SNMP probers

[randy () psg com (Randy Bush)]

What do folk do about persistent SNMP probers?  I.e. j random clueless sites
which keep querying one's backbone router(s).  E.g. this morning I get the
NOC shift change report with the folk hammering on our routers as if we were
stupid enough to use 'public' as the community string.

> mae-east      Bad community string from 194.168.51.4
> mae-east      Bad community string from 193.38.113.216
> mae-west      Bad community string from 202.85.254.5
> mae-west      Bad community string from 206.79.240.190
> mae-west      Bad community string from 193.38.113.216
> pdx           Bad community string from 204.119.24.200
> pen           Bad community string from 164.117.144.245
> pen           Bad community string from 193.38.113.216
> paix          Bad community string from 204.79.240.190

So every day some poor NOC person has to search these folk down with the
great tools we have, send email, get told they're nazi idiots, ...

So what do folk do about this?
