-[[#​Printing|{{https://​openclipart.org/​image/​128px/​svg_to_png/​34897/​warszawinka-printer.png | Printing }}]]+This page describes IT services for the former division of Particle Physics.
  
-----+For the division of Particle and Nuclear physics, documentation is not yet available, but most of this content applies.
  
-===== Printing =====+The reference pages for the former division of Theoretical Particle Physics are available here: 
 +https://​dev.thep.lu.se/​computingFAQ/​
  
-**Disclaimer**: Printing is only provided for machines connected to the network via network cableIf you try to print wireless you might not succeedIf you need to print a document, I suggest you transfer it to ''​teddi.hep.lu.se''​ first.+**Accounts** [[it_services:pf#​Accounts|{{ user_icon_3.svg.png?120 |Accounts}}]] | **Backup** [[it_services:​fi:​backuplaptopconf |{{ backup.png?​120 |Backup}}]] | **Printing** [[it_services:​pf:​Printing|{{ 48px-document-print.svg.png?120 |Printing}}]] | **Scanning** [[it_services:​pf:​scan|{{ scanner.png?120 |Scanning}}]] |

-Printing is mostly provided by the //CUPS// server ''​cups.hep.lu.se''​.+----
  
-**Servers** and **Workstations** are automatically connected to all the printers served by it.+====== Accounts ======
  
-These can be usually seen by issuing+===== Particle Physics account =====
  
-  lpstat -a +The Particle Physics account gives access to the following services:
-   +
-at the command line. Example:+
  
-<​code>​pflorido@teddi:​~$ lpstat ​-a +  ​Division ssh gateway 
-clw1 accepting requests since tor 13 feb 2014 19.06.24 +  - print system at particle physics 
-clw1_trans accepting requests since fre  3 maj 2013 09.55.58 +  ​- storage access via Samba for windows and MacOS (only upon request)
-clw2 accepting requests since tis 25 feb 2014 14.43.41 +
-lw1 accepting requests since tis 25 feb 2014 16.35.50 +
-lw4 accepting requests since tis 25 feb 2014 08.52.57 +
-lw4_hpdrivertest accepting requests since mån 18 nov 2013 10.47.04 +
-Ricoh accepting requests since ons 15 jan 2014 17.26.31 +
-</​code>​+
  
-If you have a personal machine or a windows machine you should read further.+==== Division ssh gateway ==== 
 +Gives access to machines inside the division, mostly servers and workstations. 
 +To get an account on the division gateway contact [[:​florido_paganelli|Florido]].  
 +Used mainly to access servers within particle physics nowadays
  
-==== Installation ​====+===== Clusters =====
  
-**Linux laptops** and **Apple or Windows machines** would need to install all the printers manually.+[[:​aurora_cluster|Aurora]]:​ big computations,​ in collaboration with [[https://​www.lunarc.lu.se|Lunarc]]
  
-:!: In our division the printers are not publicly shown in the network, so don't get fooled! if you see a printer in the printer browser might not be ours. Follow the instructions below to be on the safe side.+===== LUCAT accounts =====
  
-=== GNU/Linux ===+I can help out with Lucat issues. This includes: 
 +  * Permissions on your LUCAT ID 
 +  * Temporary eduroam WiFi accounts for conference participants
  
-Get to the printer room **B315a** and note the printer names. You will need those later.+===== Doors =====
  
-There are four ways of installing the drivers:+I can help fixing issues with doors access.
  
-== 1) Safe and Tedious (recommended) == 
-Root privileges: not needed 
  
-use your printer system configurator to add the printer. It may vary depending on distributions.+----
  
-When asked for the printer, choose to add a **network printer** and type in the URL: 
  
-  ipp://cups.hep.lu.se:​631/​printers/<​printername>​ +===== IT Helpdesk ===== 
-   +I take care of helping the staff with their computing
-e.g.+  ​* Technical issues and office devices (screens, keyboards etc) 
 +  * What hardware to buy and ordering hardware 
 +  * Software maintenance and helpdesk 
 +  * Office hours: every day 11:00 - 12:00  
 +  * Available via email anytimeContact me to book a time outside the above.
  
