Avahi Reflector filtering patch

This is about transmitting Bonjour traffic across VLANs using Avahi Daemon as a reflector with a service filter patch applied.

We have multiple VLANs configured for Wi-Fi, and wired LANs and have AirServer terminals connected to classrooms needing to be discoverable from iPads and Macbooks on the Wi-Fi network.

Originally we were just using the standard Avahi-Daemon package provided by Ubuntu, but found as more BYOD laptops and iPads connected the reflected packets became greater and some services we did not want advertised (e.g. home shared printer, music libraries, etc). For this standard config there are multiple guides already available.

To filter out services we do not want I have written a patch to the Avahi code that allows you to enter a list of services you want to be reflected and only those will appear in other VLANs.

I based my implementation on the suggestion in Extending multicast DNS across local links in Campus and Enterprise Networks and it works by filtering out received packets before they are added to the daemon’s cache. All locally published services are allowed through.

Avahi-Reflector-Filter patches. This includes the main Reflector Filter patch and a patch to add _airplay._tcp to the listed services avahi-browse shows.

Avahi-Reflector-Filter.zip

For those looking to compile in Ubuntu make sure you also apply all the Ubuntu specific patches

I also needed to modify makefile input for make install to work correctly

CAU Local VM Script

Cluster Aware Updating (CAU) introduced in Server 2012 allows you to update your Fail-Over cluster by draining all the Highly Available (HA) roles from the node, performing the updates and then restoring the roles.

While this works great for Clustered HA VMs on a Hyper-V cluster, it appears CUA completely ignores any unclustered VMs on the Nodes. We have non-HA VMs on our Hyper-V Hosts that act as nodes in a File server Fail-Over Cluster and Exchange DAG groups. When CUA runs it ignores the shutdown settings of these VMs and just powers them off, this can causes loss of data in nodes and causes the cluster to have to bring up a down resource rather than just transfer the role.

To fix this we had to create scripts that shut down all the local VMs and then start them back up. These can then be set in the PreUpdateScript and PostUpdateScript profile settings for CUA. I stored the scripts on the CSV volume in C:\ClusterStorage\Volume1\Hyper-V\CAU\. These could then be added as a local file in CAU configuration wizard.

PreUpdateScript = ShutdownLocal.ps1

# VM Delay
$CheckDelay = 30

# Local VMs
$LocalVMs = Get-VM | Where-Object { ($_.IsClustered -eq $false) -and ($_.State -ne "Off")}

Updating Moodle table comments

Recently we updated Moodle to 2.6, after doing so I compared the SQL table structure of our upgraded site database against a clean install with the same addons. I found quite a few differences in table structure (smallint to tinyint, etc) for the 3rd party addons, and most core tables were missing their table comments.

To fix this I wrote the following perl script, it takes in a SQL structure dump from PhpMyAdmin and generates a list of alter commands to apply all the table comments in that file. This can then be run against your actual Moodle DB.


#!C:\Perl\bin\perl.exe

# Designed to read in SQL structure export and generate a list of alter commands to set comments from those tables

use strict; use warnings;

my $fileName = $ARGV[0];

open F, "< $fileName" or die "Can't open $fileName : $!"; my %comments = (); my $currentTable; while (my $line = ){
if ($line =~ /CREATE TABLE `(.+)`/) {
# Set current table name
# CREATE TABLE `mdl_assign`
$currentTable = $1;
}
if ($line =~ /COMMENT='(.+)'/) {
# Store table comment
$comments{ $currentTable } = $1;
}
}
close F;

foreach my $table ( sort keys %comments ) {
print "ALTER TABLE `" . $table . "` COMMENT = '" . $comments{$table} . "';\n";
}

Moodle Assignment Editor showing HTML instead of GUI editor

Recently one of teachers noticed that some Assignments that had been copied between courses would show the assignment introduction as a plaint ext box with html markup visible.

I tracked this down to Moodle recording the wrong format for the intro. To fix all instances of this in the database I ran the following query:

UPDATE `mdl_assignment`
SET `introformat` = 1
WHERE `introformat` = 0 AND `intro` like '%<p%'

This updated the format for the 1400 or so assignments that had been copied and had this problem.

IPMI Configuration on Rocks Cluster

The following is a step by step guide on setting up IPMI management on a Rocks Cluster. It is based on several great posts on Rocks Mailing list and Rocks userguide presentation

Update: On Rocks Mailing list Philip Papadopoulos mentioned a Python Script that will automatically add IPMI interface by matching the last 2 octets to that of node: Script

1. Create the IPMI Network

rocks add network ipmi subnet=10.2.0.0 netmask=255.255.0.0 servedns=true

2. Add access on head node

The IPMI network is sharing the same vlan as data, so I will multihome the Frontend with a second IP on IPMI subnet

This adds it to Rocks config, but it appears to have no effect so I also ran it manually

rocks add host interface localhost iface=eth0:1 ip=10.2.1.1 subnet=ipmi name=ipmi-frontend

Manually:

ifcfg eth0:1 add 10.2.1.1/16

Add a script to make it start at reboot

Just copy /etc/sysconfig/network-scripts/ifcfg-eth0 to ifcfg-eth0:1 and change the device and IP address.

DEVICE=eth0:1
HWADDR=00:xx:xx:xx:xx:xx
IPADDR=10.2.1.1
NETMASK=255.255.0.0
BOOTPROTO=static
ONBOOT=yes
MTU=1500

3. Set Password for IPMI

You can set a custom password for the IPMI system or use the default of admin

rocks set attr ipmi_password "password" shadow=yes

4. Add IPMI info for each node

Updated way:
Download the latest addInterface and ScarScript.py and run the following to add matching IP for each node.
If you are running Rocks 6.0/6.1 addInterface will not work for nodes whose card is not card eth0 (e.g. instead is em1). To fix this change line 67 to

"rocks list host interface %s | grep 'private ' | awk ' {print $4}'" %
for n in {0..6}; do
./addInterface compute-0-$n ipmi ipmi ipmi-0-$n
rocks set host interface channel compute-0-$n iface=ipmi channel=1;
done

Old Way:

node=0
for n in {254..245}; do
rocks add host interface compute-0-$node iface=ipmi ip=10.2.255.$n \
module=1 subnet=ipmi name=ipmi-0-$node;
rocks set host interface channel compute-0-$node iface=ipmi channel=1;
let node=$node+1;
done

Sync it

rocks sync host network

If you have every had DRAC set to use DHCP it needs to be set to static.

rocks run host "ipmitool lan set 1 ipsrc static" collate=yes

I also wanted to set the default gateway which is not set by the generated script and it will complain about network config if not set.

rocks run host "ipmitool lan set 1 defgw ipaddr 10.2.1.1" collate=yes

5. IPMI root Password

When I tried to connect using ipmitool and set password it reported NULL account disabled. To get around this is used the root account (id=2) and set a password for this.

rocks run host "ipmitool user set password 2 <password>"

6. Run the generated script on each node

rocks run host "sh /etc/sysconfig/ipmi"

7. Testing

ipmitool -I lan -H ipmi-0-0.ipmi -U root -P <password> chassis status

Compilation notes for Rocks cluster

This post is more to assist me when upgrading software on our Rocks cluster, but may be useful to others who are compiling similar software. Our cluster only has AMD nodes so we use PGI compilers. Also the backbone is only 1Gb/s so I don’t need to enable any IB options for OpenMPI. I use Modules as a contrib module with a compute-node.xml file to add a /share/apps/modulefiles path to the local config. I have copies of my ModuleFiles synced with Git here.

Also because our head node where compilation occurs uses a AMD Barcelona CPU and the work nodes use an older model I need to add a CFLAG of -tp k8-64

PGI Compilers

PGI have some info on common compilation optimisation at PGI Compilation

  1. Download from Portland Group and save to ~/install/pgi. To download over SSH I use elinks as these can be left open in a disconnected screen session
  2. Create a new directory and tar xzvf from there as it is a messy tar
  3. Root: run ./install – 1. Single System Install
  4. install dir: /share/apps/opt/pgi
  5. add ACML, CUDA
  6. update 2011 links
  7. MPICH1, ssh
  8. License keys, /share/apps/opt/pgi/license.dat
  9. Copy an existing /share/apps/modulefiles/pgi version and update it for new version. Also update .version to new version.

