Here is my hosts file:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
192.168.1.27 mail.im3g.com mail
::1 localhost6.localdomain6 localhost6
and when i run "nslookup mail.im3g.com", it return
Server: 192.168.1.27
Address: 192.168.1.27#53
Name: mail.im3g.com
Address: 192.168.1.27
when I run "hostname" and "hostname -f", it both return "mail.im3g.com"
I disabled firewall and SElinux, but I also did the tutorial in
howtoforge. It is based on
Split DNS
Could you please tell me where the potential fault is?
