--remember doesn't

[b3taman]

Describe the bug

I set up my own proxy and discovered that --remember only creates a zero-byte ~/.config/croc/internal-dns file.

I ran find ~ -xdev -type f -exec stat -c "%y %n" {} + | sort -r | head -10 | sort -r to give me the 10 newest files after running croc as above, and the empty internal-dns is all I found.

To Reproduce

1. Run croc --remember --pass ./super-secret-password relay --ports 11111,11112,11113,11114,11115
2. Connect and transfer files.
3. Stop the relay with Ctrl+C.
4. Discover that nothing is remembered and that ~/.config/croc/ contains only internal-dns, which is empty.

Expected behaviour

Some kind of config file which is read and acted upon.

Version

croc version v9.6.5-8ab65d0

Additional context

1. Running without --remember doesn't create the internal-dns file.
2. Separately I tried croc config as per https://schollz.com/software/croc/, but that simply returned with securing channel...2023/10/13 17:27:54 room not ready.
