PHP 5.3 now requires that you either have a timezone set in your php.ini file or that you pass the desired timezone via the date_default_timezone_set() function before calling the date() function.

How to List Shared Library Dependencies Used by an Application
Every how and then you need to find out what libraries a certain application is using. Log in to your shell prompt and type eg :
ldd `which nano`
You should see a result like:
ldd -v `which nano`

How To Patch vSphere 5 ESXi Without Update Manager
Since vSphere ESXi 5.0 uses the new VIB model the commands and process have changed slightly but the basic concepts are the same.
- Download the patch file you want directly from the VMware Patch Portal
- Ensure that you enable SSH for remote support on the ESXi Host
- Make sure your host is in Maintenance Mode, this is a requirement since you will need to reboot
- Transfer the update file over to the host using FileZilla or SCP to a MOUNTED DATASTORE of some kind. NOTE: There is not enough space to transfer this to a location on the local ESXi Image. It took me a bit to realize this was failing to copy.
- Once you have uploaded the file to a datastore, this is considered a “Local Depot Repository” as opposed to one on FTP or HTTP.

ssh-copy-id and sshd port
For security purposes, I don’t run sshd on the default port (22). This gave me some problems when attempting to use the command ssh-copy-id. Ideally, you’d expect the following to work:
ssh-copy-id -p XXXX -i '~/.ssh/id_rsa.pub' username@host
However, that didn’t do anything but output an error:
Bad port 'umask 077; test -d .ssh || mkdir .ssh ; cat >> .ssh/authorized_keys'
The solution was to enclose it in quotes as follows:
ssh-copy-id ‘-p XXXX -i ~/.ssh/id_rsa.pub username@host’
Hope that helps.
(The above error probably doesn’t make any sense. ssh-copy-id is a shell script. The command that appears in the error message is a command sent to the server via SSH. Feel free to take a look at the file: cat `locate ssh-copy-id | head -n1`)
Another suggested option is:
ssh-copy-id -i ~/.ssh/id_rsa.pub ‘-p xxxx username@host’

Setting Up Chromium in Kiosk mode
Terminal window: “sudo vi /usr/share/xsessions/chromeKiosk.sh” This should bring up another vi window for you to insert the following code:
#!/bin/bash
xscreensaver -nosplash &
cat ~/.config/chromium/Local\ State | perl -pe “s/\”bottom.*/\”bottom\”: $(xrandr | grep \* | cut -d’ ‘ -f4 | cut -d’x’ -f2),/” > ~/.config/chromium/Local\ State
cat ~/.config/chromium/Local\ State | perl -pe “s/\”right.*/\”right\”: $(xrandr | grep \* | cut -d’ ‘ -f4 | cut -d’x’ -f1),/” > ~/.config/chromium/Local\ State
while true; do chromium-browser %u –start-maximized; sleep 5s; done
If you would like to disallow access to the URL bar simply insert “–kiosk” between %u and –start-maximized as shown in the sixth picture on this step.
A few people commented that the inclusion of the “–incognito” switch at the same place as “–kiosk” goes makes it so that you do not have to worry about making the Chromium user profile read only.
After you have created these two files run “sudo chmod 755 /usr/share/xsessions/chromeKiosk.sh” in order to make this script executable.

Virtual SMTP servers with a Postfix Relay – Ubuntu Forums
Virtual SMTP servers with a Postfix Relay
Did you try:
relay_domains = example.com, example.net
and also something you need to know.
you dont need to set the mx record as in the same domain your want it to work for.
let say you need example.net and example.com to be relayed using 80.80.80.80
you are making an A record in the name let say smtp.relayserver-domain.com
and in the mx records of the other domains you set the smtp.relayserver-domain.com
as your mx record.
