Nick Urbanik Copyright Conditions: GNU FDL (see http://www.gnu.org/licenses/fdl.html) Department of Information and Communications Technology SNM — Subject Summary— ver. 1.0 – p. 1/14 Main Topics in this Subject Perl SNMP Network Troubleshooting Network Design DHCP and DNS systems LDAP directories and querying them Routing, Route Summarisation SNM — Subject Summary— ver. 1.0 – p. 2/14 Perl We covered the basics of the language Refer to the Perl Summary that I wrote You did two assignments Revise your work in both of them I will provide a copy of the booklet Perl Reference Quide in the exam (no need to bring your own copy) Please return the booklet in the exam Please do not write in it or mark it We want to use them again next year There is one question in the exam on this topic SNM — Subject Summary— ver. 1.0 – p. 3/14 SNMP There are two sets of notes on this topic; one (short set) from Albert on the ISO network management model, one (long set) on the practicalities of SNMP You have configured an SNMP agent in the laboratory In the lectures you also studied SNMP version 3 If I had more time, I would have made some laboratory exercises on this topic You had a test on this topic. I suggest that you revise this. There is one question on this topic in the exam SNM — Subject Summary— ver. 1.0 – p. 4/14 Network Troubleshooting — 1 This is a new topic; there are no previouos exam questions on this topic. I focussed on the use of Ethereal and tcpdump for collecting information about network problems However, Ethereal screen dumps don’t fit well into an exam paper I wrote additional notes on using tcpdump with DHCP So you may use your judgement as to which Ethernet packet sniffing tool I refer to in the exam. SNM — Subject Summary— ver. 1.0 – p. 5/14 Network Troubleshooting — 2 We also examined many uses of such important and commonly available basic tools as traceroute (or tracert) and ping Do not waste time memorising any lengthy formulas; if they are required, they will appear in an appendix to the exam. We covered many topics in this area, including troubleshooting a switched network Altogether, there is one question directly on this area, and half a question that is at least partly on this area SNM — Subject Summary— ver. 1.0 – p. 6/14 DHCP and DNS Management Systems We covered the basics of DHCP operation including normal operation, and problems that can occur in DHCP operation We also studied two schemes for automating DHCP and DNS management One scheme introduced at this Institute, in the Computer Centre and our Department, One fully automated registration scheme involving a web registration application to which new users are automatically directed There is half a question directly on these topics, and another half question that includes these topics SNM — Subject Summary— ver. 1.0 – p. 7/14 LDAP directories and querying them — 1 We covered a number of aspects of LDAP directories, and I provided a laboratory exercise in setting up network accounts on a directory server, But due to insufficient laboratory time, we did not work through this in the classroom That will not be in the exam However, we covered a few topics in authentication and authorisation both in the lectures and in the laboratory SNM — Subject Summary— ver. 1.0 – p. 8/14 LDAP directories and querying them — 2 I have already told you that: an appendix to the exam paper from RFC 2254 describes the grammar for LDAP Another appendix to the exam paper from RFC 2255 describes the grammar for LDAP URLs. There is one question on this topic in the exam. SNM — Subject Summary— ver. 1.0 – p. 9/14 Routing, Route Summarisation Due to the SARS epidemic, my planned coverage of this area has been reduced, mainly to covering: route summarisation and address block allocation and design. In particular, we have not covered the same areas of switching as in the previous year I suggest that you be guided by the tutorial exercises we do in this area. There is half a question on this topic in the exam. SNM — Subject Summary— ver. 1.0 – p. 10/14 Format of the Exam (2002–2003) There are five questions There are no options—do all five questions That’s good—no need to waste time deciding which one to leave out! SNM — Subject Summary— ver. 1.0 – p. 11/14 Advice for the Exam Budget your time wisely in the exam: Spend a few minutes to plan your time Divide remaining time by five Do not spend more than this time on any one question until you have answered five questions fully Show your working A wrong answer with no working gets zero marks A wrong answer with some working that is on the right track gets some marks SNM — Subject Summary— ver. 1.0 – p. 12/14 Summary of Topics in Exam Topic Number of Questions: directly, partly 1 1 1, 1/2 1/ , 1/ 2 2 Perl SNMP Network Troubleshooting Network Design: DHCP and DNS systems LDAP directories and querying them Routing, Route Summarisation 1 1/ 2 SNM — Subject Summary— ver. 1.0 – p. 13/14 Watch the Subject Web Site I will begin writing solutions to past exam papers, the test, laboratory exercises and workshops, and post them on our subject web site Watch the web site for announcements: I will write and post solutions to problems as soon as I can. I will make a new icon to highlight changes on the site, including solutions to problems as I write them. SNM — Subject Summary— ver. 1.0 – p. 14/14
