Useless use of cat. :-) Just use -i to do an inplace edit.
The .bak after the -i tells perl to copy the file to file.bak
before making any changes. So you get a backup and an edit
in one command, now thats a good deal. :-)

Subject: Zip 100 Parallel Port Drive
I am running RedHat 6.2 on one machine and 6.0 on another. Both machines
have Zip 100 parallel port drives connected. The RH 6.2 machine has Win
98 on another partition and the RH 6.0 machine has NT 4.0 Workstation on
the other partition.
My problem is that the Zip drives work fine with Win 98, NT 4.0 and
RedHat 6.0, and I have tried swapping the drives from one machine to the
other and the result is the same. Module imm refuses to load on RedHat
6.2 ( Linux Kernel 2.2.14-5.0). I get the same error message whether I
use insmod or modprobe, i.e.:-
"imm: Version 2.03 (for Linux 2.0.0)
scsi: 0 hosts
/lib/modules/2.2.14-5.0/scsi/imm.o: init_module: Device or resource
busy"
This is all strange territory to me, but does it mean that the wrong
version of imm.o is provided with RedHat 6.2? If so, how do I obtain the
correct version?
Then maybe I have got hold of the wrong end of the stick altogether.
Any help would be very much appreciated.

But there's no law that says you MUST use an ISO9660 filesystem on a
CD! You can write any old filesystem you like, as long as you're willing
to live with the hit that you can read it only on systems that understand
that type of filesystem. For example, SCO used to distribute old Skunkware
CDROMs with one of their own filesystems burned on it.
So, you should be able to create, e.g., a EXT2 loopback filesystem, fill
it up to 650 megs total filesystem size then burn it into a CD. Having
done that you SHOULD be able to mount it (with "-r") like any other
EXT2 filesystem.
: I think it's time Linux gets the ability to use writable image files, so
I seem to remember seeing that support for UDF is coming, perhaps in the
2.4.x kernel? When using a CD-RW medium it allows you to add/erase files
in a way that seems (at least superficailly) like any other R/W
filesystem. It works on Windoze (which isn't much of a recommendation, I
know! :^), so when it becomes supported on Linux you won't really need
your writable ISO stuff.

I suspect (not having a CD writer on my Linux box, darn it!) that you
could simulate what you want without needing a new filesystem, although
it will cost you some disk space:
As my suggesiton above, make a loopback EXT2 system, put in it whatever
you want, add/delete/modify to your heart's content then when ready to
burn a CD, create an empty ISO filesystem, cp from the EXT2 loopback to
the ISO loopback and voila!
Or am I all wet? (be gentle! :^)

Are you sure that you need imm.o? There are two different kinds of
ZIP-drives (from the software's point of view), so two different
modules as well.
The other module is called ppa.o

What installation option did you use? If you used Workstation-class
installation, for Redhat 6.2, there is a note stating that it will not install
the network daemon, inetd. Network-related services such as finger,telnet,talk
and ftp will not work. If you require these services, choose a server-or
custom-class installation.

Thanks for your interest.
Yes, according to the documentation I have seen, I need to use imm. However,
I have tried to load ppa also, with the same result.

You have your Win98 on extended partition and not on primary? There is no
primary windows partition on your disk? I think this is the problem. AFAIK
windows aren't able to boot from anythink else than primary p.

I had an issue sorta similar. FTP would disconnect after some of the file
transferred.
Worked OK in all other respects. This was on RH6.1, I think, using a USR
56K internal.
It turned out to be the MTU value. This has to be reduced by some discreet step,
which
I don't recall now, but you can find that on the web. Shortly after that got
solved, cable
internet became available, so I am sketchy as to exact values, and where I set
that. But,
that fixed it, and much improved the transfer throughput, as a bonus.
CROSSPOSTING is a Bad Idea :)
