It allows to show some +information about network status, including the routing +table, content of resolv.conf and nsswitch.conf, active +TCP/IP connections, running daemons, etc., and to dump those +information to a file.

There is no limitation on the number of Ethernet +devices that setnet.sh can manage, but you should be careful +with having more than one <b>dhclient</b> processes running, +since each of them will try to add a default gateway to the +kernel routing table.</p> + +<p style="margin-top: 1em"><b>SECURITY +CONSIDERATIONS</b></p> + +<p style="margin-left:6%;">Configuring networking is an +administration task, and setnet.sh requires root privileges +to work properly. It is possible to allow a regular user to +run setnet.sh, e.g. by using sudo(8) or sup(1) (see +https://sup.dyne.org/ for more information about sup).</p> + +<p style="margin-left:6%; margin-top: 1em">setnet.sh can +recognise if it is running under sudo(8) or sup(1), by +looking at the content of the environment variables +SUDO_UID/SUP_UID, SUDO_GID/SUP_GID, and SUDO_USER/SUP_USER. +When setnet.sh is run under sudo(8) or sup(1), some +functionalities are disabled. In particular, loading and +editing an alternate wpa_supplicant configuration file is +forbidden (and for obvious reasons, since this would in +principle allow the sudoer to edit *any* file in your +system).</p> + +<p style="margin-left:6%; margin-top: 1em">Linux +January 06, 2017 Linux</p> +<hr> +</body> +</html> |
