Operating Systems SCO Need Help With System Recovery After HD Errors
# 8  
If the .iso file that you created is less than 1.44mb, then you could try copying the file to a DOS diskette instead of a unix diskette.
Code:
dosformat a:  (or /dev/fd0135ds18 instead of a:)
doscp file.iso a:

This should give you a diskette you can read in XP.
Is the failing disk scsi or ide?
# 9  
The failing disk is IDE.

Yet another "hurdle" with copying the iso file to floppy. I have tried four different floppies in the SCO drive, using the dosformat command. Each time the screen says "Formatting..." and the light on the floppy drive is on, but then it fails with: "dosformat: Error formatting drive"

I don't know if it is all of my floppy disks, or the drive just isn't working right. Like I said, all of this hardware is at least 12 years old. I have spare hardware I can experiment with - I have server hardware that was purchased around 2008, it has a CD and floppy drive in it. I could install a new hard drive and set it up as IDE, if I could locate (or I may have) the BTLD driver(s) that would allow me to do a new install of the 5.0.6 software.

At this point, do you think my best shot would be with newer hardware, or trying to go with an installation inside a VM?

I really appreciate your help.

There are ide to sata adapters (about $25 startech.com) so you could re-install using a new sata hard drive.
The only btld required would be for the tape drive, which I assume is scsi, and that could be added after the system is running.
# 11  
I just want to make sure I understand what you're saying. Do you mean to use a new SATA drive with the IDE adapter in the current server hardware? Then reinstall 5.0.6, then restore my backup from tape? I understand this thinking, because the current system has been compromised because of the lost sectors, but I'm just hoping I don't have trouble with the tape drive or the backup files. Let me know if this is what you are suggesting, and it seems like my best option. Thanks - Rob
# 12  
Yes. Remove the old drive first. Do you know if the driver for the network card is supported directly from the install media, or if you can read it if it is on a diskette?
Even if you have trouble with the tape you are no worse off as you will actually be testing the validity of your backup procedure.

Going back to the question about limiting FTP users, I regret that I don't have a SCO server available to test, however many unix OS variation have a file /etc/ftpusers which work in the reverse to what you might expect. It is a list of accounts that are not allowed to FTP into this server. It is slightly counter intuitive (to me at least Smilie) but I wrote a simple script that I run daily to read /etc/ftpusers.allowed and re-write /etc/ftpusers. It was something like this:-
Code:
cut -f1 -d":" /etc/passwd | grep -vf /etc/ftpusers.allowed > /etc/ftupusers

Would that help? You need to be careful that the input file doesn't have blank lines (which will match every record) or short user ids that are contained within longer ones. Perhaps you should make this a two step process:-
Code:
sed 's/^/\^/ ; s/$/\$/' /etc/ftpusers.allowed > /tmp/ftpusers.allowed
cut -f1 -d":" /etc/passwd | grep -vf /tmp/ftpusers.allowed > /etc/ftupusers


I hope that this is useful on SCO. Apologies if it's not. have a look at th emanual page for ftpd or whatever offers the service for you.

Kind regards,
Robin

OK, I have my new hard drive installed with the IDE / SATA adapter. Installing from the original SCO 5.0.6 boot disk appears to work fine, I am not linking to any particular driver for the HD and it appears to be recognized. However, when I get to the part about selecting my CD device, the installation does not find the CD. I know from the BIOS that it is attached to the Secondary IDE channel as the Master. Is there some kind of problem with having it as the Secondary Master? I did not change that cable at all, so I know this is how it was configured the last time 5.0.6 was installed. Any ideas why it won't find my CD? I know the CD drive has power, because the tray opens and closes. The "working" light comes on when I insert the CD. However when the installation routine says it is checking the CD the light does not come on. I don't know what to do now. Any help is appreciated.
