(Tutorial) How To Install GNS3 on Centos/Redhat/Fedora .
You won't find detailed instructions for GNS3 installation on Centos/Redhat/Fedora over the net, So I decided to make one for our certcollection members. Installing GNS3 on Centos/Redhat/Fedora can be very tedious task. But If you follow my Steps given below you can setup and run GNS3 without any difficulty. Since Qt 4.5.1 binary which is required for GNS3 is not available for these OS's, we'll have to compile it from the source.
OK lets roll
First we'll have to install dependencies
[user@admin ~]$ su
Password: (Type in your root password here)
[root@admin /]# yum install python python-devel xorg-x11-proto-devel libXext-devel
[root@admin /]# yum install gcc-c++
Now we'll download and install Qt4
[root@admin /]#cd /tmp
[root@admin tmp#wget ftp://ftp.qt.nokia.com/qt/source/qt-x11-opensource-src-4.5.1.tar.gz
[root@admin tmp]#tar xzf qt-x11-opensource-src-4.5.1.tar.gz
[root@admin tmp]# cd qt-x11-opensource-src-4.5.1
[root@admin qt-x11-opensource-src-4.5.1]#./configure -nomake examples -nomake demos -qt-gif -no-exceptions -debug -qt3support
[root@admin qt-x11-opensource-src-4.5.1]#gmake <====This might take 2-3 hrs.
[root@admin qt-x11-opensource-src-4.5.1]#gmake install <====Another 30 mins or so
[root@admin qt-x11-opensource-src-4.5.1]#PATH=/usr/local/Trolltech/Qt-4.5.1/bin:$PATH
[root@admin qt-x11-opensource-src-4.5.1]#export PATH
Next we'll install SIP
[root@admin qt-x11-opensource-src-4.5.1]#cd ..
[root@admin tmp]#wget http://code.enthought.com/src/sip-4.8.1.tar.gz
[root@admin tmp]#tar xzf sip-4.8.1.tar.gz
[root@admin tmp]#cd sip-4.8.1
[root@admin sip-4.8.1]#python configure.py
[root@admin sip-4.8.1]#make
[root@admin sip-4.8.1]#make install
Next we'll Install PyQt4
[root@admin sip-4.8.1]#cd ..
[root@admin tmp]#wget http://ftp.pardus.org.tr/pub/source/2009/PyQt-x11-gpl-4.5.2.tar.gz
[root@admin tmp]#tar xzf PyQt-x11-gpl-4.5.2.tar.gz
[root@admin tmp]#cd PyQt-x11-gpl-4.5.2
[root@admin PyQt-x11-gpl-4.5.2]#python configure.py
[root@admin PyQt-x11-gpl-4.5.2]#make <=====This will take 30-60 mins
[root@admin PyQt-x11-gpl-4.5.2]#make install
We are done with compiling part, now lets download GNS3 source files
[root@admin tmp]#cd /opt
[root@admin opt]#wget http://nchc.dl.sourceforge.net/project/gns-3/GNS3/0.7.4/GNS3-0.7.4-src.tar.bz2
[root@admin opt]#tar -xjvf GNS3-0.7.4-src.tar.bz2 && rm GNS3-0.7.4-src.tar.bz2
[root@admin opt]#mv GNS3-0.7.4-src /opt/GNS3
Create the following directories:
These directories will be used by GNS3 – such as projects – where your working projects will be stored, cache, temp, IOS images, etc.
[root@admin opt]#cd /opt/GNS3
[root@admin GNS3]#mkdir Dynamips
[root@admin GNS3]#mkdir IOS
[root@admin GNS3]#mkdir Project
[root@admin GNS3]#mkdir Cache
[root@admin GNS3]#mkdir tmp
[root@admin GNS3]#chmod o+rw -R ./Project
[root@admin GNS3]#chmod o+rw -R ./tmp
[root@admin GNS3]#chmod o+rw -R ./IOS
Download binary of dynamips and make it executable
[root@admin GNS3]#cd Dynamips
[root@admin Dynamips ]#wget http://www.opendrive.com/files/25226584_Cmocn_9400/dynamips-0.2.8-RC3-x86.bin
[root@admin Dynamips ]#chmod +x ./dynamips-0.2.8-RC3-x86.bin
IMP:: For 64-bit users (I don't have Dynamips 0.2.8 RC3 for 64 bit, if you have it please share it with me)
[root@admin Dynamips ]#wget http://www.ipflow.utc.fr/dynamips/dynamips-0.2.8-RC2-amd64.bin
[root@admin Dynamips ]#chmod +x ./dynamips-0.2.8-RC2-amd64.bin
You can create a desktop shortcut by right-clicking on the desktop and select “Create Launcher..”, Name it GNS3 and in the command section type in
python "/opt/GNS3/gns3"
Double click to open GNS3 and we will edit the default settings. If you don’t want to use desktop icons you can create a launcher from your programs menu by right clicking on the Main Menu, selecting Edit Menu. Select New Item on the right and you will be presented with the same window where you type in the above. From there you can move the launcher into any menu section of your choice.
Fire up GNS3
* Go to edit | preferences and in the ‘Terminal command:’ section type in:
gnome-terminal -t %d -e 'telnet %h %p' > /dev/null 2>&1 &
* Under ‘Paths’ change the ‘Project directory:’ to
/opt/GNS3/Project
and the ‘IOS/PIX directory:’ to
/opt/GNS3/IOS
* Click on Dynamips tab on the left
For the ‘Executable path:’ type in
/opt/GNS3/Dynamips/dynamips-0.2.8-RC3-x86.bin
* Change the ‘Working directory:’ to
/opt/GNS3/tmp
Click on the Capture tab on the left
* For the ‘Working directory for capture files:’ change it to
/opt/GNS3/Project
Imp:: When you want to stop the router, use right click stop on the router.
After you have done all that, you will be able to Open and Save your GNS3 projects properly and have an efficient setup for GNS3. In order to use the devices in GNS3 you must obtain our own IOS images from Cisco or http://networkingtips-tricks.blogspot.com/2010/03/cisco-ios-collection-for-gns3-and.html

