我可以改变initcwnd（TCP初始拥塞窗口）在我的 Debian Linux 系统上使用以下命令：
ip route change default via 123.123.123.241 dev eno1 onlink initcwnd 32
例子：
$ ip route show
default via 123.123.123.241 dev eno1 onlink
123.123.123.240/29 dev eno1 proto kernel scope link src 123.123.123.242
172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.0.1 linkdown
$ ip route change default via 123.123.123.241 dev eno1 onlink initcwnd 32
$ ip route show
default via 123.123.123.241 dev eno1 onlink initcwnd 32
123.123.123.240/29 dev eno1 proto kernel scope link src 123.123.123.242
172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.0.1 linkdown
$
重启后如何保留此更改？这是我的/etc/network/interfaces。这是添加此配置的正确位置吗？如何？
auto lo
iface lo inet loopback
auto eno1
iface eno1 inet static
address 123.123.123.242
netmask 255.255.255.248
network 123.123.123.240
broadcast 123.123.123.29
gateway 123.123.123.241
dns-nameservers 123.123.1.2 123.123.1.66
auto eno1:0
iface eno1:0 inet static
address 123.123.123.243
netmask 255.255.255.248
gateway 123.123.123.241
答案1
您可以将post-up- 命令添加到以下eno1部分/etc/network/interfaces：
iface eno1 inet static
...
dns-nameservers 123.123.1.2 123.123.1.66
post-up ip route change default via 123.123.123.241 dev eno1 onlink initcwnd 32
iface eno0:2 inet static
...
