'ssh -X' doesn't seem to work, any alternative ways to do the same?
by Chris G 06 Oct '10

06 Oct '10

I'm currently away from home and I'm trying to get a GUI application running on a machine at home with the display here in N. Wales. Normally I would connect from the remote location using 'ssh -X' so that the DISPLAY environment variable would be set up to work through the ssh 'pipe' and a GUI app run on the remote machine (at my house) would use the display on the machine where I'm sitting currently (in North Wales). For some reason (possibly security on intermediate machines, this isn't a single hop ssh connection) the -X parameter in ssh isn't working for me in this case so I'm looking for alternatives. Can anyone suggest alternative ways of achieving my goal? The *real* aim is to allow me to get at my router configuration from here in Wales so I can change it to allow direct ssh access from this IP address. The router's web configuration uses so much bad/arcane javascript that you can't access it using lynx/links/w3m and the telnet access to its configuration is far too difficult to attempt to use remotely, the chances of screwing it up so that access is completely denied are very high. I have full root access to the server machine at home if necessary so can install/configure stuff as necessary, similarly at this end I'm running Linux on the laptop I'm using and can do whatever's needed. Thanks for any help and suggestions. -- Chris Green

fetchmail and MS Exchange 2010
by Mark Rogers 05 Oct '10

05 Oct '10

I can't persuade fetchmail to collect mail from an Exchange server on our LAN (fetchmail and Exchange are both on the LAN). The errors I am getting are: fetchmail: Server CommonName mismatch: myoffice.mydomain.co.uk != 192.168.11.10 fetchmail: Server certificate verification error: unable to get local issuer certificate fetchmail: Server certificate verification error: certificate not trusted fetchmail: Server certificate verification error: unable to verify the first certificate fetchmail: Error exchanging credentials fetchmail: Authorisation failure on user(a)192.168.11.10 fetchmail: Query status=3 (AUTHFAIL) myoffice.mydomain.co.uk resolves to the office's external IP address, although I think (from Googling) that the first line is a warning not the reason for the failure. My fetchmailrc is fairly simple: set daemon 60 set invisible set no bouncemail set no syslog set logfile /var/log/fetchmail.log poll 192.168.11.10 protocol pop3 username "user" password "password" mda "/usr/bin/rt-mailgate --queue general --action correspond --url http://localhost/rt/" no keep You'll see from the last line that I'm trying to set up Request Tracker (RT), and it needs to be able to collect mail from our office mailserver. This guy seems to have the fix: http://berqnet.blogspot.com/2009/11/exchange-2007-fetchmail.html .. but I don't know what he means by "the fingerprint of the Exchange 2007". [We've had nothing but problems like this since moving to Exchange, but it does a reasonable job of keeping Windows users in check so we're stuck with it.] -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Numbered Lists
by Richard Parsons 04 Oct '10

04 Oct '10

Hi folks, I'm trying to choose a good text markup language (e.g. markdown, restructured text etc). I want it to be able to deal with nested numbered lists. So something like this: # Dog # Kitten # Fish # Goldfish # Haddock # Elephant would produce something like this: 1. Dog 2. Kitten 3. Fish 3.1. Goldfish 3.2. Haddock 4. Elephant Anyone know a text format that would fit the bill? Many thanks, Richard

Analogue bonanza
by Anthony Anson 04 Oct '10

04 Oct '10

The PDSA charity shop near the Norwich Bus Station has a table full of pooterbooks, new, but some of them admittedly have whiskers. At first glance there's not a lot which is obviously for Linuxoi, (I've had those innit), but there are piles and piles of useful-looking books on the multitude of programming tools. They've all been reduced from their oiginal prices to three squids, and from there to a pound, nicker, quid or oncer. -- Tony Anson www.girolle.co.uk/

Scanner woe
by Bev Nicolson 04 Oct '10

04 Oct '10

I've taken charge of my first scanner (a freebie from a friend) but I'm having trouble getting it installed. If I go to XSane it says "failed to open device snapscan :libusb:001:002 " . I have since installed every XSane extra there was via synaptic but it's still won't play ball. I'm very reluctant to give in though so how do I investigate what's up? And even more to the point, how do I fix it? It knows it's there I'm sure. [Ubuntu 8.04] Bev.

