flv video issue
by Bev Nicolson 21 Mar '10

21 Mar '10

The problem is this. Whenever I try viewing a .flv video, Firefox crashes. I have, for another issue a while ago, reinstalled flash and that hasn't made any difference to this particular problem. Any ideas? Bev.

help with xinput
by Chris Walker 21 Mar '10

21 Mar '10

Hello, Due to health issues, I am trying to use an Evoluent Vertical Mouse with Mandriva linux. http://www.evoluent.com/vm3.html I'm using KDE as my desktop and have been unsuccessful in mapping the buttons. If you look at the picture in the above URL, you can see that the mouse has 3 buttons and a scroll wheel on the right side. It also has another button on the left side, shown in 'Familiar Grip' as button 5. I'm trying to map what is shown as button 2 as a double-click. I can do it under Windows 7 providing I use some extra software as the mouse isn't supported past XP but despite using xinput under Mandriva like this - xinput set-button-map 6 1 2 3 4 5 6 7 3 9 10 11 12 13, it isn't working as a double click. I also need to map button 5 as a refresh for use in web browsers. I haven't tried that yet as I didn't want Firefox to confuse the issue. I want double-click to work within the desktop. Has anybody done anything similar to this and can point me in the right direction as I'm getting nowhere fast. I also have a special keyboard and want to switch off NumLock at startup as Mandriva is switching that back on but I'll put in another mail for this. TIA. -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:cdw_alug@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

port forwarding wierdness
by mick 20 Mar '10

20 Mar '10

OK - I know this isn't strictly a linux problem (though it may be) but someone here may be able to help, I have an odd problem with port forwarding through a linksys WRT120N router. My network looks like this: outside - Cisco ADSL - DMZ - Linksys - inside The DMZ net is 192.168.1.0/24 inside is 192.168.10.0/24 The DMZ has two debian ARM boxes on it, inside has several different debian/ubuntu boxes, but crucially has my dnsmasq DNS server on 192.168.10.50. That server lists all my local machines. The linksys has NAT turned on. It also allows port forwarding of both TCP and UDP on port 53 from the outside (i.e. the DMZ) to 192.168.10.50. Now the wierd bit. DNS lookups from the DMZ to the inner server through the linksys only work once every 4-5 minutes. So if I fire up nslookup or use dig to resolve any of my internally named servers I can do it immediately, but then get "connection timed out; no servers could be reached" for the next 4 or five minutes whereafter I can again resolve a host. Can someone please suggest what may be going on? Anyone else using a WRT120N? I can't find anything on the obvious forums. (And yes I know I could move the DNS server to the DMZ......)

We're not evil??
by Martin Collins 20 Mar '10

20 Mar '10

Anybody use magnatune for streaming through rhythmbox? See this link: http://blogs.magnatune.com/buckman/2010/03/new-business-model-for-magnatune… This would make magnatune more like spotify. Does this mean free listening is coming to an end? Personally I'm a bit cheesed off with it, as I don't listen enough to make a subscription worthwhile, nor do I have internet access 365 days a year so I wouldn't get what I was paying for. However, I did buy 3 or 4 albums from them a year. Forcing a business model on me, although not evil, certainly isn't angelic! Martin

the problem with lp was the usb parallel converter
by Peter Alcibiades 20 Mar '10

20 Mar '10

Turns out that the problem with using lp must have been the adaptor. Its a parallel printer, and it was being connected through one of those parallel to usb adaptors. With a parallel cable, and redefined as /dev/lp0, it works. The original method of cat > /dev also works on this definition. No idea why, though. I have used those usb adaptors successfully in the past and if it were possible to hit it using cat >/dev, it seems puzzling that lp could not drive it. Should have thought of trying this earlier, but of course, SFF machines now often don't have parallel interfaces. I also now do lprm on starting up the program to clear the queue, just in case.

