语境

我在办公室的 Raspberry Pi 和云中的 pfSense 防火墙之间建立了一条站点到站点的 IPSec 隧道。我在 Raspberry Pi 端使用 Strongswan。

问题

我的隧道建立并运行良好一段时间，但当它必须自行重新加密时，协商失败。

我是否缺少一些明显的东西？

重新生成密钥（这就是出错的地方）

我尝试过做什么

如果我通过 SSH 连接到 Raspberry 并运行ipsec restart，隧道将再次建立并正常工作，直到下一次重新生成密钥。

我无法理解为什么这些建议在重新生成密钥时不匹配（如果它们与初始连接匹配）。此外，我确实在 swanctl 配置文件中要求了不同的算法。

我尝试更改两侧的配置，但问题似乎始终位于 Raspberry 一侧（顺便说一句，pfSense 仅适用于响应程序）。

配置文件

/etc/swanctl/conf.d/myfile.conf

connections {
  gw-gw {
    local_addrs = RASPI_LAN_IP
    remote_addrs = PFSENSE_IP
    local {
      auth = psk
      id = RASPI_PUBLIC_IP
    }
    remote {
      auth = psk
      id = PFSENSE_IP
    }
    children {
      net-net {
        local_ts = RASPI_NET/24
        remote_ts = PFSENSE_NET/16
        start_action = start
        dpd_action = restart
      }
    }
    version = 2
    dpd_delay = 60
    mobike = no
    proposals = aes128-sha256-modp2048,default
  }
}

secrets {
  ike-1 {
    id-1 = RASPI_PUBLIC_IP
    id-2 = PFSENSE_IP
    secret = "MYPSK"
  }
}

我正在寻找一种方法来获取 Debian 和 RHEL 发行版的所有可升级软件包的列表。我知道 dpkg 在 中存储了一些数据/var/lib/dpkg/status，但我在那里没有发现任何表明给定包有可用于更新的新版本的信息。

我猜想因为apt list --upgradable列出所有可用的升级非常快，所以它必须依赖于一些缓存：它是否可以作为文件在某处使用？

我对 RHEL 的同一件事一无所知：dnf似乎有一个缓存/var/cache/dnf，但它主要是二进制文件。
