Why Ubuntu in VM cannot connect to the internet

By -
Usually, I got this problem when I start Ubuntu and I cannot connect to the internet.

So my fix is just pretty simple, though either might work in your end or not.

1. update your date
2. restart service on /etc/rc.d/networking

So in my case, how did I fix it is by

$ service ntp stop$ ntpdate 10.0.1.19$ service networking restart$ service ntp start
So where did I have this 10.0.1.19? This is my other VM also, act as a server which interacts through the ntp socket and updates from the 10.0.1.19 server's time. If you don't have other VM, I'm not sure with this, just try to update your date to the recent date you have.

Afterwads, just run

$ /sbin/dhclient eth0

and hope everything will work into your end.

Converting sectors into MB - Useful in understanding the sectors in iostat in Linux

By -
Supposed you have a sector with 512 Bytes equivalent, then the formula will be just below 1 sect. 1024 Bytes 1024 KB --------- x ---------- x --------- = 2048 sect./ MB 512 Bytes 1 KB 1 MB i.e. if a sector has a 512 Bytes, commonly in a hard disk, so which means that a 1024 Bytes == 2 sector of a KiloByte. So if 2 sector is equivalent to a KiloByte (1024 Bytes), if you do the math, 2 ** 1024 / 512.0 = 2048. This is useful only understanding the iostat process in Linux.

What is Disk Contention?

By -
Okay, so let me take a note about this meaning... Disk contention occurs when multiple processes try to access the same disk simultaneously. Most disks have limits on both the number of accesses (I/O operations each second) and the amount of data they can transfer each second (I/O data rate, or  throughput ). When these limits are reached, processes must wait to access the disk. It's a situation occurring when multiple processes try to access the same disk(s) and the requests outrun the response times of the drive(s). This happens because most disks are restricted in the amount of data they can transfer and the number of accesses (I/O operations) they can handle each second. Disk contention became a more prominent problem when CPU speeds dramatically increased over the past 15 years, putting even greater demands on disk-based data storage and causing the modern data centers’ most significant operational constraint.
