user seperated by a ';' like this:
<username>;<tunnelif>;<tunneladdr>;<tunneladdrmask>
<username> is the sytem username.
<tunnelif> is the Tunnelif, which is usually tunl1 (or
tunl2 or tunl3 ...). You must not use tunl0 !
<tunneladdr> and <tunneladdrmask> describe the subnet
which is routed through the tunnel interface. eg
foo;tunl5;1.1.1.1;255.255.255.255 means a host route to
1.1.1.1 through tunl5.
/var/autotunnel/secret:
The default Configuration for autotunnel Client is
/var/autotunnel/secret. It should be only
readable by root as it contains the password
There are no Comments allowed and it should only
contain 1 line.
