# Disable host name verification

Turn off host name verification in one of the following ways:

- On the command line of an SSL client, enter the following argument: `-Dweblogic.security.SSL.ignoreHostnameVerification=true`

  Note: When using stand alone SSL clients, host name verification must be set on the command line or via the API.

- In the WebLogic Server Administration Console:

1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
2. In the left pane of the Console, expand Environment and select Servers.
3. Click the name of the server for which you want to disable host name verification.
4. Select Configuration > SSL , and click Advanced at the bottom of the page.
5. Set the Hostname Verification field to None.

   BEA recommends leaving host name verification on in production environments.

6. Click Save.
7. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
   Not all changes take effect immediately—some require a restart (see Use the Change Center).

After you finish

All the server SSL attributes are dynamic; when modified via the Console, they cause the corresponding SSL server or channel SSL server to restart and use the new settings for new connections. Old connections will continue to run with the old configuration. To ensure that all the SSL connections exist according to the specified configuration, you must reboot WebLogic Server.
