Re: snmpset gives an gen Error message

Hi Jack;
 
The error was in the handler I implemented.  I comitted a silly mistake of deleting the modes I did not have code for, for example:
 
int syslocation_handler(netsnmp_mib_handler *handler,
                                  netsnmp_handler_registration *reginfo,
                                  netsnmp_agent_request_info *reqinfo,
                                  netsnmp_request_info *requests) {
 
     switch (reqinfo->mode) {
          case MODE_GET:
              // my code here
              break;
          case MODE_SET_ACTION:
             // my code here
              break;
          default:
              return SNMP_ERR_GENERR;
     }
     return SNMP_ERR_NOERROR;
}
 
as you see, I'm missing MODE_SET_RESERVE1, MODE_SET_RESERVE2, MODE_SET_UNDO, MODE_SET_COMMIT, and MODE_SET_FREE, so in such instances, the routine returns SNMP_ERR_GENERR.
 
if you do a snmpget, it will not create this error, as it does not go through the several SET modes as in snmpset.
 
Hope it helps,

Hi,
 
I've been extending the snmpd with my own modules.  I made sure that each module is working properly before adding another one.
 
Suddendly, on one of the latest modules, netsnmp builds ok, but I get an error while using snmpset command.
 
I also tested the snmpset with a library in c# separate from netsnmp, and it does not work either.
 
I removed the module, and re-build the netsnmp and still gives me the error.
 
The error is:
 
$snmpset -v1 -cprivate localhost myvar.0 i 0
Error in packet.
Reason: (genError) A general failure occured
 
it happens with each oid I've implemented.  I'm using net-snmp-5.6.rc1.
 
I also though that maybe the modules that I've extended created some seg-fault, and overwrite some source/header files in net-snmp, so I re-install (tar) the whole netsnmp, but I still get the error.
 
I'm not too sure what could cause this sudden error.  I reverted to only the modules that was working fine before, and I did not change the MIB or the snmpd.conf files.
 
Thanks!
