The release cycle of NixOs is around every half of the year. On the unstable channel you have the latest gns3-server version. Do not worry to use unstable because it mostly just the latest stable version. You can also do overlays to keep your other systems pkgs on the regular release version.

GNS3-server

===========

|
|
This is the GNS3 server repository.
|
|
|
|
The GNS3 server manages emulators such as Dynamips, VirtualBox or
|
|
Qemu/KVM. Clients like the [GNS3 GUI](https://github.com/GNS3/gns3-gui/)
|
|
and the [GNS3 Web UI](https://github.com/GNS3/gns3-web-ui) control the
|
|
server using an HTTP REST API.
|
|
|
|
Software dependencies
|
|
---------------------
|
|
|
|
In addition of Python dependencies listed in a section below, other
|
|
software may be required, recommended or optional.
|
|
|
|
- [uBridge](https://github.com/GNS3/ubridge/) is required, it
|
|
interconnects the nodes.
|
|
- [Dynamips](https://github.com/GNS3/dynamips/) is required for
|
|
running IOS routers (using real IOS images) as well as the internal
|
|
switches and hubs.
|
|
- [VPCS](https://github.com/GNS3/vpcs/) is recommended, it is a
|
|
builtin node simulating a very simple computer to perform
|
|
connectitivy tests using ping, traceroute etc.
|
|
- Qemu is strongly recommended on Linux, as most node types are based
|
|
on Qemu, for example Cisco IOSv and Arista vEOS.
|
|
- libvirt is recommended (Linux only), as it\'s needed for the NAT
|
|
cloud.
|
|
- Docker is optional (Linux only), some nodes are based on Docker.
|
|
- mtools is recommended to support data transfer to/from QEMU VMs
|
|
using virtual disks.
|
|
- i386-libraries of libc and libcrypto are optional (Linux only), they
|
|
are only needed to run IOU based nodes.
|
|
|
|
### Docker support
|
|
|
|
Docker support needs the script program (bsdutils or
|
|
util-linux package), when running a docker VM and a static
|
|
busybox during installation (python3 setup.py install / pip3 install /
|
|
package creation).
|
|

|
|
- NixOS:

|
<https://search.nixos.org/packages?channel=unstable&from=0&size=50&sort=relevance&type=packages&query=gns3-server>
|
|
|
|
Linux (Debian based)
|
|
--------------------
|
|
|
|
The following instructions have been tested with Ubuntu and Mint. You
|
|
must be connected to the Internet in order to install the dependencies.
|
|
|
|
Dependencies:
|
|
|
|
- Python 3.6, setuptools and the ones listed
|
|
[here](https://github.com/GNS3/gns3-server/blob/master/requirements.txt)
|
|
|
|
The following commands will install some of these dependencies:
|
|
|
|
``` {.bash}
|
|
sudo apt-get install python3-setuptools python3-pip
|
|
```
|
|
|
|
Finally, these commands will install the server as well as the rest of
|
|
the dependencies:
|
|
|
|
``` {.bash}
|
|
cd gns3-server-master
|
|
python3 -m pip install -r requirements.txt
|
|
python3 -m pip install .
|
|
gns3server
|
|
```
|
|
|
|
To run tests use:
|
|
|
|
``` {.bash}
|
|
python3 -m pytest tests
|
|
```
|
|
|
|
### Docker container
|
|
|
|
For development, you can run the GNS3 server in a container
|
|
|
|
``` {.bash}
|
|
bash scripts/docker_dev_server.sh
|
|
```
|
|
|
|
### Run as daemon (Unix only)
|
|
|
|
You will find init sample scripts for various systems inside the init
|
|
directory.
|
|
|
|
Useful options:
|
|
|
|
- `--daemon`: start process as a daemon
|
|
- `--log logfile`: store output in a logfile
|
|
- `--pid pidfile`: store the pid of the running process in a file and
|
|
prevent double execution
|
|
|
|
All init scripts require the creation of a GNS3 user. You can change it
|
|
to another user.
|
|
|
|
``` {.bash}
|
|
sudo adduser gns3
|
|
```
|
|
|
|
upstart
|
|
-------
|
|
|
|
For ubuntu < 15.04
|
|
|
|
You need to copy init/gns3.conf.upstart to /etc/init/gns3.conf
|
|
|
|
``` {.bash}
|
|
sudo chown root /etc/init/gns3.conf
|
|
sudo service gns3 start
|
|
```
|
|
|
|
systemd
|
|
-------
|
|
|
|
You need to copy init/gns3.service.systemd to
|
|
/lib/systemd/system/gns3.service
|
|
|
|
``` {.bash}
|
|
sudo chown root /lib/systemd/system/gns3.service
|
|
sudo systemctl start gns3
|
|
```
|
|
|
|
Windows
|
|
-------
|
|
|
|
Please use our [all-in-one
|
|
installer](https://community.gns3.com/software/download) to install the
|
|
stable build.
|
|
|
|
If you install via source you need to first install:
|
|
|
|
- Python (3.3 or above) - <https://www.python.org/downloads/windows/>
|
|
- Pywin32 - <https://sourceforge.net/projects/pywin32/>
|
|
|
|
Then you can call
|
|
|
|
``` {.bash}
|
|
python setup.py install
|
|
```
|
|
|
|
to install the remaining dependencies.
|
|
|
|
To run the tests, you also need to call
|
|
|
|
``` {.bash}
|
|
pip install pytest pytest-capturelog
|
|
```
|
|
|
|
before actually running the tests with
|
|
|
|
``` {.bash}
|
|
python setup.py test
|
|
```
|
|
|
|
or with
|
|
|
|
``` {.bash}
|
|
py.test -v
|
|
```
|
|
|
|
Mac OS X
|
|
--------
|
|
|
|
Please use our DMG package for a simple installation.
|
|
|
|
If you want to test the current git version or contribute to the
|
|
project, you can follow these instructions with virtualenvwrapper:
|
|
<http://virtualenvwrapper.readthedocs.org/> and homebrew:
|
|
<http://brew.sh/>.
|
|
|
|
``` {.bash}
|
|
brew install python3
|
|
mkvirtualenv gns3-server --python=/usr/local/bin/python3.5
|
|
python3 setup.py install
|
|
gns3server
|
|
```
|
|
|
|
SSL
|
|
---
|
|
|
|
If you want enable SSL support on GNS3 you can generate a self signed
|
|
certificate:
|
|
|
|
``` {.bash}
|
|
bash gns3server/cert_utils/create_cert.sh
|
|
```
|
|
|
|
This command will put the files in \~/.config/GNS3/ssl
|
|
|
|
After you can start the server in SSL mode with:
|
|
|
|
``` {.bash}
|
|
python gns3server/main.py --certfile ~/.config/GNS3/ssl/server.cert --certkey ~/.config/GNS3/ssl/server.key --ssl
|
|
```
|
|
|
|
Or in your gns3\_server.conf by adding in the Server section:
|
|
|
|
``` {.ini}
|
|
[Server]
|
|
certfile=/Users/noplay/.config/GNS3/ssl/server.cert
|
|
certkey=/Users/noplay/.config/GNS3/ssl/server.key
|
|
ssl=True
|
|
```
|
|
|
|
### Running tests
|
|
|
|
Just run:
|
|
|
|
``` {.bash}
|
|
py.test -vv
|
|
```
|
|
|
|
If you want test coverage:
|
|
|
|
``` {.bash}
|
|
py.test --cov-report term-missing --cov=gns3server
|
|
```
