root access lost

[Adam Noble]

We have a system whereby the root password has been disabled, unfortunately we do not have a system console at the location to bring it down to single user and change it. Is there anything we can do? I realise I'm basically asking how to hack the machine but is there anything we could do. Is it possible to emulate the console via a PC and cable?

Hi,

could you explain, what you mean with disabled?

thanks,

Michael

a certain individual set it so that after three failed root logins the system became disabled....you could still login via the console if we had one!

Don't know what type of system you are having D class or the N/L class.

depending on the serial port behind the server, you can have a serial cable, connect it to the PC's serial port. Have done this for a D class server using a 9 pin serial cable. Run hyperterm from the windows PC. set the baud rate to 9600, no parity data bit of 8 and 1 stop bit.

You will get everything coming on console to this PC.

yes, the same thing for any L class or N class, provided you have the correct cables. Hope you are having it as you are already connected to a console.

You could try installing X emulation software (Exceed) on one of the PC in the network and it should work.
You can have CONSOLE emulation on your PC using X emulation sofware.
