我正在尝试访问我的 IBMi 上的 SSHD 服务器。但是我不断收到Permission denied (publickey,password,keyboard-interactive).。
我在 IBMi 上运行 v7r2
在运行命令将 yum 安装到分区之前，此方法一直有效。（Yum 命令有效，至少在 qp2term 中有效。）请遵循以下说明：[https://ibmi-oss-docs.readthedocs.io/en/latest/yum/README.html][1]
当我使用相同的用户密码登录 5250 调用 qp2term 会话并运行以下命令时，出现相同的错误\ssh test400调试
我对 Unix 或 Linux 还只是个新手，请帮忙。
我已经采取的步骤（我之前也进行了公钥认证）
ENDTCPSVR SERVER(*SSHD)并且STRTCPSVR SERVER(*SSHD)（多次以及每次 SSHD_config 更改后。）CHGUSRPRF USRPRF(user) HOMEDIR('/home/user')- 验证服务器是否实际运行 [Nav for i 网络 -> 服务器 -> TCP/IP 服务器 -> SSHD][2]
chown user /home/userchmod 0700 /home/user
结果drwx------ 6 user 0 45056 Mar 29 22:02 user
chmod 0700 /home/user/.ssh
结果drwx------ 2 user 0 8192 Mar 29 20:51 user/.ssh

# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.
# Configuration data is parsed as follows:
# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.
# Site-wide defaults for some commonly used options. For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.
