problem with gethostbyname/1

[david wallin]

Sean,

This is on my Linux box (before):

Eshell V5.3  (abort with ^G)
1> inet_db:res_option(lookup).
[]

I added '{lookup, ["file","dns"]}.' to the '.inetrc' file, and now 
gethostbyname/1 works like a charm. Even net_adm:ping/1 works, which is 
nice :-)

thanks a million,

--david.
