Scripting help: deleting old directories
by Mark Rogers 24 Dec '10

24 Dec '10

Is there a simple way to locate directories which only contains files older than a certain date and then remove the directories? I can find old files easily enough, but if a directory has more than one file in it and one of the files is new, then I need to not touch the entire directory. It's only where all the files are old that I want it removed. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Why Do You Use Linux?
by Simon Royal 24 Dec '10

24 Dec '10

Hi As a Mac user for 10 years I often get asked 'why do you use a Mac', actually it is more in a mocking way than anything but it does make you think. When the rest of the computing world is happy to sit in the puddle of Microsoft there are others who strive for something better either via Mac or via Linux. I moved to Mac after years of slogging it with Windows partly because I started working in a design house but partly because I liked the Mac interface - which at the time was pre-OSX. A year or so later OSX came out and I have been through them all. I was also not impressed with the whole Windows experience. I bought a new machine and it was terrible, it didnt even run the OS it came with very well. I started an interest in Linux about 5 years ago - playing with Ubuntu and Vector to name a few but it wasnt until about 18 months ago that I thought about ditching the Mac and moving over full time. However, funds were very tight and I picked up a low end P2 which gave me a good experience of Linux - Ubuntu, Xubuntu, Mint, DSL, Puppy to name some - but the hardware was not up to being used as your main machine. I was also missing the Mac, so picked up an old G3 and that is where I am today. I never returned to the Mac with the one fanboying enthusiasm I had. Financially, I do not have a lot of money to spend on computers - my family has expanded in the last few years and funds are tight. Macs are not cheap, even older ones. I had a new Mac which died after only a few years and I have never climbed back again, scrappling with old G3 and G4 models. I did not want to go down the Microsoft route and with a fair amount of Linux knowledge under my belt decided to jump back into the non-Mac world, bought a ThinkPad (which I am still waiting to arrive) and that is where I am now. So in short, what make me a Linux user. Well, an ex-Mac user with a disgust for Microsoft and a fan of being different and a nerd at heart. So what make you lot a Linux? Why do you decide to walk on the other side of M?

Adam S60 is a great mobile OS. I used it for years until moving to Android. It might be old and clunky, but it is highly integrated and the contextual menus and fantastic.

Looking for simple[ish] drawing program for basic circuit diagrams
by Chris G 23 Dec '10

23 Dec '10

I want to put some simple circuit diagrams on web pages (or at least accessible from web pages) so I'm looking for a drawing program that is either easy to add circuit symbols to or has them already. I was going to use dia but whenever I try to actually use it I don't find it's as easy as it should be, I've Google'd a bit and found xcircuit which is quite a nice program but the mouse/keyboard usage is so non-standard it would take me ages to get used to it. Does anyone have any alternative suggestions or ideas? -- Chris Green

