According to user reports on grub-devel mailing list about grub-mkrescue
ISOs, the boot flag must not be set on the protective MBR partition.
But some BIOS implementations wont't regard the medium as bootable if there
is no boot flag set at all.

The compromise that finally worked for those who tested, was to create an
MBR partition of type 0x00 starting at LBA 0, having only one block, and
bearing the boot flag.
The tested EFIs and operating systems still recognized GPT if an additional
partiton of type 0x00 was present. But doubts remain. YMMV.

The decision with grub-mkrescue was to omit the boot flag by default
and to leave it to the user whether add-on xorrisofs option
--mbr-force-bootable shall cause the boot flag to be set on a dummy
partition.


Have a nice day :)

We live in an imperfect world, though this isn't exactly what you'd call

Maybe the VLC people would argue this isn't a bug, as you might be

up screen real estate by closing the video's window on the source machine.

Re: grub tries to read outside of a disk.

2018-11-23 Thread Daniel Fishman

On 23/11/2018 03.09, Daniel Fishman wrote:

Hello,

I am trying to install Debian on a 4TB external HDD, and want to be able to
boot it both on UEFI and BIOS systems. Using a simple BIOS/GPT configuration
(GPT partitioning with BIOS boot) didn't work out - after receiving some
important tips from this mailing list about problems that I had with this
configuration I succeeded to boot on BIOS system, but not on UEFI system.
Therefore I tried to combine BIOS+UEFI boots by creating both EFI and
BIOS boot partitions, and then installing grub into both. Here is how the
HDD was partitioned:

[root@arch]# parted /dev/sdb print
Model: WD Elements 25A1 (scsi)
Disk /dev/sdb: 4001GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
Disk Flags:

Number  Start   End Size    File system Name  Flags
  1  1049kB  2097kB  1049kB    bios_grub
  2  2097kB  202MB   200MB   fat32 boot, esp
  3  202MB   714MB   512MB   ext4
  4  714MB   8714MB  8000MB  linux-swap(v1)
  5  8714MB  4001GB  3992GB  ext4

Partition 1 is intended for BIOS boot partition (for Stage 1.5 loader),
partition 2 is the EFI partition, partition 3 is intended for the /boot
(as was suggested previously on this mailing list) so that grub-related
files will be located inside the 2TB limit and therefore be accessible to
Stage 1.5 loader in BIOS mode, partition 4 is a swap, and 5 is the /.

I performed Debian installation on a UEFI machine, and after an installation
succeeded to boot the HDD. After that I installed grub into MBR:

grub-install --target=i386-pc --recheck /dev/sdb

Then I tried to boot on BIOS machine, and got the following error from grub:

"error: attempt to read or write outside of disk 'hd0'"

and was dropped into grub's rescue shell. I tried the following command:

ls (hd0,gpt3)/

which listed the expected contents of the /boot partition. Then:

set root=(hd0,gpt3)
set prefix=(hd0,gpt3)/grub
insmod normal

and again I get the error message

"error: attempt to read or write outside of disk 'hd0'"

As far as I could find, usually this kind of an error happens when
grub's files are located on a partition which is far from the
beginning of a disk, but in my case this is not so. And since grub
can list contents of a partition from a rescue shell, then it has
access to the file system. Then what is the problem here?


Eventually I succeeded to solve the problem, though I still don't understand
the reason for it - and maybe the solution will be useful for somebody else.

I repeated the whole installation process from the beginning, and this time
used a bit different partitioning scheme, where locations of /boot and EFI
partitions were switched, so that /boot partition (with all the files needed
by the grub) are now located immediately after BIOS boot partition, or in
other words:

[root@arch]# parted /dev/sdb print
Model: WD Elements 25A1 (scsi)
Disk /dev/sdb: 4001GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
Disk Flags:

Number  Start   End SizeFile system Name Flags
 1  1049kB  2097kB  1049kB  BIOS boot partition  bios_grub
 2  2097kB  539MB   537MB   ext4Linux filesystem
 3  539MB   749MB   210MB   fat32   EFI System   boot, esp
 4  749MB   9339MB  8590MB  linux-swap(v1)  Linux swap
 5  9339MB  4001GB  3991GB  ext4Linux filesystem

The idea was that maybe somehow (maybe due to a buggy BIOS) the fact that EFI
partition was located before /boot partition confused BIOS and therefore
prevented it from being able to access files on /boot partition.

