Publish the Daily Garfield on Facebook shell script

Posted on by

For years now, I’m posting the daily Garfield and Dilbert comic on my Facebook page.

This is the (clumsy) script that does that:

#!/bin/sh
URLBASE="http://comics.kamens.brookline.ma.us/cgi-bin/comics?which=specified&Garfield=include&specified=Garfield&numdays=1&width=&height=&noheaders=on&reload=reload"
wget -O page.html -erobots=off ${URLBASE}/
IMGURL=`grep "assets.amuniversal.com" page.html | awk -F'"' '{print $8}' | head -1`
wget -O garfield.gif ${IMGURL}
./mail.pl garfield.gif your-mobile-FB-emailaddress "Daily Garfield"
rm -rf page.html && rm -rf garfield.gif

Since I don’t want to use Mutt or sendmail, I’m using perl and Mail::Sender:

Mail.pl:

#!/usr/bin/perl -w
# Usage: ./mail.pl attachment to-address subject
my $file = $ARGV[0];
my $tolist = $ARGV[1];
my $subject = $ARGV[2];
my $datum= `date "+%d-%m-%Y"`; # optional
use Mail::Sender;
$sender = new Mail::Sender;if ($sender->MailFile({ 
smtp => 'localhost', 
from => 'fromuser@domain.com', 
to => "$tolist", 
subject => "$subject - $datum", 
msg => " ", 
file => "$file", 
}) < 0) { 
die "$Mail::Sender::Error\n"; 
} 
print "Mail sent OK.\n";

As always, YMMV.

CouchPotato and beta.nzbs.org fix!

Posted on by
4

Crap, for some weeks I wasn’t able to get CouchPotato use Nzbs.org for searching the NZB’s in the queue. Seems that CouchPotato can’t use the new beta version of nzbs.org and/or can communicate using the new api.

NOTE: this is a fix fot the ORIGINAL version of CouchPotato, not the new V2 / CouchPotatoServer.

To fix this, replace 3 files in your (Linux) CouchPotato installation folder; in this example I’m using my folder structure:

nzbs.py in /opt/couchpotato/app/lib/provider/yarr/sources/
base.py in /opt/couchpotato/app/lib/provider/yarr/
rss.py in /opt/couchpotato/app/lib/provider/

Now, fill in your beta access info (you can find that using the RSS page: http://beta.nzbs.org/rss) into the Provider page of CouchPotato.
The ID and code are NOT the same as the ones you can find in the ‘classic’ pages!

For example: &i=4672&r=2d42343723487fea49a3aa4745b80ae810

Save and restart CouchPotato! All should be ok now!

ClamAV as a service on Windows with Kerio Connect / Mailserver

Posted on by

Do you know how hard it is to install ClamAV as a service, together with Kerio Connect / Mailserver ? I do. Very annoying but since you don’t want to pay for the extra AV option within Kerio Connect / Mailserver, ClamAV could be a nice option. But how. Well, it’s a mix of a bundle of tools. Let me get you started. NOTE: this is NOT the perfect way to install, but it worked for me so YMMV.

1. Install ClamWin Free Antivirus (this doesn’t install the service but it’s an easy way to get the database updates…). Use this path when installing: C:\ClamAV.

2. Download ClamAV for Windows and extract it to C:\ClamAV

3. Create these extra folders:

C:\ClamAV\tmp
C:\ClamAV\db

4. Modify the Antivirus Database download folder in ClamWin Free Antivirus to point it to C:\ClamAV\db and update the DB.

 

 

 

 

 

 

 

5. Paste the Kerio Connect / Mailserver ClamAV config to C:\ClamAV\clamd.conf

PidFile C:\ClamAV\clamd.pid
LogFile C:\ClamAV\clamd.log
DatabaseDirectory C:\ClamAV\db
TemporaryDirectory C:\ClamAV\tmp
TCPSocket 3310
TCPAddr 127.0.0.1
DetectPUA yes
DetectBrokenExecutables yes
HeuristicScanPrecedence yes
ArchiveBlockEncrypted yes
StreamMaxLength 30M

6. Now for the tricky part: running clamd.exe as a service (clamd.exe –install didn’t work for me). You’ll need the Windows Resource kit for your server; mine is a Windows 2003 box. Get it here : Windows Server 2003 Resource Kit Tools and copy / move instsrv.exe and srvany.exe in the same directory of ClamAV (C:\ClamAV).

6. Goto DOS prompt (cmd) and go to C:\ClamAV. Enter:

instsrv.exe clamD c:\ClamAV\srvany.exe

7. Now edit the registry to let clamd.exe run using it’s clamd.conf file when started as a service.

NOTE: It is dangerous to edit the registry, follow carefully

  • Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\clamD
  • Right click on clamd and create a new Key called Parameters
  • Right click on Parameters and create a new String Value called Application
  • Edit the new Application REG_SZ and add c:\ClamAV\clamd.exe -c c:\ClamAV\clamd.conf

8. Then you can start and stop clamD in Services or manually:

net start clamD

You can check if clamav is listening at the right port:

netstat -a | findstr 3310

9. Time to tell Kerio Connect / Mailserver that we have a running ClamAV daemon, ready to answer all AV questions:

  1. Open the Kerio Connect’s Administration
  2. Go to Configuration->Content Filter->Antivirus
  3. Enable option “Use external antivirus” (near the top)
  4. Choose “Clam Antivirus”
  5. Click “Apply” (near the bottom) to save settings

And that’s it !