James Great email and yes I did read it all. Linux is just about ready to jump in as a realistic competitor against Windows/Mac for the average user. I like Ubuntu 9 and 10 much better than 8. Im not a KDE fan, but I do like Lxde and some of the lighter ones like openbox. CrunchBang, Mint, Mint LXDE, WattOS, Xubuntu even Puppy are great for older machines. But I find in general Linux requires less heavy hardware than Windows so even a modest P3/P4 can run the latest gnome or kde based offerings. Each OS has its place and it is down to what you do on your machine, the environment you are in and the apps you require that defines your OS of choice, but with more and more things being done online and with developers writing more mainstream apps for Linux your OS is slowly becoming irrelevant. I for one am glad to be going down the steep learning curve of Linux and joining such a welcoming and helpful group again. Simon ----- Original Message ----- From:James Freer To:main@lists.alug.org.uk Subject:Re: [ALUG] Why Do You Use Linux? Good idea this post... be interesting to see where folk are coming from! as they say. 2007 i only had an old machine that could still just about run win98. I was given a couple of P3 1ghz. I was going to put win2k on one of them but after a browse in PC world in Ipswich i thought i'd give Ubuntu (ver 6.10 CD enclosed) a go. I had read about Red hat back in about 2000 but didn't get round to trying it. My father had just died and i found myself coping with my mother who was then diagnosed with Alzheimer's. While i was coping with her (a rather stressful disease to cope with to say the least) i tinkered with linux and read as much as i could. I could run all the applications i wanted to in linux apart from a mind mapping app, autocad, turbocad and a scanner. Most of the applications better than a doze equivalent although i'd used OO, Thunderbird and other common ones. But i also wanted to know more about linux. It seemed to me that unix in late 80s and early 90s didn't see the potential of the mini or home PC - microsoft jumped in there. What i liked was the cli - made almost redundant by microsoft and yet very much at the heart of the earlier windows. I have a liking for the simple but effective things in life - like my seven classic cars... there's nothing i can't do on them - can't do a lot on modern vehicles. On linux i enjoy the mix of graphical and cli. To me it's not either or - each have their place e.g. i like llgal (cli) for photo albums [http://jessejazza.110mb.com/photos/dogs/best-09/index.html] but i'll stay with graphical text editors. I got a better machine later and ran ubuntu 8.04 (tried the 9's and 10's and weren't to my liking), and have just bought my first new machine. I'm tinkering at present with what distro to use for a while as i've decided to move on from ubuntu. I'm also GOING TO do a Gentoo, slackware or LFS installation in the New Year - i've been promising to do this ever since i started using linux and still haven't got round to it. The linux 'MUST DO' they say 'then you'll know linux' - yet i've failed to get round to it so far. Perhaps it's worth a mention: what's the future of linux? Linux has certainly come into it's own for websites due to the security. Windows holds it's place in the market for office use and at home. Too many distros i feel give linux a bad name and a fair number produce more than the main three desktops. Yes; linux is about choice but i also wonder about the long term of too much choice. Ubuntu is produced in so many forms now and yet the project is still in the red... and that can't continue for much longer. Do i donate; yes to releases that don't have problems. The three distros i've tried where i feel they have gone the extra mile are Pclos, Mint and Mepis yet these are one-man-bands. But each distro i've tried i find there are things i like and then things i don't. Mepis (kde) ran nicely and faster than ubuntu on the P3 - Mepis gets first place for kde imo. Pclos have taken a step that i feel is significant for the future - 'mini' releases. [This Texstar fellow intrigues me... seems full of new ideas - e.g. in pclos before you can use synaptic (i think there the only rpm distro using APT) one runs a speed test and thus select the fastest download server (don't think anyone else does that)]. The basics are on the CD and you add your selection. With ubuntu i'd remove evolution and a lot of stuff i didn't like and put on Thunderbird and so on. So why don't distros save themselves development time and use mini versions for releases? Another development taking place it seems is the replacement for gnome. Gnome is hard to package (apparently) - slackware have dropped it and as other distros seem to be developing xfce maybe we'll be left with xfce and kde. xfce i gather sits on gnome partly and there's also standalone xfce on some distros. But then again certain distros seem to be keen to develop enlightenment, openbox, lxde - lighter versions for older machines! The majority of users probably have a dual core machine - perhaps the next generation of machines are going to be much more expensive! Currently computers are very cheap compared with what they were a decade ago. Quality certainly down - the motherboard on my old compaq P3 is vastly superior in my view. Bit like a landrover compared with a car - all rugged and reliable. Anyway rant over - got to ice the Christmas cake. james On 22 December 2010 14:59, Mark Rogers <mark(a)quarella.co.uk> wrote: > On 22/12/10 14:24, mick wrote: >> >> Don't get me wrong, I'm not naive enough to think that "linux is >> inherently more secure than windows", nor am I blind to the problems of >> application level exploits running in that universal firewall bypass we >> all love (i.e the browser, which to make things even worse may run >> flash).

Alternatives to SMTP when the network fails
by Mark Rogers 19 Dec '10

19 Dec '10

Can't think of a good subject for this, sorry! I have a customer with an ADSL line and direct delivery of email via SMTP to their external IP (into Exchange). The MX record for the domain points to one of my servers running Postfix, which basically forwards mail to their IP if it is up. So far so good.... However, they've just suffered a BT-inflicted ADSL outage that's lasted several days and they want to have a backup for the future. They're going down the 3G backup route (using a router which falls over from ADSL to 3G), but this will give them a dynamic IP when on 3G and, more importantly, we've found out the hard way that in general 3G providers do not allow us to make incoming connections (whether on port 25 or any other). So, my question is: what is the best solution to this? I have come up with several options: - Move the email to POP3 delivery, ie mail ends up in a POP3 mailbox on my server, they collect periodically from that box. From experience this causes problems with Exchange, although I don't recall what exactly. - Provide some kind of POP3/IMAP access to the Postfix mailqueue, so in normal use mail comes via SMTP, but when they switch to 3G they can access the mailqueue (using POP3 or IMAP, and then by extension via webmail) as a temporary measure, with the mail coming in via SMTP as normal once the connection is restored. However, I have no idea if this is even possible? - Drop everything to a POP3 mailbox on the server, but configure fetchmail to deliver it to them via SMTP if the connection is up. Sort of half-way between the two above options. - Setup a VPN between the mail server and the exchange server, and deliver to the VPN address. This seems like the "best" option although I have no idea whether it is practical having never tried it. I'd assume OpenVPN as the best VPN solution? I also don't know how well it would scale if I want to then do this with lots of other sites? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG
