Hi,
this is a long e-mail again because i attached some code

i have found the missing mib (JETDIRECT3-MIB) that is needed to resolve the
OIDs above but i have some trouble implementing these Objects.
These are scalar objects and i used the mib2c.scalar.conf to generate the
template code
i implemented the class as i always do it for scalars. (i will attach the
code for the OID 1.3.6.1.4.1.11.2.4.3.13.1 as an example)
I get the error that the Object i implement is not in the agent
snmpget -v1 -cpublic 192.168.2.101 npIpxGetUnitCfgResp2.1
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: JETDIRECT3-MIB::npIpxGetUnitCfgResp2.7
snmpget -v2c -cpublic 192.168.2.101 npIpxGetUnitCfgResp2.1
JETDIRECT3-MIB::npIpxGetUnitCfgResp2.1 = No Such Object available on this
agent at this OID
the npIpxGetUnitCfg2 as example Object for understanding
npIpxGetUnitCfgResp2 OBJECT-TYPE
SYNTAX OCTET STRING
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"This object is the Get Unit Config Response
structure described in the IPX code. This
structure is of variable length depending
on how many servers are configured. This is
the second set of info when more than
8 print servers are configured."
::={ npIpx 7 }
And here are the entries in the header files that are relevant to compile
this object into the agent:
mib_module_inits.h
#ifdef USING_HP_NPIPXGETUNITCFGRESP2_MODULE
if (should_init("npIpxGetUnitCfgResp2")) init_npIpxGetUnitCfgResp2();
#endif
mib_module_includes.h
#ifdef USING_HP_NPIPXGETUNITCFGRESP2_MODULE
#include "mibgroup/hp/npIpxGetUnitCfgResp2.h"
#endif
and mib_module_config.h
#ifdef USING_HP_MODULE
#define USING_HP_NPIPXGETUNITCFGRESP2_MODULE 1
#endif
and the MIB Jetdirect3-MIB is defined in net-snmp-config.h
#define DEFAULT_MIBS
"IP-MIB;IF-MIB;TCP-MIB;UDP-MIB;HOST-RESOURCES-MIB;SNMPv2-MIB;RFC1213-MIB;NOTIFICATION-LOG-MIB;UCD-SNMP-MIB;SNMP-TARGET-MIB;NET-SNMP-AGENT-MIB;DISMAN-EVENT-MIB;SNMP-VIEW-BASED-ACM-MIB;SNMP-COMMUNITY-MIB;UCD-DLMOD-MIB;SNMP-FRAMEWORK-MIB;SNMP-MPD-MIB;SNMP-USER-BASED-SM-MIB;SNMP-NOTIFICATION-MIB;SNMPv2-TM;LaserJet-Series4050-MIB;Printer-MIB;JETDIRECT3-MIB"
and here is the implementation i usually use for string type scalars

Is the code wrong or could it be a bad MIB?
I have downloaded the JETDIRECT3-MIB (the new version because the older one
is buggy) from www.mibdepot.com
Sorry for messing you with this details but I don't see where i make
something wrong. Perhaps you can give some suggestions. Thanks in advance
for your understanding
With best regards
