So now let's talk about this S&P protocol, S&P simple network management protocol.
So what is the purpose of this Portakabins?
It is used to manage the but getting that information.
So if you have 100 computers, you cannot go to each and every computer to get information.
So it is protocol.
You can just get that the way this information is in this protocol, they are going to each and every
computer.
And Rotar implements this service in this Rotar, this service is implemented, and what this protocol
does is it combines management software and master computer.
So you are the head of a company and this management situation software in a computer that you are to
monitor, to operate.
If you have a computer, you can install this management software and you need to ensure the agents
in our computer he can install this weather accurately and often.
Agents in our computer then as an MP helps to get CPU's discusses and gets jealous, etc..
So from this administration, you are the computer's CPU usage are discuses or whether they are on or
off.
So it's very easy sitting in your place.
You can just get the information of our computers and this service runs on your reports once you show
up.
And so this is an easy UDP protocol and this one won't put you use it for my administration software
asking for the agent about the information and these agents since the responses, I mean, the status
or any information, why are these 162 port?
So people are open under the service.
Those are the Europeans, 161 and 162.
So this of is very important in that organization.
So I was referring to I am an employee and I did not do the work and I was simply watching the Netflix.
So the I how the computer given by the organization and they can the preinstalled these employee management
software and if I watch any movies or Netflix, then immediately the network bandwidth goes high and
it will raise the alarm for the.
So admissions come to.
So what you're doing with this hypothetical when bandwidth, so what you're using for whether you are
already moving or watching, so that in that case, it strictly restricts an employer to do the work.
That is one plus point at all.
So it's not the point because this product is used for getting this information.
But some applications are being made like employee management software to get even to watch even what
they're like screen sharing.
But it's all about privacy.
But in office hours, you should not do some movies watching all those things.
Right.
So this is what is best for the software.
And it's a piece of three versions of the note.
And those two options are watching one, two and three.
And this is also contain possible like strings and testing so you can compress information.
So these are sort of strings are you can also call them as passwords.
And these passwords are public and private by default.
And this I want to talk about first versions, version one, 2003 and the introduction one, and to
see the things these passwords are not.
And so they will transfer the data in appendix format.
So if anyone logging in to this router with this community string's, any attacker can do the math against
this plaintext data.
And in the plain text data, you can see the strings very clearly in this person wanted to see.
So in version three, they have implemented the encryption, but so many us in organizations are using
the want to see because they did not have the if you find out that actually wanted to see, you can
simply report that these are not updated.
You need updated version three.
And the different parts of the public and private, so this I can access some major, like small information
using the public Streamcast public and with this private string I can access and that data of our computers
so that our IP address and interface status, whether these are personal, are those data with the public.
I just get the right information are like just basic information.
And these defaults, these are the default passwords inserted when the road is manufactured and these
passwords are not changed when the shelter set up.
That as an officer is most of these will be public or private.
And if you found out that in a in a pinch that these are the public and private, you need to report
that you should change the community strings to somewhere else and everything is OK.
So if you want to this, you need to pass some of the correct structure and we need to query all the
information using this object.
So this object is called out to tree, and this is represented by this one.
This is a sample image.
And first one is root and the user or the Internet.
And from here on was the branching goes on the tree management expert in the private and one of the
information agencies IP interface system.
So if you want to access the system's information, what you want to do is you need to use some tools
to articulate a simple pattern problem.
So we'll be doing this in a punishing section.
So I would just say you could access these variables are like informations are you need to do is walk
down from top to bottom of the tree and put the dot in between them.
So if I want to access the interfaces, what I want to do is I want to create a screen.
It says that one that one dot, dot, dot, dot so that users interface for.
So if you pass this one three, one does not want to do a tool like a set of piguet.
And with the public or private string, if you know them, then you could easily get the information
of the interfaces of the computer.
And in the same way, if you access this one, not one, not one, not one, not for you get the IP
address of the commission or you can get all the IP addresses of our machines.
So in this way you can just construct a tree like structure and you can just go with this data format.
So one more thing I want to tell is there is another translator called Information Base.
And what this does is this might be the translations for these variables.
So if I say interfaces, if I want to pass this one three six one one one two, it uses me interface
so I can check these translations for this, uh, or do three.
That is of the identifier three.
So many wonders how their own message information, Bush's support, if you can see the enterprise level,
that if you want to access this, the Sisco's number is nine from this, nine on what you can exoduses
course information from in the several Microsoft Office, three, one one and the same with Juniper
and maybe has a 266.
So this one does have the automated information base.
But for the most of the time, these will be the same.
The normal information you get are the same.
So this is all you need to know.
You need to know about this.
I said I'm sorry.
Yes, I know that this is a message and punishment, not it's management information that's very confusing
and saying sorry for that.
Just this is the management information with each one that had different management information, which
is.
