Hi Tachyon,
I have try what you recomended here is the script I follow. But there is some error. Here is the script.
My server B have Apache cgi install. And this is the script i put in. name : servert.pl
#/usr/bin/perl -w
use strict;
use CGI;
my $q = new CGI;
print $q->header();
my $err = do_something();
print $err ? $err : "OK";
sub do_something {
for (my $i=0;$i<20;$i++ {
print "\7";
}
}
Then the server A i have put in the script name clientt.pl inside one of the folder.
#!/usr/bin/perl -w
use strict;
use LWP::Simple
#while (1) {
# if ( some_event() ) {
my $response = get('http://192.168.0.123/cgi-bin/servert.pl');
warn $response =~ m/OK/ ? "Notified server b OK\n" : "$respons
+e\n";
# }
sleep 10;
#}
# check for some event
#sub some_event { ... }
I have take out the while and the sub function because i just want to test whether it can call to the server B. but it reply me with the error below, even i didn't remark it.
Use of uninitialized value in pattern match (m//) at clientt.pl line 1
+0. <br>
Use of uninitialized value in concatenation (.) or string at clientt.p
