Renaming of files failing
by Chris Walker 17 Dec '12

17 Dec '12

I have a directory full of files and sub-directories which I've pulled from an emulator. But it has extra filename extensions on it. I would like to traverse this directory, stripping off the extensions and so I've been trying to write a script to do it but it's failing. An example of a file is this :- lamborghini miura_1024.jpg,c85 and so there, I'd like to remove the ,c85. But a bigger problem is where I have the odd file which has a numeric extensions such as .;1 and that's where I struggle. How do I do a substitution in my script to cope with things like that? I've been reading things like this - http://www.cyberciti.biz/tips/renaming-multiple-files-at-a-shell-prompt.html and http://www.unix.com/answers-frequently-asked-questions/13774-unix-tutorials… but I'm still struggling. Can somebody point me in the right direction please, even if it's towards the door ;-) -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:cdw_alug@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

apt-get problems
by Greg Thomas 16 Sep '12

16 Sep '12

I just tried upgrading from Ubuntu 10.04 to 12.04.1 (i.e. from LTS to LTS). It failed. The error message I'm getting is: An unresolvable problem occurred while calculating the upgrade: The package 'update-manager-kde' is marked for removal but it is in the removal blacklist. Google suggests that "apt-get remove update-manager-kde" should fix it [1], but that's giving me the following; Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies. libasound2: Breaks: libasound2-plugins (< 1.0.24) but 1.0.22-0ubuntu6 is to be installed libglib2.0-0: Breaks: gnome-control-center (< 1:3) but 1:2.30.1-0ubuntu2 is to be installed Breaks: gvfs (< 1.8) but 1.6.1-0ubuntu1build1 is to be installed libgnome-keyring0: Breaks: gnome-keyring (< 3.0) but 2.92.92.is.2.30.3-0ubuntu1.1 is to be installed libpango1.0-0: Breaks: plymouth (< 0.8.2-2ubuntu19) but 0.8.2-2ubuntu2.2 is to be installed ppp: Breaks: network-manager (<= 0.8.0.999-1) but 0.8-0ubuntu3.3 is to be installed Breaks: network-manager-pptp (<= 0.8.0.999-1) but 0.8-0ubuntu3 is to be installed E: Broken packages Have I completely hosed my setup, and is a fresh re-install due? Or is there a way around this? Thanks, Greg [1] http://www.hoaglun.com/blog/2011/5/8/ubuntu-1010-1104-upgrade.html

Using Android phone as dial-up modem
by Mark Rogers 29 Aug '12

29 Aug '12

Situation: PC running pcAnywhere, accessible via dial-up (you know that thing we used to use before broadband? :-) At present I have to be sat in my office (or somewhere with a phone line), using a laptop with a modem in it, to dial in to site (the site does not have Internet access). Can I use my Android mobile (Galaxy SII) as a traditional modem, eg via USB connection to PC? PC would ideally be Linux but I have pcAnywhere installed on both.

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? [Ubuntu 12.10 alpha, although I'm sure I've had this problem before on older versions.] -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

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.
