DETAILED DESCRIPTION
This example merely creates some scalar registrations that allows some simple variables to be accessed via SNMP.
In a more realistic example, it is likely that these variables would also be manipulated in other ways outside of SNMP gets/sets.
If this module is compiled into an agent, you should be able to issue snmp commands that look something like (authentication information
not shown in these commands):
snmpget localhost netSnmpExampleInteger.0 netSnmpExampleScalars = 42
snmpset localhost netSnmpExampleInteger.0 = 1234 netSnmpExampleScalars = 1234
snmpget localhost netSnmpExampleInteger.0 netSnmpExampleScalars = 1234

SNMPGET(1) Net-SNMP SNMPGET(1)NAME
snmpget - communicates with a network entity using SNMP GET requests
SYNOPSIS
snmpget [COMMON OPTIONS] [-Cf] OID [OID]...
DESCRIPTION
snmpget is an SNMP application that uses the SNMP GET request to query for information on a network entity. One or more object identifiers
(OIDs) may be given as arguments on the command line. Each variable name is given in the format specified in variables(5).
OPTIONS -Cf If -Cf is not specified, some applications (snmpdelta, snmpget, snmpgetnext and snmpstatus) will try to fix errors returned by the
agent that you were talking to and resend the request. The only time this is really useful is if you specified a OID that didn't
exist in your request and you're using SNMPv1 which requires "all or nothing" kinds of requests.
In addition to this option, snmpget REQUIRES options and agent arguments, as described in the snmpcmd(1) manual page.
EXAMPLES
The command:
snmpget -c public zeus system.sysDescr.0
will retrieve the variable system.sysDescr.0 from the host zeus using the community string public :
system.sysDescr.0 = "SunOS zeus.net.cmu.edu 4.1.3_U1 1 sun4m"
If the network entity has an error processing the request packet, an error packet will be returned and a message will be shown, helping to
pinpoint in what way the request was malformed. If there were other variables in the request, the request will be resent without the bad
variable.
Here is another example. The -c and -v options are defined in the snmpcmd(1) manual page. (Note that system.sysUpTime is an incomplete OID,
as it needs the .0 index appended to it):
snmpget -v1 -Cf -c public localhost system.sysUpTime system.sysContact.0
This example will return the following:
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
This name doesn't exist: system.sysUpTime
Similarly, the command:
snmpget -v1 -c public localhost system.sysUpTime system.sysContact.0
Will return:
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
This name doesn't exist: system.sysUpTime
system.sysContact.0 = STRING: root@localhost
With the -Cf flag specified the application will not try to fix the PDU for you.
