Samba usershares, symlinks, etc
by Mark Rogers 27 Aug '12

27 Aug '12

If I create a Samba share (eg directly in /etc/samba/smb.conf) I can enable following of symlinks (for just that share) with: follow symlinks = yes wide links = yes unix extensions = no When instead added to a usershare (ie in /var/lib/samba/usershares/myshare) this doesn't seem to work. Indeed, these files seem very "fussy"; just moving lines around or leaving lines commented out (with # or ;) seems to break the share completely. However I can't find them documented anywhere (nor indeed can I find usershare_acl properly documented anywhere). So: Is there a way to have a usershare with the ability to follow symlinks (without globally enabling them, which is what I've done so far)? Is there some documentation I'm missing that explains how these work? I can see why allowing users to enable that functionality may not be wanted, but on the other hand having to enable it globally doesn't seem like the best alternative. Should I just add my share to smb.conf and be done with it?

Attempt to use openvpn client as proxy server
by Jenny Hopkins 26 Aug '12

26 Aug '12

Hullo alug, I've got a computer here at home running debian that gets packages from a remote repository running behind a firewall at work using an openvpn connection. Local address is 192.168.10.6, remote webserver is known as repo.tcl.office. Remote nameserver is 192.168.10.10. Openvpn uses a tunnel of 12.3.3.0. I have a second computer on my internal network, address assigned as 192.168.1.whatever by the dhcp server (192.168.1.2) that i would very much like to be able to access this repository. At the moment all the second computer (a balloon-type board) knows is that it is on the network 192.168.1.0 and that its nameserver is 192.168.1.2...not much use to me at all, especially as the nameserver is not on the openvpn and has no idea about tcl.office. I had a try at assigning a static address on the 12.3.3.0 network to no avail, it couldn't ping the computer here on its tun 12.3.3.6 address. Adding various addresses to /etc/resolv.conf on the balloon make no difference. Is this an impossible mission, or are there any tricks and tools i can be using to make this happen? Running openvpn on the balloon is not an option, alas. Hints gratefully received. Thanks, Jenny

Screen resolution stuck
by Bev Nicolson 23 Aug '12

23 Aug '12

Screen resolution is resolutely stuck at 1024 x 768. Attempting it increase this or decrease it results either in it going awol (higher) or impractically large to deal with (lower). I can't do anything with the auto button the monitor. >From xrandr (I have been googling) : Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192 VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 304mm x 228mm 1280x800 59.8 1280x768 59.9 1024x768 75.1 75.0 70.1* 60.0 832x624 74.6 800x600 72.2 75.0 70.0 60.3 56.2 848x480 60.0 640x480 75.0 72.8 72.8 66.7 60.0 59.9 720x400 70.1 So, people, does this mean a new/another monitor might be an idea? Is there anything else I can try? (Ubuntu 11.04) Bev.

Android updates for cheap tablet
by Mark Rogers 20 Aug '12

20 Aug '12

I have a cheap Android tablet, branded Synapse, I think it's this model although I paid nothing like that for it: http://www.dee-sign.co.uk/products/synapse-tablet-top-spec What are my options for playing with Android versions? I'd like to experiment with (eg) CyanogenMod but haven't done it before; I was thinking it better to risk my cheapo tablet than my Galaxy SII but on the other hand at least the GS2 has been well tested... I believe the tablet is just the same as any number of cheap imported tablets and I don't want it to be stuck on the version it shipped with (albeit that it came with ICS). -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Keyboard and mouse 'crash'
by Bev Nicolson 19 Aug '12

19 Aug '12

Every so often (not too often happily) both keyboard and mouse will stop functioning. It seems to happen most often when I plug a camera or MP3 player in. The only way to get them going again is to switch everything off. (If I touch the off button it will shut down in 60 seconds from the shut down dialogue box.) What I'm wondering is, has anyone here come across this problem and is there another, more permanent, solution to it? I would add that I've never had to install any drivers for any such devices, so I'm pretty confident that's not the issue. [Unbuntu 11.04.] Bev.

Wanted - algorithm for bufferless search for a pattern in a stream
by Chris Green 08 Aug '12

08 Aug '12

I can see how to do this in principle but I can't iron out the details and I'm sure there must be some ready made code for doing it 'out there' on the internet. It's just rather difficult to come up with search terms when I don't know what to call it. To explain in detail I want to search for a (constant) string in a byte stream that I can't rewind and I don't want to use any significant buffer space (the constant string I'm looking for is quite long). So, obviously one reads a byte at a time from the stream to see if it matches the first character of the constant string, if that matches one moves on to the second, etc. When the whole string has been matched then it's found - so far so good. However, when a character *doesn't* match one can't go back up the input stream, *but* we know the previous characters as they're the ones in the constant string that we have matched so far. Thus we can 'wind back' by using the constant string for the number of characters that did match and then continue down the stream. If anyone can follow that rubbish explanation then could they possibly tell me what the algorithm is called and/or point me at some sample code? -- Chris Green
