GNS3¶
Getting a console on a router¶
Drag and drop a router onto the working space
Click on the play button (triangle)
Right mouse click on the router -> console
If the setup configruation after the first boot fails or freezes -> Dont panic!
Delete the router
Create a new one
Skip first setup and configure it manually
Configure a Cisco Switch¶
switches must be simulated as a router
cisco catalyst switches must use platform c3600 or c3700
right click on the router -> configure
in the slots tab choose NM-16ESW on slot1
you only be able to start some catalyst images in gns3 (see http://7200emu.hacki.at/viewtopic.php?t=6614)
c3640-is-mz.123-14.T6.bin is known to be working as well
Configuring hosts¶
Install a Qemu Linux (or whatever OS you desire) Image (or download one from http://wiki.qemu.org/Download#QEMU_disk_images)
Goto Edit -> Preferences -> Qemu
Check that the path of qemuwrapper.py is right
Try to execute qemuwrapper.py
If there are errors try to fix them
On Arch linux you have to change python into python2 on the first line of the script
Insert the path to your Qemu image in “Path to quemu-img”
To test or manipulate Qemu images you can either mount it into your filesystem or start it with Qemu
mount -n -o loop <path-to-qemu-image> /mnt
qemu <path-to-qemu-image>
for more information see http://en.wikibooks.org/wiki/QEMU/Images
Use your own Linux system as host os¶
Download the ISO of your Linux distro as distro.iso
Create a qemu harddisk
qemu-img create linux.img 2G
qemu -hda linux.img -cdrom distro.iso -boot -d -m 512
