Hi Team,

How to add crontab bash script to check when interface is down and it will send mail notification to my mail.

If anyone can help.

Use the job scheduler.

Thanks....

How to verify with CLI that job scheduler is working?

[Danny]

In expert mode just verify with this command: crontab -l

Hey @Danny it shows dummy comamnd.

I know you are master in writing script. 

I have write a bash script can you check it is correct or not?

The script is in file attachment.

Looks like you asked ChatGPT to create those lines for you.

[007_mjn]

haha 

yes, you are right. I got this.

But do I need to setup MTA to get email?

[Danny]

No, this is not required.

[007_mjn]

but there is a problem. I'm not getting email when interface is down.

I think email agent is important.

Hi @Danny 

when I run cron job it shows segmentation failed and generate a core dump.

Then contact TAC (open a SR) to investigate it.
I don't recommend running ChatGPT generated Bash scripts on your gateways.
