Download

SNMP simulator software is freely available for download from PyPI and project site.

Installation

Just run:

$ pip install snmpsim

How to use SNMP simulator

Once installed, invoke snmpsim-command-responder and point it to a directory with simulation data:

$ snmpsim-command-responder --data-dir=./data --agent-udpv4-endpoint=127.0.0.1:1024

Simulation data is stored in simple plaint-text files having OID|TYPE|VALUE format:

$ cat ./data/public.snmprec
1.3.6.1.2.1.1.1.0|4|Linux 2.6.25.5-smp SMP Tue Jun 19 14:58:11 CDT 2007 i686
1.3.6.1.2.1.1.2.0|6|1.3.6.1.4.1.8072.3.2.10
1.3.6.1.2.1.1.3.0|67|233425120
1.3.6.1.2.1.2.2.1.6.2|4x|00127962f940
1.3.6.1.2.1.4.22.1.3.2.192.21.54.7|64x|c3dafe61
...

Simulator maps query parameters like SNMP community names, SNMPv3 contexts or IP addresses into data files.

You can immediately generate simulation data file by querying existing SNMP agent:

$ snmpsim-record-commands --agent-udpv4-endpoint=demo.snmplabs.com \
    --output-file=./data/public.snmprec
SNMP version 2c, Community name: public
Querying UDP/IPv4 agent at 195.218.195.228:161
Agent response timeout: 3.00 secs, retries: 3
Sending initial GETNEXT request for 1.3.6 (stop at <end-of-mib>)....
OIDs dumped: 182, elapsed: 11.97 sec, rate: 7.00 OIDs/sec, errors: 0

Alternatively, you could build simulation data from a MIB file:

$ snmpsim-record-mibs --output-file=./data/public.snmprec \
    --mib-module=IF-MIB
# MIB module: IF-MIB, from the beginning till the end
# Starting table IF-MIB::ifTable (1.3.6.1.2.1.2.2)
# Synthesizing row #1 of table 1.3.6.1.2.1.2.2.1
...
# Finished table 1.3.6.1.2.1.2.2.1 (10 rows)
# End of IF-MIB, 177 OID(s) dumped

Or even sniff on the wire, recover SNMP traffic there and build simulation data from it.

Besides static files, SNMP simulator can be configured to call its plugin modules for simulation data. We ship plugins to interface SQL and noSQL databases, file-based key-value stores and other sources of information.

We maintain publicly available SNMP simulator instance at demo.snmplabs.com. You are welcome to query it as much as you wish.

Besides stand-alone deployment described above, third-party SNMP Simulator control plane project offers REST API managed mass deployment of multiple snmpsim-command-responder instances.

Documentation

Detailed information on SNMP simulator usage could be found at snmpsim site.

snmpsim's Issues

couldn't create a lot for simulator.

hi.

i can created 1013 simulator.
but i will should create 2026 simulator.
And it was experiencing the following error.

[root@seob ~]# cat ips.txt | wc -l
2026

[root@seob ~]# snmpsimd.py --args-from-file=/root/ips.txt --data-dir=/usr/lib/python2.7/site-packages/snmpsim-0.3.0-py2.7.egg/snmpsim/data --v2c-arch --process-user=root --process-group=root --daemonize --pid-file=/root/snmpsimd.pid
ERROR: socket() failed: [Errno 24] Too many open files

can simulator create a lot ?

Abilty for record strings as Plain text.

I have old and new versions of snmprec:

Old version record string values as plain text.

For devel purposes I prefer to use Plain strings (4) instead hex (4x).

Please add ability (command line argument) for force decode hex strings to plain in snmprec command.

AuthProtocol & PrivProtocol for incoming requests are overridden by Notification variation module

Summary
If authentication and/or privacy protocols differ between snmpsim and that configured in .snmprec for the Notification variation module, then second and subsequent SNMPv3 requests to snmpsim fail with usmStatsWrongDigests.

