It looks like your connection is broken somehow, this might be caused by an OS level issue(firewall etc.) but not the application itself. To test if this is due to an OS level issue, I suggest you to try connect nREPL by telnet, here's how to start nREPL in a TTY mode, in any REPL session type following: -------------------------------------------------------------------------------------
(use 'clojure.tools.nrepl.server) (require '[clojure.tools.nrepl.transport :as t]) (*defonce* server (start-server :transport-fn t/tty :port 999)) ------------------------------------------------------------------------------------- then use telnet to connect to your new started nREPL server: telnet localhost 999. In my opinion, if you can get through by this way, then it's the app issue; otherwise it may caused by OS setting/issue. I wrote a small nREPL client(but in Lua: https://github.com/xiejianming/lua_nrepl_client) before. Something might cause your interest is that, by using this tool, you can check bencoded (default encoding protocol used by nREPL) messages sent by nREPL server directly; and you can also check something I call naked message from server. Just hope this will help you a little bit.... 在 2012年12月27日星期四UTC+8上午6时55分53秒，frye写道： > > Hi all, > > I'm trying to put together some nrepl > middleware<https://github.com/clojure/tools.nrepl#middleware>. > To get a basic understanding, I thought I would implement some simple nrepl > middleware in a test project as seen in *A)*.
