[strongSwan] route-client error

[Claude Tompers]

Hi,

I'm sorry to bother you again on this topic, but I really would like to get it to work as non-privileged user.
Charon on the other hand, works like a charm, sadly pluto doesn't.

This is my setup now :
	strongswan runs as user vpn
	In ipsec.conf, I added :  leftupdown="sudo ipsec _updown"
	In /etc/sudoers, i added : vpn     ALL = NOPASSWD: /usr/local/sbin/ipsec

Still I get the error below on the interface version.

Can you please help me on this ? Any idea is appreciated.

thank you very much

kind regards,
Claude
