Subject: How did you realised an asyncron job
Reply-To: [EMAIL PROTECTED]
I am trying to start on LInux an asyncron job.
Here is how I tryed and it didn't worked:
$proces=sprintf('wget '.
'"%sbackground.php?payee=%s&file=%s&type=profile"',
$SITE_BASE, $HTTP_SESSION_VARS['payeeID'],
$file);
$fp=popen($proces, "r");
print "Forking process: $proces";
exit;
Any suggestions?
I would really apreciate the help.

I don't need 1000 times at once...
But I want to check ports periodically...
For example, every 2 minutes I must check 10 ports... So 1000 times * 2 / 10
= 200 minutes = only 3 hours... :(
So, in one week, I'll have 7*24*60*10/2=50 000 connection in LISTENING
state!
To close these connection, I have to restart apache service... :(
Best regards,
Sherry.

Well, two things come immediately to mind. Using sleep() or
continuously cycling and checking to see if the current time matches
whatever time criteria you need (8:00am, minutes divisible by 10, etc).
Then you don't need to hammer the sockets 1000+ times per second.

Ok, I see the nature of the problem now.
You probably get all these SYNC_SENT and TIME_WAIT because
the hand shake is not properly done between the machines.
SYNC_SENT means that the local socket is trying to
established a connection.
TIME_WAIT indicates that no shutdown is (yet) recived
from the other end.
(This how is the classical SYNC-attack works, i.e.
open a port on the remote machine, and drop the
connection without picking up the SYNC_SENT pakages,
leaving the remote server port in TIME_WAIT - this way
one can "eat up" all ports on a remote machine.)
In these cases it very useful to have a look at the socket
state at the remote peer to determine weather the sync
package was received or not.
Firewalls can sometimes screw up this kind of traffic,
and drop SYNC packages in both direction without no good
reason - the firewall log may complain that the package
"looks like" it was forged, but in fact it is just fine.

Errr...
I have so bad English??? :)
I doesn't mean 1000 times per second!
I mean 10 times per 2 minutes... So, in 3 hours I'll have about 1000 open
connections!
And the main problem is these opened connections...
Best regards,
Sherry.

BAT, I have tried fsockopen and socket_connect on two machines.
First comp has Kerio firewall, and second hasn't any firewall.
Problem persists on each machine.
And I can't look at remote socket... Comp on other end just doesn't exist...
:)
After timeout (when using fsockopen) SYNC_SENT connection closes normally,
but LISTENING connection remains.
Best regards,
Sherry.

LISTNING is the state a server (listner) normally
should be in, or do I miss something here?
That you can replicate it on anotehr machines, does not
say that very much. It can still be 1) the network, 2)
wrong handling of sockets in the program, 3) something
else.
I guess I need to have a closer look at your first mail
again to better understadn the problem, but right now I
am bit sleepy so that will have to wait until tomorrow.

Heh...
I mean not LISTENING on 80 port! I mean LISTENING on each of these
connections!
For example, My IP is 192.168.18.1 and I try to check port 21 on IP
192.168.18.33.
When I call fsockopen, apache open 2(!) connections:
192.168.18.1:3256 192.168.18.1:0 LISTENING (3256 -
random port on my IP)
192.168.18.1:3256 192.168.18.33:21 SYN_SENT
When timeout occurs, second connections disappeared, but first exist until
apache restart!
And I don't do anything else! Just call fsockopen... :(
Best regargs,
Sherry.

Trevor,
I think I have this one licked. Not tested yet, but a little bit of
javascript and it should work like a dream.
Ta for helping me focus.