Computery/Linuxy stuff for sale/free
by Adam Bower 03 Oct '10

03 Oct '10

Hi people, I'm having a bit of a clear out at the moment and have the following for sale/free, all stuff has to be collected from Little Plumstead which is about 5 miles East of Norwich. If you do want something email me offlist. Prices are rough guides to what I want, if you can convince me something is worth less than my guide price then I will quite happily accept it. Classic XBOX softmodded with XBMC = Free. Ok, there's a reason this is free, the dvd drive is sort of broken, it won't open unless you give the xbox a good thump on the top. Of course if you just want to use it as a network media player then this won't be a problem. I CBA to try and fix it, it comes with a controller and a couple of component video leads and the power lead. I no longer have the scart lead for it. This will also run linux if running on a 700Mhz pentium 3 with 64Mb of RAM is your thing. If it isn't claimed by 10th October it's going to the recycling centre. IBM Thinkpad X32 Laptop = £100 My trusty X32, replaced by a newer and faster (but much heavier!) model. This is a 1.8Ghz Pentium-M powered machine with 1GB RAM and a 160GB hard disk. It also has built in wireless lan and bluetooth. Comes complete with 2 power supplies (1 might be a bit temperamental and not always like giving power). 1 Car power kit so you can plug this into the 12V cigar lighter on your car and do your thang. 1 External CD-Rom drive and 1 Tom Bihn "Buzz" sling bag. It also has a Windows XP license key on the bottom and the Windows recovery disks if that's your bucket of biscuits but isn't something I'd recommend! The battery on this is roughly half good, last time I tried I got 2 hours of usage out of it but I won't guarantee that you will get that much out of it, also, it appears that either a thunderfly or bit of dust/dirt has got under part of the screen about 3cm up from the bottom in the middle of the screen and is a couple of mm long which is annoying but cosmetic. Currently this is running Ubuntu 10.04 (or will be when the install finishes). Was my main laptop for some years so almost exclusively ran Linux. Old AMD Athlon XP 2800+ Desktop computer = £70 This is a 2Ghz Barton core AMD Athlon, with 1.5GB RAM and 2 (yes count them 2!) 300GB IDE hard disks. It has a Ge-Force 6600GT 128MB AGP GFX card with extra zalman cooler on it, ASUS A7V8X motheboard, HP Lightscribe DVD Burner all wrapped up in an Antec Sonata 2 case which if you are of the alternate persuasion has a Windows XP license key attached to it so you can use software from the dark side. It also has a rather bling case fan with green leds on it (don't ask how it got there) and a Zalman quiet cpu cooler. At the moment it's not running any OS at all as I ran DBAN over both the disks. I reckon by having a quick look on ebay that if you parted it out and sold all the bits on ebay you could make a profit! Was my main desktop for some years so almost exclusively ran Linux but on retirement was used as my Windows test box. Thanks for reading.

Ignore this question now. It was as Peter suggested. Bev. (Who did check the manual before posting, honest. Sorry if I irritated anyone.)

Problem playing AVI files, they don't play, just stick at first frame
by Chris G 02 Oct '10

02 Oct '10

I seem to have broken something on my system, I'm sure AVI files *used* to play OK. When I try opening them with either mplayer or with totem they just show me the first frame and that's it. With totem I can drag the time slider across and the movie plays so decoding would seem to be OK, it's just that it doesn't play automatically. Any ideas what might be wrong anyone? -- Chris Green

Apache and chrome query oddity
by James Bensley 01 Oct '10

01 Oct '10

Luggers', I hope you are all well. I'm hoping someone out there will know what is wrong with an apache server I have. SSL is up an running, a .htaccess in the web root redirects all incoming http request over https. When someone browses in chrome to http://apache_server the index document (in this case index.php) is parsed to the browser as a download? If I browse to http://index.php I am redirected to https://index.php and it works fine, if I browse to just https://apache_server its fine, but http://apache_server isn't working, chrome just downloads the index page? What could this be, I'm no apache master, could it be a MIME miss-match between browser and server? -- Regards, James. http://www.jamesbensley.co.cc/ There are 10 kinds of people in the world; Those who understand Vigesimal, and J others...?

Unsetting bits using sed or similar?
by Mark Rogers 01 Oct '10

01 Oct '10

Help! I need to go through a text file, and for all lines similar to this: X-Mozilla-Status: 0009 .. I need to unset the 4th bit (so the above becomes 0001). Not all X-Mozilla-Status: lines which have the bit set have status 0009, however. I have 0008, 000b, 0018, and so on. Suggestions? Background: Somehow I managed to delete a load of email in Thunderbird which I need. It ended up in Trash so I moved it back to my Inbox, but for some reason it didn't appear in my Inbox, but did get deleted out of Trash. However by "deleted" I mean it set the 4th bit of the status word, so until I compact the folder I can recover it by unsetting that bit. I still need to work out why it didn't go back into my Inbox, I think I may have discovered a bug there. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG
