Hi,

I'm having trouble with R10B-7 and using SSL for communication between
distributed nodes.

REPRODUCTION STEPS: follow these instructions...

http://erlang.se/doc/doc-5.4.8/lib/ssl-3.0.7/doc/html/ssl_distribution.html

PROBLEM:
The instructions work on R10B-6. On R10B-7, when you get to the step:

$ erl -boot /home/me/ssl/start_ssl -proto_dist inet_ssl -sname ssl_test
Erlang (BEAM) emulator version 5.0 [source]

Eshell V5.0 (abort with ^G)
(ssl_test_at_myhost)1>

The command actually produces no output and just hangs. Using "top"
shows that beam is using no CPU time, so it is perhaps some kind
of deadlock, rather than livelock. Hitting CTRL-C brings up the

BREAK: (a)bort (c)ontinue (p)roc info (i)nfo (l)oaded
(v)ersion (k)ill (D)b-tables (d)istribution

menu ok.

Thanks for any help you can offer,
Julian

Oops.

My apologies, it's not that command that causes the hang (although it
does crash out because SSL has not been provided with any certificates,
so the docs need updating).

The command that hangs is the next in the webpage:

$ erl -boot /home/me/ssl/start_ssl -proto_dist inet_ssl
-ssl_dist_opt client_certfile "/home/me/ssl/erlclient.pem"
-ssl_dist_opt server_certfile "/home/me/ssl/erlserver.pem"
-ssl_dist_opt verify 1 depth 1
-sname ssl_test

Again, my apologies,
Julian
