我正在尝试在 Ubuntu 计算机上使用 Openswan（版本 5.6.2）启动 VPN。
但是当我启动以下命令时，它显示“缺少配置名称”：
sudo swanctl --initiate vpn-name
initiate failed: missing configuration name
这是 IPSEC Statusall 命令的输出：
sudo ipsec statusall
Status of IKE charon daemon (strongSwan 5.6.2, Linux 5.3.0-1032-aws, x86_64):

以下是配置/etc/ipsec.conf
cat /etc/ipsec.conf
# ipsec.conf - strongSwan IPsec configuration file
# basic configuration
config setup
strictcrlpolicy=no
uniqueids = yes
charondebug="all"
#nat_traversal=yes
# strictcrlpolicy=yes
# uniqueids = no
# Add connections here.
# Sample VPN connections

答案1
swanctl 是一个新的、可移植的命令行实用程序，用于使用 vici 界面配置、控制和监视 IKE 守护进程 Charon。它是在 StrongSwan 5.2.0 中引入的。
swanctl 独立于 starter、ipsec.conf 或 ipsec 脚本工作，是所有平台上可用的轻量级替代方案。
swanctl配置完成后即可使用/etc/swanctl/swanctl.conf。
如果您配置了旧版本ipsec.conf，则需要使用以下命令启动连接：
sudo ipsec up vpn-name