OpenMPI

  1. Download latest from OpenMPI and extract in ~/install/openmpi with tar xjvf
  2. mkdir build;cd build
  3. module load pgi
  4. configure with
    env CC=pgcc FC=pgfortran F77=pgfortran CXX=pgcpp CFLAGS='-fast -tp=k8-64' FCFLAGS='-fast -tp=k8-64' FFLAGS='-fast -tp=k8-64' CXXFLAGS='-fast -tp=k8-64' \
    ../configure --prefix=/share/apps/opt/openmpi/1.4.4-pgi-11.10 --with-gnu-ld --with-sge --enable-static \
    --without-openib --disable-openib-ibcm --disable-ipv6 --disable-openib-connectx-xrc --disable-openib-rdmacm --disable-io-romio

    Compiling with Torque on Ethernet Cluster

    export MYINSTALLDIR=/share/apps/mpi/openmpi/1.6.4-pgi-13.04
    export CC=pgcc
    export CXX=pgcpp
    export F77=pgfortran
    export FC=${F77}
    export CFLAGS='-tp=bulldozer-64,barcelona-64,nehalem-64'
    export CXXFLAGS=${CFLAGS}
    export FFLAGS=${CFLAGS}
    export FCFLAGS=${FFLAGS}
     
    ../configure \
    --prefix=${MYINSTALLDIR} \
    --without-openib \
    --with-tm=/opt/torque \
    --disable-ipv6 \
    --enable-static \
    --with-gnu-ld \
    --disable-io-romio \
    2>&1 | tee configure-`date +%y%m%d-%H%M`.log
  5. make -j 8
  6. make check
  7. root: module load pgi; make install
  8. Copy an existing /share/apps/modulefiles/openmpi/ version and update it for new version. Also update .version to new version and recreate symlink.

MPICH2

These instructions are for PGI and Torque

  1. Download latest MPICH2 and extract
  2. module load pgi
  3. Configure with
    export MYINSTALLDIR=/share/apps/mpi/mpich2/3.0.3-pgi-13.04
    export CC=pgcc
    export CXX=pgcpp
    export F77=pgfortran
    export FC=pgf90
    unset F90
    export CFLAGS='-tp=bulldozer-64,barcelona-64,nehalem-64'
    export CXXFLAGS=${CFLAGS}
    export FFLAGS=${CFLAGS}
    export FCFLAGS=${FFLAGS}
    unset F90FLAGS
    ./configure --prefix=${MYINSTALLDIR}  \
    --with-pbs=/opt/torque \
    2>&1 | tee configure-`date +%y%m%d-%H%M`.log
  4. make -j 40
  5. root: module load pgi; make install; make install-examples
  6. Copy an existing /share/apps/modulefiles/mpich2/ version and update it for new version.

FFTW3

  1. Download latest stable from http://www.fftw.org/download.html
  2. module load pgi openmpi
  3. ./configure --enable-openmp --enable-mpi --prefix=/share/apps/opt/fftw/3.3.3-pgi-13.04 \
    CFLAGS="-O3 -fastsse -Mvect=sse -tp=k8-64e,bulldozer-64" F90=pgf90 CC=pgcc FC=pgfortran F77=pgfortran CXX=pgcp
    
  4. make -j 8
  5. root: make install
  6. Copy an existing /share/apps/modules/other/fftw version and update it for new version. Also update .version to new version.

OpenBLAS

This replaces GotoBLAS2 as the BLAS library as Goto is no longer maintained.

To keep source up to date I use a GIT mirror, created with git clone git://github.com/xianyi/OpenBLAS I have also modified Makefile.rule and committed it to local mirror. In Makefile.rule I also needed to set architecture as head node is slightly different to compute nodes

  1. cd ~/install/openblas/OpenBLAS
  2. git pull to update source
  3. module load pgi
  4. make
  5. root: make install PREFIX=/share/apps/opt/OpenBLAS/0.1-pgi-11.10
  6. Copy an existing /share/apps/modulefiles/openblas version and update it for new version. Also update .version to new version.

VASP

Download latest version from VASP FTP server

VASP Lib

Vasp uses a shared library that is common across multiple versions. This only needs to be compiled once, and the makefile does not need any modification. I added a -tp k8-64 to FFLAGS and a clean section but they are not required.

  1. extract vasp.5.lib for a new install and cd vasp.5.lib
  2. module load pgi
  3. make

VASP Executable

The VASP executable makefile has 2 sections for a standalone run time and an MPI runtime. In each of these sections you can build a complex versions and a gamma point only version. So if you compile them all there are 4 combinations used. I use the same make file but comment out the MPI section when compiling standalone. Alternatively you can have separate makefiles and latter use make -f filename

  1. extract vasp.5.2.12 for the current version
  2. module load pgi openmpi openblas fftw
  3. Add makefile above or customise your own
  4. In makefile correct paths for libraries and features to enable.
  5. make
  6. Copy the compiled vasp executable to destination. I use vasp and vasp.g for gamma point.

