erlang 分佈式編程問題

這兩天業餘研究下erlang，看concurrent programming 的tutorial，發現例子裏的ping pong在我這裏怎麼弄都運行不了（一個mac os開兩個shell），後來在郵件列表裏找到了答案，

只需在啓動節點的時候加個@localhost就ok了，可能是新版本的問題，網上好多老版本的demo沒這個問題。可能是改進吧。

考慮到國慶 把內容也貼下

P.S.: After some experimenting on my Windows XP PC (although with a
newer version of erlang), I found there using "erl -sname
" and "net_adm:ping('')." would work. Using
"@localhost" didn't fix the issue on CentOS/OpenVZ.

When I called "erl_epmd:names()." on the XP machine it would list the
two nodes (even if I'd started without "@localhost" for sname, but in
that case ping didn't work).

However trying "erl_epmd:names(). " on my CentOS/OpenVZ machine just
froze for a long time and then eventually gave "{error,address}".

For whatever it might be worth to any other folks :-}
