I tried to use the command
hg clone ssh://<USERNAME_AT_SOUCEFORGE>@hg.code.sf.net/p/jikesrvm/code  to get the code and apply fix for the RVM-1017 which I did it in repository cloned using http. But I am getting  error below

running ssh pushparaj89@hg.code.sf.net "hg -R p/jikesrvm/code serve --stdio"
remote: ssh: Could not resolve hostname hg.code.sf.net: Name or service not known
abort: no suitable response from remote hg!

PS: I executed that from Ubuntu running VMWare player. There is no proxy server.

Thank You
