I'm running a "plain-jane" P60 pc - all ISA/VLB, no PCI, no plug-n-pray. 32M ram, 1.6G HD, CD, 3.5 floppy D-Link D-220 ethernet card (ISA) Motorola cablemodem ("installed" by RoadRunner) Caldera Open Linux 2.2 (tell me how to ID the kernel and I will).

RoadRunner Midsouth uses only Motorola equipment. The provided a SMC PCI card with the original install, but it's not usable in this hardware. There is no internal modem available. When I originally asked the tech to install on my NT Server, they weren't sure it was a Windows system.... <g>

RR uses 1hr leases on a dynamic system. You normally get the same address every hour, but not if the system is down when your time is up. Very frustrating...

When I config my D-Link with COAS, nothing changes, even after reboot. When I return to COAS after rebooting, the original setting have returned.After manual editing /etc/sysconfig/network-scripts/ifcfg-eth0 as per Caldera Knowledge Base Ref#990713-0004, I get the following COAS settings:PNP configuration - disabled.
Interface address - 0.0.0.0
Network mask - 255.255.255.0
Broadcase address - 0,0,0,255
Default route - disabled
Init at boot time - enabled
These settings work, along with the manual changes, and I can access the 'net via eth0 and RoadRunner.

I have no way of knowing (presently) what address has been assigned by RoadRunner to my modem/connection. I can ping any net address I want, tho the times are slower in many cases than the times returned by my 56K dialup NT box.
