Dns2tcp is a tool for relaying TCP connections over DNS. There is only
|
|
a simple identification mecanism but no encryption : DNS encapsulation
|
|
must be considered as an unsecure and anonymous transport
|
|
layer. Resources should be public external services like ssh,
|
|
ssltunnel ...
|
|
|
|
|
|

Available connection(s) :
|
|
ssh-gw

Line based connection to a remote ssl-tunnel host :

|
$ dns2tcpc -r ssl-tunnel -l 4430 -k <my-key> -z dns2tcp._hsc.fr <dns_server>
|

listening on port 4430
