NFS acting weird?
by Tom Horsley
I've got filesystems hosted on centos 7. They are mounted
(nfs4) on my newly configured fedora 29 desktop.
I'm debugging an executable that lives on the NFS filesystem.
I make changes and recompile over on the centos system.
I try testing the newly compiled executable on fedora 29
and it acts totally strange in ways that make no sense.
I reboot the fedora 29 system and try testing again, and
everything seems to be as expected.
I can't put my finger on anything specific, but it sure seems
like NFS is at fault somehow.
When I had fedora 28 on this same desktop and was doing the
same kind of development, the strangeness never manifested.

F28 help with firfox-tls-proxy
by Robert Moskowitz
greetings
i am in a hospital bed pecking left handed from being hit by a car,
instead of in bankok for ietf meeting.
this hospital's firewall/proxy is giving firefox problems connecting to
ietf.org
Secure Connection Failed
The connection to the server was reset while the page was loading.
The page you are trying to view cannot be shown because the
authenticity of the received data could not be verified.
Please contact the website owners to inform them of this problem.
I am hoping that someone can help me disable FF checking. IT at the
hospital is hard to reach...
thanks

(F28) Lost touchpad scrolling Synaptics
by tonynelson＠georgeanelson.com
Touchpad edge scrolling had been working with libinput. I installed
xorg-x11-drv-synaptics-legacy-1.9.0-7.fc28.x86_64 to get back having
typing disable the touchpad momentarily (y'all know why). For a little
while, touchpad scrolling worked properly, and then it got erratic
so that I thought it was a kernel update, and then it stopped working
at all. Removing synaptics and rebooting and thus returning to
libinput has brought back touchpad scrolling. It also seems to have
retained that little touchpad insensitivity while typing. Can anyone
explain or tell me how to figure this out?

devel changes :: recommendation for changes
by Adrian Sevcenco
Hi! Starting with f28 there were some changes in glibc components (and i
think not only that) .. so, regarding tirpc contents now should be
enough to add -I/usr/include/tirpc ?
what is the difference between tirpc and ntirpc ?
can ntirpc replace tirpc ?
also i have some autoconf problems : link step that used to work in f27
now does not find references ...
Does anyone have any ideas/advices related to these?
Thanks a lot!!

Why this activity on mounted but unused fs?
by Eyal Lebedinsky
While configuring a new raid I ran iostat to see that it is idle. It was, and there
was no io showing at all.
I then mounted it on a new mount point which I have no process using. I started hearing
knocks from the PC case, and touching the disks revealed that they all had activity 1-2
times a second, concurrently, leading to the louder than usual noise.
Here is what "iostat 60" is now showing on a totally idle system (this is a very typical entry):
avg-cpu: %user %nice %system %iowait %steal %idle
0.21 0.00 0.19 1.36 0.00 98.24
Device tps kB_read/s kB_wrtn/s kB_read kB_wrtn
sda 0.73 0.93 4.07 56 244
sdb 5.87 8.53 20.78 512 1247
sdd 6.67 10.93 23.18 656 1391
sdf 8.50 40.27 52.52 2416 3151
sde 6.20 4.40 16.65 264 999
sdh 5.97 10.13 22.38 608 1343
sdg 7.77 38.00 50.25 2280 3015
sdc 5.87 8.53 20.78 512 1247
md127 1.80 0.00 40.27 0 2416
sda is the root fs (ext4).
md127 (ext4) is a RAID6 of 7 disks sd[b-h]1.
What is this io, and can it be stopped? I want to allow the disks to enter
low power mode (not spin down) when idle.
This is up-to-date recent install of f28 (this is a test system, so not customized).
TIA

interrupted upgrade F28 -> F29 hosed dnf
by Greg Woods
I was upgrading a system from F28 ro F29 and the power failed during the
upgrade. I don't know what point the upgrade was at when it failed. The
basic problem is that most (but not all) dnf commands just die with a
traceback:

RuntimeError: Exec failed: no such table: main.trans_cmdline
[root@elric greg]#
When I first brought it back up, there were a lot of dups (f28 and f29
packages both installed). I painstakingly (using rpm) removed all the dups,
so that now "dnf check" runs with no output (other than the locale
complaint). But commands like "update", "check-update", "install" will just
get the traceback. The system seems to be running OK (although still with
an F28 kernel), but of course it is now impossible to update it.
Is there a way to fix this? I'm thinking I could have had a working system
by now by just installing F29 from scratch, but I'm also trying to learn
here. Is a full install my only option at this point?
Thanks,

OT: how to get shell status of first pipe shell command (when
fail), not that of the last one
by Dario Lesca
When I concatenate 2 or more shell command with pipe (|), I get only
the status of last one.
For example: "some-cmd | logger -t "some-cmd messages:"; echo $?"
If "some-cmd" fail with status !=0 I get always status of last one, in
this case 0
In my case if the first command fail, I must send a warning message
A more simple example is: "false | true"
I want get status 1, of first command (false), not 0 (true)
I have also try "sh -e -c 'false || exit 2|true'; echo $?" but I get
always 0
How to I get first status and break the chains of pipes ?
Many thanks

issues with F27
by Paolo Galtieri
I have F27 running on a couple of systems. On one of them I have
encountered the following 2 issues.
1) System crashes with "System not configured for semaphores". This
error results in the system halting. It has occurred several times over
the last few months.
2) I have a Linksys AE1200 wireless adapter. Every time I reboot my
system this device does not come up. I have to unplug it and plug it
back in before the system sees it and configures it.
Both issues have occurred on different kernels over the last few
months. I also happen to have a Linksys AE1000 plugged into the same
system and it comes up every time.
I updated to the AE1000 because I started experiencing problems where my
internet connection would go away even though I was still connected to
the cable modem via wireless. I thought I was having problems with the
wireless adapter so I bought a new one. This has not solved the problem
completely, but it has reduced the problem considerably.
Any ideas on what might be causing these issues?
Any help is appreciated.
Paolo
