ruby - Connection refused when using imap.rb to connect to imap.google.com -


i'm trying connect gmail account (via ruby-gmail gem, gmail gem, gmail_xoauth gem on oauth 2.0, each method uses imap.rb) , getting:

c:/ruby21-x64/lib/ruby/2.1.0/net/imap.rb:1045:in `initialize': no connection made because target machine actively refused it. - connect(2) "imap.gmail.com" port 993 (errno::econnrefused)

on gmail account have:

  1. ensured can accessed through web login
  2. ensured it's activated
  3. enabled imap
  4. allowed access insecure apps

in connection have:

  1. ensured made on ssl
  2. ensured uses correct login details , tokens applicable
  3. tried ports 993 , 465

what else try? how rule out firewall being issue, without having control on it?

.. (errno::econnrefused)

... how rule out firewall being issue, without having control on it?

it firewall. error message says connection service got actively refused. since working me doubt google refusing service must firewall in between.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
