GNS3-server =========== [![image](https://github.com/GNS3/gns3-server/workflows/testing/badge.svg)](https://github.com/GNS3/gns3-server/actions?query=workflow%3Atesting) [![image](https://img.shields.io/pypi/v/gns3-server.svg)](https://pypi.python.org/pypi/gns3-server) [![image](https://snyk.io/test/github/GNS3/gns3-server/badge.svg)](https://snyk.io/test/github/GNS3/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). Branches -------- ### master master is the next stable release, you can test it in your day to day activities. Bug fixes or small improvements pull requests go here. ### 2.x (2.3 for example) Next major release *Never* use this branch for production. Pull requests for major new features go here. Linux ----- GNS3 is perhaps packaged for your distribution: - Gentoo: - Alpine: - NixOS: 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 ``` Finally, these commands will install the server as well as the rest of the dependencies: ``` {.bash} cd gns3-server-master sudo python3 setup.py install gns3server ``` To run tests use: ``` {.bash} py.test -v ``` ### 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) - - 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: and homebrew: . ``` {.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 ``` Security issues --------------- Please contact us using contact form available here:
