Cant enable DMA
by Ben Whyte 27 Feb '06

27 Feb '06

Hi guys Appreciate all the assistance that anyone can provide. I have an ABIT IG-80 motherboard, which uses an intel 915 chipset. When I do an hdparm -t -T /dev/hda I get the following result /dev/hda: Timing cached reads: 3928 MB in 2.00 seconds = 1963.32 MB/sec Timing buffered disk reads: 8 MB in 3.32 seconds = 2.41 MB/sec Now the drive is a 200gb, pata drive and when I try and activate DMA using hdparm -d1 /dev/hda it comes back with /dev/hda: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) I am using the defualt debian kernel 2.6.15. Any ideas as to why it wont let me activate DMA ? Ben

Once again I try - and fail!
by Barry Samuels 25 Feb '06

25 Feb '06

I had some help from the group a little while ago when I was trying to get my Thinkpad to boot from an external (USB/IDE) drive and, with various peoples' help I finally suceeded. Now I'm trying to do the same thing with a drive from another computer. I'm part way there but during boot I see: pivot_root: No such file or directory /sbin/init: 431: cannot open dev/console: No such file kernel panic: Attempted to kill init! Then the process proceeds with a few more lines about USB and SCSI until: Attached scsi disk sda at scsi1, ... etc Attached scsi generic sg1 at scsi1, ... etc and here it stops. I don't remember seeing these errors on my previous attempt. Any suggestions (in the nicest possible way of course) would be appreciated.

Over the last few years I have ranted over and over at friends and colleagues about how existing LUGS are failing their membership I took the logical next step and formed a LUG for people on the Autistic spectrum or with co-morbid communication and self esteem issues. The Autistic GNU/Linux User Group is open to anybody on the Autistic Spectrum, with other communication or social issues or who wishes to be a friend of people with these problems. Membership is open to anybody using or interested in using a Unix™ like system with particular emphasis on Free and Open Source Software. We have a mailing list where people can geek out and no question or comment is considered off-topic from the uber deep geekery of kernel development to the newbie questions about ls, a wiki for knowledge management and hope to provide a link to local LUGS via our membership so our members can reach out into the wider Linux community and meet like minded people. With the support of mailing lists from lug.org.uk we hope to provide a worldwide virtual LUG with a membership stretching around the glode making visits to events and meetings anywhere in the world an enjoyable experience for people on the spectrum. http://autisticlug.org/ Please forward this message to anybody you think may be interesting in joining the LUG or helping support autistic Linux users when visiting your LUG. cheers sparkes ----- Send discussion replies to main(a)lists.alug.org.uk (Reply-To set) Unsub, change settings via http://lists.alug.org.uk/mailman/listinfo/announce

Icon editor - any ideas?
by Chris Green 24 Feb '06

24 Feb '06

I am looking for a simple icon editor for my Slackware system. The only two Linux icon editors I can find are babygimp (which almost works on my system but I get a perl error when it runs) and kIconEdit which seems to want an ancient version of QT for it to build. Does anyone have any other ideas (like should I just use gimp?). -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

That old SCO chestnut.

I'm sure a lot of us have spent a fair amount of time reading about and discussing this matter, so if you've been living underground and don't know what the heck I'm on about, I shan't recant at length about it - a swift google or a look at http://www.linux.org/news/sco/timeline.html will see you right. So anyway, I expect people have heard about this, but here's some links anyway: http://www.groklaw.net/article.php?story=20060221220214214 http://www.groklaw.net/article.php?story=20060223040825533 Ignoring the unnecessary crowing for a minute, I'm skeptical about how IBM are going to make anything of this, but wouldn't it be marvellous if they did? I'll bet the direct subpoena to MS is nothing more than an empty gesture evidence-wise, but there might just be a chance of catching them by the BayStars. I'm not of the ilk that wring their hands and chant at night over the fate of Microsoft, but I can't help thinking that if their supreme arrogance dropped them in serious guano over a silly legal feint like this, the line of sympathisers would be mighty short.

