Query regarding "pass" example in snmpd.conf
Kevin Shaw
All,
First of all, apologies for the question below, but I'm new to SNMP and
NET-SNMP.
EXAMPLE.conf contains the following example of the use of "pass":
pass .1.3.6.1.4.1.2021.255 /bin/sh $PREFIX/local/passtest
I have added this to my $HOME/.snmp/snmpd.conf file, and started my local snmpd
listening on a free port.
If I do an snmpwalk of "enterprises.ucdavis" (.1.3.6.1.4.1.2021) I get the
following lines of interest:
enterprises.ucdavis.mrTable.mrEntry.mrIndex.1.3.6.1.4.1.2021.255 = OID:
enterprises.ucdavis.255
enterprises.ucdavis.mrTable.mrEntry.mrModuleName.1.3.6.1.4.1.2021.255 = pass
Which seems OK. However, if I run the example use of snmpwalk (again from
EXAMPLE.conf):
snmpwalk -v 1 localhost public .1.3.6.1.4.1.2021.255
I get no output. And if I try:
snmpget -v 1 localhost public .1.3.6.1.4.1.2021.255.5
I get the error indicating that the variable is not in the MIB.
If I run
/bin/sh $PREFIX/local/passtest -n .1.3.6.1.4.1.2021.255
I get the expected output:
..1.3.6.1.4.1.2021.255.1
string
life the universe and everything
Both of these failures lead me to think that I have not done what I need to do
to properly register the .1.3.6.1.4.1.2021.255 MIB, but I have no idea how I
should go about doing this. Can anyone help ?
I like to know what I need to do to make the example (the use of the passtest
script) work.
Thanks in advance for any help

I haven't really used this much myself - but one thought springs to mind.
Do you actually have the token "$PREFIX" in this file, or have you
replaced this with the appropriate path to the passtest script?
Because that would be one obvious possible cause of the script failing.
Is anything being logged by the snmpd agent?

The file contains the full path, not the $PREFIX token. But I will have a look
at the logging produced by the snmpd.
Thanks

All,
Further to my email below, if I run the following snmpget:
snmpget telsun4 public .1.3.6.1.4.1.2021.255.5
I get the following in the log file with debug on:
snmp_vars: Looking for: enterprises.ucdavis.255.5 ...
trace: getStatPtr(): snmp_vars.c, 445
snmp_vars: Trying tree: enterprises.ucdavis.255 ...
trace: search_subtree_vars(): snmp_vars.c, 328
snmp_vars: Trying variable: enterprises.ucdavis.255 ...
trace: var_extensible_pass(): ucd-snmp/pass.c, 246
ucd-snmp/pass: pass-running: /bin/sh
/export/home/kshaw/ucd-snmp/ucd-snmp-4.2/local/passtest -g
..1.3.6.1.4.1.2021.255.5
open: No such file or directory
However, if I run the script with the parameters indicated, I get the following
output:
telsun4 /export/home/kshaw/ucd-snmp/ucd-snmp-4.2/bin> /bin/sh
/export/home/kshaw/ucd-snmp/ucd-snmp-4.2/local/passtest -g
..1.3.6.1.4.1.2021.255.5
..1.3.6.1.4.1.2021.255.5
counter
42
The 3 lines of output are those expected.
My feeling is that I am missing some simple piece of configuration, it's just
that I don't know what that piece of configuration is:
Any help would be gratefully received.

All,
I new it woud be a stupid one. Having looked at the code, the problem is caused
by the agent not having write access to create the persistent data storage
directory. Once this is remedied, everything works OK.
