Linux Means Business: Linux for Internet Business Applications

A look at how one company is moving ahead by using Linux to provide Internet services to its clients.
Keeping Current

Keeping daemons and applications up to date on a production server is an important part of security and standards adherence. The widespread availability of Linux news and resources has helped us greatly in this regard. We often found when working with other departments that servers based on other operating systems tended to suffer from version lag. Some NT servers were not patched to protect against the rampant teardrop denial-of-service attack, and we found that a mission-critical HP 9000 box was running daemons from 1994, including Sendmail, which is often a hacker target. Most of the time, the reason for the lag was that updates are not easy to keep track of or even apply for such environments as NT and HP-UX. To some extent it is a matter of system administrator vigilance, but the Linux community makes it exceptionally easy to stay responsible.

However, we recently decided that keeping up the aging RPM set from Caldera OpenLinux 1.1 files was becoming an excessive chore. Our tests had shown some advantages to the features of the GNU glibc library, so we upgraded all of our Linux machines to Red Hat 5.0. Besides problems with Disk Druid and the strange fact that the install doesn't set up the /etc/hosts and in.ftpd files properly, we've been very satisfied with the new distribution. The disadvantage is that we lose the benefit of Caldera's Novell Directory Services client, just as the rest of our organization is migrating to Novell Intranetware.

In all, Ruppman has proven a remarkable test case for the suitability of Linux in real business applications. The exceptional robustness of Linux has enabled us to maintain a high service level within our group, and its flexibility and broad toolset have enabled us to quickly solve a wide variety of problems that would require a lengthy research and a significant investment under other platforms. The most common reservation about Linux from IT types involves technical support, but in almost a year, we have never had to call Caldera or Red Hat. We solved almost every one of our problems with a query on, an excellent Usenet archive and search engine. While I have been very lucky to receive little management interference with my technology choices, I am convinced that if Linux advocates can sneak our favorite OS into a moderately visible application, its low cost and high performance will begin breaking down barriers to its acceptance. I hope my experiences at Ruppman provide some inspiration in that direction.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
