Linux RSS/ATOM feed readers... alternatives to liferea ?
by Anthony Hogan 31 Dec '12

31 Dec '12

Hey all, I've been using liferea for awhile to keep up to date with the various feeds I follow. Of late, it's started segfaulting a lot :( .. Has anyone either fixed this behaviour, or is using another feed reader program? Something with a GUI? I've been resisting importing the .opml into Google Reader, but like a lot of things, may have to go in that direction it seems. Anthony

Audio desktops
by Mark Trickett 30 Dec '12

30 Dec '12

Hello All, I am about to set up a USB stick as a bootable Linux installation for someone else who is blind. I am aware of the Adrienne audio desktop that comes with Knoppix, and that there is the Orca screenreader that some here use. I would appreciate any comments, recommendations or other suggestions, along with comments on pitfalls. One consideration is that they cannot use a braille output, they are a diabetic, and the regular pricking the finger to test the glucose levels makes a braille output device impracticable. If there are comments about enabling audio at login, or boot time, and comments about various loaders that might be relevant, that too would be appreciated, this will be my first foray in putting any Linux onto a USB stick. I would not normally consider autologin, but there is reason that it might have merit for this scenario. Regards, Mark Trickett

Anybody want an upgrade to a 50GB PERSONAL (non-business) Box Storage account? I have a new Xperia Sola phone (main phone is S3), check out the promotion here: https://support.box.com/entries/22264368-sony-ericsson-50gb-promotion-faq And more generally here: https://support.box.com/entries/22057282-box-50-gb-promotion-faqs If you create an account, or you already have one, change the password to something unique that you can tell me and I'll use my new device to upgrade your account. You can and should change your password after I've upgraded your storage using the promotion. NB: If you have access to an Xperia phone or other eligible device, you can do this yourself, but the promotion ends on 31st December, 2012.

Bridge mode ADSL modems
by Mark Dods 19 Dec '12

19 Dec '12

I have a Ubuntu server running pppoe through a D-Link DSL-502T in Annexe-M and bridge mode. The DSL 502T seems to have become a bit flakey in that seems to require restarting every week or so, whereas it used to run for months without being touched. So I'm looking for a drop-in replacement, but everything currently available seems to have wireless (which I don't want) and/or I can't confirm they support bridging and Annexe-M. Can anyone suggest a current model modem I could drop in? -- Regards, Mark Dods, VK3ZR madods(a)optusnet.com.au QF22NE

Migrating from hdd to ssd drive
by Daniel Dalton 18 Dec '12

18 Dec '12

Hi everyone, Today I updated my laptop to use an ssd drive. I am using a Samsung 830 series (128 Gb) drive. I've got most things working nicely, but I had a few questions that others who have already done this may be able to assist with: 1. Hibernate has seemed to stop working for me ever since I installed the ssd. I'm fairly sure it worked with the old hard drive, but now if I pm-hibernate, and turn back on the machine, it is just equivalent of shutting down and booting. i.e. my session is not resumed, and I am asked to log in. I have a swap partition, output of free -m is: daniel@Vostro-3350:/tmp$ free -m total used free shared buffers cached Mem: 3947 659 3287 0 35 346 -/+ buffers/cache: 278 3669 Swap: 6143 0 6143 2. What tweaks do people use to prolong ssd life and also improve performance? Currently I have an fstab which looks like this: # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> # / was on /dev/sda2 during installation UUID=ed09c67d-bd34-42be-8f3b-3dfb567ea764 / ext4 errors=remount-ro,discard,noatime 0 0 UUID=9db7ef9e-5298-4400-8b26-cdf9d6ec4168 /home ext4 defaults,discard,noatime 0 0 # swap was on /dev/sda6 during installation UUID=3df92924-3bd3-4292-a635-a78e9e36d9c8 none swap sw 0 0 tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0 (obviously partition table has changed a bit since I moved from a dual booting system on the hdd to just ubuntu on ssd) I've also made a symbolic link from /var/log to /tmp/ which should apparently help reduce writing to the ssd. (apparently the last line of the fstab means /tmp is stored in ram) I've also added this in /etc/default/grub, and ran update-grub: GRUB_CMDLINE_LINUX="elevator=noop" Is there anything else I should do? 3. My last question: I here alignment is important to ensure best performance and again help prolong the life of the ssd. >From what I read using a multiple of 512 for the first block can achieve this. I attempted to do this with fdisk, but to be honest, was not quite sure what I was doing. (I actually just cp -ax /from/hdd* /to/path/ssd for my ubuntu installation, so didn't use the ubuntu install cd to install on the ssd. (so obviously created all partitions manually). Here is my fdisk output: daniel@Vostro-3350:/tmp$ sudo fdisk -l /dev/sda Disk /dev/sda: 128.0 GB, 128035676160 bytes 255 heads, 63 sectors/track, 15566 cylinders, total 250069680 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x3f5f6184 Device Boot Start End Blocks Id System /dev/sda1 * 2048 31459327 15728640 83 Linux /dev/sda2 31459328 44042239 6291456 83 Linux /dev/sda3 44042240 250069679 103013720 83 Linux Are these partitions aligned? If not how can I repair this, (hopefully not by re-installing!) I'm running ubuntu 12.10 as well. Thanks in advance for any help, Dan

Hi Daniel, Yes, I am aware of port forwarding. This website involve with online transaction so I believe the purpose is to hide the actual web server itself as well as resolving issue that experience previously with port forwarding with online transaction.

Apache reverse proxy on Ubuntu
by Theng Ung 17 Dec '12

17 Dec '12

Hi, Just want to ask anyone that know how Apache reverse proxy work. I am trying to understand a setup for a friend. web server running on windows server with internal ip 192.168.1.20. DNS record for www.abcd.com.au with 203.x.x.10. Linux box (Ubuntu) is setup as reverse proxy server with external eth0 with ip 203.x.x.10 and internal eth1 ip 192.168.1.10. Below is the config from /etc/apache2/site-enable <VirtualHost *> ServerName mail.abcd.com.au ServerAlias *.abcd.com.au RewriteEngine on RewriteRule /.* http://www.abcd.com.au/ [R] </VirtualHost> Base on the above config, I unable to understand how Linux able to redirect web client to the internal web server or from webserver back to client browser. /etc/hosts have www.abcd.com.au point to 192.168.1.20.

The other possibility would be a billion 7800 I believe this will work as a modem but comes with a better chipset and is well support by billion. Not the cheapest of routers though. thanks Deano
