[jira] Created: (DERBY-1432) derbynetmats/NSinSameJVM.java fails to
run due to Warning "UnknkownHostException: dyn" on Linux with DHCP
generated hostname
derbynetmats/NSinSameJVM.java fails to run due to Warning "UnknkownHostException: dyn<xx>" on Linux with DHCP generated hostname
--------------------------------------------------------------------------------------------------------------------------------
Key: DERBY-1432
URL: http://issues.apache.org/jira/browse/DERBY-1432
Project: Derby
Type: Bug
Components: Test
Versions: 10.1.2.1, 10.1.3.0
Environment: Linux Operating Systems using DHCP IP address *and* hostname generation
Reporter: Stan Bradbury
Priority: Minor
The test derbynetmats/NSinSameJVM.java reports that the Network Server failed to start and aborts on Linux machines that use DHCP to generate a hostname that reflects the generated IP address (e.g. hostname like: dyn<xx> where <xx> is the IP address string like 216101116144). Network server does, in fact, start.
derby.log entry:
Warning: UnknkownHostException: dyn<someIP>: dyn<someIP>.
Server is ready to accept connections on port <some-port>.
derbyall.sum entry:
> FAIL Network Server did not start
Test Failed.
*** End: NSinSameJVM jdk1.5.0_07 DerbyNetClient derbynetmats:derbynetmats 2006
Appears to be related to reported JVM issue: Bug ID: 4665037
Synopsis InetAddress.getLocalHost() ambiguous on Linux systems

[jira] Commented: (DERBY-1432) derbynetmats/NSinSameJVM.java fails

Andreas Korneliussen commented on DERBY-1432:
---------------------------------------------
The derbynetmats/NSinSameJVM.java test fails often with this error on Windows in the nightly regression tests. I think the reason is that the test starts the network server on ip "0.0.0.0" , which is a special-use interface. On windows, you may often see that network interfaces which are down, get the 0.0.0.0 address. I think this could be fixed by using localhost instead.
I do not see how this error is related to the RFE in the bugtraq database: the RFE is to have InetAddress.getLocalHost().. return an IP address which is something else than the loopback interface (which again contradicts the current JavaDoc of InetAddress.getLocalHost())

----------------------------------------
Hi Ole, check the derby.logs for these failures on your machines. They will contain a "Warning: UnknkownHostException: dyn<someIP>: dyn<someIP>." if this is the same failure as DERBY-952.
