Re: dnf gets stuck on poor connections

[Sylvia Sánchez]

Mmmhh... My connection isn't very reliable either but dnf doesn't get stuck.
Maybe you should update packages in small bunches instead of
everything altogether.

Just an idea, hope it helps you.

However it continues to want to update a few with the rc1 rpm's which 
seems inadvisable ...


What am I missing?

This installation began as Fedora-23 beta and seems to work perfectly 
otherwise. As I said I first noticed this yesterday.

I also start with:

rpm -q --qf "%{NAME}.%{ARCH}\n" -a | sort > rpms.txt

I run it on both old and new to get a lits of rpms
without any specific version numbers. I can then
compare them with the "comm" tool to get lists of
rpms on one system but not on the other.

That doesn't help with all the rpms that have been dropped

Scale grub resolution on a HiDef screen (Fedora 23)?

[CS DBA]

Hi All;

I just received a new laptop, the Lenovo X1 Carbon with the 2560x1440 
IPS screen.

I installed the Fedora 23 KDE spin, changed the screen resolution in :
System Settings --> Display and Monitor

Then I was able to change the login screen resolution by adding an 
/etc/X11/xorg.conf file with this content:

Section "Screen"
Identifier "Default Screen"
SubSection "Display"
Modes "1280x720"
EndSubSection
EndSection


The login screen and the screen once I'm logged in now look wonderful 
(and readable)


The last bit is the grub menu / grub boot screen.  The text is 
practically microscopic.
If I ever need to boot into single user mode and need to actually read 
the text it's

going to be a problem.

I found this solution :
https://ask.fedoraproject.org/en/question/23526/how-can-i-change-boot-menu-screen-resolution-in-grub2/

But it does not seem to work,  I changed my /etc/default/grub file to 
look like this:

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora_f23host/root 
rd.lvm.lv=fedora_f23host/swap rhgb quiet"

GRUB_DISABLE_RECOVERY="true"
GRUB_GFXMODE='1368x768x32; 1368x768x24; 1280x720x32; 1280x720x24; 
800x600x32; 800x600x24; auto'

GRUB_GFXPAYLOAD=keep

with no luck...

Can someone point me to instructions how to change my grub screen 
resolution? and ensure that resolution stays in place if I ever need to 
go into single user mode?


Thanks in advance

Try it again with more than 10 lines in the input. That asort()

will be 1, 10, 100, 101, 102, ... 109, 11, 110, 111, 112, ... 119,

Ran this after the above:

still  no luck,


found a post about efi systems, so I ended up doing this:

1)  grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

2) ln -sf /boot/efi/EFI/fedora/grub.cfg /etc/grub2-efi.cfg

still no change in my boot menu resolution...

thoughts?

Dear All,

Thanks in advance,


You might need to explain the reason for your request since, it may
change the answer.

As an example, my computer has a GigE port that runs to a 100Mbit
simple switch before getting to anything else.  So I would be limited
to a theoretical maximum of 100Mbit but I might want to know how fast I
can transfer files to/from another computer in my LAN.  The bottleneck
here could be the switch, my NIC, the other computers NIC, OS limits,
firewall slowdowns etc.

So, for me I would really want to test an actual file transfer using a
number of setups.  Depending on each computer I could try Samba, FTP,
SCP.  I might run a wire to bypass the switch.  I might try with
firewalls and antivirus disabled.

All this will also give me some clue on how fast I could run if I was
able to get a fiber connection, to let me know if my system would be a
serious limit to getting the full 1G of true fiber.  Obviously the
switch would have to be upgraded in my case.


Generally speaking, any given NIC that has proper firmware and is in
a relatively modern computer will run very close to the rated wire
speed--provided the other end of the cable can handle it as well. Note
that the effective transfer rate will usually be about 80-95% of that
(for a 1Gbps NIC, 800-950Mbps).

