 Subject: [SLUG] clone system to a vm?

 
 I have a Centos 4 machine, I'd like to try cloning it from a physical
 machine to a VM on another system, I've installed Centos 6 on the new
 machine, and, learning how to setup VM
 
 how would I clone existing system across LAN to VM ?


I just used the vmware converter to clone a windows 2000 physical machine onto 
a virtual box VM flawlessly. 
We needed to rescue the software running on the machine due to age, so a VM was 
the way forward.
Just had to tweak the ACPI setting in the CPU advanced config and win2k booted 
straight away.
Vmware converter is a free program that does support some linuxes. Not sure if 
you can run it from linux though.

getting an image of a hard drive is one thing, getting it to boot as a vm 
straight away, is entirely different.

 But would also want some type of software that could be used to
 administer each separate server ... effectively as a group ... from
 within a single UI. Whether that has an agent installed on each
 'client' server or how it is configured, I don't know yet.
 
 But, have to start somewhere.

You should be able to start and get pretty far with webmin/usermin/virtualmin 
and 3rd party modules.

Re: [SLUG] Job Management Apps

2012-05-09 Thread Dave Kempe
RT is capable of this with a little massaging:
http://bestpractical.com/rt/

You can use custom fields, and due date and time worked etc.
The due dates can be exported as ICS and imported into Google Calendar easily 
enough.

My company provides commercial support for RT these days if you are interested.
It does take some getting used to though - If you don't have the operational 
rigour to make it work, its a waste of time.
Which is probably true for many systems.

 Hi All
 
 I've been looking for an application for a while that can be used for
 a
 handyman service - but a handyman service with a difference.
 
 Basically the handyman receives work orders from a Strata Management
 or
 Real Estate company to contact John Smith of so and such address and
 telephone number to arrange for some repairs to be carried out.
 
 Bear in mind that there are usually multiple jobs being done
 simultaneously.
 
   * First task is to contact the person in question and arrange an
 appointment. This often takes several calls.
   * Sometimes the repairs are specified in the work order but often
   they
 are not and a first appointment is usually necessary just to
 establish the extent of the work.
   * Sometimes there is a quotation required which goes back to the
 managing company - other times it's just do and charge.
   * A second appointment is often necessary to perform the work
   although
 of the planet align the job may be done and completed during the
 first appointment.
   * Often the job involves time and materials, sometimes it's just
   labour.
   * Finally the job has to be invoiced back to the management
   company.
 Currently invoicing is done in MYOB and I'm happy to leave that
 as
 it is.
 
 Whatever we can come up with would ideally have an android client or
 at
 least sync with Google calendar for appointments and / or follow ups.
 I
 was looking at SugarCRM but I think that that is a little sledge
 hammer
 / nut for this.
 
 Any suggestions? Any Ideas? Any thought?
 
 TIA
 
 Nigel.

 You'll find that Wi-Fi is fundamentally unsuitable to that many

 whatever hardware brand you throw at the problem.

I agree with Jeremy, but if you want a cheap powerful device, the TPlink

And for $75, just buy 3 of them.

My 2c on this issue..
As the company that donates the hosting to slug (rusty) we are happy either way.
It doesn't bother me to continue hosting, or to stop hosting rusty. Frankly the 
most effort goes into rusty from slug sysadmins.

As a longtime SLUG participant, I would be happy to see the volunteer burden 
reduced, and a merger with LA seems to make sense.
The SLUG identity, mailling list and google juice has some value, that should 
be preserved (and I am happy to continue to pay in the form of donating

then edit  or create /etc/hylafax/FaxDispatch like so:

and that should cover it. oh you also need to setup faxgetty to listen for

Lots of doco on how to do that on the Hylafax site (which has much improved

 So the file created on day 2 backed up on day 3 is lost.
 Can anybody point to the boat (I've missed) or confirm my vision.

