Re: Asus P5W DH Deluxe mainboard and IDE interfaces
by Barry Samuels 17 Feb '07

17 Feb '07

I've had to have a two day break from this thread because I decided to try my two hard drives on the JMicron interface and the DVD drive on the Intel interface. The mainboard manual says the JMicron interface supports up to 2 devices. The short version of the story is that I ended up with the file systems on both drives comprehensively trashed! Linux is normally very good at recovering from file system errors but it couldn't do anything with these. The long story: After swapping interfaces I booted the machine using a Knoppix v5.1 CD, because I'd need to change device names in a couple of files, but went into the BIOS first. The DVD registered as the first primary drive in the first main menu screen as expected but it seems very odd that once in the BIOS any devices connected to the JMicron interface are not listed anywhere. Drives are set as Master and Slave. They are shown, briefly for about 5 seconds, just before entering the BIOS and it was here that I noticed that only one hard drive was shown after the heading 'HDD:' but the name that followed was just a random collection of letters and numbers, the font was also broken up (characters had gaps in them), and that line of text was flashing. I left the BIOS and continued with the boot into Linux and tried mounting one of the partitions. On seeing the message that 'the filesystem has errors' I didn't go any further but closed down the system. I then swapped the cables back to their original positions and tried to boot but it hung a short way into the process. I decided to swap the primary drive and DVD drive back into my old machine and boot from the same Live CD to examine the hard drive. The contents were basically rubbish! I spent quite a lot of yesterday restoring from tape which, as there is a fair amount of data, was a rather slow business. The tape was up to date as far as early yesterday morning so I lost a couple of unimportant emails but that was it. So I'm not over impressed with the JMicron interface so far. -- Barry Samuels http://www.beenthere-donethat.org.uk The Unofficial Guide to Great Britain

Yes I've seen that but it will boot and run from a Live CD on that interface and I have seen comments from other Linux users about trying to get CD/DVD drives working on that interface. So I'm not sure quite what it means. > Under the Intel IDE interface description it says "Install > devices on this connector (PRI_IDE) first, then install on the > JMicron IDE connector, ...". The Intel interface had the DVD drive on it and the two hard drives on the JMicron so that should satisfy that requirement. It would be useful if I could trace the problem to something that I had done. Then, at least, I would have a satisfactory explanation. -- Barry Samuels http://www.beenthere-donethat.org.uk The Unofficial Guide to Great Britain

Samba / Machintosh issue
by Stuart Bailey 15 Feb '07

15 Feb '07

Hi , I have a customer with a small office network They are running debian on their server, and have a mixture of macs and windows workstations. The server is using samba to shared a number of network drives via SMB. the Windows machines can see and browse all of the workgroup, and all machines / shares within the workgroup. The Macs show nothing when browsing the network, but can mount the shares if the path is entered manually. Also, if I go to the Mac console, smbstatus, smbtree, smbclient and nmblookup all seem to produce the correct results. The macs are not listed in the workgroup. The Macs are running OSX 10.4.8. Is this just a Mac issue, or do I need to configure something special in Samba for this to work? Apparently, it did work before all the machines were switched off for Christmas. I've now exhausted my knowledge of Macs - any help, direction etc would be appreciated. Many thanks, Stuart. -- --------------------------------------- Stuart Bailey BSc (hons) CEng CITP MBCS LinuSoft (Owner) Linux Specialist (0845) 6583563 http://www.linusoft.co.uk ----------------------------------------

Sounds just grand Peter. I will look forward to the talks, should be very interesting and informative. I can see I might be more in tune with my 'puter before long which will be very nice. We do not really get on to be fair. lol Will be good to meet other people who use or have used Fedora because when I get in a muddle, my 'sysadmin' lives in Worcester!

Well, there has been one small meeting so far, before I started publicising the LUG more widely and the five members who attended that one expressed an interesting in having a half-hour or so interactive presentation by a member on whatever topic interested them - how to compile software, build your own kernel, run virtual machines, use an iPod, archive a CD collection etc. However, as there may be lots of new people (hopefully), I think we'll keep it fairly flexible again for this one and just get an idea of what everyone else wants to get out of our LUG too. So, I've said I'll bring along a laptop with some information about using a virtual server under Kubuntu, but we may not get into that. There are also a few other things we need to finalise, but it will be mostly meet & greet. > Although I have been using differing flavours of Red Hat and Fedora > over a fair few years, I would not say I have much experience with the > innards of them.

