`Following on from Michael Zalewski's recent SNMP post, here's an issue i  
noted on two AIX systems.  
  
NOTE: This was seen on both AIX 4.3 and 4.2.  
  
It appears that on the above releases of AIX, the SNMP daemon is enabled  
by default and two community names are enabled with read/write privileges.  
The community names are "private" and "system", but are only allowed from  
localhost connections. Nevertheless, a local user may install an SNMP  
client, and modify sensitive variables.  
  
Excerpt from /etc/snmpd.conf:  
  
<snip>  
  
# 2. Set the community names and access privileges for hosts that can make  
# requests of this snmpd agent. Define these restrictions as follows:  
#  
# community <name> <address> <netmask> <permissions> <view name>  
  
<snip>  
  
community public  
community private 127.0.0.1 255.255.255.255 readWrite  
community system 127.0.0.1 255.255.255.255 readWrite 1.17.2
