January book report: Quantumbooks Waltham
I encourage everyone to buy locally when possible, and I'm pleased to report Quantumbooks is a local vendor worthy of your patronage. Laura and I spent some time at Quantumbooks in Waltham yesterday and I wanted to let you know the store is alive and well. As Tim O'Reilly wrote a couple of years ago [1], you need to buy where you shop. I was concerned when Quantum took over for SoftPro, as the SoftPro staff had set a very high bar of knowledge, courtesy and quality service. Yesterday, I was pleased to find very well stocked shelves (lots and lots more books than my last visit) and a couple of special deals. The sales people were knowledgeable and knew where to find several titles I asked about., and went out of their way to ensure I got the best deal and all the discounts I might get. Keep an eye on their in-store promotions and website [2] for good deals. This week, they had a good-sized pile of O'Reilly hurts - dinged, bent and torn books - at 50% or better off the cover price. I had signed up for their mailing list, though I don't see a link on their web site. It's probably worth the effort to visit the store and get on the list. We got quite a bargain. With the discounts and promotions, we likely met or beat the good deal user group discount O'Reilly extends us directly, and we got to heft the books and browse the titles -- I decided to pass on one title because the book was just too massive for my level of interest. I also picked up several titles because I had heard of them and a bit of browsing proved they were just what I needed.

impromptu web server using netcat
Hi, All... Most of you are probably familiar with the ever useful TCP/IP utility netcat (often /usr/bin/nc). It's real handy for doing quick and easy file transfers, or otherwise tossing bytes about on a network. It runs on most variants of UNIX (including Linux) and there's even a version for Win32. Those of you who have ever tried to transfer a file between 'doze and 'nix know how hard it can be... create and mount a shared folder or samba share, set up an httpd or ftpd, install putty, third-party file transfer websites, AIM file transfer, etc. - all HORRIBLY inelegant AND time-consuming solutions. The win32 port of netcat has been *invaluable* in this kind of situation, allowing simple file transfer between Windows and Linux machines, using one (relatively) simple command and only one small additional executable (nc.exe). You can find a copy of Win32 netcat at: ftp://ftp.dbnet.ece.ntua.gr/pub/users/george/nc.exe or extract the nc.exe file from the tarball at: http://gd.tuwien.ac.at/gnu/gnu-win32/release/netcat/netcat-1.10-2.tar.bz2 Unfortunately, the popular Win32 version of netcat requires a DLL named ast54.dll, which seems to be missing on some versions of XP Professional. Having recently been faced with such a problem, I tried what may seem an insane solution: using netcat to pose as a web server! As it turns out, it's not only possible but also quite simple to create a simple web server using netcat: $ (echo HTTP/1.0 200 OK; echo; echo 'Hello, world!') | nc -l -p 8080 A web browser pointed at port 8080 will then retrieve the content Hello, world! and display it in the browser window like any other web page. This technique can be used to transfer any kind of file (text, binary, tar archive, etc.) and has been confirmed to work with Firefox. Would anyone care to test against IE? Yeah, it's kind of a loopey solution, but it's still relatively simple. Additionally, it requires NO extra software of the target machine - not even netcat. All that's required on the receiving machine is a web browser. Would anyone be up for implementing a netcat server for HTTP PUT? :D ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
Re: impromptu web server using netcat
Slick. Suppose you wanted to download a file using this kind of server onto an IE machine, but the browser kept viewing the file instead of displaying it. You should be able to do this: (echo HTTP/1.0 200 OK; echo 'Content-Disposition: attachment; filename=some_filename.pdf'; echo; cat some_filename.pdf) | nc -l -p 8080 That should force the save as or open dialog.

Re: impromptu web server using netcat
Hi,
Here's a one-line web server command in ruby:
ruby -e require 'webrick';
s=WEBrick::HTTPServer.new(:DocumentRoot=Dir::pwd,:Port=);
trap('INT'){s.shutdown}; s.start
Complements of here:
http://brianellin.com/blog/2006/03/30/one-line-webserver-in-ruby/
Note that the netcat is considerably lighter weight than either the
Python or Ruby intepreters. Also note that there is a nice degree of
elegance in that the NetCat solution serves one file and only one file.
Take it easy,
David Berube

Re: Fw: linux newbie
On 1/12/07, mike miller [EMAIL PROTECTED] wrote: Thanks for everyones help. I've confirmed that the hardware is the Realtek RTL8111/8168B, identified the correct driver, downloaded the tar file and expanded it. When I tried to install it (make clean modules) I got an error (no such file or directory) after the line: Make -C /lib/modules/2.618-1.2798.fc6/build I went to that directory and found a file named build but it was identified as a broken link. First, let's try a shot-in-the-dark: You might try building the driver source as the root user, if you didn't do that already. Normally, the preference is to not run software builds as root, but I've encountered driver kits which expect to be built as root in the past. If that doesn't work: Linux supports the concept of files which are links, or files which point to other files. (Verbosely, symbolic link, or symlink.) Any program which reads or writes a link actually ends up using the target file. (This is kind of like a shortcut in Windows, but more seamless.) It sounds like one of the files used during the drive build is a link which points to something which isn't there. Get to a shell prompt (also called command prompt, terminal, xterm, etc.) and issuing the following commands: cd /lib/modules/2.618-1.2798.fc6 file build The file command should tell us what the build is trying to point to, which might help us deduce what is wrong. For example: $ file foo foo: broken symbolic link to `/no/such/file' $ In the above, I created a bogus link named foo, which pointed to /no/such/file. As you can see, the file command identified it as broken, and indicated where it was pointing. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

On some Windows machines, and many Linux distributions, Python is installed by default these days -- it's often used for setup and configuration of the system, which means that you might have python in a situation where you don't already have netcat (I don't tend to install it on debian machines until I run into a need for it.) So, although netcat may be more lightweight, Python may still be lower setup cost wise. I've never found a machine with Ruby installed and not Python yet though :) Regards, -- Christopher Schmidt Web Developer ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