Skype problem
by Ted.Harding＠manchester.ac.uk 19 Mar '10

19 Mar '10

Hi Folks, Maybe some of you can elucidate a Skype puzzle. I have Skype on Win XP (v. 4.0.0.216) and on Linux (v. 2.0). I usually use the Win XP version because it works better. As of yesterday, I had the same Skype name and password on both. I hadn't used Skype for a couple of months, but yesterday evening started it up in Win XP and entered the password. It hung for several minutes, then came up with a message that it had failed to connect. I repeated this several times (thinking maybe Skype was clogged, or something). Same result. And the same result with the Linux version ("P2P connection failed"). Repeatedly. So I wondered if their might be a password problem, therefore logged in to www.skype.com using it, and got in OK. Nevertheless I decided to reset the password anyway. I was sent a password token to log in to the secure site for doing this, and set about re-entering the old password. Got a message "Password too easy to guess" (also required numbers + letters, which it hadn't done before). So I chose a different password. After that, I had no problems using the Win XP Skype with the new password, but when I tried Linux Skype with the new password it still failed to connect. Re-tested again this morning: Win XP Skype works, Linux Skype does not. One remaining issue might be that the Linux Skype version (2.0) may now be too old to be acceptable to Skype, though that would be surprising. I'm aware that Skype can go real flaky at times (though not very often, in my experience), but the above strikes me as puzzling. Any comments and suggestions welcome. With thanks, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)manchester.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 18-Mar-10 Time: 10:45:14 ------------------------------ XFMail ------------------------------

Another HTML question, again about unwanted space
by Chris G 18 Mar '10

18 Mar '10

I seem to suffer from this all the time, too much space between headers and the things underneath them. ... and I've simplified it down to the following:- I have the following HTML:- <p> Paragraph1 </p> <p> Paragraph2 </p> In the CSS I have:- p { background: blue; padding-bottom: 0; margin-bottom: 0px; margin-top: 0; padding-top: 0; } (The background: blue; is just to prove it's being acted on) ... and there's still a great wide white space between the two paragraphs. How can I get rid of it? -- Chris Green

Ubuntu 9.10 graphics issue
by Mark Rogers 17 Mar '10

17 Mar '10

See screenshot: http://www.more-solutions.co.uk/files/12032010325.JPG I have tried two identical PCs in case the problem is system or video memory. Initially I had the monitor through a KVM, which gave me a lower resolution but usable screen, although with square blocks on the screen where it wasn't updating properly. (I tried to open a terminal window and just got a white box which I could move around but could see nothing in the box.) It was when I bypassed the KVM and rebooted that it identified the screen and gave me a decent resolution login screen followed by the linked screenshot after login. Chipset is Intel 82810E DC-133 (CGC) according to /var/log/messages Suggestions? I'm hoping the screenshot will tell someone exactly what is wrong, but I can't google a screenshot and can't work out how to describe it in words! -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

VCF - Bletchley Hotel / [Ips]: Peter Jennings walk
by samwise 16 Mar '10

16 Mar '10

Following up from last night's discussions, the Peter Jennings ghost walk (which they proudly proclaim has been featured on GMTV!) round Ipswich is on the first Thursday of each month from the Tourist Information Centre, St. Stephens Lane and costs about a fiver, I think. If enough ppl contact me off-list, I'll see if a date can be agreed upon. Also, for those who expressed interest in the Vintage Computer Festival at Bletchley Park, here's the link to the The Campanile Hotel which has a preferential rate for VCF attendees: http://www.tnmoc.org/vcf-gb/hotels.aspx And, who knows, maybe by next month Adam can convince the landlady of McGintys to give us a tour of the tunnels underneath the pub ... ;) Cheers, Peter.

