    % ocsinventory-agent --server localhost
    # send an inventory to the OCS server

    % ocsinventory-agent --server http://localhost/ocsinventory2
    # send an inventory over http to a server with a non standard
    # virtual directory

    % ocsinventory-agent --server https://localhost/ocsinventory
    # send an inventory over https to the OCS server

    % ocsinventory-agent --local /tmp
    # write an inventory in the /tmp directory

    % ocsinventory-agent --server localhost --user=toto --password=pw --realm="Restricted Area"
    # send a report to a server protected by a basic authentication
    % ocsinventory-agent --lazy
    # send an inventory only if the a random delay between 0 and PROLOG_FREQ had been run over.

    % ocsinventory-agent --delaytime 60 -d
    # If NO PROLOG_FREQ has been preset, pick a time between execution and --delaytime for the agent to contact the server [default is 3600 seconds]


ocsinventory-agent creates inventory and send or write them. This agent is the successor of the former linux_agent which was released with OCS 1.01 and prior. It also replaces the Solaris/AIX/BSD unofficial agents. The detailed list of supported Operating System is available in the Wiki.










Most of the options are available in a short form and a long form.  For example, the two lines below are all equivalent:

    % ocsinventory-agent -s localhost
    % ocsinventory-agent --server localhost

Time before OCS kills modules processing which don't end before the timeout.


Indicate the place where the agent should store its files.

-d,  --daemon

Launch ocsinventory-agent in background. Proc::Daemon is needed.


Turn the debug mode on.


This option is designed for backend module developer. With it enabled, ocsinventry-agent won't try to load the Backend module installed on the system. Instead it will scan the ./lib directory.


This option defaults to waiting a random() time between 0 and 3600 before initially contacting the server assuming NO PROLOG_FREQ has been set. Once PROLOG_FREQ has been set, it uses that number at the top end of it's random setting. Useful for pre-setting a deployed agent's initial start time (so you don't jam the server all at once, but don't have to wait an hour to make sure the deployment worked).

-f,  --force

The agent will first contact the server during the PROLOG period. If the server doesn't know the machine or has outdated information, it will ask for an inventory. With this option, the agent doesn't run the PROLOG with the server first but directly sends an inventory.

-i,  --info

Turn the verbose mode on. The flag is ignored if --debug is enable.


Do not contact the server more than one time during the PROLOG_FREQ and do an exit if there is nothing to do. Useful if you want to start the agent script regulary from the crontab but don't want to overload the server.

-l,  --local=DIR

Write an inventory in the DIR directory. A new file will be created if needed.


Log message in FILE and turn off STDERR

-p,  --password=PASSWORD

Use PASSWORD for an HTTP identification with the server.

-P,  --proxy=PROXY

Use PROXY to specify a proxy HTTP server. By default, the agent uses HTTP_PROXY environment variable.

-r,  --realm=REALM

Use REALM for an HTTP identification with the server. For example, the value can be 'Restricted Area'. You can find it in the login popup of your Internet browser.

-s,  --server=URI

The uri of the server. If URI doesn't start with http:// or https://, the assume the parameter is a hostname and rewrite it like that:

    % http://servername/ocsinventory

If you want to use https or another virtual directory you need to enter the full path.

--server is ignored if --local is in use.


Print the inventory on stdout.

    % ocsinventory-agent --stdout > /tmp/report.xml
    # prepare an inventory and write it in the /tmp/report.xml file.
    # A file will be created.

Authorized OCS to scan home directories to increase the Virtual Machine inventory. WARNING: beware with user privacy by using this option because it may encounter private data scans (even if it's not designed for !).


Check SSL communications using a certificate. Set to 0 if you want to disable certificate check or 1 to enable (needs CA certificates file path in this case) . Default is set to 1.


Path to CA certificates file in PEM format, for server SSL certificate validation. Set to <your server configuration directory>/cacert.pem by default.


Mark the machine with the TAG tag. Once the initial inventory is accepted by the server this value is ignored and you've to change the information directly on the server. The server do so in order to centralize the administration of the machine.

-u USER, --user=USER

Use USER for the server authentication.


Print the version and exit.


Wait before initializing the connexion with the server. If DURATION equal server the agent will use the PROLOG_FREQ of the server to determine the duration of this periode. Exactly like it would had done if it was in --daemon mode. Else if duration is a numerical value, it will be used directly.

    % ocsinventory-agent --wait 5 --server localhost

Do not inventory the software installed on the machine. --nosoft also works but is deperecated.


Deactivate local mode even if it is set in config file or command line

Config File

The agent try to initialize the settings from the ocsinventory-agent.cfg config file.

It looks for the file in these directories:
