I'm installing openstack ocata following the ubuntu install guide. When I run the command openstack hypervisor list I get the following answer:
The server is currently unavailable. Please try again at a later time.<br /><br />
(HTTP 503) (Request-ID: req-fc57ec04-58a3-4ff6-b3bb-fd055a7c8845)
I'm just getting started with openstack and don't know which logs I should have a look at. So if someone some hints or knows the problem I would be grateful.
It seems like it was a name resolution problem. Had to fix it on our DNS server. Now it works fine.
Thanks for yout effort

I want ask the question.
I want to deploy from github to nginx server using jenkins. Maybe you can help me with this? When i try to add in Jenkins setting Publish over SSH i have error
jenkins.plugins.publish_over.BapPublisherException: Failed to add SSH key. Message [invalid privatekey: [B#2a8ec46d]
I just started to study these technologies and most likely I am doing something wrong. Maybe i need configure my nginx files?
Also please tell me something links maybe with Guid how to deploy from GitHub using Jenkins and Nginx.
check this question from StackOverflow, someone faced the same problem and solution provided.
Check first (in addition of my old answer already mentioned) if you need to add to your SSH daemon config file (/etc/ssh/sshd_config), as seen in jenkinsci/publish-over-ssh-plugin issue 94:
PubkeyAuthentication yes
PubkeyAcceptedKeyTypes=+ssh-rsa

I am using college network behind a proxy server, could that be a problem ?
any suggestions ? Does anybody know where I am going wrong ?
Quickest way to troubleshoot this - on the browser window that houses the broken terminal, do a view source. In there you'll find a URL direct to your console proxy server. Copy and paste that URL into a new window and see if you can hit it directly. I'm guessing a firewall issue...
I have successfully installed devstack on my machine and I get the horizon dashboard. Now, I don't know what to do with it?? I am suppsed to test the OpenStack Services.

I have installed R and Rstudio-server on Amazon AMI cloud and both are running properly as I can type R and get the R-terminal and check whether the RStudio-server is running.
sudo lsof | grep rstudio
Since Port 8787 is not accessible and there is another port something like 6970 open so I have created a rserver.conf file in /etc/rstudio/ But when I try to open RStudio server from my system's web browser I get this error
"No Data Received"
I am not sure what is the issue, any help would be greatly appreciated.
I've been using RStudio on AWS instance (EC2, Ubuntu) for several months, so I hope I can help you. First, could you clarify this part of your post?
Since Port 8787 is not accessible and there is another port something like 6970 open
I suppose you are using EC2, as it seems to be a common one for this purpose. Then, I believe you can open certain ports by configuring security groups in the AWS console (i.e. Network&Security - Security Group). Have you added a rule to allow 8787 (or 6970 if you prefer) inbound?
This worked for me.

Hi I am new to the networking domain.
I have recently bought a WLAN 11n USB adapter by a company named GMYLE.
I had difficulties setting up the same on my ubuntu environment.
The driver cd provided has instructions for installing it on ubuntu but I am finding the installation using command line really confusing.
I tried the GUI method myself.
I went to System->Administration->network tools but the device is not being listed out there?
Is there any specific reason for this?
Please help.
Is there an easier way (GUI method) which could help me in setting up the network adapter on my machine?
Any help would be sincerely appreciated.
Thanks.
While this is off-topic, here's something to help you:
The chipset the device uses is probably RTL8192cu. You can download the drivere here.
You can read about how to install it here and here.
