| | In order for workers in a Condor pool to talk to the Condor master machine, that machine needs to have the network **port 9618** open to accept incoming connections. If you have a firewall enabled on the Condor master machine, you will need to configure your Firewall to allow Condor to listen to the port for incoming communication. To do this in Fedora, run((You may have to type in your password to gain administrative privileges. Alternatively, you can just run this as ''root''.)) <code bash>sudo system-config-firewall</code> |
| | If the firewall is enabled((If the firewall is actually enabled the "Enable" button will be greyed out and only the "Disable" button will be usable.)), click "Other Ports" on the left side of the window. On the right, click the "Add" button. Scroll down to port 9618 and add the entry with "tcp" listed as its protocol. Click "Okay". Do the same for port 9618 except add the entry with "udp" listed as its protocol. At the top of the window, click "Apply". Click "Yes" in the conformation window. Your firewall now has port 9618 open for incoming tcp/udp traffic. |

| Back in the olden days, Condor used to be able to easily do idle detection based on the device files in the ''/dev/'' folder. This is great if the system has a PS/2 keyboard and (God forbid!) a serial mouse, but now with USB keyboards and mice, doing idle detection based on these USB device files is feeble, probably since USB device files vary by the make and model of the keyboard or mouse. Fortunately, Condor is now able to latch on to the X11 window manager and poll it for activity. Condor needs to run an extra daemon to do this, known as the ''condor_kbdd'' daemon. | Back in the olden days, Condor used to be able to easily do idle detection based on the device files in the ''/dev/'' folder.

| If Condor were installed from a package manager, the ''condor_kbdd'' daemon wouldn't be included since it is considered a separate software package. No big deal. Installing Condor from its source code means that the ''condor_kbdd'' program comes with the whole bundle, which is nice. Although the ''condor_kbdd'' daemon is installed, it is not activated in Condor by default. In order to activate the daemon, simply add **''KBDD''** as an item in the ''DAEMON_LIST'' configuration variable as a comma-separated list. If the ''condor_kbdd'' daemon is correctly installed, Condor will start the daemon and latch it on to the X11 window server to allow for proper idle detection of any and all applicable input devices. ((According to the Condor User Manual, the ''condor_kbdd'' daemon must run as ''root'' in order to correctly gather input device usage statistics from X11.)) | If Condor were installed from a package manager, the ''condor_kbdd'' daemon wouldn't be included since it is considered a separate software package.
