Set permissions:
- e.g. chmod 0700 /dev/net/tun
- if you want the device only accessible by root. Giving regular users the
- right to assign network devices is NOT a good idea. Users could assign
- bogus network interfaces to trick firewalls or administrators.
+ e.g. chmod 0666 /dev/net/tun
+ There's no harm in allowing the device to be accessible by non-root users,
+ since CAP_NET_ADMIN is required for creating network devices or for
+ connecting to network devices which aren't owned by the user in question.
+ If you want to create persistent devices and give ownership of them to
+ unprivileged users, then you need the /dev/net/tun device to be usable by
+ those users.
