By default RH uses IPv6 (Windows uses IPv4). Most DSL and cable companies only support IPv4... After using parameters mentioned previously to force Java to use either IPv6 or IPv4, I came to the theory that the problem is probably either in Sun's or RH's implementation of IPv4 on Linux.

George,
I still think this is a class loading problem.
I can reproduce the problem on Win2k+3 and Suse 9.2,
doing the following:
java -cp .;commons-net-1.4.0.jar; Test // fails
java -cp .;commons-net-1.4.0.jar;jakarta-oro-2.0.8.jar Test //works
Please try to run the snippet below.

import java.io.*;
// try to execute with:
// java -cp .;commons-net-1.4.0.jar;jakarta-oro-2.0.8.jar Test
public class Test {
// dummy has really no function other than to test if the oro lib is in the
class path
MalformedPatternException dummy=new MalformedPatternException();
public static void main(String[] args) {
Test test=new Test();// construction should fail if oro lib is not in
the class path
FTPClient ftp = new FTPClient();
try {
ftp.connect(konsensys.com);
ftp.login([EMAIL PROTECTED], errorlog);
String[] files = ftp.listNames();
for (int i = 0; i files.length; i++)
System.out.println(files[i]);
}

}
}
}

I would appreciate it if people who are not committers on this project would refrain from changing the status of bugs, especially when they obviously haven't bothered to read the voluminous traffic that this still unsolved bug has generated. If you had, you'd have noticed that the problem was seen with listNames() as well as listFiles(). Go ahead and try it with listNames(). It will run like a champ for you on Windows, even without Oro. The bug was about the program hanging, not about errors being thrown. As for the java.lang.NoClassDefFoundError, I'll just say that the classpath requirements for this package are well documented. It's true that you can run methods other than listFiles() without hitting the problem, because the listFiles system is the only part of the system that makes use of Oro. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The PORT command from the trace looks fine. I think we can rule out IPv6 issues. It's almost definitely a local configuration issue. The thing to do would be to capture a trace of the FTP protocol traffic (just the FTP commands going back and forth) for the native ftp command (which apparently works) and for the failed FTPClient and compare the two (have both of them perform exactly the same transaction). -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

some results here that didn't seem to show up. So, I'll post again. As per a

I believe the above indicates the firewalls are disabled. I disabled them via
the wizard when installing the Linux OS (couldn't find a firewall tool).

Get this jar onto your classpath and see what results. It would appear to me that you certainly do have your firewalls disabled. I am waiting to see what suggestions Daniel Savarese (see comment 25) may have since he suspects an IP v.6 cause. I think his diagnosis is likely, but I have no real knowledge. Is it possible to turn IP6 support off when executing programs or do you have to build a kernel with it disabled? If you can turn it off without too much trouble, this might provide useful diagnostic information. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I've had Java programs suddenly break after upgrading to the 2.6 Linux kernel with IPv6 enabled (like Fedora Core 3). Sometimes the fault lies with the program, sometimes with the way the Sun JDK implementation treats IPv4 and IPv6 addresses, sometimes with a server that isn't binding new sockets to IPv4 interfaces= . I'm out of town right now with limited net access, but if the problem hasn't been isolated by the time I return, I'll run some tests on my home network. I haven't fully absorbed all of the issue report entries, so I may be totally off the mark. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

ANY REPLY MADE TO THIS MESSAGE WILL NOT BE COLLECTED AND· INSERTED IN THE BUG DATABASE. http://issues.apache.org/bugzilla/show_bug.cgi?id=35338 --- Additional Comments From [EMAIL PROTECTED] 2005-06-22 09:26 --- OS: Fedora Core 3 (kernel: 2.6.11-1.27_FC3), with all the latest updates (hoping some update might fix the problem). The miniprogram was compiled and run with both Java 1.5.0_03 and 1.4.2_08 (both hang). I don't have Eclipse installed there (been doing the development on Windows and testing on Linux. I did insert print statements immediately before and after listNames() and only the print statement before the call appeared. I think the odd looking IP address is dynamically assigned by the router between the OS and the network. The Windows XP uses the same router and the miniprogram runs fine. So, I doubt that is the issue. A partial printout of the tcpdump/tetherial is below.

