System Details
The
cluster machines (known as session servers) are as follows:
Session Servers
---------------
holmes.umd.edu
marlowe.umd.edu
marple.umd.edu
tracy.umd.edu
wolfe.umd.edu
To
make all this easier, users of the OIT Unix cluster can just login to the
generic address dc.umd.edu (dc = detective cluster).
All mail sent to
the cluster should
be addressed to <login-id>@umd5.umd.edu (which
is the address that is placed
on all outgoing cluster mail). Mail sent
in this manner can be read from any cluster system. The machine known as umd5.umd.edu is also
part of the cluster but acts as a server for the cluster. DO NOT USE UMD5
for anything other than your EMAIL address. Never login to umd5.
Games,
IRC, and MUDs are not allowed on the OIT Unix
cluster.
Help
Questions should be directed to the OIT Help Desk (CSS West Wing
room 1400) at 301-405-1500, 8:00 a.m. - 5:00
p.m., Monday - Friday.
Documentation (Introduction to the OIT Unix System) is available at:
http://www.helpdesk.umd.edu/documentation
News
OIT
uses the Usenet news system on its
Unix systems to
inform users about system
outages, new software,
etc. The news group csc.news is used for all news items. Items that are considered of interest to
the general University
community are also placed in the um.general news
group.
The
default .login file contains a call to the readnews program. On some
systems, users prefer to use the rn program to
read news. If rn
is used, the call to readnews should be
removed from the
users' .login file.
Printing
OIT has replaced the stock lpr
program with a shell script that calls MDQS to print a file on prl, which is
the 3800 laser
printer attached to the campus IBM system.
The
call is lpr
<file> to initiate printing
of file <file>.
Output
may be retrieved at the OIT dispatch counter in room 1299 of the A.V.
Williams I building.
File
Recovery
A
dump of all files is taken every week.
These file backups are for recovery from catastrophic loss. Individual user file recovery is not
available at this time.
/tmp and /var/tmp
/tmp is a small directory used by system utilities
for short term scratch files. Users should not place their files in /tmp. User
files should be placed in user directories (every user has one) or /var/tmp
(again, short term storage).
Files
residing in /tmp and /var/tmp can be deleted without notice if disk space becomes
critical.
/tmp and /var/tmp
are local to each system in the cluster.
Software
The
cluster file /usr/local/doc/cluster
contains cluster details, including a table showing software
availability. Please read
this file for full cluster details.
