DNS settings in FreeBSD?

[Xu Qiang]

Hi, all: 

Last time I asked you that why the machine can map the hostname to ip address without setting DNS Server in "/etc/rc.conf". 

Now I remember that I have provided DNS ip address in the initial installing stage, where the installation wizard asked for me about the settings step by step, in which I set the machine's hostname, ip address, domain, gateway, subnet mask, and DNS server ip address. 

Now, when I open the file "/etc/rc.conf", I found the machine's hostname, ip address, subnet mask, domain, and gateway/router are all in it. 

Yet, where is the DNS setting? If not in this file, which file does this setting reside in?

P.S.: In solaris, I can use dos2unix to transfer txt file from DOS/Windows format to Unix format, what is the corresponding command in FreeBSD?


Thanks,
