It is fixed after 4.6-release in both -stable

Re: BSD and Active Directory?

2009-12-17 Thread Mauro Rezzonico

Hello.
  First of I would like to ask for forgivness if I post this question in the
wrong list, I'm new to this...

So now to my question: I have a Microsoft 2003 Active Directory server and
an already working configuration for a Centos/redhat environment. But my
problem has occured when trying to include the BSD (openbsd 4,5 with
login_ldap installed) servers and clients in the solution. I've found a
guide (http://www.obfuscurity.com/2009/08/OpenBSD-as-an-LDAP-Client) that
speaks of this but it seems to be non-functional. So my question is how does
one via login_ldap connect to a AD and auth USER that is not in the passwd
file on the machine?

 ...

You could try a book instead,
/LDAP System Administration/
by Gerald Carter, O'Reilly
ISBN-13: 978-1-56592-491-8
It is probably on http://safari.oreilly.com

The Unix examples are generic, (i.e. not for Linux only)

And I would second the suggestion to explore Microsoft Windows Services 
for UNIX (SFU)


Another solution is to get yp to work from OpenBSD to OpenBSD, then add 
LDAP on top, then migrate to AD, right now you cannot tell if your 
problems are in YP, LDAP, KERBEROS, or Microsoft AD...

Re: Backup disk over USB good idea??

Joakim Aronius wrote:
I have an old home server which ran out of disk space 

 I added a big disk over USB which I use for
 backup (mounted on /backup).

Well don't do that!

Mount under /usr/backup, or /var/backup, or /tmp/backup or whatever!

Is this due to my ancient HW, crappy USB controller card, or is USB mounted disks just less stable? 


Even if the externally powered USB disk never fails, still there is the 
chance that the two independently power supplied boxes get out of sync, 
for instance in the event of a power cycle...
You power cycle both of them: do they come back again in time to pick 
each other?
(I have a machine with a USB disk where this NEVER happens, when the 
bootstrapping OS tries to mount the USB disk, the disk is always 
spinning up or whatever but it's not ready yet so the mount fails)

If you're doing RAID for redundancy/safety then there are some things to
consider:


No. I am considering Raid, RAID1, in this case, mainly for *UPTIME*...

I do my backups very well, thanks...

Point here is that I am not considering raid as an alternative to 
backup, but as a way to keep the system up...


Please correct me if I am wrong, but when your drive fails you have 
*TWO* problems:


1) you have to restore from your (well kept, well done, well designed 
and well verified) backups (a big *IF*, if I can say);


2) the system is down until you restore everything;

So, either you have the luxury (or the need) of a hot spare machine...
Or a raid solution can /help/ you recover more quickly... or not?

Please note that although raid and/or backups and how they are 
configured in respect to each other and how they are deployed is a 
*very* fascinating topic (and I am *very* interested in hearing 
everybody's ideas, opinions, experiences on this) actually this is an 
off topic debate... Because my original question was indeed very narrow: 
Hardware or Software?


I think we all got sucked into a very 
serious/complex/fascinating/interesting/whatever issue, that of how to 
make your system more reliable, in these difficult days of complex 
network architectures...


But this is just a can of worms... I wouldn't dare to mail such a 
question to the list...

You see:
- what if you have raid level whatever everywhere?
- what if you can implement hot spare machines?
- what if your valuable data is mainly into a RDMS?
- what if your disks are cheap and your cpus are expensive?
- what if your disks are expensive and your cpus are cheap?
- what if you are using VMs?
- what if you just use ZFS everywhere (sorry I couldn't resist)?
- what if you are on the cloud (sorry I couldn't resist)?

I appreciate your post, don't get me wrong, the problem of making a 
network infrastructure rock solid and totally reliable is probably the 
secret dream of every respectable net administrator...

But I think we must chop the problem in swallow-able pieces...
