 Hi all,

 About mate again.
 As per this https://sunweavers.net/blog/node/45 is says that ebnd of
 Sept the packages must get fixed.
 I however still find it difficult to run caja which is primary
 file/folder manager.
 and many other applets too are crashing.
 Is there any schedule update which I can look forward to ?

As the address family for IPv4 is "inet" (vs "inet6"), you could say
"inet", but then it may not be so obvious that you were intending to
make a distinction between IPv4 and IPv6. So, perhaps "inet4" is not
so bad, or IPv4. Some go as far as to say "legacy". :)

On Linux, it would be best to get used to using the "ip" command
rather than "ifconfig". Issuing an "ip address" command will get you
all the configured addresses of the various families.

> Can anybody point me to a fairly short document that explains things like

If we restrict the domain of this question to source address
selection then reading around from this point may help:

http://linux-ip.net/html/routing-saddr-selection.html

> does one have precedence over the other,

Clearly if there is just one inet address and one inet6 address,
then which will be chosen depends on which family the destination
address comes from. i.e., if the destination is an inet6 address
then the source address will have to be an inet6 address as well,
otherwise no communication will be possible¹.

If the destination address has been directly specified then that's
simple enough to predict.

Usually though, we are just dealing with host names that we wish to
communicate with. A host name is going to be presented to the
system's hostname resolution system, which may return a result from
/etc/hosts or some other database. More usually though it's going to
go out to DNS.

The DNS may contain both A (IPv4) and  (IPv6) addresses with no
regard as to whether the client actually has a source address of the
matching family. That is, if you had a host with only inet6
addresses and you did a DNS query, you would still receive A records
as answers. If amongst the answers there were no  records then
you'd have no way to communicate with the destination when the
application tried to do that.

It's the getaddrinfo() function of GNU libc that decides which
destination address to select for use. You can find more details
about that with "man getaddrinfo".

By default, if there are both inet and inet6 family addresses to
choose from, getaddrinfo will choose the inet6 one. So, if your host
has at least one configured global inet6 address then your
applications will tend to try to connect to inet6 destination
addresses, where available.

You can configure getaddrinfo's address selection in /etc/gai.conf.
A very common desire is to prefer inet addresses over inet6 ones,
and so on Debian the configuration required to do that is shown in
/etc/gai.conf commented out.

An application can be told to use a specific source address, but it
is more common for applications to be allowed to use any address. In
that case for inet it will generally be a reasonably simple case of
using the routing table to determine which source address is
"closest" to the destination.

For example, suppose you have an interface that has the addresses
192.168.1.1/24 and 192.168.1.175/25 on it. When attempting to
communicate with 192.168.1.180 the routing table will show that this
is in the same network as 192.168.1.175/25 and that that is the most
specific address.

When it comes to inet6 it can get a bit more complicated, especially
as it is much more common to have several inet6 addresses, and
you've got whole new concepts like privacy addresses and deprecated
addresses. But, it's all covered by RFC 6724, and this may help as a
summary:

http://biplane.com.au/blog/?p=22

> do they both use DNS,

As hopefully made clear by the above, it is not the addresses on
your system which "use DNS". It's more like your system uses DNS,
and the DNS may contain both inet and inet6 addresses, thus your
system decides which to communicate with based on which families of
address you have.

> and similar things which might let me make sense of the situation?

Hopefully that helped. It's quite a large topic, so some reading
will be required in many places to fully understand it.

Cheers,
Andy

There are plenty.  Kernels don't get updated in the same way as other
packages.  If you want to track the latest version of the kernel,
install (in your case) linux-image-amd64.  Even then, old kernels aren't
removed on upgrade for safety reasons - in a worst case scenario, it
could leave your system unable to boot.

Those are two different packages, namely firmware-linux-nonfree and
xserver-xorg-video-intel. To get the former you will need to enable the
'non-free' component in your APT sources[1].

You could install lightdm on the server and enable XDMCP. Alternativley
you could consider vnc4server.

Since linux 4.0, the -amd64 kernel flavor is no longer built on i386:

8.6 is Jessie, released April 2015. The Intel H110 chipset was released 
September 2015. One cannot expect satisfactory hardware support from a pure 
Jessie. With Debian, either you need Stretch (or Sid) instead of Jessie, or 
you need to upgrade Kernel and/or Xorg and/or (video) driver to version(s) 
supporting H110.


Do note it's possible you ultimately might not even want to use the Intel 
Xorg video driver. The integrated modesetting driver in Xorg server versions 
1.17.0 and up has been transitioning to preferred video driver status:

If you're firing up X remotely, you don't care what the server's
graphics card can do. 

Install tightvncserver or vnc4server, make sure that you can
tunnel through SSL or SSH, and you should be set.

Setting resolution will be a run-time option.

There's a general misconception here: systemd never creates pid
files for daemons.

The PIDFile= setting in a unit file is a setting that tells
systemd where to look for PID files that it reads in to find
out the main PID of a forking process.

