All of the Sun workstations have been updated
using a new installation of the latest version of Solaris 8. This is particularly
important for the Data Acquisition server (charissa1) which requires
“real time” scheduling support. Charissa7 is running the current version
of Solaris9.
The 4 Sun workstations are largely independent
of each other and would be able to operate with any of the other systems unavailable. In particular it would
not be a major job to run the Data Acquisition services in any of the Sun workstations in an emergency.
The only important shared discs are hosted by charissa1
§
/MIDAS
§
/usr/local
§
/home/charissa charissa
ID home directory
The second 40 Gbyte disc on charissa2 is
available to everyone as /data.
Each of the 4
workstations has a partition (/space) available for data
files. However on charissa1 this
is the quite small and contains the home directory for the charissa ID. These
partitions are available to everyone as /mnt/spacen where n
is 6 for charissa6 etc.
Both the Sparcstation 20 (old charissa6)
and the Ultra 5 (charissa7) suffered system disc failures. The disc on charissa7
was replaced in April 03. The
contents of the old external discs were copied to the new discs in April 03.
The old individual user home
directories have been preserved and are available as /mnt/space2/homes.
Only the ID charissa is now available for
use.
Please DO NOT change the password of the
group id (charissa).
A number of popular software packages have been
installed (mostly in /usr/local).
These include
§
GNU software package
·
c/c++ compiler (g++)
·
fortran compiler (g77)
·
gzip/gunzip
§
TeX package (tex,latex,dvips,xdvi etc)
§
Emacs
§
ghostscript/ghostview
§
xfig
§
xvgr
§
ssh and scp (secure shell and secure copy)
ssh has been updated to
the latest version in order to be compatible with latest security features.
Email is available from charissa1only
(mail is sent and received as charissa@charissa.anu.edu.au).
The latest version of sendmail (not the Sun
released version) has been installed which contains a number of security
features. The charissa.anu.edu.au
email system has been configured NOT to permit relaying. This
will not effect legitimate use.
It is expected that users will normally remotely
access their University email accounts.
CDE is available on all systems and each of the workstation consoles can be connected for remote login to any of the Sun systems (in exactly the same manner as used by the Xterminals). You are requested to observe the priorities assigned to the Sun workstations and the X terminals which is essentially
§
online data acquisition
§
offline data analysis of the current experiment
§
offline data analysis
§
email access
§
anything else
A firewall has been installed in order to
protect the systems from unwanted attention. For access from the charissa
systems to the outside world this should be transparent but only restricted
access in from the outside is permitted.
All systems now have a single connection to this
secure private network.
The charissa group internal (private) network
uses the IP addresses 128.0.0.xxx
Access internally between machines should use
names of the form charissax only. Do not append anu.edu.au
The firewall provides a DHCP service so
laptops can be connected to an unused port in one of the charissa group network
hubs and configured to obtain an IP address automatically using DHCP.
The address range used is 128.0.0.200 =>
128.0.0.210.
Incoming access is permitted from any source using SMTP to the email server on charissa1.
All other access is permitted only from the campuses at ANU, York, Birmingham and Surrey and from the NP group at Daresbury.
Access is permitted for ftp to charissa1
(as charissa.anu.edu.au) and for ssh to charissa1 (as charissa.anu.edu.au)
using port 1022. [ssh charissa@charissa.anu.edu.au
-p 1022].
A networked printer is also available (Lexmark
Optra T610). Its name is cht610 and address is 128.0.0.40. It is available as the default printer
(t610) on the Sun workstations and is easy to connect to from a Windows laptop
using a Microsoft Standard TCP/IP port.