Seems correct, and the primary reason why we moved to rdiff-backup and disk 
based backup.
We get to keep effective full versions for as long as we have disk space, very 
efficiently. We have some customers have 500 days worth at least of their core 
database dumps.
They needed to restore something back to 400 or so days once, and where able to 
do it in a matter of minutes, from request to delivery of the file.
It works for us, and we have at least 10Tb of backup jobs under management 
spread over hundreds of backup jobs.

I also agree with another poster - the typical restore event is the most recent 
backup, and a subset of the job at that.

http://rdiff-backup.nongnu.org/
and
https://labs.riseup.net/code/projects/show/backupninja 
to manage it. (Well a forked version of it with a few extra features...)

 How do you backup databases with that (I'm specifically interested to
 hear about PostgresQL)? Snapshot the filesystem every day?
 
 We have a 300Gb postgres database and growing rapidly, and I'm looking
 for better ways to back it up with point in time recovery other than
 backing up the transaction logs and periodic full backups.

Filesystem snapshots for databases have an inherent warning that you need to 
flush the database to disk first of course.
backupninja has a pgdump shell frontend that we use for this and it works fine 
for most people.

I don't have a specific recommendation for your large postgres database, as I 
think what you are doing is the only option.
Interested to hear if anyone else has better suggestions.

Re: [SLUG] Virtualization - Whither goes thou?

2010-05-14 Thread Dave Kempe
Hey All,
relevant to this discussion may be an internal project I have been working on 
for sometime: Honcho.

Honcho is a storage subsystem for virtualisation environments built on RAID1 
over iSCSI. It is designed to run from stock Ubuntu linux, with no single 
points of failure.
We have shell scripts that tie it all together, and are building the next 
version in ruby with a web interface etc.

The first revision of the architecture for Honcho can be viewed here:
http://img59.imageshack.us/img59/8641/honchostoragelogic.png

I was thinking of giving a talk to SLUG about it sometime, complete with 
scripts that let you provision storage and machines in one go, migrate them 
between front end servers, and resize them if you need.

We use OpenVZ on top of Honcho, but you could use KVM just as easily. OpenVZ at 
least gives you the live migration option.

Happy to answer any questions if you are interested, and interestingly enough, 
rusty, the VE that houses slug.org.au will be on honcho shortly.

Bonnie++ is what we use. You can use IOzone if you like complex charts. hdparm 
isn't great for this sort of thing.

Also, back to the one of the other suggestions - don't use RAID5. If you only 
have 3 disks, use RAID1 and 1 hotspare. They don't make disks like they used 
to, and RAID5 and MTBF stats meant that the chance of having a failure during a 
rebuild is too high. RAID5 is dead to me. RAID10 if you have enough disks, or 
RAID1 when you don't.
and use LVM. It makes for growing/shrinking/chopping much easier. You can't 
shrink XFS. Be careful shrinking ext3.

http://hardware.slashdot.org/hardware/08/10/21/2126252.shtml
and don't backup to tape. Buy lots of harddrives, and expect to buy more of 
them.

The device '/dev/loop2' doesn't have a valid NTFS. 
Maybe you selected the wrong device? Or the whole disk instead of a

Which doesn't work. Any ideas on how to find the correct offset in bytes? 
parted only prints it in MB, which I assume is an approximation. 
Or any other tips for mounting a windows created GPT partition?

 NTFS signature is missing. 
 Failed to mount '/dev/loop2': Invalid argument 
 The device '/dev/loop2' doesn't have a valid NTFS. 
 Maybe you selected the wrong device? Or the whole disk instead of a 
 partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around? 
 
 Which doesn't work. Any ideas on how to find the correct offset in

 Or any other tips for mounting a windows created GPT partition?

[SLUG] fast hashing/checksumming tool

2009-02-24 Thread Dave Kempe

Hi,
I need to checksum recursively alot of data, and store the checksums in 
a database. I can do most via a shell script, but was wondering if 
anyone could recommend a checksumming tool that was the fastest.
I know about md5sum, sha1sum, cfv (not recursive enough). I want to be 
able to produce a checksum of many files (2.1TB worth) for verification 
against other copies of the files in various locations. I need the 
fastest available algorithm, not necessarily the most secure etc.

