Cisco не позволяет подключиться по SSH

Случилась проблема: на Cisco устройство невозможно подключиться через SSH. Проблема особенна тем, что нельзя подключиться только с linux-версии OpenSSH (Gentoo пользователям повезло больше), а с bsd-версии все отлично.

Проблема:

ssh -v host

Решение (найдено в багзилле RedHat):

ssh -o HostKeyAlgorithms=ssh-rsa,ssh-dss -o KexAlgorithms=diffie-hellman-group1-sha1 -o Ciphers=aes128-cbc,3des-cbc -o MACs=hmac-md5,hmac-sha1 -v host

Для пущего порядка можно записать все это в .ssh/config.
