Après dnsmasq

cat /etc/dnsmasq.conf

# Configuration file for dnsmasq.
#
# Format is one option per line, legal options are the same
# as the long options legal on the command line. See
# "/usr/sbin/dnsmasq --help" or "man 8 dnsmasq" for details.

# Listen on this specific port instead of the standard DNS port
# (53). Setting this to zero completely disables DNS function,
# leaving only DHCP and/or TFTP.
#port=5353

# The following two options make you a better netizen, since they
# tell dnsmasq to filter out queries which the public DNS cannot
# answer, and which load the servers (especially the root servers)
# unnecessarily. If you have a dial-on-demand link they also stop
# these requests from bringing up the link unnecessarily.

# Never forward plain names (without a dot or domain part)
#domain-needed
# Never forward addresses in the non-routed address spaces.
#bogus-priv

# Uncomment these to enable DNSSEC validation and caching:
# (Requires dnsmasq to be built with DNSSEC option.)
#conf-file=%%PREFIX%%/share/dnsmasq/trust-anchors.conf
#dnssec

# Replies which are not DNSSEC signed may be legitimate, because the domain
# is unsigned, or may be forgeries. Setting this option tells dnsmasq to
# check that an unsigned reply is OK, by finding a secure proof that a DS 
# record somewhere between the root and the domain does not exist. 
# The cost of setting this is that even queries in unsigned domains will need
# one or more extra DNS queries to verify.
#dnssec-check-unsigned

# Uncomment this to filter useless windows-originated DNS requests
# which can trigger dial-on-demand links needlessly.
# Note that (amongst other things) this blocks all SRV requests,
# so don't use it if you use eg Kerberos, SIP, XMMP or Google-talk.
# This option only affects forwarding, SRV records originating for
# dnsmasq (via srv-host= lines) are not suppressed by it.
#filterwin2k

# Change this line if you want dns to get its upstream servers from
# somewhere other that /etc/resolv.conf
#resolv-file=

# By  default,  dnsmasq  will  send queries to any of the upstream
# servers it knows about and tries to favour servers to are  known
# to  be  up.  Uncommenting this forces dnsmasq to try each query
# with  each  server  strictly  in  the  order  they   appear   in
# /etc/resolv.conf
#strict-order

# If you don't want dnsmasq to read /etc/resolv.conf or any other
# file, getting its servers from this file instead (see below), then
# uncomment this.
#no-resolv

# If you don't want dnsmasq to poll /etc/resolv.conf or other resolv
# files for changes and re-read them then uncomment this.
#no-poll

# Add other name servers here, with domain specs if they are for
# non-public domains.
#server=/localnet/192.168.0.1

# Example of routing PTR queries to nameservers: this will send all
# address->name queries for 192.168.3/24 to nameserver 10.1.2.3
#server=/3.168.192.in-addr.arpa/10.1.2.3

# Add local-only domains here, queries in these domains are answered
# from /etc/hosts or DHCP only.
#local=/localnet/

# Add domains which you want to force to an IP address here.
# The example below send any host in double-click.net to a local
# web-server.
#address=/double-click.net/127.0.0.1

# --address (and --server) work with IPv6 addresses too.
#address=/www.thekelleys.org.uk/fe80::20d:60ff:fe36:f83

# Add the IPs of all queries to yahoo.com, google.com, and their
# subdomains to the vpn and search ipsets:
#ipset=/yahoo.com/google.com/vpn,search

# You can control how dnsmasq talks to a server: this forces
# queries to 10.1.2.3 to be routed via eth1
# server=10.1.2.3@eth1

# and this sets the source (ie local) address used to talk to
# 10.1.2.3 to 192.168.1.1 port 55 (there must be a interface with that
# IP on the machine, obviously).
# server=10.1.2.3@192.168.1.1#55

# If you want dnsmasq to change uid and gid to something other
# than the default, edit the following lines.
#user=
#group=

# If you want dnsmasq to listen for DHCP and DNS requests only on
# specified interfaces (and the loopback) give the name of the
# interface (eg eth0) here.
# Repeat the line for more than one interface.
#interface=
# Or you can specify which interface _not_ to listen on
#except-interface=
# Or which to listen on by address (remember to include 127.0.0.1 if
# you use this.)
#listen-address=
# If you want dnsmasq to provide only DNS service on an interface,
# configure it as shown above, and then use the following line to
# disable DHCP and TFTP on it.
#no-dhcp-interface=

# On systems which support it, dnsmasq binds the wildcard address,
# even when it is listening on only some interfaces. It then discards
# requests that it shouldn't reply to. This has the advantage of
# working even when interfaces come and go and change address. If you
# want dnsmasq to really bind only the interfaces it is listening on,
# uncomment this option. About the only time you may need this is when
# running another nameserver on the same machine.
#bind-interfaces

# If you don't want dnsmasq to read /etc/hosts, uncomment the
# following line.
#no-hosts
# or if you want it to read another file, as well as /etc/hosts, use
# this.
#addn-hosts=/etc/banner_add_hosts

# Set this (and domain: see below) if you want to have a domain
# automatically added to simple names in a hosts-file.
#expand-hosts

# Set the domain for dnsmasq. this is optional, but if it is set, it
# does the following things.
# 1) Allows DHCP hosts to have fully qualified domain names, as long
#     as the domain part matches this setting.
# 2) Sets the "domain" DHCP option thereby potentially setting the
#    domain of all systems configured by DHCP
# 3) Provides the domain part for "expand-hosts"
#domain=thekelleys.org.uk

# Set a different domain for a particular subnet
#domain=wireless.thekelleys.org.uk,192.168.2.0/24

# Same idea, but range rather then subnet
#domain=reserved.thekelleys.org.uk,192.68.3.100,192.168.3.200

# Uncomment this to enable the integrated DHCP server, you need
# to supply the range of addresses available for lease and optionally
# a lease time. If you have more than one network, you will need to
# repeat this for each network on which you want to supply DHCP
# service.
#dhcp-range=192.168.0.50,192.168.0.150,12h

# This is an example of a DHCP range where the netmask is given. This
# is needed for networks we reach the dnsmasq DHCP server via a relay
# agent. If you don't know what a DHCP relay agent is, you probably
# don't need to worry about this.
#dhcp-range=192.168.0.50,192.168.0.150,255.255.255.0,12h

# This is an example of a DHCP range which sets a tag, so that
# some DHCP options may be set only for this network.

# Set the DHCP server to authoritative mode. In this mode it will barge in
# and take over the lease for any client which broadcasts on the network,
# whether it has a record of the lease or not. This avoids long timeouts
# when a machine wakes up on a new network. DO NOT enable this if there's
# the slightest chance that you might end up accidentally configuring a DHCP
# server for your campus/company accidentally. The ISC server uses
# the same option, and this URL provides more information:

# If you want to disable negative caching, uncomment this.
#no-negcache

# Normally responses which come from /etc/hosts and the DHCP lease
# file have Time-To-Live set as zero, which conventionally means
# do not cache further. If you are happy to trade lower load on the
# server for potentially stale date, you can set a time-to-live (in
# seconds) here.
#local-ttl=

# If you want dnsmasq to detect attempts by Verisign to send queries
# to unregistered .com and .net hosts to its sitefinder service and
# have dnsmasq instead return the correct NXDOMAIN response, uncomment
# this line. You can add similar lines to do the same for other
# registries which have implemented wildcard A records.
#bogus-nxdomain=64.94.110.11

# If you want to fix up DNS results from upstream servers, use the
# alias option. This only works for IPv4.
# This alias makes a result of 1.2.3.4 appear as 5.6.7.8
#alias=1.2.3.4,5.6.7.8
# and this maps 1.2.3.x to 5.6.7.x
#alias=1.2.3.0,5.6.7.0,255.255.255.0

# See RFC 2782.
# You may add multiple srv-host lines.

Bonjour Owl-Express

Dans un de tes précédents messages,
je me suis permis de modifier le retour de la commande

sudo gdebi ctparental_ubuntu_16.04_4.20.7-1.0_all.deb

Merci, à ce moment là je ne maîtrisais pas encore la mise en forme :slight_smile:

Moi aussi, il m’a fallu un certain temps pour m’adapter à ces balises que je ne connaissais pas .:slight_smile:

commente ou supprime les lignes suivantes dans /etc/sysctl.conf

net.ipv6.conf.all.disable_ipv6=1
net.ipv6.conf.default.disable_ipv6=1
net.ipv6.conf.lo.disable_ipv6=1

valide le changement par sudo sysctl -p /etc/sysctl.conf

et on vas aussi désinstaller resolvconf car peut être que cela vient de la.

sudo apt-get autoremove --purge resolvconf dnsmasq

vérifie que tu est bien internet puis install dnsmasq

sudo apt-get install dnsmasq

revérifie que tu est encore internet si sa fonctionne passe a l’install de ctparental.

bonsoir,
Hélas !
A la désinstallation de resolvconf je perd le ping, même après un reboot. Plus d’internet du tout, sueur froide, je tente une réinstallation de resolvconf, OK, j’ai retrouvé mon réseau avec DNS.
A la réinstallation de dnsmasq, je perd le ping …
je redémarre alors l’ordinateur, j’ai un ping.

