AccessingRemoteBundleAccessing the remote bundle student documentationThis documentation covers the essential points that need to be known to access the remote bundle. Executive summaryStudents connect using telnet to www.cucat.org using teraterm. the password for each pod is pod1 pod2 and pod3, and the password for the remote power switch is power. selecting a pod limits the port range to a bundle of 1 router, 1 switch and 2 workstations.
router 2 provides clock signals to router 1 and 3 so is usually ISP in lab topology. /cn to connect to port n, control b to break back to the switch. Bundle explainedSerial switchThe serial switch has 16 rs-232C ports connected to various hardware in the remote bundle. Students telnet into www.cucat.org on port 23 to connect to this switch. You authenticate with one of the following passwords to obtain access to a subset of ports:
Once a connection is established a student can connect to the following ports:
To connect to a port simply key in /cn where n is the port number at the CMS prompt. press control-b to return to the serial switch. /s will show the status of the ports and which ones are in use by you or other students. /x will disconnect from the serial switch and close the telnet session. A telnet session has 15 minutes of inactivity before it times out. You can have up to 4 concurrent telnet sessions open to the serial switch at any one time. Please consider breaking back to the switch and switching between ports to conserve telnet sessions so your other students can utilize hardware you are not using. Talking to routers and switchesEach console port of the router or switch in question is linked into the serial switch, see list above. to connect to a specific networking device simply specify /cn where n is the port you wish to connect too. For example /c3 will connect to router 1. Once connected to the console port you can execute IOS commands. Please only set enable password to cisco and enable secret to class or you may lock out other students from the lab gear. To break back to the serial switch press control-b. Your IOS session will stay active for 5 minutes and then will then time out if not used. Linux workstationsConnecting to wks1-6 will provide you access to 6 Linux workstations. If the workstation is logged out hitting enter once connected will show a login prompt. If you hit enter and see a dollar or number prompt either you or a previous student left themselves logged into the box and the session remains open. as seen in the list above wks1 and wks2 are part of pod1, wks3 and wks4 are part of pod2 and so on. logging into a workstation requires you to use username cavi and password cavi each separated by pressing the enter key.
to obtain superuser privs execute bundle layoutThere are 3 pods that are separated into their own broadcast domains. Each pod contains 1 router, one switch and 2 workstations. the router and 2 workstations are wired into the switch on each pod. Each pod is isolated from the other pods and the only way to connect them is by using the routers which have serial cables connected to them as follows: Router 1: serial 0/0 connected to router 2 serial 0/0 Notice that the routers are wired in a loop however rarely are all interfaces up and operational at the same time. Configuring an ip address on the Linux workstationsEach Linux workstation has an ethernet interface called eth0. This is the ethernet card in the virtual machine. As workstations 1 and 2 share a physical machine both of the ethernet intrfaces are `bridged together in the virtual machine so it appears both virtual machines are on the same lan segment. To set ip address information on a work station log into it and become root, see further up in this document. You can then execute the following commands: |