-  ipp://​cups.hep.lu.se:​631/​printers/​lw1 
-  ​ 
-Repeat the above for each printer you want to add. 
  
-This should not require drivers, as they are provided by the CUPS server. Some newer versions of CUPS seem to have problem accepting this fact :-D.+----
  
-Once installed, test with ''​lpstat -a'',​ you should see the list of configured printers. +===== Procurements ===== 
- +I can help out sorting out some of the details ​of public procurementsSweden ​and LU have somewhat strict rules, you can't just buy from anyone.
-== 2) Quick and Advanced (recommended for experts) ​== +
-Root privileges: needed +
- +
-The printers can be added directly to the current cups configuration using a configuration file. +
-:!: **Be careful**: backup ''/​etc/​cups/​printers.conf''​ before you proceed! +
- +
-Follow these steps: +
-  - become root and shut down cups (may vary depending on distribution):​ <​code>​sudo service cups stop</​code>​  +
-  - download this file (sorry I didn't have the time to craft this yet... stay tuned) +
-  - merge or add the contents of the file at the end of your ''/​etc/​cups/​printers.conf''​ file and save. +
-  - restart cups <​code>​sudo service cups start</​code>​ +
-  - test with ''​lpstat -a'',​ you should see the list of configured printers. +
- +
-== 3) Hackish and Fastest ​== +
-Root privileges: needed +
- +
-:!: This solution might prevent you to use printers outside the Particle Physics division. Use it only if you know where to put your hands. +
- +
-Follow these steps: +
- +
-  - become root and shut down cups (may vary depending on distribution):​ <​code>​sudo service cups stop</​code>​  +
-  - add this line to ''/​etc/​cups/​client.conf''​ (create it if it doesn'​t exist): <​code>​ServerName cups.hep.lu.se</​code>​ +
-  - test with ''​lpstat -a'',​ you should see the list of all configured printers. +
- +
-If you use this, remember to comment out the ''​ServerName''​ line in ''​client.conf''​ and restart ''​cups''​ if you travel to a  location outside the premises ​of our division +
- +
-== 4) Evil and Time-consuming == +
-Root privileges: might be needed if you need to install new drivers +
- +
-:?: Why is this evil? because this bypasses the print server. That means that is more likely to jam the print queue in the printer itself (will need a restart) and jam the printer itself if the driver is misconfigured (hopefully a restart will be enough LOL). Use at your own risk. +
- +
-Install the printer drivers yourself, and then install the printer by getting its network address. +
- +
-This may vary depending on the printer vendor, ​and Linux may or may not have the drivers. +
- +
-In shortall you need to do is to provide the hostname of the printerIn most cases it will work if you use +
- +
-  socket://<​printer FQDN>:​9100+
   ​   ​
-e.g. 
  
-  socket://​clw1.hep.lu.se:​9100 +---- 
- +===== Useful links =====
- +
-=== Windows === +
- +
-I will write them when I have time. For the moment being, the only thing I can suggest is: +
- +
-  ​Go to Printers and Faxes and add a new printer +
-  ​When asked for a new printer, select network printer (TCP/IP) +
-  ​Add the printer this way: <​code>​http://​cups.hep-lu.se:​631/​printers/​printername</​code>​ e.g. <​code>​http://​cups.hep.lu.se:​631/​printers/​lw1</​code>​ +
-  - You will be asked for drivers: +
-    - If you have an account on teddi, you might access the drivers folder by entering ''​\\PONGO\shared\windows\drivers''​ in explorer file manager windows. You might be asked for access credentials. +
-    - If you don't have an account on teddi, try on Windows Update. If you're lucky windows will find them for you. +
-    - If Windows update didn't help, come and ask me, I have the drivers. +
-    - If I am not at the division, get the drivers from the vendor. +
-  - When the drivers have been installed, you should be able to use the printer. +
- +
-=== MacOS X === +
- +
-No idea. OSX uses the same CUPS system as linux ,so I guess it's easy. If anybody wants to write this, contact me. +
- +
- +
-==== Printers Status ==== +
- +
-You can check the printers status by connecting to the print server using your browser, at the link cups.hep.lu.se:​631. It is only visible within the division.+
