[ydl-gen] YDL - wake on ssh/eth0?

Hi,

Does YDL have the capability for a machine to wake up when the  
administrator accesses them via ssh?  More specifically, could I shut  
a machine down with /sbin/shutdown and then remotely turn it back on  
without walking into the room and pushing the power button?  I feel  
like Apple OSX implemented this feature somewhere in the networking  
preferences.

Have you tried throwing a "magic packet" at it from a
program such as 'wakeup'?  I manage a small LAN at a site
about 240 km (150 miles) away and routinely wake
workstations for routine admin tasks.  I have an (always-on)
NetBSD box on the LAN that I can ssh to from the outside
world.  That machine has 'wakeup' installed and I threw
together a shell script that I can run to wake up all of the
workstations. If I wanted to ssh into a piece of sleeping
equipment on the LAN, I would have to wake it up before
trying to connect to it with ssh.  At present none of the
machines there are PPC or have YDL installed, but I imagine
similar techniques apply.

[ydl-gen] backup solution

Does a backup solution exist for Yellow Dog that is reliable.  Please
don't mention BRU (unreliable), Atempo (not supported), Netvault (not
supported), or other non-supported backup solutions.

I've heard backula is good, but it is open source and for guaranteed
disaster recovery I just find it hard to put faith in it (the motto is
"it comes by night and sucks the vital essence from your computers",
ummm doesn't sound too safe :)  Joking aside,  anybody with good
experiences with recovering a backup when your RAID goes or something?

I'm guessing most people running YDL run their backups from a separate
dedicated box with a more common os/architecture (x86 with Linux or
Windows).

Thanks

Nick

I didn't try it yet on a ppc box, but on other unix systems (including  
Linux/Intel and Solaris), amanda is /very/ reliable, and it's free.   
Please see http://www.amanda.org/ for details.  There should be rpm's  
around, too (search  on http://rpmfind.net/ for "amanda" and arch "ppc").

Hth, Albrecht.

Re: [ydl-gen] backup solution

Hi Nick!

I believe what I have to share fits into the "or something" category.  I
didn't attempt to address your original query as you then appeared to
restrict your interest to RAID.  I thought of BRU but my own research to
their site found that they don't even support Red Hat (running as a
server), let alone YDL.  

What I came up with was a simple search using yum to determine what is
available via the two URL's my yum.conf point to.  Of course, if I added
more mirrors it is quite possible that some other options may be found
by yum.  

$ sudo yum search *backup*

yum will report a brief description as well as whether the package is
available, installed etc.

As I said, this may fit into the "or something" category.  When I
executed the above the installed packages were pax, kdeadmin, rmt, and
dump.  I'm sure your yum.conf points to several mirrors so your listing
should be more extensive.  

It is quite possible you were already aware of the above.  Well, no harm
done.

Best wishes...

Re: [ydl-gen] backup solution

rsync over ssh?
A script + crontab, maybe nothing "fancy" but it works.

What do you want for a "backup tool"?

Re: [ydl-gen] backup solution


Take a look at rsnapshot.  It's a script that uses a little-known  
feature of rsync to do disk-to-disk backups that are very economical  
of space.  After the first full backup it does the equivalent of full  
backups forever but uses no more space (or bandwidth) than a series  
of incrementals would use.

       http://www.rsnapshot.org/

In my home, I have two old Apple machines side by side.  One is my  
main server (mail, web, smba, etc) with two medium sized (100 GB)  
disks in a mirror configuration.  The other is just the same, but  
it's only purpose is to be an rsync server for rsnapshot.  I run  
rsnapshot every couple of hours to keep the backup server up-to- 
date.  It takes about 5 minutes to run.  If I was truly paranoid, I'd  
put the backup server at a friend's house, and keep hers at my house.

Enjoy!

Rick

Funny, I was going to recommend something very similar that I was
using for a while:

http://www.nongnu.org/rdiff-backup/

It seems to work fairly well, although I stopped using it, because
instead what I do is simply rsync to a backup box and use tar zcf for
full backups (once a week) and simply add --newer-mtime 'yesterday'
for daily incrementals.

Cheers,

Chris

[ydl-gen] Dual monitors -- difficult second monitor

Sort of a two or three fold question here:

1. I have an Hitachi cm751U monitor (which is a Sun
monitor in disguise?) the CM751 driver doesn't work
and I've now installed three times.

I have an ATI 9800 dual head card which works fine
pumping out the video, and the dell monitor picks up
fine, but for some reason, the Hitachi is an obstinate
beast.

Finally, now that I've successfully screwed the video
up, is there a way I can boot just into a prompt? If
there is, what do I vi to fix it (appropriate info for
that would be appreciated). 

Thanks.
