Re: [SLUG] Wiki suggestions?

[Amos Shapira]

I think there is an "edit source" option somewhere there, if you insist on
text syntax. Personally I find its WYSIWYG interface pretty convenient,
compared to the rare times that I find myself correct entries on Wikipedia.

Re: [SLUG] Website

[Amos Shapira]

I agree the site doesn't give a great shot of confidence in Linux as a web
server, it doesn't render any page to completion for me.

There is a link to "See the code" which points to
https://github.com/sydney-linux-user-group/slug/commits/master, where the
last commit happened over three years ago (29 May 2012), so perhaps it's
just a case of deterioration more than active change.

tcptraceroute (or traceroute -T in some versions) could possibly expose

[SLUG] CloudFormation chat before last night's SLUG talk

[Amos Shapira]

Hi,

There was someone who talked to me about not having enough info about using
AWS CloudFormation over pizza before the talk last night, but I didn't get
her name before she left.

If you see this - I can possibly provide you with some working examples I
use at my workplace if you like.

BTW - it was a very useful talk about Docker. Nothing beats hearing from
someone who's actually in the trenches. It felt like I could do with a
couple more hours like this :).

Cheers,

[Amos Shapira]

I'd call these configuration files, and in any case something you don't
want to just wipe out out right without a way to restore.

Why do you propose to remove them anyway? apt-get complains about an
internal error. Your original response is identical to
http://askubuntu.com/a/337795, which someone reported to work for them
without the rm -f.

I'd say - try the sudo dpkg --configure -a by itself first.

Back to the original question - google'ing the error comes up with threads
which indicate post-upgrade troubles. Have you gone through a major upgrade
recently?

Re: [SLUG] Getting the correct time on Raspberry-Pi

[Amos Shapira]

Which distribution is it? The method to set system timezone depends on the
answer to this question.

And BTW - what you are asking about is setting the time ZONE. Setting the
correct time is usually a matter left to NTP.

 I modified /root/.profile and added TZ='Australia/Sydney'; export TZ

 How can I get this to work?

[SLUG] Silent 3.5 SATA HDD mounts, anyone?

[Amos Shapira]

Hi,

I have a TowerRAID TRM5B (http://www.sansdigital.com/towerraid/tr5mb.html)
without the caddies, and a Western Digital Red Caviear 2TB 3.5 disk.

I'm looking into mounting the disk into the tower with some noise dampers.
As far as I can tell, I need to attach some sort of a caddy to the disk
which will allow it to slide inside the slots and pushed against the back
plane.

But so far I failed to find such caddies. I only see 2.5-3.5 converters
or 3.5-5.25 converters.

Could someone give me a pointer?

Thanks,

Re: [SLUG] Best (most efficient method) recursive dir DEL

 Hi Kyle,

 You might find it worth looking at the following invocation of find:

 find top_dir -name name_to_del -exec rm -rf {} \+ -prune

 the '+' will support expansion of arguments, thus it works exactly like

Kudos for bringing this up. I wasn't aware of the + option.

1. There is no need to quote the {}, find will pass the file names already
as separate arguments without splitting them on white space.
2. As you demo above but possibly worth to stress - the + form does NOT
take a terminating ;.

Test (my Mac home directory, which contains a few standard directory names
with spaces):

~$ gfind -maxdepth 1 -type d -exec ls -dF {} \+
./ ./Downloads/ ./Sites/
./.Trash/ ./Google Drive/ ./Snapshots/
./.config/ ./Library/ ./VirtualBox VMs/
./.ssh/ ./Movies/ ./bin/
./.vagrant.d/ ./Music/ ./git-dotfiles/
./Applications/ ./Pictures/ ./macports/
./Desktop/ ./Programs/ ./tmp/
./Documents/ ./Public/

Notice how ls is passed the right directory names for Google Drive and
VirtualBox VMs

Locate only indexes path names, not other attributes (like type, size, time

On 23 May 2014 06:11, Kyle k...@attitia.com wrote:

 Thanks to all for the responses.

 Interestingly, everyone has come back with find (followed by..) as
 the best option. Perhaps this is simply a reflection of the fact my 3
 examples all used 'find'.

