I'm wondering that the resolution is't functioning when i put a pair of IP-address/name in the file /etc/hosts I'm using SuSE 9.0 or SuSE 8.1 and have the same problem/error. The configuration files seems correct: /etc/nsswitch.conf= hosts: files dns /etc/host.conf= order hosts, bind /etc/hosts= 10.100.0.1 hello /etc/sysconfig/suseconfig= CHECK_ETC_HOSTS="yes" BEAUTIFY_ETC_HOSTS="yes" and the used command is = $ host hello. Host hello not found: 3(NXDOMAIN) ============================================== To check all the thinks ones type this : $ host hello.; egrep "^hosts|^order|hello" /etc/nsswitch.conf /etc/host.conf ; grep -H "HOSTS" /etc/sysconfig/suseconfig |grep -v "^[^:]*:#"/etc/hosts Host hello not found: 3(NXDOMAIN) /etc/nsswitch.conf:hosts: files dns /etc/host.conf:order hosts, bind /etc/hosts:10.100.0.1 hello /etc/sysconfig/suseconfig:CHECK_ETC_HOSTS="yes" /etc/sysconfig/suseconfig:BEAUTIFY_ETC_HOSTS="yes" What should i do to have it functioning ? Thanks in advance.
