Question

Я разрабатываю программу java для подключения к серверу windows через ssh. Для этого я использовал jcraft на java. И ssh-сервер - copSSH. Осуществление бросков

Error: com.jcraft.jsch.JSchException: Algorithm negotiation fail

ошибка на java. В то же время он показывает

fatal: Unable to negotiate with 192.168.28.111: no matching cipher found. Their offer: aes128-cbc,3des-cbc,blowfish-cbc [preauth]

на CopSSH.

И CopSSH хозяин следующие версии

OpenSSH_7.1p2, OpenSSL 1.0.2e 3 Dec 2015

Может ли один предложить исправление для него?

Answer 1

Это происходит из-за отсутствия поддержки устаревших шифров в последних выпусках OpenSSH. Проверьте решение this Copssh FAQ. Фоновая информация также может быть найдена here.

Answer 2

Последняя jcraft jar исправляет проблему