Convert a photo (.JPG) to an icon - how?
by Chris Green 22 Feb '06

22 Feb '06

This is probably a trivial question, but still.... How can I convert a photograph (probably stored as a JPEG file) to an icon file that I can use as my favicon? It would be useful if, on the way, some sort of tone separation process was available to make it work better as an icon too. -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

Bash script to test serial ports
by Stuart Bailey 22 Feb '06

22 Feb '06

HI, I'm trying to test serial ports using a bash script. Currently I have: DATA="1234567890abcdefghijklmnopqrstuvwxyz" stty -F /dev/ttyS0 ispeed 115200 ospeed 115200 stty -F /dev/ttyS1 ispeed 115200 ospeed 115200 echo -n " Sending data from /dev/ttyS0 to /dev/ttyS1:" ./send_data.sh /dev/ttyS0 $DATA & exec 3</dev/ttyS1 while read -t 2 -u 4 RESULT do if [[ "$RESULT" == "$DATA" ]] then echo " PASSED" else echo " FAILED" fi done I repeat this script for data in the other direction. This seems to work fine if a cable is connected between the two ports, and data transfers are successful. However, if the first time round, but if no cable is connected between ttyS0 and ttyS1, the first test reports FAILED, and then the script hangs. BTW the send_data script is a follows: sleep 1 echo $2 > $1 2>/dev/null I thought the read -t 2 ... should timeout after 2 seconds if no data is received. Any idea why this hangs? Also, is there a better way to test these ports? The system I am trying to test is limited - perl and awk are not installed. Many thanks, Stuart. -- --------------------------------------- Stuart Bailey BSc (hons) CEng CITP MBCS LinuSoft (Proprietor) Linux Specialist (01953) 601294 (07778) 383739 http://www.linusoft.co.uk ----------------------------------------

64bit computing on the cheap
by Wayne Stallwood 20 Feb '06

20 Feb '06

Anybody interested in mucking about with an Alpha box ? I have a spare one now due to an upgrade, AlphaServer 1000 Big unit but not as noisy or power hungry/space heating as it looks. 1GB of RAM, complete with ECC parity modules. 266 Mhz Alpha processor (a bit faster than it sounds) 7 hot swap bays ( a selection of drives will be supplied to go in these, mostly 2.1GB units but I do have at least one 4.3 to go in there) Dat drive (untested) Had it running the Debian alpha port...it can also run OpenVMS (hobby licence is available for free still I think) and Tru64 (again you'll need a licence) or Windows NT (not much point, there are hardly any binaries available) or BSD Unit is currently set to a local (VGA monitor PS2 KB/mouse) console but I can reconfigure for serial console if required. ECU floppy included for hardware configuration and I'll shove in a Ethernet card that Debian understands easily. Any offer considered...otherwise it is going on Ebay Also may have a DSSI disk array/host adaptor and disks, depending on if I get time to wipe them...However these need the Array controllers reconfiguring (which requires a special serial lead) and I have never been able to get the adaptors to play on Debian anyway. Also they are 6x2.1GB which hardly seems worth the effort.

FW: UKUUG Spring Conference 2006 - Durham, 21-23 March
by Alasdair G Kergon 20 Feb '06

20 Feb '06

The UKUUG's annual Large Installation Systems Administration (LISA) conference will take place in Durham from Tuesday 21st to Thursday 23rd March 2006: http://www.ukuug.org/events/spring2006/ This is the UK's only conference aimed specifically at systems and network administrators. It attracts a large number of professionals from sites of all shapes and sizes. As well as the technical talks, the conference provides a friendly environment for delegates to meet, learn, and enjoy lively debate on a host of subjects. The conference itself will be preceded by a full-day tutorial on "Managing Samba 3.0", with core Samba developer Gerald Carter joining us from the US. Delegates then have a choice of two workshops on the first morning of the main conference: "LDAP in depth", or "Firewalling with OpenBSD's PF packet filter". The main conference stream will focus on systems administration: the nuts and bolts of running large computer installations. The keynote will be given by James Youngman, now of Google Inc, who will be giving us the low down on how Google's systems are put together. This year, for the first time, we have almost an entire stream dedicated to a BSD MiniCon, and are pleased to welcome Dru Lavigne who will be joining us from Canada, as well as a number of speakers from the UK BSD community. We hope you will be able to join us in Durham for what is set to be one of our biggest and best conferences of recent years. -- Ray Miller, UKUUG - the UK's Unix and Open Systems User Group http://www.ukuug.org

