SevOne NMS Connect Appliance using Command Line Interface

Summary

As of SevOne NMS 7.0.0, the SevOne NMS software runs in podman containers. If you connect to the NMS appliance using ssh, it will log you on the command line of the NMS appliance host. However, there are additional steps required to connect to the command line interface of the NMS software that runs in a podman container on the NMS appliance.

IBM® SevOne NMS version must be >= 7.0.0.

This article explains the process to connect to the IBM® SevOne NMS container from the Command Line Interface (CLI).

How to Connect to NMS Command Line Interface

Edit online

You may connect to your SevOne NMS appliance via ssh client using the IP address or FQDN of the appliance you want to connect to as a support user. For default support credentials, please refer to SevOne NMS Installation Guide.

There are two options to connect to your SevOne NMS appliance.

Option #1 - via Host to Container
Option # 2 - Directly to Container

via Host to Container

Edit online

Execute the following commands.

Using ssh, connect to your NMS appliance host as support user.
```
$ ssh support@<IP address or FQDN>
```
For example,
```
$ ssh support@SevOne

[support@SevOne ~]$ 
```
On successful login, you are connected to the NMS appliance as the support user at the host level.

Verify the details of the NMS appliance.


[support@SevOne ~]$ cat /config/SevOne.info

base = 7
major = 0
minor = 0

[support@SevOne ~]$

Connect to the Command Line Interface (CLI) of the NMS container.


[support@SevOne ~]$ podman --url=unix:/run/podman_sevone/podman.sock exec -it nms-nms-nms /bin/bash

root@SevOne:/ [7.0.0] [08:00:00] $

Note: For non-root users, you need to specify the socket (unix:/run/podman_sevone/podman.sock) with the --url option to connect to the container.

Directly to Container

Edit online

If you want to connect to the NMS container Command Line Interface (CLI) directly, execute the following command.


$ ssh support@SevOne "podman --url=unix:/run/podman_sevone/podman.sock exec -it nms-nms-nms /bin/bash"

For example,


[support@SevOne ~]$ ssh support@<IP address or FQDN> "podman --url=unix:/run/podman_sevone/podman.sock exec -it nms-nms-nms /bin/bash"

root@SevOne:/ [7.0.0] [08:00:00] $

Now you are connected and logged in to the NMS container as the root user.

Execute the following command to verify the NMS version details.

Note: The output on your system may be slightly different depending on the appliance model, size, and specifications.
