ChaosVPN is a VPN to connect Hackers and Hackerspaces - it does NOT provide anonymous internet access!
For this look at tor or other similar services.
It will also not help you to reach domains like .rdos, .lll, .clos or any other strange things supposed to be available on the "dark web".
Alternative: If you prefer BGP, you can also connect via https://dn42.net/, we are interconnected.
- 1 Install software
- 2 Get your new node added to the central configuration
- 3 Enable Starting of ChaosVPN
- 4 Uninstall
The following is written assuming a fresh install of NetBSD 5.2 using the GENERIC kernel, with a pkgsrc repository and networking already configured.
Install necessary programs from pkgsrc
# pkg_add zlib # pkg_add bison (will install m4 as a dependancy) # pkg_add flex # pkg_add openssl # pkg_add gmake
we will also need to install git. Installing git from pkgsrc brings in a long list of other packages (mostly related to Perl) which I list below. If you know a netbsd git client in main that has fewer dependancies, please let me know...
# pkg_add scmgit
adds the following packages as dependancies:
scmgit-base scmgit-docs tcl tk scmgit-gitk perl-5 p5-Error p5-MIME-Base64 p5-TimeDate p5-MailTools p5-Digest-SHA p5-Digest-MD5 p5-Digest-HMAC p5-Net-IP p5-Sockets p5-Net-DNS p5-IO-Socket-INET6 p5-Email-Valid p5-Net-LibIDN p5-Net-SSLeay p5-IO-Socket-SSL p5-Net-SMTP p5-GSSAPI p5-Authen-SASL libffi python27 curl
Create working directories
Create a directory that will story the chaosvpn application. The application will install be default to this location.
# mkdir -p /usr/local/etc/tinc/chaos
Download and Install Tinc
Create a directory to store your tinc source code. This is the directory you will compile tinc from.
# mkdir -p /root/tinc
Download and extract the tinc source. As of this writing the latest stable version available is 1.0.23.
It is available here:
Extract the file in your /root/tinc directory. You can the move into the newly extracted directory containing the tinc source. You can run the following command to configure, build, and install tinc in the appropriate directories under /usr/local :
# ./configure --disable-lzo ; make ; make install
The latest version is also available via pkgsrc.
It’s best to create a new, non-root user specifically for running ChaosVPN. This user will need to be listed in the sudoers file, and will need to be a member of the wheel group, so you can run the
su commands, respectively. In the file
/usr/local/etc/tinc/chaosvpn.conf, change the option $tincd_user to that new user.
Get the ChaosVPN source from the git repository
Always needed to compile:
$ git clone git://github.com/ryd/chaosvpn.git $ cd chaosvpn
The supplied /etc/rc.d/chaosvpn file won't work on netbsd. You'll have to edit it.
Build and Install the application
After editing the makefile, we need to make and install the application.
$ gmake $ su - # gmake bsdinstall
Editing the Configuration Files
Open up /usr/pkg/etc/tinc/chaosvpn.conf using your favorite text editor. Change the following lines:
line 51 $routeadd = "/sbin/route add -net %s $my_vpn_ip -interface \$INTERFACE" needs to change to: $routeadd = "/sbin/route add %s $my_vpn_ip \$INTERFACE -iface "
line 52 $routedel = "/sbin/route delete -net %s $my_vpn_ip -interface \$INTERFACE" needs to change to: $routedel = "/sbin/route delete %s $my_vpn_ip \$INTERFACE -iface "
You may or may not have to edit the path to the PID file to get that to work correctly as well. And now you're good to go. You can follow the rest of the generic chaosvpn configuration information.
Get your new node added to the central configuration
Devise a network-nick and a unique IP range you will be using
This network-nick or sometimes called nodename is the name of the network endpoint/gateway where the vpn software will be running,
not necessarily the name of the user, there may even be more than one gateway per user.
Used below where <nodename> is.
Please use only characters a-z, 0-9 and _ in it. Note that only lowercase letters are supported.
Second please select an unused IPv4 range out of IP Range, and write yourself down in that wiki page to mark your future range as in-use.
Please select from the correct ranges, 172.31.*.* for Europe, and 10.100.*.* for North America and elsewhere.
Repeat: Please do not forget to add yourself to the list at IP Range to mark your range as used.
Used below where <ipv4 subnet in the vpn> is.
The usage of IPv6 networks is also possible, but we do not have a central range for this (yet),
you may specify an IPv6 range you received from your (tunnel) provider to be reachable over the VPN,
or a private IPv6 ULA (Unique Local Address) network described in RFC4193.
For more info about ULA and a network-range generator please also see http://www.sixxs.net/tools/grh/ula/ .
Used below where <ipv6 subnet in the vpn> is.
The gateway may have a DynDNS (or similar) hostname pointing to a dynamic IP, or a static hostname/fixed IP.
Better supply a hostname than a raw IP address even if it is static, so you can change it youself and do not need to contact us when needed. (Perhaps something like chaosvpn.yourdomain.example)
Used below where <clienthost> is.
Generate keys with tinc 1.1+
# tinc --net=chaos init <nodename>
Replace <nodename> with the name your new node should get.
**FIXME** need some way that "tinc init" puts the public key into the seperate files and not only into the generated hosts file, which our chaosvpn daemon overwrites.
generate public/private RSA and ECDSA keypairs with
# tinc --net=chaos generate-keys 2048
press Enter 4 times and backup the files /etc/tinc/chaos/ecdsa_key.priv, ecdsa_key.pub, rsa_key.priv and rsa_key.pub on an external device.
Generate keys with tinc 1.0.xx
create chaos config folder with
# mkdir /etc/tinc/chaos/
generate public/private keypairs with
# tincd --net=chaos --generate-keys=2048
press Enter 2 times and backup the files /etc/tinc/chaos/rsa_key.priv and rsa_key.pub on an external device.

Enable Starting of ChaosVPN
With the latest tinc version I have noticed that when running "chaosvpn -o" for the first time, it will sometimes crash to single-user mode.
I would advise not doing this over the network
You will have to run the following at least one time to update the /usr/local/etc/tinc/chaos/tinc-up and /usr/local/etc/tinc/chaos/tinc-down files with the new structure.
# chaosvpn -o
You will need to run this command when initially setting up the network.
Start the daemon however you want. The /etc/rc.d/chaosvpn that comes by default is not right for a default install of NetBSD. I would recommend removing it.
You may want to use the following in your /etc/rc.d as a template. Its just something I made up for my cvpn router.
Dont forget to run:
# chmod 755 /etc/rc.d/chaosvpn
But why would you want to? :)
rm /etc/rc.d/chaosvpn rm /usr/local/sbin/chaosvpn rm -rf /local/local/etc/tinc/*
Then move the the directory you built tinc in, and run:
