ssl certificate problem
I''ve tried to implement puppetmaster High Availability (mon+heartbeat).
Herefore, the puppet client and puppet master are running on both servers.
When the puppet client starts up, it generates a certificate, public and
private key for the machine it runs on.
When the puppet master starts up, it changes something so that the puppet
client have no valid certificate anymore (the

ZFS and Virtualization
Hi experts,
I have few issues about ZFS and virtualization:
[b]Virtualization and performance[/b]
When filesystem traffic occurs on a zpool containing only spindles dedicated to this zpool i/o can be distributed evenly. When the zpool is located on a lun sliced from a raid group shared by multiple systems the capability of doing i/o from this zpool will be limited. Avoiding or limiting i/o to

Does ZFS work with SAN-attached devices?
Hi All,
Its been a while since I touched zfs. Is the below still the case with zfs and hardware raid array? Do we still need to provide two luns from the hardware raid then zfs mirror those two luns?

Thanks,

Hi,
How difficult would it be to write some code to change the GUID of a pool?

Faulted Pool Question
I just got a call from another of our admins, as I am the resident ZFS
expert, and they have opened a support case with Oracle, but I figured
I''d ask here as well, as this forum often provides better, faster
answers :-)
We have a server (M4000) with 6 FC attached SE-3511 disk arrays
(some behind a 6920 DSP engine). There are many LUNs, all about 500 GB
and mirrored via ZFS. The LUNs

Good evening
I use d as follows.
(It is every 5 minutes from Cron)

ssh port forwarding
Hello Everyone,
I am having a problem with setting up port forwarding from one of our local
CentOS machines to an AWS EC2 instance. We are wanting to make mysql
connections over an ssh tunnel.
In this case, lets say that hostA is our local machine, and hostB is the
Amazon EC2 instance. I have tried several different variations (that I have
found from google searching), including:

Help on a Nat To Nat soluction - tinc servers won't ping remote clients
I have a three tinc server setup, similar to "4.3 How Connections Work" using the configuration mostly likehttp://ostolc.org/site-to-site-vpn-with-tinc.html
The clients (Ubuntus, Debians and Windows 10s) can all ping (and SSH) to each other remotely.
As far as that is concerned it's working great - thanks so much for some great software.

Rule of Thumb for zfs server sizing with (192) 500 GB SATA disks?
I''m trying to get maybe 200 MB/sec over NFS for large movie files (need large capacity to hold all of them). Are there any rules of thumb on how much RAM is needed to handle this (probably RAIDZ for all the disks) with zfs, and how large a server should be used? The throughput required is not so large, so I am thinking an X4100 M2 or X4150 should be plenty.

sftp over 2 hosts?
Hi list,
I tried sftp and it works perfect via a direct connection between 2 hosts. Our situation is that we have to go from our intranet through a firewall gateway to the internet and then to a third server. With "normal" ssh this works via: "ssh -t hosta ssh hostb". It seems to me that this doesn't work with sftp ;-((. Would it be complicate to implement?
Thanks

tinc as layer 2 switch doesn't automatically mesh with other nodes
We have a handful of nodes set up. Some are NAT'd but a few have direct
access to the Internet.
Sample confs:
HostA:
Name = HostA
AddressFamily = any
Interface = tap0
Mode = switch
Connectto = HostB
GraphDumpFile = /tmp/mesh
HostB:
Name = HostB
AddressFamily = any
Interface = tap0
Mode = switch
Connectto = HostA
GraphDumpFile = /tmp/mesh
And so on. If I use HostA as the main meta sever.

multi sync (>2 servers) + selective sync + trigger
Hi all,
I've been researching ways to replicate mail across multiple mailstores and have a few questions.
Synching 2 mailstores (M1 & M2) via dsync works fine.
I want to add a 3rd and 4th (M3 & M4) server to also be synced.
Multi-sync (>2 servers):
1) How do I tell M1 and/or M2 to also sync to M3 and/or M4?
Selective sync:

Rsyncing without RSH or SSH ?
People,
This doesn't seem possible - would it be possible to hack a version of
rsync to do it?
As an exercise, I want to create a VM image (or at least backup of all
the files with rsync) from a SCSI drive in an old Red Hat (NOT
Enterprise) v5.2 Linux 486 machine (circa 1999 that does have rsync on
it but it has protocol problems talking my server). The 486 has:
