这似乎是network-manager-openconect-gnomeUbuntu 18.04+中的一个新问题
我安装sudo apt install network-manager-openconnect-gnome以获得 gnome 与 opeconnect 和Cisco AnyConnect 兼容 VPN (openconnect)的集成
顺便说一句（这实际上可能是相关的），我这样做是为了获取*.local要解决的地址：
sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf根据 systemd 文档dns先搬进mdns4_minimal去/etc/nsswitch.conf
如果我通过 gnome 网络管理器使用 openconnect 连接到 VPN，VPN 地址（工作站点）无法解析。常规站点继续按预期工作。
如果我在命令行上使用 openconnect 连接到 VPN sudo openconnect vpn.mycompany.com，VPN 地址（工作站点）会解析。常规站点继续按预期工作。
我想我会检查一下这些 VPN 连接方法之间是否有任何区别/etc/resolv.conf，果然，有一个：
命令行上的openconnect（工作）：
#@VPNC_GENERATED@ -- this file is generated by vpnc
# and will be overwritten by vpnc

# This is a dynamic resolv.conf file for connecting local clients directly to

# Third party programs must not access this file directly, but only through the

openconnect gnome 集成（不工作）：

如果我删除（或注释掉） nameserver 192.168.1.1，这是工作文件和不工作文件之间的内容差异......一切都按预期工作。我可以解析公司内部的地址，并且常规站点按预期工作。
Fedora 不会发生这种情况。一切都是开箱即用的。我不确定为什么该network-manager-openconnect-gnome软件包的工作方式不同，或者是否有一种方法可以使其在没有任何一个的情况下工作
- 手动编辑文件。
openconnect从命令行 使用该工具并保持终端打开运行该命令。
