Using "clue" (LS.Berkeley.EDU)

This page is being maintained for archival purposes only. The clue server was retired in 2011.

The main L&S web server, LS.Berkeley.EDU, is nicknamed "clue." It provides web service to L&S and related departments. This article describes how to connect to and use the server.

Software for connecting

All connections to clue must be secure, in accordance with the campus Minimum Security Standards. There are a number of secure file transfer clients, and recent versions of most web editing software (such as Dreamweaver MX or later) also include secure file transfer functions.

File transfer programs

• Secure Fetch (free download from Fetch Softworks)
• WinSCP (free download)
• Host Explorer (free download for Windows from software-central.berkeley.edu)
• Fugu (free download for Mac from University of Michigan)

Web editors with secure FTP functionality

• Adobe Dreamweaver (available for discounted purchase from SHI)
• BBEdit (available for purchase for Mac from Bare Bones Software)

Unix shell tools (telnet-like)

Using your account

File locations

• Department web pages are located in the /ls/htdocs/dept/<department_name> directory. If you create a file named index.html (or index.htm, or index.php) in that directory, it will by default become your "home" page.
• You can create a directory called public_html in your home directory, and place CGI scripts there (with a .cgi or .pl file extension). Or, mail sysadmin@LS.Berkeley.EDU to request that your CGI be installed in the system cgi-bin directory. Generally, we recommend that CGIs which will be in ongoing production on your live web site be placed in the cgi-bin directory; you can use public_html for test purposes.
• If your department has a virtual host name (such as english.berkeley.edu), your web logs can be found in the /web/<department_name>/logs directory; otherwise, they are in /web/main/logs.

Web statistics

• If your department has a virtual host name, historical statistics will be automatically generated monthly and saved in http://<host_name>/stats.
• Ad-hoc stat reports can be run from our Analog web form.

Quotas

Quotas are set on a per-account basis (default 100MB). You can check your account's current usage with the quota -v command.

Permissions

Most departments have more than one person working on web pages. It is usually beneficial to make sure that all your pages are writable by your departmental group. Some clients (such as Dreamweaver) allow you to set group-write permissions on uploaded files, or, you can use the Unix command line to change permissions. (The Unix command "chmod g+w <filename>" will set a file or directory to be group-writable. If you add the command "umask 002" to your .login file, all files you create will be group-writable.
