I am working on an fax grabber, for a fax in our building only Samsung provides the software "Samsung Easy Printer Manager" the program sends an SNMPGET to the Printer as I saw in Wireshark

But if im sending the get Request from my Laptop I get:

SNMPv2-SMI::enterprises.236.11.5.11.81.12.16.1.2.1 = No Such Instance currently exists at this OID

and after i googled the OID there was no result. Any Ideas

  • From Wireshark, what did you send exactly? Compare it to the one sent by "Samsung Easy Printer Manager" and focus on the differences. – Lex Li Jul 23 '22 at 20:46
  • can you include the exact command you used on your laptop? – TallChuck Jul 29 '22 at 17:56
  • i figured it out, i think the printer is changing the OID from 0-5 as a new device connects via http request. – BlackAura Aug 01 '22 at 19:03
