Re: power down and power off also? [ Osamu Aoki <osamu@debian.org> ]
hello all!
i have a dual boot system. it is a compaq machine.
when i select shutdown in windows, the power indicator also goes off.
when i do similarly in linux, it shuts down everything, finally says
Power Down and stays there.
is there a way in which i can make linux work in a similar way? meaning,
i select halt and just have to switch off the main switch?

enable power management in your kernel.
hiya,
i think what you really want is rsync. you can do something like
su webuser -c "rsync -avP /workingdir /livedir"
(a is for preserve time/ownership/etc, vP is for a verbose status
report)
i believe that this way rsync will preserve all attributes except for
ownership, assuming that your webuser is a non-root account. the nice
thing about rsync is that it only copies over the changed/new files,
possibly saving tons of disk activity/bandwidth.
1) LIVE has a different "owner:group" than WORKING.
i think su'ing to that user will do the trick, otherwise a chown -R.
it's also possibly that you can specify which attributes specifically
to preserve, but i'd have to do some fine manual page reading.
2) If I move/rename files or diretories, I need this updated.
rsync --delete will delete files/directories in the dest dir that don't
exist in the source dir. i recommend using EXTREME caution with this
option though. a good way to test is to add -n to the call to rsync,
which does a dry run telling everything it *would* do.
3) It only has to update once every 24 hours. <- Probably cron to do this.
i use rsync for stuff like this all the time
4) I will eventually have them on seperate computers so I can't just use
the following which is what I am currently doing:
rsync can do sync's over the net too. the format is
rsync srcdir host:destdir

hi ya michelle
- the simple way to transfer files from "working" to the "live" area...
- just copy the changes
- using cron to transfer is bad because ...
a- your change might NOT yet be done at the time that
cron runs at midnight to update
- deleting the whole web tree is bad .. sometimes you can't assume the
transfer completed ... due to bad disk, power outage, network hiccup
loose ethernet wires wiggled...
- if it is extremely important to delete files on "live" than its
easiest to use "rsyn --delete ... " to delete files on the other system
( do this/that with ssh )
further, supposedly.. your old files will not be visible
on live, since its not referenced in the new site
eg ... one could do "index.html index.html.lastmonth"
just for keepsake ...
a simple way ... ( heheheehee )
----------------
cd /var/www ; wget -r http://working.foo.com
a better way ??? ( one of dozen ways to do "a better way"
- use http://www.foo.com ( live site -- /var/www )
- use http://working.foo.com
( working area /home/www.jade including separate cgi and gif dirs)
where /home/www.jade and /var/www uses the same or
peferably different cgi-bin, icons, man, gif directories
as configured in httpd.conf for the 2 different web servers
- transfering with a simple script from "working" to "live"
#!/bin/bash
#
# - avoid using cron .. unless you can guarantee the jobs are done
# when cron transfers form working to live
#
# - i dont care about "old files" that are still zombies
# on the new updated live
#
#
cd /home/jade/public_html/
# - should also include cgi-bin, gifs, ...
#
# look at the last time things changed till today
#
find * -type f -mtime "-last-time" -print \
| tar zcvf /var/www.today.tgz -T -
#
# keeps track of what was last updated/changed
# - depending on where you start your tar from
#
# you can than also trivially check it for defacements
# w/ md5sum /var/www
#
cd /var/www ; tar zxvfp ../www.today.tgz
chown -R www-data:www-data /var/www
#
#
# create a new md5sum for hourly sanity checking
#
ls -laR --full-time /var/www/* > /var/www.md5/lst.txt
md5sum /var/www/* > /var/www.md5/today.md5
#
#
# done transfering from working to live

I am just after suggestions on the best and/or most efficient means to
mirror my website (exactly) from one location to another (currently on
same computer, but eventually multiple computers).
/var/www/ LIVE <- Actual site location
/home/jade/public_html/ WORKING <- Modifications and verification
prior to copying to /var/www
I want to "mirror" Working --> Live
A few things to keep in mind.
1) LIVE has a different "owner:group" than WORKING.
2) If I move/rename files or diretories, I need this updated.
3) It only has to update once every 24 hours. <- Probably cron to do this.
4) I will eventually have them on seperate computers so I can't just use
the following which is what I am currently doing:
ON a daily basis, I just manually copy and paste the following, as I
don't trust this in a cronjob yet as I need to do it as root right
now.
a) rm -rf /var/www/*
b) cp -vR /home/jade/public_html/* /var/www/
c) chown -cR www-data:www-data /var/www
I've searched through "dselect" and found the following, and am just
looking for recommendations, or any suggestions for something better.
The choices that look like they might work for what I want.
1) mirror - Keeps FTP archives up-to-date
2) fmirror - memory efficient ftp mirror program
3) ftpmirror - Mirroring directory hierarchy with FTP
Almost but I can see a few problems here.
1) mirrordir - duplicate a directory by making a minimal set of changes

Short answer: lilo parameter apm=on
You know, you are asking lots of question here for basic GNU/Linux things.
I think it is time for you to read some introductory book on Debian.
Yep, how about reading my "Debian Reference".
http://www.debian.org/doc/manuals/reference/
For above question, it is detailed
http://www.debian.org/doc/manuals/reference/ch-install.en.html#s-apm
Good luck using GNU/Linux :-)
