I appended AllowUsers with the wrong user to my /etc/ssh/sshd_config then restarted the service. So I can't connect anymore.
Is there a way to recover without physical access ?
You would need to log in locally at the machine in order to fix it, quite simply.
If you have no local access to it, then you're in more dire straights, and need to deliberate with whomever it is that hosts the machine. If it's a server hosting firm, they often offer the possibility to reboot machines into some kind of rescue system, but you'd need to check with the hosting firm itself, since there's no universal formula for such things.

I'm running a Ubuntu VM with VirtualBox and I have both the dkms and virtualbox-guest-additions packages installed. I read in this answer that the system clock should sync with the host automatically with the Guest Additions, but mine doesn't seem to be doing that. What are some possible reasons / how do I rectify this? I've tried searching for this all over but most of the hits I get off Google tell you how to disable the automatic time sync, not enable it.
My host machine is running OS X 10.8, if that's of any help.

With the very limited ChromeOS crosh shell, how do I add a host key to my known_hosts file in ChromeOS.
I don't believe it is possible to add your key to the Chrome OS shell. If you are in developer mode you can add your key. You can also install the Secure Shell app from the Chrome Web Store and add your key within that app. The app is the best way to go if you don't want to use developer mode, although it still has some bugs to work out.

Attempting to configure Apache2 on a new Ubuntu 11.10 web server. Changes to a recent version of Apache has shuffled some config variables around.
"ServerTokens" and "ServerSignature" were previously found in apache2.conf; not anymore.
I have read 2 differing views.
Manually add them to the end of the apache2.conf file, or
Are they being addressed in a different file
Can anyone confirm that #1 is right. Thank you.
All security related settings are in /etc/apache2/conf.d/security
