such as tcpdump.

-@item network
+@cindex network
+@item network [@var{netname}]
If @var{netname} is given, switch to that network.
Otherwise, display a list of all networks for which configuration files exist.
+@cindex fsck
+@item fsck
+This will check the configuration files for possible problems,
+such as unsafe file permissions, missing executable bit on script,
+unknown and obsolete configuration variables, wrong public and/or private keys, and so on.
+
+When problems are found, this will be printed on a line with WARNING or ERROR in front of it.
+Most problems must be corrected by the user itself, however in some cases (like file permissions and missing public keys),
+tinc will ask if it should fix the problem.
