NAME

straps - A simple SNMP trap multiplexer.

SYNOPSIS

straps [ port ]

DESCRIPTION

The straps trap daemon listens on the snmp-trap port (usu
ally port 162/udp) for incoming SNMP trap or inform mes
sages and forwards them to all connected clients (like
scotty). The optional port argument allows to use the straps daemon to forward messages received on a non stan
dard SNMP trap port. However, port numbers below 1024 will
be rejected.

Clients connect to the straps daemon by opening the AF_UNIX domain stream socket /tmp/.straps-port. Thus, the
default AF_UNIX domain stream socket is named
/tmp/.straps-162.

Received messages are forwarded using the following for
mat:

4 byte IP address of the sender (network-byte

order).

2 byte Port number of the sender (network byte

order).

4 byte Length of the trap message (host-byte

order).

n bytes The trap message itself.

The straps daemon must be installed setuid root because normal operating systems require root permissions to open
the standard SNMP trap port 162/udp. The straps daemon rejects all port numbers below 1024 in order to protect
the system security.