MySQL BETWEEN
by James Bensley 16 Mar '10

16 Mar '10

SELECT blah, blah, blah FROM tblBlah WHERE date_entered BETWEEN '01/01/2010' AND '20/01/2010' This will select records from my table who's date_entered field is from 01/01/2010 and 19/01/2010. This is because the BETWEEN command seems to go UP TO the day specified but not inclusive. So I thought I would just add +1 on to the data submitted from the PHP search page which works just great except for when you put 31 in as the day of the month, (so say we search from 01/01/2010 to 31/01/2010) it makes it into 32 and the querie returns 0 rows. However if I add an IF statement to not increment the day value by 1 if "31" is given as the last day in the query, we then only get results for 01/01/2010 to 30/01/2010. How can I combat this or is there a "proper" way of doing this as mine almost defiantly isn't going to be the best method? -- Regards, James ;) Jonathan Swift - "May you live every day of your life." - http://www.brainyquote.com/quotes/authors/j/jonathan_swift.html

raw printing, yet again
by Peter Alcibiades 16 Mar '10

16 Mar '10

OK, following or trying to follow, Wayne's advice, I am attempting to use lp -d star temprint.txt. to print to a raw printer. It does not work. My user account is in the lp group, the printer is set up as raw in cups, and it is named star. When I do lpstat -P star all the jobs have piled up there one after the other, and can be cleared by lprm. There are no failure messages however. I have tried lp -P star -o raw But it seems to not recognize the raw option and to only expect page numbers. On the other hand, cat temprint > /dev/usb/lp0 works just fine. If you use cat as above, there is a real risk as Wayne pointed out. If the printer is offline, then its true, the application freezes. This is not desirable at all. Though, its a pretty robust printer, so maybe this is a chance I have to take. And maybe I could provide some kind of choice to just turn off the printing command and clear the queue and tell the user to call for assistance. But it is not good at all. Its a disaster waiting to happen. So it would be nice to be able to use lp. But how? And does anyone have any suggestion why it might not be working or what to check? I also cannot figure out, despite much googling, how to test for whether the raw printer is on line and functioning. Nothing I have tried gives any different result if it is powered on or off. Peter

VNC problem
by Torben Stones 12 Mar '10

12 Mar '10

I'm having an interesting but very annoying problem. I have set up xtightvncserver (client) on one machine in listen mode, and then use x11vnc (server) on another machine. I connect the server to the viewer using the -connect argument. This works fine, as I can see the servers desktop on the client box as expected. Now I change my routers firewall rules to forward port 5500 to the client, and then try to connect the server to the client, again using the -connect argument, but this time using my external ip-address. This is where it gets odd. The vnc viewer on the client never seems to get a connection from the server. But if I look at the routers logs I can see that a message was received and matched against the correct firewall rule. I have used ngrep to find out if anything was appearing on port 5500 on the client, and I can see that there is indeed something coming in on port 5500. In ngrep it just appears as user@localhost:~$ sudo ngrep -d wlan1 port 5500 interface: wlan1 (192.168.0.0/255.255.255.0) filter: (ip or ip6) and ( port 5500 ) ### T 192.168.0.2:45401 -> 192.168.0.6:5500 [R] ...... ### T 192.168.0.2:45401 -> 192.168.0.6:5500 [R] ...... All this means to me is that something is appearing on port 5500, but as it isn't connecting then I can only assume that the wrong stuff is coming in. When I just use the internal address then I can see alot more on port 5500 for example the name of the display. Can anyone help me with the next step as I don't know what to do next. Thanks Torben -- You've got a lot of choices in your life. If getting out of bed in the morning is a chore and you're not smiling on a regular basis, try another choice.

