The post Intent-based Networking explained appeared first on Noction.
One of my readers sent me an interestingly sad story as a response to my importance of fundamentals rant. Here it is… enjoy ;)

Rival Viavi viewed as a possible merger partner.
“We have a cloud and they have a network.”
The partnership deploys VNFs on Juniper's branch routers.
Is networking becoming a commodity? Do we all need to worry about losing our jobs as network engineers because no-one cares about how a commodity is created or provided? Maybe it is time to take a second look at the commodity craze.
In certain situations, I need to connect to a remote network via a bastion host but only have SSH available to me. To get around installing some kind of VPN gateway, the easiest thing to do is to create an SSH tunnel.
In this situation, what happens is that you set up local port-forwarding. Local port numbers are forwarded to the remote host via an SSH tunnel to the intermediate host.
The command format to do this on OSX is:
ssh -C -L <LOCAL-PORT>:<REMOTE-IP>:<REMOTE-PORT> <USERNAME>@<BASTION-HOST>
So for example, I can forward local port 1000 on my Mac to the remote device’s port 23 using this command (sudo has to be used for local ports lower than 1024):
sudo ssh -C -L 1000:10.200.0.1:23 [email protected]
Once authenticated, I can open another terminal window and type:
telnet localhost 1000
and hey-presto, I get connected to a remote router via telnet through an encrypted SSH tunnel! The -C parameter is for compression and isn’t actually necessary.
If you need to create a number of local port-forwards, this can be done in a config file instead. By default SSH reads /etc/ssh/sshd_config for system-wide parameters, and also Continue reading
