100111001.100110010.11100111.00010010 Roughly about 5 subnets so have to use 3 subnetbits, subnet masks becomes 11111111.11111111.10100000.00000000 wahahahaha I don't even know if I'm right.

Quick review for self

5 steps for sub netting for dummies
1. how many netID?
2. how many host (hostID) the network have to support?
3. define subnet mask that will support #1 and #2
4. define the subnetID to be used for the logically partitioned network
5. give the nodes in the network their hostID

SNMP - Simple Network Management Protocol
Goals - integrating all functions, centralised management, low cost for developer, manages device remotely, produce network analysis reports, simple

Network Management Concepts
- Application Management
- System Management
- Transmission Management (Performance, Fault Security, Configuration, Accounting)

What does a Network Management System should have/do?
- GUI, network map
- Trend analysis, network reports
- Logging (Server status, user logins, events)
- Virus protections, Alerts, Alarms, intruder detection
- Hardware monitoring, automatic log backup
- Examples, IBM Tivoli, NetView, HP OpenView

LDAP - Lightweight Directory Access Protocol, A protocol to access directory services over a network.

LPAD securities benefits
- authentication
- authorisation
- encryption
- SSL

LDAP vulnerabilities
- man in the middle
- DoS attacks
- data confidentiality

Firewalls - often consists of either one or both packet filter and proxy server
Types of firewall architecture
- packet filtering
- dual homed host
- screened host
- screened subnet

.... Hais...ok la...today's entry is more for me. Need to recap ma. Anyways, I almost cried reading this today. Very nice story. Funny yet sad. A small snippet below.
