Thanks for the reply ahmad! I was looking at alarm() and it appear to be a solution to my problem, however it breaks my code. I used like that... 
eval {
local $SIG{ALRM} = sub { die "alarm\n" };       # NB \n required
alarm 5;

my $sock = new Net::SOCKS(socks_addr => $socksserver, socks_port => $s
+ocksport, protocol_version => 5);

alarm 0;
};

die if $@ && $@ ne "alarm\n";       # propagate errors

if ($@) {
        print("\nTIME-OUT\n");
}
    else {

my $con = $sock->connect(peer_addr => '10.1.1.3', peer_port => 23);

#other parts of my code.
}

Without this alarm() the application runs without errors, but with this new alarm() code I'm getting errors: Global symbol "$sock" requires explicit package name at ./test.pl line 48. Execution of ./test.pl aborted due to compilation errors. I have the main code, inside this main code I call 3 threads and inside this threads I call a function to test the connectivity, this function is where this example of code is located. I don't want to die(), well, I can call die(), but I can't exit the application, in the case of a timeout I just want to call "return" or something like that to return from this function to the previous function (the one used when I called the tread). Can you please give a help how to fix this example of code with alarm()? Thank you
