Answer 1

I'm using openSUSE 13.1 OS for my rails development. Suddenly I got the same issue and reported to the SUSE mailing list. And then got an very good explanation about the problem here.

Background: the tld ".site" is offically registered and thus no longer available for private use.

ToDo: Change your private tld, to something NOT registered.

Gotchas: ".local" is reserved for mDNS / ZeroConf / Bonjour / Rendezvous. Do NOT use it for DNS / DHCP !

Examples: ".box", ".lan" : both are suggested by some Internet-Connect-Routers (DSL/Cable/Fibre) ".lnet", ".your-name-here" (.ArupRakshit for you) : possible, worth to try.

HTH, Yamaban.

I followed his instrutions here

For future reader goto YAST -> Netwrok devices -> Network Settings -> Hostname/DNS -> Domain Name (and here put your name).

[arup@Rails]$ gem install rails --no-ri --no-rdoc
Fetching: thread_safe-0.3.5.gem (100%)
Successfully installed thread_safe-0.3.5

Fetching: i18n-0.7.0.gem (100%)

[arup@Rails]$ rails -v
Rails 4.2.0

Now all is set. :)
