anaconda problem with local repo

2018-09-03 Thread 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.

Thanks very much. I found some Fedora=specific information here wrt the MS SP3. 
https://www.reddit.com/r/SurfaceLinux/comments/4pfamk/fedora_24_works_very_well_on_surface_pro_3/

However, it is not clear to me if KDE or LXQt has this feature of opening up of 
the on-screen keyboard so maybe Gnome is where I am headed.

Re: scp over wireless is slow

2018-09-03 Thread Cameron Simpson

On 03Sep2018 13:07, Jakub Jelen  wrote:

SCP protocol is really slow, especially on networks with high latency
(wireless). The reason why is mostly the size of buffers, which is very
small and SCP waits for every part to be confirmed by the remote host
before sending another part.


This is categorically false. I've just read through the code to confirm.

The only round trip stuff in scp is at the start and end of the file transfer, 
when it sends the starting file permissions and checks receipt, and at the very 
end. During the transfer it just chucks data at the TCP connection as fast as 
it will accept it. Its internal buffer isn't particularly large, but that is 
irrelevant because (a) the OS reads from files in a sensible fashion and (b) 
TCP colesces writes into the same packet if they arrive fast enough and there's 
room.


So if you're transferring a lot of quite small files, the start/end file 
transaction can get in the way.  But large files go through pretty much at the 
network speed (or the disc speed if the discs are slow and the network is 
fast).


In years of using scp, it has always been pretty fast. And rsync notably slower 
for complete-file copies.


I think Jakub has been misreading the code, probably the atomicio() function, 
which _doesn't_ do an end-to-end delivery of the current buffer; it is just a 
wrapper around the OS read/write call, which may return a short result if its 
underlying buffer empties/fills. That is a _local_ buffer, such as the TCP send 
buffer.


Also, calling a home LAN wireless connection high latency is a bit special 
purpose. It may be higher latency than your wired ethernet, but it is still 
pretty low.


By comparison, I just copied a decent sized file, using scp, over a satellite 
link. Round trip packet time of 600ms-700ms best case. Throughput was 
consistent with my ISP speeds: 5Mbps up, 25Mbps down.


The network packet latency is _not_ a particular issue with scp, because it 
doesn't do the per-buffer end-to-end checks Jakub imagines.



You can google "scp speed" and you will get a lot of answers, sometimes
wrongly accusing the encryption or the compression, but really, the RTT
and buffers are the fault as I write here:

https://superuser.com/a/1101203/466930


I read that. It's a about a paragraph of text with no discussion.


SCP should be really used only as fast hack for copying files in fast
local networks. For all other cases, use SFTP or rsync if you need
something more complex.


Really, no. Use whatever works best. Scp is fine for large files. For 
incremental change, use rsync (which does a lot of checksum passing to skip 
identical data areas) and for lots of small files use tar or cpio piped over 
ssh, which removes another layer of round trip latency (the per-file sync).


Cheers,
Cameron Simpson

I don't have specific numbers, but I just copied a couple of
linux distro iso files (about 700-800 MB each) to a windows
box I have that uses AC class wireless. Seemed almost as
fast as wired to me. (This was using a windows share hosted

Maybe I'm just patient, but I didn't get the impression

I also get the same results with sftp.

sftp chris@f28s.local

sftp> put test.bin

~9MBit/s server to workstation, per nload
~4.9MBit/s workstation to server, per nload

Whether I push or pull the same file with samba, it's 39-44Mbit/s.

I'm using a Fedora install ISO as the test file so it's not really
compressible since most of the payload is already xz compressed.

Going from server to workstation, I get double the rate according to
nload. 9.1Mbit/s server to workstation, and 4.9Mbit workstation to
server.

Same results with:
rsync test.bin chris@f28h.local:~/Downloads

Does that automatically do it over ssh and end up with the same problems?

Separate issue, but related, dd-wrt reports

The Fedora Workstation Tx and Rx rate is usually 270M but during idle
it's often 6M. This is a:
6c:00.0 Network controller [0280]: Intel Corporation Wireless 8260
[8086:24f3] (rev 3a)

The Fedora Server Tx and Rx rate is never greater than 135M even
though it's closer to the AP. This is a:
02:00.0 Network controller [0280]: Intel Corporation Wireless 3165
[8086:3165] (rev 81)


So for some reason, the server (an Intel NUC) never uses a rate higher
than 135M.

Anyway, in the case where the server is wired, the only 5Ghz wireless
device is the workstation, so no relay. But if the server is wireless,
then both server and workstation are competing and relay is happening.

It might be this old WRT600N is starting to crap out, even though it's
recently reflashed with a current version of dd-wrte. On 2.5Ghz, my
Android phone freaks out every 2-3 days, kernel wake locks prevent the
CPU from idling, and it soaks the battery at a 10%+ rate per hour
doing nothing. Reboot the router? Problem solved for 2 more days. So
does disassociating from that AP. Or airplane mode. Reassociating
without rebooting the router instantly triggers the kernel wake locks.
One of the weirder phone batter problems I've seen.

GUI setup for quasi real time process ?

2018-09-03 Thread 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.

I've been hoping to find a solution for this as well as I'm planning on
upgrading my computer to a Ryzen 5 later this year. I think what I'm going
to do since I'm upgrading to a M.2 SSD at the same time is:

1. Just do a plain install of Fedora to the new disk and then reboot in a
live system (Fedora or maybe System Rescue CD since it'll have all the
utilities I need)
2. Delete the default LVM VG it created
3. Move my "/" and "/var" volume groups over from the old SSD.
4. Tie in my /home drive which is still a 2TB spinning disk.
5. After that I should just have to check / update /etc/fstab.

SCP protocol is really slow, especially on networks with high latency
(wireless). The reason why is mostly the size of buffers, which is very
small and SCP waits for every part to be confirmed by the remote host
before sending another part.

You can google "scp speed" and you will get a lot of answers, sometimes
wrongly accusing the encryption or the compression, but really, the RTT
and buffers are the fault as I write here:

SCP should be really used only as fast hack for copying files in fast
local networks. For all other cases, use SFTP or rsync if you need
something more complex.

AFAIK the only use most people have for AV software on Linux is when
they're running a mail server and want to filter certain kinds of spam
from reaching their Windows users. I do online banking in Fedora and
have never installed AV software. My bank also has a general warning
about using AV (which they seem to use as a catch-all term for any kind
of anti-malware). I just ignore it.

[BTW, anyone else see the irony that most banking websites will not let
you use a password manager?].

which antivirus sw for Fedora?

2018-09-03 Thread Joerg Lechner via users

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