There was a number of other small things that I did somewhat differently
(for example, this time a partitioning was done with gdisk instead of with
parted, and I think that I used a bit older Debian's installation media),
but they don't seem significant enough.

openvpn over ipv6 /65

2018-11-23 Thread tony
Hi,

I have a Stretch VPServer with a /64 netbloch, of which only the first 2
addresses are used. I've been struggling for some time to get the right
stanza to split that into two /65s, using the upper half for openvpn.

There are many 'quick config' tutorials on the web, but none seem to
suit my objectives, the most enlightened being
https://community.openvpn.net/openvpn/wiki/IPv6, but I'm tripping over
the stanza:

### check this on your OS!
# ifconfig igb0 inet6 2001:db8:0:123::/64 -alias
# ifconfig igb0 inet6 2001:db8:0:123::/65
###
### re-assign the other aliases previously set under the /64 block
# ifconfig igb0 inet6 2001:db8:0:123::dead/128 alias
# ifconfig igb0 inet6 2001:db8:0:123::ea:beef/128 alias
# ...

which seems to apply to FreeBSD.

Could some knowledgeable person please give me the equivalent contents
and where to put them for Debian Linux.

TIA, Tony



Still unable to restart networking on Debian 9 text mode only

2018-11-23 Thread Luciano Andress Martini
Good morning,

IMPORTANT: Network Manager was not being installed automatically by
the Debian DVD when I do not mark the graphical interface.

I tried a fresh Debian install without graphical interface but using
the graphical installator I am running Debian 9.6.

Then I edited /etc/network/interfaces and restart the system, to see
if the ip was changed. And yes, it worked. So this file is still being
used in some way - humm that seems to be the correct place to
configure my interface isn't?

Well, I edited it again, now to try change the ip but without
restarting the system - like in all servers real situation, you don't
want to go after the server. First of all I tried all this solutions:

#systemctl daemon-reload
(nothing happens ip didnt change)

#systemctl networking restart
(the ip did not change and the connection breaks you need to go
phisicial and ip address shows the same ip configured)

#nmcli connection reload
nmcli connection reload The program 'nmcli' is currently not installed.
You can install it by typing: apt install network-manager
nmcli: command not found.
(my comment: well it seems NetworkManager was not installed is that right?)

# nmtui
The program 'nmtui' is currently not installed.  You can install it by typing:
apt install network-manager
nmtui: command not found

The solution that i found is this (but i think that is not a real solution):

ip address delete theoldip/mask dev enp0s3
ifdown enp0s3
ifup enp0s3

But if for example i do it partially, it does not work... for example:

ip address delete theoldip/mask dev enp0s3
ifup enp0s3
The interface is already... blabla

ifdown enp0s3
ifup enp0s3
(a new ip is added to the interface, but now two ips are configured
and the network is broken again)

Is that a bug?

I'd check first that some other addresses from this /64 range are routed
by your VPS provider.

Yep.

Ad-hoc configuration:

# ip a d igb0 2001:db8:0:123::/64
# ip a a igb0 2001:db8:0:123::/65

As for the persistent configuration, that depends on the contents of
/etc/network/interfaces. Can be static (it's straightforward then),
DHCPv6 (you won't be able to do the split) or RA (ditto).

An excellent news. Let's hope that Debian continues to behave this way.

So, in plain English, you have ifupdown installed.

And it should not. ifupdown provides networking service, and
"daemon-reload" forces systemd to re-read own config only, not to
restart services.


