• How to start networking on a wired interface before logon in Ubuntu Desktop Edition

  - by Burly

  Problem Ubuntu 9.10 Desktop Edition (and possibly previous versions as well, I haven't tested them) has no network connections after boot until at least 1 user logs in. This means any services that require networking (e.g. openssh-server) are not available until someone logs in locally either via gdm, kdm, or a TTY. Background Ubuntu 9.10 Desktop Edition uses the NetworkManager service to take commands from the nm-applet in Gnome (or it's equivalent in KDE). As I understand it, while NetworkManager is running at boot, it is not issued any commands to connect until you login for the first time because nm-applet isn't running until you login and your Gnome session starts (or similar for KDE). I'm not sure what prompts NetworkManager to connect to the network when you login via a TTY. There are several relevant variables involved in starting up the network connections including: Wired vs Wireless (and the resulting drivers, SSID, passwords, and priorities) Static vs DHCP Multiple interfaces Constraints Support Ubuntu 9.10 Karmic Koala (bonus points for additional supported versions) Support wired eth0 interface Receive an IP address via DHCP Receive DNS information via DHCP (obviously the DHCP server must provide this information) Enable networking at the proper time (e.g. some time after file systems are loaded but before network services like ssh start) Switching distros or versions (e.g. to Server Edition) is not an acceptable solution Switching to a Static IP configuration is not an acceptable solution Question How to start networking on a wired interface before logon in Ubuntu Desktop Edition? What I have tried Per this guide, adding the following entry into /etc/network/interfaces so that NetworkManager won't manage the eth0 interface: auth eth0 iface inet dhcp After reboot eth0 is down. Issuing ifconfig eth0 up brings the interface up but it receives no IP address. Issuing dhclient eth0 instead Does bring up the interface and it Does receive an IP address. Completely removing the NetworkManager package in addition to the settings above. I'm a bit confused with the whole UpStart/SysVinit mangling that's going in Ubuntu currently (I'm more familiar with the CentOS world). However, directly issuing sudo /etc/init.d/networking start Or sudo start networking does not bring up the eth0 interface at all, much less get an IP address.

• How can you use Windows Backup with a TrueCrypt encrypted backup destination?

  - by Burly

  Background There are numerous backup solutions out there for Windows and they come in many different forms. From a file copy and/or syncing tool like SyncBackSE to whole hard drive backup utilities based on Volume Shadow Copy like Acronis TrueImage or Norton Ghost to block level copy tools like dd. Each of these solutions offers different pros and cons versus the "Windows Backup and Restore Center" feature built-in to Windows Vista and Windows 7. I am not interested in discussing alternative backup solutions here however, as that has already been covered by numerous other questions. Contraints There are two "types" of backup supported by the "Windows Backup and Restore Center"(WBRC): - File backup (which Windows calls "Back Up Files") - Full System Backup (which Windows calls "Complete PC Backup) I am interested in a solution which supports either and/or both types of backup with WBRC. Questions How can you use a TrueCrypt encrypted mount point as the destination for the built-in "Windows Backup and Restore Center" feature in Windows Vista and 7?

• Outlook 2010 search stopped working with Exchange 2007

  - by Steve Hiner

  The quick search feature in Outlook 2010 used to work fine. We switched the computers over from a workgroup so that they are on the domain with our new server. We then copied all the email from the old PST file into the new Exchange based folders. Since we did that 3 of the 4 computers can't search email using Outlook's awesome search boxes. One of them works perfectly fine. Any idea what might have happened? There are only 5 users on the network and it's a pretty burly server for such a small network, I can't imagine the server is still indexing their mail. Is the quick search something that has to be turned on or might it be related to the permissions change from a non-domain user to a standard domain user?