[root@admin /]#wget http://www.python.org/ftp/python/2.6.6/Python-2.6.6.tgz tar -zxvf Python-2.6.6.tgz cd Python-2.6.6 ./config && make && make install
Add the install path (/usr/local/bin/python : by default) to ~/.bash_profile as follow :
PATH=$PATH:$HOME/bin:/usr/local/bin/python2.6
Now follow the steps given at the top page,
Change python configure.py to python2.6 configure.py under Next we'll install SIP and Next we'll Install PyQt4.
Hope this tutorial will help you guys to setup and run GNS3 on your Linux system.

68 Respones to "(Tutorial) How To Install GNS3 on Centos/Redhat/Fedora ."
hi naresh,
thanks for the guidance above, but i got a small problem and hopefully you can help me.
i'm using centos as well and followed your instruction exactly without any errors.
i'm able to run gns3 but the problem is I always got "failed to start Dynamips" when i clicked the Test button on GNS3's Dynamips.
fyi, if i run dynamips manually from CLI ($ dynamips -H 7200), it worked.
any idea how to solve this problem? I couldn't find any similar solution from google/hacki, mostly for windows and it's only the path problem but i'm hundred percent sure that the path is correct and also the permission is open/granted for the user.
thanks in advance
September 20, 2010 at 10:39 PM
Please recall if you had made dynamips executable by executing this command chmod +x ./dynamips-0.2.8-RC2-x86.bin, if not do it now. Also try running gns3 as root. If you still face problem please let me know.
September 20, 2010 at 11:25 PM
Hi,
This is the most accurate tutorial that I have seen on this subject.
Just want to know if somebody have seen this error when installing on Centos 5.5
[root@samba PyQt-x11-gpl-4.5.2]# python configure.py
Determining the layout of your Qt installation...
Error: Make sure you have a working Qt v4 qmake on your PATH or use the -q
argument to explicitly specify a working Qt v4 qmake.
Does somebody knows how to fix this?
Thanks