If for example snmpsim is configured with SHA and AES for authentication and privacy, but the Notification variation module is in use and the authentication and privacy protocols are not specified in the .snmprec file then the second and subsequent SNMPv3 requests incoming to snmpsim fail with usmStatsWrongDigests. This happens because the Notification module defaults to MD5 and DES, and these override the protocols configured in snmpsim.

Expected behaviour
The authentication and privacy protocols used by the notification module should be independent of those used for incoming SNMPv3 traffic to snmpsim.

model different devices

It would be great to host models devices. For example, I wrote a nagios check for dell openmanage devices. After changing companies, to one that did not use Dell, I was unable to continue development.

snmpsimd crashing after 10 min

Hi @etingof ,

I have been using snmpsim for simulating my hardware .On the setup I need to run multiple instances of snmp agent , and I am using the following command to run the agents:
/venv/bin/snmpsimd.py --v2c-arch --data-dir=/data --args-from-file=/data/public/ip_list.txt
--transport-id-offset=1 --process-user=root --process-group=root --daemonize --logging-method=file:/var/log/snmpsimd.log

The simulator is working fine with less nodes in the list(ip_list.txt ), but when the number of nodes is raised to 30 , the daemon is crashing with the following logs:

The daemon is running fine for 5 -10 minutes , and we are getting proper response for the oid , but after some time . the "Request var-binds" response is not correct and the oid received has an omitted "1." , i.e, we are getting "3.6.1.4.1.5419.6.4.1.2.1.10.30" instead of "1.3.6.1.4.1.5419.6.4.1.2.1.10.30" .I have taken multiple runs and every time ,I am getting the same log , with different oid values , and "1." is missing from the reply .

Can you please help me out over here.

Thanks in Advance

can't using my mib file

Hello everybody:
I'm trying to simulate snmp agent so I've used snmpsim but I can't use my own mib file
here is my mib file
could any one help me on that
thanks for supporting
my mib.txt

cache-dir created with wrong ownership when using process-user flag on 0.4.6

snmpsimd.py --process-user=nobody --process-group=nogroup --cache-dir=/tmp/snmp-cache

When running the above command with version 0.4.6, the newly created snmp-cache directory is owned by the user executing snmpsimd.py. On version 0.4.5 and below, the same command creates the cache directory with ownership assigned to the configurable process-user flag, ie. nobody.

This seems like a regression after the file permission changes in the new version.

snmpbulkget doesn't seem to be supported

$ snmpbulkget -v2c -c unit_tests 127.0.0.1:11161 sysDescr.0 sysName.0
Timeout: No Response from 127.0.0.1:11161
$ snmpget -v2c -c unit_tests 127.0.0.1:11161 sysDescr.0 sysName.0
SNMPv2-MIB::sysDescr.0 = STRING: Unit Tests sysDescr
SNMPv2-MIB::sysName.0 = STRING: Unit Tests sysName

Did I miss something?

Response without variable?

Hello.

Is possible to make respond without any value/OID? E.g. when error is used.
That's what happen to me on one device in real use and I would like to reproduce it.

Thank you

snmpsim 0.4.4 error variation module crashes sim UnboundLocalError local variable 'varBinds' referenced before assignment

I'm trying to use snmpsim version 0.4.4 to simulate SNMP Error Responses using the Error Variation Module. I'm developing an SNMP Manager and need to test "out of range" error handling for RFC1592 https://tools.ietf.org/html/rfc1592, Section 3.3.6, Table 18 " SNMP ERROR values for a RESPONSE error code". We're monitoring a SNMP agent device that sometimes returns an "out of range" value of 99 instead of 0 through 18.

