netdump-server
NETDUMP-SERVER(8) System Programs NETDUMP-SERVER(8)
NAME
netdump-server - handle crash dumps over the network
SYNOPSIS
netdump-server [--port portnumber]
[--concurrent number]
[--pidfile path]
[--daemon]
[--help] [--usage]
DESCRIPTION
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 timestamped directory in /var/crash. The server can also run scripts when some events happen.
OPTIONS
--port portnumber
Specifies the IP port number for the netdump server to listen to. The default is 6666.
--concurrent number
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.
--pidfile path
Store a pidfile. The default service uses /var/run/ttywatch.pid. The default is not to write a pidfile.
--daemon
ttywatch should background itself and run as a daemon.
EXAMPLES
netdump-server --daemon
This launches the netdump-server and puts it in the background, listening for crashed clients.
EXIT STATUS
Exit status is 0 for a clean exit and non-0 for a non-clean exit.
FILES
/etc/netdump.conf
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 pidfile.
/etc/init.d/netdump-server
An init script to start a default system installation of netdump-server. This is normally turned off by default; use the command
/sbin/chkconfig netdump-server on
to enable the netdump-server service.
/var/crash
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 crash.
/var/crash/scripts
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 argument.
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 booted up.
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 without 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.
