When I run the following

[root@host plugins]# ./check_hpjd -H printer1.mydomain.com : Timeout from host printer1.mydomain.com

I have Net-snmp installed on my system, I noted that i didn't have net-snmp-utils installed, and then I was able to run

[root@host plugins]# snmpwalk -Os -c public -v 1 printer1.mydomain.com system

sysDescr.0 = STRING: HP ETHERNET MULTI-ENVIRONMENT sysObjectID.0 = OID: enterprises.11.2.3.9.1 sysUpTimeInstance = Timeticks: (325408663) 37 days, 15:54:46.63 sysContact.0 = STRING: sysName.0 = STRING: printer1 sysLocation.0 = STRING: sysServices.0 = INTEGER: 72

So I know that the printer is working as expected, (as far as SNMP is concerned). But when I run

[root@host plugins]# ./check_hpjd -H printer1.mydomain.com -C public Error in packet ()

I get this error - From what I've tried so far, I know my host can communicate via SNMP, I know the printer responds via SNMP, so I guess I'm left to look at the plug-in, which I will be checking up on. I'm new to SNMP, I am investigating this with my good friend Google search, but I am on a learning curve here, so please forgive my questions if they sound stupid,