OT: GPU fans
by Mark Rogers 12 Mar '10

12 Mar '10

The fan on the cheap PCI-X graphics card in my Linux box is failing. It's a little (40mm I think) fan mounted into the heatsink. Does anyone know if these can be replaced? It may only be a cheap card but it still seems silly having to pay for a new card just because the fan is dying! Or is there any way to rejuvenate a fan? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Recommendations: Linux Small Form Factor PC
by samwise 11 Mar '10

11 Mar '10

Hi, I'm considering building a small form factor PC to live under and output through my HD TV, primarily for running SDL games initially and I expect I'll stick some form of 64-bit Debian on it. I'm thinking a Mini-ITX size would be about right - something that will fit comfortably under the TV, but doesn't need to be too small. I'd like to stick in a pretty big hard drive (> 1 TB) and probably 4GB RAM at least. Graphics wise, I've had issues getting the official Nvidia binary drivers in the repositories working with Debian, but given it's intended use that's probably not reason enough to switch to ATI (binaries direct from Nvidia do work, albeit need manually updating every so often). I'd like it to support 802.11g wi-fi and preferably bluetooth internally (might require the use of a combo wifi/bluetooth internal card), and as many USB connectors on the front as I can get away with (4, 6?). Support for media cards etc. would be a nice bonus too. I've done some reading around but most hardware reviews don't generally cover linux compatibility, so just wondered whether anyone might have recommendations either for suitable PCs or suppliers I could be investigating. Cheers, Peter.

Samba share permissions

I meant to send this to the list but sent it to mark by mistake, sorry! Been lurking for a while so I guess this is hello! > Is there a better way for me to be connecting to the Linux-based server so > that I can access the same files that the Windows users are using through a > mounted share? Yes, the way we do it at work is like this [sharename] force group sambafiles force user sambafiles path = /where/it/is create mask = 0660 directory mask = 0770 writable = yes write list = @users You need to create a user and group called sambafiles that must not be used for anything else, you can control read and write to this share by using groups, all the files will be owned sambafiles:sambafiles which means all users in the allowed groups can read and write. maz

server startup
by Peter Alcibiades 11 Mar '10

11 Mar '10

Thanks to Mick for offline help. Meanwhile, can I ask for help on something which is so simple no-one seems to write about it? I have installed minimal debian, and then added the requisite stuff for nfs and cherokee and SSH. I'm fine with configuring both of them through the command line, and then in the cherokee case login in and using a web browser. Vi or emacs it will never be, but nano is fine. The command line in general is fine. Its just I never set up a server before. The thing I do not know how to do, is have the installation start up with nfs and cherokee at power-on. And I don't understand what the relationship is between the server function and user accounts. So, when I did the minimal install of Debian, I did one user and set up the root password, and also set up a separate home partition without knowing if this is right or wrong. Was that right? The result is two partitions, one about 10G for / and the other with the rest. Presumably the nfs area will be in the rest. But how do I tell it that? When the server starts, I think this is done by putting entries in init.d, yes? When it starts, does it start with a user login? Or is it running with no users logged in? It will be without screen or keyboard, so I am assuming I do SSH to the IP address. And then login as root? Or as the user? Oh dear, this is so basic. Once its done, it will be fine. I can write little scripts and use awk and manage the system from the command line with no problems, so once I know what to do it will be OK, but at the moment am rather peering into the mist. Peter

X authentication issue/question
by Chris G 10 Mar '10

10 Mar '10

I have a headless 'server' system which runs Ubuntu Server. Nearly all of the time I do maintenance, updates, etc. on the command line so it's just a matter of 'ssh server ....' to do what I need to do. However, occasionally, it's nice to use a GUI application to do something. Until now these have always needed root on the server system and the following sequence works OK:- chris$ ssh -X server chris@server:~$ sudo -s [sudo] password for chris: root@server:~# <run GUI program> The trouble is that when I try to do the same for a non-root user on the server system I get:- chris$ ssh -X server chris@server:~$ sudo -s root@server:~# su www-data www-data@server$ sqlitebrowser X11 connection rejected because of wrong authentication. sqlitebrowser: cannot connect to X server localhost:12.0 I have xhost allowing the following:- chris$ xhost access control enabled, only authorized clients can connect NIS:www-data@server NIS:root@server SI:localuser:chris SI:localuser:gdm SI:localuser:root So why can root GUI programs display on my screen while non-root GUI programs can't? I've tried 'xhost +' to allow anyone to connect but I still get the same error. $DISPLAY is correctly carried through the various logins, I've checked that. Also www-data is the same UID on both systems though I don't really see why that would be relevant. OK, I *could* run sqlitebrowser as root (I have tried and it works OK) but I then end up with lots of files having wrong permissions, it would be much nicer if I could run it as www-data. -- Chris Green

