Make sure that when you send mail from web hosts you have a reverse lookup name that matches your postfix banner. Otherwise you can sometimes get marked as spam by some providers. Use the following to set the postfix name: postconf -e myhostname=servername Where ‘servername’ is the name of your PTR record. Remember to restart postfix once you have made this change. You can check this with netcat or telnet:

The virtual appliance you can download already has the correct udev rules which usually cause this situation (see here). There is a file in vyatta which has a record of the specific interface information. When you migrate the machine, this record causes the machine to think the adapters have changed. Edit the following file: nano /opt/vyatta/etc/config/config.boot You can either remove the interfaces section or edit the interfaces to suit i.e. change the MAC addresses etc.

Once you have run a service pack on a server and you try to add a server role, often it will not accept your original source disk. In this case you need to extract the service pack files. For example in the case of Windows 2003 Server SP2, use the command prompt with /x switch to extract the files: WindowsServer2003-KB914961-SP2-x86-ENU.exe \x:c:\path-to-folder Once it has extracted the files try to add the server role, this time hopefully with success.

Log into the linux guest and make sure you have hwlist installed. If you haven’t you can install it with: sudo aptitude install hwinfo Once that is installed run the following: sudo hwinfo –framebuffer This returns all the compatible modes: 02: None 00.0: 11001 VESA Framebuffer [Created at bios.450] Unique ID: rdCR.O3PgoQaqFo1 Hardware Class: framebuffer Model: "VMware virtual machine" Vendor: "VMware, Inc" Device: "VMware virtual machine" SubVendor: "V M ware, Inc.

Just press the home button and press the power button:

This is a bit of pain when you are using VMware and Ubuntu as every time there is a MAC address change udev will create another adapter i.e. eth0 will become eth1 and eth0 will seem to disappear. To stop this behaviour add this: ENV{MATCHADDR}=="00:0c:29:|00:50:56:", ENV{MATCHADDR}="" To the following file /lib/udev/rules.d/75-persistent-net-generator.rules

Why oh why do I ALWAYS forget: sudo a2enmod rewrite Every single time it’s the same old run-around which leads to: sudo a2enmod rewrite aaaaaaaa, remember remember remember…