I'm currently trying to use the error module but I'm encountering what looks like a defect in snmmpsim when using the error module. snmpsim is crashing with this error

File "C:\Python36-32\Scripts\snmpsimd.py", line 1007, in commandResponderCbFun;    pMod.apiPDU.setVarBinds(rspPDU, varBinds);
UnboundLocalError: local variable 'varBinds' referenced before assignment;

Here are the details of what is happening. My .snmprec file contains this single line

1.3.6.1.2.1.2.2.1.6.1|4:error|status=genError

I'm starting the simulator with a command-line like

snmpsimd.py --v2c-arch --data-dir=C:\dev\snmptest\data --agent-udpv4-endpoint=127.0.0.1:1024 --variation-modules-dir=c:\Python36-32\snmpsim\variation

I'm attempting a simple SNMP GET using SNMP Research's brassd utility getone version 18.1.0.20

getone -v2c -port 1024 127.0.0.1 error 1.3.6.1.2.1.2.2.1.6.1

Unable to request the UDP Port

My first time with Python - I installed the 64 bit python and pip and also the snmpsim.
With help of this command "snmpsimd.py --data-dir=./data --agent-udpv4-endpoint=10.60.120.121:1025"
I was able to get the below message
"Listening at UDP/IPv4 endpoint 10.60.120.121:1025, transport ID 1.3.6.1.6.1.1.0"
Means I am able to start a UDP port on my local ip.

However when I try to execute the below command
"snmprec.py --agent-udpv4-endpoint=10.60.120.121:1025 --output-file=C:/Users/Santhoshkumar.Sekar/AppData/Local/Programs/Python/Python36/snmpsim/data/public.snmprec"
I get this error,
"SNMP Engine error: No SNMP response received before timeout"

Also attached the full logs. Please check and let me know.

Santhosh

Bulkget on non-existent oid table causes snmpsim to go into infinite loop

Hi,

All released versions on github have the same issue except version 0.3.0-2 which can be installed on Ubuntu via sudo apt-get install snmpsim.

snmpbulkget -v2c -c iloop ip:port 1.3.6.1.2.1.2.2.1.2 1.3.6.1.2.1.2.2.1.3 1.3.6.1.2.1.2.2.1.4 1.3.6.1.2.1.2.2.1.5 1.3.6.1.2.1.2.2.1.6 1.3.6.1.2.1.2.2.1.7 1.3.6.1.2.1.2.2.1.8 1.3.6.1.2.1.2.2.1.8 1.3.6.1.2.1.2.2.1.9

Any chance of running `snmpsim` under `pypy`?

Hi,

We're trying to squeeze more performance out of snmpsim, and are attempting to get it to run in a pypy virtual environment.

However, pypy doesn't support the (deprecated) bsddb library upon which snmpsim depends. Is there a workaround or solution that you're aware of that can help us?

Cheers,
Simon.

snmpwalk terminates snmpsimd process while Simulating SNMP Agents

I have recorded oids from a device, placed the rec file in one of the folders and set up the snmpsimd as
snmpsimd --agent-udpv4-endpoint=127.0.0.1:1161
and I get:

...
Listening at UDP/IPv4 endpoint 127.0.0.1:1161, transport ID 1.3.6.1.6.1.1.0

when I do an snmpwalk (also tried snmpget with same results), like:
snmpwalk -On -v1 -c recorded/ubnt-system localhost:1161
snmpsimd process is terminated with Traceback list of calls like:

Is there something going on with my python modules or with the simulator?

All agents at `demo.snmplabs.com` appear to be down

No socket is listening on any of the documented ports:

use Simulator on a Windows machine

from document "To use Simulator on a Windows machine, simply download and run supplied executable to install pre-compiled binaries and demo data files. "
I didn't find this executable file.

snmpsim import error while running with root

I'm trying to use snmpsim to simulate response from a switch. I need to open 161 port to get the management end fooled by snmpsim. I ran it as normal user without problems but when I ran it as root it gives-me an error.

Exception when invoking as root using udp port 161

snmpsim loads but then fails when queried. This only happens when invoking as root on port 161. When running on a non privileged port as a user it works great.

