I am trying to create a MinIO Server and Client so I can run some tests and I am getting the error bellow when I try to run mc:
C:\mc.exe alias set myminio http://169.254.44.236:9000 admin password
mc.exe: <ERROR> Unable to initialize new alias from the provided credentials. Get

169.254.44.236:9000: connectex: A socket operation was attempted on an unreachable network.
I just copied the command given to me when I started the MinIO Server. I am using a Windows10 PC remotely.

This is my first time using Mongodb, It connect normally using the IDE from Mongodb university basics m001 course but when I tried to connect from cmd it won't connect and gives me this error
*** You have failed to connect to a MongoDB Atlas cluster. Please ensure that your IP whitelist allows connections from your network.
Error: Authentication failed. :
connect#src/mongo/shell/mongo.js:374:17 #(connect):2:6 exception:

I added the path to my environment & checked the network access from my Atlas and I can connect to it from anywhere
Can anyone help me with this please??
Whenever I try to access AWS instance by using ssh I the following error:
Connection blocked because server only allows public key authentication. Please contact your network administrator.
Connection to ec2-54-214-97-39.us-west-2.compute.amazonaws.com closed by remote
host.
Connection to ec2-54-214-97-39.us-west-2.compute.amazonaws.com
closed.
I am accessing by ssh enabled command prompt:
chmod 400 virtue.pem
ssh -i "file.pem" ubuntu#ec2-publicIp.us-west-2.compute.amazonaws.com
I am unable to access aws instance vitual machine .
The error is like the one mentioned here:
https://laracasts.com/discuss/channels/servers/ssh-key-no-longer-working
You need confirm that file.pem is the correct key to access to the instances, and use chmod 400 to give permissions to the .pem in your computer. you can view the logs in the AWS console to verify if there is any message about ssh access.
You can launch other instance with other .pem or detach root volume and attach to other instance to validate the config files
This may be a problem caused by (man-in-the-middle attack).
Change your network to a private one and retry!

Hi, I am following a Swift Xcode class, and now we are building a project required to connect with AWS parse server, After tried lots of times, it still the same error: ssh_exchange_identification: Connection closed by remote host
Here is the error message:
luodeMacBook-Air:desktop luo$ chmod 400 onepicioskeypair.pem luodeMacBook-Air:desktop luo$ ssh -i "onepicioskeypair.pem" ubuntu#ec2-18-216-187-86.us-east-2.compute.amazonaws.com ssh_exchange_identification: read: Operation timed out luodeMacBook-Air:desktop luo$
Please verify you are trying with correct ip address or url.
change EC2 setting to Allow all IP address
and restart instance and try again
WAS 8.5 full profile isn't officially supported on OSX by IBM so the only option to perform development from OSX is to install stub runtime and connect to WAS installed remotely. I'm trying to install such scenario but something done wrong and can't connect to my WAS.
There's my installation:
On OSX El Capitan Installed:
RAD 9.5 with WAS 8.5 stub runtime (WebSphere Application Server traditional V8.5 stub)
Installed Virtual Box with Ubuntu Desktop edition 14.04
Ubuntu's hostname: anatoly-ubuntu-vm and it's accessible from host, i.e. ping anatoly-ubuntu-vm works fine
On Ubuntu installed:
WAS 8.5 full profile at /opt/IBM/WebSphere
Created AppSrv01 profile at /opt/IBM/WebSphere/AppServer/profiles
WAS installed with root user, IBM Installation Manager required root permission when was started
My connection settings in RAD:
server name: WebSphere Application Server traditional V8.5 stub at anatoly-ubuntu-vm
hostname: anatoly-ubuntu-vm
Runtime environment: WebSphere Application Server traditional V8.5 stub
Connection type:
I've tried RMI 2809 and SOAP 8880 both options didn't work
Enable the server to start remotely is checked and Select the operating system running the remote server: checked Linux option with my username and password. I've tried my regular Ubuntu account and root, both option didn't work.
Server profile path defined as /opt/IBM/WebSphere/AppServer/profiles/AppSrv01
When I try to start server I get the following exception:
The following problems has occurred when starting the server.
CTGRI0001E The application could not establish a connection to
anatoly-ubuntu-vm .
What am I doing wrong?
UPDATE 1:
After I've written this post I've figured out that SSH server isn't installed and configured at all as described here: Requirements for using Remote Execution and Access (RXA) Now, I've installed and it seems like connecting but stuck at 23% at stage Preparing launch delegate, after a while it throw the following error:
The following problems has occurred when starting the server. The
server may not be started in the correct mode. You can restart the
server to desired mode if it is started. CTGRI0075E A file transfer to
or from the system named [anatoly-ubuntu-vm] timed out before the
transfer could complete. The current timeout interval is set to 240000
milliseconds, and might need to be increased.
UPDATE 2:
As I can see despite error message server is started and I even can connect to web console anatoly-ubuntu-vm:9060/console/ibm but it looks that not SOAP connection, neither RMI connection don't work. When I run Test Connection from Settings overview page in RAD, I get the following error:
The connection failed after trying to use all the available connection
types.
Verify the port values are correct and the server has been started. If
the security of the server is enabled, verify the "Security is enabled
on this server" check box is selected, and the user ID and password
are provided. You can specify this in the server editor or when
creating a new server.
For a Technote with details on the most common server connection
problem, see http://www.ibm.com/support/docview.wss?uid=swg21266028.
The last connection attempt failed with the following exception:
ADMC0016E: The system cannot create a SOAP connector to connect to
host anatoly-ubuntu-vm at port 8880.
UPDATE 3
As #DanielBarbarian guessed I tried to run ./wsadmin.sh -port 8880 and it worked and returned
Connected to process "server1" on node anatoly-ubuntu-vmNode01 using SOAP connector; The type of process is: UnManagedProcess`
This is settings of my ports:
UPDATE 4
When I trying to run telnet anatoly-ubuntu-vm 8880 from OSX host I get the following response (ip address changed to non real due to privacy issue):
anatoly-mac:~ anatoly$ telnet anatoly-ubuntu-vm 8880
Trying 192.168.10.10...
Connected to anatoly-ubuntu-vm

Created new EC2 instance of neo4j via CloudFormation template found here (ubuntu host).
https://github.com/neo4j-contrib/ec2neo
Got the web interface to work fine, and DB is up and running.
Trying to connect with neo4j-shell from my local dev machine, and I am able to establish a connection to the remote EC2 server.
$ neo4j-shell -host ec2-xx-xx-xx-xx.compute-1.amazonaws.com
Welcome to the Neo4j Shell! Enter 'help' for a list of commands
NOTE: Remote Neo4j graph database service 'shell' at port 1337
neo4j-sh (?)$
netstat confirms that a connection has been ESTABLISHED
tcp6 0 0 xx.xx.xx.xx:1337 my.local.ip.add:13785 ESTABLISHED
At this point, I type help, or any neo4j command, and I get no response back from the server. The console just hangs. As soon as I stop the neo4j service on the server, I get the following exception on the client console.

I have made the following change to neo4j-wrapper.conf :
wrapper.java.additional=-Djava.rmi.server.hostname=ec2-xx-xx-xx-xx.compute-1.amazonaws.com
All iptables are "disabled", to eliminate variables. I am able to run neo4j-shell on the server itself, to 127.0.0.1
What am I missing in my network config or neo4j server config?
Try to ssh into the instance and run it there. remote connections have been a pain for a long time because of the underlying Java RMI port handling.
You can also try out cycli which supports http and auth.
