Set static IP to Linux VM

-
If you are decided to not use DHCP to obtain IP dynamically for your linux box, you can set the IP manually as below.

Edit respecting ifcfg-eth* file of your network card and insert following entries in the file:

for network card eth0:

# vi /etc/sysconfig/network-scripts/ifcfg-eth0

 DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
NETWORK=10.8.227.0
NETMASK=255.255.255.192
IPADDR=10.8.227.50
DNS1=10.8.224.13
GATEWAY=10.8.227.62
IPV6INIT=no
USERCTL=no

And replace you IP, netmask, gateway and dns(if any) with your addresses. 

Reactive your network card or restart you network service:

# ifdown eth0
# ifup eth0

or 

/etc/init.d/network restart

There you can see your new network settings and try t ping your gateway to make sure of connection:

# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:50:56:B7:3B:F7
          inet addr:10.8.227.50  Bcast:10.8.227.63  Mask:255.255.255.192
          inet6 addr: fe80::250:56ff:feb7:3bf7/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:9621 errors:0 dropped:0 overruns:0 frame:0
          TX packets:268 errors:0 dropped:0 overruns:0 carrier:0

Running Docker Wildfly/JBoss Application Server in Debug mode via Eclipse

-
I have recently built the whole Development Environment of Java Enterprise Edition (J2EE) project on multiple Docker containers. It has saved the hassle of setting up a dev env for new developers. All it takes to setup the environment is to clone our github repositories and run the Docker images.

I will explain the setup in a future post.

Build Wildfly Docker Image with Debugging Enabled
So basically in order to run the Wildfly in debug mode, we need to add --debug flag to the Wildfly standalone.sh startup script.

Also we need to expose port 8787 in our image as it's the default port for Wildfly JVM debug mode.

1. Create or change your Wildfly Dockerfile as follows:
$ cat Dockerfile FROM jboss/wildfly:10.0.0.Final EXPOSE8787CMD["/opt/jboss/wildfly/bin/standalone.sh", "-b", "0.0.0.0", "-bmanagement", "0.0.0.0", "--debug"] 2. Build and tag the image:
$ docker build -t wildfly-debug . 3. Run the image either via  docker run:
$ …

Foreman fresh installation issue on Foreman proxy

-
After a fresh  installation of Foreman, I got another weird error while try to add a host to foreman:

# puppet agent --test
Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Failed when searching for node node.example.com: Failed to find node.example.com via exec: Execution of '/etc/puppet/node.rb node.example.com' returned 1:
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run


It turns out that issue is because of foreman proxy that it has not been created during installation.
So need to create it manually. In foreman GUI:
Infrastructure > Smart proxies > add new proxy
or if there is any exist edit it and correct the entry of your proxy FQDN. It's something like https://node.example.com:8443

And again, after try to add new proxy, yet another bug:  Unable to communicate with the proxy: ERF12-2530 [ProxyAPI::ProxyException]: Unable to detect features ([RestClient::RequestTimeout]: Request Timeout for proxy Plea…

After I've implemented the OpenVAS vulnerability assessment system, I've made a complete vulnerability testing on the environment for both Linux and Wintel servers.

The result for the all Linux servers were Red :) Severity 10.0(High). The reason was the OpenSSH version 5.

Test result:
