    I have the following problem.

    I am using my RaspBerry (with RaspBian installed) by SSH.

    My problem is that I can't use wget command because it fails.

    For example if I try to execute the following command:

    sudo wget http://dietrofuoritempo.files.wordpress.com/2013/02/bla-bla.jpg

    I obtain this error message:

    --2014-05-29 19:39:11--  http://dietrofuoritempo.files.wordpress.com/2013/02/bla-bla.jpg
Resolving dietrofuoritempo.files.wordpress.com (dietrofuoritempo.files.wordpress.com)... failed: No address associated with hostname.
wget: unable to resolve host address `dietrofuoritempo.files.wordpress.com'
pi@raspberrypi ~/driverWireless $ sudo wget http://dietrofuoritempo.files.wordpress.com/2013/02/bla-bla.jpg

    The strange thing is that I can ping it:

    pi@raspberrypi ~/driverWireless $ ping dietrofuoritempo.files.wordpress.com
PING dietrofuoritempo.files.wordpress.com (192.0.80.175) 56(84) bytes of data.
64 bytes from dietrofuoritempo.files.wordpress.com (192.0.80.175): icmp_req=1 ttl=41 time=164 ms
64 bytes from dietrofuoritempo.files.wordpress.com (192.0.80.175): icmp_req=2 ttl=41 time=167 ms

    Why? What can I do to solve this issue?

    (on my Ubuntu Linux system I have no problem to perform wget command)

    It could be your version of wget on the pi. Try forcing IPv4, rather letting it try to use IPv6:

    sudo wget -4 http://dietrofuoritempo.files.wordpress.com/2013/02/bla-bla.jpg

    The -4 will restrict it to IPv4.

    But when I try to wget any other site it working! Very strange thing is when I type:

    command in my firefox web browser the file is reachable and download is strated. So, my port is open. Am I right? What can be the problem? Here is my config from networking :

    debian:~# cat /etc/networking/interfaces
cat: /etc/networking/interfaces: No such file or directory
debian:~# cat /etc/network/interfaces
### The loopback network interface
auto lo
iface lo inet loopback

###The primary network interface
allow-hotplug eth1
auto eth1
iface eth1 inet static
address 192.168.50.111
netmask 255.255.255.0
broadcast 192.168.50.255
gateway 192.168.50.99
debian:~#

    The archive.tar file is putted to /vat/www/archive.tar Local port 80 is forwared in my router to external port 1082 My no.ip dns address is vaild and reachable through firefox. Have someone any suggestion what coud be a problem? Thx.

    The issue might be that your routing tables, or your ASDL router's, are being too clever, and a LAN-connection attempt to the external address is being re-written or routed to the machine internally. That is, your packets are not visiting the WAN.

    That is an issue, because you are only listening on :1082 on your WAN, not your LAN.

    Try adjusting your apache so that it listens on 1082. If the connection is being routed internal to the LAN, the connection is arriving to your server on port 1082.
