[Solved] Name or service not known

[chromatic6]

Hi,
I have the message "Name or service not known" when I try to fetch the overlays list with layman, and a lot of internet apps doesn't work anymore like svn, liferea, pidgin, wget... I can't resolve any hostname in this apps. But I browse in firefox without any problem.
I've tried to search the forums and spent a lot of time on this but I don't find any solution.

sounds like a dns issue... what are the contents of your /etc/resolv.conf file?

My resolv.conf seems good as it is generated by dhcpcd

Code: Select all

# Generated by dhcpcd for interface wlan0
nameserver 192.168.1.1
nameserver 0.0.0.0

/etc/hosts

Code: Select all

127.0.0.1       localhost

/etc/conf.d/hostname

Code: Select all

HOSTNAME="localhost"

/etc/conf.d/wireless

Code: Select all

modules=( "ifconfig" )

config_wlan0=( "dhcp" )
essid_wlan0=( "MyEssid" )
key_MyEssid="MyKey"

some lines in /etc/conf.d/rc

Code: Select all

RC_PLUG_SERVICES=""
RC_NET_STRICT_CHECKING="lo"
RC_DOWN_INTERFACE="yes"

/etc/hosts.conf

Code: Select all

# The  file /etc/host.conf contains configuration information specific to
# the resolver library.  It should contain one configuration keyword  per
# line,  followed by appropriate configuration information.  The keywords
# recognized are order, trim, mdns, multi, nospoof, spoof, and reorder.



# This keyword specifies how host lookups are to be performed. It
# should be followed by one or more lookup methods, separated by
# commas.  Valid methods are bind, hosts, and nis.
#
order hosts, bind


# Valid  values are on and off.  If set to on, the resolv+ library
# will return all valid addresses for a host that appears  in  the
# /etc/hosts  file,  instead  of  only  the first.  This is off by
# default, as it may cause a substantial performance loss at sites
# with large hosts files.
#
multi off

I finally found the problem !!
There was a line in /etc/nsswitch.conf with strange entries like mdns4, [ERROR ...]. I don't really remember.

I replaced it by:

Code: Select all

hosts:		files dns

And now everything works
