Here's the official page for the error reported:

Google for 'ERROR 2006 (HY000)' yourself and you'll see quite a few hits.
So, let me get this straight ...
you've done an mysqldump of a 2.3 version db to an sql file.
That command using mysqldump looked like what?
you transferred the sql file to a local machine. How did you transfer that file to local machine? Might need to tar ball/zip the .sql file then transfer it to protect the text inside the .sql file.
Now you are trying to import the sql file into a new DB on the local machine ... show command you are using.
Have you turned on logging in MySQL? Is there an error log for MySQL you can reference?
