    Nice summary.

    You have to install the agent, it's not stock.  And it's not so much that
    the world-writable string is "public" as it is that there isn't one.
    You'll get write access no matter what community name you use.  MS made
    improvments under NT, 'cause it was the same, but it's still broken in 9x
    AFAIK.  Check:

    I'm sure I won't be the only one to point out that the SNMP problem is
    part of the OS (Solaris 2.6 and later) not the hardware. I suspect Sparc
    OpenBSD will be OK. :)
    
    Solaris 2.6 was the first version (I believe) to install an SNMP agent as
    part of a standard Solaris install.  There were hard-coded SNMP community
    names that gave write access.  There was also a patch. Check out:
    http://www.securityfocus.com/vdb/bottom.html?vid=177
    
    At a previous job, Lucent installed a remote access server and left the
    SNMP write community as public.
    
    I don't think SNMP issues have gotten as much attention as they should.
    There are some really bad things one can do.  Depending on platform, you
    can start and stop programs, kill processes, download all passwords, shut
    down the boxes, change hardware settings, all without any loggin in most
    cases.
    
    You really want to not have this problem.