 I have always thought (believed) 'find' was a less efficient process than
 'locate' and kind of hoped 'locate' (or some other cmd I don't know) might
 pop up as a solution. I understand 'locate' depends on an updated 'db', but
 I figured that indexing process was still more efficient than 'find'
 trawling the structure in realtime.

What's the context of this question? Do you really want to keep all empty

-delete will fail on non-empty directories. Use -print0 -prune | xargs
-0 rm -rf to stop find from scanning the doomed directory.

Re: [SLUG] stop processing with 'if grep exit' ?

[Amos Shapira]

If you want to grep for multiple strings in the same file, and exit if any
of them is found, it is more efficient (and I think more maintainable) to
specify them in one line:

grep -q -e test2 -e test3 file2  exit 0

The -q is --quiet - just to suppress the output if you aren't interested
in it (in this case you are only interested in the exit status, not the
output). The -e flag introduces each search term.

If the list of strings to look for is longer or variable then you can feed
it to grep from a file using -f.

See man grep for all the details.

Re: [SLUG] connectivity test loop?

[Amos Shapira]

Testing for connectivity at the beginning is futile - the connection can be
lost at any point even after getmail connected successfully and started
downloading messages.
You should look for a way to get getmail to handle the failure even in the
middle of retrieving mails.
For this - google about getmail's configuration and options. I'm not
familiar with that software.

Now about your script - the way you loop it means that you'll keep growing
an unlimited chain of sms script processes, each waiting for its only
child, look at the output of ps after letting it run for a while. Use
pstree or ps -ejH if you have a better view of the relations between
the processes.

Instead, you should either (in decreasing order of recommendation):
1. Run getmail in daemon mode.
2. Use cron to fire it once in a while (be it once a day or every minute,
it's up to you) and don't forget to use a lock file to prevent multiple
getmail instances from running concurrently.
3. Use a loop, e.g. while true; do ...; done

Re: [SLUG] Weird missing files.

 Hi all I've got a strange samba issue.

 I've a Centos 6.5 box with a 3.6 raid ext4 data drive on it, shared

 Now when I browse these folders on the console I can see the files. when I
 sftp on the command line from another box I can see these files.

 But when I browse via samba or using a gui sftp client quite a lot of these
 files are missing...

 Any ideas?

[SLUG] Monitoring web servers from Australia?

[Amos Shapira]

Hi,

I'd like to monitor uptime and accessibility of a web server hosted in
Sydney.
I use Pingdom for now, but it doesn't have probes in Australia so it might
be too sensitive to network issue I don't care so much about (for now the
website targets Australian audiences).

Is anyone aware of a good, cheap (free?) monitor a-la Pingdom with
Australia-based probes?

Thanks,

--Amos

 I've not used them, but they have Sydney probes.

[SLUG] Where to look for a PHP developer?

[Amos Shapira]

Hi,

My partner is looking to hire a PHP programmer to maintain a Symfony 1 web
site (http://symfony.com/legacy, yes I know it's not the latest, but the
web company which built it for her says that current Symfony 2 isn't ready
yet).

I was about to suggest her slug-jobs as a start but it seems to have been
gone.

Can anyone recommend forums where GOOD developers can be found for such
jobs?

Although such jobs can be done remotely, it might be beneficial to have
someone local.

Thanks,

Re: [SLUG] socket dissapears, how to t/s ?

[Amos Shapira]

In your initial message about socket disappear you were looking for
/var/spool/amavisd/clamd.sock,
that's a different path to the one we see here
/var/run/clamav/clamd.sock, perhaps you have to update the path in the
client.

Re: [SLUG] socket dissapears, how to t/s ?

I'm not an expert with this specific software but general knowledge of
CentOS would lead me to:
1. I suspect your configuration switched from using unix-domain sockets to
tcp sockets.
2. permission denied on TCP socket bind would point me to selinux issues
or perhaps weird maximum, root-only port limit (unlikely). google it.

Re: [SLUG] script to analyse syslog in realtime

[Amos Shapira]

In addition to LogStash/Kibana, perhaps you want to look at something that
just sends the events to statsd (https://github.com/etsy/statsd/) which
then aggregates them into counters and ships the results to Graphite (
http://graphite.wikidot.com/).

I have have yet to get personal experience with LogStash under fire, but
my hunch is that statsd+graphite are more lightweight for your purposes.

