6tunnel - tunnelling for application that don't speak IPv6
6tunnel [ -146dhHfv ] [ -u username ] [ -i password ] [ -I password ] [
-l local_host ] [ -L limit ] [ -p pid_file ] [ -m map_file ] local_port
remote_host [ remote_port ]
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 preffered one. For IPv6-to-any tunnels use -6
which makes 6tunnel bind to IPv6 address.
-1 Exit after first connection.
-4 Preffer 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
-h Print hex dump of every packet received or sent (hu-huh, Beavis,
he said hex dump!)
-H Don't ignore IPv4/IPv6 resolver hints. Original versions allowed
only IPv4 to IPv6 or IPv6 to IPv4 tunnels, so this option revert
Change UID and GID after bind().
Act as an IRC proxy and require user to authenticate.
If you are using 6tunnel as an IRC proxy and the IRC server
requires you to send password, place it right here.
Listen on specified address (IPv4, or IPv6 if -6 used).
Limit simultaneous connections.
Write down pid to specified file.
Connect to the remote host using specified source address.
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:
-v Be verbose and don't detach.
Sending SIGHUP forces map file reload.
#ipv6 crew, Lam.
Terrible man page. Hex dump doesn't include IRC proxy authentication.
IRC proxy requires your client to send password first (don't worry
ircii, EPIC, BitchX, mIRC and many more will work). No logging except
