Помощь для синхронизации Unison

Question 1

Я пытаюсь заставить Unison синхронизировать две папки, одну на моем компьютере Ubuntu и одну на моем Mac. (Мне удалось запустить Rsync раньше, но я хочу двунаправленную синхронизацию, поэтому я смотрю на Unison). В качестве теста я создал простую папку на моей машине Ubuntu с именем syncTest, которая содержит два текстовых файла: file1.txt и file2.txt. Затем я использовал эту команду:

unison ~/syncTest/ ssh://admin@Macbook.local//Users/Admin/syncTest

Вывод команды таков:

Contacting server...Connected [//MacBook.local//Users/Admin/syncTest -
> //notre-ubuntu//home/notre/syncTest]
Looking for changes
Warning: No archive files were found for these roots, whose canonical 
names are:
     /home/notre/syncTest
    //MacBook.local//Users/Admin/syncTest
This can happen either
because this is the first time you have synchronized these roots, 
or because you have upgraded Unison to a new version with a different
archive format.  


 Update detection may take a while on this run if the replicas are 
 large.


 Unison will assume that the 'last synchronized state' of both 
 replicas was completely empty.  This means that any files that are 
 different will be reported as conflicts, and any files that exist 
 only on one replica will be judged as new and propagated to the other 
 replica. If the two replicas are identical, then no changes will be 
 reported.


 If you see this message repeatedly, it may be because one of your 
 machines is getting its address from DHCP, which is causing its host 
 name to change between synchronizations.  See the documentation for 
 the UNISONLOCALHOSTNAME environment variable for advice on how to 
 correct this.

В этот момент больше ничего не происходит. Кажется, он сидит бесконечно на моем компьютере Ubuntu. Любые идеи о том, что может пойти не так?

Спасибо!
