It varies a lot, but it comes down to just writing code, submitting it, and repeating. You should mention that you're working on it on the mailing list to avoid duplicating work and get help. If your work is good, the maintainers will include it. If it's bad, they'll ask you to fix it. Eventually, if you submit enough good code, you earn trust and can become a maintainer and check code in yourself. If they don't accept your code, you fork the project and put the patched version on your web site. :)

It pretty much boils down to: - pick the project you want to join - sign up for the mailing lists, and probably issue trackers and a wiki - read up on the current state of the project (bonus if it has a "future plans" document somewhere - start asking questions on the mailing lists - pick a piece that looks interesting, and start writing and submitting code Writing documentation is nearly always a good place to start. Many projects have docs that are incomplete, or out of date, and writing docs doesn't require nearly the same level of initial work to get started that writing actual code does. > Are > they all parts of large corporations or schools? I just read that CISCO is > embracing the open source idea. Oh course, I shall get hold of them. Some are, but quite a few have no such backing affiliation. Even many of the ones that have a backer now, didn't initially. The Bacula project, one I'm moderately active in, started off as a pet project by a couple of programmers. Now, the primary programmer is actually building a consulting business around it. Another one, the Puppet configuration management system, was written by the author as a tool to help him in his job as a sysadmin consultant. He chose to open source it, in the hopes that it could be useful to others, and that others, finding it useful, would contribute back to it. Both are coming true, and as a result he has a tool that's far more powerful than anything he could have written completely on his own. In the end, the one common thread you're likely to find among the vast majority of open source communities is a small group - often one or two people - would had a particular itch that they could not scratch, and so decided to start up their own project to fix it. As programs like linux and the various GNU software show, that kind of deep motivation can produce impressive results, even without the traditional corporate support structure. -- Frank Sweetser fs at wpi.edu | For every problem, there is a solution that WPI Senior Network Engineer | is simple, elegant, and wrong. - HL Mencken GPG fingerprint = 6174 1257 129E 0D21 D8D4 E8A3 8E39 29E3 E2E8 8CEC

Last week I was stuck. I had a broken SUN sparc64 ULTRA ONE. I asked WLUG for help. John Stoffel rose to the bait. My SUN now works better than ever. (We installed four fast ethernet ports thereby replacing a broken old fashioned eth0.) Thank you (publicly) John. I have another question. I am a retired computer programmer. I ended my professional days as a Senior Software Engineer for CISCO Systems in 2004. I am getting bored. (and my 401k is getting hit). I am curious as to whether I can contribute to an Open Source project. How do I join an open source community? Are they all parts of large corporations or schools? I just read that CISCO is embracing the open source idea. Oh course, I shall get hold of them. Do any of you have some knowledge on this subject? Ken Jones

Re: [Wlug] Hyper Terminal into SUN SPARC ULTRA??

by John Stoffel

Ken> I still have not solved how to get my AURORA LINUX package to see Ken> the added SBUS quad ethernet card in my SUN SPARC ULTRA --so---> Let's see if I remember correctly. The Ultra 1 probably has an HME (Happy Meal Ethernet) interface card, which is 10/100. The quad card you put in is probably a QFE card. Can you boot up the system and see what modules you have in /lib/modules* and also post your dmesg output and lsmod output as well?

Ken> I am stuck figuring out how to get the SUN to activate this asynchronous interface. Umm... by default the Sparcs will use ttya as the console input/output if you don't have a keyboard hooked upto the system. Do you have one hooked up when you boot or is it headless? Here's what I'd do: - power off the system. - hook up the serial cable to port A on the Sparc, and COM1 on your PC. Make sure it's a null-modem cable. - unhook any keyboard on the sun. - fire up hyperterm and set to 9600 baud. - start the sparc. You should see output. Send a BREAK sequence (ESC-F I think) to get to the 'ok' prompt on the Sparc. - you should be all set to type, etc. The real issue, as someone else said, is that you need to modify the /etc/inittab file to have a line like this: cd:2345:respawn:/sbin/agetty console 9600 vt100 so that you'll have serial access from both the low level PROM, and from Linux. Basically, you should be able hookup adn use the quad ethernet card, you might just need to load the proper module, or re-compile the kernel to have support for that module. More details will help us to help you. The other solution would be to boot the machine, and then setup a ppp link (or even slip) over a serial port to another computer and then you could scp/ftp the file(s) over to a system with a working ethernet port. Depends on whether you have PPP packages installed or not. And whether you have another linux box available to act as the other end of the link. I know very little about PPP on a windows box and I don't want to go there if I can help it. Pulling the disks and putting them into another SCSI system would also let you get the data off there. Hope this helps. John

Need to edit /etc/inittab.

Hyper Terminal into SUN SPARC ULTRA??

by Ken Jones

I still have not solved how to get my AURORA LINUX package to see the added SBUS quad ethernet card in my SUN SPARC ULTRA --so---> I am after some of the files that I have stored on this SAMBA server. I figured I could use Hyper Terminal. I have an appropriate cross over cable with a 24 pin connector to plug into the SPARC's Terminal A or Terminal B. I can configure Hyper Terminal on my PC running WINDOWS XP. I am stuck figuring out how to get the SUN to activate this asynchronous interface. Any suggestions?

I'm not familiar w/aurora Aurora is a Linux distro for SPARC-based systems. It is based on the Fedora SRPMs. The second "stable" build of Aurora (2.0) is based on Fedora Core 3, and the Corona Tree is an almost feature complete tree based on Fedora Core 6. (This, according to the Aurora Status notes.) You can find more info on Aurora and download it at http://auroralinux.org/ .

Problem Sparc ULTRA 1 not seeing SBus Fast Ethernet

by Ken Jones

I have a Sparc Ultra 1 which has been running flawlessly since 2003 running Ansel 2.4.20-2.3sparc. Last week after a nine day power outage the system no longer activates eth0, the TPE ethernet interface. I installed a --> Sun 501-5443 x1049A quad 4-port SBus Fast Ethernet card The operating system does not recognize this new hardware. This system has been running so flawlessly for at least four years that I have forgotten much of what I had learned about Aurora.(I am an elderly man by high tech standards). The little green input light corresponding to the port to which I have attached the fast ethernet cable does illuminate. Where do I start? Ken Jones