Any suggestions?

the closest we have is backupninja - its just a shell wrapper that saves

So you make a dump with it and then rdiff that dump directory. That 
works pretty well for us (having had to do lots of restores using it).

http://riseuplabs.org/backupninja/
Backupninja allows you to coordinate system backup by dropping a few 
simple configuration files into /etc/backup.d/. Most programs you might 
use for making backups don't have their own configuration file format. 
Backupninja provides a centralized way to configure and schedule many 
different backup utilities.


I know thats not what you were after, but this is the better way to

I would suggest backup-ninja

or just plain rdiff-backup (which backupninja uses) and a simple shell

disk to disk is the only way to go i reckon

and I would just backup the entire filesystem - its safer that way, and 
the binaries of a well setup system will generally be pretty small


restoring a mirror is just a matter of booting off any rescue cd, 
formatting the target drive rsyncing the backup back onto the drive and 
making it bootable with grub. done it heaps of times and its flexible 
enough to be really useful in disaster situations.
Or you move everything to an OpenVZ instance (lightweight 
virtualisation) and rdiff across to another machine or (replicate 
databases) then you don't even need to restore your backup, you just 
'boot' it in the case of a disaster.

2007-09-18 Thread Dave Kempe
Hi, the proper way to do it is to generate an /etc/mdadm/mdadm.conf 
config file and have udadm/udev do the right thing on boot.
I have simply create the config file as per a number of howtos and from 
the manpage:


echo 'DEVICE /dev/hd*[0-9] /dev/sd*[0-9]'  mdadm.conf
mdadm --detail --scan  mdadm.conf
  This will create a  prototype  config  file  that  describes 
currently active  arrays that are known to be made from partitions of 
IDE or SCSI drives.  This file should be reviewed before being used as 
it may  contain unwanted detail.


You can probably adapt that. Not sure which distro you are using, but on 
an ubuntu i believe that works ok. You may also need to edit 
/etc/default/mdadm and make sure AUTOSTART=true. this also changed 
depending on what version of ubuntu you are using.

The udev/mdadm/kernel interactions can bite a bit here :( upstart might help

Hi All

I am Mucking around wit setting up some Software RAID Disks. I brought 5 x
500Gb USB2 external Disks and got them really Cheap. I have a situation
where I dont need Llightening fast access to files, but I need a Lot of
Space and as Much redundancy as I can get.

So I want to add these 5 x 500Gb disks into a RAID 5 array. I used the
following command:

mdadm -v --create /dev/md1 --level=raid5 --raid-devices=5 --spare-devices=0
/dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1 /dev/sdg1

And now have a running /dev/md1. After running a mkfs -t ext3 /dev/md1 I got
a Fully formatted Data Area and Mounted it to /mnt/raid

All was well and I copied over Data and had a good old Play around. Then I
re-booted the box, I got a MD1 does not exist type of error so my forst
question is this. How do I make it Stick? How do I make the /dev/md1 still
be recognised after a Reboot?

My Next Step is to mount my /home on the RAID array, but first lets see if I
can get it up and running after a Re-boot.

There is such a cipher, but netcat will be a much much faster way to do

google 'netcat tar' for many examples.

not really resumable, so you may need to rsync it afterwards, but 
perfect for that first bulk speedy transfer

Is it possible to have a null cipher for ssh/scp?

On occasion I'm on my LAN, behind a firewall/router etc, and need to

In this environment, I simply want maximum xfer rate, and minimum CPU
use. I simply want to copy the files across, and have no desire to hide
them, and have no one that I'm aware of on my LAN who would sniff them
anyway.

So I imagine there should be a -c null option to scp. But there does
not seem to be.

So the next question, which cipher has the lowest CPU overhead? DES?

Hi Larry,

Hi all,

I have a backup server in my LAN that keeps some rsnapshot

rsnapshot works by taking incremental backups, hard linking the files

consecutive backups smaller than the first big one.)

