Windows Agent no connect to OCS Inventory Server

I use OCS Inventory Server and I installed OCS Inventory Agent on PC with Win7. From this PC I can open site and default agent configuration with server address: In agent log Isee this Error 500:

Starting OCS Inventory NG Agent on Tuesday, October 09, 2018 17:14:52.

On Server in Apache Error log I see this:

In OCS Server Activiny log is clear.

Hi @raze,

have you tried to temporarily remove the plugins scripts from the following folder and restart an inventory ? (do not remove the file "DO_NOT_REMOVE.txt" from this folder)

C:\Program Files (x86)\OCS Inventory Agent\Plugins\

I have the same problem and I do not find the solution eithercrying

I have a new installation OCS Inventory Server 2.5 in Ubuntu Server 18.04 with the same problem with 2.4 and clients in Windows 10 PRO 64Bits , ERROR *** AGENT => Failed to send Inventory <HTTP Status Code #500>, the only temporary solution that I have found is to comment # line 50 of the file Update.pm


Line 48:  set_category();

Line 49:  set_asset_category();

Line 50:  #set_saas();

But in doing that, I think the plugins stop working.

Please, it is important to solve it, if someone knows a permanent solution that explains it. Thank you.

i tried to define the "missing subroutine" inside the Update.pm file:

sub set_saas{
    my $dbh = $Apache::Ocsinventory::CURRENT_CONTEXT{'DBI_HANDLE'};
    my @saas_exp = get_saas();
    my $saas_en = 0;
    my $sql;
    $sql = $dbh->prepare("SELECT ivalue FROM config WHERE config.name='INVENTORY_SAAS_ENABLED'");
    while (my $row = $sql->fetchrow_hashref()){
        $saas_en = $row->{ivalue};
    if ($saas_en == 1) {
        foreach my $saas (@{$Apache::Ocsinventory::CURRENT_CONTEXT{'XML_ENTRY'}->{CONTENT}->{SAAS}}){
            my $entry = $saas->{ENTRY};
            foreach my $exp (@saas_exp) {
                my $dnsExp = $exp->{DNS_EXP};
                $dnsExp =~ s/\?/\./g;
                $dnsExp =~ s/\*/\.\*/g;
                if ($entry =~ /$dnsExp/ || $dnsExp =~ /$entry/ ) {
                    $dbh->do("INSERT INTO saas (SAAS_EXP_ID, HARDWARE_ID, ENTRY, DATA, TTL) VALUES (?,?,?,?,?)", {},  $exp->{ID}, $Apache::Ocsinventory::CURRENT_CONTEXT{'DATABASE_ID'}, $entry, $saas->{DATA}, $saas->{TTL});
    return 1;


Thats out of the saas.pm file from github contributions. Since i'm not a perl expert it was only a try - and seems not to work.

Apache Error Log is empty on that topic, the access_log shows a post command for the entry when testing with one host manually. OCS NG Gui shows no hosts at all.

Any ideas?

Regards, Stefan


I removed the 2.5 server installation completely and dropped the database. Then reinstalled the RPMs for RHEL7 and the OCS Server 2.4. Then its working. Afterwards i updated the OCS NG Server to V2.5. Now the connections working and the logs are clean. Cant say what was wrong.
