[HOWTO] Install and configure the Net-SNMP agent for Windows

[abhijitdas]

hi, fmangeant

I have gone through the all the question and answer of the "Install and configure the Net-SNMP agent for Windows". Now I have done all the steps correctly according to your answers. I am giving the points as
1. I installed net-snmp-5.4.2.1-1.win32.exe and followed your steps.
2. I am getting all the relevent o/p of the command as you mentioned.
3. In the log file ,C:\usr\log\snmpd.log , I am getting only
NET-SNMP version 5.4.2.1,
Is it correct?
4. I did not do anything about snmptrap.

Now, I have seen that sometime stop and start od snmp are not working correctly.

My requirement is , to get the CPU load. I did
1. install the net-snmp
2. get the jar of snmp " snmp-1.3.jar" ,
3. JRobinLite-1.5.9.1.tar.gz - for getting the CPU load.

Now, I do i know that my net-snmp is working correctly. Is the log info. is correct.

The java file of JRobin shows exception ....
The error is in
public static final String SNMP_CPU_LOAD_OID = "1.3.6.1.4.1.2021.10.1.3.1";

not able to retrive.

Thanks

For those getting unknown token warnings when running SNMP queries, make sure you have set an environment variable called SNMPCONF-PATH to the path of your Net-SNMP snmp.conf file

Yep, i have that "unknown token" problem monitoring a windows client, but i don't understand your message.

This is the data on my C:\usr\etc\snmp\snmp.conf

mibdirs C:/usr/share/snmp/mibs
persistentDir C:/usr/snmp/persist
tempFilePattern C:/usr/temp/snmpdXXXXXX
rocommunity public

And this is what happen when i do the snmpwalk:

C:\Documents and Settings\Admin>snmpwalk.exe -v 1 -c public localhost sysdesc
C:/usr/etc/snmp/snmp.conf: line 4: Warning: Unknown token: rocommunity.
Timeout: No Response from localhost

¿Any idea?

Never mind, I was editing snmp.conf not snmpd.conf X_X

C:\net-snmp\bin>snmpwalk.exe -v 1 -c public localhost versiontag
Output: UCD-SNMP-MIB::versionTag.0 = STRING: 5.4.1

C:\net-snmp\bin>snmpwalk.exe -v 1 -c public localhost sysdesc
Output: No output.....Its blank..

I had this same issue, and resolved it by installing Cacti as a service manually through the command line. Instead of running "Register Agent Service" from the Start Menu, I ran the following in the command line after installing Net-SNMP: "snmpd -register -Lf c:/snmpderr.log". Change c:/snmpderr.log to where you'd like it to log errors.


EDIT: This appears to just re-enable Net-SNMP's built in modules. I'm now toying with explicitly proxying requests.

EDIT 2: I used the above directions to install as a service, and then did the following:

Installing Net-SNMP as a proxy:

1. Install Microsoft SNMP Agent as normal
2. Run "notepad c:\windows\system32\drivers\etc\services", find snmp, replace 161 with 1161
3. Start or restart Microsoft SNMP Agent
4. Edit your snmpd.conf--add community strings and a line saying "proxy -v 1 -c <COMMUNITY_STRING> localhost:1161 .1.3"
5. Start or restart Net-SNMP service

If you get timeouts while trying to do a walk, make sure both SNMP services are running. Works perfectly for me so far.

Hi,

Firstly, thank you for the tutorial.


Then i have a little problem, and i hope than you will able to help me.

So i have installed Net-SNMP on windows with your tutorial. All feature work except the "proc" directive. I have used this directive on Linux and it's very useful to look for specific process that's why i ask if they are an issue use this directive on windows ?

I have searched on google for long (long long... ) time without issue...However, i have read that it's was probably not implemented on windows. Someone have an idea of issue to have the same features (trap on stop or too many process, get the state of one type of process...) without HOST-RESSOURCE-MIB.

Thank you

(Sorry for my bad english, i hope than my explication is understandable).

I´m having some problem with SNMP v3, I followed the HOW TO and the 2 link above.
I created a user at snmpd.conf too and still getting this error.

Encryption support not enabled.
snmpwalk: USM encryption error

my net-snmp was installed with Cacti instalation for windows:
If I check Log i get only:
NET-SNMP version 5.6.1.1

Any tips to help how to make SNMP v3 on windows 2k3?
I need to make this work to try to make a template to Mcafee IPS.

Thanks.

Hi, im having problems with these.

I ran the net-snmp installer and followed all the steps, then i've tried to verify that Net-SNMP was installed correctly running the following from a command prompt:

snmptranslate -IR -Td IF-MIB::linkDown

And what i can see is these

Does someone know what can i do? help!

When SNMP daemon starts, any error message is logged in C:\usr\log.

In my case, I resolved timeout problem by
1) Creating snmpd.conf file using snmpconf -g basic_setup
2) moving the snmpd.conf file from C:\usr\share\snmp to c:\usr\etc\snmp

snmpd.conf doesn't exist for me... or maybe i need to downgrade? i use 5.7.0 NET-SNMP

Code: Select all

snmpconf -i

The following installed configuration files were found:

   1:  c:/usr/etc/snmp/snmp.conf

Would you like me to read them in?  Their content will be merged with the
output files created by this session.

Hi,

I've followed the steps and I've got net-snmp installed on my Windows server 2008 R2 machine.

In Cacti - I don't seem to be able to have the option to choose a graph to show available disk space.

I've added the device net-snmp device however when I chose graphs I don't have Net-SNMP - Available Disk Space even though I see it as a template....

any ideas anyone?

[netniV]

If you device is based on a device template, add the graph template to the device template, then resync the device template to devices.

[hillda01]

Apologies for being not quite so switched on with this but how do I go about copying the template...

I've looked in the interface and it's not immediately obvious.

[netniV]

You shouldn't need to copy the template if you are just adding a new graph template to the device template. You just add it on the device template.
