| Adding an AU smb printer via CLI. | ||
| Syntax: install_printer [-P|-L|-h] | ||
| options: | ||
| -P name Printer to be added. | ||
| -L location Where the printer is located | ||
| -N Do not check that the printer exists using smbclient | ||
| -l List the printers using smbclient | ||
| -h Print this Help. | ||
| If the -P or -L values are not given we instead prompt for them. | ||
| Note that we will use the generic driver, this can be changed manually afterwards. | ||
| -l can be prepended by ' | grep 1530 ' to find all printers in 1530 | ||
| Easter egg: if the printer name is just a building number, the | ||
| programme lists the printers in that building. | ||

| Did not find a valid AU Kerberos ticket. We need a ticket to ease | ||
| communication with the printserver (to avoid username and password all | ||
| the time). Please run the following command to create an AU ticket: | ||
| kinit [email protected] | ||
| with your own auAUID (remember the au in front). Note that the | ||
| uppercase "@UNI.AU.DK" is REQUIRED, lowercase does not work. | ||
| NB: 'kinit' will ask for your AU password. | ||
| Afterwards you can run 'klist -l' to see if it specifies something. This | ||
| will also tell you for how long your ticket is valid. | ||
| Once a ticket is availalbe you can rerun "$0". | ||
| Please note that the ticket is only used for the installation via this | ||
| programme. Specifying username and password when printing is handled | ||
| elsewhere. | ||

| #Ændret printer-check da den godtog fx "1521" som printer findes | ||
| #Tilføjet at den viser printere i bygningen, hvis printer-check fejler. | ||
| #Tilføjet at den viser den installerede printer ud til sidst med model, så det er nemmere at finde driver efterfølgende. | ||
| # Added checks for smbclient, klist and lpadmin | ||
| # Added checks for valid AU kerberos ticket | ||
| # Fixed bug where a building with just one printer could trigger installation. Printer name need to match eactly | ||
| # Removed the use of sudo to run the lpadmin command | ||
| # Changed how KRB_CACHE_LOCATION finds the cache file |
