Network scan tool.

2016-06-07 Thread Luis Zárate 
Hi,

With your deadline is too difficult (impossible), but if you are a crack in
django and celery and nmap this tool could be useful
https://pypi.python.org/pypi/python-nmap

You'll probably need Celery to process the commands for adding/removing
hosts from the backend and other management tasks.

Not to disillusion you, but IMHO writing such an application within two
weeks is highly, highly improbable. Since you have a tight deadline, I'm

You might want to consider integrating with an existing monitoring system
(such as Nagios, monit, etc.) or perhaps a configuration management system
such as Ansible, SaltStack, Puppet, or Chef for communicating with the
hosts and handling discovery. It's unlikely that you'll reinvent the wheel

Django actually has a very small part to play in this entire application.
You'll probably need Celery to process the commands for adding/removing
hosts from the backend and other management tasks.

If it were me, and since you have all Linux hosts, I would start with
Ansible (and Cobbler for the DB integration). I have limited experience
with it (I'm still researching it for my own purposes), but it should be
able to handle all of the requirements except for the last couple, which

Re: Network scan tool.

There is two way to monitor the data.
Either passively, listening for each host saying hello on the network
or actively, probing for host at regular interval [1].

First way look like difficult as in requiring cooperation from diverse
host and relying on protocol like SNMP. Or you could listen for DHCP
message on the network.

The other way require to run a script at regular interval. For that
job, I would suggest Celery. Cron is the unix job for that tool but
celery is a python solution and integrate nicely with django.

Your project have quite an overlap with nagios. Especially for point
3, if you can interface with tools made to talk to nagios from client,
it will save you lot of trouble.

[1] If you want real time, there is an anecdote about diablo. The game
was turn-per-turn but the publisher wanted real time. Dev got twice
the money to turn it into real time. Dev simply reduced turn to 200ms.
Job done.

Network scan tool.

2016-06-07 Thread Mahesh Kss 

Hi all,


Need some of your thoughts for the below mentioned exercise. I am planning 
to do it using Django. But I am not sure where i can place the python 
script which monitors the network for connected hosts.

Kindly share your thoughts and questions. I need to complete this as soon 
as possible(max 2weeks from now).


Scanning tool:

added host in network (by maintaining new and old host list).

> The python script should then scan all the discovered systems in network

On each system, list of all major softwares found along with installation 
directory, version, license expiry date, etc.
