NAME

netdump - send oops data and memory dumps over the network

SYNOPSIS

/etc/init.d/netdump (start|stop|status|restart|propagate)

DESCRIPTION

Loads and configures the netdump kernel modules. Once these are loaded, when the kernel crashes it will send the oops message and a dump of physical memory to the machine that runs the netdump-server. This can then be used to debug the problem using gdb and a kernel image.

OPTIONS

start: Starts the netdump client service. Loads the kernel modules with the right options.
stop: Unloads the kernel modules.
status: Shows the status of the netdump client
restart: Restarts the netclient modules with new configurations.
propagate: Sends the ssh public key needed to update the random key for each netdump session to the netdump server.

FILES

/etc/sysconfig/netdump

Configuration for the netdump client. You need to at least specify the address of the machine running the netdump server here.

/etc/sysconfig/netdump_id_dsa.pub

Public key for this machine. Used by the server to authenticate the client. This must be installed on the server, possibly by using the the propagate capability of the netdump init script, which does:

cat /etc/sysconfig/netdump_id_dsa.pu | ssh netdump@$NETDUMPADDR cat '>>' /var/crash/.ssh/authorized_keys2

Where $NETDUMPADDR is the ip or name of the machine running the netdump server.
