我真的很想北VPN为了在睡眠/恢复事件中幸存下来,但是当然,如果远程端听不到我的笔记本电脑的声音,那么它就会断开连接。公平地说,我很乐意在睡觉前断开连接并在恢复时重新连接,只要我可以自动化它 - 我有通常的事情/usr/lib/systemd/system-sleep/sleep-stuff(以下)。
但这并不完全有效。恢复时,运行“nordvpn connect”,如果立即观察,路由表看起来不错(即从睡眠/恢复脚本中:
Kernel IP routing table

192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 wlp3s0
不幸的是,当我登录时,路由表已被“某些东西”切换回非 VPN 模式,我不知道是什么,可能是 NetworkManager:
$ netstat -rn

NordVPN 状态报告其正在运行:
$ nordvpn status
Status: Connected
Current server: au492.nordvpn.com
Country: Australia
City: Brisbane
Your new IP: 144.48.39.91
Current technology: OpenVPN
Current protocol: UDP
Transfer: 7.89 MiB received, 6.00 MiB sent
Uptime: 24 minutes 52 seconds
...但当然我必须进行额外的断开/连接,这很俗气。
有任何想法吗?
这是脚本(放入 /usr/lib/systemd/system-sleep/sleep-stuff 和 chmod +x 中):
#!/bin/sh
if [ "${1}" == "pre" ]; then
# before suspend
pgrep nordvpnd &> /dev/null && nordvpn status |grep -q 'Status: Connected' && {
# This will run as root, so root needs to have been initialised by
# nordvpn login at some time in the past.
/bin/nordvpn disconnect
}
elif [ "${1}" == "post" ]; then
# after resume
pgrep nordvpnd &> /dev/null && {
# This will run as root, so root needs to have been initialised by
# nordvpn login at some time in the past.
(
sleep 5 # I've tried sleep from 0 to 5
/bin/nordvpn connect
netstat -rn # routing table looks OK now but it gets zapped by something else later!!
) &
}
fi
这是在 Fedora-31 上。
答案1
经过一番思考后,我得出的结论是,不可能使用脚本重新启动nordvpn/usr/lib/systemd/系统睡眠/。
我已经满足于使用该脚本在睡眠时停止nordvpn,并且我必须记住在恢复时手动重新启动它。正如我正在使用的摇摆(1)、热键可以节省一些打字时间。
这是修改后的脚本:
#!/bin/sh
if [ "${1}" == "pre" ]; then
# before suspend
pgrep nordvpnd &> /dev/null && nordvpn status |grep -q 'Status: Connected' && {
# This will run as root, so root needs to have been initialised by
# 'nordvpn login' at some time in the past.
nordvpn disconnect
}
elif [ "${1}" == "post" ]; then
# after resume