A bit of background: systemd has a concept called "main pid" of
a process. If you use KillMode=process or something along the
lines of ExecReload=/bin/kill -HUP $MAINPID, systemd will
automatically use the main pid of the service for these
operations. Also, a non-main process exiting in a service is
not considered a problem from a systemd perspective, but the
main process exiting is. In a very simple case, the main pid of
a service is trivial: if there's only one pid in a service,
that's the main pid.

However, there are other services that start multiple processes,
and there it's not necessarily easy to determine what the main
process of that service is. In these situations, systemd has
the ability to read pid files (that were written by the service
_itself_ after startup) to determine the main pid. The sequence
would be:

 - systemd starts the program
 - the program forks
 - the fork initializes
 - the program writes the pid file
 - the original process exits
 - systemd notices that, considers the forking service
   initialized, and reads in the pid file

If a forking service doesn't write a pid file, systemd will try
to guess the main process (see the GuessMainPID= setting)
instead. If there's only a single process in the service, that's
going to work reliably, but if there are multiple processes it
might not.

Also, if you don't use Type=forking but other service types,
then PID files are irrelevant from a systemd perspective - and
the PIDFile= setting is ignored. For example, if you have a
Type=notify unit, then the process spawned by systemd will not
exit (startup completion notification is done via the sd-notify
protocol instead) during regular operations, so that's going to
be the main pid of the unit.


Now for your units: I don't have openvpn installed, so I'd have
to check (and am too lazy right now to do so), but for
smartmontools the service is of Type=simple, so nothing forks
there. (smartd is called with -n, with leaves it in the
foreground.) There's simply no need for a PID file here, as the
main pid of the process is trivially known to systemd.

Now if you want to know the main PID of any given running
service for yourself, outside of systemd, then you don't need
a pid file anymore, you can query systemd dynamically,
regardless of service type:

systemctl show -p MainPID smartd.service

for use in scripting you can also do:

PID=$(systemctl show -p MainPID smartd.service 2>/dev/null | cut -d= -f2)
  (will be empty on error, e.g. service not running)

Hope that helps.

Christian

As Michael Biebl said in reply to your mail to debian-systemd:

  This is a bug tracker, not a user support forum.
  Please try the debian-user mailing list for such support questions next
  time.

  If the services in question don't have a pidfile, that's usually an
  indication that they don't use Type=forking, which is perfectly valid.

  Anyway, there is no bug in systemd here. So closing.

There could be a clue in that response for you to investigate. Perhaps
you could do that and report here. Better to provide than just ask for
"any idea". Audit away.

P.S. Your posting seems to live up to your domain name.

Hi all, after upgraded oldstable to stable it happens that systemd 
doesn't create PID file of these packages:


openvpn
smartmontools

and maybe others... I auditing now...

any idea to have PID file of openvpn and smartmontools?

problemas en carpeta compartida en samba

[luis]

Buenas tardes a todos

Tengo problemas para permisos en carpeta compartida en samba en grupo.

Esta es la carpeta compartida y con estos usuarios con usuarios y passwd
también.

[economia]
comment = Carpeta de Contabilidad
path = /home/luis/data/economia
browseable = yes
umask = 000
writeable = yes
readonly = no
valid users = @elisa @susana @marisell @lily
admin user = luis

Todos estos usuarios los tengo agregados al grupo "contabilidad"

Le di estos permisos y nada de nada

# chmod -R 777 /home/luis/data/economia
# chown -R elisa:contabilidad /home/luis/data/economia
# chgrp -R contabilidad /home/luis/data/economia

Elisa es el único usuario que si puede hacer todos los cambios y
modificaciones y el resto de los usuarios del grupo contabilidad es solo
lectura, ver y nada más.

Necesito que todos los usuarios del grupo "contabilidad" entren a la
carpeta compartida y salven y modifiquen cuanto necesiten. de lo contrario
es crear carpeta por usuario y en este caso es conveniente hacerlo así.

Alguna idea de como hacerlo ??

Agradezco toda ayuda

Ok, not quite sure what you are saying here.
You do not want to receive from a specific sender or you want to limit a
local user from sending to non local addresses?

Configuring Postfix

[David FREYCHE]

Hello,

I am new on the list and using a debian distribution 8.0 Jessie with
E-commerce CMS prestashop installed.


Here is the facts:

I receive spam on my mail queue (postqueue)
I already configured postfix with amavis for content filter which works fine



I want to

block sending my from a specific dns



So I want to configure postfix to avoid sending email from address
x...@store.uneaune.com


I configured postfix as follow:

main.cf

  smtp_sender_restrictions - check_sender_access
hash:/etc/postfix/access_dns

access_dns file (with postmap compilation and restarting postfix)

  store.uneaune.com REJECT



It just does not work. I tried something else but no.

Am I doing something wrong?
I have smtpd_relay_restrictions; does it conflicts with sending
restrictions?