> #systemctl networking restart
> (the ip did not change and the connection breaks you need to go

"networking restart" invokes "ifdown" first, and "ifup" next.
And systemd restarts most of the network services by dependency.
The problem is - once they invoke ifdown, there's no network connection
to invoke "ifup", hence you have no network-listening services.

Do it from BMC/ILOM/HMC (it's not a server if it does not have one), or
install screen/tmux and do it from there.

ifdown/ifup combo should be sufficient. Just don't do it via plain ssh
connection.

ifup/ifdown have their own special way to track which interface was
touched by them. ifup will rightfully refuse to bring network interface
UP if it considers that it's UP already.

You mean, two new IPv6 ips? Can you provide a 'correct' and a 'broken'
example via 'ip a l' please?
And, while we're at it, the contents of /etc/network/interfaces?

Short of the last part everything else can be classified as an

Yeah, my own tests always gave me that too, so I decided not to post
my results here.  Apparently the only way I can *test* this and *post*
my results would be if I use a .deb file that does *not* correspond to
a package that is known to apt on my system.  Which would mean either I'd
have to find a random third-party repository that has a *small* package
that I could download and install with apt-get install ./ for testing
purposes, or I would have to purge my web browser, purge the Google
repository from my sources.list.d, apt-get update to purge it from the
cached lists, and then repeat the basic procedure of installing
google-chrome-stable from scratch.

I was not willing to do all of that just to prove people wrong on the
Internet.  I have some limits.

If someone still claims that it "doesn't work", then for the love of RMS,
post:

 * which VERSION of Debian you are using,

 * the EXACT command you used, and

 * the FULL and EXACT output of that command.

One person who claimed it "didn't work" went through those steps and
discovered that the wrong command had been used.

/etc/network/interfaces is the primary, supported means of configuring
network interfaces in Debian.  It's the best choice for standard server
and workstation setups.

Network-Manager may also be installed (it's optional).  As you've already
seen, it is installed when choosing a "desktop environment" during the
Debian installation, and skipped if no DE is chosen.  N-M is apparently
the tool of choice for configuring wireless interfaces on laptops.

Interfaces that are configured in /e/n/i are skipped by N-M.  Thus,
you could think of it as "/e/n/i has priority, and N-M gets whatever
/e/n/i didn't get".

Then there's some bizarre systemd network interface thing.  It's not
used by default in Debian.  I can't imagine anyone ever using it.
You can simply ignore it.

Apart from Dan's (which is good advice, anyway), to be able to help you,
people here at least need to know:

 - do you already have installed some GNU/Linux distribution on your
   laptop? If yes, we could find out more about your wireless
   hardware, and what would be necessary to get it running.

 - Which distribution you have installed/want to install? (I'm assuming
   it is some Debian or one of its derivatives -- after all, you are
   posing your questions in a Debian mailing list).

 - What kind of laptop you have (brand, model number, etc.)

Cheers... and keep on hacking :-)

Re: Still unable to restart networking on Debian 9 text mode only

Thank you Greg i would not like to use NetworkManager, i just tried it
because all the other ways that i tried did not worked in new Debian
Versions, after a fresh install so i am searching for a correct way of
doing things.. (i read documentation, but maybe i am missing
something)

ifdown and ifup work partially instead of changing the ip, and it is
adding a new ip to the interface.

service networking restart - just brokes the network connection.

Re: Still unable to restart networking on Debian 9 text mode only

2018-11-23 Thread Luciano Andress Martini
Additional information - Again Debian 9.6 Fresh Install without
graphical interface:

cat /etc/network/interfaces:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug enp0s3
iface enp0s3 inet static
address 10.5.0.2/24
gateway 10.5.0.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 8.8.8.8
dns-search neoconsig.local

Just changed 10.5.0.2 to 10.5.0.3

#ifdown enp0s3
#ifup enp0s3


Results in two ips configured instead of changing it:

