netdump-server - handle crash dumps over the network
netdump-server [--port portnumber]
Listens to the network for clients that crashes and uses the netdump protocol to recieve a
memory dump and a stack trace. The memory dump and oops message are stored in a times-
tamped directory in /var/crash. The server can also run scripts when some events happen.
Specifies the IP port number for the netdump server to listen to. The default is
You can limit the amount of concurrent dumps being done at any one time. If more
clients than the specified maximum connects at one time the last ones will just be
logged and then rebooted.
Store a pidfile. The default service uses /var/run/ttywatch.pid. The default is
not to write a pidfile.
ttywatch should background itself and run as a daemon.
This launches the netdump-server and puts it in the background, listening for crashed
Exit status is 0 for a clean exit and non-0 for a non-clean exit.
A configuration file read by netdump-server on startup. It is a "key=value" style
file. Currently it supports the options: port, max_concurrent_dumps, daemon and
An init script to start a default system installation of netdump-server. This is

to enable the netdump-server service.
The main directory where the crash dump files are stored. Each dump is put in a
subdirectory named with the ip of the crashed machine and the date and time of the
This directory can contain scripts that are run at various times. They all get
passed the ip of the crashing machine as the first argument, and each one except
netdump-start gets the directory that the dump is written into as the second argu-
netdump-start - This is called when a client connects to the server to tell it that
it has just started the netdump client. This normally means that the machine just
netdump-crash - This is run when a client reports that it has crashed. If it
returns a non-zero value the dump request will be ignored and the client will be
told to reboot immediately
netdump-nospace - This is run when there is not enough diskspace for the dump of
the crashed machine. If this script exits with a non-zero return value netdump-
server will try once again (but only once) before giving up the dump. If this
script exits with a zero return value, netdump-server will reboot the client with-
out performing a dump.
netdump-reboot - This is run when netdump-server is finished with a client and is
about to tell the client to reboot itself.