I would like the simulator to answer get requisitions on the default SNMP port (port 161).
Is that possible?

snmpsimd.py: Command line options documentation

Looking at the doc, I just can't find the description each command line options for the snmpsimd.py.
It would be nice to have a documentation like the one for the forwarder - http://snmplabs.com/snmpfwd/configuration/index.html

Having it when doing --help would ne handy too ;)

No mib2dev from Free SNMP simulator in ubuntu 16.4

I have installed free SNMP simulator and I followed the installation instructions: https://github.com/etingof/snmpsim and everything seemed to be ok.

However, when I tried to mib2dev tool I get command not found.
When I tried to find if it exists i get:

    ~$ sudo find -name "mib2dev"
    ./.local/snmpsim/data/mib2dev

but still no mib2dev.py anywhere.

    ~/.local/snmpsim/data/mib2dev$ ls -a
    host-resources-mib.snmprec  ip-mib.snmprec  tcp-mib.snmprec  udp-mib.snmprec

I even tried reinstalling but nothing changed.
Any help would be appreciated.

variation-module-options not picking up custom notifications

I'm setting up my own notifications.snmprec locally, and want to start the simulator with it. For that I use the --variation-module-options cli option:

> snmpsimd.py ... --variation-module-options=file:./test/custom/notifications.snmprec

For testing purposes, I'm only using v1, which notifies on sysDescr.0 get request. I've replaced all instances of localhost ip address to all:

# in the original, 0.0.0.0 is 127.0.0.1

1.3.6.1.2.1.1.1.0|4:notification|op=get,version=1,community=public,proto=udp,host=0.0.0.0,port=162,ntftype=trap,trapoid=1.3.6.1.4.1.20408.4.1.1.2.0.432,uptime=12345,agentaddress=0.0.0.0,enterprise=1.3.6.1.4.1.20408.4.1.1.2,varbinds=1.3.6.1.2.1.1.1.0:s:snmpsim agent:1.3.6.1.2.1.1.3.0:i:42,value=SNMPv1 trap sender

However, I'm not seeing the simulator picking up the variation module. Nothing in the boot log shows me that. Neither does the notification log, when I send the aforementioned get request:

generateRequestMsg: Message:

I still see 127.0.0.1, so I conclude that the option was ignored.

Is this a bug or a wrong usage of the platform?

Just as a note on why this is important for me: I'm running the simulator in a docker container for isolation. I want to expose port 162 of the container and listen there for the notifications, so the snmpsim has to be sending the notifications to 0.0.0.0 interface.

Retransmit(doublicate) SNMP packet

hi guys
i have a question about retransmit SNMP message

I want realize next scheme
SNMP-client send SNMP packet to one SNMP-server that's will listening one port (for example 172.16.77.10:161)
On that port listening software that retransmit(doublicate) SNMP packet to two different host (for example 172.16.77.20:161 and 172.16.77.30:161 )

Can i embody this cheme?

Unable to create simulation data for IF-MIB

Hi!

I'm trying to simulate a snmp capable switch so I want to create IF-MIB data for achieving that. But when I try to create the simulation data I got a weird ValueError. I can't figure out what is happening.

Here is the output:

➜  qemu-vms git:(master) ✗ mib2dev.py --mib-module=IF-MIB 
# MIB module: IF-MIB, from the beginning till the end
# Starting table IF-MIB::ifTable (1.3.6.1.2.1.2.2)
*** Inconsistent value: Display format eval failure: b'kept acted forward but oxen': invalid literal for int() with base 16: 'kept acted forward but oxen'caused by <class 'ValueError'>: invalid literal for int() with base 16: 'kept acted forward but oxen'
*** See constraints and suggest a better one for:
# Table IF-MIB::ifTable
# Row IF-MIB::ifEntry
# Index IF-MIB::ifIndex (type InterfaceIndex)
# Column IF-MIB::ifPhysAddress (type PhysAddress)
# Value ['kept acted forward but oxen'] ?

