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 | \__\__,_|\_/\_/ |______________________________________________|

Are there any DLNA/UPnP streaming *clients* for Linux?
by Chris Green 03 May '12

03 May '12

Maybe my multimedia naivete is showing through but I can't find any *clients* for DLNA/UPnP media streaming. I.e. I want to be able to use a laptop (or a desktop) to play music etc. stored on a media server using media server software rather than the file system. -- Chris Green

Forum access--browser problem?
by James Freer 24 Apr '12

24 Apr '12

[xubuntu 10.04..... just two days until 12.04!] I'm hoping someone can advise on what to look for with what seems to be a forum access problem. I belong to a classic car forum which has recently decided to change server and forum software. They claimed the vBulletin was having problems. This i question as the Ubuntu forum as many of you probably use is also vBulletin with 1.8 million members and doesn't seem to have problems. The car group are now using Xenforo - anyone any experience of it? I'm using the Chrome browser which i've found fast and without problems so far. I regularly use forums which have the phpBB, SMF and Invision software without problems and fast as well. The problems; difficulty logging in and logging out (like 3-4 attempts), navigating round the forum is very slow if in fact i can enter a particular thread (when i can another 3-4 attempts are required). Going into Settings then activated a window with a message saying a server problem. It would seem to me [not that much IT expertise!] that there is server problem rather than a browser problem. Emailing the Administrator revealed that he uses linux Mint with Firefox - i thought most likely a problem with linux when other folk are using windows. Could there be a problem with Xubuntu? Chrome problems... well i tried a few of the other browsers earlier today and little difference - so Chrome doesn't seem likely. If Xubuntu what could be the problem because i want to sort it before putting 12.04 on - wrong setting somewhere... he's able to use Mint ok! I know this seems vague but i'd be very grateful if someone could give some pointers to investigate. thanks james

Not everyone has, or wants, a license. Don't know what codecs they use. If they use dirac, I thought that was very experimental a few years ago. Regards, Srdjan

Acer Aspire One can't keep up with audio streaming
by Chris Green 23 Apr '12

23 Apr '12

I have an Acer Aspire One 751h which has a 1.33GHz Intel Atom Z520 CPU. It seems unable to decode radio streams that run at 128k, all BBC radio streams stutter hopelessly whether I use a dedicated application (radiotray) or try listening using iPlayer in Firefox. Running top shows radiotray using around 60% of the CPU with pulseaudio using 10% or so, that doesn't leave much to spare! Do I really need a faster computer to listen to radio on line? I'm pretty sure it's not a bandwidth problem, the on-line BBC iPlayer bandwidth check tells me I have enough bandwidth to play HD television. Are there any audio/radio apps out there which specifically aim at using as little CPU as possible? -- Chris Green

Detecting outgoing SPAM in postfix
by Stuart Bailey 23 Apr '12

Hello, Does anyone know if Postfix can detect outgoing SPAM, or more specifically bulk emails? I think a way to restrict or limit a hosted domain to sending only a few emails per hour would solve my problem.

I took this to e-mail, but it seems still to be turning-up on ALUG - or is that only in my installation of Thunderguts? -- Tony Anson www.girolle.co.uk/

ARM emulation
by Mark Rogers 18 Apr '12

18 Apr '12

I want to play with Linux (inc. maybe Android) on ARM platforms, and figured the Raspberry Pi would be a good target platform, albeit hard to get my hands on right now. Has anyone here played with this who can give me any suggestions as to where I should start? I can see various suggestions on the R.Pi website (QEMU or Scratchbox) so I'm really just asking to seek the benefit of anyones experience here, otherwise I'll pick one of the examples out there and see where it gets me. Separately: I've not done a lot with ARM in the past. How transferable are skills learned (and code written) between ARM platforms? I quite like the look of some of the ARM dev boards you can get on eBay, for example, and I'm sure the range of options will only increase over time, so I don't want to tie myself to the R.Pi any more than I need to at this stage. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Job Vacancy: I'm moving jobs, and am looking for someone to fill my shoes
by Jim Rippon 18 Apr '12

18 Apr '12

Hi all, Let me start by saying I am not a recruiter, this is a genuine attempt to help my employers find a replacement for when I leave for pastures new in June. They are looking for a Network Admin / Linux Systems Admin based in Cambridge. Its working as part of a small local team, responsible for production and office systems in the UK and EMEA and as part of the larger organisation based in two locations in Canada. I can certainly recommend the job, the team are good and there's plenty of interesting work coming down the pipeline to get your teeth into, as well as the possibility of travel to other locations in the organisation as appropriate (for example, I have travelled to FOSDEM in Brussels this year with the company as well as trips to our datacentre and corporate offices). Systems I work on include: * Cisco switching, routing, security, vpn, mpls, vlan, qos * Juniper firewalls (SSG-series), ssl vpn (SA-series) * Sonicwall firewalls * Checkpoint firewalls * Linux (mostly RHEL/CentOS, also some ubuntu/debian) * HP Proliant Servers and storage * HP MSA SAN * NetApp iSCSI SAN * IoMega iSCSI NAS Software I use lots of: * RHEL 5/6, CentOS 5/6 * Puppet * Nagios * Cacti * Rancid * RT Request Tracker * Splunk * MySQL Useful skills: * Network design and security focus * Perl/Bash scripting They are looking for a network and security focus, so any Cisco, juniper, security certifications or experience would be a bonus, as well as any certifications and experience in Linux specifically RedHat. I'm not party to the budget for the position, but would expect it to be fairly competitive and there is the opportunity to join the on-call rota for additional pocket-money (roughly once every 4-5 weeks having 24/7 break-fix on-call responsibility for production systems, not usually too disruptive). If you are interested, or know someone who might be, please get in touch by email and I'll let you have more details and answer any questions that I can. Regards, Jim

"stumbleupon.com"
by Ted.Harding＠wlandres.net 17 Apr '12

Greetings All! I wanted to follow up on the Health and Social Care Bill 2012, and was led to the link: http://www.dh.gov.uk/health/2012/03/royalassent/ When I go to this using Mozilla Iceweasel, I get a brief glimpse of the relevant page, which opens: Health and Social Care Bill gets Royal Assent 27 March 2012 Then the screen goes blank, and the browser hangs forever (i.e. still hung after 20 minutes) with "Read platform.stumbleupon.com" showing at the bottom. This is with Iceweasel 2.0.0.19 on Debian Etch and Iceweasel 3.0.6 on the later Debian Lenny. However, when I tried the same link on Windows Internet Explorer there was no problem. The full page came up, and there was no mention of "stumbleupon". This is on Windows Vista (some years old). I've not had this problem with other sites, including Government websites such as http://www.legislation.gov.uk/ukpga/2012/7/contents/enacted (another link in the Health and Social Care Bill search), so I'm wondering how it came about and what to do about it! Anyone else experiencing similar problems? An6y useful knowledge?
