Hello linux masters.

I am runnung linux 7.0 Kernel 2.2.16-22.
I can login via telnet and serial terminals but not directly on the console.
After the bootup is finished, the login does not come up on the console. Keys pressed echo onto the screen, including control codes for arrow keys etc. There seems to be no virtual screens to switch to either.
After booting in single user mode I am able to login on the console ok.

I am not able to upgrade this server because it has some old software that won't run on any higher version of linux.

I have no idea where to start looking for this fix.
Your advice is greatly appriceated.

Thanks
Tim
 

What parameters is passed onto the kernel at startup? Look for the 'console' one.

Cheers
 
Thankyou for your questions, i hope we can get to the bottom of this.

Where do I look to find out what parameters are passed into the kernel at startup?

Someone please help me with this problem.
I don't know what to do next :(

What's the output of 'cat /proc/cmdline'?

What happens if you type '/sbin/mingetty tty1'

Cheers
 
Code:
# cat /proc/cmdline
auto BOOT_IMAGE=Not-Windoze ro root=301 BOOT_FILE=/boot/vmlinuz-2.2.16-22
# /sbin/mingetty tty1
#
Nothing happened on the console when I typed /sbin/mingetty tty1
Still just echos the keyboard the same as before.
 
Does the /var/log/messages show any error during the reboot process?
 
/var/log/messages does not report any errors during bootup process. I can email you the messages file if you need it.
 

It seems a bit like the kernel hasn't got support for virtual consoles or something?!?

Cheers
 
what happens if you change the inittab entry to id:5:initdefault and reboot, does the xwindow come up?
 

Or simpler: just type init 5

What happens if you do 'echo "test" > /dev/tty1'?

P.S. If you go to /dev do you have subdirectories like tts, disk etc.?

Cheers