The snipped kept acted forward but oxen change every time I ran, as was something random to fill gaps. I can't understand from where it is coming from :-/. How can I further debug this?

pcap2dev.py does not support encrypted .pcap traffic

In order to simulate a large switch, we have captured a pcap file of an snmpbulkwalk of (almost) an entire switch. However, this was done using SNMPv3 with -l authPriv, so the resulting pcap file contains encrypted SNMP traffic.

It appears that pcap2dev.py has no means to decrypt such a pcap file. Is this possible?

(and no, it was not possible to use snmprec.py to bulk-walk the switch; the host from which we walked the switch does not have snmpsim installed, and we cannot install it there for reasons).

Cannot contact SNMP agent

Hi,

I am trying to simulate a Brother printer.
I use SNMP Agent Simulator on a ubuntu computer.

I recorded the data with snmprec:
snmprec --protocol-version=1 --agent-udpv4-endpoint=192.168.1.100 --start-oid=1.3.6.1.2.1.1.1.0 --stop-oid=1.3.6.1.4.1.2435.2.4.3.1240.1.3.0 --output-file=/usr/share/doc/snmpsim/examples/data/recorded/Brother.snmprec

When I run the agent with the following command:
snmpsimd --agent-udpv4-endpoint=localhost:161 --agent-udpv6-endpoint='[::1]:161' --process-user=simulator --process-group=simulator`

the installation wizard of the printer does not find the agent on the network.
I noticed that, when running the agent, I get:
Listening at UDP/IPv4 endpoint localhost:161, transport ID 1.3.6.1.6.1.1.0 Listening at UDP/IPv6 endpoint [::1]:161, transport ID 1.3.6.1.2.1.100.1.2.0

but the SNMP requests from the installation wizard are:
1.3.6.1.2.1.1.1.0
1.3.6.1.2.1.1.5.0
1.3.6.1.2.1.1.6.0
1.3.6.1.2.1.2.2.1.6.1
1.3.6.1.4.1.1240.2.3.4.5.2.6.0
1.3.6.1.4.1.2435.2.3.9.1.1.7.0
1.3.6.1.4.1.2435.2.4.3.1240.1.3.0

Maybe there is another issue, but it looks like the agent is not listening on the correct transport ID.
How can I change that? I do not find any option for that.

Thank you for your help.

variation module not given snmpEngine

Thanks for writing this Simulator; it is a great software.

Variation module notification.py reports this error when attempting to snmpget the "trigger OID":

2018-03-16 16:14:41,810 snmpsimd: data error at /home/qrobinson/.snmpsim/data/notify.snmprec controller for 1.3.6.1.4.1.5591.1.3.1.1.0: variation module not given snmpEngine

I found a thread dated from Thu, Nov 7 2013 addressing this issue here.
The error persists since updating snmpsim to the latest release (0.4.4) with pip; please advise.

Any .snmprec files repository?

Hi,

I'm wondering if there is any snmp rec repository available with different type of device rec ?

Best regards

There is no CPU data?

I can't find the CPU info in the public community

$ snmpwalk -v 2c -c public 127.0.0.1| grep -i cpu
$

Improve performance

Hi @etingof

Thanks for snmpsim, we are using it at https://github.com/librenms/librenms to test our software.

I was wondering if you had any tips or perhaps code improvements to speed up our tests run time. We've only just started adding data to automated tests and the time is starting to add up. Our unit tests are up to almost 9 minutes.

Migrate from pylibpcap

The pcap2dev.py tool relies upon pylibpcap for traffic dissection.

It seems that pylibpcap project is dead. It is probably time to migrate to a more lively Python wrapper around pcap. May be pcapy or something else.

