Computing Information for Visitors

Your account

A Linux account on the server dora, and a Windows/Samba account, will be set up for you. You will be asked to nominate passwords (say 6 to 8 characters including non-letters, different from passwords you use elsewhere). Please remember the passwords without writing them down, to preserve secrecy.

The Linux account is accessible from all office Y-terminals by selecting the item dora in the menu of hosts. If a Y-terminal (smallish black or grey box) is present, please use that in preference to a PC. There is a Y-terminal suitable for visitors in room 612, just to the right of the door.

Some office PCs are suitable for accessing the Linux system and some are not, so if only a PC is present, please check with computing staff whether it is suitable before attempting to use or disconnect it. (Office Macs are not suitable for visitors.) On suitable PCs running Windows, you can log in with username dora and password dora, then log in on your dora visitor account; or you can directly log in to Windows with Samba. There is a Windows PC suitable for visitors in room 612.

If there is no Y-terminal or suitable PC in the office allocated to you, try room 612. Or you may use the computers in the undergrad computing laboratories (rooms 610/611 on the sixth floor, and 729/730 or 705/706 on the seventh floor), that contain Linux terminals normally showing a login screen to the undergrad server zeno; on that screen press the Esc key, then quickly choose dora by pressing the d key or clicking; log in to dora and work; then when logging out, let the terminal revert to a zeno login.

Your account and any remaining files will be deleted shortly after your departure date.

Software available

The Firefox web browser and the Thunderbird mail client are recommended. (Thunderbird uses the Samba/Windows password.)

You can use the commands telnet and/or ssh to log in to your home system from dora.

Other access: laptops

If you have brought a laptop with you and it has an RJ-45 UTP Ethernet port, it may be possible to provide a connection for it in your office, please ask if interested: please see here about some setup; you would also need to set up automatic network address recognition via DHCP yourself; web browsers should be set to use direct access (no proxies needed, the connection is behind a transparent proxy firewall).

It is also possible to arrange for a telnet or ssh connection (to your Linux account on dora) from where you are staying, with a sheet of one-time Skey passwords: see the incoming ssh link on the School Local Front Page http://www.maths.usyd.edu.au/local.html.

Printing from laptops

You can use CUPS/IPP printing, or LPR/LPD printing. For names and locations of all our printers, that you can use with LPR, see http://www.maths.usyd.edu.au/loc/comp/alpha/printing.html; for the subset you can use with CUPS, see http://siv:631/printers.

Printing from laptops: Linux

Note that some software can CUPS, some can use LPR, some can use both.

For CUPS: set the server to be siv: either have the line
CUPS_SERVER=siv
in your /etc/environ file, or have the line
ServerName siv
in your /etc/cups/client.conf file.
Or maybe, set up each printer: host siv, and queue r7lw (or c0lw mslw etc); use any (generic?) PS driver.

For LPR/LPD: set up (each) printer by choosing host siv, and queue r7lw (or c0lw mslw etc); use any (generic?) PS driver.

Printing from laptops: Mac

For CUPS: On recents Macs (MacOSX 10.7 or later), set up each printer by going to System Preferences, Printers & Scanners, and click the + sign at the bottom of the (empty?) list. If you do not see the Advanced type, then right-click in the space to the right of the types (between Windows and Search), choose Customize toolbar and drag the Advanced icon to the toolbar; click Done. Choose Advanced (wait while it does some search), choose type Internet Printing Protocol - http, URL http://siv:631/printers/r7lw (or c0lw mslw etc); choose some name, use (driver) Generic PostScript Printer; click Add.
See the above process explained with pretty pictures.
I wonder why Apple broke their own software: up until MacOSX 10.6, setting
ServerName siv
in file /etc/cups/client.conf worked just fine.

For LPR/LPD: In System Preferences, Printers & Scanners, set up each printer by clicking the + sign at the bottom of the list, choose type IP and Line Printer Daemon - LPD, address siv and queue r7lw (or c0lw mslw etc); some name; use any (generic?) PS driver.

Printing from laptops: Windows

For CUPS or LPR printing: first (once only) go to Control Panel, Programs and Features, Windows Features, Print and Document Services and select (either or both) Internet Printing Client (for CUPS) or LPR Port Monitor (for LPR).

For CUPS: go to Control Panel, Devices and Printers, choose Add a Printer, then click The printer that I want isn't listed at the bottom. Choose Select a shared printer by name and type name http://siv:631/printers/r7lw (or c0lw mslw etc); use any PS driver (e.g. HP LaserJet 2500 PS).

For LPR: go to Control Panel, Devices and Printers, choose Add a Printer, then click The printer that I want isn't listed at the bottom. Choose Add a local printer or network printer with manual settings, with a new LPR port, host siv and queue r7lw (or c0lw mslw etc); some name; use any PS driver (e.g. HP LaserJet 2500 PS).