This does not include any overhead involved in the protocol used. You
will find that things like FTP, rsync and the like will show lower
data transmission rates (e.g. multiplying the number of bytes
transferred by 8 to get number of bits transferred) due to their
overhead and that they're dealing with TCP's inherent nagle algorithm
and handshaking. TCP is designed to make sure things get to where
they're supposed to go, and with that comes a lot of overhead. Things
like UDR (rsync-over-UDP) will show much closer to the theoretical data
transmission rate due to its use of UDP.

The most common bottleneck to raw speed is the wire, switch, router,
gateway or ISP that the NIC is connected to. You'll rarely find the NIC
itself the limiting factor.

No missing quotes. It's an awk program, not a bash one, $0 is a bash
variable. The only syntax errors I see are no brackets around the for
statement and missing closing brace. My awk here is too old to support
PROCINFO["sorted_in"], so here's a slight tweak using asort:

awktest:

{
lines[NR]=$NF " " $0
}

END {
#PROCINFO["sorted_in"]="@val_type_asc"
asort(lines, ordered)
for (ind = 1 ; ind<=length(ordered) ; ind++) {
   line=ordered[ind]
   j=index(line, " ")
   print substr(line, j+1)
}
}


awktestinput:

$ awk -f awktest  < awktestinput

Re: eclipse stop after f22->f23

[Łukasz Posadowski]

13.11.2015 o 18:19, jd1008:

So far I have seen so many complaints and problems with fc23,
I am beginning to doubt the veracity of the flowery reports about
upgrading to fc23.

It's the same story every time. :) Fedora isn't know for caring much about 
compatibility with 3rd party software.

Maurizio: backup ~/.eclipse and workspace directories and try just plain 
Eclipse from 
http://download.eclipse.org/eclipse/downloads/drops4/R-4.5.1-201509040015/ . 
Download a Platform Runtime Binary. This would get all extension out of the 
way. If it will work, you could install your extensions one by one.

Apparently my brain and my typing move at different speeds, "$0" here
is an *awk* variable, as poc also points out.

Thanks in advance,



You might need to explain the reason for your request since, it may
change the answer.

As an example, my computer has a GigE port that runs to a 100Mbit
simple switch before getting to anything else.  So I would be limited
to a theoretical maximum of 100Mbit but I might want to know how fast I
can transfer files to/from another computer in my LAN.  The bottleneck
here could be the switch, my NIC, the other computers NIC, OS limits,
firewall slowdowns etc.

So, for me I would really want to test an actual file transfer using a
number of setups.  Depending on each computer I could try Samba, FTP,
SCP.  I might run a wire to bypass the switch.  I might try with
firewalls and antivirus disabled.

All this will also give me some clue on how fast I could run if I was
able to get a fiber connection, to let me know if my system would be a
serious limit to getting the full 1G of true fiber.  Obviously the
switch would have to be upgraded in my case.



Generally speaking, any given NIC that has proper firmware and is in
a relatively modern computer will run very close to the rated wire
speed--provided the other end of the cable can handle it as well. Note
that the effective transfer rate will usually be about 80-95% of that
(for a 1Gbps NIC, 800-950Mbps).

This does not include any overhead involved in the protocol used. You
will find that things like FTP, rsync and the like will show lower
data transmission rates (e.g. multiplying the number of bytes
transferred by 8 to get number of bits transferred) due to their
overhead and that they're dealing with TCP's inherent nagle algorithm
and handshaking. TCP is designed to make sure things get to where
they're supposed to go, and with that comes a lot of overhead. Things
like UDR (rsync-over-UDP) will show much closer to the theoretical data
transmission rate due to its use of UDP.

The most common bottleneck to raw speed is the wire, switch, router,
gateway or ISP that the NIC is connected to. You'll rarely find the NIC
itself the limiting factor.


Thanks to all respondents! I could now determine that my network card
is a 100Mbps Fast Ethernet, and now it is clear why the speed test
(http://www.speedtest.net/) shows a download speed of just 85 Mbps
when my contracted speed is 120 Mbps.


