During my preparation for Juniper JNCIA-Ex , I was looking for JUNOS Simulator to practice ..
my search was very disappointing and i found very few resources but i learned about
Olive (
JUNOS software running on an PC rather than a Juniper router) and i had great experience between the failure and success of trying to install it .
Allow me to share it with you .
First of all...I'd like to thank all ppl over the net who wrote many great articles and blogs about how to install Olive . specially
Himawan Nugroho with the Great Post
Olive is Live which was the center point i move around and which is this blog post is mainly based on , also special thanks for the Software developers and contributors from all those great SW's
qemu,
jqemu,
Kqemu,
OpenVPN,
FileZilla FTP server.
Free BSD ..I love you !!!
and at last ....many many thanks for Juniper for JUNOS
Installation Steps :
*** Downloads****
First do the Downloads and keep your hand full with the bunch of the SW you will need then then begin the Installation process.
A- Download the *qemu programs .
mine are qemu-0.9.1-windows , jqemu , kqemu-1.3.0pre11.tar
u can google for then or simply download them from
here as a single rar file as i did upload them to make it more easy cuz i spent much time looking for sw.
B- Download Free BSD 4.4
mini ISO
as we will Install JUNOS over BSD
if you have no previous experience with Free BSD (like me) ,check this
basic command page,was very helpful.
C- Download OpenVPN
D- Download FileZilla Server
E- Get JUNOS , My version is jinstalll-8.3R2.8-export-signed.
****** Installation *********
Assumption:
- we will Install everything in this directory C:\qemu
- u have basic knowledge of computers , networking and CLI
- u r doing this on your own risk !!!!
1- Install the Qemu --> unzip into directory c:\qemu
2- Install OpenVPN then rename the network interface created during OpenVPN installtion into tap1 , assign an ip Address for it (for example 10.1.1.11/24) and tick on |show icon on notification area when connected | to know what's going during connection your free BSD to your PC
"TAP interface is a virtual interface that can be used by JunOS as fxp interface and allowing us to communicate from Windows OS to Olive over the virtual network."
3- Create your Free BSD Image with 3 Gigs of HDD space with this command
C:\qemu>qemu-img.exe create olive.img -f qcow2 3G
Formating 'olive.img', fmt=qcow2, size=3145728 kB
3- copy Free BSD ISO image to your C:\qemu directoy
4- Boot Free BSD from the ISO with this Command
C:\qemu>qemu.exe -L . -m 256 -hda olive.img -cdrom 4.4-mini.iso -boot d -localtime
qemu is booting from Free BSD Image now .Follow the instructions to Complete the installation.
- Skip Kernel configuration
- Choose standard installation
- With fdisk, press A to allocate entire disk for bsd
- Just select: install a standard MBR
- Create partition (with C):
512M for / partition - create the partition with label ( / ) only
1024M for swap partition
128M for /config
and the rest for /var
- Choose installation type: user, and select No for FreeBSD ports
- X to Exit the menu and install from CD/DVD
- Wait until it's done
Then
- select No No No No No on all the user confirmation requested (Ethernet/SLIP config, gateway, inetd, FTP, NFS, security, console, linux compatibility, set time, etc)
- X to exit the menu
- No for browse FreeBSD package collection and initial user account
- Type root password
- No for chance to set any last options
- Select 'X' to Exit the installation, it will reboot
- while it's rebooting, exit from Qemu by pressing Ctrl-Alt-2, then type: quit
5- Install FileZilla FTP Server and put JUNOS image in the shared Folder
6- Start qemu using jqemu, with options to include i82559er as nic type, assigned mac-address and map the nic to interface name Tap1:
C:/qemu>jqemu.exe -L . -m 256 -hda Olive.img -localtime -net nic,vlan=1,macaddr=00:aa:00:00:01:01,model=i82559er -net tap,vlan=1,ifname=Tap1
7- Connectivity test
