Linux Server: Automatic Restart w/o program crash?

[The Hunter]

Hi. I've got my Linux server up and running quite nicely (check it out at 64.246.16.4:27966), but it crashes every few days (although without any seeming regularity). I've got my startup script set up to check if the program crashes and restart it if it does, but sometimes the server will crash but the program will not, and therefore the script doesn't restart it. I was wondering if there were anyway to restart the server automatically in this case.

 

Any ideas?

 

I'm running 1.03 on Redhat 7.1.

 

Thanks for any help you can offer.

Check out this Thread. There are alot of different restart scripts here maybe one of them will help you.

This may exactly what your looking for. your gonna have to change some of the varibles but it should work with jedi.

#!/usr/bin/perl -w
#
# assign the varibles for your setup here and run it from cron
#
use Socket;
$proto = getprotobyname('udp');
$server = sockaddr_in ($game_server_port, inet_aton($game_server_ip));
open (STDLOG, ">>$quake_check_log") || die "can't open $quake_check_log: $!";
print STDLOG `date`;
socket (QUAKE, PF_INET, SOCK_DGRAM, $proto) || die "problem opening socket: $!";
connect (QUAKE, $server) || die "problem connecting to server: $!";
$data = "\xff\xff\xff\xffgetstatus\x0a\x0b\x0c\x0d";
sleep(1);
send (QUAKE, $data, 0);
print STDLOG "Doing a Quick Status on Server at IP $game_server_ip port $game_server_port\n\n";
eval {
$SIG{ALRM} = sub { die };
alarm 3; # this should be plenty of time
$getstatus = recv(QUAKE, $GETSTATUS, 4096, 0) || die "There was a problem in recv(): $!";
alarm 0;

I've been using the startjk2/holdjk2 method in described in the Linux HOTWO thread. Works nice.