Variation module 'writecache' referenced but not loaded

I install the SNMPsim on my site. And I convert the file to the format of .snmprec. When I start the sim, I found an error "Variation module 'writecache' referenced but not loaded" when I get a request from the "iftable".
1.3.6.1.2.1.2.2.1.7.1|2:writecache|value=1
This is my command for start SNMPsim.

Variation Modules limitations

Hello @etingof,

First of all, thank you for creating SNMPSim and supporting it. We are currently using your tool to simulate Cisco and Xirrus Access Points. We used the snmprec functionality to create .snmprec files based on real Cisco and Xirrus devices and it worked perfectly.

Since we needed to simulate SNMPSet behaviour, I read SNMPSim's documentation regarding varation modules and since I picked the writecache module. Editing the snmprecs generated from the Access Points, I changed all OIDs I was interested to edit according to the tutorial to be like this:

1.3.2.4.23.3|2:writecache|value=27 for example.

However, I noticed that the writecache flag seems to be incompatible with encoded datatypes. For example, some Xirrus OIDs contain encoded strings and have the '4x' datatype instead of simply '4.
When SNMPSim tries to parse '4x:writecache' it throws an error about invalid type. Consequently, I added 'writecache' only to non-encoded OIDs.

Is there any way to use the writecache for encoded OIDs or should I resort to other solutions such as MySQL backed storage.

Finally, I attempted to create a new Tunnel on my simulated Xirrus device. To do this, I have to add new OIDs while the simulation is running that reflect the tunnel creation on the device. I can easily do this by editing the .snmprec file and SNMPSim will detect it. However, this is not a desirable solution in our case and I would like to know if there are other ways in which I can instruct SNMPSim to create new OIDs and then fetch them via SNMPGet. Will a MySQL backend once again help here?

Your help would be much appreciated, thanks in advance!

Please update manual at sourceforge

Regarding variation modules usage examples:
gauge and counter which were merged into numeric.

Thank you for your project

mib2dev prints enum text instead of numerical values

Hi,

I'm trying to use mib2dev to generate some simulation data, however when I run it is printing the enum text values instead of the numerical ones.
The problem with this is that when I try to use this file on the simulator it complains because the data doesn't match the type (is expecting numbers and not text I presume).

There is any way to tell the script to print the integer values instead of the text?

Thanks.

Running 'pip install snmpsim' with python2.6 installs snmpsim for python3.5

Hi!

I'm having problems installing snmpsim with python2.6.6, when I was using pip 1.3 is worked perfectly since it fetched the egg files but now when I'm using a newer version of pip it tries to use the wheel file. I had a look at pypi https://pypi.python.org/pypi/snmpsim/0.3.0 and found that the Py Version states 3.5 when I think it should be py2.py3.

I think this is the same problem described here: http://stackoverflow.com/questions/30438216/how-do-i-upload-a-universal-python-wheel-for-python-2-and-3

Have a nice day!

should it be ?

    if rowOID and rowOID.isPrefixOf(oid):

Pip install on windows is not enough

Hello.

On windows the simulator can't be simply installed with pip install snmpsim.
I had to download the repository and run python setup.py install from the folder to get the simulator to work, which I found accidentally in issue #14 . This setup file is not included in the pip installation. The download version must be same (last release is now 0.4.6, on pip is 0.4.5)

It took me a while to figure it out. Would be nice to have it in wiki or working pip installation.

After successful install I found, that SNMP-error 1 (TooBig) is not possible to simulate, but never mind :D

Installation problem in windows7

Iam using latest version of vxsnmpsimulator-2.0.1 . I am following steps that you mentioned in readme file.
But it is throwing me error like as follows
Error: Could not find or load main class Files\Java\jdk1.8.0_60\bin\JAVA -jar j
ar\SnmpAgentSimulator-jetty-console.war --headless --contextPath .SnmpAgentSimul
ator --port 8080
I checked java path also(i reinstalled also).
Iam thinking that is due to any port issues. please help me in this.
Thanks in advance.
