upgrade gnome-3.16.2-r2 -> gnome-3.18.2

Hi List,
Just by chance. Will upgrade from gnome-3.16.2-r2 to gnome-3.18.2 be smooth?
Everything in my current Gnome version is working just fine. On the 
other hand, don't want to stay behind.
Will the new version improvements compensate a eventual pain?
Luck from your experience.

mdadm RAIDs on 4k drives etc

I know, there is a linux-raid-ML ;-)
I unsubscribed there a few months ago.

What I would like to discuss and ask here:

Is it problematic to have both 512-byte- and 4k-sector-drives in one
RAID array?

I have that case at a customer where the partition map was copied over
(sfdisk -d) from an old to a new drive.

Now we have misaligned raid member drive with 4k and the older member
with 512bytes.

Additional question here: which version to use?
0.90 for booting, right? As far as I understand the manpage the "-e"
switch does not have much to do with aligning or so.


I plan to add another new 4k drive to the RAID1 array after partitioning
it correctly aligned. Then let it sync, remove other disk ... partition
correctly ... etc etc

Virtualbox not displaying USB devices

I'm running Windows-7 in Virtualbox, everything worked OK yesterday but today Virtualbox does not see any
USB devices. 
I have a USB label printer and it is recognized by Gentoo host: 

[ 6455.295503] usb 3-1: New USB device found, idVendor=04f9, idProduct=2028
[ 6455.295505] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3

[ 6455.297544] usblp 3-1:1.0: usb_probe_interface - got id

Setting in Virtualbox: "USB 2.0 (EHCI) Controller" is Enabled.

I'm in "vboxusers" group.

fd <at> clinic-amd ~ $ groups
wheel uucp audio cdrom cdrw usb users scanner fd plugdev vboxusers

What else should I checked for?

Recently I just upgraded to "openssh-7" but that should have nothing to do with Virtualbox and USB.
I connected the QL-570 (USB printer) to my backup machine and VirtualBox recognize it OK

unexpected interrupt


I still cannot reply from the web interface on gmane.
And this is an different approach suggesting for Peter's Chrony issues
so it might warrant a new thread anyway.

The installation-default file causes the start-stop-daemon to catch an
unexpected interrupt and report an error, even though the chronyd
continues to run.

Any time I run 'strace -ff -o/tmp/chronyd.strace /etc/init.d/chronyd
start' the init process runs normally and I'm left with scores of trace
files, none of which help because the stray interrupt wasn't detected

So, a while back the excellent tools of trace-cmd and kernelshark (part of
trace-cmd) were added to the portage tree.

Here is a little 'diddy' that might get you going [1]. Also, there is much
posted on the use of ftrace, trace-cmd and kernelshark. These very powerful
tools take a while to master. Often, I try to recreate deep performance
problems on minimal system, just to reduce the amount of data one has to parse.

tc filter add ... fails


it seems I might be missing some kernel modules:

| heimdali ~ # tc filter add dev ppp0 parent ffff: protocol all prio 10 basic police mpu 64 rate 16000kbit
burst 10kb action drop
| RTNETLINK answers: Invalid argument
| We have an error talking to the kernel
| heimdali ~ # 

This is a filter shorewall would add.  I have enabled options as shown
in [1].  How can I find out which modules I'm missing, or what else went

Bug-reporting best practice? Xen/Gentoo -- Preparing to log interrupt info sometime after feb. 2016.

Hi all, I'm not a developer but I would like to set up my Xen system to
get bug reports as useful as possible. At present I am logging the xen
console via serial port, and I am running Xen compiled from gentoo
ebuild with "debug" use flag. Is there anything more I need to set up to
be able to collect as much useful info as possible?

At present, this is my xen command line:
xen_commandline        : ssd-xen-debug-marker console_timestamps=date
loglvl=all guest_loglvl=all sync_console iommu=1,verbose,debug
iommu_inclusive_mapping=1 com1=115200,8n1 console=com1 dom0_max_vcpus=4
dom0_vcpus_pin=1 dom0_mem=8G,max:8G cpufreq=xen:performance,verbose
tmem=1 sched_smt_power_savings=1 apic_verbosity=debug e820-verbose=1

(yes, I know, 8G for dom0, well, it is also acting as file server, I
want to keep as much of the file-system in cache as I can )

Any changes I should make for maximally useful bug-reports?

This is in preparation for the 4.7 release (april 2016 I gather) . I
have some PCIe cards that are acting up, something to do with
interrupts. I see some activity on that front right now, so I've decided
to be an early adopter of 4.7, to be able to help as much as possible,
maybe get any tweaks I might need for my system done in the source.

I'm running gentoo, and have tried installing xen-*-9999 from the
virtualization overlay, but it fails, seems it is trying to fetch the
qemu sources twice, and failing.  Is it me doing something wrong? Use
flag "system-qemu" does not help.

Weird "df" output

  I'll admit that my system setup is a bit unusual.  A long time ago, in
a place far away, hard drives were small, compared to today's standards.
The usual unix practice of multiple seprate partitions was not feasable
for me, but I did want to keep root on its own partition.  So I
compromised with a small / partition, with empty /home, /opt, /var,
/usr, and /tmp directories.  Their real equivalents are bind-mounted
from a much larger partition.  I just re-did my oldest machine.  It has
a primary partition 1, which covers the entire hard drive.  The /
partion on /dev/sda5 is approximately 500 megabytes (YES!).  There's a
3.8 gigabyte swap partion /dev/sda6, and the rest of the drive is
/dev/sda7.  Here's the relevant portion of /etc/fstab...

/dev/sda5               /           ext2     noatime,async      0 1
/dev/sda7               /home       ext3     noatime,async      0 1
/home/bindmounts/opt    /opt        auto     bind               0 0
/home/bindmounts/var    /var        auto     bind               0 0
/home/bindmounts/usr    /usr        auto     bind               0 0
/home/bindmounts/tmp    /tmp        auto     bind               0 0
/dev/sda6               none        swap     sw                 0 0

...and the output from "df"...

openssh-7.1_p1-r2 won't allow "nxserver" to connect [continued]

I have exactly the same problem mentioned in this thread. I think something changed and broke the authentication during an update. i found this message by Googling and just joined the mail list to ask for help. I have done everything mentioned in the thread, and here's where I'm at: (it worked fine before some regular update broke it)

        - Make sure your sshd_config AuthorizedKeysFile in sshd_config is set to authorized_keys.
    (this should be a filename not a pathname+filename)
  - Make sure you allow ssh on localhost, this could come from some
    restriction of:
      -the tcp wrapper. Then add in /etc/hosts.allow: ALL:localhost
      -the iptables. add to it:

What do you use for appliances with old SSL?

It seems like modern browsers don't have the option to support old crypto, eg on firefox setting security.version.tls.min to 0 still blocks SSLv3. What do you use to access old equipment?

systemd-logind problem

I am running systemd-226-r1 and am having some strange problems with
systemd-logind.  It gets into some state where it can take 20 seconds to
login to the box via ssh, if I restart systemd-logind or rather stop and
start -- restart has no effect -- then it works for some unknownperiod,
but then it dies again.  Any way to fix more permanently -- I saw some
discussion a while back, but I never saw a resolution.

Thanks in advance for any ideas.
