NAME

       netconsole-setup - Dynamically configure Linux netconsole

SYNOPSIS

       netconsole-setup [[+][target-port]@]target-host ...

DESCRIPTION

       Netconsole  is  a  Linux  kernel  module  that  sends all kernel log messages over the network to another
       computer.  It was designed to be as instantaneous as possible, to enable the logging  of  even  the  most
       critical  kernel  bugs.  It works from IRQ contexts as well, and does not enable interrupts while sending
       packets.  Due to these unique needs, only IP networks, UDP packets and Ethernet devices are supported.

       netconsole-setup eases the configuration of the netconsole by just  taking  the  target  hostname  or  IP
       address.  It determines all the needed configuration values from the running network device (like network
       interface, target IP and MAC address).  Multiple target  hosts  can  be  specified.   Each  host  can  be
       prefixed with a target port and a plus sign to enable extended console support.

OPTIONS

       +      if present, enable extended console support for this host

       target-port
              port for logging agent (kernel default is port 6666)

       target-host
              hostname or IP address for logging agent

EXAMPLES

              netconsole-setup loghost

       sends all kernel log messages to host loghost.

              netconsole-setup +4444@loghost

       sends all kernel log messages to host loghost on port 4444 using the extended console support.

              netconsole-setup loghost1 4444@loghost2

       sends all kernel log messages to host loghost1 on the default port and to host loghost2 on port 4444.
