Discovery doesn't work if subnet is not /24 #8

Closed KyGunsAndRadio closed 5 months ago

KyGunsAndRadio commented 1 year ago

I normally run printers on a separate subnet configured as 10.10.10.0/25 (255.255.255.128). My client PC is also attached directly to that subnet. But when running sm2uploader, discovery mode would not find my printer. I temporarily changed that subnet to /24 (255.255.255.0) and discovery started working. I'm guessing it's because it's trying to broadcast from 10.10.10.255, which isn't valid on a /25 subnet. Perhaps this is a limitation of UDP discovery?

I was able to use the -host switch and force the IP address, but in that case it didn't identify the printer model. Not sure if that's an issue or not.

Yes, currently it will only broadcast to address 255 under the /24 subnet, which I think is the same as luban. I will test and fix it.

I'v published v2.3, Please let me know if it is resolved.

KyGunsAndRadio commented 1 year ago

Wow, thanks for the quick response! I tried 2.3. This time it seems to be broadcasting on 10.0.0.0 and failed to find anything. I also just tried changing my subnet back to /24, but it did the same thing. Is it possible to determine what the current configured subnet is and set the broadcast accordingly? May be more trouble than it's worth, I doubt too many people are running networks like mine.

Can you post the result of ip addr ?

KyGunsAndRadio commented 5 months ago

I know longer have this particular network config in place, so I can't help support the change. As a result, I closed this issue. If someone in the future should need this, they can re-open or create a new issue.