#ip a
2: enp0s3:  mtu 1500 qdisc pfifo_fast
state UP group default qlen 1000
link/ether 08:00:27:7a:16:16 brd ff:ff:ff:ff:ff:ff
inet 10.5.0.2/24 brd 10.5.0.255 scope global enp0s3
   valid_lft forever preferred_lft forever
inet 10.5.0.3/24 brd 10.5.0.255 scope global secondary enp0s3
   valid_lft forever preferred_lft forever
inet6 fe80::a00:27ff:fe7a:1616/64 scope link
   valid_lft forever preferred_lft forever


Now lets restart the system and try it again but now using systemctl
restart networking:

After the full reboot the ip changed to 10.5.0.3, respecting
/etc/network/interfaces.

So, Lets try to change it again from 10.5.0.3 to 10.5.0.2

#systemctl restart networking
(connection just disconnected instead of changing the ip)
#ping 8.8.8.8
(eternally waiting...)
#ip address
Still shows the correct information (the ip did not change)

Possible BUG: Unable to change the ip of network interfaces without reboot in text mode

2018-11-23 Thread Luciano Andress Martini
I am not sure if my answers are reaching the users because i did not
received it back so sorry to creating a new thread, but i think this
is very important, please follow this steps to emulate it:

1- Install Debian 9.6 without graphical interface.
2- Try to change the ip in /etc/network/interfaces
3- Run systemctl restart networking
ping 8.8.8.8
(network stopped working!)
If system is restarted everything is ok again, and ip is changed properly .

New try, now with ifdown and ifup:
1- Install Debian 9.6 without graphical interface.
2- Try to change the ip in /etc/network/interfaces
3- Run ifdown enp0s3
4- Run ifup enp0s3
5- That's right ,but now you have two ips configured instead of changing it.

Is this is expected, i am so sorry for boring you, i will get out of
here the faster as i can.

SSH & X11 forwarding

2018-11-23 Thread Martin
Hi list members,

I have not used X11 over ssh for years now. But today is the day! And it does 
not work
The remote console tells me 'Xt error: Can't open display: :0'.
X11Forwarding is enabled on client and server, 'xhost +' on the client, DISPLAY 
is set. IPv6 is disabled on both ends with sysctl and in sshd_config. Client 
runs with xfce.

What did I miss?

And that's where you're doing it wrong.
ifdown tries to remove the IP listed at /etc/network/interfaces first,
and to bring the interface down next.

Basically you've just asked ifdown to remove a non-configured address,
but do nothing for the configured one.


> #ifup enp0s3

A correct sequence to do this is:

ifdown 
edit /etc/network/interfaces
ifup

Please do not do this unless you have BMC/ILOM/ASMI/direct console

This should work by default. Any graphical application should then show on

Running this from Windows, you need an extra X-Server.

Hope this helps.

Every position in this list seems redundant to me, short of xfce part.
You definitely do not need to run X server at the host to which ssh connnects 
to, X11 Forwarding works perfectly via IPv6, and you definitely do not need to 
set $DISPLAY by hand in the ssh connection.

A wild guess - installing xauth. And running sshd -Xv.

No, it's all static:

auto eth0
iface eth0 inet static
address 188.246.204.210

Thanks for the details.

I see. This is actually the info needed here (actually the driver is probably
called "iwlwifi-3160-17", see below).

> But I didn't had the disc with it as the system asked me to insert it.
> I have done my installation using NET INSTALL and got all the packages from
> the Wired connection.

Asking "apt-file" (this is a very useful command, which is found in a
package with the same name):

  tomas@trotzki:~$ apt-file search iwlwifi-3160
  firmware-iwlwifi: /lib/firmware/iwlwifi-3160-12.ucode
  firmware-iwlwifi: /lib/firmware/iwlwifi-3160-14.ucode
  firmware-iwlwifi: /lib/firmware/iwlwifi-3160-16.ucode
  firmware-iwlwifi: /lib/firmware/iwlwifi-3160-17.ucode
  firmware-iwlwifi: /lib/firmware/iwlwifi-3160-9.ucode

(Apt-file searches for packages containing a file with that name) reveals
that iwlwifi-3160-17.ucode is contained in a package named "firmware-iwlwifi"
(the suffix .ucode suggests that those are "microcode files", i.e. firmware
to be loaded onto the processor embedded in your wifi hardware.

