Servus Robots couldn’t have had the success they experienced in transitioning from their DSL line to a dial up connection without the Mac OS, Sustainable Software’s IPNetRouter, and a computer with both a built-in modem and Ethernet port (a PowerBook).
This set-up saved Servus Robots during a five-day ISP outage caused by the Code Red worm. The company makes a robotic floor cleaning system that utilizes sonar guidance, wraparound touch sensors, electronics, computer systems, and high quality cleaning components. Like many modern companies, Servus Robot relies heavily in its Internet connection. And when their ISP went down, that was very bad.
“However, by using my PowerBook, IPNetMonitor and IPNetRouter, I was able to sustain Web services via a dial-up connection for the whole company,” David Knuth, director of software engineering, told MacCentral. “It was only 12 machines, but everyone needed to send and receive critical e-mail. We normally use a DSL line with a LinkSys router providing DHCP services.”
IPNetRouter is a software router that lets you share an Internet connection on a single Mac with other Macs, PCs, or Linux systems on the same network. IPNetMonitor is a collection of 12 Internet tools that enable you to monitor your connection to the Internet. See
our June 5 article and the
Sustainable Software Web site for details.
Knuth added that setting up IPNetRouter was simple. Servus Robots has six Windows 2000 machines, two Windows 98 systems, one Windows ME machine, one RedHat Linux systems, an iBook, and a Power Mac G4. Knuth brought in his personal PowerBook to use as the routing machine and Internet access gateway.
“Performance was fine for e-mail and slow (as expected) for Web surfing,” he said. “I’ll be formalizing our Internet access backup strategy to use IPNetRouter on my Power Mac G4. There were no complaints regarding the speed, but plenty of praise that we had an Internet connection again. And because I believe that the Code Red worm is only the beginning, I am making sure to have a back up strategy for Internet access.”
