How to delete more than 50 emails in Gmail in one shot ? - Cleanup Gmail

   Gmail regular-user account provides maximum 15 GB storage, by default.  It is usually not sufficient for this information explosive age.  We may need to bulk delete multiple old/spam emails from a sender in one shot to quickly save storage.

   Gmail provides a way to create a new Filter to find all these emails from a sender and then delete it.  Unfortunately, creating a new filter rule everytime may be an overhead and here I show how we can find all these emails and delete it without creating rules.

    For example, Here, I am going to delete all the emails I received from "(noreply+feedproxy@google.com)".

1.) Find all the emails by searching them in the search box, from:(noreply+feedproxy@google.com).

(OR) 

Select any one message, and then choose 'More :', choose 'Filter messages like these'.

2.) Now 'Select all' message option now, and then choose 'Select all conversations that match this search'.

3.) Now all the conversations selected. Simply press 'Delete' button. 

That's all !!!

How to move OneNote Note book to OneDrive ?

How to move OneNote Note book to OneDrive ?

I am not able to follow the documentation here, as it asks me to move individual OneNote Sections.

https://support.microsoft.com/en-us/office/how-to-move-my-local-notebooks-to-onedrive-or-sharepoint-7343c424-cdee-4bbf-9245-312549e81fc0

To move a notebook using OneNote 2010:

Open the notebook that you want to move, and then click File > Info > Share on Web or Network.

Follow the on-screen instructions to finish moving your notebook to OneDrive or SharePoint.

Instead I move with one step like this:

1. Let me move 'My Notebook' from local drive to cloud (OneDrive).

2. Go to File -> Info. And see 'Settings' of the notebook.

3. Choose Properties.

4.  Choose 'Change Location' and choose OneDrive Location. That's all.

Backup files in MicroSoft OneDrive without loosing existing folder structure

Problem:

To backup files/folders in OneDrive, you need to move the files/folders under "OneDrive" cloud folder.
This can be painful if you already have applications/links referring to this source folder.
Moving your folder to 'OneDrive' cloud folder is disruptive here.
Alas! Those applications will break, and it is not easy to fix the links to new locations one by one.

Solution:

1. Move the files/folders to 'OneDrive' cloud folder as you do normally.
2. Create a link to the new folder under 'OneDrive' from previous location using mklink' utility.  This is explained here: How to take advantage of symbolic links in Windows 10

Example:
a.) Win + R, "CMD", Ctrl + Shift + Enter to enter Administrator mode.
b.) C:\Users\Saravanan\Desktop>  mklink /D C:\Users\Saravanan\Desktop\Step_One "C:\Users\Saravanan\OneDrive - My corportation\Step_One"

Here, I moved my "Step_One" folder from Desktop to OneDrive, and then I created a link in Desktop to new location of this folder under OneDrive.

This will make transparent redirect of file pointers to new locations for your applications, and make your OneDrive transition easy :-)

Enabling debugging in OpenSSH client and server

Assumptions :
     1.) Linux Debian based configuration files are used. (OpenSSH_5.5p1 Debian-6+squeeze5)

SSH Server :

1.) Update the /etc/init.d/ssh file to include debug option.

#diff /etc/init.d/ssh /etc/init.d/ssh.orig

30d29

< SSHD_OPTS="$SSHD_OPTS -ddd"

#

2.) Start the ssh services in the server.

# service ssh --full-restart

sshd(8) - Linux man page 

Synopsis

sshd [-46DdeiqTt] [-b bits] [-C connection_spec] [-f config_file] [-g login_grace_time] [-h host_key_file] [-k key_gen_time] [-o option] [-p port] [-u len]

 

sshd (OpenSSH Daemon) is the daemon program for ssh(1). Together these programs replace rlogin(1) and rsh(1), and provide secure encrypted communications between two untrusted hosts over an insecure network.

sshd listens for connections from clients. It is normally started at boot from /etc/rc. It forks a new daemon for each incoming connection. The forked daemons handle key exchange, encryption, authentication, command execution, and data exchange.

-d'

Debug mode. The server sends verbose debug output to the system log, and does not put itself in the background. The server also will not fork and will only process one connection. This option is only intended for debugging for the server. Multiple -d options increase the debugging level. Maximum is 3.
