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

Adding an exception to iptables on ssh authentication
by Alex Scotton 04 Jan '12

04 Jan '12

Hi All, I rarely post to this list; mainly due to a lack of knowledge... but find the email chains fascinating and very informative. I was hoping you could help me out with a few security adjustments on my home development server running Ubuntu 10.10; I would like to achieve the following setup with iptables and maybe a script in sshd_config? * Accept any connection from within the LAN (192.168.0.*) * Deny All from outside LAN (Except to ports 22, 80, 443, and the range 8000 to 8999) (the above is admittedly easily done with a google search) but my skills cant quite stretch to finding out how to add an exception to iptables for the IP of any authenticated ssh session and on timeout or disconnect remove that exception. I could then allow external developers to develop on a private port range (7000-7999 - as I do internally) by just connecting to ssh with their public key. Is this possible? Festive Tidings Alex

Spare hardware sought!
by Ted.Harding＠wlandres.net 03 Jan '12

03 Jan '12

Greetings Folks! Hoping you had a good Christmas, and wishing you a Happy New Year. I have an old desktop box whose PSU has blown. So I'm looking for a compatible box to which I can transfer the hard drives and PCI cards. Basic requirements: Working AT box with motherboard & CPU, 64MB RAM or more, space for 4 IDE hard drives, PCI slots (for monitor, parallel, ethernet, etc. cards), PS/2 mouse and KB ports. So if any of you shed-stackers has something suitable, I'd be very pleased to hear. Willing to pay a reasonable reward for a suitable box of tricks! Best wishes to all, Ted. ---------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)wlandres.net> Date: 29-Dec-2011 Time: 11:24:50 This message was sent by XFMail ----------------------------------

Anyone want a router?
by David Reynolds 30 Dec '11

30 Dec '11

Hi guys, I have a couple of Linksys routers that I do not need anymore. I have: * Linksys WRT54GL v1.1 * Linksys WRT54GS v1.1 Both have stock linksys firmware but both could run openwrt if desired. I would like £10 (or nearest offer) for each. Anyone interested? (Please note: these are *not* ADSL routers) -- David Reynolds david(a)reynoldsfamily.org.uk

Synaptic with Debian
by Ted.Harding＠wlandres.net 26 Dec '11

26 Dec '11

Greetings All! Hoping you have been enjoying the long weekend, etc. (especially the "etc."). I have a problem starting synaptic on a Debian Lenny. When it starts up, no packages are reported, and then a window opens with the error message: An error occurred The following details are provided: E: Encountered a section with no Package: header E: Problem with MergeList /var/lib/apt/lists/ security.debian.org_dists_lenny_updates_main_binary-i386_Packages E: The package lists or status file could not be parsed or opened. E: _cache->open() failed, please report. When I click to close this window, synaptic then closes. I have had a look at the named file in /var/lib/apt/lists/ which is certainly there, and cannot work out how to fix it. Any suggestions? (And, in case I don't write again in time, Happy New Year).

DVD's
by Bev Nicolson 26 Dec '11

26 Dec '11

So I have two DVD's I'd like to watch. However, computer says: Error mounting: mount: block device /dev/sr0 is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/sr0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so dmesg | tail [ 22.650906] tg3 0000:03:00.0: eth0: Flow control is on for TX and on for RX [ 22.651116] ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready [ 31.408759] EXT4-fs (sda1): re-mounted. Opts: errors=remount-ro,commit=0 [ 32.768019] eth0: no IPv6 routers present [ 37.097846] kbd_keycode: 30 callbacks suppressed [ 37.097851] keyboard: can't emulate rawmode for keycode 240 [ 37.105836] keyboard: can't emulate rawmode for keycode 240 [ 1245.695843] lo: Disabled Privacy Extensions [ 1921.458077] UDF-fs: No anchor found [ 1921.458083] UDF-fs: No partition found (1) Which I guess is because it's trying to boot from it. (Or is that a red herring?) So what do I do? I have googled and not got very far except installing xine which gets me the menu options but can't play the film which is all I wish to do.

Snowboarding On New Year's Day
by Montmorency 23 Dec '11

23 Dec '11

The Norfolk Snowsports club is running an open day on New Years Day, from 2pm to 6pm. I'll be one of the snowboard instructors helping out and number of ALUGers have mentioned to me on IRC and in person that they're keen on the idea of coming down to do a snowboarding taster session. Other activities such as ski-taster sessions (spits) and tubing (rolls eyes) will be happening. Furthermore, the club bar is cheap and has wireless. Booking is unnecessary; cost is £10 for an hour. Spaces on the taster sessions are limited and it's first-come-first-served, so showing up early is sensible. You will want to be wearing long-trousers and long sleeves, and bring a pair of gloves. Details are here: http://www.norfolksnowsports.com/node/3113 And the Norfolk Ski Club is here: http://maps.google.co.uk/maps?q=Norfolk+Snowsports+Club&ll=52.614332,1.3212… Montmorency montmorency(a)ukfsn.org bellphegore(a)nerdshack.com

Running Jenkins on port 80
by Paul Grenyer 23 Dec '11

23 Dec '11

Hi All I have an install of Jenkins on an Ubuntu VM. I want it to run on port 80 rather port 8080 as I want to run a development Tomcat on port 8080. Goolging suggests the only way to do this is to use Apache to redirect from 80 to 8080, but that still leaves Jenkins running on 8080 which doesn't fix my problem. Has anyone solved this? -- Thanks Paul Paul Grenyer e: paul.grenyer(a)gmail.com b: paulgrenyer.blogspot.com t: pjgrenyer
