      In my opinion you probably don't want to give write access to the account
      that runs the web server. Maybe give write access to a few required files
      here and there, but otherwise read-only access. Again, that is just my
      own personal practice. Almost all my files are set to root:lighttpd with
      the mode on the files set to 644 and directories set to 755.

      If you still want to give write access to your 'www' account, you might
      consider installing RSSH (www.pizzashack.org/rssh/) for the shell. In
      this way you can still prevent the 'www' acount from having an interactive
      shell, but you can still SCP/SFTP files to your server. Plus it has all
      sorts of configuration settings for configuring the umask and the mode on

      I personally don't find it all that inconvenient to upload files using a
      normal user account, and using 'sudo' to move my files to the configured
      web folders and again using 'sudo' to set the permissions. It is not like
      you are going to be hosting hundreds of sites on an NSLU2.

      You might also google the chmod command and consider using the sticky bit
      on directories. I have done this in a few cases on folders outside of the
      web directories (like my Music directories), so that I can copy files
      using SMB as any configured SAMBA user and still have the group
      permissions set correctly so that the web server account can read the

      If you are just looking for convenience, just do as another user suggested
      and just set your desired shell by editing the /etc/passwd file. Just
      remember in almost every instance secure does not mean convenient.
