Device renaming itself
by Dan062 14 Mar '16

14 Mar '16

Hi, Using Ubuntu 12.04: I have a strange situation where a usb drive was initially mounted as /dev/sdb1 to a directory /ut. For several days data read-write to the drive was going just fine. Then suddenly all read-write stopped, with a Input/Output error, and while mount showed that /dev/sd1 was still mounted on /ut. Investigating further I found using blkid that the usb drive was now showing as /dev/sdc1. How can this happen? I first thought, may be the pc rebooted itself after a power failure and the drive got reassigned, but uptime showed it has been on for 49 days since last reboot. The problem only appeared today or yesterday. I can mount /dev/sdc1 elsewhere and everything seem to be still there. So somehow the usb drive got reassigned by itself. Any ideas how/why this happened? Daniel. -- dan062 <dan062(a)yahoo.com.au>

Giveaways and FS: Cubie, Radxa and Raspberry boards
by Toby Corkindale 07 Mar '16

07 Mar '16

I hope this post isn't inappropriate for the mailing list. I have three single-board-computers that I haven't used in ages, and wondered if anyone would like them? All three come with a case. I have an original CubieBoard, free to a good home! Cortex-A8 ARM CPU, 1GB RAM, 4GB NAND flash, HDMI, MicroSD slot, USB, ethernet, SATA. http://docs.cubieboard.org/products/start I have an original Raspberry Pi, free to a good home as well! I have a Radxa Rock: Quad-core ARM CPU, 2GB RAM, USB, ethernet, bluetooth, WiFi, 4GB NAND flash, microSD slot, HDMI, audio out, etc. http://wiki.radxa.com/Rock/specifications The Rock's the most powerful out of the set, and I'm not giving it away for free -- but happy to sell it on pretty cheaply. No postage, collection from Fitzroy, Victoria. -Toby

gsutil -m rsync + Invalid Unicode path encountered error
by Piers Rowan 05 Mar '16

05 Mar '16

I am getting this error: Caught non-retryable exception while listing file:///home/backups/html/: CommandException: Invalid Unicode path encountered (u'/home/backups/499322._425050_.can._R\xe9 sum\xe9 - Jeremy Smith.pdf'). gsutil cannot proceed with such files present. Please remove or rename this file and try again. NOTE: the path printed above replaces the problematic characters with a hex- encoded printable representation. For more details (including how to convert to a gsutil-compatible encoding) see `gsutil help encoding`. The filename is; 499322._425050_.can._Résumé - Jeremy Smith.pdf # convmv -r -f ISO-8859-1 -t UTF-8 499322._425050_.can._Résumé\ -\ Jeremy\ Smith.pdf Skipping, already UTF-8: 499322._425050_.can._Résumé - Jeremy Smith.pdf I am confused here - the convmv says its UTF-8 already but gsutil throws the error. Using the convmv --nosmart flag screws up the file name. Can anyone shed light on this? I have about 1 mil files and I don't want to rename them one by one each time I get an error. Thanks Piers

Email Clients
by Piers Rowan 02 Mar '16

02 Mar '16

Hi there, I currently use Thunderbird and have used Evolution in the past. I have a wish list that I wanted to share with the aim of perhaps finding an alternative. My criticisms with TB: - Changing the UI They added a archive button to some threads and this is on the right of the preview pane tool bar. If this does not show then the delete button is in that location (as the toolbar aligns to the right). So if you are mas deleting email by scanning the pane then the delete button moves each time the archive one is shown. This means that you can to move the mouse (look / read / think) - rather than just deleting email. - Searching for everything It shouldn't be that difficult to have some indexes for sender, sender domain and message prefixes. I would prefer to have a feature to have tabs / quick lists rather than search / sort my entire mailbox each time I wanted a type of message - Tags Highlighting the row in colour is great.....but that only happens when you have focus on the message - otherwise the text only is a different colour. This means if you have a moderate use of tags then you end up with unicorn vomit rainbow text and have to drill down on each message to see the colour of it - which defeats the point of MAKE SURE YOU DO THIS THING IN BOLD RED tags. - Plugins I am sure there is a (valid) comeback that there "is a plugin for that already" or "write your own" [you flatter me :-] but I would like to think that the core of an email client should cover off: - Email - Inbox filters/views/colour tags - Consistent UI - Tasks & Diary ...as core and not as plugins. I get a lot of email across several accounts and perhaps I am being picky. I am interested in hearing if others have similar / opposing feedback and recommendations of configurations / plugins or applications that addresses these issues. Cheers Piers

