How to view and kill tasks or process running in a remote server

Windows has several built in command line utilities for performing various tasks, and two tools are useful for remotely viewing and killing tasks from command prompt.They are “Tasklist” and “Taskkill”. 

If you open an admin command prompt (Press Start, type cmd, press Ctrl+Shift+Enter) and type tasklist, it will give you a list of running processes on your computer. We can use same command with some modifications to view the task manager of remote computer in our network from our machine.

To view Task manager of remote computer use below format in cmd prompt [with admin privilege] from our machine

Tasklist /S remote system (name or IP address) /U username /P password

Example: Tasklist /S  192.168.1.1 /U sysnet /P P@ss@0rd

To kill process of remote computer use below format

Taskkill /S remote system /U username /P password /IM ProcessName

Example: Taskkill /S 192.168.1.1 /U sysnet /P P@ss@0rd /IM malware.exe

NOTE: You have to use IP address or Hostname of your server and your AD username and password instead of  192.168.1.100 , sysnet and P@ss@0rd respectively 

Note: To kill the process you want,Add the process name (including .exe) or the PID number along with the “/IM” argument as above example. If it works a SUCCESS message will show. If the process doesn’t get killed, try to add /F to the end of the line to force the process to be terminated.

Note: Some processes cannot be terminated such as those which are system critical or security software etc.

By adding a website to a specific zone, you can control the level of security used on that site. For example, if you have a list of websites that you visit and you completely trust those sites, add those sites to the Trusted zone.

How to ping multiple ip addresses from cmd prompt

If you are working as a  Network/System administrator you might come across situations to monitor network connectivity of multiple machines in your network at same time.Companies having large network may use Network Monitoring tools like PRTG Monitor .

As we all know, ping is one of the most useful network debugging tools used for verifying IP-level connectivity.Normally when we want to ping multiple IP addresses, we open command prompts and start pinging to each IP.

If the ping command gets a response, then the connection is good, and you can concentrate on other problems.If you are getting RTO's [Request time out] there is some connectivity problem in the network

If we have to monitor connectivity of multiple IP addresses we need to open each cmd prompt and need to ping all IPs.There are lot of free software which allow you to ping multiple IPs at same time.But many of the companies will not allow admins to install and use third party softwares to do that.In such cases we can use batch files to ping multiple IPs at same time.You can PING as many IPs with a single click.

How to make a Batch file to ping multiple IP addresses

- Open a notepad 
- Type

START "Google Primary DNS" ping 8.8.8.8 -t
START "Google Secondary DNS" ping 8.8.4.4 -t  

-Save it as Sysnet.cmd in your desktop .You can use as many IP address you want.All IP addresses are opened in seperate windows when you click on the Sysnet icon on your desktop

Instead of  "Google Primary DNS" you can use any Title you want.
Instead of "8.8.8.8" and "8.8.4.4" you can use any IP address you want.
Instead of "Sysnet.cmd" you can use any Name.cmd you want.

If you are interested in free software to ping multiple IPs at same time,You can try PingInfoView which is a small, very useful and free utility that allows you to easily ping multiple host names and IP addresses, and watch the result in one table.

Stop saving passwords in your browser

Do you save passwords in your browser?

If answer is yes,its time to stop that.Both Firefox and Google chrome are saving passwords in clear text format and anyone who have physical (or remote) access to your computer can see your passwords without any hacking skills.

Type chrome://settings/passwords in Google Chrome browser if you don’t believe me.You can see all your Passwords saved in Chrome, in plain-text format.There’s no master password, no security, not even a prompt that “these passwords are visible”.

In Firefox,  Options > Security tab > Saved passwords > 'show passwords' will display all your passwords and username in a neat list,that too in clear text format.Only added advantage is that you can (and right now should) set a master password, which you'll be asked for if you subsequently try to ,view those passwords. Chrome doesn't offer a master password
 
So if you are a person who leave your office / Personal laptop on your table without locking it,you are exposing all your passwords to a stranger.It will only take couple of seconds to gain access to all your important passwords for banking ,emails or social media.Anyone can do that.No need of any hacking skills

Try yourself
The simplest way to find out is to try it yourself. If you have Google Chrome or Mozilla Firefox installed, set yourself a challenge - how many passwords can you steal from your own computer in, say, one minute?

Solution

So how can you protect your passwords? You can delete them from Chrome. You can set a password on Firefox. More robustly, set up a screen lock on your computer and activate it before you walk away, no matter where you are. Don't let people use your user account - even people you regard as friends - if you're not watching them. You could also use software such as LastPass, which store your passwords and have their own master password. Some software  can also sync with mobile devices.
