ERROR *** AGENT => Failed to send Prolog <URL using bad/illegal format or missing URL>

Question

I'm a newbie on OCS Inventory and have been helped by a friend to set up OCS Inventory on a LAMPP stack. Now that I'm installing the first Windows client I'm already getting in trouble with the communication of client and server.

Here some technical details:

SERVER system

• OS Name : Linux x86_64
• Version : 4.8.0-1-amd64
• RAM installed : 492 Mo
• Free RAM : 144 Mo
• CPU : Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz
• Distribution : Debian GNU/Linux 9 (stretch)
• PHP Version : 5.6.20-1 (apache2handler)
• Web Server : Apache/2.4.25 (Debian)
• Database Server : (Debian) version 5.6.30-1
• Version OCSReports: 2.3

Client System

• OS: Windows 7 Enterprise 64-bit SP1
• OCS Version: 2.3.0.0

OCSINVENTORY.INI

[OCS Inventory Agent]
ComProvider=ComHTTP.dll
Debug=1
Local=
NoSoftware=0
HKCU=0
NoTAG=0
IpDisc=
[HTTP]
Server=http://myserver:80/ocsinventory
SSL=0
CaBundle=cacert.pem
AuthRequired=0
User=
Pwd=
ProxyType=0
Proxy=
ProxyPort=0
ProxyAuthRequired=0
ProxyUser=
ProxyPwd=
[OCS Inventory Service]
PROLOG_FREQ=10
INVENTORY_ON_STARTUP=0
OLD_PROLOG_FREQ=10
TTO_WAIT=19740

The client is installed as service with Local System account and started. The systray app is running and I'm able to start the "OCS Inventory agent now" and also let me "Show inventory information".

A read a lot of FAQ, Q&A, WIKI, DOCS and forum but my problem seems to be a bit unique, because when I call "ocsinventory.exe /server:myserver /debug=2" I'm  missing 'http://myserver:80/ocsinventory" in the line
"COM SERVER => Sending HTTP Post request to URL <>", see full debug log below.

Does any of you have a small hint to help me.

Thanks a lot in advance

Answer 1

Hi

ocsinventory.exe /server:myserver /debug=2 is not the correct command to use by hand.

You must use ocsinventory.exe /server=http://myserver/ocsinventory /debug=2

Answer 2

Dear Frank,

many thanks for your help. Now the prolog is sent successfully but I get another error message (see partial log):

================= TRACE START ===============

================= TRACE STOP ===============
AGENT => Prolog successfully sent
SUPPORT => No support detected, Registration key : N/A
ERROR *** AGENT => Failed to write Prolog Frequency <Error code 32 = The process cannot access the file because it is being used by another process.  >
ERROR *** AGENT => Failed to write inventory on startup value <Error code 32 = The process cannot access the file because it is being used by another process.  >

What means: "No support detected, Registration key: N/A"

In ocsreports web page the machine doesn't show up.

Thanks again

Heinz

Answer 3

Hi,

What means: "No support detected, Registration key: N/A" => older message which has not been removed

Error code 32 means that there is an ocsinventory.exe process always running. Stop or kill this process in task manager and re run an inventory.

Frank

Answer 4

Hi Frank,

I guess the 'old message, not been removed' is meant to be a message which has no sense anymore since it wasn't removed from the code.

The running process running might be the service which has these files 'open'. But I guess this should be the normal case.

btw. my test-PC does still not show up in the OCEreports database. Any idea?

Kind regards

Heinz