 That error occurs when trying to access a HTTP URL with https://. Not

 You may add multiple port forwards with PuTTY, like so:

 C:\PuTTY\PuTTY.exe -L2301:127.0.0.1:2301 
 -L3128:127.0.0.1:3128root@my_centos_box

 Don't forget to use http:// and https:// as appropriate.--

Re: [SLUG] using desktop across lan ? fan speed control

Add a similar ssh tunnel on the new port (you can have as many as you like
in parallel on the same SSH connection), and access it using explicit
https: method.

Re: [SLUG] Managing software across a cluster

[Amos Shapira]

Just get it all under puppet (puppetlabs.com).
On Aug 14, 2012 9:55 PM, Steven Tucker tux...@yahoo.com.au wrote:

 Hi all,

 I have just rolled out a Scientific Linux (Redhat clone) cluster of 20
 nodes plus controller that runs torque for batching and uses a lot of MPI.
 My problem is that I periodically get asked to include some library or
 program to help out with some ones research code, and often it is something
 that needs to be installed across all nodes.

 On my Mageia cluster I simply run urpmi parallel, issue the one command
 and it installs across all nodes. For those not familiar with urpmi
 parallel, it queries all the nodes asking what rpms are needed to install
 the given software (including all dependencies), it then downloads all the
 rpms to the machine running urpmi, it then pushes the appropriate rpms to
 each node and installs them.

 Is there anything like this for Scientific Linux (RHEL) and Yum ??
 The closest thing I have seen so far is clusterssh, but its not really the
 same as each node has to download from the repository. clusterssh is a
 general tool for parallel shells.

 I am using a Redhat clone for a number of reasons, the largest being I was
 told to and don't really have choice in the matter, so no chance of
 changing distros. Scientific Linux was easy to configure and everything
 seems to work quite well, so I am quite happy with the distro except for
 the lack of a urpmi parallel type tool.

 Any suggestions ??

 cheers

Re: [SLUG] blank desktop / window management

Have you tried pointing your mouse at the screen corners or edges? It might

 If I right click on desktop I get a few options to create new folder /

 The last option gives me a window to maintain several other system
 system settings.  I cannot close this window.

 If there is no action, the screen goes blank but comes back again with
 some movement of mouse or keyboard.  At this point is asks for a
 password to unlock the screen which works fine.

 The only refined way to logout, is by using Control - Alt - Delete
 which gives me a set eof tions to log out or shut down.  This works
 well.

 How do I resolve this?

 At one stage I thought I had an issue with the screen driver but the
 behavior described above suggests that is not the real problem.
 I suspect that the software to manage the icons etc has has been
 invoked and this must be resolved at $ prompt.

 Can any one advise
   1) How to get to $ prompt?
   2) What to do when I get there?

Re: [SLUG] kernel update reboot ? deleting older versions

Ouch.
You should have looked for the packages which contain these files (probably
earlier versions of the kernel) using rpm -qf /boot/file.name and removed
then using rpm. This would also automatically update the grub configuration.
Try doing that now.

/etc/init.d/ntpd start (from

 This is a tiny desktop computer designed to plug into the HDMI video port
 on a digital TV (or computer monitor) to turn it into a Google Android
 computer. This could be useful to have at home to complement an Android
 smart phone. While intended for entertainment, with a keyboard and mouse
 (or touch-pad) this would be sufficient for web access and might be useful
 for undertaking online courses, particularly where web based applications
 and Apps are being used for education.

 The device has WiFi, a full size USB socket and a microSD slot. It is
 powered via a miniUSB socket. One feature lacking from the Dongle is
 Bluetooth for a remote keyboard, although a TV type hand-held remote
 control is provided.

 To use the Dongle as a desktop computer, a keyboard would be needed. Kogan

Re: [SLUG] Inverting network interfaces

[Amos Shapira]

What distro is it? I RH distros you can stick the MAC address on the
interface configuration file under /etc/sysconfig/network-scripts/ifcfg-*

 G'day,

 I have a rather weird problem. We've installed a router device at one of
 our customers; it is a Via motherboard and has therefore a Via Rhine
 network interface on the motherboard (eth0) and a Realtek 8139 network
 interface on a PCI card. For some reason, the drivers for the two network
 interfaces seem to spontaneously invert, with the Realtek driver applying
 itself to the Via port (and usually working OK!) and the Rhine driver to
 the Realtek port (and sometimes not working - but sometimes working as
 well). This does not follow any outside action, although the customer has
 learned that rebooting the system (cleanly) solves any non-working
 interface issue.

