Question: after a power blackout I am having trouble with my drive. I am using the ext2 filesystem. With the help of the tomsrtbt floppy distribution and a couple of documents from the LDP, I have been able to boot in single-user mode. But when I try to execute the network script, the system sticks after echoing the following:
Disabling IPv$ packet forwarding sysctl: ip forwarding off
What can I try next?

I would advise you to boot from a rescue disk and run an e2fsck on the partitions of your damaged hard disk for an automatic check:
e2fsck -p -v /dev/<partition_to_fix>
Keep in mind that messing around with your disk, even with fsck and e2fsck, may result in loss of data, so be careful that you understand what you are about to do.

You can try booting Linux with linux single or linux init=/bin/bash if all else fails. Type this at the LILO prompt. After that, you can look at the output of rpm -Va, which should tell you which packages have modified or missing files, and you can then re-install the said packages (with rpm -U --force /location/of/package.rpm) All that said, it's probably as good a time as any to upgrade your system to the latest Red Hat version, which should also fix your problem in the process.

I would like to access a Disgo 16MB USB Flash RAM device from Mandrake Linux. Will Linux automatically mount this device? If so, how can I find it?
I believe that Mandrake uses the usbdevfs pseudo-filesystem, though I don't know where it mounts. Type mount to see. My Red Hat machine mounts it on /proc/bus/usb.

Linux supports USB storage devices if you have a recent kernel version. According to Mandrake's web site, they shipped 8.1 with kernel version 2.4.8. However, because the device drivers have evolved quite a bit in the last few months, it may be helpful to update to the latest 2.4.x version, which at the time of this writing is 2.4.18. You will need both the USB device filesystem and SCSI generic support. Then, check out the Linux USB Guide (linux-usb.sourceforge.net/USB-guide/book1.html). The “mass storage” section should be helpful.
