Steve,
I followed your sugestion on both tests, the one I try to list and the one
intended to upload a file but both showed different behaviors.
When I run this test:
@Test
public void testPerformanceFtpRiscf80Interno() throws Exception {
FTPClient client = new FTPClient();
try {
client.connect(SOME_AIX_HOST);
System.out.println(client.getReplyString());
if(client.login(SOME_USER, SOME_PASS)) {
System.out.println(client.getReplyString());
client.pwd();
System.out.println(client.getReplyString());
client.enterLocalPassiveMode();
System.out.println(client.getReplyString());
client.list(); // <-- Still generates the 425 reply code
System.out.println(client.getReplyString());
}
} finally {
client.logout();
client.disconnect();
}
}
I still get the same MalformedServerReplyException (Server Reply: : A remote
host refused an attempted connect operation.) on client.logout() method and
got the following server replies:
220 riscf80 FTP server (Version 4.2 Fri May 2 12:48:10 CDT 2008) ready.
230-Last unsuccessful login: Fri Apr 23 18:06:21 GRNLNDST 2010 on /dev/pts/4
from SOME_HOME
230-Last login: Fri Apr 23 18:42:58 GRNLNDST 2010 on ftp from SOME_HOME
230 User SOME_USER logged in.
257 "/riscf80/some/path" is current directory.
425 No data connection
But when I changed the test method intended to upload a file I got very
different results, the test succeeded and the file was transferred to the
host like the code extract below shows. It's interesting to notice I removed
the preferIPv4Stack property.
...
fis = new FileInputStream(file);
ftp.enterLocalPassiveMode();
ftp.storeFile(fileName, fis);
...
Printing some output I got the following results:
IPv4: null
220 riscf80 FTP server (Version 4.2 Fri May 2 12:48:10 CDT 2008) ready.
230-Last unsuccessful login: Fri Apr 23 18:06:21 GRNLNDST 2010 on /dev/pts/4
from SOME_HOME
230-Last login: Fri Apr 23 18:52:39 GRNLNDST 2010 on ftp from SOME_HOME
230 User SOME_USER logged in.
250 CWD command successful.
226 Transfer complete.
221 Goodbye.
I also tried the FTPClient#listNames high level method and that worked fine
using local passive mode.
Thanks
