Re: [nv-l] Net-snmp on suse 9

[George deSocio <desocio@us.ibm.com>]

Hello list, one more time,

After one more test, I found there are
two ways to build the flags for net-snmp's snmpd daemon that will correctly
handle the pass statement in the conf file, and stay running.

1)  -C -c /etc/snmpd.conf  
<or>   -Cc /etc/snmpd/conf

2)  <neither of the above, that
is no -C, and no "-c /etc/snmpd.conf">

The conclusion I have come to is this:

With only "-c /etc/snmpd.conf"
coded (in /etc/init.d/snmpd after the rpm is installed), the default conf
file, /etc/snmpd.conf, is being processed twice.  Once because -C
is not specified, and once because -c is specified.  With a pass statement
coded, processing the pass statement twice is what appears to cause the
core.  At least that's the mile high view based on what I can see
in an strace output.

With neither "-C" or "-c
/etc/snmpd.conf" specified, the default is processed (which is /etc/snmpd.conf),
snmpd activates correctly and works correctly.

Regards,
Geo.

Hello list, 

As a followup to the original question to the list:  

We found that the release of net-snmp found in some newer SUSE 9's,  net-snmp-5.1-80.11,
when the pass statement (any pass statement) is added to /etc/snmpd.conf,
snmpd cores with signal 11 (SIGSEGV).  This doesn't seem to be known
in the net-snmp community. 

In /etc/init.d/snmpd script, there is a command, startproc.  Add a
-C flag after $SNMPD.   After that change, the daemon comes up, processes
the pass statement, and stays up.  mgragentd also works and gets passed
its oid part. 

I don't know why this works :-)     But it does work around the
problem as far as NetView is concerned. 

This looks like a bug in net-snmp.

Geo.

Subject	[nv-l] Net-snmp on suse 9

Does anyone have net-snmp working on suse 9, instead of ucd-snmp?  This
is for netview 7.1.4 fixpack 3.  If I put in the lines:

pass .1.3.6.1.4.1.2.6.4.6.1 /bin/sh /usr/OV/bin/mgragentd
view system included .1

Snmp won't start up.  It starts up fine without these.

TIA
