# Testing the IMAP Server

To test the IMAP server, reboot and perform the following steps (all of these samples use "`foobar`" as the IMAP server name). A list of answers to common installation problems is maintained in http://asg.web.cmu.edu/cyrus/imapd/install-FAQ.

1. From your normal account, telnet to the IMAP port on the server you're setting up:

          telnet foobar imap

   If your server is running, you'll get the following message:

          Trying 128.2.232.95...
          Connected to foobar.andrew.cmu.edu.
          Escape character is '^]'.
          * OK foobar.andrew.cmu.edu Cyrus IMAP4 v2.0.0 server ready

   Any message other than one starting with "`* OK`" means there is a problem. To terminate the connection, type "`. logout`".

   Naturally the version number should match the version you just installed.

2. Use "`imtest`" to test logging in with plaintext passwords:

          /usr/local/bin/imtest -m login foobar

   If you want to specify a different user, do:

          /usr/local/bin/imtest -m login -a USER foobar

   If your server is running, you'll get the following message:

          % /usr/local/bin/imtest -m login foobar
          S: * OK mail1.andrew.cmu.edu Cyrus IMAP4 v2.0.0 server ready
          C: C01 CAPABILITY
          S: * CAPABILITY IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ NAMESPACE UIDPLUS
          X-NON-HIERARCHICAL-RENAME NO_ATOMIC_RENAME AUTH=GSSAPI AUTH=ANONYMOUS
          AUTH=KERBEROS_V4 UNSELECT
          S: C01 OK Completed
          Password:
          + go ahead
          L01 OK User logged in
          Authenticated.
          Security strength factor: 0

   Any message other than one starting with a "`L01 OK`" means there is a problem. If the test fails, a more specific error message should be written through `syslog` to the server log. To terminate the connection, type "`. logout`".

3. You should now test the server with each of the various authentication mechanisms you have installed. The supported mechanisms are listed in the CAPABILITY line:

         * CAPABILITY IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ NAMESPACE UIDPLUS
         X-NON-HIERARCHICAL-RENAME NO_ATOMIC_RENAME AUTH=ANONYMOUS
         AUTH=KERBEROS_V4 AUTH=DIGEST-MD5 AUTH=CRAM-MD5 UNSELECT
         . OK Completed

   Each of the mechanism names is preceded by a 'AUTH='. For this example the ANONYMOUS, KERBEROS_V4, DIGEST-MD5, and CRAM-MD5 mechanisms are available. If a mechanism does not appear that you wish to use, examine the libsasl log messages. Generally, if a mechanism does not appear, it means it failed to initialize. (For example, if the server is unable to access the srvtab file the KERBEROS_V4 mechanism will refuse to load.)

   Plaintext login is a special case: the PLAIN SASL mechanism is only advertised under an encrypted connection. However, plaintext logins are available (as long as you haven't disabled plaintext) by using `-m login`(as above).

   To terminate the `imtest` connection, type "`. logout`".

   Once you are satisfied with the authentication mechanism list you should attempt to log in with each of those mechanisms. Run `imtest` specifying which mechanism you would like to use.

          /usr/local/bin/imtest -m KERBEROS_V4 foobar
          C: C01 CAPABILITY
          S: * OK foobar.andrew.cmu.edu Cyrus IMAP4 v2.0.0 server ready
          S: * CAPABILITY IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ NAMESPACE
          UIDPLUS X-NON-HIERARCHICAL-RENAME NO_ATOMIC_RENAME AUTH=ANONYMOUS
          AUTH=GSSAPI AUTH=KERBEROS_V4 UNSELECT
          S: C01 OK Completed
          C: A01 AUTHENTICATE KERBEROS_V4
          S: + wYcDAA==
          C: BAYBQU5EUkVXLkNNVS5FRFUAOCAm7F/Y+HabCzJ
             /UMtVcvWRjTohuq/USaCV6gYdkAU5DOcADAq
          S: + 0aAsUGQZhgQ=
          C: ADMe/cVivAYYzy1yd4Vojg==
          S: A01 OK Success (privacy protection)
          Authenticated.
          Security strength factor: 56

   Any message other than one starting with a "`A01 OK`" means there is a problem. If the test fails, a more specific error message is written through `syslog` to the server log. To terminate the connection, type "`. logout`".

   See the libsasl documentation for a full description of all the mechanisms. It is also possible to support "security layers" (privacy or integrity protected connections). By default, `imtest` uses the strongest layer available with the selected mechanism; use "`-l`" to choose an alternate layer.
