Hi
I installed pdns-backend-pipe and pdns (4.1.0) from https://repo.powerdns.com/ on a Centos7 (64bit) and tried to get PyPdnsRedis up an running. If I call the script manually I can add rr and query them

$ /work/pdns_redis.py -R 127.0.0.1:6379 -D mydomain.tld -r A -d 'myipaddress' -a 3600
$ /work/pdns-redis.py -R 127.0.0.1:6379 -D mydomain.tld -r A -q
[(mydomain.tld', 'A', '3600', 'myipaddress')]

But when I try to glue it together with PDNS via /etc/pdns/pdns.conf

launch=pipe
pipe-command=/work/pdns-redis.py -R 127.0.0.1:6379 -P
pipe-timeout=5000
loglevel=7

and query via pdns I get a SERVFAIL answer and the following in the logs

[PIPEBackend] Child closed pipe
Backend reported permanent error which prevented lookup (Child closed pipe), aborting
Backend error (retry once): Child closed pipe
Backend launched with banner: FAIL

I use pdns_redis.py on my server which runs a redis slave instance. If I just query pdns for a record I get SERVFAIL and in the logs

Dec 9 23:21:18 rbl3 pdns_server: Coprocess: Internal Error: You can't write against a read only slave.
Dec 9 23:21:18 rbl3 pdns_server: [PIPEBackend] coprocess returned a FAIL
Dec 9 23:21:18 rbl3 pdns_server: Backend reported condition which prevented lookup (coprocess returned a FAIL) sending out servfail

I just wonder if its really necessary to write to redis in case of answering a query?
I tried the -R and -W parameters but the error persists. So for me it seems that -W does not have any effect. I pointed it to the master redis but still got the error upon querying.
