ZFS on a SAN
Hi All,
I''m new on ZFS, so I hope this isn''t too basic a question. I have a host where I setup ZFS. The Oracle DBAs did their thing and I know have a number of ZFS datasets with their respective clones and snapshots on serverA. I want to export some of the clones to serverB. Do I need to zone serverB to see the same LUNs as serverA? Or does it have to have preexisting,

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.

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

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:

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.

Problem with shared xls file. Could it be blamed on rsync?
Hi all!
I recently had a problem with a shared excel file which was rsynced from the
file- to the backupserver. The backups of this file went wrong and I can't
figure out why. The whole rsync and dump to tapes works like charm for a few
month now.
The situation was as followed. That xls lived (and was backuped) happily for
5 days. Then the users startet to share this file among 4 or 5 people.

Problems with ! -p
Hi there,
rsync version 2.5.5 protocol version 26.
I seem to be having some trouble using rsync to ignore permissions on a
remote host when syncing back to a local host. I want it to listen to
the umask of the user running the rsync locally. Eg:
[remote host - I've touched a file made it 4750, etc, etc]
hostb $ mkdir -p /data/rsync/temp
hostb $ touch /data/rsync/temp/foo

Logging enhancement
I would like to suggest a logging enhancement that would contribute
greatly to access auditing.
Currently nothing is logged when a user connects to another server as a
different user.
The auditing trail is broken for tracing access.

A simple syslog addition (for example) to ssh.c closes that gap.

2.6.2 excluding an exported resource
I have the class below to export host entries.
However I wish to override the entry for my host to 127.0.0.1
So for all of the hosts other than foo.bar.com I would like them to
have the real IP address but for foo.bar.com I would like to just have
the loopback host entry. 2.6.2 doesn''t allow multiple tags and if I
put in another entry for localhost there is a collision.

Option to turn off listen port, e.g. client only mode
Hey,
I have this setup on my small test tinc-vpn.
HostA (runs on a server and is publicly accessible)
HostB (runs on my laptop (behind firewall) sometimes and connects to HostA)
HostC (runs on a Amazon AWS server (behind firewall) to test long uptime and connects to HostA)
This setup allows me to communicate from HostB to HostC thru HostA without any issues.
Everything works great, but I
