[Swift-user] problem with running coaster

Fri Sep 19 20:48:48 CDT 2014

Hi all

I have a problem in running swift over the cloud of Microsoft Azure. I have
two nodes on the cloud. I installed swift on one of them and I can run
part01-03 locally successfully. I am trying to use the coaster to run
part04-part-6 on the other node. Here is the output I get for "swift
p4.swift"

I had this problem before with my laptop connecting to a remote server and Yadu
Nand Babuji  told me it is because I don't have  a public ip.
But, I have the problem again now with my nodes in the cloud having the
public ip.
Though as  can be seen in the log, during the connection coaster uses the
private ip
(100.74.60.3)

Is this really a problem with public IP?
Does anybody know how to solve this problem ?
