Upgrade GNS3 from 0.7.2 to 0.7.3 on Ubuntu

If you are still running GNS3 0.7.2 it’s a good idea to upgrade towards GNS 0.7.3. I haven’t tested all of the features yet but so far there 2 things that i like:

• The new etherswitch…I have no idea if it adds something compared to the old C3460 with NM16-SW switch but the new icon looks cool 🙂
• I managed to install the ASA8 within 5 minutes!

If you are running Ubuntu this is the fastest way to upgrade from 0.7.2 to 0.7.3: (Thanks to a post from Rednectar on the GNS3.net forum)

• cd /opt (if this is the folder where you installed GNS3)
• sudo wget http://downloads.sourceforge.net/gns-3/GNS3-0.7.3-src.tar.bz2
• sudo tar -xjvf GNS3-0.7.3-src.tar.bz2
• sudo rm GNS3-0.7.3-src.tar.bz2
• sudo rm -fr GNS3/docs
• sudo rm -fr GNS3/qemuwrapper/
• sudo rm -fr GNS3/src
• sudo mv GNS3-0.7.3-src/* /opt/GNS3
• sudo rm -fr GNS3-0.7.3-src/

Just to be sure, change the owner to your username. Otherwise root will be the owner:

• cd /opt (or another folder where you installed GNS3)
• sudo chown -R username GNS3

That’s it! Have fun with the new GNS3 version…if you find any new features please share by leaving a comment!