 Can anyone shed any light on this?

Re: [SLUG] Need to fix broken package in Ubuntu

You can tell aptitude to reinstall a package with aptitude reinstall

 Problem:

 First solution:
 took advice (silly me) to fix it by manually installing a downloaded .deb

 # dpkg -i libpopper13 [later version]

 That failed to install because of a dependency problem.

 Now I want to revert to the repository version but aptitude won't let me.
 When I try to remove the broken version it wants to take a large number of
 dependent packages with it - including cups, gimp,  and lots of other
 important stuff

 How do I get back to the repository version?

Re: [SLUG] Solid State Disk Works Okay with Linux on Kogan Laptop

[Amos Shapira]

Back it up often, that's what id suggest from reading other's experience
with SSD's.

wrote:

 I dropped my Kogan Agora 12 Inch laptop onto a stone floor. Remarkably
 there was no damage to the case or screen (the screen was open at the time
 and the computer running). But the hard disk was not functioning
 afterwards, so I replaced the 2.5 Inch SATA disk drive with a Solid State
 Disk (SSD). This turned out to be a useful upgrade: relatively easy and
 inexpensive.

 Kogan offered me a 30GB SSD, as provided in one model of the laptop, but I
 decided on a larger 60 GB unit, costing 50% more for twice as much storage.

 Replacing the disk drive required me to un-clip the battery from the back
 of the laptop and remove one screw holding a small panel over the disk
 drive. The disk then slid out and I slid the new SSD in. The new disk was
 completely blank so I booted the computer from a USB flash drive with a
 copy of Ubuntu Linux on it and then partitioned the disk with that and
 installed Linux. This took about 20 minutes.

 After installing Linux, about 40 GB of the disk is available for data. As
 I just use the computer for taking notes, the smaller 30 GB disk would have
 been adequate (with Linux taking up about 20 GB), but the extra space may
 be handy.

 The computer seems to boot a bit quicker but otherwise is no different in
 operation. I am yet to see if the battery lasts longer with the lower power
 storage device.

Re: [SLUG] Cannot create static IP address for Ubuntu 10.4

[Amos Shapira]

My favourite way to achieve this is to assign a static DHCP lease on the
modem (I.e. set it by the MAC address) that way it's also manageable for
other kinds of devices, concentrated in one place and the dhcp server is
aware of the address being in use.

 Hi all,

 I know this comes under the 'Doh' list but...

 I have a fresh Ubuntu 10.04 install. On this particular machine I want a
 static address - I'm going to try out OpenSim (long story for later).

 This machine runs off a hub which is in turn connected to my modem/router.

 I've edited the /etc/network/interfaces file as follows:

 auto lo
 iface lo inet loopback

 auto eth0
 iface eth0 inet static
 address 192.168.0.12
 netmask 255.255.255.0
 gateway 192.168.0.1


 but no success. The machine is simply not happy (I've also lost the
 network icon from the toolbar - another story) and doesn't want to connect
 to the network.

 Should I just give up and assign an address to the machine's mac address
 via the router or is there something simple (I'm guessing so) that I'm
 missing.

 Thanks in advance.

 Patrick

 I think I'll stick with redirect, that what was used in the other sites


There is a slight overhead when doing client-side redirect since the browser
will have to do another http request when it received the initial redirect,
but that's most probably negligible and worth the trouble that the client

Re: [SLUG] Skipping/Mapping bad blocks

[Amos Shapira]

You should use ddrescue (I use the gnu ddrescue) which will skip bad blocks.

 Hi Slug,

 I'm trying to save a failing NTFS hard drive. It manages to mount and
 during copying the following error will appear in dmesg:

 Buffer I/O error on device sdc3, logical block 786433

 I don't mind corrupting some files. Can I instruct badblocks to add
 the failings blocks to the bad block register (I'm assuming that's how
 badblocks/hard drives work).

 Thus whilst copying, I will not get any block errors.

Re: [SLUG] ISP for web server in Camden (south-west Sydney)

 Hello,

 I'm new to SLUG and quite new to Linux so forgive me if this query has
been wrongly directed.

