This document is an overview of the University's twelve CIS Unix systems. Please see the Information Technology website for more general information on the panoply of services and technology provided by our department.
All CIS Unix systems reside in the IT Data Center at One Leavitt Lane, about a mile west of the UNH campus. All currently run Red Hat Enterprise Linux version 5 or 6.
UNH Information Technology reserves each Sunday morning from 2:00AM to 12:00PM to perform application and system maintenance. During this time, the CIS Unix systems may not be available. They usually are, though.
Other planned downtimes should be announced in each
machine's login “message of the
day” (the file /etc/motd) and the CIS
Unix Home Page. Unavailability of CIS Unix and other systems
may also be announced on the CIS System Status page. Unplanned downtimes
are not announced.
Login Servers
Two CIS Unix systems are “login servers” for general use by CIS Unix users: their names are “Fermat” and “Newton”.
-
Fermat was purchased in June 2010 and became a CIS Unix server in July of 2011. It is a Dell PowerEdge M610 blade system containing two octo-core Intel Xeon CPUs running at 2.93 GHz, 23.5 gigabytes of memory, and two 136 gigabyte disks in a RAID 1 arrar.
-
Newton arrived at UNH in July 2009, and went into CIS Unix service in November of 2011. It is a Dell PowerEdge M610 blade system containing two eight-core 2.93 GHz Intel Xeon processors, 23.6 gigabytes of memory, and two 67 gigabyte disks in a RAID 1 array.
These servers are available for:
-
General Unix login sessions (see this document for more information);
-
SMTP service for sending mail from your on-campus PC, or (with authorization) your off-campus PC (see this section for more information);
-
POP and IMAP services for reading your mail on your PC (see this section and this section respectively for more information);
-
FTP/SFTP service for transferring files to and from your Unix home directory (see this document for more information)
-
SMB file service for accessing your home directory from on-campus Windows, Macintosh, and Linux computers (see this document for usage details).
- LDAP directory service for (on-campus) lookup of CIS Unix users.
In addition, Fermat provides the “pubpages” World Wide Web service, allowing CIS Unix users to have their own web pages. Issues involved in setting up a web page of your own are described here.
All machines' internet names (“fully-qualified domain names”) are
obtained by appending the university's domain name (.unh.edu) to the machine's name; for
example, Fermat's internet name is fermat.unh.edu.
Our login servers have (as a group) the internet name cisunix.unh.edu; using this name is a
good idea when you want to name either of Fermat or Newton,
but don't really
care which specific one you get.
All standard Linux commands are available on all machines.
You can access the login servers (Fermat or Newton) from any computer attached to the on-campus network. You can also access most services of the login servers from any off-campus computer that has Internet access. (Specifically, SMB, SMTP, and LDAP services are available to on-campus hosts only.)
WebMail Servers
Antrim, Berlin, \ and Lisbon provide the CIS Unix WebMail service described here. These three systems are virtual hosts running under VMWare; they are configured to emulate a single dual-core Xeon CPU, with 7.7 GB of memory.
Mail Gateway Servers
Jaffrey, Granite, Freedom, and Sunapee arrived in spring 2007, and went operational in the spring and summer of 2007. They handle all incoming and outgoing mail for the CIS Unix systems, as well as a good fraction of mail destined for other servers. These are identical Dell 2950 systems, each with two quad-core 2.66GH Intel Xeon CPUs, 4 gigabytes of memory, and a 117 gigabyte (effective size) RAID array.
System Administration Server
Goshen is a virtual host running under VMWare; it is configured with 2 GB of memory. It provides Domain Name Service (DNS) and Network Time Protocol (NTP) services to the other systems. It runs the account management softare and keeps the master copies of various account-related databases. It runs virus-scanning software to detect and destroy (typically) Windows worms and viruses in user files.
