Curl and download error of packages

Most of the time i am behind a NAT router either at work or at home and those error are pretty common on my openSUSE system.

The old school trick i always do is ping those hosts.

 ping download.opensuse.org 

 ping downloadcontent.opensuse.org 

now edit the file /etc/hosts  and add

 RESULT-OF-IP-FROM-PING  download.opensuse.org 

 RESULT-OF-IP-FROM-PING  downloadcontent.opensuse.org 

eg. something like this.

 195.135.221.134  download.opensuse.org 
 195.135.221.157  downloadcontent.opensuse.org  

That trick always saves me from choosing a local mirror manually. It works for me and I'm not saying it will work for everyone, just try it and see.
