[jira] Created: (NET-347) FTPClient.listFiles throw exception when
connect to an IPv6 FTP server
FTPClient.listFiles throw exception when connect to an IPv6 FTP server
----------------------------------------------------------------------
Key: NET-347
URL: https://issues.apache.org/jira/browse/NET-347
Project: Commons Net
Issue Type: Test
Components: FTP
Environment: jdk 1.6, commons-net-2.2.jar
Reporter: jones wen
If i setup the IPv6 FTP server on localhost, it is OK.
If the IPv6 FTP server is on saloris 10(external host), FTPClient.listFiles() will throw below exception,
java.net.BindException: Cannot assign requested address: JVM_Bind
at java.net.PlainSocketImpl.socketBind(Native Method)
at java.net.PlainSocketImpl.bind(Unknown Source)
at java.net.ServerSocket.bind(Unknown Source)
at java.net.ServerSocket.<init>(Unknown Source)
at javax.net.DefaultServerSocketFactory.createServerSocket(Unknown Source)

at org.apache.commons.net.ftp.FTPClient.listFiles(FTPClient.java:2322)
at FtpTest.main(FtpTest.java:29)
the test code is,
FTPClient client = new FTPClient();
try {
client.connect(Inet6Address.getByName("2010::214:4fff:fe4d:2c4b"), 21);
client.login("abc", "abc");
client.enterLocalActiveMode();
client.setActiveExternalIPAddress("2010::214:4fff:fe4d:2c4b");
FTPFile[] list = client.listFiles();
if(list != null && list.length > 0) {
for(int i=0; i<list.length; i++) {
System.out.println(list[i].getName());
}
}
} catch (SocketException e) {
e.printStackTrace();
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

[jira] Commented: (NET-347) FTPClient.listFiles throw exception

Bogdan Drozdowski commented on NET-347:
---------------------------------------
Is this the code that isn't working? The given code tries to bind to the address of the server. The address to bind to must be one of the local addresses, not a remote address. If not using NAT, don't set the active external IP address or set it to :: (to force IPv6 addressing). If using a NAT, set it to the external address of the gateway.
