So what you are saying is you have no monitor attached to this machine?
You have another computer with monitor?
Can you connect that monitor to the other computer?
If not then maybe you can get in through the serial port. Its been a long time since I dealt with serial terminals. Don't even know if FC2 is setup that way. Look into that.
Scan the machine with nmap and see if there are any services you can connect to like ssh telnet rsh. If none are there and you have not set them up then that is out of the question.
Pull the drive out install it in the working computer and mount it. Edit the neccessay files and then put back in. That may have issues with mounts since default fedora/redhat uses labels versus defined /dev points.
Put the drive in a Externel USB Enclosure, mount it, edit it, and reinstall it.
If it was Windows it would be a piece of cake. Too many open holes.
