I am trying to use MySQL Cluster 7.5 version , after opening the web browser and clicking on :create new MySQL cluster", and getting in the "define cluster" page , I write the IP of the remote data node in to the host list field ,but I get error which say "there were errors when connecting to the remote hosts, host 172.16.1.129: couldn't open socket to 172.16.1.129 ,press'ok to continue to the next page anyway, or cancel to stay in the previous page"
I turned off windows firewall options too, but no luck,
what is the cause of this error and how to solve it?
What are the essential steps to install/configure in remote pc (data node).?
Thanks a lot

Did you check this? if you OS supports?
This has nothing to do with supported platforms. My guess is the credentials you used to connect to nodes are bad. In that version of MySQL NDB Cluster autoinstaller you can provide only Cluster-wide credentials, i.e. one credentials for all the hosts. Those credentials could be a) private key without passphrase (idrsa in ~/.ssh) or b) ordinary username/password. Please see html help file that comes with Autoinstaller for details.

I'm trying to log into my FTP account through Notepad++ but I cant get it to connect for the life of me. I know the password and hostname are correct because it works fine in filezilla.
I get the following info in the output:
-> TYPE I
Connecting
-> Quit
Unable to connect
Disconnected
I'm using
NPPv6.5.4
NppFTPv0.24.1
Incase it matters, the hostname is through awardspace.net dck.dx.am connection mode is passive, transfer mode is binary, everything else is default...
Thanks in advance for the help,
Dave
I'm getting the same results. The plugin worked before, it looks it is now broken. Starting as admin doesn't help, too. Maybe you can downgrade it to some older version and retry. If someone has time, he can fill a support request directly at NPP FTP homepage. As problems with this plugin are frequent, I switched to a different solution - see the second paragraph of that post.
EDIT: I've made some plugin diagnostics, please follow here.
Connecting
-> Quit
Unable to connect
No more explanation of the error.
The reason was, remote machine doesn’t allow FTP connections at all!
So Use sftp (select from connetion type)
this will work
I am using Windows 2012 R2 VM machine in Azure. I have read multiple article to setup Filezilla server in this environment. However, I am not successful. Any one faced this issue? Any solution will be greatly appreciated.
Just remember to add Filezilla to Windows Firewall :-)
I'm dealing with the same thing right now. locally the FTP serv works great. remote I cannot establish a passive connection. Based on my research this is because Azure is not set up for Passive-FTP. I am uncertain if we can get FileZilla to operate in a active-FTP mode. Will post back if I ever get to the bottom of it. Mine currently connects and authenticates but 'cannot retrieve directory listing' when it tries to kick over to passive (transfer) mode.
In addition to checking the Virtual Machine endpoints are open, be sure to also add the appropriate Windows Firewall rules if you have Windows Firewall enabled on your Windows VM.
Yes, We can connect to Azure server via FileZilla Client.
Steps:
Login to Azure portal: https://portal.azure.com
Click on App Services.
Select the Site and then click on Get publish profile.
Save the file and open it in notepad.exe.
The file contains 2 <publishProfile> sections. One is for Web Deploy and another for FTP.
Under the <publishProfile> section for FTP make a note of the following values:
publishUrl (hostname only)
userName --------------------------> This is the information you are looking for
userPWD
Add the PublishUrl to Hostname, Username and password in their respective fields.
Connected.

