2way authentication for SSH?
Hi,
Does anyone know of a stable / working "2way authentication" system for
SSH, and even web authentication services?
Most of the banks in South Africa have a system that, when you want to make
a payment, they send you an SMS and you need to verify the action with a
secret code which was SMS'd to you. gmail also has this.
Does anyone know of a "universal" plugin /

Setting up XEN domU causes RAID5 to fail?
This may be a coincidence or not, but I''m building a new XEN system for
myself for work purposes.
I support several different versions of a software that cannot be installed
at the same time, so I decided I wanted to setup a XEN domU for each.
I had 5 spare 500GB drives so I put them in my system and partitioned them
so I have a RAID1 boot, a RAID5 root and a RAID5 images.
I got

Hi;
Now that it's installed, how do I start it and add a user? I can hardly
believe there is *no* documentation!

NFS client firewall config?
Hi all,
Which ports do I need to have open on an NFS client's firewall to allow it
to connect to a remote NFS servers?
When I disable iptables (using ConfigServerFirewall), it connects fine, but
as soon as I enable it, NFS gives me this error:
root at saturn:[~]$ mount master1.mydomain.co.za:/saturn /bck

hot spare not so hot ??
I have configured a test system with a mirrored rpool and one hot spare. I
powered the systems off, pulled one of the disks from rpool to simulate a
hardware failure.
The hot spare is not activating automatically. Is there something more i
should have done to make this work ?

state: DEGRADED
status: One or more devices could not be opened. Sufficient replicas exist

DR hot/warm spare node patterns / anti-patterns?
With our without puppet. We are looking at setting up DR nodes with
some draft ideas. We use puppet against a git repository (with ppg)
instead of against a puppet server. Nodes are actually VMs.
Configuration ideas:
- a filesystem-level flag that indicates that the node is running as
standby spare, to use as conditional in bash/python scripts as well as
in puppet
- some services

RAID Hot Spare
I've googled this question without a great deal of information.
Monday I'm rebuilding a Linux server at work. Instead of purchasing 3
drives for this system I purchased 4 with intent to create a hot spare.
Here is my usual setup which I'll do again but with a hot spare for each
partion.
Create /dev/md0 mount point /boot RAID1 3 drives with 1 hot spare
Create two more raid setups

hot spare remains in use
Hi,
I had a hot spare used to replace a failed drive, but then the drive appears to be fine anyway.
After clearing the error it shows that the drive was resilvered, but keeps the spare in use.

ZFS Hot Spare Behavior

preferred XEN dom0 OS
Hi,
What is the preferred OS to use with XEN, as the dom0 host?
We primarely us CentOS (currently 5.6) but it seems that the native
XEN that comes with CentOS is a bit behind.
What is the preferred OS to run on the dom0''s?

using a Laptop as a KVM console?
Hi all,
Has anyone seen something like this before:
I want to use a laptop as a KVM console. Basically when a technician
goes to one of our datacentres, or clients he has to look for a free
LCD, keyboard & mouse to connect to a server (no network access,
reinstall, troubleshoot failed kernel / HDD, etc). And then hopefully
there's an open power socker in that cabinet.

how do I find out which nameserver returns a DNS query?
Hi all
If I do a "dig mydomain.co.za" from a Linux server, how do I know which
DNS nameserver returns the queries?
I seem to have a faulty DNS server, but can't see which one, so I want
to find out which nameserver (if there's 4 - ns1.myserver, ns2.myserver,
ns3.myserver & ns4.myserver) returns the queries?

Re: unable to access Linux HVM via xm console - Couldnot read tty from store: No such file or directory
HVM = fully virtualized. The question is, why are you using fully virtualized domUs? Why not paravirtualized (PV)?

no hot spare activation?
While testing a zpool with a different storage adapter using my "blkdev"
device, I did a test which made a disk unavailable -- all attempts to
read from it report EIO.
I expected my configuration (which is a 3 disk test, with 2 disks in a
RAIDZ and a hot spare) to work where the hot spare would automatically
be activated. But I''m finding that ZFS does not behave this way

CentOS 6 domU on Debian 6 dom0 not working
Hi all,
Has anyone managed to get CentOS 6 domU (i.e. guest) working on a Debian 6 do0?
Both OS''s are 32bit and I''m running XEN 4.0.1 with HVM support.
A CentOS 5.6 domU works fine on this very same server though.
When I start CentOS 6, I get the following error:
