i need to write a simple programm, to show a message every time a list of possible oID SNMP is received.
My list oID is:
oids = ['1.3.6.1.4.1.31448.1.1.0.9', '1.3.6.1.4.1.31448.1.1.0.13','1.3.6.1.4.1.31448.1.1.0.14','1.3.6.1.4.1.31448.1.1.0.15','1.3.6.1.4.1.31448.1.1.0.19','1.3.6.1.4.1.31448.1.1.0.23']
The reason is when PC receives one of these traps, there is a problem in device, and software must only show a warning. Nothing more.
thanks for your answer. I understand what you say and it´s so.
i explain what i have done.
SNMP version can be V1 orV2.
At the moment, i can´t paste python code, but i have tested with TrapAgentAddress='0.0.0.0' // TrapAgentAddress='127.0.0.1' but i don´t receive any message about receiving trap.
When i execute, it only show:
Agent is listening SNMP Trap on 0.0.0.0 , Port : 162
I know that i´m receiving traps, because i have received with WIRESHARK at same time.
I would like to insert an image, but i don´t know to do it. I have tried to paste python code, but i´m not be able to do it.
I´m very thanked for your support.
BR,
Antonio

I have a something that is sending an SNMP set command to my server. I can see the packet in wireshark, and I know that I'm getting the packet. Once I get this packet I need to decode it and do an operation (using a script). I can't believe I am the first person that needs to do this, but have googled for hours and found no one else in this use case. I've seen utilities that allow me to use a get snmp, but as the set doesn't actually set anything on my server, there is no way to get it. It doesn't seem traps are helpful as that seems to find the message, as its not labeled a trap. Is there a way to convert the set to a trap once my server gets it, or is there a better method. My server is windows, but if I have to create a linux VM to make this easier I'm all ears. As of now I'm thinking powershell, but if there is an easy way in go, c#, etc I would totally do it.
I am attempting to get a SNMP SET to and use that as a trigger for running a script.
You are 100% correct in that you are not the first person to ask this question. The answer depends on which SNMP agent you have deployed. Many people have had success with Net SNMP and if you want to invoke a shell script from the SNMP agent, see this tutorial. Good luck with your project.
I ended up using pythons pysnmp to build an agent that would recieve the set/get requests. I had to compile my own MIBs for the PDU I was emulating, but got the job done. I also looked into Net SNMP, but I'm more familiar with python and found many helpful examples and good documentation.
I would like to flatten my use case, but at the moment I have two scripts, one that is the agent using pysnmp and one that will do a get request to see what the value is and set off a ssh script. I wish I could hook into the snmp set function, like when the var is written, but for now I have working setup. If anyone wants me to post my code I can.
Copied a lot of code from the second example here:
https://pysnmp.readthedocs.io/en/latest/examples/v3arch/asyncore/agent/cmdrsp/agent-side-mib-implementations.html
Learned about MIB compiling and used the mbidump.py tool. Looks like if you don't provide the proper file the old host server might be compromised and it downloads a file automatically...so be careful.
I tried to use send() back to back but it generates an error. I'm very new to network simulation software. Any guidance would be appreciated.
The main problem is that you do not provide code, to your question. Without, that, it's just guessing, so here is mine. You are sending the same packet two times which is NOT possible. You have to create a copy of the packet (with dup()) and send that copy in the second call.
As a general advice: you should do the TicToc tutorial, before going any further into OMNeT++ programming.
I have a syslog server, but I need to find out the URL that has been used to reach my server. For example I have syslog1.example.com and syslog2.example.com, both of which hit the same server, then in the conf file I will filter which URL was set and update a database field based on this value.
I have added fields to the database and using the conf file I am able to manipulate the request, but I need the referer URl. Does anyone have any idea how I can get this.
Obviously I have managed everything else, but have tried little towards this part of the task as I need to know if it is possible and my searches are bringing up results based on Curl which is not what I need. If anyone knows how I can get the URL, it would be most appreciated.
Update
I have a device which has busybox and syslogd installed. I am able to set an address on the device for the syslog, for example 1.1.1.1:514. But I am not able to do anymore on the device other than this.
I have for example 100 devices, 50 are type A and 50 are type B. The issue is that when using 1.1.1.1:514 in every device as the syslog server address, when receiving the device information on the remote syslog server I am unable to differentiate whether the device is type A or type B.
I have the following solution in mind, although there may be another way to achieve this. If I create two subdomains and point them to the same address, ie typea.example.com and typeb.example.com, then in theory in devices with a type A I will set the remote syslog address to typea.example.com:514 and for type B, typeb.example.com:514. Both of these subdomains will point to 1.1.1.1, therefore the syslog information is now being received by devices of Type A and devices of Type B.
I need to now figure out how to in the syslog.conf on the remote server, find out whether the information was received by a device using typea.example.com or typeb.example.com.
The server does not have apache installed etc, however, in PHP for example we can use $_SERVER and normally I would be able to retrieve this information from, $_SERVER['HTTP_HOST']. Is there any way to do this in the syslog.conf on the remote syslog server.
As mentioned this is one solution I have in mind and it may not be the only one. Syslog is new to me and I am currently wrapping my head around this. From what I understand rather than variable or parameters, syslog uses macros. None of the macros provided seem to give me the information I need.
I know I can also set the syslog by doing say
syslogd -R 1.1.1.1:514
Is there anyway here I can include further information for example:
syslogd -R 1.1.1.1:514 type=a
Then I could say use $TYPE to get the value or alternatively add a custom header with the syslog.
As you can likely tell I am racking my brains for solutions and hitting brick walls. Any solution or docs that may point me in the right direction would be greatly appreciated.
Final point would be to mention I am also looking at redirecting the syslog info to a PHP script or a C (I'll say script but I know I am wrong) in order to vet the information there and then insert into the DB.
Quite simply I need a way to differentiate by type A or type B. Hopefully this clears matters up and these are not just the ramblings of a mad man.
I've searched a while for something that can count connected users on wireless interface in Edgerouter Lite and I can't find anything about this in documentation.
I'm wondering if someone hit this problem so far ?
I also using also cacti if someone discovered the OID will be awesome.
You can write a script the logs into the box and gets the information you need. Cacti can call the script during polling.
I've spent hours trying to figure out the answer to this and just continue to come up empty handed. I've setup a XMPP server through OpenFire that is fully functional. My goal with creating the server was placing an alert system for when an event is completed on my server. For example when one of my renders is finished rendering (takes hours, sometimes days), it has the option of running a command when it's finished. This command would then run a .bat file telling a theoretical program to send a message via the broadcast plugin in OpenFire to all parties involved in the render. So it needs to be able to receive parameters such as %N for name of the render and %L for the label of it.
I've located two programs that do exactly what I'm looking to do but one does not work and from the sounds of the comments may have never worked and the second one is seemingly LINUX only. The render server is Windows as is the OpenFire server so naturally it would not work. Here are the links though so you can get an idea.
http://thwack.solarwinds.com/media/40/orion-npm-content/general/136769/xmpp-command-line-client/
http://manpages.ubuntu.com/manpages/jaunty/man1/sendxmpp.1.html
Basically the command I want to push is identical to that of the first link.
xmppalert.exe -m "%N is complete." %L#broadcast.myserver
This would broadcast to everyone in the labels Group that the named render is complete.
If anyone has any idea how to get either of the above links working, know of another way or simply have a better idea on how to accomplish what I'm trying to do please let me know. This is something that has been eating at me for 2 days now.
Thanks.
you can take a look at PoshXMPP which allows you to use XMPP from the Powershell.
