NAME


6tunnel - tunnelling for application that don't speak IPv6

SYNOPSIS


6tunnel [ -146dhfv ] [ -u username ] [ -i password ] [ -I password ] [ -l local_host ] [
-L limit ] [ -p pid_file ] [ -m map_file ] local_port remote_host [ remote_port ]

DESCRIPTION


6tunnel allows you to use services provided by IPv6 hosts with IPv4-only applications and
vice-versa. It can bind to any of your IPv4 (default) or IPv6 addresses and forward all
data to IPv4 or IPv6 (default) host. For example

6tunnel -1 6668 irc6.net 6667

will be enough to connect to IPv6 irc server with

irc foobar localhost:6668

If you don't wish to run 6tunnel every time you want to show your :c001: or :dead: IPv6
address on IRC, you can use -i parameter, which makes 6tunnel ask your client for
specified password. Just run

6tunnel -i dupa.8 31337 irc6.net 6667

and then type

irc foobar localhost:31337:dupa.8

If your IRC server requires you to send password, specify it with -I parameter -- after
successful proxy authentication 6tunnel will send it to the server.

6tunnel can also be used as a tunnel for all other combinations of IPv4 and IPv6
endpoints. If remote host doesn't have any IPv6 addresses, 6tunnel will use the IPv4 one.
In other cases, use -4 parameter which makes IPv4 address the preferred one. For IPv6-to-
any tunnels use -6 which makes 6tunnel bind to IPv6 address.

OPTIONS


-1 Exit after first connection.

-4 Prefer IPv4 endpoint if the machine has both address types.

-6 Listen on IPv6 address (IPv4 is default).

-d Don't detach.

-f Force tunneling even if remote host is not resolvable at the execution time.

-h Print hex dump of every packet received or sent (hu-huh, Beavis, he said hex dump!)

-u username
Change UID and GID after bind().

-i password
Act as an IRC proxy and require user to authenticate.

-I password
If you are using 6tunnel as an IRC proxy and the IRC server requires you to send
password, place it right here.

-l local_host
Listen on specified address (IPv4, or IPv6 if -6 used).

-L limit
Limit simultaneous connections.

-p pid_file
Write down pid to specified file.

-s source_host
Connect to the remote host using specified source address.

-m map_file
Binds to specified IPv6 addresses on basis of source IPv4 address. The file
contains one mapping per line with IPv4 source address and corresponding IPv6
address. Only listed hosts are allowed to connect. If you want to allow any host,
add mapping for default or 0.0.0.0 address. Example:

192.168.0.2 3ffe:8010:18::1000:2
192.168.0.3 3ffe:8010:18::1000:3

-v Be verbose and don't detach.

SIGNALS


Sending SIGHUP forces map file reload.
