Background
|
|
|
Many networks are a hybrid of different types of
networking operating systems. Napier University has three main
networking operating systems: Microsoft Windows NT (NetBEUI and
TCP/IP), Novell NetWare NDS (IPX/SPX) and UNIX (TCP/IP). These
networks have to be carefully designed so that users have optimal
access.
|
|
The connection from the desktop connection can be
traced by determining how servers are mounted onto the local workstation.
Typically, at Napier, this is done either with NTFS, NFS or NDS
(see Figure 1 for the current setup). These connections can be
viewed by examining the properties of mounted drives.
For the TCP/IP networks, software tools for TCP/IP can
be used to determine how networks interconnect and the services that
run on them. IP implements the network layer of the OSI model, and is
responsible for network addressing. It is possible using software programs,
such as ping and traceroute, to determine how networks interconnect.
The results from these programs can give information on the subnets
within the network, and how they interconnect. TCP implements the transport
layer of the OSI model and is responsible for setting up sockets and
ports. Servers run programs which listen for connections to specific
ports, such as 21 (FTP), 23 (TELNET) and 80 (HTTP). It is possible to
determine the services that run on a network by performing a port scan
on all the hosts on a network segment.

Coursework Aims
|
|
The aims of the assignment are:
|
|
To investigate the logical infrastructure of the network in
the Craiglockhart Campus.
|
|
|
To investigate the location of TCP/IP servers and the basic
services that they provide.
|
|
|
To contrast the methods used in building a large corporate
network, especially in relation to NDS, UNIX and NT, and how
this relates to the network operating system infrastructure
within Napier.
|
|
|
To critically appraise the network operating system provision
at Napier, especially related to the provision of services to
the desktop.
|
|
|
Coursework Brief
|
|
Using software tools, such as a port scanning program,
ping, traceroute, and so on, determine the network infrastructure of
the network within Craiglockhart and the TCP/IP services that servers
listen for Investigation may involve:
|
|
Logical connection of subnets and routers within the Craiglockhart
Campus
|
|
|
Logical location of TCP/IP servers, and the subnets that they
are connected to
|
|
|
Determination of the services that the servers respond to,
such as TELNET, FTP, DNS, SMTP, and so on.
|
|
|
To any determine weaknesses in the current provision
|
|
|
Investigate the desktop connections and the services which
they provide. Also how NDS,
UNIX and NT are used to provide services.
|
|
Resources
|
|
|
|
TCP/IP programs, such as ping, telnet, and so on
|
|
|
Port scanning program
|
|
|
Windows 95/NT network utilities (such as NetLab 1.4, Wsock,
Ping Pro, and so on).
|
|
|
PC/Network connection.
|
|
Assessment Criteria
|
|
A report should be submitted which will normally have
less than 30 pages of typed A4 (quality is more important
than quantity). This report should assess the relative merits for
the implementation of networking operating systems over a corporate
network and also investigate the infrastructure of the network and servers
within the Craiglockhart Campus. The practical investigations should
give some in-sight to the strengths and weaknesses of the network operating
system provision at Napier.
