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. The
NETDUMPKEYEXCHANGE

variable in
/etc/sysconfig/netdump

can be set to
none

to disable security features of netdump. If
none

is specified, the server must be configured not to use security.

/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 if security is enabled, possibly by
using the the propagate capability of the netdump init script, which does:

cat /etc/sysconfig/netdump_id_dsa.pub |
ssh netdump@$NETDUMPADDR cat ‘>>’ /var/crash/.ssh/authorized_keys2


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