Background Information for Summer Vacation Students
Getting an account
The first thing you will need is a "CSIRO Ident". This is used to identify you within the pay system, and for your computer account. To set up the Idents, you will be asked to fill in some forms during the human resources session on Monday 5 December.
Two types of account
Once the People Development staff have assigned you an ident, we will create two computer accounts for you. One is a "UNIX account" which works with all the UNIX machines. The other is a "NEXUS account" which gives you access to all the computers running Windows. (NEXUS is the name for CSIRO's Windows authentication domain.) Everyone will need their NEXUS account to access their email.
The UNIX and NEXUS accounts have the same name, but separate passwords. You can use the same password for both if you like, but you should know that the passwords are kept in separate databases and not kept in sync. So if you change one password, the other will not be automatically updated.
The simplest thing is to set your NEXUS password first, and use the same password for your UNIX account. Passwords should be changed every 90 days. You will get an email reminder when it is time to change it.
The information below should get you started. But if you don't ask, you won't get, so don't be afraid to ask questions once you've tried the FAQ's etc.
Frequently asked Questions
- Read The Fine Manual. Try the xman tool to browse the manual pages.
- Start up a web browser and go to our internal help page, and in particular the getting started guide.
- Send mail to firstname.lastname@example.org
Computer help is provided by the CSIRO IT group. This has a central service desk which will either deal with your problem directly, or will find someone who can. Please note that the service desk people who initially respond are not located at the ATNF sites, so if you are sending an email for help, include your phone number and location as well as the details of the problem. In many cases the problem will be forwarded to a local computer support person to deal with.
On UNIX, we recommend pine, mutt, or thunderbird. On Windows, use Outlook.
Mail is stored on a Microsoft Exchange server. When reading mail from a UNIX box, you will have to give your NEXUS password when you want to connect to the mailbox.
Don't try to keep data files in your home directory. There is not enough space.
Do keep draft reports, final plots etc in your home directory. Your home directory is backed up automatically, data disks are not.
For your data, you can book space on shared data disks. They are only visible from UNIX. The space is really yours - no-one else can write to it. However people can read files you store there, unless you change the default file permissions.
The disks have names like /DATA/SERPENS_1. Some disks are scratch space, and are automatically scrubbed. Look for the file SCRATCH_DISK.txt in the top level directory, which explains the scratch-space policy. If that file is not there, the disk is bookable.
To check your booking, use the command
at any UNIX prompt. To renew or change your booking, send mail to email@example.com.
Choose one of these editors
- unix% pico myfile.txt
- unix% nedit myfile.txt
- unix% vi myfile.txt
- unix% emacs myfile.txt
The chooser gives a full list of the
printers available, and their physical location.
The ones used at Epping/Marsfield are typically EPPI-B1LG-82-HP4200 and EPPI-B1LG-23-MX3501. We apologise for the reprehensible naming scheme, it wasn't under our control.
first choose a default printer, see above.
- in black and white:
- lpr myfile.psor
- in colour:
- lpr -PEPPI-B1LG-AWING-MX3501 myfile.ps
On our UNIX systems, there is a special file in your home directory, called .login.packages. This contains a list of all supported packages. Read the instructions in the file to turn access to packages on or off.
On windows, you should contact the helpesk to ask for the package to be installed.
We have a couple of Windows PCs available in the public workstation rooms.
You can also use these programs from UNIX,
This starts an X window containing a PC desktop. It is connecting to a Windows Terminal Server in our data centre. (Under the hood, it is using rdesktop to connect.)
To see your UNIX home directory from Windows, you will have to
"Map a network drive".
Usually we map this to Drive "H".
If you've done this before, when prompted for the folder to map, enter \\lynx\blo123 where blo123 is your UNIX user name.
You may be prompted for a password.
In the username field enter nexus\blo123. In the password field enter your UNIX password.
Note that most applications will not save your work in your UNIX home directory or My Documents folder by default. You will have to navigate the directory tree and select it.
If you have trouble with this, contact the helpdesk.
