ULTRA1 Gentoo Install presents a problem

DSL testing
by Keith Wright April 10, 2007

April 10, 2007

After several years of near flawless working, I am starting to have trouble with my DSL connection. A few times per year the modem would lock-up. It was rare enough that I did not worry much, I figured it was due to lightening or cosmic rays. In any case, it was rare enough that I could think of no way to debug it, and there seemed to be no real reason to, the power went out more often than the DSL. Lately it has been happening several times a day, I just got done with a burst of about ten consecutive lock-ups. I will be browsing the web, or something and it will just quit working. Ping of the ISP's nearest computer (by IP addr) does not work. I go to the modem, pull out the power plug, wait a few seconds, plug it in, wait for it to boot up, and it works again until the next time. I complained to the ISP (Speakeasy) and the nice guy there said: > I had a look at your circuit and see a sync at 1536 > kbps Downstream / 384 kbps Upstream with decibel > margins of 2.0 dB Downstream / 17.0 dB Upstream. The > downstream decibel margins are very low and as a > result, your line is incrementing heavy errors. I asked if I could see these numbers myself, so that I could try some re-wiring to see if it made the problem better (or worse). He said: > You won't be able to see real time Layer 2 stats of > your circuit, as this information is accessed from > the DSLAM in the Central Office. But I know I have heard some of you talking about statistics gathering programs for network performance. Does anyone know of a program that might help to see how well a DSL line is working, or other diagnostic tools for this? -- Keith

I'm pretty sure we've never seen any pissing matches on this mailing list. Let's squelch this discussion before it becomes one, shall we? Clint ---- John Spencer <jspencer(a)optimaleng.com> wrote: ============= Keith, Not sure why you felt compelled to be so publicly negative. My personal contact info was on the posting. You could have contacted me directly. Perhaps you had a bad day when you read this and could not resist the temptation to slam someone you don't know. There are any number of factors that could cause a company to revise their needs. One item that I am sure is NOT on that list as you state is "they have no idea what they are doing, but would love to have a consultant to blame". For further clarification, this project always required strong embedded Linux and C skills. They are now hoping to find someone that also has the J2ME, but know that is a difficult skill to find and may have some resources that can chip in and help with that part of the project. It also gives someone the opportunity to pick up some J2ME skills. If anyone, including you Keith, would like to discuss this further, please feel free to give me a call or send me an email directly.

Revised Consulting project - Embedded Linux developer
by John Spencer April 10, 2007

April 10, 2007

My client in MA has the following needs for an embedded Linux/C consultant(s). This could be one position if the developer can do the architecture as well. Otherwise they will need an 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. 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 and C. Any knowledge of Java ME(J2ME) is a plus, 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.

REMINDER: Upcoming WLUG Meeting
by Andy Stewart April 8, 2007

April 8, 2007

-----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.

Success with my bootless ULTRA1
by ken jones April 8, 2007

April 8, 2007

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 April 5, 2007

April 5, 2007

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
