Middleware: Oracle HTTP Server(OHS)
Version: 12.2.1.3
Configured Oracle HTTP Server(OHS) in standalone mode. Node manager is running perfectly. While starting "./startComponent.sh ohs1" i am getting the below error,
"""
javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
Error: Error occurred while performing nmConnect : Cannot connect to Node Manager. : Unrecognized SSL message, plaintext connection?
"""
The solution found in internet is to changing the SecureListener to false in Nodemanager properties file.
When i did that i got the below error,
"""
weblogic.nodemanager.NMConnectException: Connection refused (Connection refused). Could not connect to NodeManager. Check that it is running at localhost/XXX.0.X.X:XXXX.
Error: Error occurred while performing nmConnect : Cannot connect to Node Manager. : Connection refused (Connection refused). Could not connect to NodeManager. Check that it is running at localhost/XXX.0.X.X:XXXX.
"""
And the solution for this is Setting the SecureListener to true in node manager properties file.
I am confused. Can someone help in resolving these errors?
Installed Oracle Access Manager(OAM) and OHS on same machine, but installed OHS in Standalone mode in different folder. After that, uninstalled OHS and Installed OHS in the same folder where i installed OAM, It worked.

Configuring a ELK stack version 8.1, based on two virtual machine which both run Oracle linux 8. I need to send logs from a VM to the other using rsyslog. On the recieving machine logs will be acquired using FileBeat. The file rsyslog.conf has been configured on the sending machine, adding target machine parameters. The file filebeat.yml has been configured to recieve logs from rsyslog like this:
- type: syslog
enabled: true
format: auto
protocol.tcp:
host: "X.X.X.X:10514"
The firewalld on the receiving machine has been configured opening the port 10514.
Since the reboot after configuration, the only thing I can get is the error:
cannot connect to X.X.X.X:10514: Connection refused
How can I solve this problem?
I have recently downloaded the oracle database 12c enterprise edition. So I got Oracle SQL developer installed with the package. I started to create new database connection as given in the documentation.
My problem is....
When I try to test or connect with the following field values:
Hostname: localhost
Port: 1521
SID: orcl (I have tried 'xe' as well but the error persists.)
I get the following error:
Status: Failure -Test failed: IO Error: An existing connection was forcibly closed by the remote host, connect lapse 15080 ms., Authentication lapse 0 ms.
I have also tried to use different port numbers but the issue remains the same. Don't know what went wrong.
If local server sqlplus connection is fine, and error occurs only for remote client such as sql developer, check your sqlnet.ora file to see if it has tcp.validnode_checking = yes. Valid Node Checking allows or denies access from specified IP addresses to Oracle services. Set tcp.validnode_checking = no and restart database listener should solve issue.
Change the connection setting to Connection Type=Basic and use SID (not Service Name).
If you use Connection Type=TNSNAMES or Service Name instead of SID - the connections will be dropped.
I am using ubuntu server with vsftpd service, connecting over SSL. When connecting using Filezilla randomly getting below error.
Error: GnuTLS error -15: An unexpected TLS packet was received.
Error: GnuTLS error -15: An unexpected TLS packet was received.
Error: Failed to retrieve directory listing
It will be okay after restarting vsftpd service and will again showing after some days. tried reinstalling vsftpd service and regenerated certificate.
Here is my /etc/vsftpd.conf`
rsa_private_key_file=/etc/ssl/private/vsftpd.key
rsa_cert_file=/etc/ssl/private/vsftpd.pem
ssl_ciphers=HIGH
pasv_enable=YES
pasv_max_port=12110
pasv_min_port=12099
port_enable=YES
pasv_address=<ip>
ssl_enable=YES
allow_anon_ssl=NO
force_local_data_ssl=YES
force_local_logins_ssl=YES
ssl_tlsv1=NO
ssl_sslv2=NO
ssl_sslv3=NO
require_ssl_reuse=NO
allow_writeable_chroot=YES
pasv_promiscuous=YES
I have tried both active and passive mode and using ec2 instance and ports are opened on security groups. Tried same time different ISP ips and different location( not a local firewall issue).
Added the line seccomp_sandbox=NO on /etc/vsftpd.conf file solved my issue.
This is just to share my problem and solution to everyone.
I setup the plugin with the instructions from
https://wiki.jenkins-ci.org/display/JENKINS/Team+Foundation+Server+Plugin
First problem:
FATAL: com.microsoft.tfs.core.exceptions.TECoreException: Connection refused
java.lang.RuntimeException: com.microsoft.tfs.core.exceptions.TECoreException: Connection refused
Second problem:
FATAL: com.microsoft.tfs.core.exceptions.TECoreException: Unrecognized SSL message, plaintext connection?
java.lang.RuntimeException: com.microsoft.tfs.core.exceptions.TECoreException: Unrecognized SSL message, plaintext connection?
First problem:
FATAL: com.microsoft.tfs.core.exceptions.TECoreException: Connection refused
java.lang.RuntimeException: com.microsoft.tfs.core.exceptions.TECoreException: Connection refused
This is due to the firewall between my Linux Jenkins server and the Windows TFS server. I had Network team open the port 8080 and 443 from the Jenkins server to the TFS server.
That fixed the first problem.
Second problem:
FATAL: com.microsoft.tfs.core.exceptions.TECoreException: Unrecognized SSL message, plaintext connection?
java.lang.RuntimeException: com.microsoft.tfs.core.exceptions.TECoreException: Unrecognized SSL message, plaintext connection?
This is due to my incorrect URL to the TFS DefaultCollection
I used the https for "Server URL". This will demande a SSL certificate to be install on the Jenkins linux server.
https://swcosvctfs01.wco.int:8080/tfs/DefaultCollection/
After switching to http as below, the error went away, and Jenkins was able to checkout a copy of the TFS sourcecodes successfully.
