NETCONSOLE-SETUP(8) netconsole-setup's Manual NETCONSOLE-SETUP(8)

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.