Recommend a DNS Provider?
by Greg Thomas 09 Mar '10

09 Mar '10

For a number of years, I've been happy with my hosting provider, 1&1. I've only really got two complaints; a) Lack of IPv6 support. Hopefully that will come in time, and b) They only support 10 sub domains for each DNS domain you have with them. It's the second that looks like it may begin to bite soon. Can anyone recommend a reliable DNS provider that will allow me an order of magnitude more subdomains (*) if I move my DNS to them? TIA, Greg (*) OK, so 20 would probably be enough for the forseeable future, but then I thought we;'d never get near 10 ...

Moving mailboxes
by Chris Walker 08 Mar '10

08 Mar '10

Ive just bought myself a new machine and am wanting to move the mailboxes from this one to the new one. This one runs Mandriva 2010.1 and the new one runs the 64 bit version of it. I use both Sylpheed and Thunderbird on here so need to know how best to do it. Both machines dual boot and I've sort of managed it for Sylpheed under Windows XP and completely for Thunderbird on XP. Half the messages are missing on Sylpheed though and none of the accounts have transferred. I chose Sylpheed for XP as it started life on *nix and to date it's been much more reliable than Pegasus which is what I used before. But I want to avoid the same problem under Linux that I've just encountered under XP -> 7. Any help appreciated.

Vintage Computer Festival at Bletchley Park: 19-20 June 2010
by samwise 08 Mar '10

08 Mar '10

Hi, I don't know if this floats anyone else's boat but just an FYI - there's an event coming up in June at The National Museum of Computing at Bletchley Park. More info here: http://www.tnmoc.org/36/section.aspx/131 First confirmed speaker is Sophie (nee Roger) Wilson, co-designer of the BBC micro and developer of the RISC/ARM processor. I heard Prof. Steven Furber give a good talk last year about the development of the RISC processor so I'm hoping this should be as entertaining. I reckon this one looks quite interesting and more all-round than the usual gaming-type events I've been to so if anyone was considering a trip to Bletchley Park this year (a good place to visit, at any time), it might be worth coinciding it with this event. If you can't get that far but have an interest in old computers, the Centre for Computing History is based in Suffolk and at some point this year, I have intentions of arranging a gathering off-list. If anyone wants in on that, drop me a mail. Peter. Full Disclosure: I know at least one of the guys who's involved on the periphery with the organising of this event, but he's involved more with organising other exhibits like the working Acorn setups e.g. there should be a BBC Domesday Project running; that sort of thing.

Samba share permissions
by Mark Rogers 08 Mar '10

08 Mar '10

I have a Samba share setup thus: [projects] path = /var/flexshare/shares/projects comment = Projects Drive create mask = 664 directory mask = 775 force group = user public = no valid users = @user browseable = yes writeable = yes This has files written to it by a number of users on Windows, and myself from a Linux desktop. When the Windows users create files, they're group writable (ie any of us can modify them), but when I create them nobody else gets write access. I am accessing the share through a cifs mount, as follows: //10.0.0.14/projects /smb/projects cifs credentials=/smb/.credentials,dir_mode=0775,uid=1000,gid=1010 0 0 (word-wrap added for email). Any ideas what is wrong? Something to note is that all users exist on the file server, and if I look at the directory listings in the shares from the file server then files are all owned by <user>.user (eg mark.user) depending who created them (to be clear, the group name is "user", the user name is that who created the file). However, if I list /smb/projects from my local machine, then all files are shown as owned by me (mark.user) regardless of who created them. This isn't a problem in itself, I only mention it in case it is relevant. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG
