I have created a DMGR profile in my host which is successs. On the same host i have created a managed node. Now when i am trying to federate the node to DMGR i am getting below error :
ADMU006E : Exception creating Deployment Manager Connection: com.ibm.websphere.management.exception.ConnectorException: ADMC0016E: The system cannot create a SOAP connector to connect to host **** at port 8879
Now to verify SOAP connection i have run the below command :
** wsadmin.sh -conntype SOAP -port -host **
Running this script from bin in dmgr profile.. it is connecting fine but failing with the same exception when running from bin directory of managed node profile.
To verify further i done the same setup in a different host by creating a dmgr and a node. It was all fine. DMGR profile created and node got federated in one go.
Not sure what exactly is the issue here.
Have verified that my port and hoat details are all correct. Also that my dmgr is running.
Thanks Michal, ephonk for your inputs.
Found the solution to above issue.
Issue was with the java.security file present in the WAS_HOME/java/jre/lib/security location.
In this file the SSL values were as below :
ssl.SocketFactory.provider=com.ibm.jsse2.SSLSocketFactoryImpl
ssl.ServerSocketFactory.provider=com.ibm.jsse2.SSLServerSocketFactoryImpl
We changed to below values and were successfully able to Federate the node to DMGR.
ssl.SocketFactory.provider=com.ibm.websphere.ssl.protocol.SSLSocketFactory
ssl.ServerSocketFactory.provider=com.ibm.websphere.ssl.protocol.SSLServerSocketFactory
May or may not be relevant, but I've seen this when the SOAP port isn't open in the firewall. Are you sure traffic on that port is allowed?

I have a Jenkins build server (v2.77) installed on a windows server 2016 and I'd like to add a mac as a slave node. I set the node to run via "Java Web Start". On the mac side I downloaded the slave-agent.jnlp file from jenkins, but it doesn't connects to the server.
This is the exception:
java.io.IOException: Failed to connect to 37.210.56.16:49693
at org.jenkinsci.remoting.engine.JnlpAgentEndpoint.open(JnlpAgentEndpoint.java:243)

Caused by: java.net.ConnectException: Operation timed out

...
I tried to turn off the windows firewall, to change the TCP port for JNLP agents option in jenkins to fixed/random, but they didn't connected.
Any ideas?
Thanks for help
Finally I found the solution. I rent the server from the google, and in the google cloud console I had to define for this VM instance a firewall rule to accept a specific port number for this JNLP agent connection. Now it's working well.
I am trying to run Cassandra (CQL Shell) and I am receiving the following error, I have tried all the google responses to existing questions, nothing has fixed it so far.
Connection error: ('Unable to connect to any servers', {'127.0.0.1': error(10061, "Tried connecting to [('127.0.0.1', 9042)]. Last error: No connection could be made because the target machine actively refused it")})
Before installing Apache Cassandra, JDK must be installed.
Can you make sure the IP address is set correctly on your rpc_address setting in your cassandra.yaml file, on your cassandra server.
Also, you need to make sure port 9042 is open and available for incoming traffic (if your IT department is setting up servers, it is possible this port is blocked, unless otherwise specified...)
Hope it helps.
I also faced the same issue , but may be the below 2 way's can help :
Option 1 :
In my case i haven't started the Cassandra Server and was directly trying to connect to Cassandra.
(a) Firstly start the cassandra server via cmd --> \bin>cassandra.bat -f
and then
(b) Try to connect to it's node --> \bin>cqlsh.bat -u cassandra
Option 2:
Try changing the rpc_address in your cassandra.yaml file to eihter 127.0.0.1 instead of localhost
or to 0.0.0.0 instead of localhost
and then again start the server from new CMD.
I was hoping someone could help.
I am trying to sftp to a remote server that is behind a firewall. I have a proxy setup and can sftp via the unix terminal succesfully. However when using mulesofts SFTP connector I get a timeout. From research it looks like this is because it is run on the JVM.
Mule comes with wrapper.conf to update any jvm settings so I have set the following settings:
wrapper.java.additional.15=-DsocksProxyHost:hostname
wrapper.java.additional.16=-DsocksProxyPort=1080
When I do this the Mule service no longer runs and get the following error:
WrapperManager Error: Unexpected exception opening backend socket: java.net.SocketException: Can't connect to SOCKS proxy:Invalid argument or cannot assign requested address
Hopefully someone can assist.
Thank you.
Perhaps typo in the
-DsocksProxyHost:hostname
Should be = rather than :.
The port is unnecessary, 1080 is the default. Documentation is here, see section 2.4 for SOCKS

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

I'm trying to run MPI programs on 8 machines, but I get the error
connect to address 127.0.0.1 port 544: Connection refused
Trying krb4 rsh...
connect to address 127.0.0.1 port 544: Connection refused
trying normal rsh (/usr/bin/rsh)
lagrid02: Connection refused
When I run it with a machinefile option, I get the error lagrid03: No route to host where lagrid03 is the neighbouring node connected to master node.
How should I rectify this ?
Regarding your first error, is rsh running on (all) the machine(s)? You'll need rsh or password-less ssh configured (and ask your mpi job launcher use ssh) before you can start jobs on different machines.
The second error indicates that there is no way to reach the machine lagrid03 with the current network config. I guess you have a /etc/hosts entry with the IP addresses for lagrid03, but you do not have an interface configured in that network. For a more detailed answer you'll need to post details about your network configuration.
The issue is with authentication, if you go into the /etc/pam.d/rsh file and move rlogin and rsh to the top and make it look like this, it would work just fine.
/* For root login to succeed here with pam_securetty, "rsh" must be listed in /etc/securetty.*/
auth required pam_nologin.so
auth required pam_securetty.so
auth required pam_env.so
auth required pam_rhosts_auth.so
account include system-auth
session optional pam_keyinit.so force revoke
session include system-auth
