Of course, mom.

# Sample tinc configuration file

# This is a comment.
# Spaces and tabs are eliminated.

# Variable names are treated case insensitive.

Name = zomb

# The internet host to connect with
# comment these out to make yourself a listen-only connection
# You may use an IP address or its FQDN.

#ConnectTo = home

# Connect to which port of the `ConnectTo' host

# It is advised that you only connect to ports that are < 1024,
# because some malicious (non-root) user may run a fake tincd on ports
# above 1024.
# The default port is 655, the port that has been assigned to tinc
# by the IANA. If you want tincd to listen on any other port than 655,
# you can use ListenPort for the `server', and ConnectPort for the
# `client'.

# You may use the prefixes 0x or 0 to denote a hexadecimal or octal
# number respectively.
#ConnectPort = 0x300
#ConnectPort = 655

# Listen on which port
#ListenPort = 655
#

# My own VPN IP
# You may use the /nn notation to indicate the number of bits used for
# the mask, /8 is equivalent to the netmask 255.0.0.0 (the first 8
# bits are set to 1).

InterfaceIP = 0.0.0.0/0

# VPN Netmask
# You'll need this option if you use the Debian or Redhat init
# scripts.  Put in here a netmask that covers your entire VPN network;
# it is used to set routes from the init script, tinc itself ignores
# it.
# VpnMask = 255.255.255.0

# Which local file?
# Default is /dev/tap0
TapDevice = /dev/tap0

IndirectData = yes

PrivateKey = 3D22D154529E47366464F303DA67504CDDE2B331C3C8F8341A4C83CCC6075B14F50B1768A97E9B2EC34E868F2206FC1AF77BFE9DD42FEA8A02507C27B4F63ACAF1991FE746CCBA73F081433F17F1C3D409C6077E02EB55271428F36C0C970034BC3807517A171A034D27DC5701C3773C1959B593C516BA942134DFAF17600547

The key is changed so it won't help you on cracking my box ;)

--- /etc/tinc/vpn/hosts/zomb.pub ---

The keys are generated using "tincd -K" and pasted to mentioned files.

MfG,
Eduard.