September 21, 2010 at 12:58 AM
hi cyberwiz,
yes i did that (chmod +x), here's the list:
[root@zimbra Dynamips]# ls -l
total 928
-rwxr-xr-x 1 tara users 943340 Sep 20 23:29 dynamips-0.2.8-RC2-x86.bin
i also tried running gns3 as root but still got the "failed to start dynamips" status.
if i directly drag the c3600 icon, i got this error: "Can't connect to the hypervisor on port 7200: (-2, 'Name or service not known')". is that error because the dynamips failed to run?
thank u, appreciate your help.
September 21, 2010 at 4:45 AM
Yes this error relates to dynamips, Please check If you are using centos 64 bit, if yes, you'll need http://www.ipflow.utc.fr/dynamips/dynamips-0.2.8-RC2-amd64.bin. Also try disabling selinux and firewall before running gns3. One more solution is to check that you don't have multiple python installed by running rpm -qa | grep python, if so uninstall the older version. If you still have face problem please let me know.
September 21, 2010 at 10:37 AM
Mate, if you are getting that error, you haven't followed my steps properly, You'll need qt-x11-opensource-src-4.5.1 package. Please check the installation steps under the heading Now we'll download and install Qt4. If you still face any problem let me know.
September 21, 2010 at 10:42 AM

Superb Dude...I just did it without knowing anything...Awesome Job..
November 25, 2010 at 10:36 AM
robtech,
I don't know about working as root.But as a user,make sure that the
1.project directory
2.tmp directory
3.Dynamips directory
has permissions to access the directories..Change the owner to user instead of root.It may work.

Thank You, YOU ARE AWSOOOME =D it worked perfectly only small problem though: I get error dynamips error:206-unable to extract config from VM "R1". I don't think it will be to mych of a prob to solve I'll try to work my way around it,but if u can help on this one too it would be great.
thanks again for updating links, I'll be praising ur name for years to come =))) thanks a lot
February 26, 2011 at 8:04 PM
Already fixed the problem with Dynamips error: unable to extract config. I just needed to config the baseconfig.txt file in IOS config. You just need to make shure that file exsits at all u can leave it empty or put some config. for example:
!privilege level 15 ( if u'r too lasy to type enable all the time router starts =)) )

hi again, =))) me with my problems. Although I did try my best to work out this on my own I FAILED. anyways.
GNS3 works perfect, I have ASA (Qemu if i get lucky) and crapload of routers ( like 15 or so ) anyway. after I complete my work I save. and after I restart GNS3 and try to load, it fails. With dynamips erroe message that
Following errors occured: (and the space here indicates nothng, it's empty . no errors.)
every time I start GNS3 I have to go in options and press Test to start dynamips and Qemu, otherwise nothing works. I have no problem doing that but I do have problem with my project not loading.
Once again I place my hopes with u =)) currently I am back on windows. no similar problem there but hell it can barely load 3 routers without lagging. and the CPU flies sky-high.

Try starting GNS3 as a root.
March 9, 2011 at 11:01 AM
Dear,
I'm using CentOS 2.6.18-194.32.1.el5xen and I went through all steps (Seems OK). However, I can't start GNS3 by "/opt/GNS3/gns3". It warmed me the message as below:
******************************************
[root@localhost ~]# python "/opt/GNS3/gns3"
Traceback (most recent call last):
File "/opt/GNS3/gns3", line 41, in ?
raise RuntimeError, "Need Python 2.6 or higher"
RuntimeError: Need Python 2.6 or higher
*******************************************
And here is the installed python package version (From yum install python)
*******************************************
Installed Packages
Name : python
Arch : x86_64
Version : 2.4.3
Release : 27.el5_5.3
Size : 21 M
Repo : installed
****************************************
What should I do? I tried to upgrade the python version by "yum update python", but there is no update.
Please help! Many Thanks!

Try anyone of the given links

http://blog.boxedice.com/2010/01/19/updating-python-on-rhelcentos/
March 10, 2011 at 6:55 PM
Right way to do it.
wget http://www.python.org/ftp/python/2.6.6/Python-2.6.6.tgz tar -zxvf Python-2.6.6.tgz cd Python-2.6.6 ./config && make && make install
Add the install path (/usr/local/bin/python : by default) to ~/.bash_profile
It will not break yum or any other things which are dependent on python24.
Next follow my tutorial again , I have provided new links. Don't mix it with qt everywhere package. Apply my steps as it is.

