Có thể nói đây là cuốn sách khá sâu về Linux của Red Hat cho dân system, mình đã tìm các hãng khác như SuSE, Ubuntu, IBM... nhưng không có các course tương tự, sách này không chỉ tốt cho dân system engineer mà giúp ích cho dân programming nữa. Mình mong muốn có nó từ lâu rồi nhưng search trên mạng hoài thấy chỉ có bản RH442 version 4.1 năm 2005, khá cũ và không được đầy đủ nữa, các bạn có thể download về tham khảo ở link sau:

http://www.filesonic.com/file/1176823194/RH442.p2.rar

Nếu bạn nào cần tài liệu này mình sẽ photo từ sách gốc của mình (đảm bảo nội dung đầy đủ và rõ ràng) gửi các bạn, giá 1 cuốn là 300k (tặng 1 trong 2 cuốn lab Linux Advance)

Ngoài ra mình cũng đang kiếm các sách sau (nếu có đủ tiền sẽ mua về luyện tiếp)

Linux NFS and Automounter Administration
Amazon Amazon
The Exim SMTP Mail Server: Official Guide for Release 4
Amazon Amazon
Anh em nào có 2 sách trên (ebook hay sách đều ok) có thể trao đổi tài liệu với mình

Chân thành cảm ơn các anh em thời gian qua đã mua sách ủng hộ mình, giúp mình để dành lương mua sách (do you believe? it's up to you!)
