router openwrt

Hardware environment:Development Board for RT5053F3G module for ZTE MC2176 Telecom EditionHere are the steps to do Add vid, PIDThe method of obtaining the VID and PID is to plug the device into the computer and run the LSUSB command under Linux.or follow the Wireless module driver manual to add the product support IDs to the Option.c fileopenwrt-1407 in the following location: Build_dir/target-mipsel_24kec+dsp_uclibc-0.9.33.2/linux-ramips_mt7620n/linux-3.10.49/drivers /usb/serial/option.c

Brief introductionUbus is a message bus introduced by the new OpenWrt, and the main role is to implement information interaction between different applications.Ubus runs the UBUSD process in the background after startup, and the process listens for a UNIX socket to communicate with other applications. Other applications can communicate with each other based on the interface provided by Libubox (or its own implementation).The main ways to use Ubus are:

Embedded file System general user perform SU root switch root user will prompt errorSu:must is suid to work properlyis due to BusyBox permissions, you need to change the permissions of BusyBox to 4755.In OpenWrt, it is not possible to modify the BusyBox under the staging_dir/target-mipsel_24kec+dsp_glibc-2.21/root-ramips/bin/directly, because it is overwritten after the re-make. The workaround is to select the desired command in BusyBox, then move the

Current SituationOpenWrt Default user name is root, but the default is no password, so SSH is not turned on by default, but Telnet is used without password, when the root password is set, then ssh on, telnet off. And the convenience of SSH is more than telnet,telnet in the case of product testing and use, so there is no way to let the two coexist?Step OneModify the Telnet self-launch script to remove the password and SSH-related judgments, as followsstart() {# if ( ! has_ssh_pubkey \#

First of all, what is OpenWrt?In fact, it is also a kind of embedded, mainly used in the routing aspect, the function is very powerful, can develop their own required functions, and so on.
