# Server Configuration
|
|
|
|
Currently, smartdns provides three server modes: UDP, TCP, and DOT.
|
|
|
|
## UDP Server
|
|
|
|
1. Configure with the `bind` parameter. For example:
|
|
|
|
```shell
|
|
bind 0.0.0.0:53@eth0
|
|
bind [::]:53@eth0
|
|
bind :53@eth0
|
|
```
|
|
|
|
Options:
|
|
|
|
* @eth0 indicates that it only provides services on the corresponding NIC.
|
|
* [::]:53 indicates that it listens to both IPV6 and IPV4 addresses.
|
|
* :53 represents listening to IPV4 addresses.
|
|
|
|
## TCP Server
|
|
|
|
1. Configure with the `bind-tcp` parameter. For example:
|
|
|
|
```shell
|
|
bind-tcp 0.0.0.0:53@eth0
|
|
bind-tcp [::]:53@eth0
|
|
bind-tcp :53@eth0
|
|
```
|
|
|
|
1. Optional, the `tcp-idle-time` parameter controls the TCP idle disconnect time.
|
|
|
|
```shell
|
|
tcp-idle-time 120
|
|
```
|
|
|
|
## DOT Server
|
|
|
|
1. Configure with the `bind-tcp` parameter. For example:
|
|
|
|
```shell
|
|
bind-tcp 0.0.0.0:53@eth0
|
|
bind-tcp [::]:53@eth0
|
|
bind-tcp :53@eth0
|
|
```
|
|
|
|
1. Set certificate and key files
|
|
|
|
```shell
|
|
bind-cert-file smartdns-cert.pem
|
|
bind-cert-key-file smartdns-key.pem
|
|
bind-cert-key-pass pass
|
|
```
|
|
|
|
Options:
|
|
|
|
* `bind-cert-file`: Specifies the certificate file path.
|
|
* `bind-cert-key-file`: Specifies the certificate key file path.
|
|
* `bind-cert-key-pass`: Specifies the password for the certificate key file. (Optional)
|
|
|
|
Note:
|
|
|
|
If these three parameters are not specified, smartdns will automatically generate a self-signed cert `smartdns-cert.pem` and `smartdns-key.pem` key file in the `/etc/smartdns` directory, with CN as smartdns.
|
|
|
|
1. Optional, the `tcp-idle-time` parameter controls the TCP idle disconnect time.
|
|
|
|
```shell
|
|
tcp-idle-time 120
|
|
```
