Can someone refer/suggest me documents/resources to achieve this kind of setup for my single application running on Weblogic 12c? If there is any good resource for this to get this done step by step please share. I am looking for a continuous highly available architecture.
I have tried bringing up both of the servers and enabled the apache redirection to both the servers so that all incoming requests are shared between 2 servers, however the hazelcast client gets disconnected, or the active starts to throw a lot of exceptions and the components go down every time I bring up 2 production servers having mostly the same configurations. And I believe in my current setup only 1 weblogic server can be enabled to run at a particular instant, I am trying to change this so that I can have 2 active servers running at the same time.

I want to change the Kubernetes server endpoint port.
I am currently using port 6443 and would like to change it to port 7443.
Kubernetes is installed on-premises and is a single master node.
You can change the default secure port by passing the --secure-port flag when you start your k8s api server.

In the features of windows 7 we have both telnet client and telnet server. But in windows 10 telnet server is not available, Can anyone please guide on how to install it? And I am also aware that we can use ssh instead of telnet.
Microsoft deprecated Telnet Servers in Windows Server 2012 R2, and subsequently in Windows 10.
Telnet is considered completely insecure these days, because it sends everything across the wire in plain text, so they removed it.
Since you'd need to install a 3rd party Telnet server, you should (instead) consider installing a SSH server. Similar abilities and results, but SSH is generally considered secure.
Perhaps check out this Serverfault question for some suggested SSH servers:
What is a good SSH server to use on Windows?
(Answer from #Ƭᴇcʜιᴇ007 found HERE)
I know I am a tad late to this feed, but I have used the GSW Telnet Server and SSH Server and they have been great. They claim to be the most secure SSH on the market and I have never had any issues with data security at all.
They do have 24/7 support and can help with installation if there are any difficulties.
Hope this helps - Ben

I have a small sample application which send some data to the server and close the connection afterwards. I ran it on my localhost as server & client and it worked.
When I ran the same code after changing the IP to another host(running Cent OS in VM) as server and my client (Ubuntu), I get the following error from client binary.
client.c : 47 Error connection to remote machine
139915881411416:error:02002071:system library:connect:No route to host:bss_conn.c:246:host=192.168.56.101:6001
139915881411416:error:20073067:BIO routines:CONN_STATE:connect error:bss_conn.c:249:
I am able to ping the remote server from my terminal. Any suggestions or solutions are welcome :) .
Actually the problem was because of firewall running on server(Cent OS). After stopping the firewall using command,
service iptables stop
the client was able to make a connection with the server.
Better Solution (without stopping firewall):
Add your client's IP address in the iptables so that it will allow the client to connect to your server without stopping firewall.
iptables -I INPUT -s <client_ip_address> -j ACCEPT

Using CentOS 6
I have 2 Apache httpd services running. The first one provides REST interfaces and a UI to manage the operating system (start/stop services, execute system command using suid, modify system settings, etc.). This httpd service (running on port 5555) will only be accessible from a certain ip range (firewall) since it will be used for administrative purposes.
The second httpd service (port 80 and 443) will be visible on the Internet. It will serve a web application to external customers.
The first httpd needs selinux policies that give it more access to the OS files/processes. The second needs selinux policies that are strict to what it is allowed to do within its context. The second needs to be this way for better web application security and prevent any web app exploits from even being able to touch the OS.
Both of the httpd processes are running as different users.
Can selinux be used with 2 different sets of policies for the same httpd executable?
How do I/is it possible to set the httpd process context to switch to another set of policies when httpd starts?
Is it just a matter of making a copy of the httpd binary and change its selinux context that uses all new policies (relabel the httpd binary, but I'm sure it will take more than this)?
What are the steps to copy the existing httpd selinux settings to a new name?
I think this comes down to needing a httpdpublic and httpdprivate selinux context. Anyone done anything like this before that could give some guidance or suggest alternative solutions? Thanks

I was looking for a service paid/free which will enable me to run my Perl script(which has a considerable run time) remotely through a web interface or run it periodically like a cron job. Is there anything like that ?
Just buy some VPS (Virtual Private Server) hosting plan.
A VPS Web hosting plan means you share the physical server hardware with other websites, but you are allocated a dedicated slice of the system resources.
With VPS you can configure your own cron jobs, install Perl libraries, execute Perl scripts, ... all with your own root.
There are many VPS hosting providers. Google for them. For example $6.00 per month will give you a basic Linux VPS with Interserver.Net.