Donc j’essaie d’installer ctparental, mais là plantage, plus de ping…
Alors je reboote, ping fonctionne, je tente une réinstallation …
Plus rien …
Retour à la case départ …
Désolé, le sort s’acharne contre moi … ça pourrait être dû au fait que je tourne en 64 bits ?

le 64bit n’y change rien je suis aussi en 64bit, est sa fonctionne, par contre la distribution ou l’ajout de dépôt non standard peut influer .
retourne la distribution utilisé et le retour de ces commandes , je vais voir si j’arrive a reproduire le prolême en virtualbox .

cat /etc/apt/sources.list /etc/apt/sources.list.d/*
et
cat /etc/apt/preferences cat /etc/apt/preferences.d/*

heee, je remarque que tu a beaucoup de dépôts , type ppa qui sont même pour différente version d’ubuntu, sa rend le système extrêmement instable, le principe est le même que décrit ici https://www.debian-fr.xyz/viewtopic.php?f=7&t=584 , tu utilise une version stable d’ubuntu si tu veut qu’elle reste n’ajoute pas trop de dépôt ppa et autres et si tu le fait seulement ceux prévus pour tas version d’ubuntu (16.04=xenial), est pour faire bien, associes y un fichier preferences , l’exemple ci dessous priorise les dépôts officiels pour ubuntu 16.04
aux depots ppa et freepascal . explication détailler ici

/etc/apt/preferences.d/xenial

Package: *
Pin: release v=16.04,o=Ubuntu
Pin-Priority: 900

Package: *
Pin: origin ppa.launchpad.net

si tu veux les dernier paquets , soit passe a ubuntu 16.10 , ou encore mieux debian sid/testing , dans l’exemple si dessous sid et priorisé sur testing.

/etc/apt/preferences.d/testing-sid

C’est curieux quand même, de mémoire /etc/apt/sources.list n’est plus pris en compte par le système de no jours, non ?
Quand je regarde le paramétrage de mes dépôts sur l’interface graphique, je suis plutôt “propre” par rapport à une certaine époque …

j’ai fait un peu de ménage dans l’onglet “autres logiciels” et j’ai enlevés les dépôts “code source” qui n’avaient pas migré lors des mises à jours de version Ubuntu.

je me retrouve avec ça :
cat /etc/apt/sources.list /etc/apt/sources.list.d/*

Il restait un paquet de fichiers en *.distUpgrade que j’ai déplacé ailleurs, avant de les effacer.

j’ai aussi ajouté le /etc/apt/preferences.d/xenial que tu m’as proposé.
Je migrerais en 16.10 dès que possible (sans doutes la semaine prochaine) pour rester homogène avec mon PC portable.

Bref j’ai assaini mon installation
Mais je n’arrive toujours pas à installer …

C’est curieux quand même, de mémoire /etc/apt/sources.list n’est plus pris en compte par le système de no jours, non ?

je c’est pas ou tu a pu lire sa mais c’est faut .
les interfaces graphiques ne font normalement qu’éditer ce/ces fichier/s en évitent les erreur de syntaxe,
mais elle on toutes pour base apt-get .

malheureusement une foie que le system deviens instable il ne suffit pas de modifier la sources de mise a jour pour résoudre les problèmes , car de nombreuse librairie peuvent-avoir étais installer avec des versions non compatible avec toutes les applications, bref c’est complexe est c’est pour cela qu’il faut faire attentions avec les dépôts que l’on ajoute, mais bon on a toussent fait sa au moins une foie :slight_smile: .

un conseille pour ta migration fait une install a partir d’un cd est pas juste un upgrade , tu seras sur d’avoir un system conforme. si ta partition home est séparer tu ne perdras pas de donnée en t’y prennent bien.

Bon, après une réinstallation complète de mon système tout est OK, mais je déteste devoir tout réinstaller …
En tous cas merci pour le support :slight_smile:

Notes sur l’utlisatien de CTparental avec GnomeShell

Bonjour,

Une petite note pour ceux qui veulent utiliser CTparental avec Gnome shell :

Le proxy transparent semble ne pas fonctionner avec les application Gnome (epiphany, applet météo, gnome-maps, etc…) pour résoudre le problème il faux explicitement déclarer l’utilisation de localhost comme serveur mandataire dans les paramètres réseau pour le http et le https. Pour que cela fonctionne totalement il ne faut pas oublier de retirer de la ligne Ignorer les hôtes localhost et 127.0.0.1.