85Mbps sounds about right for a 100baseT NIC on one of those tests
(they typically use TCP). You can always verify your type of NIC using
ethtool.

My laptop has a 100baseT port. When I need gigabit, I use a USB3 gigabit
dongle. Note that you need USB3 for this--USB1.1 and USB2 aren't fast
enough.

Thanks, Rick. The idea of using a USB3 gigabit dongle is great --
better than replacing the network card!

RTFM, awk(1) in this case. $0 refers to the whole input record (i.e.
the current line), which is why fields are numbered from 1.

I haven't looked at the rest of the script.

As current Audacity packager, I'm keen to find out more about your issue.

What name, version release was first version with all the errors ?
Did you happen to screen shot, or capture text console output ?

Also, the same for the update you received. I expect that
audacity-freeworld should not replace audacity. Is that what happened
with dnf update, or was that a manual process. If you start from a
terminal prompt, what text is output ?

By the way, I also need testers for the future Audacity 2.1.2 (alpha)
which I've built [1] and should be in -testing soon. Unfortunately, no
RPMFusion -freeworld builds for 2.1.2 alpha yet.

Dave.

I have faced this problem too, my internet connection is 512kbps, but
before dnf in the memorables yum days I never had this kind of
problems.

Did you added this lines to the dnf.conf configuration file?

keepcache=true # This config line adds the capability of keeping the
cache and the dowloaded packages on the cache if something got stuck
and you need to restart it without having to download the already
downloaded packages again.

deltarpm=true # This config line will retrieve delta rpm's packages
for download updates instead of downloading the full packages, it save
time and data if you are using 3G or LTE connections.

fastestmirror=true # This will force dnf to keep a cache of the most
efficience mirrors.

To add it:
su -c "echo 'keepcache=true' >> /etc/dnf/dnf.conf"
su -c "echo 'deltarpm=true' >> /etc/dnf/dnf.conf"
su -c "echo 'fastestmirror=true' >> /etc/dnf/dnf.conf"

I must confess that even adding this to my dnf.conf file sometimes the
problem back or appear.

Also there is a bug about dnf-make cache service, it tries to run on
the boot up, get stuck and if the user try to run a dnf update cause
this annoying problem.

https://bugzilla.redhat.com/show_bug.cgi?id=1187111

You may try this:
1. Kill the dnf-makecache process

2. Clean all the dnf cache:
su -c "dnf clean all"

3. And then make the cache:
su -c "dnf makecache"

If you are under a slow internet connection make sure that there is
not any other process that might drain your bandwidth.

It's probably a lock left over from the failed start.  That is, the new
version of audacity thinks audacity is already running because the
failed version left a lock set when it exited.

Look in your home directory for a dot file, probably something
like .audacity, or a .lock file in an audacity folder.  Remove it, and
audacity should start if there are no errors.

WIFI dongle stopped working

[Gary Stainburn]

I have a HP Envy running F21.  THe built in WIFI would not work so I bought a 
dongle from The Pi Hut

http://thepihut.com/collections/raspberry-pi-wifi/products/usb-wifi-adapter-for-the-raspberry-pi

This worked straight out of the box.

However, recently I realised it wasn't working, but don't know when it 
stopped. I can't think of anything that could have happened other than 
routine yum updates.

The following is what appears in /var/log/messages if I boot up and then plug 
in the dongle.

I'm very much a non-techy when it comes to linux internals, but it looks to me 
like Linux no longer recognises the device.  Can anyone give a clue why, or 
what I need to do to fix it?

dnf gets stuck on poor connections

[Suvayu Ali]

Hi,

Lately I have been on unreliable connections.  I noticed that after I
have my laptop running for a few days, dnf stops working.  Any dnf
command hangs indefinitely.  I can get back to the shell again by
killing the process with SIGKILL.  It seems to me this happens when the
dnf-makecache service gets stuck.  I have tried restarting it, but it
does not help.  Restarting the dnf-makecache timer does not help either.
Of course all this goes away after a reboot.  But then that's not really
a solution.

