SuffixMatchNode - dynamically add or remove records

[vecinohk]

Hello, is it possible to add and remove domains from the list while using SuffixMatchNode without restarting or reloading dnsdist?

I can load from a file at startup using dofile("/etc/dnsdist/suffix.lua"), but I need to dynamically add or remove records. However, I don't want to have to restart dnsdist to do this.

Thank you

It's technically possible but you have to delete and re-create the rule using rmRule then addAction again, as the rule makes a copy of the SuffixMatchNode for performance reason (avoiding the need to take a lock for each query/response processed).

Thank you for your response. Am I correct in understanding that I can:

1. Remove the current rule using rmRule.
2. Update the file dofile("/etc/dnsdist/suffix.lua") by adding new entries or removing old ones.
3. Finally, add the rule again using addAction?

Will this really work with that file? Or do I have to enter the items into addAction manually?

Thank you