 I have my own server which runs my business' web site using CentOS / LAMP.
Everything has been fine until last week when I relocated to Camden, NSW
(south-west Sydney). My ISP has informed me that ADSL2 is not available here
and moreover, that the cost of my plan will increase substantially.

 If there are any SLUG members in south-west Sydney I would be grateful if
you could advise me as to the best options for continuing to host my site.

 Thank you and kind regards,

Re: [SLUG] perl modules ubuntu probs

[Amos Shapira]

(I assume you meant clan-cpan, right?)

Mixing CPAN and none-cpan packing is an invitation to a nightmare. Either
install EVERYTHING from cpan or nothing at all.

A quick apt-cache search BinHex shows that there is a ubuntu package for
it: libconvert-binhex-perl.

If you need a CPAN package which doesn't have a .deb then there are
relatively simple tools to create .deb.

Re: [SLUG] perl modules ubuntu probs

Not sure.
I'd lean towards removing it if possible (usually should be possible through
standard CPAN commands).
Check first where the files from the CPAN package were installed vs. the
dpkg package.

 Amos, thanks

 I've done 'apt-get install libconvert-binhex-perl' m it's OK

Re: [SLUG] Upgrading OS RAID

[Amos Shapira]

On 10 January 2011 10:42, Kyle k...@attitia.com wrote:

  My goal is to replace ALL the current 500GB disks with all new 1TB disks 
 into a new RAID 1 array and yet maintain the entire machine's installation 
 and configuration.

 I.e. If it were as simple as;

 1. as suggested by Menno - install disks separately; create new RAID 1 with 
 appropriate /boot  /
 2. Copy entire contents of old RAID1 /boot and / to new RAID
 3. remove old RAID, replace old for new.
 4. Perhaps some bios fiddling and presto new disks.

 that would be nice.

 But somewhere in there I've got to transfer the system onto the new RAID. 
 Just haven't figured out how yet. Plus any other gotchas I don't yet know 
 about.

Look at pvmove, it should be as simple as that, except maybe an
extra step to get GRUB stuff on the boot sectors of the new disks (you
want grub to be able to boot from both sides of the mirror RAID).

i.e. you'll have to do something like:
1. Configure the new disk array as a new PV, maybe set aside a boot
partition outside the PV if you don't want to depend on grub2's
ability to boot from it.
2. add the PV to the Volume Group (VG) to which the old PV belongs to.
3. pvmove old-pv new-pv
4. Make sure you can boot and work with the new raid array.
5. IMPORTANT: pvremove old-pv - otherwise the system will refuse to
use the VG after you remove the old array.

 It's slow, it's racy (ie, don't run the script without locking :-) but
 it's a traditional UNIX way of doing things.

 Think I'll avoid that on principle. Providing a minor # at all seems
 strange to me. Like Linux should do it. Why do I want or need to know
 about these MINOR #s anyway?! All I want is an lo dev; far away from
 this cold nightmare (with apologies to Frederick Loewe).

You need the minor number so the driver knows which instance of the device.

Anyway - just remember that there is a set limit on the maximum number
of loop devices which can be created. The default is usually fairly
low, probably depends on the specific distro, and can be set to a
different limit as a parameter to the module.

 I've got an idiot user who has created a file on a Linux filesystem named

 I need to rename this file, but can't for the life of me remember how

 identifier.

Insert ./ in front of it so mv doesn't see the - at the beginning
of the string and tries to interpret it as a flag.

So the command could be mv ./-.mxf newname.mxf.

[SLUG] Hosting e-mail?

[Amos Shapira]

Hello,

My wife's studio's web site is hosted with web24.com.au for a second
year in a row and we are pretty happy with it, for the price it costs
us.

One thing we mistrust them with, however, is that e-mail to her domain
seems to be flaky. Test messages that we send to it not always arrive
to the destination (nor bounce).

We forward all e-mail for that domain to a default GMail mailbox and
some specific addresses (e.g. info@, which is mentioned in the
contact form) to another mailbox.

Could someone suggest a better mail service we can rent separately
from web24 and point the MX records for that domain? We don't need
fancy features (e.g. Exchange), just something which will reliably
forward e-mail to our various gmail mailboxes.

We have already pre-paid an annual fee to web24 so we'll lose money if
we try to move now, plus it's an extra effort we can't fit into our
lives right now (expecting another baby).

Thanks,
