However, it is not strictly necessary that you call tinc with the -n

Each tinc daemon should have a name that is unique in the network which
it will be part of. The name will be used by other tinc daemons for
identification. The name has to be declared in the

.TP
-\fBConnectTo\fR = <\fIname\fR> (optional)
+\fBConnectTo\fR = <\fIname\fR>
Specifies which host to connect to on startup. Multiple \fBConnectTo\fR variables
may be specified, if connecting to the first one fails then tinc will try
the next one, and so on. The names should be known to this tinc daemon
(i.e., there should be a host configuration file for the name on the ConnectTo
line).

\fBHostnames\fR = <\fIyes|no\fR> (no)
This does not affect resolving hostnames to IP addresses from the
host configuration files.
.TP
+\fBInterface\fR = <\fIdevice\fR>
+If you have more than one network interface in your computer, tinc will
+by default listen on all of them for incoming connections. It is

+\fBInterfaceIP\fR = <\fIlocal address\fR>
+If your computer has more than one IP address on a single interface (for

+on several interfaces at the same time though, if they share the same IP
+address.
+.TP
\fBKeyExpire\fR = <\fIseconds\fR> (3600)
This option controls the time the encryption keys used to encrypt the data
are valid. It is common practice to change keys at regular intervals to
make it even harder for crackers, even though it is thought to be nearly
impossible to crack a single key.
.TP
-\fBName\fR = <\fIname\fR> (required)
+\fBName\fR = <\fIname\fR> [required]
This is the name which identifies this tinc daemon. It must be unique for
the virtual private network this daemon will connect to.
.TP
-\fBPingTimeout\fR = <\fIseconds\fR> (5)
+\fBPingTimeout\fR = <\fIseconds\fR> (60)
The number of seconds of inactivity that tinc will wait before sending a
probe to the other end. If that other end doesn't answer within that
same amount of seconds, the connection is terminated, and the others
will be notified of this.
.TP
-\fBPrivateKey\fR = <\fIkey\fR>
+\fBPrivateKey\fR = <\fIkey\fR> [obsolete]
The private RSA key of this tinc daemon. It will allow this tinc daemon to
authenticate itself to other daemons.
.TP
-\fBPrivateKeyFile\fR = <\fIfilename\fR>
+\fBPrivateKeyFile\fR = <\fIfilename\fR> [recommended]
The file in which the private RSA key of this tinc daemon resides.

specified in the configuration file.
.TP
-\fBTapDevice\fR = <\fIdevice\fR> (/dev/tap0)
+\fBTapDevice\fR = <\fIdevice\fR> (/dev/tap0 or /dev/net/tun)
The ethertap or tun/tap device to use. tinc will automatically detect what
kind of tapdevice it is.

.PP
.TP
-\fBAddress\fR = <\fIIP address\fR> (required)
+\fBAddress\fR = <\fIIP address\fR> [recommended]
The real address or hostname of this tinc daemon.
.TP
+\fBIndirectData\fR = <\fIyes\fR|\fIno\fR> (no) [experimental]
+This option specifies whether other tinc daemons besides the one you
+specified with ConnectTo can make a direct connection to you. This is
+especially useful if you are behind a firewall and it is impossible to
+make a connection from the outside to your tinc daemon. Otherwise, it
+is best to leave this option out or set it to no.

\fBPort\fR = <\fIport number\fR> (655)
The port on which this tinc daemon is listening for incoming connections.
.TP
-\fBPublicKey\fR = <\fIkey\fR>

The public RSA key of this tinc daemon. It will be used to cryptographically
verify it's identity and to set up a secure connection.

+\fBPublicKeyFile\fR = <\fIfilename\fR> [obsolete]
The file in which the public RSA key of this tinc daemon resides.

-a connection with that host.

-\fBSubnet\fR = <\fIaddress/masklength\fR> (optional)
+From version 1.0pre4 on tinc will store the public key directly into the
+host configuration file in PEM format, the above two options then are not
+necessary. Either the PEM format is used, or exactly
+one of the above two options must be specified
+in each host configuration file, if you want to be able to establish a

+.TP
+\fBSubnet\fR = <\fIaddress/masklength\fR>
The subnet which this tinc daemon will serve. tinc tries to look up which other
daemon it should send a packet to by searching the appropiate subnet. If the
packet matches a subnet, it will be sent to the daemon who has this subnet in his
network address and 24 is the number of bits set in the netmask. Note that subnets
like \fI192.168.1.1/24\fR are invalid! Read a networking howto/FAQ/guide if you
don't understand this.
+.TP
+\fBTCPonly\fR = <\fIyes\fR|\fIno\fR> (no) [experimental]
+If this variable is set to yes, then the packets are tunnelled over a
+TCP connection instead of a UDP connection. This is especially useful
+for those who want to run a tinc daemon from behind a masquerading
+firewall, or if UDP packet routing is disabled somehow. This is

@cindex PrivateKey
This is the RSA private key for tinc. However, for safety reasons it is

accidental eavesdropping if you are editting the configuration file.
-@item @strong{PrivateKeyFile = <path>} (recommended)
+@item @strong{PrivateKeyFile = <path>} [recommended]
@cindex PrivateKeyFile
This is the full path name of the RSA private key file that was

relative directory.
-@item @strong{TapDevice = <device>} (/dev/tap0)
+@item @strong{TapDevice = <device>} (/dev/tap0 or /dev/net/tun)
@cindex TapDevice
The ethertap device to use. Note that you can only use one device per
daemon. The info pages of the tinc package contain more information
about configuring an ethertap device for Linux.
-@item TCPonly = <yes|no> (no, experimental)
-@cindex TCPonly
-If this variable is set to yes, then the packets are tunnelled over a TCP
-connection instead of a UDP connection. This is especially useful for those

+@item IndirectData = <yes|no> (no) [experimental]
@cindex IndirectData
This option specifies whether other tinc daemons besides the one you

@cindex PublicKeyFile
This is the full path name of the RSA public key file that was generated
by ``tincd --generate-keys''. It must be a full path, not a relative
