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; 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

Printing from laptops: Linux or Mac

Choose "lpr/lpd" printing (not IPP printing); choose host siv, and queue r7lw (room 728), c0lw (room 612) or mslw (room 826); use any PS driver.

Printing from laptops: Windows

You may use LPR printing:
  • on WinXP go to Control Panel, Add/Remove Programs, Windows Components and select/install "Print services for UNIX"
  • on Win7 go to Control Panel, Programs and Features, Windows Features, Print and Document Services and select "LPR Port Monitor"
  • and then go to Add Printer, Local printer, new local LPR port, host siv and some queue as above, use any PS driver.

    Or you may use Samba printing. In a WindowsExplorer, type \\rome in the address bar. First time only, select a printer from the list (e.g. r7lw in room 728, c0lw in room 612, or mslw in room 826) and double-click, let install, then close the resulting queue window; this makes the printer available to all applications. After each reboot go to \\rome to be authenticated, then print.
