NSE scripts for SNMPv3?

Posted by Johan Kuuse on Oct 03

Hi, my first mail to this list,

I have used (and modified) quite a few NSE scripts for SNMP.
Anyhow, AFAIK, all SNMP scripts (except "snmp-info") are limited to SNMPv1
and SNMPv2c:

nmap --script-help=snmp* | grep -B3 -A1 -i v3
----------------------------------
snmp-info
Categories: default version safe
https://nmap.org/nsedoc/scripts/snmp-info.html
Extracts basic information from an SNMPv3 GET request. The same probe is
used

Regarding NMAP Retrigger for snmp-sysdescr

Posted by Ramu Burra via dev on Oct 31

Hi Daniel & NMAP team,

I hope this email finds you well.

I'm writing to inquire about the specific behaviour of Nmap's SNMP-SYSDescr query in situations where the target device
responds intermittently.

I'm particularly interested in knowing if there are any specific configuration options or techniques that can be
employed to increase the likelihood of successful SNMP-SYSDescr queries, especially when dealing with...

Re: Regarding NMAP Retrigger for snmp-sysdescr

Posted by Daniel Miller on Oct 31

Ramu,

Nmap's snmp-sysdescr script currently uses a 5-second timeout and attempts
only once to send the SNMPv1 request. We agree that this could be improved
to provide better reliability. I will investigate further and respond again
with specific suggestions.

Dan
