我正在尝试使用 openconnect (协议 Global Protect) 连接到企业 vpn：
perret at perret-pc in ~
$ openconnect --protocol=gp [vpn-address]
POST [vpn-address]/ssl-vpn/prelogin.esp?tmp=tmp&clientVer=4100&clientos=Linux
Connected to 185.183.115.255:443
SSL negotiation with [vpn-address]
Connected to HTTPS on [vpn-address]
POST [vpn-address]/global-protect/prelogin.esp?tmp=tmp&clientVer=4100&clientos=Linux
SAML authentication via POST to <html>
<body>
<form id="myform" method="POST" action="[corporate-address]/auth/realms/vpgrp/protocol/saml">

is required.
Must specify destination form field by appending :field_name to login URL.
Failed to parse server response
Failed to obtain WebVPN cookie
我不太确定这部分：
Must specify destination form field by appending :field_name to login URL.
我以为会是这样的：
openconnect --protocol=gp [vpn-address]:myform
POST https://vpn.veepee.tech:myform/ssl-vpn/prelogin.esp?tmp=tmp&clientVer=4100&clientos=Linux
getaddrinfo failed for host 'vpn.veepee.tech:myform': Name or service not known
Failed to open HTTPS connection to vpn.veepee.tech:myform
Failed to obtain WebVPN cookie
但正如您所见，它也不起作用。
任何想法？
这可能和这部分源代码有关：https://github.com/dlenski/openconnect/blob/master/auth-globalprotect.c#L91