I follow the instructions ... but I got the error:
Can't import Qt modules, PyQt is probably not installed ...
Pls Help ....

re: the Right way to install python 2.6:
Apologies, but I'm having trouble getting past the PyQt not found.
Centos 5.5 on an AMD64 box
I've compiled python 2.6.6 using ./configure && make && make install
question, does the make need an altinstall option?
>> Add the install path (/usr/local/bin/python : by default) to ~/.bash_profile
/usr/local/bin/python is the python 2.6.6 executable. How does this go in the path?
>> Don't mix it with qt everywhere package
I'm not sure what this means?
Thank you.

Installing GNS3 on a VM CentOS 5.6
Followed the tutorial step by step and everything went fine.
Couldn't fire GNS3 by double clicking the shortcut created.
In CLI python /opt/GNS3/gns3 gives me the error message:
"Traceback (most recent call last):
File "/opt/GNS3/gns3", line 41, in ?
raise RuntimeError, "Need Python 2.6 or higher"
RuntimeError: Need Python 2.6 or higher"
Added python 2.6 as you suggested got the error:
"[root@localhost ~]# python2.6 /opt/GNS3/gns3
Can't import Qt modules, PyQt is probably not installed ...".
Tried to follow your tutorial again but don't know where to start.
any help would be much appreciated.

please help me when trying to install sip on fedora 14 it gives me a timeout error because cvs.fedoraproject.org has been taken down, where else can i look for it ??? thanks in advance
May 1, 2011 at 5:50 PM
Done. New links added.
May 1, 2011 at 11:14 PM
Hi. I've installed a fresh Centos 5.5. The PyQt4 4.5.2 is no longer available. I have found a later version at riverbankcomputing (4.8.3) but this required a later version of SIP also. I installed 4.12.1 of SIP. Installed GNS3 but now when I go to start GNS3 it requires Python 2.6 or greater. I've installed Python 2.6 but when I run GNS3 with Python 2.6 I get 'Can't import Qt modules, PyQt is probably not installed ...'
Does anyone have fresh install instructions to get GNS3 loaded on Centos 5.5 (or 5.6)?
May 2, 2011 at 4:42 PM
Naresh, where are the updated steps? the links in the steps above no longer work. i have found new packages at riverbankcomputing but haven't got the install to work correctly yet. any help would be very much appreciated.
May 2, 2011 at 5:18 PM
Please check the tutorial again, I've updated it with new links and steps to install python 2.6 is also added at the end of the tutorial.

Hi Naresh, thanks for the updated comments. I've installed a fresh Centos 5.6 and followed your steps. The ./confg for Python didn't seem to work. I installed Python 2.6 a different way but when doing the make in SIP i get;
siplib.c:9189: error: expected ')' before '*' token
If I use Python 2.4 there is no issue.

Great post. One note: CentOS 5.4 installs only support glibc2.5, while dynamips_0.2.8RC3 requires glibc2_7. You can't easily upgrade glibc, and although hacking some soft links may work (i've been known to do that in a pinch), i'd recommend just using dynamips_0.2.7 instead.

hey.. everything went fine but after the installation.. when i hit test at the Dynamips tab...it says "Failed to start Dynamips"

June 15, 2011 at 7:19 AM
Please help!
I keep on getting the error mseeage " working directory seems to not exist or be witable, please check
i check it is writable
i ran it as root same thing
July 1, 2011 at 3:03 AM
Great post. Just so you know though, the extra steps are no longer required for CentOS 6 (or RHEL 6), correct version of Python is in the repositories so everything installs fine. Might want to update your "Update for CentOS" to be "Update for CentOS 5.X"
Again thanks for the post!

Great !
I've installed CENT OS6, it's already had Python 2.6, and I have no problems at all.
Thanks a lot.
P/s: if you have Dynamips 64bits version, please share !

Does the python2.6 issue also apply to Redhat 5.8
I tried on Redhat 5.8 which has python2.4 but it doesn't work
I tried installing on Redhat 6.3 with python 2.6 but on 6.3 gmake fails for qt4.
Did anybody had luck following these instructions on Redhat 5.x or Redhat 6.3?
