Problem z DNS
« dnia: Marzec 22, 2015, 10:50:12 pm »
Witam

Minęło trochę czasu odkąd przesiadłem się na SUSE 13.1 i do tej pory działał bez problemu. Ostatnio jednak zaczął mieć kłopoty z rozwiązywaniem nazw w sieci LAN.

W pierwszym momencie wyświetliłem oczywiście zawartość /etc/resvolv.conf. Poza instrukcjami o nieedytowaniu i network config istnieją tylko dwie niehaszowane linijki:

nameserver 8.8.8.8
nameserver 10.1.XXX.1

Serwer Googla to oczywisty śmieć!

sprawdziłem też plik /etc/sysconfig/network/config próbowałem ustawień

NETCONFIG_DNS_POLICY='auto' i NETCONFIG_DNS_POLICY='*'

Nic jednak z tego nie wynika. Wciąż namolnie wraca do mnie nameserver 8.8.8.8

POMOCY!

Może dostajesz taki adres przez DHCP? Niestety nic więcej o konfiguracji sieci nie podałeś, więc nic więcej nie pomożemy.

Nie mogę wysłać ustawień serwera DHCP - tajemnica firmowa ale zapewniam, że jedyny DNS który przychodzi to 10.1.XXX.1 - zresztą jak w AD to bywa jest to także adres serwera DHCP

Myślę, że temat jest do zamknięcia...

Po restarcie maszyny (update systemu) nie działa mi też środowisko graficzne i usługa DHCP - myślę, że problem leży zupełnie gdzindziej

Problem wrócił ponownie.

Otóż dziś na mieście podpiąłem modem Huwawei.  Ponieważ suse jest 13.2 musiałem użyć polecenia USB_modeswitch

Następnie za pomocą anyconecta utworzyłem tunel do firmy (testowane wielokrotnie) i stało się /etc/resvolv.conf nie zmienia - w ogóle.

Ustawienia DHCP
 

Ustawinie resvolv uryłem domenę
cat /etc/resolv.conf
### /etc/resolv.conf file autogenerated by netconfig!
#
# Before you change this file manually, consider to define the
# static DNS configuration using the following variables in the
# /etc/sysconfig/network/config file:
#     NETCONFIG_DNS_STATIC_SEARCHLIST
#     NETCONFIG_DNS_STATIC_SERVERS
#     NETCONFIG_DNS_FORWARDER
# or disable DNS configuration updates via netconfig by setting:
#     NETCONFIG_DNS_POLICY=''
#
# See also the netconfig(8) manual page and other documentation.
#
# Note: Manual change of this file disables netconfig too, but
# may get lost when this file contains comments or empty lines
# only, the netconfig settings are same with settings in this
# file and in case of a "netconfig update -f" call.
#
### Please remove (at least) this line when you modify the file!

## Path: Network/General
## Description: Global network configuration
#
# Note:
# Most of the options can and should be overridden by per-interface

# of these options -- NetworkManager is not using any sysconfig settings.

## Type:        yesno
## Default:     yes
# If ifup should check if an IPv4 address is already in use, set this to yes.
#
# Make sure that packet sockets (CONFIG_PACKET) are supported in the kernel,

# Also be aware that this takes one second per interface; consider that when
# setting up a lot of interfaces.
CHECK_DUPLICATE_IP="yes"

## Type:        list(auto,yes,no)
## Default:     auto
# If ifup should send a gratuitous ARP to inform the receivers about its
# IPv4 addresses. Default is to send gratuitous ARP, when duplicate IPv4

# When using NetworkManager you may define a timeout to wait for NetworkManager

## Type:        string
## Default:     "dns-resolver dns-bind ntp-runtime nis"

## Type: yesno
## Default: no

# This variable enables netconfig to always force a replace of modified

#
# The purpose is to use it as workaround, when some other tool trashes
# the files, e.g. /etc/resolv.conf and you observe messages like this
# in your logs on in "netconfig update" output:
# ATTENTION: You have modified /etc/resolv.conf. Leaving it untouched.
