I would say that most media problems arise when their is clnfoict of race, gender, nationalism, idealogy, ethnicity, or political system. These are the things that are exposed within the media, and they are usually entwined with eachother. Therefore, I would say that the best approach to understanding how media impacts society is to take the holistic approach, and not through classical mechanics. Through psychology, sociology, ethics, and an aware/observant approach to study the media, the problem solving can come about once both parties in clnfoict stop pointing the finger and come to a peaceful/moral solution. Individual political and economic gain must be left out of the matter as well. There needs to be a mutual feeling on both sides of the front that we are all connected and a part of the same environment, which hopefully will lead to more self-less acts and help promote constructive communication. All of the religions of the world should come together and discuss similar core beliefs and values, and should start working with eachother more to promote the things all of us have in common, which will help support a positive media system. This may not be enough, so the change in the educational system will be very important in contributing to global positive change in communcations. Although literacy in school is important, the education system, from the begining needs to hold creativity as one of its most important values in guiding and supporting students. My view seems to follow the WE section of the 4 square chart, where there will be a positive collective world view, while still preserving cultural diversity through mutual respect and reverence towards others who are different than us.

SFTP using SSH2: Key based authentication

There are three mechanisms for use of the FileZilla client with SSH2 keys.

  1. In the profile settings in the Site Manager of the FileZilla client. If the SFTP Protocol is specified, it is possible to specify the Logon Type as "Key File" and specify the location of the private key file (in putty's .ppk or openssh's .pem format) The user is prompted for the key file's password if necessary, which may optionally be cached by Filezilla until it is next shut down.
  2. In the Edit - Settings menu of the FileZilla client, you can [Add key file...] under Connection - SFTP, and FileZilla can then use the public key authentication in the site manager with the 'Interactive' Logontype on connection. Note: Importing a site's public key is not supported.
  3. (Windows only) Using the excellent PuTTY tools. To allow the use of RSA / DSA key files with Filezilla, you'll need to download two more tools from PuTTY: Pageant and (assuming your key file isn't already in PPK format) PuTTYgen.

generate ssh key

Filezilla can use existing ssh key, but cannot generate ssh key itself. you can generate ssh key with putty or openssh. (now openssh is built-in in windows.)

  • putty: use GUI program PuTTYgen to generate ssh key.
  • openssh: open cmd.exe or powershell, type command ssh-keygen -t rsa -b 2048 -f my-ssh-key will generate private key my-ssh-key and public key my-ssh-key.pub .

after generate new key, you need to add the public key to the file ~/.ssh/authorized_keys , or concact the system admin, then you can login with private key.

Using ssh key with putty's ssh agent

If your key file is already in PuTTY's PPK format you can skip this paragraph. However if your key is in OpenSSH format, you first need to convert it to PuTTY's PPK format. To do this, launch PuTTYgen and from the "Conversions" menu, select the "Import key" option. Select your key and follow the prompts to enter your pass phrase. Save your private key.

Now run Pageant. In your system tray, you'll see the Pageant icon appear. Right-click the icon and select "Add Key" and select your private key (PPK) file. Follow the prompt to enter your pass phrase and you're done.

Now simply launch FileZilla and connect to your server using SFTP using SSH2 with a username and an empty password. Don't forget to close pageant when you're done.

This also works with the portable versions of FileZilla and PuTTY tools.

Alternative Method

FileZilla supports the standard SSH agents. If your SSH agent is running, the SSH_AUTH_SOCK environment variable should be set. (Note, the "Normal" logon type should be set for the server in order to use the SSH agent socket.)

On a Mac

If for some reason you are not using ssh-agent and on a Mac, don't worry about ssh key conversion. Just import your key via Settings and then use Normal mode in your site connection definition. The imported key will get used.

The following instructions assume you have a working SSH configuration which allows you to ssh to the same host without a password. They are adapted from a thread on superuser.com and summarized here so you don't have to search through a lot of dead ends:

  1. In FileZilla->Settings.. select Connection->SFTP
  2. Press the Add key file... button
  3. Press Command-Shift-G to bring up a path selection window and type "~/.ssh"
  4. Select the "id_rsa" key file and click Open (this imports the key)
  5. Click OK to close the Settings dialog
  6. Open File->Site Manager...
  7. Select the site with which you want to use the key
  8. Choose Protocol "SFTP" and select Logon Type "Normal". Don't worry about a password if you key file doesn't have a password
  9. Click Connect and you'll see your files
