    DNScrypt dnscrypt installer for asuswrt

    Just an FYI... this doesn't really "pre-resolve" anything, it just sends the query to 8.8.8.8 to resolve that specific domain name. Know the difference between "server=/domain/ip" and "address=/domain/ip".

    Compilation error for asuswrt-merlin.ng with rt-ac86u

    Change link /bin/sh to point to the bash shell, not dash. Always compile from a fresh backup copy of the source code. Do not type anywhere make clean. Do not try to compile a different target after successfully compiling another one.

    DNSMasq Wildcard Round-Robin DNS

    EDIT: for your purposes, you could change the iptables rule from REDIRECT to DNAT, to use the public DNS resolvers, since you aren't using dnscrypt-proxy. This guy shows how to do basic round-robin using iptables. It requires the statistic module extension to iptables...

    [rt-ac86u] ioctl command wrong in 64 bit system from 32 bit user code

    I apologize in advance for posting this to Merlin's forum because the issue is not about his firmware. However... some people will probably encounter this issue at some point. I have a program that talks to a driver using ioctl. It works perfectly when both the driver and the program are...

    Swap File Mount/Unmount

    I don't think it's necessary. However, for security reasons you could disable it and then fill it with zeros, just before system shutdown. Sometimes the swap space contains fragments of passwords or encryption keys.

    rt-ac86u: vlans how to do it?

    Just trying to figure how to do vlans for the new RT-AC86U router. I'm making progress but still no cigar. There is no robocfg. Broadcom has a new programm called vlanctl. I want to use Ethernet port#4 on the router as a trunk for a managed switch with vlan14 as a guest network. Test...

    [Release 382] Asuswrt-Merlin 382.1 is now available

    This is my fault because I'm compiling directly from Github with some Asus' features turned off. I compile 382.2-alpha2 for my RT-AC68U with BWDPI=n. I had to create a stub for the function dump_dpi_support() in httpd, just to get it to compile, like this: // HACK: fix prebuilt web_hook.o #if...

    Difference between my compiled GPL versus ASUS stock firmware

    Your compiled programs will most always have a different md5sum, even when the source code is the same. It's your C compiler and linker that cause this. It's quicker to compare the file sizes. If the size difference is > 40 bytes then you've probable got different source code. Here's the...

    Difference between my compiled GPL versus ASUS stock firmware

    After compiling the 382.18547 GPL source code for RT-AC68U, I noticed that it is 659,456 bytes smaller than the same firmware released by ASUS. Upon closer inspection the biggest size difference, I can see, is the BWDPI kernel modules found here: /usr/bwdpi. Maybe someone forgot to strip the...

    Looking for network hardware options. Spend my money plz...

    May, 2018 is the end-of-days for Linux 4.1 kernel, and thus the new RT-AC86U ? https://www.kernel.org/category/releases.html My RT-AC68U is very weary, but still some fight left in her. I'm holding out to the very end with my RT-AC68U and 380.x Asuswrt-Merlin.

    RT-AC87U bricked?

    Do not connect the Vcc pin. I was just saying that +3.3V TTL means that binary "1" is 3.3V, and binary "0" is 0V. If you got a 3.3V/5V jumper on your USB-to-serial adapter, make sure it's on 3.3V. If you have an oscilloscope, you can watch the TX and RX pins to verify that it is 3.3V TTL...

    RT-AC87U bricked?

    Yes, the TX and RX pins use +3.3V TTL signal.
