doh-client's Issues
[ERROR doh_client] Cannot listen to UDP address file descriptor 3: Invalid argument (os error 22)
For some time client worked. But after some system updates and/or reboot, it stopped.
Client version is 2.1.0

Hello!
I tried doh-client and got following errors:
ERROR [doh_client::http2] GetResponse: DNS parser error: TooMuchData
Question about `not a result of an error`
Hi!
I use doh-client on slow network and it works well, but there are plenty of error messages like:
ERROR [doh_client::http2] send_request: protocol error: not a result of an error
What does it mean? Is it because of my slow network or something else?
get method does not work with dns.google(8.8.8.8)
build
cargo b -r --no-default-featurescommand
./doh-client --get --cache-size 0 --listen-addr 127.0.0.1:9999 --domain dns.google --remote-host 8.8.8.8:443 /etc/ssl/cert.pem
dig @127.0.0.1 -p 9999 ocf.berkeley.eduerror message

Note:
- when use 8.8.8.8, remove --get works fine
- keep --get but use 1.1.1.1 works fine too.
Reference:
Use doh client using self signed certificates with doh-client v3.0.0.
Hi, I'm very interested in using your software to setup a private DoH Client.
However, when I try to start your doh client using client-side authentication i've got some problems.
For that I have:
- A private DoH Server configured with nginx with client side authentication, something like: https://fardog.io/blog/2017/12/30/client-side-certificate-authentication-with-nginx/
- The certificates were created using OpenSSL, therefore there is a CA certificate that I used to sign the server and the client certificates. Then, to execute the DoH client I have :
sudo ./doh-client /path/to/client/cert.pem -d dns.example.net -r DNSIP:443
- Then I get this error: [ERROR doh_client::remote::session] Could not connect to dns.example.net at DNSIP:443: IO Error: invalid certificate: UnknownIssuer
Additional info:
- I already succeed to connect to my dns server without the client-authentication part so I know my server is working. For that I execute: ./doh-client -d dns.example.net -r DNSIP:443
So my question is: is it possible to do what i'm trying to do with your DoH client?, did I miss something necessary to configure it well?
Thank you very much for your help.
Ivan Martinez.

Force retry if server responds with SERVFAIL
Hello!
First of all: this project is great. I came across it from the archlinux wiki and have started running it locally as my ISP appears to block DoT - let 'em try to block this!
I've been using the OpenNIC servers, which can be a touch unreliable. It can take a couple of queries for them to manage to get responses back. I realise this is an issue for them, really, but I'm wondering if doh-client might include configuration for retrying a specific number of queries with a time between them. Something like this:
[[upstream.upstream_ietf]]
url = "..."
weight = 50
retry_attempts = 5
retry_interval = 1
If it is a non-starter, don't worry - it is on me to choose more reliable servers, or maybe try to contribute to the OpenNIC project to solve my own problem. But if you can help it'd be great.
Cheers
John
error while loading shared libraries
Hi, I'm very interested in using your DoH client, however, I have got a problem when trying to install your software on Linux.
I did everything as suggested in the README file: compile, copying the binary and the config files to the respective locations.
Then when I try to start the service with systemctl sart doh-client, i have this error at the log:
/usr/bin/doh-client: error while loading shared libraries: libgcc_s.so.1: cannot stat shared object: Operation not permitted
Aditional info:
- cargo 1.51.0
- Ubuntu 18.04.5 LTS
- when i run the command ldconfig -p | grep libgcc_s.so.1; i got this :
marino@marino-PC:~$ ldconfig -p | grep libgcc_s.so.1
libgcc_s.so.1 (libc6,x32) => /usr/libx32/libgcc_s.so.1
libgcc_s.so.1 (libc6,x86-64) => /lib/x86_64-linux-gnu/libgcc_s.so.1
libgcc_s.so.1 (libc6) => /lib/i386-linux-gnu/libgcc_s.so.1
libgcc_s.so.1 (libc6) => /usr/lib32/libgcc_s.so.1
Do you have any idea why i'm getting this?,
Thank you very much.

"Could not start doh-client: IO Error: Could not add any certificates"
I built doh-client 3.1.2 on my Tiny Core Linux laptop.
On the laptop the client works fine.
When I try running it on my router (which uses same version of Tiny Core Linux), I am unable to start the client:
$ sudo doh-client
[ERROR doh_client] Could not start doh-client: IO Error: Could not add any certificates
The client does not have a verbose mode. I'm stuck, not sure how to troubleshoot this. Any ideas?
OS can't spawn worker thread: Operation not permitted (os error 1)
program verion 3.1.2, after some system updates i am getting:

connection error detected: frame with invalid size
I'm getting these errors on Fedora 35 with AdGuard Home stable running behind nginx:
[ERROR doh_client::remote::helper] HTTP2 connection close: connection error detected: frame with invalid size
[ERROR doh_client::handler] Could not retrieve DNS response from server: H2 Error: connection error detected: frame with invalid size
[ERROR doh_client::run] Could not handle request: Could not get response for: Dns *debug print of Dns struct*
(I'm using the cache flag to make sure that's not the cause and timeout/retries flags to speed it up until I get it working)
Am I doing this wrong? It works on my iPhone
