AFAIK all AMD cpus support it.

So the stories about Red Hat trying to force everyone to use systemd and

I'm glad the evil spirits decided to depart.  Are you using networkmanager?
My resolv.conf says it was created by networkmanager.

It requires both CPU and motherboard support I believe.  The RAM
itself isn't much more expensive - really just reflecting the cost of
the extra capacity required.

If you were already going to buy a CPU or motherboard that supports
ECC then the incremental cost is almost certainly worth it IMHO.  The
problem is that if you weren't otherwise going to buy either then the
incremental cost to upgrade all the components to support it can add
up quite a bit.  So, when people say that it is just an extra $10-20
for the RAM, that bay be a rather misleading figure.

depends on your motherboard. ASUS boards support ECC officially. You
just put it in. With Gigabyte some boards support it, some don't - and
they don't advertise it. But on their forums are threads about it. Rest:
I have no idea.

After the last reboot I magically have got the right /etc/resolv.conf
with DNS servers IPs.

Even more strange is that it happened *without* my intervention:
just a few reboots (one was no enough!).

This, by the way, reminds me MS Windows very much.

I am afraid that you will not believe me, but I really did not changed
any configuration and have not (re)emerged anything after the previous
reboot. Why it did not worked then and does work now?

It is really very strange!

As I have already written, DNS resolution now magically works
again and without any intervention from my side: just a few
reboots (one was no enough!).

So, no need to re-emerge netifrc now.

My file is exactly the same, and it was changed on May 10, 2014 last time.
So, it could not be the cause.

This is my chrony.conf without all the commented out parts. 

server  64.6.144.6
server  67.159.5.90
server  67.59.168.233
server  204.62.14.98

server  69.50.219.51
server  209.114.111.1

driftfile /etc/chrony.drift

keyfile /etc/chrony/chrony.keys

commandkey 1

logdir /var/log/chrony
log measurements statistics tracking rtc


The last two lines are optional.  Use those if you like to be nosy and
watch it do its thing.  I still have ntpdate installed and use it to
check and see how close it is on occasion.  This is what I get from the
test:

root@fireball / # ntpdate -b -u -q pool.ntp.org
server 198.144.194.12, stratum 2, offset -0.003320, delay 0.10658
server 173.44.32.10, stratum 2, offset -0.003313, delay 0.07515
server 70.60.65.40, stratum 2, offset -0.003059, delay 0.09262
server 38.229.71.1, stratum 2, offset -0.001002, delay 0.09563
26 Jul 15:16:00 ntpdate[10232]: step time server 173.44.32.10 offset
-0.003313 sec
root@fireball / # 

I did a fair sized upgrade the other day and went to the boot runlevel
afterwards to restart the services that were updated.  I'm pretty sure
it has been doing its thing since then without me doing anything to it. 
I think you can use mirrorselect to find the best mirrors for your
area.  I can't recall the command but I bet a search of the Gentoo
forums would find it fairly quick. 

Looking at the howto, the only thing I do different is put it in the
default runlevel.  Unless I am in the default runlevel, there is no
internet access available anyway.  No internet access, no way to set the
clock anyway.  ;-)

Hope that helps.

That isn't right. It should say it's for interface eth0. At first I thought 
eth0 wasn't being brought up, but then you quoted replies from dig, so it must

Do you still have netifrc installed? Maybe it got lost in all that updating 
work. Try emerging it again anyway.

Do your 90-network-rules look like mine?

I am also.

After having a break, I decided to manually edit /etc/resolv.conf and then
chmod it to be unoverwrittable. But I had no chance to check this solution:
after booting my Gentoo computer once again, I have found out that now
/etc/resolv.conf was created *with* DNS servers IPs, and everything works
fine.

But it is *very* strange as I have *not* changed anything after my
previous reboot.
Absolutely.

Have I discovered a new Windows-like fix for a Gentoo system that can be called
"Just reboot it several times"?

But it did it just before the last update: it created DNS entries in
/etc/resolv.conf
from my /etc/conf.d/net file on every reboot. And now it "cannot do this magic"?

I too have been using chrony since before I can remember, when ntpd could only 
step the clock. Chrony just works - I haven't even bothered to look round for 
an alternative. As the docs say (somewhere or other), if you run any kind of 
mail service, you certainly don't want your clock to step backwards suddenly.

I didn't know Red Hat had taken over its maintenance - thanks for the info.

Have you checked that:

udev has not changed the name of your NIC and if it has, that your symlinks in 
/etc/init.d are correct.

Similarly, interface names are correct in your /etc/conf.d/net.

The syntax in /etc/conf.d/net is in line with /usr/share/doc/netifrc-
*/net.example.bz2


If all of the above are as they should be, then I'm running out of ideas.