No problem, Tracy! We have at least one other regular Fedora user and I've used a number of variants of it myself as well ... I'm sure you'll get some new things to try before the meet's over. :) Ooh ... I've just had an idea - maybe we should have a regular Agony Aunt slot in the meeting, for people to tell everyone else what they're stuck with! :) If we get a wiki up and running, I can see that coming in handy with that!

Hey Peter, I am sure no disappointment will occur. I hope that the interest is significant enough for the meetings to continue. Is there any kind of agenda, or will this one be a meet and greet? Although I have been using differing flavours of Red Hat and Fedora over a fair few years, I would not say I have much experience with the innards of them.

Hello All, I am interested in the potential for a Ipswich LUG. I find it impossible to be able to make the Norwich meets, and am a silent member of the Malvern LUG mailing list where a friend is a member. They have very interesting chats and I hoping that the Ipswich meets will be just as interesting.

Asus P5W DH Deluxe mainboard and IDE interfaces
by Barry Samuels 13 Feb '07

13 Feb '07

I have recently changed my mainboard to an Asus P5W DH Deluxe which includes both SATA and IDE interfaces. There are 2 IDE connectors of which one is controlled by an Intel chip and the other by a JMicron chip. I have two IDE hard drives (hda and hdb) both on the same cable and connected to the Intel interface. I also have an IDE DVD Writer connected to the JMicron interface. When Linux (kernel 2.6.20) boots it does not recognise the DVD Writer although I can get Knoppix 5.1 to boot from the DVD drive if I append irqpoll at the boot prompt after which everything seems to work. If I append irqpoll at the normal Linux boot prompt I get 'lost interrupt' messages when the system is starting and it seems to hang. It also lists, in the logs, a device sda which does not exist. There is a SCSI card installed which drives a DAT tape drive but nothing else. There are no SATA devices connected. Is there a way around this JMicron problem (DVD not recognised) or do I have to wait for the JMicron drivers in the kernel to be improved? What is this spurious sda device?

Resonance with Norfolk wavelength
by ted.harding＠nessie.mcc.ac.uk 13 Feb '07

13 Feb '07

Hi Folks, An interesting out-of-region experience for you ... On Sunday I was driving down to London along the A10. As I got further South, the pre-set stations on my car radio (Radio4/Norwich, Radio4/Peterborough, Classic FM, Radio3, even Radio Cambridgeshire, and Radio Norfolk) all got worse and worse. South of the Stevenage-Stansted line they were useless, and I had switched off. Then, stuck in traffic around Wood Green, I thought I'd switch it on again and see if those frequencies would pick up anything in the London area. All failed -- with the exception of the Radio Norfolk frequency (104.4 FM). I picked up, loud and clear, "Resonance104.4FM": http://www.resonancefm.com/index1.htm "Resonance 104.4fm is London's first radio art station, brought to you by London Musicians' Collective." It was intriguing listening, so I switched it on again on the way back, and even sat through an hour of music mixed with talk in a language I didn't recognise, which turned out to be "Rasaa: Iranian program with music, discussion and chat" devised by the "Iranian Community Group". So I tracked the station down when I got home (google on "104.4 FM"). The listings (accessible from the above web site) show the variety of the transmissions. Pity I can't listen on the radio from here -- Radio Norfolk wins, of course -- but I'll be trying their "listen live" resources (Ogg/Real/MP3) when they start transmitting later today. Best wishes to all, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <ted.harding(a)nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 13-Feb-07 Time: 09:58:01 ------------------------------ XFMail ------------------------------

A question about encryption/security
by Eur Ing Chris Green 12 Feb '07

12 Feb '07

If I use the encrypt/decrypt functions in vi (or a vi clone) how secure is the resulting encrypted data likely to be? I know that this encryption is not inherently very secure as it's just a "one-rotor machine designed along the lines of the German Enigma, but with a 256-element rotor". However given that the encrypted file has no clue to indicate that it's encrypted or the algorithm used to encrypt it I think it would actually be rather difficult to decrypt. The potential code breaker has to:- Identify the file as being the one with the required data. Guess the algorithm used to encrypt it. Know the contents (or part of the contents). Am I right in my thinking or does a file encrypted in this way show any clues to how it was created? -- Chris Green
