description>Run FlashTool</description>
    <message>Authentication is required to run Wireshark</message>
    <defaults>
      <allow_any>no</allow_any>
      <allow_inactive>no</allow_inactive>
      <allow_active>auth_admin_keep</allow_active>
    </defaults>
    <annotate key="org.freedesktop.policykit.exec.path">/usr/bin/wireshark</annotate>
    <annotate key="org.freedesktop.policykit.exec.allow_gui">TRUE</annotate>
  </action>

</policyconfig>

Puis créez un nouveau script wireshark-pkexec

Sudo nano /usr/bin/wireshark-pkexec

et ajoutez les lignes ci-dessous:

#!/bin/sh
pkexec "wireshark" "$@"

et ajouter le drapeau exécutable

Sudo chmod +x /usr/bin/wireshark-pkexec

Et enfin créer un nouveau fichier de bureau

nano /usr/share/applications/wireshark-pkexec.desktop

et ajoutez les lignes ci-dessous:

[Desktop Entry]
Name=Wireshark as root
GenericName=Network Analyzer
Comment=Network traffic analyzer
