/Hi,
/

/> echo nameserver 8.8.8.8 > /etc/resolv.conf /
/> /
/> The file is getting updated and the operation exits with error
"Timeout was /
/> reached". /

Sorry, but is that the error message from curl when it fails?

/Yes that is the error message from curl when it fails. /

/> I am able to "ping www.google.com" and "ping my_ftp_server" with
8.8.8.8 as /
/> the only entry in the resolv.conf file, but the curl operation fails. /

Which libcurl version? On Linux? What name resolver backend does your
libcurl
use? 'curl -V' shows.

/Sorry, I missed out the libcurl version in my querry. It is 7.45. I am
using debian jessie in Beaglebone Black.
I have cross compiled curl and is using the library from my application.
I have compiled the library with "--enable-threaded_resolver". curl -V
gives the following output:/

curl 7.48.0 (armv7l-unknown-linux-gnueabihf) libcurl/7.38.0
OpenSSL/1.0.1k zlib/1.2.8 libidn/1.29 libssh2/1.4.3 librtmp/2.3
Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps
pop3 pop3s rtmp rtsp scp sftp smtp smtps telnet tftp
Features: AsynchDNS IDN IPv6 Largefile GSS-API SPNEGO NTLM NTLM_WB SSL
libz TLS-SRP

Can you please be more specific about the exact error message and return
code
you get from libcurl?

/The error code is 28 and the error message is /Timeout was //reached//

As Dan Fandrich already asked you on curl-users: Can you use the Google DNS
server manually? e.g. does "host www.google.com 8.8.8.8" or "dig
www.google.com @8.8.8.8" return anything?

The following is the output for host www.google.com 8.8.8.8

/root_at_arm:/home/debian# echo nameserver 8.8.8.8 > /etc/resolv.conf
root_at_arm:/home/debian# cat /etc/resolv.conf
nameserver 8.8.8.8
root_at_arm:/home/debian# host //www.google.com//8.8.8.8
Using domain server:
Name: 8.8.8.8
Address: 8.8.8.8#53
Aliases:

//www.google.com//has address 216.58.197.68 //
www.google.com//has IPv6 address 2404:6800:4007:806::2004/
