The easiest and quickest way to install JNOS 2.0 on a linux system is to use the JNOS 2.0 installer program. In my opinion, this is an excellent way for people to get introduced to JNOS 2.0. It is great for people who have never used JNOS 2.0 before, or are still struggling to get something to work for them. NOW - the installer is very simplistic, and so is the configuration generated. The idea is to start off as simple as you can, then build on the configuration as your experience with JNOS 2.0 grows. There is nothing stopping even the most experienced people from using the installer. The installer is text based, no graphics libs are required.

What Are You Given


You will need an installer package (installerv2.1.tar.gz) - click here to get one.


After downloading the file above, login as root, and run the following commands in the order listed :
  cd /tmp
  gunzip installerv2.1.tar.gz
  tar xvf installerv2.1.tar
  cd installerv2.1
Just answer the questions as they come. When finished, keep in mind that JNOS has to be run as the ROOT user if you want network connectivity. The installer will give you some usages hints at the end. The JNOS program (executable, binary) that comes with the installer is not necessarily the latest version, and may not be compiled with all the options you want. If that is the case, you could try and compile your own flavour (which is what alot of people wind up doing anyway).

Network connectivity

Keep in mind that network connectivity requires the tun kernel module. Most systems have it loaded by default.

Also, the autoexec.nos generated by the installer makes a shell call to the linux ifconfig command. If you look at the autoexec.nos, you will see there is no full path to this command, the system assumes that ifconfig will be in the root path. Keep that in mind, just incase the shell fails to find it.
