VPN l2tp+ipsec: not work with last kernel 4.11.3-200
by Dario Lesca
Yesterday I have update my fedora 25 and after reboot VPN l2tp+ipsec do
not work anymore.
The connection happens without problem, the routing are set correctly,
the DNS (UDP protocol) and ping (ICMP protocol) to remote host work.
Only the access to some server, like ssh or smb:// (TCP protocol) do
not work, in this case, if I monitoring on remote server with tcpdump,
none arrives.
If I reboot with previous kernel (4.10.17) all work fine.
Some suggest?
Many thanks

Difficulties at very first steps with f25kde ...
by Walter H.
Hello,
my older computer is a Core2Quad with 4 GB RAM had a hard disk with a
Windows 10
what I did:
- I plugged this harddisk as harddisk 2 and added an empty harddisk as
harddisk 1
- I downloaded Fedora 25 KDE (Fedora-KDE-Live-x86_64-25-1.3.iso) and
burnt this to a DVD
- I installed this onto harddisk 1, the boot menu entry for the 2nd
harddisk with Windows 10 was added automatically
I gave fixed IPv4 (an RFC1918 addr) and IPv6 (my HE tunnel
range) addresses
- after the first login I had to enable sshd - why isn't this
automatically? - with
systemctl enable sshd
systemctl start sshd
now I could do SSH from my newer computer (Windows)
- I did an yum update and this updated more than 800 packages and
downloaded nearly 1 GByte
after this I rebootet
- I successfully installed postfix as MTA and logwatch, works as
expected - why is the logwatch mail 'precedence bulk'?
- I also needed the graphical connection and found this:
https://www.server-world.info/en/note?os=Fedora_24&p=desktop&f=7
there I have a strange phenomen
after the connection with mstsc, I get a window where I can select
between Xvnc and Xorg, when selecting Xvnc and entering userid and
password
the window is closed and session blown away ...
when I select Xorg and enter userid and password the window stays
'green' forever

The CGROUP error makes no sense because /usr/lib/systemd/systemd clearly
does exist.
User nvtest is used to run testbeds via ssh, all those errors almost
certainly happened when a test run was using my system as a remote
test target and logging in via ssh for each individual test to run
a specific remote program (not a normal shell, though that remote
program usually starts a shell).
Meanwhile, despite all these silly errors in the log, the actual
test run appeared to work fine.
What new nonsense hath systemd wrought?

Fw: Systemd keeps trying to re-open an already active LUKS volume

Begin forwarded message:
I forwarded this to test since F26 is still not released, and they are
deciding whether to release this week. You are much more likely to get
an answer to your question there.

Subject: Systemd keeps trying to re-open an already active LUKS volume
Hi,
I need a piece of advice concerning an encrypted root partition on
Fedora 26. I'm running a custom manual setup created using dnf.
Further context:
* The installation procedure is outlined in this tread -- and quite
likely irrelevant to this question anyway:
https://lists.fedorahosted.org/archives/list/users@lists.fedoraproject.or...
* The disk layout is described in this comment:
https://bugzilla.redhat.com/show_bug.cgi?id=1297188#c2
Unlike Fedora 23 and 24, both of which booted just fine, Fedora 26 has
two glitches related to my encrypted LUKS root partition:
1. Dracut fails to automatically add the crypt module. It doesn't seem
to care about LUKS-related settings in /etc/default/grub and/or about
the fact that the system runs off an encrypted volume. I had to
manually add add_dracutmodules+="crypt" into /etc/dracut.conf, or else
I wouldn't get a password prompt on boot and the early systemd would
freeze waiting for the root partition to appear. It works normally with
add_dracutmodules+="crypt".
2. Possibly as a consequence of (1), systemd doesn't realize that the
root partition has been already activated and luksOpen'ed at boot time
and keeps trying to unlock it over and over. The consoles are spammed
by messages like this one, basically on every sudo invocation: Password
entry required for 'Please enter passphrase for disk cryptprdell-luks
(plainprdell)!' (PID 5492). Please enter password with the
systemd-tty-ask-password-agent tool!
Of course I tried to run the systemd-tty-ask-password-agent tool and
type in the password. But then systemctl --failed showed a failure in
systemd-cryptsetup(a)plainprdell.service, the auto-generated unit for the
LUKS volume. Presumably, journalctl revealed that the error message had
been "Failed to activate: Device or resource busy". Well, that's indeed
what happens when you try to open a LUKS volume that's already opened.
If I don't use systemd-tty-ask-password-agent at all, systemctl status
permanently shows "starting" and never reaches "running", because of
the LUKS volume it thinks it needs to activate. (I tried systemctl
disable, but nope, that had no effect.)
This appears to have something in common with an ancient bug from 2013:
https://bugzilla.redhat.com/show_bug.cgi?id=924581
Has anything changed (1) in the way Dracut finds out whether the crypt
module is needed (which worked at least up to Fedora 24) or (2) in the
way systemd generates its automatic units for encrypted volumes?
Something must have changed, but I have no idea what it is and how to
get the old behavior back. :-/
My /etc/default/grub and /etc/crypttab are attached. The current kernel
version is 4.11.0-2.fc26.x86_64.
Cheers,
Andrej

nfs problem
by Eyal Lebedinsky
I asked on AskFedora and got no response. Hoping this list is more active.
https://ask.fedoraproject.org/en/question/104010/nfs-showing-bad-data-f24/
I have a f24 workstation (nfs client). It is updated regularly.
The server is f19, so no updates there.
A problem started in the last few weeks. When I examine a file on the server it
looks OK. The file is updated every minute (collecting some stats) and 'tail' shows
the added lines as they arrive.
Examining the same file from the workstation is initially OK, but then, as the file
grows, I get binary zeroes at the end of the file. The same with tail, less, vi, etc.
The amount of zeroes seems to be the size of the extra data appended to the file.
'ls' shows the actual (full) size of the file. It looks like the utilities see the
correct size but bad data is delivered at the tail.
After a few minutes the full data is showing but then, as the file grows, again I get
zeroes for a few minutes.
Where do I look next?
TIA

I think this is a success result.
But why dnf is failed?
