<code>define <name> telnet <portNumber> [global]</code><br>

|

<code>define <name> telnet <servername>:<portNumber></code>
|
||||
<br><br>
|
||||
|
||||
First form, <b>server</b> mode:<br>
|
||||
Listen on the TCP/IP port <code><portNumber></code> for incoming
|
||||
connections. If the second parameter global is <b>not</b> specified,
|
||||
the server will only listen to localhost connections.
|
||||
<br><br>
|
||||
|
||||
<br>
|
||||
To use IPV6, specify the portNumber as IPV6:<number>, in this
|
||||
case the perl module IO::Socket:INET6 will be requested.
|
||||
On Linux you may have to install it with cpan -i IO::Socket::INET6 or
|
||||
apt-get libio-socket-inet6-perl; OSX and the FritzBox-7390 perl already has
|
||||
this module.
|
||||
<br><br>
|
||||
this module.<br>
|
||||
Examples:
|
||||
<ul>
|
||||
<code>define tPort telnet 7072 global</code><br>
|
||||
<code>attr tPort globalpassword mySecret</code><br>
|
||||
<code>attr tPort SSL</code><br>
|
||||
</ul>
|
||||
<br>
|
||||
Note: The old global attribute port is automatically converted to a
|
||||
telnet instance with the name telnetPort. The global allowfrom attibute is
|
||||
lost in this conversion.
|
||||
|
||||
<br><br>
|
||||
Second form, <b>client</b> mode:<br>
|
||||
Connect to the specified server port, and execute commands received from
|
||||
there just like in server mode. This can be used to connect to a fhem
|
||||
instance sitting behind a firewall, when installing exceptions in the
|
||||
firewall is not desired or possible. Note: this client mode supprts SSL,
|
||||
but not IPV6.<br>
|
||||
Example:
|
||||
<ul>
|
||||
Start tcptee first on publicly reachable host outside the firewall.<ul>
|
||||
perl contrib/tcptee.pl --bidi 3000</ul>
|
||||
Configure fhem inside the firewall:<ul>
|
||||
define tClient telnet <tcptee_host>:3000</ul>
|
||||
Connect to the fhem from outside of the firewall:<ul>
|
||||
telnet <tcptee_host> 3000</ul>
