[strongSwan] Looking for a way to debug resolve plugin

[Pavel Nikulin]

Hello,

I have an issue with resolve plugin failing to set nameserver records.
Following shows up in the log:

authentication of 'xxxxx' with EAP successful
IKE_SA xxxxx established between 192.168.0.140[192.168.0.140]...xxxxx[xxxxx]
scheduling reauthentication in 3333s

x.x.x.x/32 xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx/128 === 0.0.0.0/0

connection 'xxxxx' established successfully

I use openresolv (https://roy.marples.name/projects/openresolv) as my
resolvconf implementation.

I there any way to get more verbose output from resolve plugin? Any
suggestions about the cause?
