Re: snmpd&/dev/null error

Fortunately the list administrator did not delete your message as spam
because most of list members would not be able to read Chinese:)

If you look at the SYNOPSIS of snmpd:
snmpd [OPTIONS] [LISTENING ADDRESSES]

The "-Lf" option is only supposed to be followed by a single file. If
you use "snmpd -Lsd 篓CLf /var/log/snmpd.log /dev/null" then my guess is
that snmpd thinks the [OPTIONS] part has ended after "-Lf
/var/log/snmpd.log" and consider whatever follows as [Listening
Address]. In your case the listening address would be "/dev/null". Since
the Unix domain is assumed if the first character of the
<LISTENING-address> is '/', and you were running snmpd as root so it can
do anything, including changing /dev/null from character device into an
unix domain socket.

Thanks