Any ideas anyone?

TIA,

It's not just commands where access to the repo is needed.  Even
commands like search hangs.  I think the makecache service is locking
the database and hanging.  Since it hangs, my interactive command waits
for the lock to be released indefinitely.  I can't prove this though,
this is my hunch based on the symptoms I see.

Okay good, I'm not alone then.

Simple search or clean commands should not hang if this was the reason.

Thanks for the responses so far, any other thoughts?

Cheers,

Script/list of everything installed on old F20 box (yum) to new F23 box (dnf)

[Ted Roche]

Hi, folks:

My old development workstation,

$ uname -a
Linux stupidname.mydomain.com 3.19.8-100.fc20.x86_64 #1 SMP Tue May 12
17:08:50 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

is finally getting replaced with a new machine,

$uname -a

Linux newstupidname.mydomain.com 4.2.5-300.fc23.x86_x64 #1 SMP Tue Oct
27 4:29:56 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Is there an easy way to query the database of installed stuff on the
old machine and turn it into a script to run on the new one? I know
there's the old config file, font, and script I installed by hand, but
this would get me a long way toward a working workstation.

I'm sure I can hack something together with

yum list installed

and flub my way through cut, sed, slice but if someone already has a
more elegant solution, I'd appreciate suggestions.

Audacity

[jarmo]

With new upgrade to F23 Audacity didn't start at all, got tons of
errors. This morning update, got new Audacity-Freeworld. Something new,
no errors, but Audacity won't start. Anyone else met this?

If it's make cache, you can try using Bleachbit to make a deep
cleaning. Maybe that works. It worked for me with yum.

Re: How can Fedora determine the maximum speed of network computer cards?

[James Hogarth]

For internet use your likely bottleneck is your wan connection anyway... In
which case the usual places like speedtest.net apply for determining your
up and down throughout.

If you want to carry out throughout tests of systems you own then it's
worth looking at iperf

Your Ethernet card will operate allways at its maximum speed (100Mbps if
Fast Ethernet or 1000 Mbps if Gigabit Ethernet with Cat5e or Cat6 cable),
until it reaches your Moderm/Router that connects you to your ISP, there is
the bottleneck, from your Modem/Router to "the cloud".

ethtool will list your network card's capabilities.

You might need to explain the reason for your request since, it may
change the answer.

As an example, my computer has a GigE port that runs to a 100Mbit
simple switch before getting to anything else.  So I would be limited
to a theoretical maximum of 100Mbit but I might want to know how fast I
can transfer files to/from another computer in my LAN.  The bottleneck
here could be the switch, my NIC, the other computers NIC, OS limits,
firewall slowdowns etc.

So, for me I would really want to test an actual file transfer using a
number of setups.  Depending on each computer I could try Samba, FTP,
SCP.  I might run a wire to bypass the switch.  I might try with
firewalls and antivirus disabled.

All this will also give me some clue on how fast I could run if I was
able to get a fiber connection, to let me know if my system would be a
serious limit to getting the full 1G of true fiber.  Obviously the
switch would have to be upgraded in my case.

Maybe you should update packages in small bunches instead of
everything altogether.


I am not on a poor connection, either, but I am occasionally 
experiencing this problem as well.


In most cases the cause seems to be dnf's mirror selection to prefer 
broken repos and/or poorly accessible mirrors, but I have also seen 
cases, when dnf hung without any feedback for hours.


My recommendation: Try yum, dnf is not ready for production use.

Isn't there a plug in for dnf to try repositories and then pull the
stuff from the fastest?
About yum, I don't think it exists anymore...

Dear All,

Is there something in Fedora that I might use to determine the maximum
speed the network card of my computer can attain on Internet? I am
thinking about wired Internet and not about wireless Internet.

You're thinking of the fastestmirror plugin ...

Note though that this only looks at ping times iirc which won't always
reflect overall likely throughout.
