My company makes me rotate my laptop each year.
I am trying to re-install ipython with notebook (it worked just fine like this before).
According to the command prompt, everything is hunky dory.
[NotebookApp] The IPython Notebook is running at: //127.0.0.1:8888
[NotebookApp] Use Control-C to stop this server and shut down all kernels.
But, Chrome can't connect to //127.0.0.1:8888/
I have a suspicion that it is a versioning problem with tornado, but was wondering if anybody else had faced similar issues?
The problem was not with ipython, but rather with the antivirus that had been set by a company policy to block localhost servers. This was resolved by a call to the IT department to ask them to remove the offending business rule from my computer.
It is worth noting two things:
(1.) ipython notebook --debug
this provides a lot more detail on what is happening behind the scenes, and provides a place to start problem solving from (although dont be thrown by the config error, that is a red herring)
(2.) in the command line this is what a successful connection looks like:
[NotebookApp] Kernel started: 77bb1680-ef54-4bf2-b9be-dc49dab639d7
[NotebookApp] Connecting to: tcp://127.0.0.1:52601
[NotebookApp] Connecting to: tcp://127.0.0.1:52603
[NotebookApp] Connecting to: tcp://127.0.0.1:52600
[IPKernelApp] To connect another client to this kernel, use:
[IPKernelApp] --existing kernel-77bb1680-ef54-4bf2-b9be-dc49dab639d7.json
In my instance all i got was:
[NotebookApp] Kernel started: 77bb1680-ef54-4bf2-b9be-dc49dab639d7
This will tell you that there was a problem connecting through to the client.

I'm currently trying to develop a cloud in my pc using virtual box. The idea is that I have 2 virtual machines, one which devstack installed (all in one) and the other with osm mano. Right now both have everything installed. Hence, I can log in to mano via user and password 'admin' as well as to devstack.
Current properties:
VM1 (devstack): IP (enp0s8) -> 192.168.56.101
Login to 192.168.56.101 -> correct
VM2 (mano): IP (enp0s8) -> 192.168.56.105
Login to 192.168.56.105 -> correct
As some of you may guess, I have 2 network interfaces in every vm, the first one being NAT (enp0s3 with 10.0.2.15 IP) and the second one being Host Only (192.168.56.x according to virtual box).
Needless to say, I can ping from one virtual machine to another without any problem.
Now, in the past I've being using devstack (ubuntu 18.04) in order to play with it a little bit, learn how to deploy instances, create groups and so on. Indeed, I developed a topology with an instance as a router and nagios as the monitoring tool system. It worked and I learnt a lot!
Anyway, what I want in this case is starting from scratch (scratch meaning having downloaded mano and devstack but without going further). So here I am, trying to integrate OSM with Devstack, making use of osm-vim command as it is:
osm vim-create --name openstack-site --user admin --password my_openstack_password --auth_url http://192.168.56.101:5000/v3 --tenant admin --account_type openstack
In this case, my openrc file (downloaded from horizon) resulted in my auth_url being:
export OS_AUTH_URL=http://192.168.56.101:5000/v3
What I'm trying to get my head into is how it's possible that this doesn't work, as whenever I log-in to mano web interface (after osm-vim command) I go to VIM accounts and operational state equals to "error".
Any kind of help would be much appreciated, as I've being struggling for a week now.
Thanks in advance!
I had the same problem. At the beginning I thought It was a network problem, but finally I found out It was due to a SSL problem. The most easy solution is to put a specific flag to avoid the SSL verification until the developers fix it. "--config '{insecure: True}'"
I also encountered this problem when I finished installing OSM-10 and OpenStack-Ussuri for Ubuntu18.04 some days ago. I solved this problem by change the url "--auth_url http//:192.168.23.18:5000/v3" to "-- auth_url http//:controller:5000/v3" and put "192.168.23.18 controller" in the ro container "/etc/hosts". The "controller" here is the host name where you install your openstack and which is used is your keystone authentication urls. Maybe you also have solved this problem but this problem is so troublesome and I hope more people do not be annoyed at this~
I'm working on an app with a team. They are able to log in fine when running it on their local servers, however when I try to do so I get 'Invalide username / password' and no network activity or console errors in dev tools.
I have no idea why this could be, we're working on the exact same code - clearly it's something on my machine.
Has anyone come across anything like this before?
(Have tried other browsers and still nothing).
Maybe you need to check your server instalation on your machine.
For example, if you are using XAMPP to manage your Apache maybe there is some configuration that was set in the wrong way.
My advice is, save your code and re-install your server, pay attention to all configuration details and see if the problem is solved.
Annoying issue...

I am trying to connect to couchbase server but its causingfollowing exception. Problem is that everything was working fine and this issue has starting coming from no where. I hope its nothing to do with some port configuration or related to it...
If some one have any useful information over this, Please share with me. in the mean time, I am also looking into the issue.

I tried connecting to the same couchbase server from a sample program from my local windows box, It worked as expected.
Got the reason. I was using -d64 option while calling my java program. unfortunately, the couchbase sdk I am using was only supporting 32 bit.
I removed the -d64 option and it ran fine.
I have some problem with my wso2-esb, it is on a remote linux server and seems to be succesfully started:
But when I try to access it, does not work:
I am not any expert in servers, it is the first time I do such thing, so I probably missed some basic step or something you might know.
Please suggest
Thanks a lot
SOLVED the server was firewalled, I had to add an exception to access it
Two things might be happening.
IE is masking an HTTP error response with its friendly errors.
Since this is a remote server, iptables could be running on the server, or there is another firewall in the way blocking that port.
To diagnose, I would start by disabling friendly error messages in IE, or using a different browser that doesn't do this. Instructions on how to disable it here: http://technet.microsoft.com/en-us/library/cc778248(v=ws.10).aspx
Next, if that doesn't resolve it, I would try running curl/wget on the server, and requesting the displayed URL. curl can be run with curl example.com and wget wget -qO- example.com, both will displayed the returned data (if any) on the terminal. If one returns a command not found, try the other. If that doesn't work, something is going on with your server. If it's returning something that looks like an error (e.g. a sever generated error page), I'd look into that too at this step.
If you appear to have connectivity issues, you can see if there's any iptables rules in place by running iptables -L on the server. A DROP all under Chain INPUT would cause this. You can read more about iptables here, and how to set it up for your needs here: https://help.ubuntu.com/community/IptablesHowTo (Even if you're not using ubuntu, this will still work for you, look in the "Allowing Incoming Traffic on Specific Ports" section, there's an example there you would need to adopt slightly for the non-standard port the server is running on). If there's an external firewall preventing access, you would need to talk with whoever is managing the sever.
Its seems some network issue. Can you try to ping the IP. If you cannt ping that means the machine is not reachable.

I have the c:\Program Files\Myexe.exe on the Server1
I run BIDS package on MyPC1 and can't start it.
On the server in the task manager I see the process started, but it hangs, possibly because of the security warning.
Thank you,
Nikolz
If you see the program start, then you have successfully started it!
You now need to find out why it hangs. What security warning are you referring to?
Does the program have a UI? If so, it won't work very well if started remotely - which user do you want it to talk to?
