Severity: important
When I try to connect to a valid database with a valid user/password
on localhost I get an error like this:
org.openstreetmap.osmosis.core.OsmosisRuntimeException: Unable to
establish a database connection.
at
org.openstreetmap.osmosis.core.apidb.common.DatabaseContext.getPostgresConnection(DatabaseContext.java:111)
[...]
Caused by: org.postgresql.util.PSQLException: The connection attempt
failed.
at
org.postgresql.core.v3.ConnectionFactoryImpl.openConnectionImpl(ConnectionFactoryImpl.java:150)
[...]
Caused by: java.net.SocketException: Network is unreachable
at java.net.PlainSocketImpl.socketConnect(Native Method)
[...]
The reason is seemingly that the Java driver tries to connect to the
local IPv6 address for "localhost", here's what my localhost
configuration is like:
$ sudo ifconfig lo
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
If I then do:
sysctl -w net.ipv6.conf.all.disable_ipv6=1
Which changes it to this:
$ sudo ifconfig lo
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
I can connect successfully to the PostgreSQL database from Java.
