GNS Installation on Fedora 19/18/17

What is GNS3 ?

GNS3 is an open source software that simulate complex networks while being as close as possible from the way real networks perform, all of this without having dedicated network hardware such as routers and switches.


Here are the Steps to install GNS on Fedora 17/18/19:
First of all we need to install the telnet and pyqt4:
Telnet will give us the access console of our network devices:
#yum install telnet pyqt4
Now download the GNS3 form below link:

http://sourceforge.net/projects/gns-3/files/GNS3/0.8.4/GNS3-0.8.4-src.tar.bz2/download

#tar -xjvf GNS3-0.8.4-src.tar.bz2

#cd GNS3-0.8.4-src/

#python2.7 setup.py build

#python2.7 setup.py install 

To emulate Cisco devices, We need dynamipsHere we can download the dynamips:

thanks for Huaren Zhong who is providing this repo.

[rpm-sphere]

name=RPM Sphere

baseurl=http://download.opensuse.org/repositories/home:/zhonghuaren/Fedora_18/

enabled=1

gpgcheck=0



Then install dynamips:
#yum install dynamips 


Now we can launch the gns from user prompt and should follow the instructions for IOS path and dynamips testings. 
#gns3 &
Have done.

Docker Container Management from Cockpit

Cockpit can manage containers via docker. This functionality is present in the Cockpit docker package. Cockpit communicates with docker via its API via the /var/run/docker.sock unix socket. The docker API is root equivalent, and on a properly configured system, only root can access the docker API. If the currently logged in user is not root then Cockpit will try to escalate the user’s privileges via Polkit or sudo before connecting to the socket. Alternatively, we can create a docker Unix group. Anyone in that docker group can then access the docker API, and gain root privileges on the system. [root@rhel8 ~] #  yum install cockpit-docker    -y  Once the package installed then "containers" section would be added in the dashboard and we can manage the containers and images from the console. We can search or pull an image from docker hub just by searching with the keyword like nginx centos.   Once the Image download...

Add The Group Information IN Yum Repository in simple Two steps

= Yum groups and repositories = Yum supports the group commands   * grouplist   * groupinfo   * groupinstall   * groupremove   * groupupdate Groups are read from the "group" xml metadata that is optionally available from each repository.
