Many of us use 'ncat' and other Windows apps to keep track of our radios. However, on three occasions here, connections have been lost on nearly all radios, with no ncat messages showing any disruption. This occurred because Windows froze ncat because I had wrongly clicked on its window at some point.
By default, clicking inside the ncat window freezes the console window ncat uses for display, and, left unnoticed, ncat eventually holds off incoming messages, which in turn, holds off 'nc' (netcat) on the radios as they report an outage recovery, which in turn holds off the 'wlanpoke' mitigation script. At some point, the radios lose their connections. With the connection down, nc never finishes, and the script is stuck waiting for an event that will not happen. The inadvertent blocking is caused by Windows "Quick Edit Mode," which allows text selection in a 'console' window without using the system menu Edit | Mark (or ^M) to freeze the display. This is highly undesirable for an app that is intended to monitor real time events. Ncat uses a Windows console for its input and output. If you notice no messages for a while, look for a solid block cursor or selection in the ncat window. If present, the console window is freezing ncat while waiting for a mouse selection. Click in the window and press Esc to unstick ncat, let the old messages roll, then go unstick your radios. To prevent these accidents, disable Quick Edit Mode: From the ncat window, click the upper left title bar icon to open the system menu, then select Properties to open the console Properties dialog. Click on the Options tab. Under Edit Options, uncheck "Quick Edit Mode," then click Ok to close the dialog and apply the settings. You can still make a selection using the system menu. Make sure ncat is not frozen when you are done. ------------------------------------------------------------------------ POMdev's Profile: http://forums.slimdevices.com/member.php?userid=70558 View this thread: http://forums.slimdevices.com/showthread.php?t=109953 _______________________________________________ Radio mailing list Radio@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/radio
