Mac

Where should I put movie files at video production.

Save and edit your files in the home directory of Mac environment. It is 4TB and can be accessed at high speed.

However, please delete it as soon as you finish your editing work, as it is shared with other users.

After you finish your work, please be sure to back up your work by copying it to "CNS_HOMEDIR (CNS home directory)", "your own external HDD/SSD", or "online storage", etc.

The procedure to add and remove Add-on for Firefox

Install Add-on

1. Click "Tools" => "Add-ons" on the Menu bar.
2. Search Add-on which you want and click Install. The download will be started.
3. Click "Restart now"
4. Please confirm Add-on has been installed on the "Tools" => "Add-ons" => "My Add-ons"

Remove Add-on

1. Click "Remove" button on the "My Add-ons" view.
2. Search Add-on which you want and click Install. The download will be started.
3. Click "Restart now"

An administrator password is required to create/copy files to an external hard disk drive.

Choose the one from two alternatives below.

1. Connect the external hard disk to your PC, and open a terminal.app, and then type "chmod o+x /Volumes/{A name of an external hard disk}".
2. Use an external hard disk which is formatted to exFAT file format.

Windows

There is nothing.

Shared computing server

かな漢字変換ができない (Japanese)

• jserverが起動していない
  emacs上でM-x set-wnn7-host-nameと打つと、wnnhostを指定できます。nls00, nls01のホストでjserverが起動しているので、どちらかを指定してみてください。
• Wnnの頻度ファイルが壊れている
  

  % cd Wnn8; mv hindo hindo.old
  

  のように、hindoを待避してemacsを再起動して漢字変換すると、(y or n)と聞いてくるので、これに対してすべてyと答えると新しく頻度情報を作成し、正常に変換できるようになります。 頻度ファイルは ccz00,各Mac 環境で作成可能です。現在、ccx01 では作成できません。

emacs,ls commands not found

• Maybe you lost CNS configuration file. Please execute the following procedure.

  cd [ENTER]
  > echo "source /usr/local/lib/setup/.cshrc" > .cshrc [ENTER]
  > source .cshrc
  %
  

  This problem is solved when "%" appear.

Can not ssh remote login to ccz00

• WARNING similar to the following is display when ssh remote login to ccz00.

• This is because the fingerprint has changed by the Replacement of shared computing server（Sep. 17）.
• Please delete the old fingerprint from ~/.ssh/known_hosts by running the ssh-keygen command.
  

  % ssh-keygen -R ccz00.sfc.keio.ac.jp
  /home/z00000tk/.ssh/known_hosts updated.

• Please delete the ~/.ssh/known_hosts file if you still can not connect.
• Again, fingerprint is displayed when you ssh remote login to ccz00. パブリックサーバ公開鍵fingerprint Please make sure that it matches the fingerprint that has been described. Please run it by entering the "yes".