Mount and format exFAT disks in Ubuntu

Posted on by
9

In this guide, I’ll show you how to enable exFAT support in Ubuntu 10.04 – 11.10 (12.04 might work too, didn’t test it):

Open your terminal and enter:

sudo add-apt-repository ppa:relan/exfat
sudo apt-get update
sudo apt-get install exfat-utils fuse-exfat

That’s it. To get auto-mount support, use these procedures for 32bit or 64bit:

sudo apt-get -y install ncurses-dev
wget http://mirror.gbxs.net/pub/linux/utils/util-linux-ng/v2.18/util-linux-ng-2.18.tar.bz2
tar xf util-linux-ng-2.18.tar.bz2
cd util-linux-ng-2.18
./configure
make

Now follow these steps if you have a 32bit system:

sudo mv /lib/libblkid.so.1.1.0 /lib/libblkid.so.1.1.0.backup
sudo cp shlibs/blkid/src/.libs/libblkid.so.1.1.0 /lib/
sudo chmod 644 /lib/libblkid.so.1.1.0
sudo rm /lib/libblkid.so.1
sudo ln -s /lib/libblkid.so.1.1.0 /lib/libblkid.so.1

or these for 64bit:

sudo mv /lib64/libblkid.so.1.1.0 /lib64/libblkid.so.1.1.0.backup
sudo cp shlibs/blkid/src/.libs/libblkid.so.1.1.0 /lib64/
sudo chmod 644 /lib/libblkid.so.1.1.0
sudo rm /lib/libblkid.so.1
sudo ln -s /lib/libblkid.so.1.1.0 /lib/libblkid.so.1

Now connect your disk or remount it. And you’ll should see your exFAT disk!

Some extra commands:

To format a exFAT partition:
sudo mkfs.exfat -n LABEL /dev/sdXn
or
sudo mkexfatfs -n LABEL /dev/sdXn

To change the label:
sudo exfatlabel /dev/sdXn NEW_LABEL

Get filesystem info:
sudo dumpexfat /dev/sdXn

To check the partition:
sudo fsck.exfat /dev/sdXn
or
sudo exfatfsck /dev/sdXn

Adding ssh-id-copy to OSX !

Posted on by

There’s a very convenient shell script bundled with some distributions of OpenSSH called ssh-copy-id. It seems not to be the case with Leopard’s or Lion’s SSH.
In order to get it, we can simply check it out of a GIT repository. Execute these two commands:

sudo curl 'https://raw.github.com/gist/1639381/eea46277ba544fcbd0a0768e8b3f854880ddb772/ssh-copy-id' -o /usr/bin/ssh-copy-id
sudo chmod +x /usr/bin/ssh-copy-id

Now execute ssh-id-copy like this:

MBP:~ martijn$ ssh-copy-id root@192.168.0.7
Now try logging into the machine, with "ssh 'root@192.168.0.7'", and check in:

~/.ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.

Loading drivers in ESXi 5.0

Posted on by
Reply

So I upgraded to 5 from 4.1 – Cool. Almost. Vanilla install had no support for my Promise SuperTrak EX-8654 card which I have in my HP MircoServer. Now what?!?!?
Well, after a lot of searches, the solution was actually on the Promise site! Yay for them!

So in short an example of you to load a driver on esxi 5.0.

1) Enable ssh access on your esxi 5 host (what do you mean you’ve already done that? It’s dangerous!)

2) Get you driver. The 8654 driver I got from the Promise support site was called 'scsi-stex-4.07.0000.75-1OEM.500.0.0.472560.x86_64.vib'. Yep, what’s in a name.

3) Copy over the driver to the host using scp
ex: scp <driver name> root@<esxi_5_host_ip>:/tmp

4) Next ssh to the esxi host, go to /tmp

5) Install the driver
esxcli software vib install -v /tmp/<driver name>

6) Reload the esxi host – Oh I hand’t told you? Well you need the driver right?

7) Then ssh to the esxi host and check if the driver loaded with 'esxcli software vib list'
In my specific case it looked like this:

~ # esxcli software vib list
Name        Version                             Vendor   Acceptance Level  Install Date
----------  ----------------------------------  -------  ----------------  ------------
scsi-stex   4.07.0000.75-1OEM.500.0.0.472560    Promise  VMwareCertified   2011-12-26

8) Sit back and enjoy the fact you have access to the disks again for adding as a datastore.

Adding a non-VMFS drive to your ESX(i) server and use it!

Posted on by

I had some spare Windows drives lying around and wanted to put them in my HP MicroServer running ESXi 4.1.

After installing the SATA drive, and rebooting, I tried to simply add the drive in the vSphere console. No love from VMWare — I got the message, “Error while adding drive – disk not available.” Hmmm. I was sure the drive was working.

Turns out that in ESXi, once a disk has been written to, in any format, it won’t initialize.
Here’s what it took to add the drive in:

Low-level formatted the drive (the name of the drive might be shorter or longer):
~ # dd if=/dev/zero of=/vmfs/devices/disks/t10.ATA_ST3500413AS_Z2A3TKQ6 bs=512 conv=notrunc

Try adding the disk to your datastore now; I canceled this command after waiting 5 minutes and noticed that ESXi now saw the disk as a ‘blank disk’. Adding it to my datastore now worked! If not, continue…

Recreate the partition table:
~ # fdisk /vmfs/devices/disks/t10.ATA_ST3500413AS_Z2A3TKQ6

Then ‘o’ to Create a new empty DOS partition table
Then ‘n’ to add a new partition. I used Primary as the type, and 1 as the partition number.
Then ‘t’ to change the type. ‘fb’ is the code for VMFS 3.0
Then ‘w’ to write everything to the drive

Finally, use the ‘vmkfstools’ program to create the volume. I added it as a new datastore using the following command:
~ # vmkfstools -C vmfs3 -S Datastore2 /vmfs/devices/disks/t10.ATA_ST3500413AS_Z2A3TKQ6

As always, YMMV.
