Re: Disabling Debian/Ubuntu apt archives

I am using ZFS for a package repository which is mounted inside the jail or host system I want to upgrade (it's part of a script which can do that on the fly for all jails+host when needed) Transfer between hosts happens via zfs send/receive. Having one mountpoint at the time solves the "two at the time" problem - and scripting others (e.g. the right repository for the right system). I can imagine similar usage when using Linux and btrfs.

Disabling/bypassing UUID on Ubuntu Trusty
by Carl Turney 30 Apr '14

30 Apr '14

Hi All, Want to disable UUID, and address hardware directly by device and partition specs. Did it on my current system (~ 4 years ago), happy. But see differences in files/contents in Trusty, and want your expert advice, before I start changing things. My knowledge is low. (Barely understand what I'm writing.) Can follow clear simple step-by-step instructions, or grateful for links to same. New system is Gigabyte MB, IntelCore i5 CPU, SATA HDD, dual booting on 64-bit Windoze plus just-released Trusty 64-bit Desktop. Here's what I =would= do... (1) Edit /etc/default/grub to remove the # at the start of line... #GRUB_DISABLE_LINUX_UUID="true" (2) Edit /usr/share/grub/grub-mkconfig_lib to comment out the 3 lines starting... if FS_UUID= (etc.) ... but that line doesn't exist in that file. (3) Edit /etc/fstab and change very instance of UUID= (etc.) into the corresponding drive and partition e.g. /dev/sda2 (4) Edit /etc/initramfs-tools/conf.d/resume and change UUID=RESUME= (etc.) into the corresponding drive and partition e.g. /dev/sda2 (5) Run update-grub (6) Then re-do all the above each time I do a kernel upgrade. So please: Your advice, keeping to my original goal of disabling/bypassing UUID. What am I forgetting? What am I doing wrong? Thanks VERY much, Carl Turney Bayswater, Vic

python-iview
by Russell Coker 29 Apr '14

29 Apr '14

Recently python-iview stopped working because the ABC apparently started sending unicode characters where the previous code didn't work. The new python-iview in GIT depends on Version 3+ of Python and the Debian/Wheezy Python build system doesn't seem designed for building that - or at least it's well beyong my Python coding ability. I used the below patch to convert the text in question to plain ASCII and make the program work again (the change to the #! line isn't needed). Note that the ABC doesn't want us to create archives of programs downloaded from their web site. But if you do want to create such archives I can recommend a BTRFS RAID-1 array of two cheap SATA disks for that purpose. 3TB SATA disks are dirt cheap nowadays. The worst of the BTRFS problems I described in my last LUV talk only occur when a filesystem is filled and a 3TB RAID array isn't something you'll fill quickly. --- a/iview-cli +++ b/iview-cli @@ -1,9 +1,10 @@ -#!/usr/bin/env python +#!/usr/bin/python from __future__ import print_function import sys, os, getopt import os.path import iview.config +import codecs try: import configparser as ConfigParser # Python 3 @@ -80,7 +81,7 @@ def print_series_items(items, indent=''): url = item['livestream'] else: url = item['url'] - print(indent + item['title'] + '\t(' + url + ')') + print(indent + item['title'].encode('ascii', 'ignore') + '\t(' def print_auth(): config() -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Hi all, I bought a Firefox phone.. and it does not connect to the Telstra network (Optus works, btw, but I have a Telstra contract at the moment). It works using WLAN. However, I wanted to play with it anyway.. Do you know a way to connect it to a PABX as Asterisk? Regards Peter

Linux PPPoE bridge mode issues - again
by Toby Corkindale 29 Apr '14

29 Apr '14

Hi, I posted last year about a problem I was having with Linux's PPPoE functionality in regards to a specific modem. At the time I put it down to a dodgy modem and moved on, but now I've hit it on another modem, and twice seems more than coincidence. The problem is that path MTU detection seem to break when the "bad" modems are involved. So the Linux box running pppoe is OK, because it knows the interface has an mtu+mru of 1492, but masqueraded clients do not. You can work around the problem a bit, by having an iptables rule with --clamp-mss-to-pmtu, but it's a kludge.. and importantly, only required for two of these four modems. The other two work just fine *with apparently identical configurations* (ie. LLC / bridged) Can anyone think of a reason for this? The rp-pppoe and other mailing lists offer tantalising hints that I'm not alone, but sadly those threads do not lead to any solutions. Modems that work: * TP-Link TD-8817 (Trendchip chipset) * Billion 7300RA (Trendchip chipset) Modems that don't work: * TP-Link TD-8840T (Trendchip) * Billion 7800NL (Broadcom chipset)

crash on netgear readynas
by James Harper 28 Apr '14

28 Apr '14

We have a few Netgear ReadyNAS 104's, and they all crash under high iscsi load. They are being used to hold backups from a windows server, and the one I've been working on rarely gets through a single overnight backup. I have ssh'd in and it seems that the iscsi backing store is a file sitting on a btrfs mount. The kernel is 3.0.101, which strikes me as a little old for running btrfs although I guess being an appliance they could well have backported everything from a newer more stable release. Or not, going on how much crashing it's doing. I was planning on using netconsole to see if I could capture its dying gasp, but it's not compiled in and not built as a module. A warranty claim is the obvious answer, but that's always a pain so I'm wondering if it's possible to work around the problem by tweaking some things. Netgear are aware of the problem, and have asked things like how full is it getting so I guess they know about the btrfs limitations relating to running out of space. So far the only solution they have offered is to try the latest beta kernel and do yet another factory reset, which we've done. Some info (abridged): # mount /dev/md127 on /data type btrfs (rw,noatime,nodiratime,nodatasum,space_cache) /dev/md127 on /apps type btrfs (rw,noatime,nodiratime,nodatasum,space_cache) /dev/md127 on /home type btrfs (rw,noatime,nodiratime,nodatasum,space_cache) # uname -a Linux RPCV-NAS1 3.0.101.RN_ARM.1 #1 Thu Mar 6 09:31:05 PST 2014 armv7l GNU/Linux Any hints appreciated! Thanks James

The 3:1 price difference between HP and ASUS >doesn't surprise much, since that's usually the cost of the name plate. From the beginning (many years ago) I have had problems with some DVD drives not reading video DVD's correctly so these days I usually have 2 DVD drives, and LG and either a HP or Pioneer DVD, if the disk wont work on one it will (usually) work on the other. Note: I do not have a TV or infact watch TV at all, I do though uses DVD's for some entertainment, because of this it was worth my while to go to some effort to watch DVD's. Robin Humble said... >region free firmware is the main stumbling block for me. I lived >overseas for quite a while, so I need to play region 1 as well as >region 4 discs. some uk discs too. errrrrrrrrr, lets put it this way......... libdvdcss allows one to watch DVD's from different regions, its a cryptographic cracking system so some distro's (Debian any way) do not package it. For a long time I have sucessfully viewed zone 1, 3 and 4 DVD's using this library. The library is transparent in use if its present a player (eg xine) will use it, if its not present it will of course not use it. Lindsay

Can you upgrade from official Debian repositories? (Info for other distributions would be welcomed too). Thanks Peter
