In enterprise environment where service and network uptime is crucial in the daily operation, network managers requires uninterrupted monitoring tools to alert shift controllers.
Often tools are bought but are not fully used.
Among recommended tools are from Paessler (www.Paessler.com) , GFI and Opmanager.
Most elements depends on the snmp protocol to send the alarms and alert to the monitoring server.

Should you buy Checkpoint firewall?
I wouldn't be surprised to know that most of the telcos in Malaysia are running Checkpoint firewall in their data centres or even the UMTS network.
It's either the excellent marketing strategy made by the local partner/supplier/distributor or the proven capability of the firewall itself.
Firewalls are divided into 2 types, which is the software based and the 2nd would be the appliance.
In the early 90s, companies uses appliance firewall due to its effectiveness and faster thruput. Back then the firewall is just up to layer 3 filtering.
In todays environment, firewalls are evaluated based on their performance up to layer 7. That is how Checkpoint firewall differ with the rest of the firewalls in the market. Eventually most of the firewalls in the market today, claims that theirs are capable to run layer 7 fire walling.
Some of the points and advantages why I feel Checkpoint leading the market is;
1. ease of configuration via the smartdashboard
2. able to alert if there's duplication of rules or objects
3. ease of performing packet tracking based on current or past traffic.
4. sniffing made easier with fwmon
5. SPLAT(secure platform) friendly features
6. UMTS functionality for pdp context filtering
I've listed some that come across my mind and with the checkpoint community froup cpug in the net, the solution to most of the problems are easily made available.
The points above are based on my personal experience handling Cisco and Netscreen.
cheers..

Japanese humour from youtube
I found this clip funny.(just thought of sharing)Sometimes Japanese humor are creative, but most of the times they are a bit ridiculous.
Work! Work! work
It's been a while since my last post. Too many things happening with maid issue. I just can't believe how much Malaysian would spend to get good maid.
We'll, I've been changing maid 4 times in 2007.
It's a challenge of course, since your work, time and family is disturbed by some petty issues.
Other than maid, work of course is just another part of my daily task even when at home.
I have to live with it until I'm out of the around the clock kinda work. When no problem with the network, it's pretty ok. But when the fire started to build up, we are just the fighting the fire with fire. At this stage, experience came into play..'Only the know-how-&what-to do' people will survive the pressure and endurance.
Not necessary manuals are needed as they always say RTFM (read the f**kin manual)
I'm wondering how doctors deal with standby environment since they deal with human, and we(network support) deal with machines.
It's easy to blame the machine and kick them once we are sick and tired of their repeated problem, but can doctors do that?
Hmmm.. thank god I am no doctor. Me am cheap labor doing nite and day work :)
Just can't wait to be out of town vacation with family. (that of course if time permits)
