Wow - I've been struggling with this for like 4 hours now :/ - hoping someone can help me.
Let's start with the requested file:
https://drive.google.com/file/d/1rU1v1Dd5L2h0yddzix1evRHw-MPtVnTA/view?usp=sharing
Additional info:
- Which dns server you selected during dnscrypt installtion
Automatic (no go at all), and the Google Anycast (still problems - see below)
- Which router you're using
RT-AC68U
- Firmware and its version
Merlin 384.6
Ok - so...
Basically, I can't get this to run - stable at least.
I'm running an RT-AC68U with Firmware 384.6.
This was all loaded fresh last night, the entire device was reloaded.
I did however restore my config from my stock ASUS firmware to prevent having to setup all my port forwards.
I then installed ab-solution and a basic entware install onto a 1 GB USB flash drive (older, just something I had sitting around). I played around with that stuff for a while and it seemed to work great. I then download amtm and tried to install this dnscrypt script.
I had tons of issues at first with my internet (presumably dns) just stopping to work and then all sorts of memory errors when trying to run this script. It took me a while to figure out - or at least I thought I did. As I'll show it appears that even without a swap file I have plenty of free memory, so why this script should give me memory errors I have no idea. However even without those errors I get very erratic behavior.
This will be lengthy because I want to include everything you may need to assist.
Let's start with the memory errors I mention. I don't have the ones from the initial install, but this is a good example of what I was/am getting. This particular output was when I tried to run the installer again with the configure option while I was experiencing connection issues:
Code:

I immediately exited from this and looked at my free memory:
Code:
admin@RT-AC68U-4C30:/jffs/scripts# free
total used free shared buffers cached
Mem: 255700 101024 154676 0 356 11140
-/+ buffers/cache: 89528 166172
Swap: 0 0 0
So you can see I had disabled my swap however there appears plenty of free memory - I don't see how this is the issue. Onto the next problem...
It seems I am only able to get things working (or at least the semblance of working - I am able to get to the internet) when choosing the
"google: Google DNS (anycast)" server as "Manual" during the install. Any attempt I make to use the "Automatic" option leaves me unable to communicate out. When I do get things working - it isn't for long. I observe the following running after a successful install:
Code:
4444 admin 777m S /jffs/dnscrypt/dnscrypt-proxy -syslog -config /jffs/dnscrypt/dnscrypt-proxy.toml
4463 admin 1424 S {manager} /bin/sh /jffs/dnscrypt/manager monitor-start
4477 nobody 778m S /jffs/dnscrypt/dnscrypt-proxy -syslog -config /jffs/dnscrypt/dnscrypt-proxy.toml -child
However anywhere from 30 seconds to a few minutes I will no longer be able to get out to any sites. When I look at running processes, all I see is:
Code:
admin@RT-AC68U-4C30:/jffs/scripts# ps | grep dnscrypt
4444 admin 777m S /jffs/dnscrypt/dnscrypt-proxy -syslog -config /jffs/dnscrypt/dnscrypt-proxy.toml
4463 admin 1424 S {manager} /bin/sh /jffs/dnscrypt/manager monitor-start
So it appears the "-child" process is killed some how - and I'm guessing that's important :/ ?
One strange thing (to me) is that when in this state I am unable to ping any sites at all with the
exception of google.com. I have checked and this information is not cached anywhere on my windows client - so I'm not sure why this behavior exists. Perhaps it has something to do with the fact that I have set using the Google server or 8.8.8.8 during the config? Not sure - but wanted to mention it.
So that's where I'm at. I'm at a total loss and have spend a lot of time getting this to load on what I would consider a pretty basic merlin install. I do have a couple of closing questions too to help in my understanding troubleshooting:
1) "Do you want to redirect all DNS resolutions on your network through this proxy? [y/n]:" - What does this mean? What is the difference of selecting yes/no here? My only guess is that if I set "n" then only my clients which are pointed to use this DNS server will go through proxy, whereas if I say "y" then the router will actually intercept ALL DNS queries that pass through it even if those clients aren't configured to use it? Please explain.
2) Why is the RNG and/or Timezone so important for this?
3) How can I stop/start these services manually while troubleshooting, or if they crash? Right now the only thing I can do that works is either reboot the device or do an uninstall/reinstall.
4) How can you determine if this is actually working (apart from being able to get out to the internet)?
The OP says to type:
Code:
nslookup -type=txt debug.opendns.com
but my output from that (even when everything else works) is:
Code:
C:\Users\xxxxxx> nslookup -type=txt debug.opendns.com
Server: router.asus.com
Address: 10.10.10.1
*** No text (TXT) records available for debug.opendns.com
I'm going to re-enable my swap file...even though I can't see how that's the issue and do a reinstall with the settings that worked for me and see if I'm still getting crashes. If not, and we say its a memory issue - how could it possibly be with so much memory showing available?
Thanks in advance for all the help I'll need!
