Updating SSH known hosts fingerprints (WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!)
In: Linux
8 Feb 2010If you’ve previously connected to an ssh server on a machine and reformatted or fundamentally changed the OS in some way, the RSA host key will have changed, causing ssh to throw up an ugly error as exhibited here:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host is 8b:ff:a1:b5:32:06:4d:fd:2e:2f:67:80:9e:ba:8d:ff. Please contact your system administrator. Add correct host key in /home/taylorg/.ssh/known_hosts to get rid of this message. Offending key in /home/taylorg/.ssh/known_hosts:2 RSA host key for 192.168.1.100 has changed and you have requested strict checking. Host key verification failed.
All the message says is that the fingerprint for the host that was previously stored no longer matches the target. If you know this is okay and want to clear out the error, the process is very simple – just remove the stored fingerprint.

HOWTO: Create Email Forwarders in Google Apps
In: Google
18 Jan 2010If you’ve signed up for Google Apps, it may not be immediately apparent if email forwarders are supported; fortunately for everyone, they are. But they’re not called “forwarders” and aren’t managed quite like traditional forwarders. Instead, Google Apps provides a much more robust Groups feature which allows greater control over who can send mail and how many people receive it. With just a few steps, we can configure Groups to act just like a traditional forwarder.

If you need to pull in data from an external source ad hoc, using SSIS is often overkill. Instead, SQL Server Import and Export Wizard (called “Import and Export Data” in the Start Menu, but DTSWizard.exe in the filesystem) usually does a good job. This is especially great way to pull in data from users, which typically comes in the form of an Excel attachment. Unfortunately, the providers to import from the newer Office 2007 and 2010 XLSX file format (also referred to as “Open Office XML”) are not available by default and will likely result in a “Microsoft.ACE.OLEDB.12.0 Provider is not registered” error. The fix is as easy as installing the “2007 Office System Driver: Data Connectivity Components” package from Microsoft. This same package will also enable access to Access 2007.

Microsoft Office 2010 Beta posted on MSDN/TechNet
In: Microsoft
16 Nov 2009The new Office 2010 Beta was expected this week and just dropped on MSDN and TechNet. Unfortunately, it does appear to be on the faster “Top Downloads” servers – I’m getting a paltry 450KB/s. The Professional Plus 2010 package is available in both 64-bit and 32-bit flavors; download details for both appear below.
