Hi,
I am developing a C program to upload file to an FTP Server in Debian
Linux(Beaglebone black). The system provides options to setup the
ethernet interface statically or via dhcp. I am able to upload my file
when my eth interface is setup using dhcp. The /etc/resolv.conf file
gets updated with my local network's DNS nameservers in this case. But,
when static ethernet configuration is used, after setting the IP
Address, Netmask and gateway, I am overwriting the /etc/resolv.conf file
with google public DNS server address (8.8.8.8) using the command
echo nameserver 8.8.8.8 > /etc/resolv.conf
The file is getting updated and the operation exits with error "Timeout
was reached".
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.
I tried using OpenDNS namserver insted of google's DNS but there is no
luck.
If I replace the nameserver 8.8.8.8 with the local DNS IP address that I
received during dhcp operation, as follows:
echo nameserver "local dns server ip" > /etc/resolv.conf,
I am able to complete the FTP operation.
Request help to understand the cause of the issue. Thanks in advance.
Regards
Ison Thomas