- login to the FreeBSD with the root account and password we set during the installation
- setup the IP address
#ifconfig fxp0 up 10.1.1.22
- try to ping 10.1.1.12 from FreeBSD
and note connected icon in the notification area
8- FTP Transfer
#cd /var/tmp
#ftp 10.1.1.11
then >ftp : binary (to be in binary mode)
>ftp : get (the jinstall file)
now you the JUNOS on Free BSD virtual HDD
9- Modify the Jinstall file
JunOS image after 7.4 version has a binary called checkpic. This binary will fail and the image cannot be installed. Replacing this binary with /usr/bin/true fixes the issue.
We need to untar the signed jinstall file first:
#cd /var/tmp
#mkdir jinst-signed
#cd jinst-signed
#tar zxvf ../jinstall-8.3R2.8-export-signed.tgz
Then untar the unsigned image:
#mkdir jinst
#cd jinst
#tar zxvf ../jinstall-8.3R2.8-export.tgz
Extract the pkgtools.tgz file and replace the checkpic binary inside with /usr/bin/true :
#mkdir pkgtools
#cd pkgtools
#tar zxvf ../pkgtools.tgz
#cd bin
#cp /usr/bin/true ./checkpic
#cd ..
Create tar for pkgtools then remove the directory:
#tar zcvf ../pkgtools.tgz * (space between tgz and *)
#cd ..
#rm -rf pkgtools
Create tar for the new jinstall package with modified checkpic
#tar zcfv /var/tmp/jinstall-8.3R2.8-export-olive.tgz * (space between tgz and *)
10 -install the new jinstall with bsd pkg_add tool:
#pkg_add /var/tmp/jinstall-8.3R2.8-export-olive.tgz (i used Force switch to be able to install as i was getting warning messeges and the installtion stops )
It will ask to reboot to continue the installation.
#reboot
When it's rebooting, press Ctrl-Alt-2 and type: quit.
11- Me , My self and Olive
The default behavior from JunOS won't allow us to login to it from the standard output and we must use serial console instead. So start Qemu again using Jqemu.exe and this time put the option to redirect the output to serial port emulated by local TCP port 1001.
C:\qemu>jqemu.exe -L . -m 256 -hda Olive.img -serial telnet::1001,server -localtime -net nic,vlan=1,macaddr=00:aa:00:00:01:01,model=i82559er -net tap,vlan=1,ifname=Tap1
Qemu windows will pop up and it's waiting for TCP connection to port 1001.
Open another Windows DOS prompt and telnet 127.0.0.1 1001.
We can see the whole installation process until it reboots when it's done.
After JunOS installation is complete we can login to Olive for the first time with root account and no password.
root@%cli
root>edit
[edit]
root#
Create password for the root account, then set the IP address
[edit]
root#set system root-authentication plain-text-password
New password:
Retype new password:
[edit]
root#set interface fxp0 unit 0 family inet address 10.1.1.22/24
[edit]
root#commit
commit complete
If everything is set up properly, we should have connectivity from Olive from fxp0 interface to Windows Tap 1 interface.
11. Login to Olive for the first time!

After JunOS installation is complete we can login to Olive for the first time with root account and no password.
From BSD prompt, type 'cli' to go to JunOS prompt, then assign the IP address 10.1.1.22/24 to fxp0
root@%cli
root>edit
[edit]
root#
Create password for the root account, then set the IP address
[edit]
root#set system root-authentication plain-text-password

[edit]
root#commit
commit complete
If everything is set up properly, we should have connectivity from Olive from fxp0 interface to Windows Tap 1 interface.
Later we can install Kqemu to improve the performance:
- download kqemu from
here, and extract it to a folder.
- Go to that folder, then the kqemu folder within it, and right click on kqemu.inf, and select install.
- from windows prompt type 'net start kqemu'
C:\>net start kqemu
The KQEMU virtualisation module for QEMU service was started successfully.
Now we can start Olive using Jqemu with additional kernel-kqemu option:
C:\qemu>jqemu.exe -L . -m 256 -hda Olive.img -serial telnet::1001,server -kernel-kqemu -localtime -net nic,vlan=1,macaddr=00:aa:00:00:01:01,model=i82559er -net tap,vlan=1,ifname=Tap1

and now JUNOS Olive Machine is Up and Running ..
