RHEL 6.2 Deletes the ~/.gnome2/keyrings/login.keyring file under the current user.
Other detailed instructions are as follows:
Wireless Internet access and set key ring under Fedora (keyring)
The key ring (keyring) records the various passwords required by the application for easy user use. To use a wireless network under Fedora, you need to use root privileges to turn on the NetworkManager and Networkmanagerdispatcher two services. But the wireless network program needs to set the password.
we first log in as the root user, after entering the no-line key (I use WEP-128 bit encryption, need to enter 26 hexadecimal characters), the system prompts for two times to support the wireless network password. The connection was successful after the input. Log off and then user login, re-enter the non-line by the key, you can connect to the network. If you are also prompted to unlock the key ring at this point (nm-appletsis locked), can be denied. This can be considered to delete ~/.gnome2/keyring/login.key, the next time it will not pop up the "Unlock key Ring" prompt.
