REMINDER: Upcoming WLUG Meeting
by Andy Stewart 08 Apr '07

08 Apr '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI Everybody, We have a WLUG meeting coming up on Wednesday, April 11th, at 7:00 PM in the Access Grid room on the WPI campus in Worcester, MA USA. At this meeting, Andy Stewart will give a presentation on his recent work with the Delcom USB I/O Development Board. Part of this work involves writing a Linux kernel device driver for the board, which will be discussed in some detail. This is my first attempt at writing a Linux device driver. The hardware is exposed to the user via sysfs. Reference usbled.c to get an idea of how this driver is coded. Another part of this work involves hardware add-ons such as an I2C memory chip and a character LCD display, both of which will be demonstrated at the meeting. Yes, we'll see some blinking LEDs, too! Afterwards, we'll talk about the May meeting, and my hope that we can have a PGP key signing party at that meeting. I'm looking for a volunteer or two to run the May meeting, since I don't know how to properly run a PGP key signing. Besides that, I'm hoping to get my passport back from the US Govt. before that meeting (it is being renewed). I'll bring these books for the free raffle: - The Ruby Way - 2nd Edition, Addison-Wesley - Java in a Nutshell, O'Reilly (used) - User Mode Linux, Prentice Hall We should also talk about this summer's WLUG party/BBQ. If there is anybody who lives nearby that would like to host the party, please let me know. (BTW, what ever happened to the pictures from last year?) We'll then adjourn to the Tech Pizza restaurant for food, drink, and good conversation. See ya later, Andy - -- Andy Stewart, Founder Worcester Linux Users' Group (http://www.wlug.org) Chelmsford Linux Meetup Group (http://linux.meetup.com/393) Amateur Radio: KB1OIQ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iD8DBQFGGSVMHl0iXDssISsRAhakAJsGCJppUrc6ApUydyB8ySXWQuHWAgCePvG4 ySP5mx39OBBoOx7u2t7iNE8= =04D0 -----END PGP SIGNATURE-----

Success with my bootless ULTRA1
by ken jones 08 Apr '07

08 Apr '07

Thank you all for your suggestions. The SUN ULTRA1 booted! The screen said, " Welcome to Gentoo Linux LiveCD". The trick was from the "ok" prompt to get the address of the CD reader. This was done using devalias. Then ok> boot /sbus/SUNW, fas@e,8800000/sd@6, 0:f worked! I do not know gentoo at all having cut my teeth on aurora and fedora. This will be an adventure. Thanks again everyone. Ken Jones

ping command expansion
by Chuck Noyes 05 Apr '07

05 Apr '07

Hi All, I want to ping lots and lots of consecutive ip addresses. If I issue ping 192.168.1.{1,2,3}, I get ping 192.168.1.1 192.168.1.2 192.168.1.3 which isn't exactly what I want. How can I issue a "short-hand" ping command, that will expand to ping 192.168.1.1 ping 192.168.1.2 ping 192.168.1.3 etc. TIA, -- -Chuck

My client in MA has the following needs for Linux J2ME consultant(s). This could be one position if the developer can do the architecture as well. Otherwise they will need and architect as well as a developer. If you are qualified and interested, please give me a call or send me an email. 1. Architect key changes to their thin client which is Linux 2.6 based which is being moved over to a mobile device. The key is architecture. Strong documentation, strong embedded Linux (ideally 2.6). Estimated about 3 weeks to do the architecture. 2. Development role will include constructing the framework, defining the API, implementing lower layer (abstraction) interfaces from sockets to application stacks like SIP/RTP, etc. strong C and Linux. Mobile Embedded Linux architect required to perform high level analysis and design work for a project that involves porting an existing thick client to a Linux/Java environment for the mobile industry. Consultant's responsibilities will include: - taking the recommendations from the customer - quickly learning the existing client architecture - identifying and developing the best approach to porting the client - delivering a complete design and porting guide using best practices - remaining available for ad-hoc consultation throughout the stages of the port Successful consultant must have solid experience in embedded Linux, strong knowledge of Java ME(J2ME), experience in designing clients for such environments, and the proven ability to lead a team in the initial design phases of a project. Estimated about 3 mths to do this piece of the project. The development team exists and is ready to begin the porting effort, but needs strong guidance from an experienced, senior architect. Must be able to start soon.

vpn solution
by Michael Long 03 Apr '07

03 Apr '07

I now have a need to setup a vpn to my office network and I have just enough admin skills to be dangerous. I am running opensuse 10.2. Am I better off installing openswan (or some other vpn solution) or purchasing an appliance with a vpn built into it. My main concerns are ease of use and security. I am currently using a linksys router as my firewall and gateway to the internet. Each of my computers inside the network also have there own firewalls. Thanks, Mike

do you just need remote access (shell / email) or do you need a bunch of stuff? while I don't have much expirience w/vpns, tunnelling via ssh handles what I do very well. Add securing it via pub/priv keys and its set. -Eric -----Original Message----- From: Michael Long <mlong(a)datalong.com> Subj: [Wlug] vpn solution Date: Tue Apr 3, 2007 7:21 am Size: 601 bytes To: WLUG <wlug(a)mail.wlug.org> I now have a need to setup a vpn to my office network and I have just enough admin skills to be dangerous.

I wouldn't expect this for a HID device, but since the event* nodes aren't showing anything, who knows... In the kernel, it would be interesting to see what happens if you turn on DEBUG in hid-input.c, which currently contains, #undef DEBUG ... static void hidinput_configure_usage() ... goto ignore; // lots of these gotos! -jamieg ... ignore: #ifdef DEBUG printk("IGNORED\n"); #endif -Jamie
