Computing Information for Visitors

Your account

A Linux account on the server enna will be set up for you. You will be asked to nominate a password (different from passwords you use elsewhere).

The Linux account is accessible from all office Y-terminals by selecting the item enna in the menu of hosts. There is a Y-terminal suitable for visitors in room 612, just to the right of the door; or maybe use one of the terminals in the "honours students" room 729/730.

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 enna.

Other access: laptops (and other non-School-managed computers)

Wireless

Wireless networks are operated by central ICT (not by Maths support), please see https://www.maths.usyd.edu.au/s/scnitm/psz-Laptops-WirelessAndWiredC.

Wired network

If you have a laptop or other computer (including ICT-managed PCs and Macs) and it has an RJ-45 UTP Ethernet port, it may be possible to provide a connection for it in your office (on our internal School network), please ask if interested: please see https://www.maths.usyd.edu.au/s/scnitm/psz-Laptops-WirelessAndWiredC about some setup. (You need to set automatic network address recognition via DHCP, and set web browsers to use direct access i.e. no proxies. The connection is behind a transparent proxy firewall).

SSH access

You may access your Linux account on enna via ssh, with plain password from the School internal wired network, or with 2-factor authentication (e.g. from "home" or from a wireless connection): see https://www.maths.usyd.edu.au/u/psz/ssh-howto.html instructions, maybe also the incoming ssh link on the School Local Front Page https://www.maths.usyd.edu.au/local.html for some comments.

Printing

You may (or not) be able to use ICT FMP (Follow-Me Printing), please see the ICT KB article
https://sydneyuni.service-now.com/sm?id=kb_article_view&sysparm_article=KB0011262
There are two FMP printers in the School, the Fuji devices in rooms 728 and 533.
Linux users see here for more detail.

School printing

ONLY when connected to the (wired, internal) School network ...

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

Printing from Linux

Note that some software can use 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 Mac

For CUPS: On recent Macs (since MacOSX 11 or so), set up each printer by going to System Preferences, Printers & Scanners, and click add printer at the bottom of the (empty?) list. Choose type IP and Internet Printing Protocol - IPP, address siv:631 and queue printers/r7lw (or printers/c0lw printers/mslw etc); choose some name, use (driver) Generic PostScript Printer; click Add.
I wonder why Apple broke their very own software: up until MacOSX 10.6, setting
ServerName siv
in file /etc/cups/client.conf worked just fine.
Some web references suggest to use a command something like
lpadmin -p 'r7lw in 728' -E -v ipp://siv:631/printers/r7lw -m everywhere
instead of the rigmarole with SystemPreferences.

For LPR/LPD: Set up each printer by going to System Preferences, Printers & Scanners, and click add printer 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 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).

Below it says any PS driver: almost any, but certainly not the Microsoft PS (PostScript) one. In the driver selection menu, maybe click WindowsUpdate, and (after several minutes!) see it populated with many drivers. Some that seem to work well are HP LaserJet 2500 PS and HP LaserJet 3050 Series PS, as well as the "proper" Ricoh MP7500 PS and Ricoh SP C420 PS drivers.

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.maths.usyd.edu.au:631/printers/r7lw (or c0lw mslw etc); use any PS driver.

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.maths.usyd.edu.au and queue r7lw (or c0lw mslw etc); some name; use any PS driver.
