ASUSWRT

一、使用

1.1 SSHD

开启ssh访问：Administration > System > Enable SSH

# Password-based login will use the same username and password as telnet/web access. 
# ssh <user>@<router>

1.2 Scheduled tasks (cron jobs)

You can create scheduled tasks using the standard crond service that runs on the router. You can put your cron tasks in /var/spool/cron/crontabs/. The file must be named "admin" as this is the name of the system user. Note that this location resides in RAM, so you would have to put your cron script somewhere such as in the jffs partition, and at boot time copy it to /var/spool/cron/crontabs/ using an init-start user script.

A simple way to manage your cron jobs is through the included "cru" command. Just run "cru" to see the usage information. You can then put your "cru" commands inside a user script to re-generate your cron jobs at boot time.

1.3 Mounting remote CIFS shares

You can mount remote SMB shares on your router. The syntax will be something like this:

mount \\\\192.168.1.100\\ShareName /cifs1 -t cifs -o "username=User,password=Pass" -o vers=2.0 (backslashes must be doubled.)

1.4 DNS Director

DNS Director (originally called DNSFilter, not to be confused with the company bearing the same name) is a feature that allows you to force specific devices on your network to use specific nameservers (DNS). This can be done globally, or on a per device basis. Each of them can have a different nameserver enforced. For example, you can have your LAN use Quad9's server to provide basic filtering of malicious sites, but force your children's devices to use CleanBrowsing's family server that filters out both malicious and adult content.

1.5 DNS Privacy

1.6 VPN Director

VPN Director lets you create rules to determine how your LAN traffic is redirected through your OpenVPN and WireGuard clients. You can create rules based on their local or remote IP (or even both). Subnets in CIDR notation (i.e. 192.168.50.0/24) can also be used to cover IP ranges.

二、编译官方/梅林固件

2.2 下载源码

cd $HOME
git clone https://github.com/RMerl/am-toolchains
git clone https://github.com/RMerl/asuswrt-merlin.ng
mkdir amng-build
rsync -a --del asuswrt-merlin.ng/ amng-build
