If you use the dnscrypt installer there is a option to ignore the system dns entrys. Does no one read the things there? :D

Chuckle! I have been known to look at things, but not see them. (Facepalm)!
I definitely did see, & say ‘yes’ to dnscrypt asking if it should handle all the DNS duties.
But yes, you are right to doubt me..........
(Your later admission not withstanding). ;-)

I find this forum a great place to learn, particularly as my network/router knowledge is best described as ‘basic’.

MartinDEE,

Don't forget to re-start 'dnscrypt-proxy', as follows, whenever you make changes to the .toml file:

/jffs/dnscrypt/manager dnscrypt-start

[Starts it if NOT running and re-starts if already running] [emoji1]

What are all option ? This one is for restart and all the other are ? Please list

/jffs/dnscrypt/manager is a script !!! :)
It can be listed/read etc.

The 'case statement' at the end of the script is as follows (Options Highlighted):

So I turned on "Suspcious Query Logging" in the .toml configuration file.

I don't see any documentation of this feature in the wiki. Below is from the example .toml configuration file (with file and format un-commented to enable the feature.).

Code: 
############################################
#        Suspcious queries logging        #
############################################

## Log queries for nonexistent zones
## These queries can reveal the presence of mlware, broken/obsolete applications,
## and devices signaling their presence to 3rd parties.

[nx_log]

  ## Path to the query log file (absolute, or relative to the same directory as the executable file)

  file = 'nx.log'


  ## Query log format (currently supported: tsv and ltsv)

  format = 'tsv'
Here's a partial result showing representative frequency by the time-stamps. I get that dnscrypt is listening on 127.0.0.1, but am I supposed to be able to discern the source device, somehow?

What do I do with this information? Does dnscrypt block these, or do I need to do so myself with a blacklist?

Is too much information just a bad thing?

Basically the dnscrypt-start, kill all dnscrypt* process and start it. It is useful when you manually edit the toml configuration and want to restart dnscrypt-proxy to effect the new configuration.

If u looking for more option... go explore the toml file on your own.. if you have doubt with the toml file, you need to check with the developer and post your issue there. Suggest before you post, search the issue first. In any case, the dnscrypt-proxy is pretty stable now.

I was using 1.1.1.1 without dnsscrypt and now I am using 1.1.1.1 with dnsscrypt. The DNS response time increased from 20ms to 70ms. Is this due to DoH? dnscrypt itself tells me that the dns response from 1.1.1.1 is about 20-25ms, but my network monitoring tells me something different.. (The large number on the screenshot is the average of the last 30 days)
Click to expand...

Just a short update on this issue: After the update/installation/reconfiguration script was re-run from the start page, it installed the latest dnscrypt-proxy version 2.0.10 with the same options during configuration as before and then DNS latency reverted from 70ms back to 20-30ms.
 
@bigeyes0x0 Not sure whether it's the installer script that outputs this error, but when updating to 2.0.10 I got the following error:

Code: 
...
Info:  Found previous dnscrypt-proxy config file
 =>  Do you want to use this file without reconfiguring? [y/n]: y
 Info:  Use previous settings file
 Info:  Staring dnscrypt-proxy...
 *** Error:  Couldn't start dnscrypt-proxy
 *** Error:  Please send WebUI System Log to dev

However, looking at syslog it seems it actually (re-)started fine:

You need to crossreference the AB-Solution Logs with the nx.log.
All the nx.log contains is the queries that are for 'nonexistent zones' [as commented in the .toml file]

You need to read up and understand a little bit about DNS then it will make more sense.
(Yes, too much info is confusing :) ;) )

As a quick set of 'hints' read the following about 'DNS Resource Records'

DNS Resource Records
Zone DNS database is a collection of resource records and each of the records provides information about a specific object. A list of most common records is provided below:

  • Address Mapping records (A)
    The record A specifies IP address (IPv4) for given host. A records are used for conversion of domain names to corresponding IP addresses.

  • IP Version 6 Address records (AAAA)
    The record AAAA (also quad-A record) specifies IPv6 address for given host. So it works the same way as the A record and the difference is the type of IP address.

  • Canonical Name records (CNAME)
    The CNAME record specifies a domain name that has to be queried in order to resolve the original DNS query. Therefore CNAME records are used for creating aliases of domain names. CNAME records are truly useful when we want to alias our domain to an external domain. In other cases we can remove CNAME records and replace them with A records and even decrease performance overhead.

  • Host Information records (HINFO)
    HINFO records are used to acquire general information about a host. The record specifies type of CPU and OS. The HINFO record data provides the possibility to use operating system specific protocols when two hosts want to communicate. For security reasons the HINFO records are not typically used on public servers.

    Note: Standard values in RFC 1010

  • Integrated Services Digital Network records (ISDN)
    The ISDN resource record specifies ISDN address for a host. An ISDN address is a telephone number that consists of a country code, a national destination code, a ISDN Subscriber number and, optionally, a ISDN subaddress. The function of the record is only variation of the A resource record function.

  • Mail exchanger record (MX)
    The MX resource record specifies a mail exchange server for a DNS domain name. The information is used by Simple Mail Transfer Protocol (SMTP) to route emails to proper hosts. Typically, there are more than one mail exchange server for a DNS domain and each of them have set priority.

