Software and Services
IPTables
Einstein uses the standard NPG iptables firewall. It allows ssh, LDAP, imap, smtp, and http connections.
LDAP
Einstein is our LDAP server. It provides user authentication among other useful services. LDAP configuration is located in /etc/openldap, and the LDAP database is stored in /var/lib/ldap.
Einstein is our Email server. The mail itself is stored in a raid1 volume on Gourd, and Einstein mounts the NFS share to /var/spool/mail.
Einstein should mount the NFS share at boot, but note that since it mounts gourd by hostname you should make sure that DNS is accessible before starting the Einstein VM. Otherwise mail won't be mounted properly on boot. If for some reason DNS is unreachable you can manually mount the NFS using gourd's IP address directly once Einstein has booted.
Webmail
Einstein provides web-based access to e-mail using Squirrelmail. You can access it at [1].