So installing the package "firmware-iwlwifi" should get you going.

Note that the package itself is in the non-free repository (hardware vendors
sometimes distribute non-free software and don't document their hardware
in a way that would allow us to write software for it, alas). So possibly
you would have to enable the non-free repository. Don't hesitate to ask
if you are unsure.

Assign some other IPv6 address from your range to your VPS.
Ensure that it's reachable from the outside world.
For instance, I do not get any response from your gateway while I'm
pinging 2a03:9800:10:54::dead (which you do not have), and get a reply
from 2a03:9800:10:54::2 (which belongs to your VPS).

That simplifies things greatly.
Replace this:

iface eth0 inet6 static
   address 2a03:9800:10:54::2
   netmask 64
   gateway 2a03:9800:10:54::1

with this:

iface eth0 inet6 static
   address 2a03:9800:10:54::2
   netmask 65
   gateway 2a03:9800:10:54::1

Leave all the other entries intact.
Then invoke this as root (one-time only):

ip a d dev eth0 2a03:9800:10:54::2/64
ip a a dev eth0 2a03:9800:10:54::2/65
ip ro d default via 2a03:9800:10:54::1


> So what is igb0?

A name of interface that's used in OpenVPN documentation. Yours is called eth0.


> What do you mean by ad-hoc and persistent configuration?

ad-hoc means that you're using certain OS binaries (in this case - ip)
to create a network configuration that does not survive the reboot.
persistent means the opposite - you're trying to create a configuration
that should reproduce itself after the reboot (in this case - e/n/i).

If you are not logging in with 'ssh -X ' or 'ssh -Y ' then you
are not X forwarding over ssh.  In particular, X forwarding does not
require the Xserver to listen for any connections.  As others have
pointed out, you should be able to ssh in then execute the command for
graphical application and that application should present itself on your
desktop, from where you initiated the ssh connection.

It sounds like what you are doing is using ssh to access the remote
machine and then launching whatever X application you need in such a way
that it simply connects back directly to the X server on your machine
rather than traversing the ssh tunnel.

If you have NetworkManager installed and connection was already setup
and working, this task is accomplished by only 2 commands:
    # nmcli con mod "MyConnectionName" ipv4.addresses "10.0.0.5/24"
    # nmcli con up "MyConnectionName"
That's it. After that your ip address will be set to "10.0.0.5". No need
to take your interface down, restart networking or reboot system. And of
course this method works over ssh connection.
Any information about connection names, available configurable
properties, etc could be done via nmcli with bash auto-complete being a
convenient helper.

NM is great. I really don't understand why people think it's only for
systems with GUI and hate it, while having trouble with editing /e/n/i
for anything more complex than changing ip address.

  This will need to be repeated at every reboot, better to use `up`, for
 example:

iface eth0 ...
...
gateway ...
up ip -6 addr  ..

  "up" will run the given command after the interface is brought up, as
 per "man 5 interfaces".

No, it won't. OP has two stanzas regarding eth0 in e/n/i already - one
for inet and another one for inet6.
The whole point of this exercise is to get persistent configuration for
/65 netmask *and* to avoid ifdown/ifup sequence to implement it now.
And, of course, do the thing without the reboot.

Apache Segmentation Fault

2018-11-23 Thread H.
Hi,

I have a web server running Testing with apache 2.4.37 and php 7.3. The
purpose of the server is to run owncloud. However, after the nightly
restart the server stops working. The logs show the following:

/var/log/apache2/error.log.1
[Fri Nov 23 00:00:01.526101 2018] [mpm_prefork:notice] [pid 2858]

These segmentation faults keep going so that the error.log file grows
to hundreds of MB within a few hours.

