I just thought about this topic which we had brainstormed some time back, say a network is running on DHCP which serves ip address 10.205.205.0/24, now how do I introduce fail over into the system ? Put in 2 DHCP servers with the same range ? Well, that would be nice, ... Continue Reading

One nice piece of article, by that I mean short and sweet or to the point about PERT. Nicely written by Tom at Techrepublic. By the way, if you wanna know more about such stuff Tech Republic is a good place to have its place in your bookmarks. Regardless ... Continue Reading

Another last working day for me, after being employed at Juniper Networks India finally I decided to pursue something more challenging. The way I visualize things is what was told to me today  :-) "It is difficult to keep me challenged and interested". I believe it is much more ... Continue Reading

Since the last post was on unusual tcp connection tear down, it is also important to understand different actions a typical firewalls can take; Drop -> The packet is dropped and never informed about the sender. Reset -> A RST is sent to the sender to let him know ... Continue Reading

If you're a video/photo junkie, you'd have always played with resizing partitions, extend it/shrink it would've been a regular practice for the reason that captured videos are pretty big in size until it gets compressed to another format. Now, I like the part being included in Vista (no more partition ... Continue Reading

From Vista onwards the flash.ocx is no more shipped I guess, so any standalone application that has to do with flash wouldn't work unless the ocx is installed. Unfortunately, Adobe seems to be providing only browser based plugins! So I downloaded flash player from here (standalone version) I installed it ... Continue Reading

May be not often but still you may need to configure static nat for some purpose like this; Say; You want to map; 1.1.1.1 -> 10.20.30.40 2.2.2.2 -> 10.20.30.40 On a PIX/ASA firewall this would not be allowed to be configured, so how do you overcome this restriction ? ... Continue Reading
