+5 points for you! You are absolutely right and the proposed solution is right as well! Please merge!

@telmich But you were running:
[13:48] manager:~% cdist config -c ~/vcs/ungleich-dot-cdist/ -vvp10 -bj6 black{1..3}.place6.ungleich.ch server{1..4,6}.place6.ungleich.chwhere you haveserver{1..4,6}.place6.ungleich.ch.And
echo server{1..4,6}.place6.ungleich.chin bash gives:server1..4.place6.ungleich.ch server6.place6.ungleich.chCreated by: telmich
@darko-poljak no - you are missing shell expansion here: server{1..4} is in curly brackets and is being expanded by shell
Created by: darko-poljak
@telmich Is this wanted behavior?
Created by: darko-poljak
@telmich
Notice
server1..4.place6.ungleich.ch. IDNA splits host parts by dot, and..results in empty label.It seems, in bash, you cannot mix
..and,inside{}.So we should catch errors in
cdist/util/ipaddr.pyand output user friendly error.Created by: darko-poljak
@telmich And with multiple hosts but not jobs nor parallel mode? (without -p and without -j).
Created by: telmich
Not reproducible with one host only.
Created by: darko-poljak
@telmich And can you post whole output when running with -S (disable saving output stream)?
Does this happend if you specify only one host?
Created by: darko-poljak
@telmich And without -p ?
Created by: telmich
This also happens without -j:
