NAME
netdump - send oops data and memory dumps over the networkSYNOPSIS
/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.
