To help with this, I’ve decided to write it all up once and for all. For the sake of example, I’m going to assume that you want to authenticate against the realms ANDREW.CMU.EDU and CS.CMU.EDU using the username gandalf. The first step is to set your Kerberos credentials cache to be a directory so that individual Kerberos tickets from different realms do not conflict each other. /blog/2017-09-21-configuring-the-cmu-scs-public-printer-on-linux/ Thu, 21 Sep 2017 09:56:00 -0400 /blog/2017-09-21-configuring-the-cmu-scs-public-printer-on-linux/ A year ago, I wrote a post on Configuring CMU SCS printers on Linux. SCS Computing Facilities is rolling out a new single-queue print system, where you fetch your job from the queue to a particular printer using your ID card. They don’t provide instructions for configuring this on unfacilitized hosts, so here’s what worked for me. Edit 3: They’ve added instructions, copied (almost) verbatim and without attribution from below, here. /blog/2016-08-15-configuring-cmu-scs-printers-on-linux/ Mon, 15 Aug 2016 09:32:00 -0400 /blog/2016-08-15-configuring-cmu-scs-printers-on-linux/ Edit: Please see these instructions for printing to the centralised SCS-Public print queue. Unless your Linux host was “facilitized” (i.e., unless you’re still running the stock Linux install provided by the CMU help desk), you’re probably scratching your head as to how to add SCS printers to your Linux host. Here’s how. (NOTE: You should only add SCS printers if you have an SCS account!) A list of public network printers is conveniently available here.
