Ошибки при определении SSH отпечатков пальцев новых экземпляров

Question

я попытался создать новый кластер, используя OpsCenter 5.2.4, но я получил эту ошибку:

Error: Fingerprint Detection failed: sequence item 0: expected string, NoneType found 

в логах OpsCenter /var/log/opscenter/opscenterd.log Я получил эту ошибку:

Любая идея?

Приобретение OpsCenter здесь. Это говорит о том, что операция не удалась:

2016-10-09 10:02:06+0000 [] ERROR: /usr/bin/ssh-keyscan had some issues: 
    stdout= 
    stderr=  getaddrinfo None: Name or service not known 

Возможно, это связано с сетью. Можете ли вы запустить ssh-keyscan против рассматриваемого хоста или вы можете ssh к нему вообще? Я предполагаю, что нет, и вам нужно возиться с сетевыми брандмауэрами, iptables и/или вашей маршрутизацией, пока вы не сможете ssh от сервера OpsCenter до целевых хостов.

Также обратите внимание, что функции обеспечения в OpsCenter 6.0.x на несколько лет опережают то, что находится в 5.2.x. Я настоятельно рекомендую вам обновить.
