LUKS question
by Wells, Roger K.
I have existing systems with un-encrypted disks.
I have tried unsuccessfully to encrypt them using LUKS.
Has anyone out there been able to encrypt an existing system (after the
fact, so to speak)?
TIA

Evolution's "To Do" pane
by Jonathan Ryshpan
I have just upgraded my system to Fedora-27, which has caused Evolution
to upgrade to 3.26.3 (3.26.3-1.fc27). Evolution now has a "To Do"
pane, which I don't want, since I use another program for calendar and
scheduling.
How can I remove the "To Do" pane?
Thanks - jon

Tweaking Fedora
by Beartooth
Within the next three weeks or so, barring any great surprises, I
hope to be putting Fedora 27 onto four PCs, a laptop, and a netbook. IIRC,
the netbook, which I haven't used recently, has F24 now; all the others
are running 26. I'll do all I can by upgrading, because every time I do a
fresh install, it costs me something more than a whole day per machine to
do the tweaking I need.
(I've been running Fedora since it was RedHat7; so my trifocal
fingers and arthritic eyeballs know their jobs IF I get all the tweaks
right -- a great boon and a bringer of cyber-survival, since I also keep
getting slower and more forgetful....)
A correspondent on another list says one used to be able to use
Mondo Rescue to grab all the settings on an existing install and clone
them onto a new one. That would save me vast tedium.
But the Mondo Rescue site lists only rpms for Fedora 23 and
before. And either I'm garbling my correspondent's directions, or they
don't work any more -- or both.
I tried a few variations on "dnf install Mondo-xyzq". I also
downloaded a few .rpms from Mondo's repository and ran "rpm -ivh" against
them. Both tries failed.
Is there a tutorial somewhere? Has Mondo Rescue forked into
something with another name? Have the Fedora Gurux and Alpha Plus
Technoids come up with a replacement while I wasn't looking??

Resolve fc27.i686 vs. fc27.x86_64??
by Beartooth
Probably in connection with some version of yumex, I have somehow
gotten both */fc26.i686 and */fc26.x86_64 forms of a dozen or so rpms for
compiz.
This has not been a problem till now. fc26 (and, unless I'm
misremembering, fc25 and fc24 before that) has just ignored the
superfluous ones. But now system-upgrade is choking on the ones for fc27.
The machine is actually .x86_64, as I have now discovered. I
tried adding --allowerasing and --allowerasing --best, but with no
success.
Do I dare do something like "dnf remove compiz"?? (Or perhaps
"dnf remove */compiz/*/.i686 ???)

The 'Y' server is in the eth0 subnet.
'Y' has to be resolved by the DNS.
As said before, even pinging the gateway IP succeeds only more than
20s after the routes (as seen by "ip route") are defined.
Weird no?
Cisco switch and that delay for traffic on a static address?
Sounds like symptoms of STP delaying s port from listening to forwarding...
Have you looked at disabling on that interface or setting portfast if it's
only host facing?

Samba support fails in F27
by Temlakos
Everyone:
After several days of fruitless effort I have to bring this to the
community. Since I upgraded to F27, I have never been able to sustain
any viable network connection to other computers on my network that run
Windows 10. Which means if I ever have to transfer files between or
among them, I have to use USB flash drives or even USB-connectable
moveable HDD's.
Now I suppose I could buy a spare Western Digital Passport for this
application. But I would like to know what I'm missing.
For the record:
The computer I'm typing this on, that runs F27, presently has a wireless
connection to the network. I hope, within the next two months, to move
to an environment where I can connect this computer to the network using
a MoCA adapter, a switch in the room, and a coaxial connector in the
wall to connect this computer, a printer, and maybe a laptop if I bring
it into the same room. That never used to make any difference, but yes,
I'm going to try to "remedy" that "fault" (if anyone here chooses to
find fault with using a wireless connection).
The Samba workgroup is named Home. That's case-sensitive.
I have User authentication on the Samba server.
I created Samba user accounts for every Fedora user account on this
machine--all three of them.
With F26, I could always look up Home under Samba Shares and find it.
But now--nothing. And even specifying Home gets a not-found-here kind of
message.
The Services application shows that both smb and nmb are running.
So what's wrong, where might the fault lie, and how do I correct it?

Questions regarding dual booting with Windows 8.1
by Sudhir Khanger
Hello,
I have to install Windows 8.1 so that Dell technician can troubleshoot my system. I have not installed Windows in years, so, I wanted to confirm the process before destroying my system.
I will create a 50GB partition for Windows 8.1. I installed Fedora with automatic partitioning. As a result, home partition which I will resize is in middle. Is it okay to resize the partition in the middle to install Windows?
$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
nvme0n1 259:0 0 238.5G 0 disk
├─nvme0n1p1 259:1 0 200M 0 part /boot/efi
├─nvme0n1p2 259:2 0 1G 0 part /boot
├─nvme0n1p3 259:3 0 197.3G 0 part /home
├─nvme0n1p4 259:4 0 20G 0 part [SWAP]
└─nvme0n1p5 259:5 0 20G 0 part /
Once I have installed Windows, it will probably overwrite Grub and possibly UEFI entries. Do I simply have to reinstall the Grub for Fedora to start detecting it as a second OS.
grub2-install /dev/nvme0n1
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
Do I have the process correctly understood?

piping
by Patrick Dupre
Hello,
It is not a fedora question, but I am sure that somebody can help me.
I do:
my_sort files.asc > new_file.asc
and then
gawk -f file.awk -v sampl=T new_file.asc
to get what I want.
how can I do the same in a single command with a pipe (and not generating
the new_file.asc) ?
Thank.

I had the same problem when (finally) deciding to reconfigure a server
to use NetworkManager instead of the old network service.
I manage to make it work with a "drop-in" configuration file for
NetworkManager-wait-online.service that replaces the call of nm-online
by waiting for all the wanted routes to be up and that a gateway is
reachable. See attachment.
For this server it's really long, and waiting for the routes is not
sufficient at all:
Dec 17 12:46:37 xxx bash[1047]: Network Manager Wait Online routes
took 9 seconds
Dec 17 12:47:07 xxx bash[1047]: Network Manager Wait Online gateway
took 30 seconds
Dec 17 12:47:07 xxx systemd[1]: Started Network Manager Wait Online.
