# 多網卡下如何配置指定IP走某個路由器（適用于外網不通，但是釘釘服務器通的情況）

## 如何查看一個進程建立的網絡連接,方式一

- 查看進程pid `ps -ef|grep dingtalk`
- 查看進程的連接 `lsof -p pid -nP|grep TCP`
```
$ lsof -p 9542,9583,9587,9531 -nP |grep TCP
dingtalk 9531 lixu? 110u???? sock??????????????? 0,9????? 0t0 282904864 protocol: TCP
dingtalk 9531 lixu? 145u???? IPv4????????? 282864365????? 0t0?????? TCP 192.168.43.110:38536->203.119.215.179:443 (ESTABLISHED)
dingtalk 9531 lixu? 151u???? sock??????????????? 0,9????? 0t0 282904865 protocol: TCP
```

## 如何查看一個進程建立的網絡連接,方式二
- 查看進程的連接 `netstat -antlp|grep dingtalk`
```
$ netstat -antlp|grep dingtalk
(Not all processes could be identified, non-owned process info
?will not be shown, you would have to be root to see it all.)
tcp?????? 32????? 0 192.168.43.110:44560??? 106.11.208.166:443????? CLOSE_WAIT? 9531/dingtalk????? ?
tcp?????? 32????? 0 192.168.43.110:44562??? 106.11.208.166:443????? CLOSE_WAIT? 9531/dingtalk????? ?
tcp??????? 0????? 0 192.168.43.110:38536??? 203.119.215.179:443???? ESTABLISHED 9531/dingtalk
```

## 釘釘服務器加入到靜態(tài)路由表

```
sudo route add -host 203.119.201.180 gw 192.168.60.1 dev enp0s31f6
sudo route add -host 203.119.206.75 gw 192.168.60.1 dev enp0s31f6
sudo route add -host 203.119.206.251 gw 192.168.60.1 dev enp0s31f6
sudo route add -host 203.119.207.121 gw 192.168.60.1 dev enp0s31f6
sudo route add -host 203.119.207.122 gw 192.168.60.1 dev enp0s31f6
sudo route add -host 203.119.211.253 gw 192.168.60.1 dev enp0s31f6
sudo route add -host 203.119.214.249 gw 192.168.60.1 dev enp0s31f6
sudo route add -host 203.119.214.251 gw 192.168.60.1 dev enp0s31f6
sudo route add -host 203.119.215.179 gw 192.168.60.1 dev enp0s31f6
sudo route add -host 203.119.216.175 gw 192.168.60.1 dev enp0s31f6
sudo route add -host 111.6.226.253 gw 192.168.60.1 dev enp0s31f6
sudo route add -host 111.7.187.240 gw 192.168.60.1 dev enp0s31f6
sudo route add -host 111.7.187.241 gw 192.168.60.1 dev enp0s31f6
```

## 刪除路由

```
sudo route del -host 203.119.201.180
sudo route del -host 203.119.206.75
sudo route del -host 203.119.206.251
sudo route del -host 203.119.207.121
sudo route del -host 203.119.207.122
sudo route del -host 203.119.211.253
sudo route del -host 203.119.214.249
sudo route del -host 203.119.214.251
sudo route del -host 203.119.215.179
sudo route del -host 203.119.216.175
sudo route del -host 111.6.226.253
sudo route del -host 111.7.187.240
sudo route del -host 111.7.187.241
```
