## Testing
|
||
|
|
[dig](https://linux.die.net/man/1/dig) is an excellent tool to dig deeper into the world of DNS queries. You can set queryopts at the end of the commandline starting with +. For example to set specific flags in the query one could write something like this:
|
||
|
|
```
|
||
|
|
# setting RA and RC flag but no RD flag
|
||
|
|
dig @127.0.0.1 -p 13337 git.comff.net A +retry=0 +nordflag +raflag +tcflag
|
||
|
|
|
||
|
|
# force using TLS (TCP port 853)
|
||
|
|
dig @127.0.0.1 -p 13337 git.comff.net A +retry=0 +tls
|
||
|
|
|
||
|
|
# force using TCP (TCP port 53)
|
||
|
|
dig @127.0.0.1 -p 13337 git.comff.net A +retry=0 +tcp
|
||
|
|
```
