NAME

netdump − send oops data and memory dumps over the network

SYNOPSIS

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

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.

FILES

/etc/lkcdutils/netdump

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

/var/spool/crash/.ssh/id_dsa.pub

Public key for this machine. Used by the server to authenticate the client. This must be installed on the server, typically done by a command like:
cat /var/spool/crash/.ssh/id_dsa.pub | ssh root@$SERVERADDR cat ’>>’ /var/spool/crash/.ssh/authorized_keys2
Where $SERVERADDR is the ip or name of the machine running the netdump server.
