ssh застряг при передачі команди, але вхід без команди працює

2

Я вмію sshобробляти xyz:

$ ssh xyz 
mitchus@xyz's password: 
Last login: Fri Sep  1 12:37:10 2017 from 192.168.1.23
mitchus@xyz:~$

але я не можу scp, і я не можу надіслати команду через ssh. Так, наприклад, ssh xyz echo helloзастрягає.

Я вже перевіряю інтерактивний сеанс у своєму .bashrcскрипті користувача сервера , а також намагався модифікувати /etc/ssh/sshd_configвикористання

UsePAM no

але це нічого не змінило. Якщо це доречно, я намагаюся підключитись із MacOS 10.11 до вікна Ubuntu 16.04, обидва в одній мережі Wi-Fi.

Ось результат ssh -vvv xyz echo hello:

Що відбувається під час підключення до іншої серверної машини? Або з іншої клієнтської машини? Це повинно сказати, чи проблема є у клієнта чи сервера (або, можливо, вона проявляється лише для цієї пари клієнт-сервер). Якщо можете, спробуйте також різних користувачів. Якщо у вас немає доступу до іншого комп'ютера / ОС, то підключення до 127.0.0.1(як на MacOS, так і на Ubuntu) може виявити щось корисне.

Як уже згадувалося в запитанні, ОП запрацював ssh, додавши -tопцію, яка змушує створити віртуальний пристрій TTY, але намагалася працювати scp, який використовує ssh для копіювання файлів між віддаленими системами.
Щоб примусити створити віртуальний пристрій TTY для scp, -oпараметр з подальшим списком параметрів ssh написаний у тому ж стилі, що і для файлу конфігурації ssh, тому в цьому випадку -o RequestTTY=force.
