Hello, I'm not sure if it's covered by your commit or if it's something 
completely unrelated, but after upgrading from 3.32 to 4.1 (Debian 
testing), I see some non-fatal errors in pluto's log, like this:
=====
connection "bernibs-voda": bad right --id: illegal (non-DNS-name) 
character in name (ignored)
added IKEv1 connection "bernibs-voda"
=====

There are such errors for every connection that has a right value 
expressed as FQDN address. But in my case those names don't start with 
numbers and the corresponding connections work regularly.

To reproduce, try to create the following connection, restart ipsec and 
then check pluto's log:
=====
conn test
     auto=ondemand
     authby=secret
     left=192.168.10.22
     right=example.com
     #right=93.184.216.34
     rightsubnet=192.168.33.0/24
     ikev2=no
     ike=aes256-sha1;modp4096
     dpdaction=restart
     dpddelay=10
     dpdtimeout=30
     mtu=1400
=====

Now change right= from FQDN to IP address: for me the error message 
doesn't appear anymore.

Cesare.
