CrystalDiskMark – disk benchmark software

Neat simple tool that lets you check your disk performance from ‘Crystal Dew World‘.
There are couple of other tools on the site – not tried them though. All distributed under modified BSD license.

CrystalDiskMark – http://crystalmark.info/software/CrystalDiskMark/index-e.html
(Note: install also prompts to install PC Matic – PC Pitstop free scan which is another 3rd party program to test overall performance and is not from CrystalDiskMark)

List open ports – netstat

netstat can be used to list all open ports on a machine Linux

$ netstat -an | grep -i listen
Command options will be different in diff version of linux

Windows

> netstat -a | find /i "listening"
> netstat -b     //will show the process names
> netstat -?

Powershell with netstat, netsh

Powershell also makes it easy to use and process the output from netstat, netsh or any other commands.

C:\> $n = netstat
C:\> $n | select-string "listening"

(See links below for related articles. Powershell allows getting net statistics via cmdlets like Get-NetIPAddress, the .net classes in System.Net.Networkinformation etc.)

All I want to do is mount a windows shared folder on my ubuntu box and access the files; I am not worried about mounting during boot up and not sharing any files from ubuntu.

  1. install smbfs
    1. $sudo apt-get install smbfs
  2. use ‘mount’ to mount the file share
    1. for mount you need to create a local folder that will be the mount point for example create a folder test under /media
    2. then mount the share using
      1. $sudo mount -t smbfs -o username=myusername //192.168.0.10/sharename /media/test
      2. myusername – is a valid username on the windows machine
      3. the ip address is the ip of the windows machine
      4. sharename is the name given to the share on the windows machine
      5. This will prompt you for the passwor d- the password for myusername on the windows machine
      6. on successful password you will be able to see the contents of the sharedfolder under /media/test
      7. Note: if you this is the first time you are using sudo in this shell session or if sudo has timed out there will be two password prompts first for the sudo next for the share mount. you could avoid this by doing $sudo -v before doing the sudo mount
  3. to umount
    1. $sudo umount /media/test
