多网卡下如何配置指定IP走某个路由器（适用于外网不通，但是钉钉服务器通的情况）
# 多网卡下如何配置指定IP走某个路由器（适用于外网不通，但是钉钉服务器通的情况）
## 如何查看一个进程建立的网络连接,方式一
- 查看进程pid `ps -ef|grep dingtalk`
- 查看进程的连接 `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
```
## 如何查看一个进程建立的网络连接,方式二
- 查看进程的连接 `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
```
## 钉钉的服务器地址
tcp 0 90 192.168.60.26:60006 203.119.215.179:443 ESTABLISHED 4777/dingtalk
tcp 0 0 192.168.43.110:52588 203.119.215.179:443 ESTABLISHED 4777/dingtalk
## 钉钉服务器加入到静态路由表
```
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
```
## 删除路由
```
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
```
