Configuration and deployment
On which platforms is the FusionInventory agent available?
The agent is available on Windows, OS X, Linux, FreeBSD, OpenBSD, NetBSD, DragonFlyBSD, AIX, Solaris, HP-UX. The agent shares the same codebase on all these platforms.
Is FusionInventory agent compatible with OCS Inventory NG Server?
Yes, your server will need to be configured to accept the Fusioninventory UserAgent in the ocsinventory-server.conf
#Path for external useragents reference file #!! WARNING !! : external agents may not be supported by OCS NG Community ! #PerlSetEnv OCS_OPT_EXT_USERAGENTS_FILE_PATH /tmp/yourfile.txt
The /tmp/yourfile.txt is a list of the UserAgent that should be accepted. For example:
FusionInventory-Agent_v2.1.9-3 FusionInventory-Agent_v2.1.13-1 FusionInventory-Agent_v2.2.5-1 FusionInventory-Agent_v2.2.7-3
This step is not required with the legacy 1.x server.
Please note that FusionInventory-Agent doesn’t support OCS’s IP Discover feature, and that OCS Deployment module is now deprecated and will not be developped anymore.
If you’re looking for a software deployment solution, FusionInventory provides it’s own, which is integrated into GLPI.
How to redirect OCS agent with Apache?
You can use an alias directive to redirect traffic from /ocsinventory to FusionInventory.
Alias /ocsinventory "/var/www/html/glpi/plugins/fusioninventory/front/communication.php"
Take care to declare this directive before an
Alias / XXX or it will be ignored.
Alias /ocsinventory "/var/www/html/glpi/plugins/fusioninventory/front/communication.php" Alias / /var/www/html/glpi/ <Directory /var/www/html/glpi> Options None AllowOverride Limit Options FileInfo php_value memory_limit 256M Order Deny,Allow Allow from all </Directory>
It’s also possible to use a regular expression for that.
How can I …
How can I configure two or more servers?
In the agent configuration file, you can define several servers to communicate with. For example to communicate with three servers: FusionInventory Server for GLPI 0.80 and 0.83, and OCSInventory server:
server = http://glpi080/plugins/fusioninventory/front/plugin_fusioninventory.communication.php, http://glpi083/plugins/fusioninventory/, http://ocsinventory-ng/ocsinventory
The agent will contact each server in the order defined in the configuration file, and perform the actions requested from each of them.
How can I use a mastering software like Ghost to deploy my agent?
Yes. However, take care to not duplicate agent state directory, otherwise multiple agents will use the same identifier.
How can I inventory my virtual machines ?
As for every other machine: install an agent on it.
Running a local inventory on a host doesn’t actually perform an actual inventory of its guests, it just retrieve minimal information, such as virtual machine identifier, so as to compute the relationship between the guest and the host.
How can I inventory my printers ?
For local (USB) printers, run a local inventory on the host.
For network printers, run a network inventory from any agent able to communicate through SNMP with the printer.
How can I debug agent ssl issue ?
With FusionInventory Agent 2.3.20, you can diagnostic agent to server SSL communications by starting the agent from a command line with the following parameters:
fusioninventory-agent --logger=Stderr --debug --debug --server=https://[your-server]/plugins/fusioninventory/
You will obtain very verbose SSL library messages from which you can better understand what’s going on like wrong server certificate, missing CA certificate on agent side, …
Task X is not enabled message
Task NetInventory is not enabled Task NetDiscovery is not enabled
These messages show up in the agent log when the server do not ask for an Network Discovery or a Network Inventory.
Unable to find agent to run this job message
You will get Unable to find agent to run this job message when the server can’t find an agent to run a task in push mode:
- Ensure an agent is running as service or daemon
- The server can contact http://[agentIP]:62354 directly
- Check in http://glpi/plugins/fusioninventory/front/agent.php if the agent has Network discovery and Network inventory (SNMP) modules turned on
Bad token message
“Bad token” problems means the agent and the server are not synchronized anymore. You can resolve the situation either:
- just by running an inventory
- by using
httpd-trustparameter to allow request from the server IP.
end_request: I/O error, dev fd0, sector 0 message
This can append on Linux box with floppy driver like most of the VMware virtual machine. You can work around the problem by unloading the floppy kernel module:
The error is generated when the agent launch the following command
Duplicated computers in inventory
With the default settings, FusionInventory for GLPI use the follow criteria to identify computer:
- MAC addresses
- serial number
One of this information is probably duplicated.
Missing information when called from cron
Most of the time, cron do not define a default PATH. In this case the agent won’t
find important tools like
lspci, etc ( See old Fusioninventory forge issue 1747 ).
Just define the PATH in the crontab:
Strange agent token “12345678”
Since the agent 2.3.0, the agent doesn’t use any token anymore to authenticate server messages. Any target server is automatically trusted, as well as any other IP address given through httpd-trust configuration directive.
FusionInventory Agent WakeOnLan task fails on windows
WakeOnLan agent task requires a system library (DLL) provided by WinPcap.
Just download and install the lastest WinPcap package before being able to use WOL from a win32 agent.
