Question about setting up IEXpress net-snmp for HP UX 11.23.

[Paul Hogan]

Our company uses the Orion snmp monitoring tool to monitor systems in
our environment. We have had no problems monitoring systems with this
tool, however our HP UX systems only come with very basic SNMP
monitoring enabled (Essentially, up down and that is it). We would like
to monitor Disk, CPU, Network interface... More than what the HP UX
SNMP system does by default. Through some threads on the internet I was
able to find the IEXpress net-snmp bundle that is out of HP's web site
and download it. I have installed this software on a HPUX 9000/800
system running 11.23. It appears this bundle was specifically made for
this system. Since I am new to the SNMP added software I don't know the
steps to get this running and monitoring the system correctly. Can
someone give me a step by step on how to set this up on this type of
system? If there is something on the web site that gives this step by
step that is fine. I am just not seeing a straight forward way to do
this, and I don't want to reinvent the wheel if I don't have to. I
would also like to make sure the original SNMP daemon that comes with
the HP OS is disabled and I am using the net-snmp software for SNMP
monitoring. Thanks in advance for any information.

If you have problems using a vendor's Net-SNMP package, then it'd
probably make sense to ask that vendor first.

For general questions on how to use/configure Net-SNMP, you may want to
consult the Net-SNMP FAQ:

http://www.net-snmp.org/wiki/index.php/FAQ

and/or browse the other documents on http://www.net-snmp.org/ .

Paul,



I am traveling down precisely the same path as you. Also on an HP-UX
11.23 system. I understand that you have installed Net-SNMP via a
bundle from IEXpress, good. Ok, I can help you a little bit as I have
just got the autostarting of the net-snmp snmpd working on my system
this evening.



Basically, you will be tweaking the /sbin/init.d/SnmpMaster script to
have it point to the new code for Net-SNMP that installed in
/opt/iexpress/net-snmp/sbin/snmpd . However, there are some
preliminaries. I first recommend that you do a ps -ea | grep -i nmp and
see if snmpd is still running. If so, kill it via kill -9 [pid] .



Now, you can go ahead and create a valid config for your net-snmp
install and test. First, recreate a valid snmpd.conf file and put it
in /opt/iexpress/net-snmp/etc/snmp directory (you may need to create a
directory, I had to). Just one line is all that is necessary in that
snmpd.conf to get things started: rocommunity public That is
enough in the file to be a valid config. Granted, you may not want to
run using the get-community-name of public, bad security there, but this
is just to get things rolling. There is a configuration script at
/opt/iexpress/net-snmp/bin/snmpconf that will do a guided creation of a
this same file if you prefer.



Ok, so now we have a valid snmpd.conf file and have put it where it
goes. Now, if you want to make 100% sure you are starting net-snmp
with the config file you created call it all explicitly like this:

/opt/iexpress/net-snmp/sbin/snmpd -c
/opt/iexpress/net-snmp/etc/snmp/snmpd.conf Now that you have
started it, lets test it with a call to snmpwalk and see if we get some
valid output, like this:

snmpwalk -v 1 -c public localhost .1.3.6.1.2.1.25.3.2 That should
fill your terminal screen with plenty of valid output, otherwise it will
act stupid and not do anything and you will know that you do not have
snmpd started yet.



Ok, with config and test done, now is the time to do two things. First,
you will want to turn off all the Snmp related scripts on the system.
Do this by going to /etc/rc.conf.d and doing a ll *nmp* to locate all
the old Snmp related script config files. Edit each one changing 1 to 0
disable the start up. I am assuming you are following the Unix stuff
here. If not, write to me on the side and I will be glad to explain.
Also, in the SnmpMaster file you will want to leave it set at 1, because
that is the script we will modify to do our startup for net-snmp version
of snmpd. Next, for the second big thing, edit the
/sbin/init.d/SnmpMaster script to call the net-snmp code. I won't
explain it step by step, but I will just copy the critical text I
changed. You can compare to your original file and see what I did.
Here are the critical changes, look for the differences very carefully
(particularly that you will be changing snmpdm to snmpd):



PATH=/sbin:/usr/sbin:/usr/bin:/opt/iexpress/net-snmp/sbin:/opt/iexpress/
net-snmp/etc/snmp

export PATH





StartMasterAgent()

{

setPort

eval /opt/iexpress/net-snmp/sbin/snmpd -c
/opt/iexpress/net-snmp/etc/snmp/snmpd.conf ${SNMP_MASTER_OPTIONS:-}

set_return





StopMasterAgent()

{

#

# Determine PID of process(es) to stop

#

pid=`ps -e | awk '$NF~/snmpd/ {print $1}'`





if [ "X$pid" != "X" ]; then

if kill -9 $pid; then

echo "snmpd stopped"

else

set_return

echo "Unable to stop snmpd"

fi

fi

}





Ok, this is it! You should be able to use /sbin/init.d/SnmpMaster stop
and sbin/init.d/SnmpMaster start to stop and start the net-snmp snmpd
daemon now. Verify this works by checking you processes and validate.
Now, if you can, give that system a reboot and again validate that the
snmpd daemon is running. Check the processes and test with snmpwalk
again. You should be good to go!



Oh yes, how to fix up Orion to use it? I am still discovering that
myself, so I don't have anything really useful to offer other than if
you have that host already in Orion you should now have options for more
things concerning that host than you had before with the HP version of
snmpd. Getting my SolarWinds product all set up is my next task. I
hope this has been of some help. Good luck! :-)



P.S. If some of the other folks on this email group have better
suggestions or see where I have made mistakes, please let them chime in.
This was my first effort and likely has flaws. BUT IT DOES WORK!