Can you provide me some assistance?

David FREYCHE

Re: Duvida OpenVpn

[Thiago T. Faioli]

Boa tarde Marcelo


O projeto FreeRADIUS já disponibiliza as DDL's pra criação das tabelas no
banco de dados MySQL. Em algum lugar da estrutura de diretório está esse
arquivo db_mysql.sql que contem todos os arquivos pra configuração do banco
mysql...

Portanto utilize esse cara pra te ajudar nas criações das tabelas
necessárias ...

Crie o banco do radiu

# mysqladmin -psenha create nomebanco

E crie as tabelas com o comando:

# mysql -psenha radius < db_mysql.sql


No  arquivo radiusd.conf  configure-o para autenticar os dados no MySQL.
Modifique as seções "authorize" e "accounting" insira "sql"

dessa forma:

authorise {
sql
}



accounting {
sql
}

Isso fará com que os usuários sejam procurados na tabela radcheck e fará
com que os dados das conexões sejam armazenadas na tabela radacct do banco
de dados que criou para o radius no MySQL


Depois edite o sql.conf e descomente as linhas:

simul_count_query
simul_verify_query

Agora é criar o usuario no DB

# mysql -psenha bancoradius

Criar usuário:

INSERT INTO radcheck (username, attribute, op, value)  VALUES (''usuario',
'Password', '==', 'senha');

Criar grupo com direito a uma conexão chamado 'sessaounic':

INSERT INTO radgroupcheck (groupname, attribute, op, value) VALUES
('sessaounic', 'Simultaneous-Use', ':=', 1);

Inserir 'usuario' no grupo:

mysql> INSERT INTO usergroup (username, groupname) VALUES ('usuario',
'sessaounic');



Cara... é bem por aí...

With Jessie 8.6, gdm3 and XDMCP, the GDM face browser is built but not displayed

[Jean-Paul Bouchet]

Hello,

We used during 2 years Gnome and gdm3 on a server with Debian Wheezy to 
let users open sessions from their Windows PC via Cygwin and xlaunch 
(xdmcp). It worked well till the upgrade to Jessie 8.5, for these 
Windows PC, as for the system console. The upgrade to Jessie 8.6 didn't 
solve the problem.


I have already tried to describe these problems the 09th of september 
("gdm3 doesn't work any more after the upgrade from Wheezy to Jessie 
8.5") :


https://lists.debian.org/debian-user/2016/09/msg00301.html

As users were satisfied by the environment provided with gnome, when the 
server ran on Wheezy, I am still trying to launch gdm3.


The story is the same for the console (when the system restarts) and for 
the Windows PC (at each launching of xlaunch): I get during a split 
second a gray background screen, probably corresponding to the GDM face 
browser, followed during a new split second by a nice blue screen 
(debian 8 on the bottom-left corner, date and time on the middle, and a 
few icons on the upper left which are able to display information about 
the connection to the network), followed by a dark screen, till the 
first mouse or keyboard event, that activates definitely the blue 
screen. For the console the dark screen is very ephemeral and appears 
only once before the blue screen is displayed.


I have tried to follow what happens really and read carefully the 
/var/log files. It is clear that the GDM face browser with the list of 
all users is being built, but I have not understood why it is not 
displayed : warning and errors traced in these files should be more 
understandable for a person more expert than me in Gnome and gdm3. I 
have prepared a file with extracts from /var/log/system and 
/var/log/debug, compressed with bzip2 ...


I have read the warning about the upgrading from wheezie to jessie:
5.10. The GNOME desktop requires basic 3D graphics
The GNOME 3.14 desktop in Jessie no longer has fallback support for 
machines without basic 3D graphics. To run properly, it needs either a 
recent enough PC (any PC built in the last 10 years should have the 
required SSE2 support) or, for architectures other than i386 and amd64, 
a 3D-accelerated graphics adapter with EGL drivers.


It could mean that was I am trying to do is no more possible. But during 
the 3 first days just after the upgrading I had a degraded but nearly 
working situation with Windows PC: a few minutes to get the GDM face 
bowser, again a few minutes to get the session, which was then normal 
but impossible to close, and sometimes nothing. My attempts to improve 
the situation lead to a much clearer one: what I get now is always this 
nice blue screen, maybe built by gnome-screensaver (I am not sure at 
all). That was not exactly my aim... But it lets me think or hope that I 
am not in the case reported in the warning 5.10.


Today I don't ever know whether the problem I try to solve may be solved 
or not, and if it is due to an error of installation (lacking packages 
to install or packages to uninstall), or an error of configuration or, 
possibly, a bug of Jessie.


It would be nice if someone could answer that it works on his system : 
Jessie, gdm3 with xdmcp enabled and Windows PC emulating a X11 server 
with xlaunch (through Cygwin or another free software) to open sessions.


Many thanks in advance !

Best regards,

Jean-Paul