    Example:
    msn.com MX preference = 5, mail exchanger = mx2.hotmail.com
    msn.com MX preference = 5, mail exchanger = mx3.hotmail.com
    msn.com MX preference = 5, mail exchanger = mx4.hotmail.com
    msn.com MX preference = 5, mail exchanger = mx1.hotmail.com

    msn.com nameserver = ns3.msft.net
    msn.com nameserver = ns5.msft.net
    msn.com nameserver = ns4.msft.net
    msn.com nameserver = ns1.msft.net
    msn.com nameserver = ns2.msft.net
    mx1.hotmail.com internet address = 65.55.92.184
    mx1.hotmail.com internet address = 65.54.188.72
    mx1.hotmail.com internet address = 65.54.188.94
    mx1.hotmail.com internet address = 65.54.188.110
    mx1.hotmail.com internet address = 65.54.188.126
    mx1.hotmail.com internet address = 65.55.37.72
    mx1.hotmail.com internet address = 65.55.37.88
    mx1.hotmail.com internet address = 65.55.37.104
    mx1.hotmail.com internet address = 65.55.37.120
    mx1.hotmail.com internet address = 65.55.92.136
    mx1.hotmail.com internet address = 65.55.92.152
    mx1.hotmail.com internet address = 65.55.92.168

  • Name Server records (NS)
    The NS record specifies an authoritative name server for given host.

  • Reverse-lookup Pointer records (PTR)
    As opposed to forward DNS resolution (A and AAAA DNS records), the PTR record is used to look up domain names based on an IP address.

  • Start of Authority records (SOA)
    The record specifies core information about a DNS zone, including the primary name server, the email of the domain administrator, the domain serial number, and several timers relating to refreshing the zone.

  • Text records (TXT)
    The text record can hold arbitrary non-formatted text string. Typically, the record is used by Sender Policy Framework (SPF) to prevent fake emails to appear to be sent by you.

Interesting, thanks for the redirection to ABS logs. Looks like my Dish Hopper and Sling add-on are very busy. I'll dig into it further, but the Dish Hopper is querying 168.2.109 (missing an IPV4 field) for some reason, for example. Bizarre.

Any thoughts as to why, and if one would care?
 
I've wondered why I occasionally and suddenly lose outbound connections. I just noticed that dnscrypt crashed and, voila, no outbound. Restarting dnscrypt resolved the issue. No forensics about the cause.

Check that something is not truncating the line when you are reading the logs.
I am not aware of anything that would accept an ip address 168.1.109 without an error !!!

Dnscrypt-proxy should not crash !!!
Investigate what else was happening and check all available logs for clues.
 
Just a quick heads up if anyone, especially those that are not in the US, decide to use Cloudflare's DoH 1.1.1.1 or 1.0.0.1 with dnscrypt-proxy.

Most if not all of your CDN traffic will be served via the US.. So while you are shaving off +100ms of your DNS queries you are actually slowing down your browsing experience! There's also the issue of whether you really want your traffic served via the US which is a privacy concern for non-US based privacy conscious users.

Google's DoH fares somewhat better but seeing that its core business is advertising, I'd skip it too.

We need European and Asian Anycast and DoH capable DNS service providers with their source DNS hosted within their regions... if you know of any, please share. Until then, I'll continue on using a private EU-based Dnscrypt/DoH instance.

Hope this helps?
 
The referenced DCs are presence points aka PoPs. The point of my post was on recursive servers - the servers that are used to build cloudflare's cache for 1.1.1.1/1.0.0.1 services ... These appear to be based in the US which is why content delivered over CDNs is mainly delivered via the US.

So unless cloudflare creates local/regional recursive services in those presence points you referenced, most CDN services will continue to serve you content via the US.

Well, based on my traceroute and ping outputs below (and geolocation of the IPs), I would says that 1.1.1.1/1.0.0.1 have local copies in Vienna/Austria (Cloudflare has a local presence).

The tranceroute shows that the 1.1.1.1 is only routed via the local Viennese network (aorta.net/Vienna) and also terminates there to 1.1.1.1 (same for 1.0.0.1).
The great ping rates around 15 ms also show that the DNS servers are really nearby! :cool:

Now I am really temped to give it a try (over my current setup to DNS servers in Germany, France and Italy)... :rolleyes:

You are totally missing the point. I am getting great query times too but most CDN delivered content is being served from the US versus the nearest CDN PoP.

Please read up on CDN and Anycast DNS with single and multi recursive sources. You'll save me a few grey hairs.
 
And there's also the matter of eDNS-client-subnet support - unless it's supported at both levels (the DDNS and the CDN), you won't get optimal results.

I just noticed that sites started reporting that they could not be found, then sometimes working. Then I saw in the system log that dnscrypt stopped, for some reason at 11:49. I restarted it manually at 11:52 and browsing works again.

I hear what you’re saying. My real world experience though, is great.
Cloudflare via DoH is easily as ‘snappy’ as my ISP.

Quad9 & Google are both like wading through wet cement by comparison. (A location specific problem I’d imagine).

Re privacy; locally, ISP’s are required to store the last two years worth (metadata) of everything done online, so that horse has bolted.........
