Installing Soap-Lite modules for Linux

  • apt-get install libsoap-lite-perl -s
  • Note: ActiveState Perl for Windows already includes Soap-Lite


root@mylvs01:/var/www/mylvs/ws/cgi-bin# chmod 777 lvs.cgi
root@mylvs01:/var/www/mylvs/ws/modules# chmod 777 lvs.pm


  • Note: The webservice requires mylvsmon to run


From the client:

#!/usr/bin/perl -w
use SOAP::Lite + qw/ trace /;
my $soap = SOAP::Lite
  -> uri('urn:lvs')
  -> proxy('http://ws.mylvs.foo/cgi-bin/lvs.cgi');
#my $result = $soap->REQUESTWEIGHTSTATUS ();
#my $result = $soap->WHATISMYIP ();
#my $result = $soap->REQUESTWEIGHTDOWN ();
my $result = $soap->REQUESTWEIGHTUP ();
unless ($result->fault) {
 print $result->result();
} else {
  print join ', ',
    $result->faultcode,
    $result->faultstring;
}
