This is due to this line (gateway_bootstrap.py line 46) https://bitbucket.org/hpk42/execnet/src/9c14d7158790c3156c36ab720caa20273647967f/execnet/gateway_bootstrap.py?at=default#gateway_bootstrap.py-46

It tries to write and read back and catches the EOFError.

But trying to connect to SSH directly reports in:

#!

Permission denied (publickey).

从 execnet/gateway_bootstrap.py 第 46 行开始，这里 SSH 连接会写入、读回并捕获 EOFError。将此行为与报告的直接 SSH 输出进行比较，包括“Permission denied (publickey).”。当失败属于身份验证错误时，报告的 SSH 问题不会显示为 HostNotFound，即表示完成。
