I've read the AWS documentation, created an EMR cluster high version with Hadoop SPark and Livy. Select notebooks, create one, connect it to the cluster, but when its starting it abruptly stops and the message is Cluster ########### does not have JupyterEnterpriseGateway application installed. Please retry with another cluster.
I try to SSH into the master node and pip install it but that fails. Also can't find any solution online. I thought this came out of the box with these clusters. Any solutions to this?
I'm not sure why the change but you need to install JupyterEnterpriseGateway as one of the selected applications for emr-6-x-x, it doesn't make you (and you can't actually select) do this with emr-5-x-x/

Did you run following command:
/scripts/upcp --force
It updates your cPanel/WHM forcefully and fix the issue found, most of the time it does the trick.

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.

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
