The first command starts the ssh-agent process. Here is the process to start up the ssh-agent manually and add your eval ssh-add jeremykey Depending on your system, the ssh-agent might be running already. In order for ssh-keys to work, you need to have an "ssh-agent" running and then add your keys to the agent. On , I create an SSH config file in $HOME/.ssh/config that looks like the following. The following illustrates the mapping I want to create: I can pick any ports that I want, but generally in the range above the range 1024. The technique for ssh-port forwarding is to designate ports on that get mapped to specific hosts reachable from . Set Up "Jeremy-PC" for SSH Port Forwarding To do this, I need to edit the SSH config file in $HOME/.ssh/config so that it looks like this: I now need to set up my user account on so that it will forward my SSH connections when I originate them from my laptop,.
#Port forward network utilities keygen install#
Assuming that I've copied the file jeremykey.pub to each Junos OS device, I can install the key from the Junos OS CLI for example, on the SRX3600-1 configureĢĞntering configuration set system login user jeremy authentication load-key-file commit and-quit You will need to first copy them to your jump-host, and then from there scp them to each Junos OS device. Now copy your public key file to each of the Junos OS devices.

Install the Public ssh-key onto Junos OS Devices You will be prompted to enter a passphrase, which I recommend you ssh-keygen -f jeremykeyģ Generating public/private rsa key pair.ĤĞnter passphrase (empty for no passphrase):Ħ Your identification has been saved in jeremykey.ħ Your public key has been saved in jeremykey.pub. Here I am creating a pair called "jeremykey" (private key) and "jeremykey.pub" (public key). Use the ssh-keygen command to create the public and private keys. If you are not familiar with the process of generating ssh-keys, it is fairly straightforward, provided you have the SSH utilities installed. Activate SSH tunnel and ssh-key from, then connect!.Set up my user account on to ssh-port tunnel.Set up my user account on to allow SSH forwarding.Install the public ssh-key on the Junos OS devices, srx3600-1, mx960-1, and mx960-2.In order to make all this work, I need to do the following: In order for my Python programs to connect from jeremy-pc to the SRX and MX Series, I need to go through jumpy, I cannot ssh directly to them (which means I cannot open a NETCONF session directly either).
#Port forward network utilities keygen series#
Behind "jumpy" I've got a few hundred EX Series switches, a few SRX firewalls, and a few MX Series routers: All of the network devices are in the private 10.1.0.0/16 network. Take for example the following setup: I have a laptop called and a jump-host called . This means you need to first log in to the jump-host, and from there you can access the devices. Let's say you have a network of devices that are behind a firewall and you can only access them through a jump-host. Junos OS NETCONF and SSH Tunneling (Part 1)
