information about Engineering servers
email servers
Here are the names you should use when configuring an email client located within the College of Engineering:
outgoing email server (SMTP server): smtp.eng.uah.edu
POP3 server: pop.eng.uah.edu
IMAP server: imap.eng.uah.edu
All servers are normal (i.e., non-SSL) connections. A secure IMAP connection is available using the standard IMAPS port 993. Note this uses a self-signed certificate, so you may receive warnings from your email client.
webmail server: webmail.eng.uah.edu
non-Engineering connections : You may retreive your email from off campus using the POP3 or IMAP servers, but you may not send outgoing email via the Engineering servers unless you are within the College of Engineering (that is, in one of the following buildings on campus: EB, TH, OB, MSB).
webmail server
webmail.eng.uah.edu is the web interface for the College of Engineering email.
It is strongly recommended that you use a secure connection to the webmail server to prevent interception of your password.
Your web browser will give you a warning when you access the webmail secure connection. This is normal and due to the fact that our security certificate has not been registered with a certificate authority (at a recurring cost). Most web broswers will allow you to accept certificates from an authority not on the default list; doing so for this certificate will bypass the warning for future sessions.
vulcan: license server
zeus: mail server, NFS server, NIS (yellow pages) server
mail server : zeus is the primary email server for the College. It receives email for the eng.uah.edu, ece.uah.edu, ise.uah.edu, mae.uah.edu, che.uah.edu, and cee.uah.edu domains. zeus provides POP3 and IMAP services used by a variety of email clients.
NIS master : zeus is the master server for the eng.uah.edu NIS domain. NIS (formerly known as yellow pages, or yp) provides the services required to administer a group of Unix systems as a single entity.
NFS server : zeus is the NFS server that provides filesystems containing eng.uah.edu users' home directories as well as applications used by the Engineering Suns.
mercury : virus scanning email server
mercury is the virus scanning email server for the College of Engineering. It responds to smtp.eng.uah.edu, and should be used as the outgoing email server for Engineering users in EB, TH, OB, and MSB.
ray: application server
application server : If you need to ssh in to an Engineering Sun to run an application, ray is the correct machine to use. It has the CPU, RAM, and swap space to handle multiple users and multiple applications.
Note that ray.eng.uah.edu is an alias for another machine (sr4 at the time of this update). The machine itself may change, but a computer appropriate for running applications will respond to ray.eng.uah.edu.
sr1, sr2, sr3, sr4 : Sunray servers
Provide login services and application services for Unix Labs I and II (EB216 and EB246).
Note: There is no need to ssh or telnet anywhere to run an application if you are in one of the sun labs already - use the machine in front of you instead of logging in elsewhere.
w2 : web server, FTP server
web server : w2 is the primary web server for the College of Engineering. College of Engineering departments, research groups, student organizations, and eb.uah.edu users are provided web service by this server. www also provides web oriented online documentation for applications used by the College.
FTP server : the web server also provides unrestricted FTP access via ftp.eng.uah.edu. Security policies restrict access to College of Engineering Unix systems,especially servers. This FTP server is left open so you may access your data any time from any where, but be aware that your account security and your data can be compromised if you use this method.
It is strongly recommended that you use a secure method of file transfer, such as scp or sftp.
anonymous FTP server : anonymous FTP allows you to exchange data with others anywhere in the world. The public directory is readable by anyone.
Be aware that anyone can read or overwrite this data, so do not transfer sensitive data here, and make sure you have a copy saved elsewhere.
bragg : Sun SMP
bragg is an 8 processor SMP UltraSPARC system used primarily for parallel programming courses (CPE412/512/612).
Bragg is a Sun Enterprise 4500 with 2Gb of RAM and eight 250MHz UltraSPARC processors with two processors per processor board.
x12 : cluster
x12 is a 32 node beowulf cluster dedicated to parallel programming courses CPE412/512/612.
The x12 server is a dual processor 3.2GHz Xeon with hyperthreading. Jobs should
not be executed on the server as this negatively impacts the performance of the entire cluster.
Nodes n01 - n16 are 3.2GHz Pentium 4 Hyperthreading enabled processors, 800MHz FSB, 512k L2 cache.
Nodes n17 - n32 are 3.2GHz Pentium 4 Hyperthreading enabled processors, 800MHz FSB, 1M L2 cache.
note: the difference between nodes 1-16 and 17-32 are 512k cache vs. 1M cache.
The interconnect network is a dedicated switched gigabit ethernet consisting of two Dell PowerEdge 5x24 switches with a single uplink.
Accounts are standard engineering unix accounts (Sun accounts) that have been granted access to x12. Home directories are not common between the cluster and the Suns for performance reasons. Cluster users' home directories are on a software RAID mirror residing on x12. No backups are performed on this system.
Future work: plans for future improvements include the addition of a batch queueing system (probably torque) and expanding the uplink connection between switches to four 1 gigabit connections.
