First of all I need to give thanks to Mrs. Benila to reach me here. Very good response from her for my mail query I had done 2-3 month back. As per the class session point of view you are very lucky to fet a person like Mr. Reji Cyriac , with a good knowledge in linux. Unfortunately I am not able to attend the RHCSS-423 course due to some problem in my client side. So I will back here soon to write the exam and attend the balances module too. Moreover I am very thankful to Mr.Mendus to make a business approved unit with IPSR.
