playframework - Amazon EC2 instance - Play Framework connectivity -


i created ec2 instance , added tcp , udp ports. icmp also... started play application both port 9000 , 80, neither worked out. application starts, can connect instance cannot connect outside.

telnet instance_dns_name 9000 fails whereas telnet instance_dns_name 3389 works.

i don't know missing. same issue happened in microsoft's azure too. may region?

one more important thing...

if have amazon ec2 instance of debian or ubuntu - default, not have internal firewall (iptables)

on other hand, redhat enterprise edition do have firewall , if want work properly, can open proper ports in iptables or disable iptables - choice.

i prefer disable iptables since have amazon security groups same role iptables.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