The wiki article is from 2008 and doesn't seem "too wrong",
but the current ebuilds are a bit more up to date wrt.
default config and init script. The current template config also
contains very detailed instructions and is probably the best way
to get started. How much you need to set up depends on your specific
use case - pure client, steady/interrupted connectivity, server for
other machines on the LAN..

If you only want to be a client just add one or multiple servers
to the config and you are good to go; chrony works well pretty much
out of the box.

Then the problem is obvious - you have no nameserver entries as you
don't create any. The computer can't make them up by magic..

You need to create static nameserver entries because you use a static
(i.e. no dhcp) configuration. Add them to /etc/resolvconf.conf

If it still gets removed across restarts then you have some local
modification going on that does deletions you don't know about. You then
have too find them and turn them into something you do know about.

This does not help as /etc/resolv.conf is overwritten on every reboot.

if your system is using resolvconf to generate /etc/resolv.conf you
can use /etc/resolv.conf.head also with the same syntax, and its

That is all.

I tried to add here lines like:

  nameserver 8.8.8.8

but found out that this file is rewritten on every reboot.

My net try was to create /etc/resolv.conf.tail file
and put that line there but that did not help either.

OK, what does 'cat /etc/resolve.conf' shows?

It seems that you do not have a nameserver set up in your system?

I'm guessing that 'dig gmail.com' doesn't come up with an answer?

Do you then define the nameservers statically?

Do you use dhcpcd, or something else?

Unfortunaltely: No it doesnt.

I did a dd (as reported previously) of zeroes accross the affected
partition and dd fails to write ot the sector in question (IO error).

The selftest following again reports that sector as bad.

So...?

You did verify your settings where correctly used to generate
/etc/resolv.conf ? if not, append some known dns to that file this
way:
nameserver 8.8.8.8
nameserver 8.8.4.4

verify connection to your gateway and internet with ping.

 You are probably comparing different units.  The Start and End of fdisk 
 are 
 reporting sectors, each sector being 512 bytes.  Therefore if the LBA is 
 reported by smartctl in bytes, you have:

 4,288,352,511 ÷ 512 = 8,375,688.5

 which would place it within your swap partition.

 I would do this:

  swapoff /dev/sda2

  dd if=/dev/zero of=/dev/sda2 bs=512 conv=notrunc

  mkswap -L swap -c /dev/sda2

  swapon /dev/sda2

 and hopefully the problem will be gone when you run the next smartctl test.

nothing. As soon as someone tries to write on that sector, the drive
will map it out.

That means 'pending'. Nobody tried to write on it yet, so the drive had
no reason to 'reallocate' it so far.

I ask since only the FIRST bad sector is reported...:

...Since I have a read error in te very beginning of my hardisk...
Does this mean, that all coming smartcontrol tests will fail early and
the rest of the disc is NOT tested then?

[gentoo-user] Something went wrong with DNS, plz help!

[Grand Duet]

The first reboot after recent update of the system have
shown that I cannot open any webpage in Firefox.

More exactly, Firefox or my system cannot any more resolve
URL to IP address (sorry if I use wrong terms).

Thus,
   host gmail.com
gives:
   ;; connection timed out no servers could be reached

Nevertheless
dig @8.8.8.8 gmail.com
reports the corresponding IP adresses.

I have not changed any my network settings and my
/etc/conf.d/net file still contains list of my DNS servers
that contains server 8.8.8.8 as well but somehow it is
not enough any more. :(

During my last system update, I suddenly found that
I had to update about 150 packages, what was a little
bit strange as I update my system at least once a week.

I have attributed that to the remnants of gnome2 (now I am using
fxce4) that I have not cleaned completely and that is now going
to update. So, I deviated a bit from my usual system update routine
trying to fix that. Nevertheless, as to my view, during my system update
I did nothing to distroy the DNS lookup.

Luckily, I save my system update logs and now can attach
the last one to this e-mail.

Please, help me to recover my internet access,
as I still have to do a lot of real work till Monday
and have not enough time to investigate this problem
alone and without a proper internet access. :(

I think you are asking for the impossible :-)

NFS is not easy to set up, and even harder to describe. It is easy to
*use* once it's set up correctly - you just mount something and the only
difference to a local mount is you add an IP address.

NFS uses RPC to do some heavy lifting - I don't know how familiar you
are with this, so here's the quick version:

When you mount something locally, and need to use the mounted
filesystem, kernel calls are used to get at the data. This works easily
as the source disk is local and the kernel can get to it. With NFS, the
source disk is remote and it's the remote kernel that must do the
accessing. RPC is a way to safely ask a remote kernel to do something
and get a result that behaves identical to a local kernel call.
Obviously, this is rather hard to implement correctly.

