Thanks. That works on the 3rd machine, but not on the fourth...
1044:nimitz(** ROOT **):/lib/modules/2.2.15# ifconfig eth0:1
192.168.1.127
SIOCSIFADDR: No such device
SIOCSIFFLAGS: No such device
It definately has a twinked kernel. I shall have to dive into that
I suppose and try and figure out that they did. It does not have
a module file for ipaliasing.

Samba should be using password encryption to work with any win OS from
winnt4.0 SP3. This includes win98, and any subsequent issues from
Microsoft.
Are the windows clients configured to send clear text passwords ?
Last time I checked, My win2000 pro computer connected through SMB to my
linux computer ( But I am running RH 6.0 on the latter ).
I prefered to change Samba to use encrypted passwords as that was much
easier than running around with a registry fix for windows and rebooting
each computer.
Unless RH7.0 is really buggered, things should be working fine once setup
as per the instructions.

You need to authenticate before you are able to see the shares.
Use encrypted passwords.
Tell samba to use the domain controller for authentication
encrypt passwords = yes
Security = share
Password server = <ip of domain server>
Oh, and create unix accounts for the users.
Then, what's shared out will be their home dirs.
Additionally , you can put an entry in the common part to share out the
cdrom drive or some other read only partition.
I use this at home to share out my mp3 files.

There are cases where sendmail configuration falls down, though. I had
serious troubles setting up masquerading adequately for one particular
configuration, for instance -- no matter what I did, the hostname (as
returned by the "hostname" command) crept into the messages, which in
this particular case was NOT desirable. Perhaps there's some easy way to
get around this in sendmail.cf, but if so I couldn't find it. (I'm
admittedly far from an expert on sendmail.) This was comparatively easy
to fix in both qmail and Postfix.

As always, it depends on one's needs and experience. Somebody with
years of experience futzing with sendmail will doubtless have no
trouble with it. Likewise for somebody whose desired configuration is
pretty close to what sendmail does by default. Some people aren't so
lucky, though, and in at least some of these cases, it is easier to
ditch sendmail and replace it with something else. Whether that
"something else" should be qmail, Postfix, Exim, or some other program
is a matter to be decided on a case-by-case basis. (I tried all three,
and ultimately settled on Postfix, but that's just me. Also, my needs
have since changed, so I don't know if I'd make the same decision were
I to do it again, but I'm still using Postfix out of inertia and
because it meets my changed needs as well as it did my needs when I
first switched to it.)

This doesn't reflect my experience when I was trying to get the systems
up and running. qmail was frustrating in some ways, but sendmail was far
worse for my particular situation at the time.

Minor point of clarification: The default main Postfix configuration
file is /etc/postfix/main.cf. There are several others in the same
directory, but on my system anyhow, I don't see anything called
postfix.conf.

Running a file transfer utility just to rename a few files seems to be
a mite of overkill.
Not that the alternatives don't have some aspects of complexity...
:-(
Supposing all the files are of uniform length, e.g.
file1.abc
file2.abc
file3.abc
...
file9.abc
I would do [I'm using zsh here; csh works similarly]:
% foreach i (file?.abc)
> short=`echo $i | cut -b 1-5`
> mv $i "$short.123"
> end
Alternatively, if the list would include "file9.abc" and "file10.abc",
I'd use:
% foreach i (file*.abc)
> short=`echo $i | cut -f 1 -d .`
> mv $i "$short.123"
> end
In Korn shell or Bash, you might instead do:
$ for i in `ls *.abc`; do
short=`echo $i | cut -f 1 -d .`
mv $i "$short.123"
done
These solutions are somewhat preferable to using Kermit insofar as
anyone with a functioning Linux system is likely to have at _least_
Bash installed, and doubtless has "cut" and "mv" around as well.

Remember that du is concerned with disk usage. The minimum disk space
used by a nonempty file is the fragment size of the filesystem, which
may be 512 bytes, 1024 bytes, 4096 bytes, or some other value. John's
filesystem seems to have 1K fragments.
Adding up the sizes reported by ls -l for files will underreport the
space on the disk used by those files. If you are interested in
disk usage, use du. (It also knows not to count multiple links to the
same file more than once.)

I assume the ramdisk support is compiled directly into the kernel, so
you'd have to use the ramdisk_size kernel parameter to start up with a
ramdisk of 32M. You can pass that via LILO with an append= statement,
or use rdev to change the value directly in the kernel. One caveat: It
seems as if there's no support for having 2 ramdisks of unequal sizes!
This may pose a problem, if the initial ramdisk and the auxilliary
RAMdisk you're loading are both sized as 32M and the machine only has
32M, you could run out of memory and lose severely. Argh, can't easily
test this out atm; the only time I use ramdisks is for rescue or install
purposes....

The rule is that when you start X, it _should_ set up ~/.Xauthority;
this might get generated either by 'startx' or by 'xdm', depending on
how your system starts X.
It should be quite a safe thing to nuke the .Xauthority file on the
new machine; it may be that the permissions are inappropriate and that
'startx' is getting confused.