After a long research here on Stackoverflow and on net I didn't found nothing talking about it. As the title say, how can I do that?
For example: I am owner of a hosted website that allow me to manage the database via PhpMyAdmin. When I try to connect to my database via prompt, the connection never go fine. It could be because of OS settings (right?).
How can I do that (in both OSs).
Thanks in advance.
If I understand your question correctly:
You have a website with a MySql database hosted on your providers servers.
When you try to use your local PC installation of MySql from a command prompt, it will not let you connect.
I use dreamhost.com and have a similar setup. If I want to use database tools from my local PC to connect to the database, I have to enter my IP address in the db configuration page under "allowed hosts".
Restricting remote database connections to specific IP addresses protects your database from random hacking attempts.
As for your question about restricting command line execution of a program, that is usually just caused by missing configuration information in the environment variables - leaving the path to the executable out of the PATH variable is a common one. You would still be able to run the program if you enter the full path to it.
It really depends on the error message you get when trying to run the program from the command line.
Hey all,
I'm having trouble with PerfMon on one system out of fifteen in a development environment. Accessing it from the local machine is fine but connecting to it remotely throws a "Cannot connect" error.
Each machine is running Win 2003, is connected to the same domain and I have admin rights to all.
There were some services set to disabled which are normally enabled by default so I've set these to match the other machines on the network - still have the same problem.
Any ideas?
Cheers
**Update**
Ok - I found it was the remote registry service not running correctly causing the above error; Once that was enabled Perfmon is now telling me "No such interface supported".
If I connect through Computer Management, it fails the first time, but the second attempt is successful. Connecting through perfmon fails everytime.
Fixed - for anyone that runs into this issue, hopefully this can help you..
Enabling Remote Registry fixed my first problem.
The second issue, "No such interface supported" turned out to be permissions issues within the registry. Apparently the machine had some pretty obscure permissions set to specific registry keys a long time ago, which are now irrelevant.
Resetting permissions with secedit fixed it up -
secedit /configure /cfg %windir%\repair\secsetup.inf /db secsetup.sdb /verbose
Perfmon counters are now accessible remotely.
We encountered the second issue - "No such interface supported" when attempting to "Connect to another computer" in Performance monitor.
All the rules and services are running.
We found the following:
If the user was added to the local admin group, they were able to connect to another computer (irrespective of belonging to the Performance Monitor group).
If the user was not a local admin and in the performance monitor group - we were unable to connect to another computer via the "Connect to another computer" context menu.
But we were able to add the performance counters. In Performance monitor when you add a counter there is an option to "Select counters from computer". We were able to connect to the counters on the remote machine this way. Also note that if you are planning on data collecting, you would need to set the correct credentials (by default it appears to run under a local system user).
I fixed my case as follows:
Add Firewall rule Performance Logs and Alerts from the predefined rule list.
From client, run the Performance Monitor as the remote user
Eg: runas /user:remote_machine\username "mmc perfmon.msc"
Of course, the user must be at least in the user groups "Performance Log users" or "Performance Monitor Users".
The reason why perfmon.exe do not want to connect to the remote server is, it wants to connect to the Perf Monitor and the Perf Logs (Data collections).
So you have to add the user account to also the Log User group and of course to the Monitor Users.
you don't need to be local admin on the remote server!
I have followed Amazon instructions to the letter and it does not work.
ec2-api-tools-1.3-34128 - this is the api tools that I got from Amazon
Set it up following instructions. Checked everything to make sure I follow instructions. When I try to use it, I only get: "invalid.blabla" depending on what command do I try to use.
Anybody with this problem?
I deleted all my instances and all key pairs.
Created new ones (instance and key pair).
Setup putty all over again like instructions say I should do
(creating .ppk file and everything).
Still the problem remains.
When I try to connect to my ec2 instance using putty
I get "login as : " ????????
Also, I am using windows vista.
Is this a problem.
Thanks
Had this same problem. I found that in putty I had to do three things (only 2 of which are mentioned in the amazon guide at http://docs.amazonwebservices.com/AmazonEC2/gsg/2007-01-19/putty.html)
provide the converted private key in the ssh -> Auth section
provide the dns name or IP
go to Connection -> Data and enter "ec2-user" as the Auto-login username
Hope this saves someone else 20 mins!
Did you make sure that you put "root" as the auto-login account in the "Data" section?
A mistake I made than gave me the same error message was setting
"root#ec2-.eu-west-1.compute.amazonaws.com" as the value in the "Host Name (or IP Address)" field in putty.
You need to specify "ubuntu#ec2-.eu-west-1.compute.amazonaws.com".
