| - | ===== Printing ===== | + | ===== Accounts ===== |
| - | **Disclaimer**: Printing is only provided for machines connected to the network via network cable. If you try to print wireless you might not succeed. If you need to print a document, I suggest you transfer it to ''teddi.hep.lu.se'' first. | + | ==== 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 manage personal webpages nowadays. | ||
| - | Printing is mostly provided by the //CUPS// server ''cups.hep.lu.se''. | + | ==== Mail accounts and configuration ==== |
| + | You should have received an email with all the details. | ||
| + | If not, please contact me. | ||
| - | **Servers** and **Workstations** are automatically connected to all the printers served by it. | + | ==== Clusters ==== |
| + | We run two clusters that can be accessed upon request. | ||
| - | These can be usually seen by issuing | + | [[:iridium_cluster|Iridium]]: small computations and code testing. Contact [[:florido_paganelli|Florido]] for an account. |
| - | lpstat -a | + | [[:aurora_cluster|Aurora]]: big computations, in collaboration with [[https://www.lunarc.lu.se|Lunarc]] |
| - | + | ||
| - | at the command line. Example: | + | |
| - | <code>pflorido@teddi:~$ lpstat -a | + | ==== LUCAT accounts ==== |

| - | </code> | + | |
| - | If you have a personal machine or a windows machine you should read further. | + | I can help out with Lucat issues. This includes: |
| + | * Permissions on your LUCAT ID | ||
| + | * Temporary eduroam WiFi accounts for conference participants | ||
| - | ==== Installation ==== | + | ==== Doors ==== |
| - | **Linux laptops** and **Apple or Windows machines** would need to install all the printers manually. | + | I can help fixing issues with doors access. |
| - | :!: 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. | ||
| - | === GNU/Linux === | + | ---- |
| - | Get to the printer room **B315a** and note the printer names. You will need those later. | ||
| - | There are four ways of installing the drivers: | + | ===== IT Helpdesk ===== |
| + | I take care of helping the staff with their computing. | ||
| + | * Technical issues and office devices (screens, keyboards etc) | ||
| + | * What hardware to buy and ordering hardware | ||
| + | * Software maintenance and helpdesk | ||
| - | == 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: | + | ===== Procurements ===== |
| - | + | I can help out sorting out some of the details of public procurements. Sweden and LU have somewhat strict rules, you can't just buy from anyone. | |
| - | ipp://cups.hep.lu.se:631/printers/<printername> | + | |
| | | ||
| - | e.g. | ||
| - | ipp://cups.hep.lu.se:631/printers/lw1 | + | ---- |
| - | + | ===== Useful links ===== | |
| - | 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. | + | |
| - | + | ||
| - | == 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 short, all you need to do is to provide the hostname of the printer. In most cases it will work if you use | + | |
| - | + | ||
| - | socket://<printer FQDN>:9100 | + | |
| - | + | ||
| - | e.g. | + | |
| - | + | ||
| - | socket://clw1.hep.lu.se:9100 | + | |
| - | + | ||
| - | + | ||
| - | === 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. | + | |
