Why doesn't window created by 'xterm -C' accept messages sent to /dev/console?
The device has user ownership and r/w permission for user (set on login) and it worked in RH-9. |

As I've never tried it, I can't answer your question. What I will say is that CentOS 5 == RHEL 5 and RHEL 5 has come a very long way since RHL 9.
Perhaps your closing comment is a question for Red Hat. Alan. |

I'm presently reminding myself why I delayed upgrading for so long - it's such a pain.
According to the xterm man page, it should work, but it doesn't. I wonder where the console messages are going. |

In my case, I started at around 2100 hours and finally got to bed at about 0317 hours the next day when I upgraded from RHL 9 to CentOS. I've just executed man xterm out of curiosity. For the command line -C flag I see Quote: -C This option indicates that this window should receive console output. This is not supported on It looks like the second sentence "This is not supported on all systems." is true with the version built with the current Red Hat sources. Alan. |

So where does /dev/console go to? The bit bucked? Two interesting questions to which I don't know the answer. Would you care to investigate? Assuming you've logged in as root to a GUI, get yourself to a shell prompt. Try echo Hello console > /dev/console Then <Ctrl>-<Alt>-<Fn1>, <Ctrl>-<Alt>-<Fn2>, etc and see if you can find your greeting to the console. As a quick closing thought, perhaps man -a syslogd or man -a syslog may be of interest. Hope this helps. Alan. |

Yeah, I'd already tried checking the other ttys - nothing there. Nothing in /var/log messages either.
It's not a critical problem - it just bugs me. By the way, how do you get quotes into the box in your replies? |

Convert the braces ({ }) you see in the following to backets ([ ]) and {quote}This will be in a quotation box.{/quote} The same technique is true for bold {b}bold{/b}, italic {i}italic{/i} & underlined {u}underlined{/u} text, etc. Also there are the buttons, above and the big "quote" button below. Regards, Alan. |

I inadvertently (i.e., stupidly) shut down the nfs server for the home directory of a user logged on another machine and of course it locked up. When I <ctrl><alt><bksp>ed to get out, it went to a black screen - with the messages that had been sent to /dev/console by the user. |