I want to send these backups to a remote server every day or so. I
tried scp'ing it, but scp resolves the hard links, causing me
headaches and too much space to be used in my remote server. I then
tried SSHFS (sshfs.sourceforge.net), and the same thing happened. Same
applies to SHFS.

I know NFS would keep the hard links instead of resolving them (cp
-d), but I'm not up to put NFS over the internet since that can be a
bad idea from the security standpoint. So my question is: is there a
way for me to make that transfer and keep the hard links?



you could use rdiff-backup (rdiff-backup.org) which works the same sort 
of way, but gives you a few extra features. and of course works over ssh 
by default

I'm thinking SQL-Ledger for the software as it has POS, but I need a

What experience is there out there and recommended suppliers for the h/w.

Re: [SLUG] Spam

The filters on a centralised server will always be behind current SPAM
trends, as far as I can see because it's more difficult to train than
your local SPAM solutions. Yes, we should have a centralised SPAM filter
(and probably do) but without someone training it it's going to lag and
more SPAM will get through.


We use Maia Mailguard as a centralised filter that users can train. I 
spose we could whack up an instance for slug to use. It would give us 
pretty much no spam over a bit of training time. I doubt its worth the 
effort though.

Re: [SLUG] linux to linux shares

NFS

So that UID/GID security can be retained between linux boxes on the

samba can deal with permissions in a sane enough fashion.
You really think NFS is better than CIFS/smbfs?
I have been thinking about this for a while and welcome some discussion 
on the matter. I prefer samba even for linux to linux shares, with a 
nice smb browser like smb4k clients don't have to touch the command 
line. I have always been wary of the lack of security and authentication 
in NFS. Samba seems so much richer a platform for file sharing, and if 
you have a mixed network, everything talks to it fairly well. With an 
ldap backend that also authenticates Linux users to login to their 
boxes, it should be pretty seamless (it is in a few places I have tried)

Re: [SLUG] RHCE exams

Michael Fox wrote:

Anyone happen to know who in Sydney is certified to run the exams for
RHCE etc? I've never done the training, but after all these years of
using Linux I am thinking it might be wise to grab a book on the
subject and learn what the exam might ask in relation to what I might
not know and then attempt the exam and prac required to get a RHCE.

Thanks


I think Redhat Asia pacific do the RHCE exams through a Sylvan testing 
centre. Not sure about that, but Redhat are the people to contact. They 
are run once a quarter I think.

ipt_recent netfilter module can help you there.
or you could just setup port-knocking.
I recommend portknocking.org as an intro

On the grapevine I've heard rumour of virtual hosting happening among
other things. If anyone who is busting a gut on this right now could
give a quick overview, that'd be great :)


Hi,
I don't know how it broke, but we have had a long offer to rehost the 
slug box for a while now. That offer was taken up finally after maddog 
being down for a while, and as a result SLUG (website and mailling 
lists) are hosted on a Xen 3.0 VM on AMD64 on one of our boxes. The VM 
is called Rusty and has 256MB Ram allocated with 10Gb of hard drive 
space. Rusty also seems to host linuxchix and AMSsig and maybe a few others.

Anyway, the new VM lives in a shiny new server in at Equinix here:

http://www.equinix.com/prod_serv_asia/sydney/
(in fact if you look closely in the first picture, the rack is the 
second one in on the third row!) :)


Solutions First is donating the VM and bandwidth to SLUG, and would love 
for everyone to be nice and refer some hosting work our way if you 
appreciate it :) Just email me if you want details.


We will also be offereing Xen based VM hosting on our new AMD64 boxes in 
the near future, (or now if you don't mind a lead time on provisioning) 
so keep us in mind if you want to try out Xen (its much better than 
UML). Though of course we are based here in Sydney, so we can't compete 
(and don't want to) with US based hosting for bandwidth. Of course we 
kick em on service :)


As for what happend to Maddog, I this Chris Deigan can fill you in.

Thanks

I take it this is 2.6 - if its 2.4 you need to run the
