I've problem when configure zapcat on zabbix 2.0 followed link
http://www.kjkoster.org/zapcat/Tomcat_How_To.html
Then I try to use JMX but an error occured when run :
java -Dcom.sun.management.jxmremote -Dcom.sun.management.jmxremote.port=12345 -Dcom.sun.management.jmxremote.authenticate=true -Dcom.sun.management.jmxremote.password.file=/usr/lib/jvm/java-6-openjdk-i386/jre/lib/management/jmxremote.password -Dcom.sun.management.jmxremote.access.file=/usr/lib/jvm/java-6-openjdk-i386/jre/lib/management/jmxremote.access -Djava.rmi.server.hostname=192.168.2.56 -Dcom.sun.management.jmxremote.ssl=true
and error is :
Error: Password file read access must be restricted: /usr/lib/jvm/java-6-openjdk-i386/jre/lib/management/jmxremote.password
So any solution for me ??
You don't need Zapcat with Zabbix 2.0. Look up using the Zabbix Java Gateway instead: https://www.zabbix.com/documentation/2.0/manual/concepts/java
However for this error. You need to set the restriction on your password conf file to chmod 600.

I have asp.net core application hosted on GCP App Engine. When I try to deploy the application it fails on last step:
Updating service [name] (this may take several minutes)... ...failed
ERROR: (gcloud.app.deploy) Error Response: [9] An internal error occurred while processing task /app-engine-flex/flex_await_healthy/flex_await_healthy>blablabla.wm.1
The exception stack trace show that service running in background couldn't find MySQL table (that table obviously exists).
my app.yaml file:
service: XXX
runtime: custom
env: flex
automatic_scaling:
max_concurrent_requests: 80
min_num_instances: 1
max_num_instances: 1
resources:
cpu: XXX
memory_gb: XXX
beta_settings:
cloud_sql_instances: "XXX:XXXX:XXXX=tcp:3306"
It looks like the application is deployed properly despite the error. This is the only error and backgroud service desn't throw any exceptions at later point. In fact it works properly and can connect to the database.
My guess was that maybe GCP is checking health while the application is not connected do database. So I tried to add liveness_check and readiness_check to app.yaml and configured dedicated /healthcheck endpoint in my application but it didn't make any change.
Any ideas how to fix it and what might be a cause?
Deploying app with new version fixed the issue
I am trying to use UploadObjectExample.java code to upload a file to OCI object storage. I am running into connection timeout error while connecting to the object storage URL. The same config file is used by OCI CLI to successfully upload files to OCI config.
Here is the Error log:

Please test curl -v https://objectstorage.us-ashburn-1.oraclecloud.com from the same machine where the Java client times out, just to make sure there are no connection issues. If it works fine you may try to change the timeout value in ClientConfiguration. You can see more details here: https://github.com/oracle/oci-java-sdk/issues/92
Before creating a support ticket you might also try to create a new issue on github/oci-java-sdk.
without knowing more about the config file (I do not suggest you post it here), your home region and other elements it is very hard to help.
I would suggest you open a support ticket at https://support.oracle.com, making sure that you select the Cloud tab and the Service as "Oracle Cloud Infrastructure".
Are you using a proxy? If so, you may need to use the OCI Java SDK ApacheConnector.
This was an issue with the proxy. This was resolved by using the ash7 proxy.
I am trying to make persistant remote powershell connection from Windows7(32-bit) to exchange Server 2013,such that I can run some powershell commands from My windows7
machine as i am running it on server.
I am following steps from this article https://technet.microsoft.com/en-us/library/dd335083(v=exchg.150).aspx
I had already installed
.net Framework Version 4.5,
Windows Framework 4.0,
and windows already has SP1 installed.
Now, the issue is in running this command
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://ServerName.domain.com/PowerShell/ -Authentication Kerberos -Credential $UserCredential
Everytime it results into an error that is
New-PSSession : [ex13r.corp.local] Connecting to remote server ex13r.corp.local failed with the following error
message : WinRM cannot process the request. The following error with errorcode 0x80090311 occurred while using
Kerberos authentication: There are currently no logon servers available to service the logon request.
Possible causes are:
-The user name or password specified are invalid.
-Kerberos is used when no authentication method and no user name are specified.
-Kerberos accepts domain user names, but not local user names.
-The Service Principal Name (SPN) for the remote computer name and port does not exist.
-The client and remote computers are in different domains and there is no trust between the two domains.
After checking for the above issues, try the following:
-Check the Event Viewer for events related to authentication.
-Change the authentication method; add the destination computer to the WinRM TrustedHosts configuration setting or
use HTTPS transport.
Note that computers in the TrustedHosts list might not be authenticated.
-For more information about WinRM configuration, run the following command: winrm help config. For more
information, see the about_Remote_Troubleshooting Help topic.
At D:\path.ps1:1 char:10

+ FullyQualifiedErrorId : AuthenticationFailed,PSSessionOpenFailed
NOTE
Client machine(Windows7) is not connected to any domain
I added the server to the list of trustedHosts
Set-ExecutionPolicy to remotesigned
Winrm service is also running.
Windows firewall is turned off on both the systems.
My Powershell Configuration after framework 4.0 installation is as follows
Name Value
---- -----
PSVersion 4.0
WSManStackVersion 3.0
SerializationVersion 1.1.0.1
CLRVersion 4.0.30319.18408
BuildVersion 6.3.9600.16406
PSCompatibleVersions {1.0, 2.0, 3.0, 4.0}
PSRemotingProtocolVersion 2.2
My efforts are going in no direction,the error remains the same.Any help would greatly be appreciated.
Thanks!
I am trying to get a sample java application to connect to a Mysql gen2 instance I have in GCP. I use SSL and the ip address is whitelisted. I have confirmed connectivity to the instance using the mysql command line and passing in the client-cert.pem, client-key.pem and the server-ca.pem. Now inorder to connect to it from the spring boot java application, I did the following:
created a p12 file from the client cert and key and added it to keystore.jks
created a truststore with the server-ca.pem file.
Added this code in the main before the connection is created:
System.setProperty("javax.net.debug", "all");
System.setProperty("javax.net.ssl.trustStore", TRUST_STORE_PATH);
System.setProperty("javax.net.ssl.trustStorePassword", "fake_password");
System.setProperty("javax.net.ssl.keyStore", KEY_STORE_PATH);
System.setProperty("javax.net.ssl.keyStorePassword", "fake_password");
For the jdbc url, I used : jdbc:mysql://1.1.1.1:3306/sampledb?useSSL=true&requireSSL=true
However I am unable to connect to the instance and see this error from the java ssl debug:
restartedMain, RECV TLSv1.1 ALERT: fatal, unknown_ca
%% Invalidated: [Session-2, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA]
restartedMain, called closeSocket()
restartedMain, handling exception: javax.net.ssl.SSLHandshakeException: Received fatal alert: unknown_ca
restartedMain, called close()
restartedMain, called closeInternal(true)
I also tried to run
openssl verify -CAfile server-ca.pem client-cert.pem`
and got this output:
error 20 at 0 depth lookup:unable to get local issuer certificate`
Any ideas on what I might be doing wrong?