Wirelessness and XP
by Peter 19 Feb '06

19 Feb '06

Has anyone encountered anything like the following? Start out with a netgear ADSL wireless router, new laptop, XP up to date, and coming into the admin interface of the router through a wired ethernet connection on another computer. Plug in, and the wireless network is recognised immediately. However there is no authentication or security, and it is recommended to change the SSID. I change it, and reboot the device. The old SSID is now shown in XP, along with the new name as a second network. In the admin interface for the router, at the top level, the new name is shown. Further down in the stack, the old name is shown - there are two menus, one where you change the SSID, the other where you allow or don't allow multiple SSIDs. It is in the second one that the old SSID shows up. Delete the old network in XP, and try to use the new one. Can't. Delete all of them in both machines, create a new one on the device. Now no network is visible, though the admin interface says its there, and the wlan light is on. Decide to try creating a new one, on the device. The old one, now supposedly deleted, now appears and can be connected to. What is going on, asks my friend? I spent a couple of hours on this in increasing embarassment, and not understanding at all what was happening. How could it be that networks which the router thought were there should not be visible from XP, and vice versa? Why did rebooting the device not seem to work as you'd expect? The devices by the way were on the same table top, so signal strength wasn't an issue. Was I missing something blindingly obvious? Thought wireless Linux was difficult, but its nothing compared to this! Peter

Could this happen on Linux?
by Ted.Harding＠nessie.mcc.ac.uk 18 Feb '06

18 Feb '06

Hi Folks, I've just been reading a shocking story on R-devel (the developers' mailing list for the R statistical programming language). Quote: "Over on R-help, the old problem of floating point precision has come up again (see my example below, where calling RSiteSearch can change the results of the var() function). The problem here is that on Windows many DLLs set the precision of the fpu to 53 bit mantissas, whereas R normally uses 64 bit mantissas. (Some Microsoft docs refer to these as 64 bit and 80 bit precision respectively, because they count the sign and exponent bits too). When R calls out to the system, if one of these DLLs gets control, it may change the precision and not change it back. This can happen for example in calls to display a file dialog or anything else where a DLL can set a hook; it's very hard to predict." In other words (if I understand aright), certain programs or processes can change the way the CPU functions when doing floating point arithmetic with the result that other programs will subsequently operate in a different FP environment and get different answers. I'd like to think that Linux was immune to this kind of thing, but can't see an a priori refutation of the possibility. What are the informed views on such a question? 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: 18-Feb-06 Time: 16:12:56 ------------------------------ XFMail ------------------------------

Belkin PCI wireless card
by Ian bell 17 Feb '06

17 Feb '06

I am having some trouble configuring a newly acquired belkin wireless network card. I have it working but it is a kludge and I don't know why it works so I would like some advice. I have sorted the kernel module (rt2500.o) and I have added modprobe wlan0 to the end of rc.modules tp load it. It loads ok and I can ifconfig to my heart's content but it won't connect to my wireless router. I ran netconfig to set up dhcp but the client dhcpcd does not seem to get run. Running from the console does nothing but await the timeout. route shows just the local loopback. However, by accident I discovered that if I ran kwifi and configured the card to look for my router in infrastructure mode, then if I run dhcpcd wlan0 everything works. route shows that dhcp has made the necessary connections. OK I can do this manually every time but I don't understand what it is that kwifi is doing. Obviously there is a step I am missing somewhere. Can anyone help? I am running Slackare 10.1 Cheers Ian

Colour lasers
by Barry Samuels 16 Feb '06

16 Feb '06

I want to get a colour laser printer but find the offerings rather confusing. Can anyone recommend one to work with Linux from experience? I want it to be capable of producing good prints from digital photographic images as well as general documents. I know that any Postscript printer should work with Linux but I remember seeing someone on ALUG say don't get one which uses Postscript as a layer over the printer's native language because it makes printing slow. A number of printers describe 'Postscript emulation' or 'Postscript simulation' - is there any difference? Are these the slow ones? Very often it is not clear whether a particular printer is true Postscript or not. What would I have to spend to get a true Postscript printer? Which ones should I avoid? -- Barry Samuels http://www.beenthere-donethat.org.uk The Unofficial Guide to Great Britain

How to become another user, without password, but keep environment?
by Chris Green 16 Feb '06

