Hello,

I hope to get some help with this.

let's have a look at the config file.

Thank you for your reply, psherman!

Just started preparing the config files and gave them another look...
Removed the mask and it worked.
No idea why I'd put it there...

/etc/config/nut_server

config driver 'CP1500PFCLCDa'
        option driver 'usbhid-ups'
        option port 'auto'
        option product 'CP1500PFCLCDa'

config user
        option username 'ups-admin'
        option password '***'
        option upsmon 'master'

config listen_address
        option address '0.0.0.0/0'  <--WRONG
        option port '3493'

@jhs

config listen_address
        option address '0.0.0.0/0'  <--WRONG
        option port '3493'

just make it 0.0.0.0 (remove the /0). Then try starting the service again.

Yes, exactly what I mentioned.

Thank you for the super-fast replies!!!

Yes, exactly what I mentioned.

Sorry, I hadn't noticed that you had mentioend it already... I just looked at the file and saw the error.

the reason why is that 0.0.0.0 basically says "listen on all addresses' -- it doesn't need a mask because this is the listen address (rather than an address/subnet to which data will be sent).