own address as source address
by Russell Coker 29 Feb '16

29 Feb '16

> xenbr0: received packet on mb0 with own address as source address What's the best way of tracking down the cause of kernel messages like the above? As an aside it's a pity that the kernel doesn't log the source address in question and whether it's IPv4 or IPv6. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

more about server migration
by Russell Coker 25 Feb '16

25 Feb '16

As mentioned in a previous message (which many people on the list probably didn't get) I've just moved the LUV server to a VM in Germany courtesy of Paul Menzel who pays the rent on the physical hardware. We had a few problems along the way with DNS records not updating when I wanted them to and with the wrong IP address being used for outbound mail - which caused some servers to correctly reject mail on the basis of bad SPF. DNS is now correct and has been correct for long enough that I expect most systems won't have old addresses cached any more (Google DNS has had the new values for a while). Andrew has started the process of gaining control over the DNS (which is registered in the names of people who haven't been committee members for a long time). We need to get that done before VPAC turns things off. My current plan is to use 2 servers that I run for LUV DNS secondaries. I've been a LUV member for 20 years and both the servers in question have been running for that long (one of them hasn't even changed it's IP address). I think that will give some assurance that things will keep working. As an aside if anyone knows how to contact the people running russell.linux.org.au and the creativecontingencies.com DNS servers about changing the entries for LUV then please let me know off-list. When running at VPAC the watchdog table in the Drupal database took up 20G of disk space and as it was in the ibdata1 file there was no good option for freeing the space even after deleting most rows. As part of the migration to the new server I dumped all MySQL databases and imported them. That solved the disk space problem and as I now have MySQL configured for a file per InnoDB table I will always be able to OPTIMIZE TABLE if I have that happen again. echo "delete from watchdog where timestamp < unix_timestamp() - 604800;" | mysql luv_drupal The above command is in a cron job to delete the old entries from the watchdog table. It would be good if we could fix the Drupal problem that's causing those entries (but I don't know how to do it or have time to learn). It would also be good if we could configure Drupal to not store millions of rows in that table (it's supposed to automatically delete old rows but doesn't). Assistance from Drupal experts is welcome. One thing I want to do is to convert the server to BTRFS. BTRFS snapshots is the best way of backing things up. Going forward I want to have much better backups of the server. The fact that I can't visit the server room any more makes them much more important as does the fact that data is crossing jurisdictions. I will resend this message tomorrow to make sure everyone gets it. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Amazon / Google + rsync for storage/backup
by Piers Rowan 23 Feb '16

23 Feb '16

Hi there, I am looking at options for backup storage. From reviewing prices storage is quite cheap but I get confused by the mix-'n-match nature of some of the cloud offerings. The alternative is to spin up a VM with out current providers but then cost per GB is large and there are some limits on the VM disk size. I have tried implementations (fuse I believe) of mounting a bucket and using rsync to copy data to is but it was slow and all files and whole files were transferred instead of the changes only - which killed the cost of the exercise because of bandwidth. From a cost / reliability POV I would like to go with a large provider and I would like to avoid spinning up a new VM if a direct rsync service is available. Any ideas? Thanks Piers

Snipe-IT and IUS community repository for CentOS7
by Peter Ross 23 Feb '16

23 Feb '16

Hi all, I am about to install Snipe-IT as an asset management system. The install script would like to enable the IUS community repository. Do you have experience with it? I would like to know about the availability of security updates. How fast can you get an update? Snipe-IT wants to have PHP 5.6 and a few other things from it. I see 5.6.18 packages (the latest 5.6 version available) - so that's a good sign, I think. Using it seems to be the way of least resistance. Although the website states minimal requirements which are fulfilled without the IUS community repository, e.g. PHP 5.4. Any experience and recommendation? Thank you Peter

Ndis wrapper
by Andrew Greig 19 Feb '16

19 Feb '16

I had no idea this would be necessary, but this morning I purchased an Epson MFP, an XP 432. I made this choice because I expected that Epson, which started strong with Linux would still be doing so. But .... no drivers. I searched the CD for a PPD. No luck! So in the back of my mind I heard a quiet memory echo, ndis wrapper. Is that still a viable process? And is it complex? How would I get it to work with the scanner? Gratefully and hopefully Andrew Greig
