Hey Gang, WPI is going to be locked down for commencement on the 9th. I'm moving the meeting to the 16th due to commencement. The planned topic is gaming on linux.

Re: struggling w/ reliable printers on CUPS in small office

by Bradley Noyes

I thought i’d respond to this thread to circle back on my solution, which mostly works. The progression of printer connections was the following, the last one is the one that worked. imacs ——> WiFi (dhcp) ——> HP Printer imacs ——> ethernet (dhcp) ——> HP Printer imacs ——> ethernet (static IP) ——> HP Printer imacs ——> ethernet ——> Linux Cups Server ——> ethernet ——> HP Printer imacs ——> ethernet ——> Linux Cups Server ——> USB (over rj45) ——> HP Printer imacs ——> ethernat ——> Linux Cups Server on Raspberry PI ——> USB ——> HP Printer As mentioned by contributors to this thread, the network stack on the HP Printers seem to be flaky, so any attempt that involved the HP Printer’s network stack would fail at some point. Its strange that all of the HP Printers in the office seem to be affected by this. Everything i tired that involved a network link to the HP Printers was very flaky. My second-to-last ditch effort was to try using USB over ethernet; since the printers and the Linux Cups Server are not physically close and i have network drops next to each, i tried the USB over ethernet dongles, which didn’t take. The devies were recognized, but i couldn’t print over the USB device. There were some postings online about setting some serial parameters, but i didn’t want to mess around with it too much. So my final solution was to use an old Raspberry Pi i had kicking around which can be placed next to the printers and connect via USB, and it can also be connected to the office network via ethernet. This has been rock solid and clears my desk of an old r-Pi. In the end i can’t really come to a conclusion other that the HP Printer’s TCP stack is flaky. The rest of the network seems to be fine, i’ve never seen any troubles with anything else on the network. I’d occasional see the printer’s settings claim it is on-line, but have no IP address, which was always suspect to me. the printers operate reliably if using USB. Anyway, just wanted to let y’all know that a raspberry-pi running CUPS was the best solution, and thank you for responding.

Reminder: Meeting April 18th. Topic: Open Broadcast System Location: Stratton Hall Rm 106

by Tim Keller

Hey Everybody, This Thursday at 7pm in Stratton Hall rm 106, wlug member Ian Gelman will be doing a talk about the Open Broadcast system. OBS (https://obsproject.com/) is free, open source software that allows you turn your Linux system into a powerful mobile TV studio. If you’ve watched any online content creators in the past couple of years, you’ve likely seen the software in action. In this talk, I’ll be giving an overview of what the software can do, as well as a case study on how OBS helped rocket a simple clementine to the top of the WPI subreddit. ( http://wpiwa.wpi.edu/clementine.html) We’ll finish up with a live demo where we’ll create a stream with some webcam footage, application displays, and an internet radio station. Snacks and Refreshments will be provided and afterwards we'll head off for dinner. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Arcade Machine Problem

by Dennis Payne

My son's cub scout den put together an arcade machine for the Build It pin. It worked great. Then the day of the Blue & Gold where we were demoing it, it didn't work. I ended up using my laptop instead of the intended machine. I have now set it up four times on three computers and have discovered the cause of the problem. The machine is running Fedora. It has only one user and he automatically logs in. It is running wayland. Gnome is configured to automatically start EmulationStation. From there you can launch Ostrich Riders or Super Tux Kart. (I wanted only open source games with two players simultaneous preferably cooperative but more games can be put on.) The problem occurs if the machine does not have a mouse plugged in. EmulationStation starts normally but launching either game brings up the login screen. Any idea why a mouse is required and how that restriction can be removed? -- Dennis Payne dulsi(a)identicalsoftware.com https://social.freegamedev.net/channel/dulsi

aging/free books for DNS,LDAP,TCP...*NIX+BSD

by Doug Mildram

"Old" books in some cases, but some protocols never age out! (some of below maybe did...) Free books on my desk here at work/WPI, if unwanted I'll end up tossing: (2005) Addison-Wesley "The Design and Implementation of the FreeBSD OS" I got glassy-eyed diving into most of this kernel,fsys,devices,IPC,etc gore. (2003) ORA/O'Reilly "DNS & BIND Cookbook" (bind8,9) Cricket Liu 200+ pg paperback (2003) ORA "LDAP System Administration" Gerald Carter 290pg paperback (1994) Addison-Wesley "TCP/IP Illustrated, Vol. 1" W. Richard Stevens 550pg hardcover (1990) Prentice Hall "UNIX Network Programming" W. Richard Stevens 750pg hardcover ( things like fork/exec ; basic I/O ; FIFO,IPC,Sockets,TLI...ending in rlogin :) TOO OLD (1993) ORA "sendmail" ( v8 ) too old AND too nasty, though I like the Intro sec1+2 titles "MUA vs MTA" and "Why is sendmail so complex?"
