netdump

NETDUMP-CLIENT(8)						  System Programs						 NETDUMP-CLIENT(8)

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.
