[Pgpool-general] connection problems

[Gerd König]

Hello,

looks like I'm too stupid to connect to pgpool instance from a remote host :-(
Why ?
If I call "psql -h infra01 -p 9999 -U postgres", where "infra01" is the host
serving pgpool, I get the error:
"
psql: could not connect to server: Connection refused
        Is the server running on host "infra01" and accepting
        TCP/IP connections on port 9999?
"

O.K., normally I would say, I have to check pg_hba.conf/pool_hba.conf.....but:

a) there is no pool_hba.conf, and in pgpool.conf the parameter "enable_pool_hba"
is set to "false"

b) pgpool is listening on port 9999 => pgpool.conf:
# Port number for pgpool
port = 9999

c) from host infra01 I can open psql via "psql -p 9999" without any problems =>
pgpool is running and really listens on that port

d) there are no firewall rules active on _both_ nodes =>
#> iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

e) some days ago, as on infra01 pgpool 2.1 was installed, everything worked
fine...?!??!

Can't I see the forest but the trees......what else can I check ?



many thanks in advance....GERD....

PS: pgpool version 2.2, postgresql version 8.3.5, both hosts running opensuse