When I do "service apache2 restart" the server works properly again
until the next nightly restart.

Any idea what could cause this problem?

Package versions:
libapache2-mod-php7.3/testing,now 7.3.0~rc4-1 amd64
php-apcu/testing,now 5.1.12+4.0.11-2 amd64
php-redis/testing,now 4.2.0~rc2-1 amd64
php7.3-opcache/testing,now 7.3.0~rc4-1 amd64
certbot/testing,now 0.28.0-1 all

First I had the opcache enabled in /etc/php/7.3/apache2/php.ini, but
then I disabled it since many people reported issues with opcache
causing segfaults. However, the problem still persists. I also tried to
switch the memcache setting of owncloud from APCu to Redis, but also no
effect. Owncloud's cron.php is executed via www-data's crontab.

I also ran "certbot renew", but it does nothing because the server's
certificate is still valid and thus the server keeps running.

Best regards,
Dino

  You're right; I'm clearly not having a good day!  Thank-you

Re: SSH & X11 forwarding

2018-11-23 Thread der.hans

Am 23. Nov, 2018 schwätzte Martin so:

moin moin,

please don't 'xhost +', that should not be needed.

The application being tunneled comes from localhost, so you shouldn't need
any xhost adjustment.

ciao,

der.hans


Hi list members,

I have not used X11 over ssh for years now. But today is the day! And it does 
not work
The remote console tells me 'Xt error: Can't open display: :0'.
X11Forwarding is enabled on client and server, 'xhost +' on the client, DISPLAY 
is set. IPv6 is disabled on both ends with sysctl and in sshd_config. Client 
runs with xfce.

What did I miss?

Re: Unable to boot BIOS/GPT system.

If the EFI firmware can boot in legacy BIOS compatibility mode, it may

According to user reports on grub-devel mailing list about grub-mkrescue
ISOs, the boot flag must not be set on the protective MBR partition.


Yes, the protective partition should have the boot flag cleared for 
compliance with the GPT specification. But that's the theory, and there 
is the practice. For example I have come across an UEFI firmware 
implementation on a very old Intel board which required the boot flag to 
be cleared for EFI boot but set for legacy BIOS boot...



But some BIOS implementations wont't regard the medium as bootable if there
is no boot flag set at all.


IME, many Dell and HP's are among these.


The compromise that finally worked for those who tested, was to create an
MBR partition of type 0x00 starting at LBA 0, having only one block, and
bearing the boot flag.


Indeed it worked for me too, and even allowed booting either in EFI or 
BIOS mode with the above board. At least until parted (or, I guess, any 
other libparted-based partition manager such as partman, the 
partitioning program part of the Debian installer) is used on the disk 
and resets the partition table to a standard protective MBR. Same if you 
set up a hybrid MBR with gdisk. So make sure to never use parted & Co. 
on such a disk or make sure you set the boot flag again afterwards.




Any directional antennas recommendations?

2018-11-23 Thread Hubert Hauser
Hello!

I need to connect to a distant Wi-Fi network. I consider buying a
parabolic antenna. I want to have 10 km range and long amplification.
Will TP-Link TL-ANT2424B be a good aerial?

It's doubtful that you can reach a 10KM network with any kind of antenna 
unless there is an equal one at the far end. Then you might try the 
parabloic at each end.

I'm not a full expert on https, but think that the encryption aspect  might
prevent determining file types.

here goes something of the code that works with http

I'm not sure you *know* file types, due to the Encryption.

In fact, isn't this one way people get around Political Censorship?

Para poder filtrar tráfico HTTPS, hace falta configurar los clientes
para utilizar el proxy para tráfico HTTPS.  Además, te hace falta
configurar un certificado SSL para squid e instalar ese certificado en
los clientes y también configurar los clientes para confiar en ese
certificado.

No es posible hacer de proxy tráfico HTTPS de manera transparente.

Saludos,

-Roberto
