Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Here is a .pl file =, in this file i need to pull out some static variable value into a text file. so all the static var info will be retreive from the text file. To retreive the static info from the text file, there is another file which store the function to load the static info into the cgi file. emm sorry can one package call to another package?

here is the the part of the

--------------------------------------- package IMSLook; use Socket; use CGI qw/:standard/; require ""; require ""; require ""; # ----------------------------------------------------------# global v +ariables # ----------------------------------------------------------my %server +con = &LoadConfig::LoadConfig("server.conf"); my $hostname = $servercon{'hostname'}; my $port = $servercon{'port'}; my $password = $servercon{'password'}; my $logdir = $servercon{'logdir'}; sub IMSConnect { my $response; my $iaddr = inet_aton($hostname) || die "no host: $server"; my $paddr = sockaddr_in($port, $iaddr); my $proto = getprotobyname('tcp'); # Open socket connection to the server socket($sock, PF_INET, SOCK_STREAM, $proto) || die "socket: $!"; connect($sock, $paddr) || die "unable to connect"; select($sock); $| = 1; select(STDOUT); &SOCKETread($sock); &SOCKETwrite($sock, "LOGIN $password WRITE\n"); $response = &SOCKETread($sock); if ($response =~ /.*OK.*/) { &TaskLog("IMSLook sub::IMSConnect: Successfully connected +to IMS\n"); return 0; } &TaskLog("IMSLook sub::IMSConnect: Access denied to IMS, possibly +invalid password\n"); return 1; } Here is the part for the function : -------------------------------------------------- package LoadConfig; use IO::Handle; sub LoadConfig() { $config_file = $_[0]; #open a file handle open(MYHANDLE, "<$config_file") or die "could not open file"; while (<MYHANDLE>) { chomp; s/#.*//; # no newline s/^\s+//; s/\s+$//; next unless length; my ($var, $value) = split(/\s*=\s*/, $_, 2); $User_Preferences{$var} = $value; } return %User_Preferences; } # ~LoadConfig() 1; here is the the part of the text file name Server.conf: -------------------------------------------------------- hostname="" port="4200" password="p" logdir="C:\\tempperl" host='' host392=''
the problem is when i run, the apache server error log giving me the error that say i dun supply the host name for them. It mean the $hostname in (sub IMSConnect) didn't get any value can anyone check it for me. Thank you

    Your data file has quotes around the variables. You never strip the quotes, or do something with the double backslash for that matter. "" is not a valid hostname, because quotes are not allowed in a hostname. Nor is "4200" an integer. Or "C:\\tempperl" a directory.

    The error log says you didn't supply a host name because of your bogus die message. Fix your die message and you'll get better error messages.

    Please use <code> tags around your code - it's not readable without, as you might be able to see...

    Update: Now that the <code> tags are added, it seems that you should have the quotes around the hostname too in the $hostname variable. Please try to die with $hostname and not $server to see what you really have in that variable. I don't know what exactly the inet_aton function does if it gets bogus input, but that might be the problem.
    use signature; signature(" So long\nAlfie");
