NeDi Software Specific > Discovery

Discovery ignoring netfilter?

(1/2) > >>

pato:
Hi all
I'm using the current Nedi 1.6.100p4, which I've installed two days ago.
This all worked fine and after some time I even discovered why the discovery took hours instead of minutes (ssh access wasn't allowed).

What disturbs me though, if I run a ./nedi.pl -p -v, I can see that nedi sends my snmp v2 strings to devices that aren't in the filter list that I've configured. Don't have any snmpv3 ones. Not sure if it also does the same with my ssh credentials.

Is this by (undocumented) design or a bug?
My netfilter:
# Only discover devices where ip address matches this regular expression.
# This way NeDi will not send any login credentials to rogue/evil devices.
;netfilter      ^192\.168\.0|^172\.16
netfilter       ^192\.168\.0|^192\.168\.62

# To avoid networks
;netfilter      ^(?!192.168.1).*$
netfilter       .

And I see in the debug that it tries to connect to 10.10.2.50 (for example), which it shouldn't based on the netfilter.

i'm not sure if you realy need to escape the dots.

i use these filter and it works perfect.

pato:
That's how it is shown in the config file.
And you are sure that the credentials aren't sent to other devices if you do a -p discovery?
You need to enable -v (verbose) mode to actually see it.

ascii:
i*m quite sure.
i keep forgetting to add new subnets to the filter and NeDi will not discover them since they are out the netfilter range.
after i add them than the discovery works

pato:
The thing is, I believe they will not show up in the GUI because of the filter, but they still get sent the credentials in the -p discovery.
