Unable to determine input ID

Hello,

Thank you very much for writing this utility! I have been using it for some time and it is very helpful.

Recently I am seeing the following error:

I dont know why this is happening. The windows utility is working using the same ip and port without issue.

Would it be possible to add a more verbose explanation of what went wrong in the output message? Any thoughts on why this stopped working?

Oh, a user! :)

Could you please share the output of the following commands?

• bash -x tesmart.sh --debug get-input
• ncat --version

[pschmitt]

and what type of device are you targeting here?

• ncat --version

I'm having the exact same issue, I'm on a raspberry pi 4.

https://gist.github.com/Casuallynoted/a0dd39508a5aa1c16a4a1931ad90bcb6
is the output of the first command, and the second command gives me:
Ncat: Version 7.80 ( https://nmap.org/ncat )

I'm also noticing that I'm getting this error when I try to nc the switch manually:
read(net): Connection reset by peer
If I reset the switch, the error goes away but it quickly comes back.

I'm having a similar issue on MacOS Ventura 13.1 and am running ncat 7.93. Also I noticed that the debug line on 30 and the command on line 33 are using nc which on MacOS is specific to MacOS, so I switched the command to use ncat but gets the same issues as others. I tried this in Ubuntu 22.04 and it works perfectly!

Having the same problem on MacOs.
Let me know if i can help debugging.

[jose-a-rodrigues-alb]

If anyone is interested i was able to make the script work correctly on my mac with macOS monterey, with the changes present on the patch file attached.
macos.patch

@pschmitt Interested in a PR with this changes? not sure if breaks anything on other OSes...

[pschmitt]

Sure, there are already similar PRs open though.

That sleep statement is very odd btw ;)
