When asked how many NICs are installed in the Redhat Machine you are working on, you don’t have to run to the server room to check how many physically have been installed. Actually you don’t even need a screw drive to open the box and figure that out. It seems a lot of people are asking this question on daily basis: “How can we find out how many NICs are installed in our Redhat host without checking it physically?” As with everything else for Linux, there is a command that can do the trick for you and reports all the NIC cards that have been detected by the kernel. Below is all the commands you will need for the task:

Ah it seems virtualization is what going to unite the largest competing vendors. Yes, I am talking about Microsoft, Redhat, and Novell. Not too long back Novell who purchased SUSE has got in an agreement with Microsoft in regards of Virtualization. So with SUSE making the lead seems REDHAT is going the same route as well. I guess there is things where the big players in the IT market have to get a long, and virtualization seems to be  one of the biggest at the moment.

Redhat has surprisingly announced the joint of Microsoft in the virtualization market, and they will provide a validation and certification programs for virtualization solutions. As Redhat announced a good validation & Certification program will allow the customers to deploy a heterogeneous solutions from Microsoft & Red Hat. It seems in few years virtualizations will unlock the boundaries between many competing vendors.

Most companies these days restrict their internet access by forcing the usage of web proxy. If your company is forcing a proxy policy & you are running Redhat/CentOs/Fedora you will have to update your yum.conf to be able to update your desktop or server using yum over a proxy connection. Luckily setting up yum to run over a proxy is an easy task. below is the few steps you need to follow to establish just that.

Edit the file /etc/yum.conf and add the following lines:

  # The proxy server - server: port
  proxy=http://proxy.mydomain.com:3128
  # If proxy authentication is required
  proxy_username=yum_user
  proxy_password=yun_user_password 

The next step is to declare the variable http_proxy to run
when the yum rpm get executed to avoid the below error:

warning: rpmts_HdrFromFdno: Header V3 DSA signature: nokey, key
ID e8562897
