#3256 — Can you advice a Python library to query a lan subnet with SNMP and collect MAC addresses of nodes?

Hello All,
in my specific problem I will be happy of a response where possible
to:

1. distinguish different operating systems of answering nodes
2. collect responses of Wyse thin-clients with "Thin OS" to get node
name and MAC address in particular

Thanks a lot in advance for any sharing / forward to documentation,
products in the area.

I think for your interest, if what you described is not a part of your 
software you are doing but only a specific task, you could use some 
network scanning tools like nmap to achieve your goals.

there is also a module called pysnmp and you can look into it to see if 
it meets your need.

Thanks Frank! I've browsed pysnmp as you kindly adviced, now looking
also into http://pynetsnmp.sourceforge.net/

This is 6-7 year old stale memory (and dont want to start a flame war
but...)
Last I looked at the snmp modules in python I vaguely remember that
the perl modules were so much more feature complete that I had to
switch to perl even though I am generally uncomfortable with perl.

Hello and thank you All!
I've solved my problem as follows:
1. installed nmap
2. wrote a python script calling nmap nmap -sP via os.system and
redirecting output to a file
3. read results file and made a further processing to get exact
filtered records with MAC addresses I needed

Kindest regards Aldo

I don't know if it's significant, but if I want to process a command's
output using Python, I'll generally use:

nmap -sP | /path/to/script.py

rather than os.system() and temporary files. YMMV though.

Isn't it better to use subprocess.Popen and read stdout/stderr
directly? Should be much more convenient than temporary files.
