Welcome to CMB!

(Ruhl Group Mail / Web Server)



General Info

This Debian GNU/Linux machine is part of the Ruhl group, and acts as the primary mail/web server. If you are a group member and have any questions about how this machine is set up please contact Ted Kisner. All mail is stored in your home directory in ~/Maildir (not in /var/spool/mail) in the "maildir" format. This format eliminates corrupted mailbox files that may lead to lost messages. It also allows multiple programs to access your mailbox at the same time. There is also a LIMITED amount of space for personal webpages.

Checking Mail

To check your mail, you have four options. All these methods access the same mailbox, so changes you make with one method (message deletion, folder creation, etc) will show up under all methods.

  1. Use ssh to connect to cmb, and then use pine. Note that you will have to enter your password again when you start pine. This is because pine is actually accessing your mailbox over the local imap server (since pine has trouble natively dealing with mailboxes in maildir format).
  2. Configure your computer's mail client to use pop3 over ssl (port 995). Each mail client is a little different, so see the documentation for your client program. If you are behind a firewall that blocks port 995, you can also access the pop server over port 9995.
  3. Configure your computer's mail client to use imap over ssl (port 993). Each mail client is a little different, so see the documentation for your client program. If you are behind a firewall that blocks port 993, you can also access the imap server over port 9993.
  4. Access your mail via any web browser at https://cmb.phys.cwru.edu/mail. This interface uses the squirrelmail utility. If you don't immediately see your folders, click on the "folders" link and "subscribe" to the folders you want to use.

Sending Mail

If you connect to cmb via pop-ssl or imap-ssl, you can then use cmb as your outgoing SMTP server. It can take up to 30 seconds from the time you check your mail until you are permitted to relay mail. Permission to relay will expire after a couple hours, and you will need to check your mail again before sending messages out.

Forwarding Mail

If you would prefer to have your cmb mail forwarded elsewhere, simply create a text file in your home directory name ".forward" that contains one line. This line should be the email address where you would like your incoming mail forwarded.

Other Mail Problems and Solutions

  1. Pine sends email that has the "From:" field listed as user@cmb.phys.cwru.edu. If you want pine to use a different "From:" address, go into (S)etup and then (C)onfiguration and modify the custom-headers field so that it has a line like "From: User Name <user@other.domain.org>".

Personal Websites

To create a personal website, go to your home directory and make a directory called "public_html". Any files you put in this directory will be accessable by going to https://cmb.phys.cwru.edu/~user. Note that if you don't want people to see the raw directory listing, you should create an html file named "index.html" and put it in this directory. This webpage will then be the default page that people see.
