1. To edit the settings on the phone (e.g. change the TFTP server), you need to unlock the settings by pressing “**#” and then the Settings key. Doing so should make the padlock icon turn to unlocked.
2. You can then edit the editable settings by pressing the “*” key, with the “#” key saving your changes.

451 4.3.5 Error getting LDAP results in map ldapsx: Unknown error 325
sxadmin-scalix@scalix... Deferred: 451 4.3.5 Error getting LDAP results in map ldapsx: Unknown error 325


All of this occurred after I changed my DNS suffix on my new router. To fix the problem, I updated the OMHOSTNAME setting in /etc/opt/scalix/instance.cfg to what the fully-qualified name was et voila! All working when I use the following test code:

echo "Subject: test" | /usr/lib/sendmail -v my@email.com

find path_to_the_directories_you_want_to_link_to -type f -exec ln -s \{\} . \;

This should create a symbolic link for each of the directories it finds in the path provided. Brilliant!

Nice enough.

I managed to get it working using the following steps.

1. On the PC that broadcasts TV, I added passwordless SSH (via this link) for the user that the kitchen PC runs under.
2. On the kitchen PC, I created a script in the /usr/bin called notifier that has the following in it:
   export DISPLAY=:0 && export XAUTHORITY=/home/[KITCHEN COMPUTER USERNAME]/.Xauthority && sudo -u [KITCHEN COMPUTER USERNAME] /usr/bin/notify-send "TV is now broadcasting" 2>&1.

   Most of this is via this page.

3. After adding the same user to the TV PC, I have a line in the TV PC /etc/rc.local that says
   su [KITCHEN COMPUTER USERNAME] -c notifyKitchen
   The notifyKitchen is a /usr/bin script that simply says
   ssh [KITCHEN COMPUTER USERNAME]@[KITCHEN COMPUTER] 'notifier'.

Done and done. When the TV PC boots, it calls this command and the Kitchen PC gets a pop-up notification that TV is running.

But I’ve had a bit of better luck following the howto on OpenVPN.net and have got it so that I currently have a routing connection (not bridged) up and running. So an internal IP address now accesses my server, and I’m able to access the Samba shares, and the VOIP network as well!

Now, I’m just going to work on bridging the network…when I get home!

du -h | grep -v '/' | awk '{print $1}'

Very nice.

UPDATE: once running Service Pack 1, you need to update the patch.

So, I found a way to enable this through Apache. Warning: this will allow anyone who browses to your PC to shut it down without prompting. So use carefully.

Basically, what you need to do is remove the need for admin/sudo access when shutting down as the www-data (Apache) user. To do this, you use a specific command called visudo which specially edits a file containing what commands require admin access.

In short, make sure that the last line in that file is the following:

www-data ALL= NOPASSWD: SHUTDOWN_CMDS

and that there is a line further up that says Cmnd_Alias SHUTDOWN_CMDS = /sbin/shutdown, /sbin/reboot, /sbin/halt.

Then, once this is done, you can have a shutdown.php that has the following code:

<?php
echo exec('sudo shutdown -h now');
?>

Q.E.D.

I found a great link on cloud.net that mentioned Junction – a free app that allows the new(ish) symbolic link functionality to work in Windows.

Using it, I was able to move the whole folder to the D:\, and then use the command

junction C:\Windows\Installer D:\Windows\Installer

to trick Windows into thinking that the folder is still there.

Something I’m used to doing on Linux, but not Windows.

• When installing trixbox (a FreePBX + Asterisk distro based on CentOS), note that the default install option will format all hard drives attached to the system!!!!  It does mention that the drive will be formatted, but doesn’t underscore that everything attached to the system – including USB hard drives – will be lost.  That’s a whole weekend of having to recover from an aborted partial total format of my server!  Use the advanced option from the boot: screen when installing
• The default password for the FreePBX web client admin user (which you should change) is “password” for a username of “maint”. You can change this through the /etc/trixbox/httpdconf/trixbox.conf file.

Some more CentOS tips:

• CentOS is different from Ubuntu/Debian-based systems in many ways. I’m still learning all of them (like yum -y install instead of apt-get install) but some gotchas – like the fact that package names are different (c.f. samba-client

vs. smbclient) – are more important than others.

• To get the prompt in the bash terminal to be more like Ubuntu, either copy the ~/.bashrc from an Ubuntu machine (if you have one) or try this tip:

  echo 'PS1="[\u@\h \W]\\$ "' > /root/.bashrc

• To install Webmin, follow these great instructions:

  wget http://internap.dl.sourceforge.net/sourceforge/webadmin/webmin-1.500-1.noarch.rpm
  rpm -ivh webmin-1.500-1.noarch.rpm

• To play with networking settings (e.g. setting up a static IP rather than DHCP), use system-config-network
• If you install Samba server and want to restart it, it’s under /etc/init.d/smb (not samba).
• If you get an error re: some packages not working (like dahdi), then use yum update to update the lot. Probably a good idea to run that anyway.
• The default MySQL root password is "passw0rd".

More tips to come later.
