Who knows? But since tar has been used for doing backups for
about 30 years, your Subject is highly misleading and I suspect
you are a troll. If not, post the command you used to create the
tar file.

When cron runs, it emails a copy of any output to the owner of the cron
job. This is filling my hard drive with useless drivel. I have
commented out the "MAILTO=root" line in the crontab file, with no
apparent success. I cannot find the source code for the cron daemon to
edit it directly. Anyone have any ideas?????

Were any of these files symbolic links to other directories (outside of
the scope of the tar backup)? By *default* tar backs up the link, but
not the file the link points to. Add the '-h' option to make tar
'chase' symlinks.
*I've* never had problems with tar backups.
Also, *exactly* what did you give tar as arguments? Note that:
tar czvf /backups/me.tar.gz -C ~/ .
is *different* from
tar czvf /backups/me.tar.gz -C ~/ *
The former collects all of the files in your home directory, including
the 'hidden' files and directories. The second only backs up the
non-hidden files and directories.
Also, the tar file will be different if you use a command like
tar czvf /backups/me.tar.gz -C ~/ .
vs.
tar czvf /backups/me.tar.gz ~/
although the actual contents will be effectively the same. I'll leave
it as an exercise to figure out just what is different -- should be
obvious after a couple of minutes thought.

All you need is rsync. It will do *everything* you want to do with a

can fetch it from under <http://rsync.samba.org/rsync/>. It comes with

It's not so much a question of greed; merely fairness. I've been in
the position before where I got hired on at a wage, then discovered
a few months down the road that someone that does an inferior job
(by my estimation and management's appraisals) was hired on at - and
was continuing to make - significantly more than what I was making.
So no, not greed exactly. I just don't want to repeat that sort of
rude slap in the face through naivety.

Doing some quick math, that works out to around $14.50/hr assuming
$30,000 gross annual income, 40 hours a week. I was thinking low- to
mid-thirties, but if sysadmins are routinely making $45k+ I'd feel
like I low-balled myself (doing the same work for less pay). Hence
my inquiry.

Why?
I probably should have been more clear.
I'm *not* looking to gouge my future employer. I *am* looking
to avoid selling myself short. I simply don't want to be in a
position in a few months or a year where I realize that others,
doing the same job, are being better compensated. (Had that
happen. Really sours one on the experience.) The whole "same
work, less pay" thing.
I'm not looking for more than I'm worth, just trying to get a
feel for what I am worth. Does that make any sense?

I have a RAID-1 using two HD (/dev/hdb1 and /dev/hdc1).
I think I have some problem with the second HD, so I`ll change it. The
problem is that I don't know how re-activate it (which raid-command must
I use to copy hdb1 to hdc1 without use restore/backup).
Someone knows were can I find more information about this?
thanks.

We've been using tar for years, and I've been able to restore
whole file systems on several occasions. I've also recovered
individual files. Either you are doing something wrong or
there is something seriously wrong with your system. You should
give us details including what OS and release you are using,
which version of tar, what you are using for a backup device,
and what command you were using.

The usual reason for this is that there is a new way to handle
the parallel port. You probably need
alias parport_lowlevel parport_pc
in /etc/conf.modules. There is a discussion of this point somewhere
on the RedHat website.

MAILTO=root is superfluous, as it is the default.
Put in a line that says: MAILTO=""
That'll fix it.

Underpaid? That's interesting because whenever I've talked to people

I'm currently an A/P earning over US$100K. 35hr a week but admittedly,
no benefits.

OK fairness, but if you're happy with what you get, does it matter if
everyone is getting more than you. It only does when you find out.
That's a problem. I was quite happy earning my hourly rate, even
finding that some, doing the same job for the same length of time were
on more. It's all what you can bid for. They bid higher and got it.
Some even GP�10/hr more!
Good on 'em I say.

Subject: Linux print spool setup - Help
Date: Mon, 06 Mar 2000 10:58:55 +1100
Linux uses BSD print spool model. Is there an option available to
use/install System V print spool on Linux?
The reason I need to use System V print spooling is that it allows
customisation of printer interface script to a point that you do not
have to 'print' something and you can use a print queue to serialize
access to a resource and that resource does not necessarily have to be a
printer device. Whereas BSD print spool mechanism does not allow this
flexibility. In BSD, you can use your own filter scripts but lpd will
make sure that it cats to a printer device.
Can please someone let me know if I can configure Syetm V print spool
mechanism on my linux box and how?
Please email me asap.
Thanks in advance
