Sudo error ubuntu server

Question

Hello I am using ubuntu server and I am getting an error when I try to use sudo:

sudo: unable to resolve host ira: Resource temporarily unavailable

I have looked this error up and people say its something with /etc/hosts/

Here is mine:

127.0.0.1       localhost.localdomain   localhost
::1             localhost6.localdomain6 localhost6

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

What is wrong with this file? Also what could cause this? was it someone changing this file by hand or is it the system that did it?

Thanks, Ira.

Try to add in your /etc/hosts something like

 127.0.1.1    your-machine
