======================================== WT111, WT114, WT115 hardware information ======================================== Advanced Technology Centre Networking Laboratory (WT111, WT114, WT115) Instructor Guide Prepared by: Murray Bell Professor Computer Studies Office: Rm WT313.2 Tel: 727-4723 x5986 E-Mail: bellm@algonquincollege.com ATC Networking Laboratory Guide The following describes the conventions and networking setup for the Networking and Real-Time labs (T111, T114 and T115) in the Algonquin Advanced Technology Centre (ATC). Network Lab Computer Configuration: Each lab contains 24 student computers and one instructor computer. All computers have an identical hardware configuration: Pentium III 866Mhz Processor 256 MB RAM 1.44 MB 3.5" Floppy Drive Bootable 52X IDE CD-ROM Drive (Master device on IDE Secondary Channel) ATI Rage Fury Pro/Xpert 2000 Pro Video Adapter Creative Labs PCI128 Sound Card (front-mounted headphone jack; no speakers) Receptacle for RH-06F/RH-20 Caddy Hard Drive (connected to Primary IDE Channel) As these computers have no internal hard drive, the user must supply their own in a compatible caddy tray (RH-06F, RH-10 or RH-20). The computer BIOS is password protected to deter configuration changes by students. Each lab computer also contains two 10/100 Mbps Ethernet Network Interface Cards (NICs): NIC Type DOS Resource Settings Novell ODI Driver Connected To 3Com 3C905B I/O Port = A000 3C90X.COM Blue Network (Lower - Slot 5) Int (IRQ) = 11 Realtek RTL8139 I/O Port = A400 RTSODI.COM Red Network (Upper - Slot 3) Int (IRQ) = 9 Network Lab Physical Network Configuration: Each lab contains 3 sets of Cat 5e100 Mbps UTP network cabling (visible in the floor): the Blue, Red and Green networks. Each computer bench has 3 colour coded network jacks for connecting the 2 NICs in each lab computer to any of the 3 networks. Normally, the 3Com 3C905B NIC is connected to the Blue network, and the Realtek RTL8139 NIC is connected to the Red network. The Blue, Red and Green network cabling is terminated at colour coded patch panels mounted in the lab equipment rack. The Blue network is connected by short patch cables from the Blue patch panel to a Cisco 32 port 100 Mbps Ethernet Hub. The Red and Green patch panels are available to connect lab computers to other network equipment in the rack as required. In WT114/115, the Green network is used to connect the COM1 serial port of the lab PCs to the Green patch panel. This permits convenient console access to networking equipment in the lab racks The lab network printer and certain servers located in the WT114a server room are also connected to the Blue network via the Cisco 32 port 100 Mbps Ethernet Hub. For the printer and the connections to the server room, the network cabling is colour coded White, and terminated at the White patch panels in the equipment rack. Network Lab Logical Network Configuration: The Blue Network in each lab is configured as a Class C private TCP/IP network as follows: Lab Room Network Address Default Gateway DNS Server WT115 192.168.1.0/24 192.168.1.250 192.168.1.245 WT114 192.168.2.0/24 192.168.2.250 192.168.2.245 WT111 192.168.3.0/24 192.168.3.250 192.168.3.245 The Class C network address space for each lab is allocated as follows (x=1, 2 or 3): a. 192.168.x.1 to 192.168.x.50 - DHCP address pool - lease time 3 hours; b. 192.168.x.51 to 192.168.x.200 - reserved for student static IP addresses; c. 192.168.x.201 to 192.168.x.254 - reserved for lab servers, printers, routers, etc. The lab servers located in the WT114a Server Room are: Server Name Server OS Main IP Address Services W2KS Windows 2000 Server 192.168.x.245 DHCP, DNS NW6 Novell NetWare 6 192.168.x.250 NAT Router Linux Red Hat Linux 7.2 192.168.x.235 VirtualLab Windows 2000 Server 192.168.x.240 Terminal Server The Windows 2000 server, W2KS, is the first and only domain controller for the Active Directory Forest Root Domain, AlgonquinATC.Com. W2KS also hosts the lab DHCP and DNS servers. The DNS server is authoritative for the lab DNS domain, which is AlgonquinATC.Com. The DHCP and DNS servers are configured to support Dynamic DNS; hence lab computers may be accessed by their DNS host name. The lab DNS server is configured as a forwarder to the Algonquin ITS DNS servers; hence you may point to the lab DNS server to resolve the internal lab computer names in AlgonquinATC.Com as well as external Algonquin intranet and public Internet names. The NetWare 6 server, NW6, is installed in the NDS eDirectory tree ALGONQUIN. NW6 acts as the Default Gateway for the lab networks. It is configured as a Network Address Translation (NAT) Router and connects the lab networks to the Algonquin intranet maintained by ITS and, via the Algonquin intranet, through the Algonquin firewall to the public Internet. The NetWare 6 server also contains a public repository of software (e.g. Windows 98SE, Windows 2000, NetWare 5, etc.) which can be accessed from any computer in the labs using a DOS network boot disk (floppy or bootable CD-ROM) or via any desktop OS. The software is found at NW6\VOL1:SOFTWARE using the account CN=Guest.OU=ATC.O=Algonquin with a password of password. NetWare 6 has a new feature called Native File Access Pak (NFAP) which permits access to its file system from Windows 9X/2000/XP, UNIX/Linux or Macintosh using each system's native network client (i.e. a Novell network client is not required). In the case of access from Windows, the NFAP server name is NW6-CIFS (and is accessible using the account Guest with password = password). The network printers in the labs have been assigned names and IP addresses as follows: Lex1855 (T115) 192.168.1.249 (Lex1855.AlgonquinATC.Com) LexT612-1 (T114) 192.168.2.249 (LexT612-1.AlgonquinATC.Com) LexT612-2 (T111) 192.168.3.249 (LexT612-2.AlgonquinATC.Com) Lab network printers may be accessed as a standard LPR/LPD TCP/IP printer.
