Red Hat gave us authorization codes to download all three versions of Red Hat Enterprise Linux 3.0 for x86 architectures via the RHN (Red Hat Network)--a common distribution method used by Red Hat's customers. We downloaded the images, burned them to CDs and proceeded to install a network of RHEL servers and workstations in our Syracuse University Real-World Labs. This let us test various RHEL features and systems-management capabilities.
We installed RHEL AS (advanced server) on a multiprocessor server, ES (edge server) on a single-processor server and WS (workstation) on a desktop machine. AS was installed with logical volumes and software RAID configured, and with server-related software that would commonly be deployed on AS, including Apache and BIND.
ES was more basic, involving installing server processes, including Samba and NFS, on standard ext3 journaling file systems. Our workstation install was designed to mimic a Linux administrator's desktop and included software commonly used to build open-source software.
We tested all versions for interoperability among systems using the other versions. Examples of tests: We built open-source software on WS, used our AS box for DNS queries and delivered remote file services from our ES install.
Each install was connected to the RHN to grab all available updates at least once. Because the management module was enabled on our hosted RHN account, we populated and queried the database, verifying its functionality. We also searched the database by IP address and host name and looked for software installed on each via the Web tools provided with the hosted RHN management module.
Subsea cable alternatives can provide a level of comfort for those concerned about disruptions. Realistically, they will continue to play a small, but critical role in the short term.
Maintaining existing network infrastructures often incurs huge technical debt before newer technologies are adopted over time.
Amid ongoing regional uncertainties, telecom infrastructure in the Middle East has expand to include terrestrial low-latency network infrastructure, which offers resilience and agility in navigating political complexities without relying solely on undersea networks.
