How to enable port 25 on my Ubuntu server?
So I am running Spree e-commerce in Rails. When I click on 'place order' after I have added items to my cart and proceed to checkout i got this error. (same question as this person)
Errno::ECONNREFUSED in Spree::CheckoutController#update Connection refused - connect(2) for "localhost" port 25
I believe it has something to do with the email but I am not 100 percent sure. As for spree is defaulted to port 25 as referred to here
I checked my port using
telnet mydroplet'sIPaddress 25
and it said (as expected)
telnet: Unable to connect to remote host: Connection refused
I tried a solution to unblock my port 25 by adding the line below as suggested in another question here.
iptables -I INPUT -p tcp -m tcp --dport 25 -j ACCEPT
and recheck using the same method and still no good.
I even went to setup my firewall using ufw and made sure my port 25 is available by following this tutorial
sudo ufw allow 25/tcp
still no good...
How do I enable my port 25?
I am running Ubuntu Ruby on Rails on 14.04 (Postgres, Nginx, Unicorn).
My IP address is 126.96.36.199 if anyone wants to try my port 25.
