Add ability for kathara exec to return same status code as executed command about kathara

[tcaiazzi]

Hi @Thomas-McKanna,

Thanks for reaching out! We are super happy you like the tool!

My feature suggestion is to add a flag or make it the default behavior such that kathara exec returns the same status code as the command which was executed on the device

Yes, I agree with you, this is an interesting suggestion, and we will consider it in the future developments.

If there is another preferred way to check lab configurations, this would be good to put in the wiki. But I wasn't able to find any content about it.

Actually, we developed a tool to automatically check labs by configuring a json file (I was boring to do it manually). We used it to grade students during this year, but probably it is not ready for the publication since it lacks of some documentation.

Basically, the tool can check:

• Device's existence and reachability;
• Devices' routing tables;
• Daemon process on devices;
• Interface configurations (ipv4 and ipv6);
• bridge configurations on device;
• DNS configurations
• BGP (or EVPN BGP) configurations (we use it for checking data center scenarios)

We missed many checks, especially on IGPs, but I will implement them for the next year's exams. I tried to make the tool as modular as possible, to facilitate integrations.

The repository contains an example to run, but probably it is not updated with all the possible checks.

You can find it here: https://github.com/tcaiazzi/kathara-lab-checker/tree/main

Please let me know if you can use it (if you have time to try 😇), and do not hesitate to open issues or discussion there (especially on the types of checks you need).

I have a deadline in the following weeks, but as I find some time, I can try to write some documentation or to help you with using the lab-checker.

Anyway, we will also consider your suggestion on the exec command.

Thanks!

@tcaiazzi Thank you for the quick reply! The repository you linked to looks like it will work well for my needs. I'll be taking a closer look at it in the week to come. Thanks!
