IP alias or virtual ip address in Ubuntu Linux

2011-12-01T00:03:00.001+05:30

Introduction Sometimes same physical ethernet device may need to impersonate to the outside world as n devices or n ip addresses. This maybe helpful in hosting n different servers without a need to goto n physical devices. Here comes the idea of virtual alias Creating virtual ip or ip alias (this works in ubuntu) Say my ipaddress is 192.168.2.2 and my ethernet device is eth0 then to

Streaming Full HD movies to PS3 with existing G router and PS3 Media Server

2010-08-04T10:24:00.001+05:30

Does streaming a HD movie to a PS3 or some media player require N router? Will Full HD streaming work on an existing G router? Does streaming require only 100 Mbps ethernet cables or 1000 Mbps Gigabit ethernet cables ? This article tries better to answer that and a probable solution (which worked for my friend and I know how happy he is!) First I will try to present a math of HD movie in PS3.

2010-04-14T09:53:00.001+05:30

Today morning I tried live CD of Fedora 13 Beta and I felt it is very very fast. I was thinking why my installed debian is not so fast as Fedora 13 though I have a kernel compiled for core2 but with 300 HZ frequency. To check if debian also will get such feel of speed, I recompiled my kernel with 1000 HZ frequency. Now it feels as fast as Fedora, thanks Fedora!! To tell, it feels like debian

Reclaiming the reserved space from a big ext3/ext4 partition

2010-04-06T08:51:00.001+05:30

When we have a 500 GB or 1 TB partition and it is formatted in ext3 or ext4, filesystem reserves 5 percent space by default This is not a problem when the partition size is small, but 5 percent of a 500 GB partition is 25 GB and 5 percent of 1 TB is 50 GB Fortunately we can reclaim the reserved space of an ext3/ext4 partition using tune2fs We need to have root privileges to configure reserved

Windows or Linux has a long way to go
