Problem connecting a USB HD dock
by GianPiero Puccioni 12 Oct '18

12 Oct '18

Hi, I have two Manhattan "SATA Quick Dock" that I use for backup on HD and I used them without any problem before many times, but yesterday I tried and they are not seen anymore. When I connect the USB there is no reaction and "dmesg" doesn't show any attempt to connect to it, this on two machines (one F27 the other F28). The USB port seems fine as I can connect a memory stick, and the docking stations and HD are working as one of the machine has an e-SATA port and I can connect the dock and use the HD using that. I tried different cables too, but nothing happens. Was there any recent change (last time it worked was, I think, in May or June) in the USB device driver that can prevent the connection? Some settings to change?

FC28: How do I get Vulkan working on intel laptop ?

One thing might be that it is saying the paper length > is 8.5x14 when I am scanning 8.5x11? But I can't find where to config this. I have an all-in-one HP3055. I use hplip to set up the printer side, scanimage to scan, and gscan2pdf to create pdfs from the tiff images. scanimage is part of the sane-backends package. hplip seesthe scanner at hpaio:/net/HP_LaserJet_3055?ip=192.168.99.112 I export that: export hpaio="hpaio:/net/HP_LaserJet_3055?ip=192.168.99.112" I use scanimage from the command line with a script. The main command line is: Script 'scanner' sets the export variable and calls: cd $1 scanimage --device-name=$hpaio --source auto --resolution 150 --format tiff --mode Color --contrast 125 -x 220 -y 290 --batch=$2%d.tiff --batch-start=$3 --batch-count=$4 --batch-increment=$5 $1 is the folder to dump the images in to; $2 is the starting part of the file name: some-page- $3 is the starting count number x: -> some-page-x $4 is the number of pages to scan y: -> some-page-(x+y) $5 is the batch increment: -2 lets you number the pages downwards: especially useful when you have a stack of double-sided pages to scan. The 'source auto' switch uses the adf: depends upon the 'page loaded' sensor to realize that the page feeder is in use. Paper length is set in mm by the x 220 y 290 parameters: legal length: y 355 The scanadf program is supposed to do this too, but I had no luck getting it working on a networked printer back about Fedora 16 and have not tried since. I found it much easier to set up a script to handle scanning, and just call it with the 5 parameters set out above. Once I have the scanned images, I use gscan2pdf to create the pdf files. gscan2pdf has scanning capabilities but also has problems with a networked scanner: it finds the scanner but cannot open it to scan. The same scanner script using scanimage works nicely with USB scanners such as a Brother 1000ADS, using 'export ads='brother4:bus1;dev2' and --device-name=$ads in the scanner script. I have literally scanned thousands of pages with this setup. Geoff

scanning from a network attached printer
by Robert Moskowitz 09 Oct '18

09 Oct '18

I have an HP8600 attached to my network. I can use its web interface to scan one page, but not its APF to scan multiple pages. The pdf generated cannot be opened by any software I have found.f A friend told me that he uses a twain driver on his Windows system to get to his network attached HP printer/scanner. Blast from the past; I have not touched twain for 15 years at least... So what is the equivalent way to do this from Fedora 28? thanks

WD NVMe - WDS500g2x - still no support
by lejeczek 09 Oct '18

hi there I wonder if any of you guys has WD's NVMe like this: https://www.scan.co.uk/products/1tb-wd-black-v2-m2-2280-pcie-30-x4-nvme-ssd… and like me, see no support for it in Fedora's kernels? I'm trying F29 but even there this model does get detected. thanks, L.

PHP-FPM, PHP code in browser
by Benjamin Smith 08 Oct '18

08 Oct '18

I'm unable to get PHP too actually *run* instead of just downloading the PHP sources. Coming from years of experience with Mod PHP wand I know that PHP FPM is different. I've confirmed that both RPMs (native FC 27) are installed, and that PHP-FPM and Apache are installed. I tried moving /etc/https/conf.modules/PHP.conf. I've looked at /etc/https/php.conf and read all comments. I've restarted phpfpm and Apache via system ctl. I've restarted the system. How do I get Apache to connect to Phpfpm for PHP scripts?

Are these instructions meant to be executed on Fedora Server 28?
by Turritopsis Dohrnii Teo En Ming 08 Oct '18

08 Oct '18

Good afternoon from Singapore, I came across this Linux Journal article titled "DIY: Build a Custom Minimal Linux Distribution from Source", written by Petros Koutoupis. Link: https://www.linuxjournal.com/content/diy-build-custom-minimal-linux-distrib… Are the instructions in this article meant to be executed with ease on Fedora Server 28 or perhaps easier on other Linux distros? Please advise. Thank you. ===BEGIN SIGNATURE=== Blogs: Turritopsis Dohrnii Teo En Ming's Academic Qualifications as at 30 Oct 2017 [1] https://tdtemcerts.wordpress.com/ <https://tdtemcerts.wordpress.com/>[2] http://tdtemcerts.blogspot.sg/ <http://tdtemcerts.blogspot.sg/>[3] https://www.scribd.com/user/270125049/Teo-En-Ming <https://www.scribd.com/user/270125049/Teo-En-Ming>===END SIGNATURE===

copy /home on one laptop to another
by Ranjan Maitra 07 Oct '18

07 Oct '18

Hi, I have a new laptop and have installed F28 on it. The old laptop is also running F28. I would like to copy /home from the old laptop to the second. What would be the best way to do this? Both are on the network, but I am hoping for a solution that does not go through the network. Any suggestions?

OT: fastest way to copy one drive to another
by Ranjan Maitra 06 Oct '18

06 Oct '18

Hi, I have two drives mounted on a F28 system. Both are identical 4TB drives. The second one is empty. I am concerned about the first one failing so would like to copy the contents (which are around 3.7 TB) to the second. What is the fastest way to copy the contents of the first drive to the second? I was using rsync, but is there a better way? Many thanks in advance for any advice, Ranjan -- Important Notice: This mailbox is ignored: e-mails are set to be deleted on receipt.