Gamma Point

  1. Use same makefile as above but add -DwNGXhalf to CPP options

Quantum Espresso

  1. Download latest version from http://www.quantum-espresso.org/download.php as well as the examples
  2. tar xzvf both the src and examples. They end up in same directory
  3. module load pgi openmpi openblas fftw3
  4. ./configure F90=pgf90 FC=pgf90 F77=pgf77 CC=pgcc MPIF90=mpif90 \
    FFLAGS="-fast -O2 -tp=k8-64e,bulldozer-64" CFLAGS="-fast -O3 -tp k8-64e,bulldozer-64" \
    FFT_LIBS="-L/share/apps/opt/fftw/3.3.3-pgi-13.04/lib -lfftw3 -lfftw3_mpi" \

    LIBDIRS="/share/apps/opt/fftw/3.3.3-pgi-13.04/lib /share/apps/opt/OpenBLAS/0.2.6-pgi-13.04/lib"
  5. make pw pp -j8
  6. make all -j8
  7. to test: cd examples, modify environment_variables (e.g. tmp dir and mpirun -np ),  ./run_all_examples, then compare example??/results to reference
  8. root: copy entire espresso-4.3.2 directory to /share/apps/opt/espresso/4.3.2/pgi-openmpi
  9. Copy an existing /share/apps/modulefiles/espresso module and update it for new version. Also update .version to new version.
  1. make -j 8
  2. root: module load pgi; make install
  3. Copy an existing /share/apps/modulefiles/openmpi/ version and update it for new version.

Acrobat X – Bulk Printing and Custom Header

Every year we need to print off hundreds of enrolment forms to verify details of new students and current students. Each of these forms is pre-filled with students details and there is a separate PDF for each student.

Previously I used Multiple PDF Printer but this no longer works with Acrobat X. Instead I created an Action Wizard that allows you to select the folder with all the PDFs and it will print them all to your default printer with the default settings.

I then added another step to the action that uses Javascript to extract the student’s name from the file name and added it as a header to each page of that file. Finally this was modified so that the name is always on the outer edge, when it is printed back to back and stapled on the left.

To create this you can follow the following directions or import the attached action.

  Print Ghost Enrolment Forms with Header (960 bytes, 2,044 hits)

Acrobat X - Edit Action

In Acrobat X:

  1. File -> Action Wizard -> Create New Action
  2. Click More Tools and then click Execute JavaScript and then click Print.
  3. Change Start with to Ask when Action is Started
  4. Click on the Options button for JavaScript and paste in the following:
var strFilename = this.documentFileName;
// A regular expression to acquire the base name of the file
// Removes everything before last underscore for Ghosted_EnrolmentForm_
var re = /.*\/|.*_|\.pdf$/ig;
// Get student name by stripping path and everything to left of underscore
var strFilename = strFilename.replace(re,"").replace(",",", ");
var pageAmount = this.numPages; // Finds the length of the PDF

for (i = 0; i 	{
	if (i % 2 == 0) {
		// Odd
		this.addWatermarkFromText({
			cText: strFilename,
			nStart: i,
			nEnd: i,
			nFontSize: 11,
			nTextAlign: app.constants.align.right,
			nHorizAlign: app.constants.align.right,
			nVertAlign: app.constants.align.top,
			nHorizValue: -28, nVertValue: -10
		});
	}	else  {
		// Even
		this.addWatermarkFromText({
			cText: strFilename,
			nStart: i,
			nEnd: i,
			nFontSize: 11,
			nTextAlign: app.constants.align.left,
			nHorizAlign: app.constants.align.left,
			nVertAlign: app.constants.align.top,
			nHorizValue: 28, nVertValue: -10
		});
	}
}
  1. Click OK. Then click Saveand type in a name for the action and a description.

    Add Folders or Files

  2. Set your default printer and printer settings to how you want your documents to print (e.g. Double sided, Stapled).
  3. File -> Action Wizard -> <Your new action>
  4. Click Next on summary screen. You may tick Don’t show again box if you wish.
  5. Click Add Files… drop down and choose Add Folders… and select the folder holding the PDFs.
  6. Click Next and it will start adding the header and printing the files.

Useful Links:

  • Base for the JavaScript header is from Steve Wareham’s block post on Adding a Dynamic Stamp to a PDF.
  • The code to extract file name is from Adobe JavaScript Reference
