How to stop other processes and kernel from printing output on current virtual term
Hello All,
Background ======== I am creating a virtual appliance console for a software stack on VMware ESXi. I am using Centos 5.x as the Linux distro (Guest OS). I have created a ncurses based application that does the user authentication and present him with some basic controls to do basic system administration. This application will be setup to lunch automatically from mingetty as it is happening now. We have made the configuration to launch the application on tty1 automatically after each system restart. The Issue ======= The issue which is hindering us alot are the kernel and other processes outputs that get printed on tty1 when it is active. Well it is a normal behavior that all kernel info, warnings and error messages are goes to the current active virtual console. But this also destroy our ncurses based application UI that supposed to run all the time on the tty1. The Question ========== So my question is that can we in Linux (kernel:2.6, distro:Centos5.x) stop kernel and other processes to output their text to our terminal (i.e. tty1), and also redirect all the output to tty1 except ours to some other VC such as tty2. Kindly respond anyone. We are in deep trouble due to this issue. Thanks Kashif Ali Siddiqui Linux Developer |
