Type :
cd /dev
ln -s /dev/cdrom /dev/hd?
with the /dev/hd? corresponding to your CD Rom :
- if you have one Hard drive, then it should be
/dev/hdb. If you 2 hard drives, then it should be /dev/hdv, ....
- if you have a scsi CD ROM drive, it should be /dev/sda
Then, the kernel will recognize /dev/cdrom as a block device.

Well, I *am* networked. Everything works great except for lpd
(well, everything I've used so far, anyway). I'll try to run
netconfig to see what could be the problem.
My /etc/hosts looks like this. I get connected via dhcpcd
127.0.0.1
localhost lduperva
I dunno if that has anything to do with it.

Ok, I know this is bad, but I'm hoping someone can help me fix my
boo-boo. I removed the qt-1.44 package using "rpm -e qt-1.44 -nodep"
(yeah, I know, kill me... don't ask why) but needless to say I've
pretty much trashed my Mandrake X install. When I boot up I get this
error:
kdm: error in loading shared libraries: libqt.so.1: cannot open shared
object file: no such file or directory
Well, I'm assuming this is because the "rpm -e qt-1.44 -nodep" killed
the file, but I have NO idea how to fix this. I'm assuming that I have
to "rpm -i <some package>" but I don't know which one(s). Can someone
help me on this? I really don't want to have to format and redo from
ground up. :(
Thanks,

^^^^^^^
This part will not work as you might expect, because the -p option
requires the encrypted password as an argument. So you'll need to
encrypt the password first, before passing it as an argument. Can't help
you on how to do that in an easy way though, but perhaps there are some
tools on the web to do this for you.

If you're lucky the original makefile also included a "make clean" (or
make distclean) option. You can try that, if not, you'll need to remove
everything manually.

Um, just an off-the-wall guess here --if removing the qt-1.44 package from
your installation produced the results you describe, don't you think that
would be the package you'd want to reinstall using rpm? Particularly in
light of the error message flagging the absence of lib*qt*.so.1?

i searched my RedHat rpms and found:
libqt.so.1
/cdrom/RedHat/RPMS/qt1x-1.45-3.sparc.rpm
libqt.so.2
/cdrom/RedHat/RPMS/qt-2.1.0-4.beta1.sparc.rpm
to search your rpms try:
for i in /cdrom/RedHat/RPMS/*rpm; do rpm -qp --provides $i|grep libqt
&& echo $i; done

And then next time you install programs, do use --prefix=/somewhere/
when doing a ./configure. It demands a bit more work. I myself have
the following structure when compiling programs myself
All programs go into
/pack/prog-name-version
and then I have:
/coll/bin
/coll/lib
/coll/etc
...
...
which all contains links to
/pack/prog-name-version/bin
...
...
...
then you can actually have more than one version of all software, and when
trying beta software its quite handy.
If you compile all software yourself you may wish to have some sort of
tool that creates the links for you. At work we uses a small tool
called packman, which does most of the work for us (I think)
see: http://sunsite.auc.dk/pack/www/packman.html for more info about packman.
The advantage of this structure is, that users only need to add
/coll/bin to their path, and you can put /pack on a seperate
disk/partition and even when upgrading/reinstalling you have all your
software available.
In /usr/ it can often become quite messy after having installed 20+
applications which doesn't always use /usr/local for such stuff.

Since Telnet is not secure, the OS won't let you telnet or FTP as root (your
data and passwords aren't encrypted, and somebody might crack into them).
You can use a program called SSH (secure shell) that will let you remotely
login as root.

I am a Linux newbie. I need to replicate an existing UNIX server onto a new
Linux server.
The directory and file structure, and permissions that I have on the
Alpha_UX box must be replicated.
There are a couple of issues:
a) since *almost* all of the permissions are the same (drwxrwx-x), if I
build the Linux box manually, I'd like to have a 'default's permission set.
Right now, if I create a file, the permissions are drwxr-x-x, but I would
like to be able to create a file, and always have the drwxrwx-x permissions
set.
b) I log onto the Alpha_UX box as <biguser>. I'd like to be able to
replicate the environment variables for <biguser>. This is because I will
want the same env variables for <biguser> on the Linux box.
c) all necessary directory permissions will have to be given to <biguser>.
Help with any or all of these issues would be greatly appreciated ! I'm
expecting to have a good Linux users book in my hands by tomorrow !

Why not just copy all the files over with correct permissions, see `man
tar`? Or `man bash` for umask, of course.

Duplicate the setup scripts, then, or dump them to file
biguser% env > foo
and reinstate on the linux box.

You really want to install rsync and ssh, actually. At least ssh, so you
can do funky things like
# cd /; ssh crappyalpha "tar cpf /home" | tar xvfp -
or
# rsync -e ssh crappyalpha:/home/ /home/ -atvvlr
and so on.

umask 2
Throw that in whatever shell rc file you are.

Some env variables will be system-specific; not much you can do there.
If you are talking about environment variables that you define, again, put them
into your shell rc file.

Unclear. You mean ownership?
chgrp
Read the man pages for the commands I have indicated here, ie:
man umask
man chgrp

Is apache vulnerable ? ( I just ask as I was thinking of doing exactly

I've never had a problem with that. Anyway, once the partitions are
mounted, it's easy to stray outside them as they all look like part of
one file system.
I'd have though ownerships and permissions would be a better mechanism.

I don't even know what that does but maybe I'll try it when I've
installed.

OK.
And you can just rebuild it in single user mode as needed ?

I've had lots of problems - but seldom with file systems which I
usually learn to hack in some way, from INT13 if needs be.

This is an Alpha so the only other one I might want is NT. For now I'll
run NT on my other Alpha box, but MS have dropped Alpha support so Linux
is 'way to go' in the long run. I guess I'll be confining NT/2000 to
Intel boxes in the long run.

I've never had a SCSI controller go down. Quite an assortment of disks
though. Three this year already.
Important stuff is usually backed up by distributing it around the
network and shipping it to clients.
I guess in the general run of things, I'd just copy it back over the
LAN. Right now, the Alpha NT box is only being a print spooler anyway,
and even that could be better done by an Intel box with a faster
ethernet card.

This all seems so much more rational than the win32 rules of thumb !

OK. I'll think of it as an alarm system...

Depends if there's space in the box.
Depends if it's a Sunday.
I'd cheerfully compress things like print queues. It's not as if they
are performance critical !
