scp over wireless is slow
by Chris Murphy
Fedora 28 Server
Fedora 28 Workstation
dd-wrt 802.11n Broadcom based router
Connected wirelessly 5GHz, wired ethernet cable is physically
disconnected from Server
File transfer from Workstation to Server
scp: scp itself reports ~620KB/s; where nload on the server reports ~4.9Mbit/s
smb: GNOME reports 4.9MB/s; where nload on the server reports ~39.8Mbit/s
Why? That's rather unexpected.
Command is
scp test.bin f28s.local:/srv/scratch
Using nc, I get speeds slightly faster than smb. OK so encryption? If
I connect wired, and then 'nmcli c down <ID>' to disconnect the
wireless connection:
scp: 12MB/s, nload ~101Mbit/s
smb: nload ~96Mbit/s
Sooooo, it's not encryption. Why would scp be this much slower only
with a wireless connection? And using:
rync -avzhe ssh test.bin f28s.local:/srv/scratch
Over wireless, this is just as bad as scp.

Tip: finally found a USB 3.1 card that works with 28
by ToddAndMargo
Hi All,
I finally found a PCIe USB 3.1 adapter that works perfectly
with Fedora 28:
Syba SD-PEX20200
https://www.amazon.com/gp/product/B019LHXZOA
Tested and failed were:
StarTech.com PEXUSB312C Dual Port USB 3.1 Card – 1x USB-C – 1x
USB-A Large file transfers crash your operating system
Siig JU-P20A12-S1 2-Port USB 3.1 PCI-Express Host Adapter
Card Type-A/C 1 st attempt: A port worked, c port only provided
power. 2nd attempt (send back for repair): both ports
only supplied power. Tossed in the trash.
Ableconn PU31-1A1C USB 3.1 Gen 2 Type-C & Type-A PCIe x4
Host Adapter Card both ports: Aug 23 19:24:47 localhost
kernel: usb 6-1: new SuperSpeed USB device number 5 using
xhci_hcd Aug 23 19:24:47 localhost kernel: usb 6-1:
device descriptor read/8, error -61
I though I'd never find one!

preferred desktop environment for MS Surface Pro 3
by Ranjan Maitra
Hi,
I would like to install Fedora on my MS Surface Pro 3. I do not have much experience with tablets so I was wondering which DE or spin I should put on it. I guess I would like the keyboard to change when the Surface changes from PC mode to tablet mode and vice-versa if possible. I would also be able to write on it and create documents in pdf, etc for notes.
Am I better off using KDE or LXQt or Gnome? If the latter, is it worthwhile to install the Design Suite spin. I must say that I am not very keen on bloated software but I am open to it. I myself run a non-DE (openbox) environment on my computers and have never gone beyond trying a DE and giving up on it because it is noticeably a bit more sluggish. However, I do recognize that a tablet mode is different and perhaps better handled with a DE. So, I am open to all suggestions and also practical tips.
Many thanks in advance and best wishes,
Ranjan

RE: automatically mount all luks partitions at startup, not only
/home
by J.Witvliet＠mindef.nl
How about specifying the luks-pwd for all other partitions/VolumeGroups by means of a LUKS_passwordfile?

You can maybe put a line in fstab for the partitions you want to mount at startup and you will be prompted for the passphrase if a partition is encrypted.

Firewall Configuration Details
by Stephen Morris
Hi,
Is there any step-by-step documentation anywhere on setting up a
linux firewall from scratch that is designed for someone who has never
even looked at what is required for this before?
Is there any recommended gui packages that simplify the setting
up/ongoing configuration of the firewall?
Is there a gui interface to the firewall that will monitor
outgoing/incoming transactions and prompt for whether or not they should
be allowed or denied?
The reason for these questions is I replaced my Linksys wireless
router with a Dlink wireless router over the weekend (with the issues I
had I also replace my Dlink DWA-192 adapter with a Netgear A7000, but
like the DWA device the Netgear device is not supported under Linux so I
going to have to search for drivers for that now too) and under Windows
10, all applications and games (standalone games, games run from their
own launcher and games run under steam) were prevented from Accessing
the internet, but a browser like Chrome was able to still access the
internet. Under Fedora I had no issues at all and games run through
steam ran quite happily, albeit without sound.
After a lot of playing around with changing wireless adapters and
changing router configuration, to do things like turn off the router's
firewall, opening ports in the router used by the games I play, setting
up port forwarding, putting my pc outside of the router's firewall by
putting it in the DMZ, all to no avail, I eventually found through trial
and error that the issue was a setting I had active in the third party
firewall I use in Windows, which was to activate 'ARP Spoofing
Checking'. The only way I could access the internet was to turn this
option off.
With windows have this issue caused by the firewall but linux not
having the issue presumably means that either the windows firewall is
more restrictive than Linux, or, I don't have the linux firewall
configured properly, hence the questions above.
The firewall I use under windows, and the native windows firewall,
both have the ability to prompt for allowing or disallowing access
requests not covered by explicit rules, and provide the ability to
generate permanent rules depending on the answer, hence the question
above of whether the same functionality exists under Linux?
Thanks in advance for any help provided.
regards,
Steve

Kickstart
by Louis Garcia
I've been playing around with kickstart to install workstations and need
this to start graphically:
# Start graphical environment on boot
xconfig --startxonboot
Is this correct in the wayland world? Last few releases defaults to wayland
instead of X. Will I get gdm on wayland?
Thanks

GUI setup for quasi real time process ?
by linux guy
We need a gui for a quasi real time process, which will run on a dedicated
computer. We need to be able to view and control the process from a
number of terminals, some on the local network, some remotely, over the
Internet. I hope all the terminals will run Linux, but invariably someone
will want to run Windows.
What is the best way to set something like this up ? Use a web server to
interface with the process and web browsers to view and control it ?
Write a Java app to interface directly with the process ?
All thoughts, ideas and advice is welcome.

anaconda problem with local repo
by Louis Garcia
Having many boxes to setup I decided to setup a local repo of fedora. I
setup vsftpd for this repo. I won't go into every step unless someone asks.
Either through pxe or netinst boot I'm able to boot into anacanda and setup
everything except the software packages. Everything in the software spoke
is empty. Then I point anaconda to another mirror and software spoke is
fine.
How I populate my copy:
#rsync -av rsync://
mirror.utexas.edu/fedora/linux/releases/28/Everything/x86_64/os/
/srv/repos/fedora/28/x86_64/os
I think I'm missing something in my repo.
Thanks.

which antivirus sw for Fedora?
by Joerg Lechner
Hi,
doing onlinebanking in my bank contract I read, I have to use antivirus sw, otherwise I would be responsible for probably misuse. So far I made onlinebanking, when I am logged in in Fedora without antivirus sw. But to be correct, as the bank says, I would like to use antivirus sw. For me it's no problem to have i.e a F28 installation with antivirus sw separatly for "critical" use of F28. I have F28 on an usb flash medium, and 32GB flash media are not too expensive, so fo all other usages of Fedora I don't need antivirus sw and can use another Fedora installation. Which antivirus sw should I prefer?
Kind regards
