.SH NAME
|
||||
osasnmpd \- IBM OSA-Express network card SNMP subagent.
|
||||
.SH SYNOPSIS
|
||||
\fBosasnmpd\fR [-h] [-v] [-f] [-l \fIlogfile\fR | -L] [-A] [-P \fIpidfile\fR]
|
||||
[-x \fIagentx-socket\fR]
|
||||
.SH DESCRIPTION
|
||||
\fBosasnmpd\fR is an SNMP subagent for the net-snmp 5.1.x package.
|
||||
It supports the MIBs provided by an IBM OSA-Express network card.
|
||||
The subagent communicates via the AgentX protocol with the snmpd daemon.
|
||||
Hence the snmpd daemon must be already started on the same system before
|
||||
osasnmpd can start successfully.
|
||||
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
\fB-h\fR
|
||||
Print usage message and exit.
|
||||
|
||||
.TP
|
||||
\fB-v\fR
|
||||
Print Version information and exit.
|
||||
|
||||
.TP
|
||||
\fB-f\fR
|
||||
Don't fork() from the calling shell.
|
||||
|
||||
.TP
|
||||
\fB-l\fR \fIlogfile\fR
|
||||
Logs all output from the subagent (including stdout/stderr) to
|
||||
\fIlogfile\fR.
|
||||
.br
|
||||
(By default logfile=/var/log/osasnmpd.log)
|
||||
|
||||
.TP
|
||||
\fB-A\fR
|
||||
Append to the logfile rather than truncating it.
|
||||
|
||||
.TP
|
||||
\fB-L\fR
|
||||
Print warnings/messages to stdout/stderr.
|
||||
|
||||
.TP
|
||||
\fB-P\fR \fIpidfile\fR
|
||||
Save the process ID of the subagent in \fIpidfile\fR.
|
||||
|
||||
.TP
|
||||
\fB-x\fR \fIagentx-socket\fR
|
||||
Uses the specified socket as AgentX connection rather than the
|
||||
default '/var/agentx/master'. The socket can either be a Unix
|
||||
domain socket path, or the address of a network interface.
|
||||
If a network address of the form inet-addr:port is given, then
|
||||
the subagent will use the port specified. If a network address
|
||||
of the form inet-addr is given, then the subagent will use the
|
||||
default AgentX port, 705.
|
||||
The agentx sockets of the snmpd daemon and osasnmpd must match.

|

* net-snmp AgentX support must be enabled to allow the

* subagent connecting to the master agent (snmpd).
