Astronomy ComputingWe provide a number of public computers and peripherals for general use
by our visiting astronomers
. We kindly ask our users to follow the conditions of
use for ING
computers and networks. The information given below does not include the computers or the user accounts of the telescopes'
observing systems.
Two computer user accounts are allocated for your observing run by default, observer and guest, details of which
are
available from your Support Astronomer (SA). The observer account can only be used to run the observing system, while the guest account can be used for reducing data, analysis, etc. Note that files in the root directory of the observer account are removed after 2 weeks. If you wish to keep an observing script, make a directory and save it there.
We can provide you with up to 3 additional guest accounts if necessary (see the current account assignments. For more guest accounts that you might require, or if you are visiting the ING and you need an account, please complete the Computing Facilities Questionnaire for visiting astronomers. Certain access restrictions are applicable when using these guest accounts. In accordance with the ING Computer Security Policy, guest accounts are provided to be used within the ING network domain. That is to say, access to ING resources via these accounts is only permitted if the user is on ING premises. The following links show the available desktops, software and other hardware available to visitors and observers: at the WHT, at the INT, and at the SLO .
Please be aware that the use of the email outgoing ports 25 (SMTP) and 465 (SMTPS) within the ING network is not permitted, unless used for connecting with an ING email server. As a consequence you can read but not send out email using, for instance, an application on your laptop to connect with your usual email server. Alternative ways to email from within the ING network like webemail, or SSH, VPN or EDUROAM connections are not affected by this network security restriction. ING's wireless external network ingext is password-protected at the WHT and INT control rooms, please contact your SA or Observing Support Assistant (OSA) to get the password, or check your visitor's pack upon your arrival. For accessing ingext elsewhere (WHT's building, INT's dinning room, Residencia's lounge or ING's sea-level office) registering the MAC address of your wifi card on your device is necessary, please submit a Computing Facilities Questionnaire for visiting astronomers. ingext requires Dynamic Host Configuration Protocol (DHCP), no static IP addresses are available.You can apply for a cable network access, based on DHCP. Please provide your ethernet MAC address using the Computing Facilities Questionnaire for visiting astronomers. You can use any of the spare wall UTP ports, although we strongly recommend those marked as "General Ports". Keep the wall port free if not being used. In case you are not using DHCP, we also provide some static IP addresses at the disposal of the visitors if the ethernet MAC address wasn't registered previously. IAC operates a wireless network at the Residencia that can be accessed from the bedrooms. Details on how to use it can be obtained at the reception of the Residencia. ING also provides a network hub in the computer room of the Residencia. For plugging your computer there you need DHCP and registering your ethernet's MAC address using the Computing Facilities Questionnaire for visiting astronomers. Users of Macintosh are requested to contact the ING Computing Group using the Computing Facilities Questionnaire for visiting astronomers well in advance of their visit, if they suspect that they will require any specific support for their computers.

For any reasons, edit (create, modify or remove) any data files from the /obsdata/whta or /obsdata/inta directories. It is an ING policy that all astronomical images are archived and eventually sent to the image archive operated by the CASU Astronomical Data Centre in Cambridge (see the ING data ownership policy for more information. To ensure that all images are archived, please do not delete any files on the observing directories. If you need to recover any data or an observational log of your run during the propietary period, your request will need to be made via the ING Astronomy Group. Please contact the Support Astronomer of your observing run or the Head of Astronomy. The following are data areas at the disposal of visitors:
To work with observational data, first copy the files to a scratch area (the ones shown in the table above or any of the local ones, ie. /scratch/ComputerName). Do not use the /obsdata or /home directories for data storage or reduction. Please be aware that scratch areas are not backed up and files older than 1 year could be removed without previous warning if free disk capacity drops below 5%. For working on data longer, use the safe areas /data/UserName. The following printers are available to users:
Below are examples of how to print from a Linux computer:
Where <printer> is the printer's name as provided in the first column of the table above, except otherwise noted. If you need to print from your laptop using ingext network, please follow the instructions on how to print to ING printers as a guest. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