16 Feb '06

In my role at work at the moment I frequently have to become other users (mostly build management logins rather than specific user logins). To make this easier for myself I put myself in the user's .rhosts file so that I don't have to give the password every time I become the other user. This is inside a small[ish] development group so this doesn't raise any difficult security issues really. However if you 'rlogin -l newuser hostname' you get newuser's environment. This is OK sometimes but often is a bit of a pain because I need to reset DISPLAY to get X applications to work on my screen and I also lose my favourite editor, etc., etc. So is there any way to preserve the environment in the same way that would happen if I did an 'su newuser' but, on the other hand, allow me to login in without entering the password (as I can with rlogin)? I can thing of various nasty scripting ways of doing it but su is so close to what I want it seems a pity to re-invent an almost invented wheel. -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

Firewall routing problems
by Stuart Bailey 16 Feb '06

16 Feb '06

Hi, I have a customer who is try to give me access to some data for testing, on one of their server, port 5000. If I telnet to their port from my server, I can't get a connection, unless I disable my firewall - not something I like to do. If I look at a tcpdump for port 5000, I can see the connection going out to the internet (5000 is enable in my firewall), and I can see that the masquerading ports are in the same range as when I send SMTP or HTTP packets - which work fine. Any ideas what else can be causing the problem? I'm using Guarddog to configure the iptables. Many thanks.

Hosting questions
by Chris Green 15 Feb '06

15 Feb '06

My wife wants to register a set of domains for a small (long term) project she's thinking of starting. I've checked and a nice set of 'same name' domains are available as .com, .co.uk and .biz. The question is should I just register the domains and host them on the home Linux system or can I get a reasonable deal from anywhere for hosting and registration all in one go? Can anyone recommend a single registration company/site which can do all these TLDs at a reasonable price? I've used Just The Names for my isbd.ltd.uk domain and they are reasonably priced for .com and .co.uk but they're expensive for .biz. If I host them on the home system (which already hosts isbd.ltd.uk forwarded from Just The Names) is it possible to 'virtual host' a number of domains even when they're registered with (possibly) different companies? -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

[OT] Fault puzzle
by Ted.Harding＠nessie.mcc.ac.uk 14 Feb '06

14 Feb '06

Hi Folks, Your experience may help here. Today I was phoned by a friend who'd switched on her PC only to get the message "Operating system not found", together with the observation that "DHCP" and "MBA" had come up on screen. The only special circumstance was that the machine had been left unused and switched off for just over a week. So I went round and had a look. Switch on, and enter Setup. Check Boot Order: Floppy, CD-ROM, HDD, Network, and MBA-UNDI. So decided that this was consistent with failing to boot off HDD and proceeding to try booting off the network ("DHCP") which failed (since no network) and then "MBA-UNDI" (whatever that is). So tabbed over to IDE setup to see what whas there, or not. Apparently the HDD and its parameters showed up OK. So quit Setup without saving and let it re-boot. Success: clean boot off HDD. Repeatable -- shut down, switch off, disconnect from mains, re-connect, switch on -> clean re-boot as if nothing had ever happened. Provisionally, therefore, thought that the week's off-time had resulted in the CMOS battery draining, so that it had lost its data which were somehow restored when I went into Setup and poked around. But then it occurred to me that if that were so, then the CMOS clock should have the wrong time (e.g. some hours or days slow). Not so: in fact it was 5 minutes fast. So that seems to not favour my hyptohesis. Leaving me wondering what might really have happened. The only thing I did was have a look inside the Setup and re-boot, not altering a thing. Any ideas? With thanks, and 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-06 Time: 22:00:00 ------------------------------ XFMail ------------------------------

Netmasks and IP addresses for dual homed hosts
by Peter Onion 14 Feb '06

14 Feb '06

All of my boxes have got ethernet AND wireless interfaces and everything works fine, but I want to move to using "zeroconf" networking so I don't have to maintain /etc/hosts files on every machine (or go to the bother of setting up a proper DNS server). I've got the avahi daemon working and nss-mdns is working for resolving ".local" host names. Now seems like a good time to review the way I've allocated IP addresses to hosts. My ADLS modem/ethernet router/WiFi access point is a Dlink DSL-G640T which has the address 192.168.1.1 How would you assign addresses to hosts that have wired and wireless interfaces? BTW at home I normally run with the Wireless interfaces turned off but use them if I take machines "away from home" so I don't have to bother with network cables and hubs etc. However laptops sometimes gets used with wireless interfaces at home.
