我正在尝试通过 VPN 进入我的工作地点。以前这对我来说是可行的，但现在我不知道发生了什么，它只是停止工作了。我确实更新了我的 Linux 机器。
我正在运行：
juniper network connect v8.0
gentoo linux

对于具有 rwx 权限的 root 用户来说，目录 /root/.juniper_networks 确实存在，但第 2 行仍然会出现错误。此外，管理员告诉我这是成功验证，上面的日志中也这么说，但随后不久又出现了错误。
答案1
你有这句话，
ncsvc[p4202.t4202] dsssl.error ive_cert_hash = 9adf4asdffadsfa2fas5f2asdfas3e, computed_hash = 9fadfasfdfasdfdasdfa25fasdf37 (DSSSLSock.cpp:1563)
这表明您服务器上的自签名证书与向您提供的证书不匹配。您可以尝试通过以下方式检查服务器上的证书安装情况：https://cryptoreport.thawte.com/checker/除此之外，它看起来像是一个证书问题，而不是连接/权限/...问题。
