Networking Linux to MS Windows through ethernet
by Robert Stelmack 23 Sep '02

23 Sep '02

First, I am a newbie, I do read the have search the ALUG mail postings, I have RTFM (in fact, I have read way too many FM's) and I just can't get a network between my Linux and Window/98 machine to work to share files. I have to admit that I have tried many things and may have created my own problem, but I want to learn how to fix it without starting from scratch (although, if necessary, I will). When running the SAMBA configurator, under KDE is get the Konqueror message: "Could not connect to host 127.0.0.1 (port 901). I have a Dell 233mhz, Pentium II, Optiplex GXA, with several "on-(mother)board" features: sound, video, ethernet, and USB. The sound, video, and USB function perfectly. I have also attempted to install a second ethernet card and it is physically installed and I did the software changes that one of the HOW-Tos described, but I'm not sure if it was correct, since ifconfig doesn't show it. I have a link below for details. Any help would be greatly appreciated, since I am trying to convince my management to change over from the MS products to the open systems GPL products. Thanks in advance, Cheers, Robert Stelmack Wellingore, Lincolnshire, UK Email (h): stelmack(a)nwlink.com Email (w): robert.h.stelmack(a)boeing.com In order to keep this email message small, I have provided a link (http://e-simassist.com/linux/samba.txt ) to a text file that contains the following: FILE: /etc/samba/sam.conf FILE: running the command testparm /etc/samba/smb.conf FILE: /etc/services FILE: running to command ifconfig

Weekly IRC reminder
by Neill Newman 23 Sep '02

23 Sep '02

This is the automated ALUG IRC meeting reminder sent to remind you that there is an IRC meeting tonight (Monday) at 8.00pm. The meeting takes place on the irc server irc.alug.org.uk in the #alug channel. Most IRC clients should allow you to get there with the commands "/server irc.alug.org.uk" and "/join #alug". Popular IRC clients include tkirc, bitchx, xchat and EPIC on Unix, and Mirc under windows. Here are some links to help you get started with irc. Unix http://www.xchat.org/ http://freshmeat.net/ http://www.epicsol.org/ Windows http://www.mirc.com (loads of help with irc for newbies!)

This is considered ( quite rightly ) to be the safest default option that will operate properly across all PC architecture hardware. The old timers may remember the war that IBM fought to keep their PC hardware and firmware (BIOS) proprietary - forcing competitors making clone machines to do "clean room" BIOs coding and design their own hardware, too. Gaining a cost and time to market advantage for IBM for quite a while. It guaranteed a lot of flaky hardware designs, too. ( Remember the Amstrad 286 HD fiasco? ) Compaq were established in this era; and never quit designing their own hardware. Even today, when it is no longer necessary, or desirable, to deviate too far from accepted "industry standards". They were beginning to get wise to the fact that it is no longer desirable! Two decades later... Only to be swallowed by HP. Go figure. It is cheaper to use "industry standard" chipsets from a third party than to re-invent complex hardware, in the design process. Some big corporations just failed to adapt, and tried to lock in customers to their particular hardware, when the game had moved on to proprietary lock-ins via software: EULAs and proprietary protocols "embracing and extending" open standards. I can pretty much guarantee data loss ( or total operating system loss ) on *any* Compaq where you attempt to force an OS to use DMA when it is not selected by the default install. Quite a few laptop clones are like the Compaq ( I had a Twinheed one just a few weeks ago ). Desktop PCs can also be found with iffy DMA hardware design. Beware the data corruption bug when shifting large quantities of data between IDE ports on some chipsets, too. ( One range of SiS chipsets suffered from this AFAIR ) Although IDE is a blocking type device, the DMA behaviour can also vary from a single device per IDE port to multiple devices daisy-chained on one IDE port. Had I decided to use a cheaper IDE CD Burner on my SiS chipset Desktop ( 2001 Motherboard design ) I'd have walked right into the data corruption problem! ( I prefer to have at least two separate hardware disk channels, one of them SCSI, for best VM performance, anyway. ). TESTING: If you multiboot with Windows 9x ( perhaps to use Office 97 from Wine ) it is easy to test. Make sure that the Windows boot comes to a real DOS prompt, so you have to start Windows with WIN at the prompt ( edit MSDOS.SYS ). Make COPIES of the registry SYSTEM.D* and USER.D* files! Then - in windows, play with the DMA enables for the IDE Harddrive and CDROM. When windows fails to load you have an answer... ( Restore the registry files, and it should be OK ). I haven't known this to corrupt data on the drive, but I'm not making any promises. The worst that usually happens is that it fails to load the "DOS extender" <*grin*> Try this with Linux, and you will probably trash the filesystem. A disposable Windows test multiboot can be a less shattering test option to determine if your machine has well behaved DMA hardware! But there are no guarantees if you start tweaking hardware related stuff. ( Overclocking is another example ). Eventually, you will reach a point where the probability of a timing error will corrupt data, as timing margins are reduced. Consider that slower disk performance means a higher safety margin against data corruption. The size of IDE hard drives now is such that there is a reasonable statistical likelihood of hitting random data corruption, anyway. -- James To reply by private email DONT delete the "nospam" in Reply To or From header addresses!

Fwd: Re: [Alug] Speedtouch Modem
by Wayne Stallwood 21 Sep '02

21 Sep '02

I am using the same firmware for both XP and Linux, But that's a good point I'll try some different versions, I'd completely forgotten about the Firmware I've been updating the sourceforge drivers everytime a new version becomes available, but I've never changed the firmware...Doh Thanks I'll give that a go. Given the time I've spent mucking about with this I really should just go out and buy an ADSL Router, but it's become personal now :o) anyway a Router is a waste at home as I only have one machine here. If lots of other people were having this problem I'd just accept that the Alcatel Modem doesn't work very well under Linux and purchase another solution, but seeing as everyone else seems happy with the speedtouch drivers I've GOT to get it working otherwise it's beaten me. and I don't like losing...........

Dlink quad ethernet card
by Raphael Mankin 19 Sep '02

19 Sep '02

I have been playing with a Dlink DFE580TX quad ethernet card. I have used it in both 2.4.x and 2.2.19 kernels and it works a treat. We have got a batch of them at work, and they are now down to a price where they are affordable for the largish home network. Mind you, 4 single cards are still cheaper than one quad, but you save 3 PCI slots. You have to get the latest 'sundance' drivers from http://www.scyld.com/network/sundance.html. Don't use the one with the 2.4 kernel tree. -- Nothing propinx like propinquity. Mark Twain Raphael Mankin E-Mail: raph(a)panache.demon.co.uk ----------------------------------

I have just borrowed a Dlink DFE-580TX quad ethernet card from the office where we are expermienting with them. We have now tested them on both 2.4.x and 2.2.19 kernels and they work a treat. You can run the four ports independently or as one extra wide-band channel. The driver modules you need are pci-scan.o and sundance.o. The latest versions can be downloaded from www.scyld.com -- Nothing propinx like propinquity. Mark Twain Raphael Mankin E-Mail: raph(a)panache.demon.co.uk ----------------------------------

tar and gzip
by Jenny_Hopkins＠toby-churchill.com 19 Sep '02

Hullo list, When a directory is tarred and gzipped, will it also include any symlinked directories? e.g first directory to be gzipped is /home/jenny, which contains a link to /var/www second directory to be gzipped is /var/www Tarball is created from both these directories. Burning Q: are the files in /var/www being saved in the tarball twice? Jen.

You should only see the >symlink entry not the data the symlink points to. Thanks for that. I severely need to clean out my home directory in that case. Jen
