%SECTION0{name=NoConsoleOutput}% Linux kernel messages are not printed on the console

   Question:: I expect to see some Linux kernel messages on the console, but there aren't any.

   Answer:: This is absolutely normal when using the ELDK with root filesystem
    over NFS. The ELDK startup routines will start the syslog daemon,
    which will collect all kernel messages and write them into a logfile
    ( =/var/log/messages= ).
    <p></p>
    If you want to see the messages
    at the console, either run ="tail -f /var/log/messages &"= on the 
    console window, or stop the syslog daemon by issuing a
    ="/etc/rc.d/init.d/syslog stop"= command. Another alternative is to increase
    the =console_loglevel= of the kernel (any message with log level less than 
    =console_loglevel= will be printed to the console). With the following command
    the =console_loglevel= could be set at runtime: ="echo 8 > /proc/sys/kernel/printk"=.
    Now all messages are displayed on the console.