The original RPC was written by Sun and other newer implementations
exist, like libtirpc - to support useful features like not being stuck
with only UDP. That's what the "ti" means - Transport Independant.

RPC has been in a state of flux for some time and I too have run into
init-script oddities as things change.

In my case, I have nfs-utils-1.3.0, and rc-update configuredd to start
rpc.statd. This works because

depend() {
...
need portmap
...
}

and in the init.d file for rpcbind:

depend() {
...
provide portmap
}

So rpcbind starts at boot time and all my nfs mounts JustWork

Looks to me like your problem is actually with rpc and more specifically
with what things are currently named today (which could be different to
yesterday). Unfortunately I don't know of a place where this is all
nicely described in a sane manner except inside the init files themselves.

chrony - no competition, even for servers. ntpd is way overrated,
unnecessarily hard to setup correctly, fragile and contrary to
popular belief not even that accurate, unless you use external
HW clocks. Chrony is maintained by Red Hat in cooperation with the
timekeeping code in the kernel.

Many many years ago I helped port openntpd to Linux. It was OK-ish at
the time and easier/less hassle than ntpd, but the portable version for
Linux stopped working reliably many years ago due to kernel changes.
IMHO it really should no longer be in the tree since it gives a false
sense of accuracy.

OK, so we know for sure now that the bad block was on your swap.  :-)

As Volker posted since you don't even get a "records in" / "records out" from 
dd, it seems that it is the first block.  You can verify with badblocks -c 1  
-e 1 -o my_bad_blocks.txt if this is so.

The mkswap -c command will identify and mark the badblock so that this is not 
used again for allocating data to it.

I have used ntp before, seen others recommend openntps.  At some point I
had trouble getting ntp and opentnpd to work so I started using chrony. 
It worked.  So, if you have trouble with the ntp options, give chrony a
try. 

My preference tho, ntp.  Both seems to be relatively active so flip a

that said: it is swap. You shouldn't have to do anything. Don't touch dd.

Howdy,

Which NTPd package would the list recommend using, ntp, openntpd, or
some other package?

openntpd seems to be easier to set up according to wiki.gentoo.org.

The list's advice would be much appreciated.

I seem to have the same version of wxGTK as you:
equery -q l wxGTK
x11-libs/wxGTK-2.8.12.1-r1

To the best of my knowledge, I did not experience any trouble building
the package in question.

threadpsx.cpp has these two references to 'thread.h':
wxPython-src-2.8.12.1/src/unix/threadpsx.cpp:27,29
#if wxUSE_THREADS

#include "wx/thread.h"

wxPython-src-2.8.12.1/src/unix/threadpsx.cpp:50,52
#ifdef HAVE_THR_SETCONCURRENCY
#include 
#endif

You may want to check if you have this file available on your system:
/usr/include/wx-2.8/wx/thread.h

I always try -j1 when anything fails to avoid troubling the list, however
it didnt help in this case. Did you suspect that thread.h is generated by
the package build process, or is there some other reason why parallel build
could cause this problem? AFAIK header files are not generated. I would
have guessed its a path problem or missing dependency.

Sorry for stuutering postings...overlocked this one:

Hi Mick,

got this:

#> /root>mkswap -L swap -c /dev/sda2
1 bad page
Setting up swapspace version 1, size = 6291448 KiB
LABEL=swap, UUID=71686035-fad3-427c-a3a5-c86ac6aefa2f


...so the dd-command hasn't triggered the remapping?

What do you suggest how to proceed?
New harddrive?
Or?

Hi MIck, 

thanks a lot for the clearification!

It also solves "the problem", that fsck does not report any problem
for the partitions...because there is none ;)
Which are good news.

I will clear the swap and report later what happens!

Best regards and have a nice weekend!

Postscript:

There's a comprehensive list of BBC stations at [1]. If anyone's interested 
and wants to use it, you'll have to fix a bug first. The 45 bookmark entries 
in the full BBC regional group are all missing a / character just before the

I've attached a fixed version hereto to save you the bother.

You are probably comparing different units.  The Start and End of fdisk are 
reporting sectors, each sector being 512 bytes.  Therefore if the LBA is 
reported by smartctl in bytes, you have:

4,288,352,511 ÷ 512 = 8,375,688.5

which would place it within your swap partition.

I would do this:

 swapoff /dev/sda2

 dd if=/dev/zero of=/dev/sda2 bs=512 conv=notrunc

 mkswap -L swap -c /dev/sda2

 swapon /dev/sda2

and hopefully the problem will be gone when you run the next smartctl test.

Hi Dale,

thank you very much for the explanations you gave...and for the hope

In the meanwhile I found ddrescue... :)

It took me five hours to copy the disk (1T) binaryly
