Starting Share Files with NFS

Olexiy and Denis provide an introduction to the features of network filesystem (NFS).
A Word about NFS Versions

While the mount command for the NFS filesystem is working, the version of the protocol is being recognized and a warning message may appear on the screen. Usually it says the NFS version of the server is older than the kernel mechanism.

The idea of sharing files through the Net is as old as the Net itself, so there are concurrent solutions lists. To improve NFS try version 4, or NFSv4 for short, which was introduced in the year 2000. The inventor of NFS, Sun Microsystems, is a sponsor for the Linux NFSv4 Project. It has, of course, all the features of previous releases but supports security by extending the basic RPC security mechanism, so the weakest point of the previous version has been solved. The other weak point, lack of internationalization, does not exist anymore. Speed of transferring has improved due to caching. We also can avoid those procedures of calculating the optimal parameters because the new mechanisms of improving access are supported. Putting this version into practice means going without dust and noise—nowadays the Linux NFSv3 server supports file locking—an NFSv4 feature.

So, don't forget about the old vine on the Net, NFS. It is still not the vinegar of history.


Olexiy Tykhomyrov ( has been using Linux since 1994. He works for the Department of Experimental Physics at Dnepropetrovsk National University and teaches physics and communications. He loves his son Misha who calls him Tiger because some of his father's students are afraid of him. Tiger likes swimming and traveling.

Denis Tonkonog, a former student of Tiger, works in the same place and also likes traveling and fishing with a gun. Friends call him Black Cat but nobody knows why. He may be reached by e-mail at

The example " matches all IP addresses..." should really be " matches all IP addresses". I know it should be obvious, but I scanned the article and spent the next few hours cursing at NFS before I found the "showmount -e" command.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
