It’s possible to configure this yourself, though. There’s a helpful post at the OpenDNS forums that describes how to configure ddclient on an Endian to automatically update an OpenDNS account whenever your dynamic IP address changes.

Here are a few additional notes that may help:

• You don’t need to query an external website for your IP address, since the Endian box already knows it. Set ddclient.conf with “use=if, if=eth0″ (or whichever NIC is your red zone).
• It won’t work if you set “ssl=no”, so you have to leave it set to yes and install the two Perl SSL modules listed in the post.
• Endian doesn’t have an SMTP server installed, so ddclient can’t send you status e-mails. Comment out the “mail” and “mail-failure” lines to avoid errors.
• Make sure you don’t have any spaces in the OpenDNS network label or ddclient conf file.

To test if it’s working, you’ll need to get a new dynamic IP.

• Turn off your cable or dsl modem.
• Spoof the MAC address on the Endian.
  • On your PC, open a command prompt and type “ipconfig /all”. Copy the value of the Physical Address line. It will look something like 00-4D-B7-D3-5F-03.
  • Go to the Network Configuration wizard on the Endian.
  • In step 4, enter your PC’s MAC into the “Spoof MAC address with” field. Change the dashes to colons so that it looks like 00:4D:B7:D3:5F:03.
• Shut down the Endian.
• Turn the modem back on. Wait 15 seconds.
• Turn the Endian back on.

Once you’ve verified it’s working, you can remove the spoof setting by repeating the steps.

You can rename all the files on the Linux server to their lowercase equivalents with this shell script from Linux Journal.

#!/bin/sh
# lowerit
# convert all file names in the current directory to lower case
# only operates on plain files--does not change the name of directories
# will ask for verification before overwriting an existing file
for x in `ls`
do
if [ ! -f $x ]; then
continue
fi
lc=`echo $x  | tr '[A-Z]' '[a-z]'`
if [ $lc != $x ]; then
mv -i $x $lc
fi
done

Your internal workstation computers will not be able to use the server as a synchronisation source until the LOCAL(0) clock has stable time. This may take up to 15 minutes after starting the NTP daemon.

So thanks to Miles Brennan’s Linux Home Server HOWTO. Not sure why none of the other dozen tutorials I read failed to mention that, but it would have been nice…

du -k / | sort -n | tail -10

via peterbe.com

find /path/to/start/at -mtime -5 -print

find /the/path/to/start/at |xargs grep 'the string' -sl

The search will include subfolders.

After you’ve got the module working working you can just put the database server’s hostname and port in the db parameter of oci_connect(), rather than messing with a tnsnames.ora file.

oci_connect('username', 'password', '127.0.0.1:1521/dbname');

Update: The Underground PHP and Oracle Manual has a lot of information on installation, and also a good section on tuning. oci_pconnect() can be used to create a persistent connection to the database server, rather than creating a new one during each script instance.
