Warning
I strongly advise against redistributing the package resulting from this APKBUILD. The resulting package is a bundle of various pieces of software with different licenses. Because of this, the only way to ensure no license is being violated is to use this APKBUILD and the resulting package for personal use only.
This APKBUILD can be used to generate a .apk package for Alpine Linux containing GNS3-server with all of its Python dependencies bundled in (using the versions recommended by upstream GNS3-server).
The package also creates a gns3 user and group to run the server under.
The server can be easily managed using an included OpenRC init script.
Ensure your Alpine Linux system is configured to build packages using abuild. If you have not done this already, a basic setup can be achieved using the following:
doas apk add alpine-sdk
doas addgroup <user> abuild
# re-log or reboot
abuild-keygen -ai
Now you may use the contents of this repo to generate the desired package:
git clone https://github.com/rwinkhart/gns3-server-portable-APKBUILD.git
cd gns3-server-portable-APKBUILD
abuild -r
The resulting package will be placed at ~/packages/home/x86_64/gns3-server-portable-<version>.apk
It can be installed with doas apk add </path/to/.apk>.
If installing on a system not configured to trust your abuild key, you will need to specify --allow-untrusted at the end of the above installation command.
By default, the GNS3 "cloud" node cannot be used to bridge your virtual network to physical interfaces. This is because GNS3 cannot create the needed taps for the direct physical interfaces. Instead, each physical NIC needs to be set as a member of a bridge interface.
This can be done in /etc/network/interfaces as follows (for each desired interface):
auto gns-eth0-br
iface gns-eth0-br inet manual
bridge_ports eth0
bridge_stp off
bridge_fd 0
bridge_maxwait 0
auto eth0
iface eth0 inet manual
Also ensure the
tunkernel module is loaded, otherwise GNS3 will throw an error stating "unable to create NIO TAP for bridge".
After rebooting, connect to the new virtual bridge interface from the "cloud" node to connect over your physical interface.
