Subject: [PATCH] Use proto_dist from command line
|
|
|
369b33 |
|
|
|
369b33 |
Use protocol distribution value from command line when provided instead
|
|
|
369b33 |
of always using default value (inet_tcp) when trying to check epmd.
|
|
|
369b33 |
|
|
|
369b33 |
If provided more than one protocol distribution types, then use the
|
|
|
369b33 |
first one.