Why doesn't he have a problem ftp-ing to the same site with his command-line ftp application? A tcpdump of that for comparison purposes would be very useful. For sure a tcpdump would really help. Maybe only ports above 1024 are blocked and this command-line utility uses one below? JFYI: SuSE knows a configuration in its firewall configuration for this FW_ALLOW_INCOMING_HIGHPORTS_TCP=yes|no|... And yes, I know modern firewalls with connection tracking are able to open those ports dynamically (ip_conntrack_ftp). Said that I found there was a problem with fedora in this area: http://www.opensubscriber.com/message/[EMAIL PROTECTED]/1466926.html Maybe its sufficient to load this module: /sbin/modprobe ip_conntrack_ftp 2. Is the problem solely a problem with listNames()? Perhaps a simple program using listFiles() would fail similarly. That would tell us something. I dont think so. I tried the code from comment #0 on my linux box and it worked against his server. This and the unwanted ICMP reply make me strongly think that it is NOT a commons-net fault. 3. I believe that somewhere up the thread George said he'd disabled the firewall. I don't know how that fits into this scenario. Maybe he didn't completely disable it, or maybe there are more than one firewall on the system? Yes, I think he should try the following again *) disable the firewall again *) use iptables -L (on the client system) - there should be no rule active. If there are entries if you see some rules try to delete them using iptables -D INPUT 6 replace INPUT and 6 by the corresponding chain and rule number. *) start tcpdump *) try commons-net ftp again If this works - try: *) restart your system (so the firewall might be up again) *) /sbin/modprobe ip_conntrack_ftp *) start tcpdump *) try commons-net ftp again Its hard to tell what to try through bugzilla, so sorry if this is too much information at once. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Very odd. The oddest thing about it is it looks to me that the command initiated by the listNames() method (NLST) appears to have succeeded and been acknowledged. So why the hang? Do you have a debugger you can run this under (such as the one in Eclipse?)? Setting a breakpoint on the line where you are looping through the array of names and returned, do you hit that breakpoint? The other thing I notice that strikes me as odd is line 16. We issued no port command, unless that somehow happens when in passive mode, if that code is still in your program. 16 0.652929 192.168.195.128 - 209.18.78.251 FTP Request: PORT 192,168,195,128,128,88 What does it mean 192,168,195,128,128,88? I suppose you could try disconnecting from the FTP server before entering that loop to see if that does any good, but I admit, I'm grasping at straws here. However, tcpdump as you started it (I know I told you so :-) captures only what happens on port 21, due to the nature of ftp the data connection uses a different port. So please, do the following tcpdump -w ftplog.dmp host konsensys.com But please be sure no other network connection is active from your box to this host. Afterwards we have logged the full communication which happens between you and the ftp server. Now we should see the transfer of the directory listing. I agree. In light of this PORT command, it would be interesting to see what is going on here. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

We now have two users with the problem. I don't know much about Conectiva, but some googling tells me it's a Brazilian distribution. I don't know Portuguese but it seems to be using Kernel 2.6.5. Is that right in your case? Say George, looking back over this whole thread, I don't think we asked you what kernel your Fedora was using, Could you tell us. Maybe this is the common element here. Another question I want to ask is this: Is the problem with listFiles() only or do you see it with other commons-net APIs? like listNames() for example. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Then run your program and examine its output. You might want to also ask this in the Fedora lists. Someone there may know something about the bleeding edge changes they are doing.

Further, I can access the directory with the same host, username, and password as the miniprogram using ftp at the command line. I think that if one could access with same host, username and password from the command line ftp, that it is more likely a problem with how commons-net.jar is interfacing with the native code. And being as it seems to work for you on RHEL, it is most likely a problem with some of those bleeding edge changes to the kernel or networking that Red Hat likes to put into the Fedora version. I don't know much about networking, so it'll take me a little while to learn how to use etherial.

The following complet miniprogram demonstrates the problem (correctly lists
the two files Test.class and Test.java on when run on Windows XP but hangs
on when run Fedora Red Hat Linux):
import org.apache.commons.net.ftp.*;
import java.net.*;
import java.io.*;

public static void main (String[] args) {
FTPClient ftp = new FTPClient();

As expected, it works there. OK, so what is it about your environment? Can you send a full java version, just run java -version and send the output. Just a thought. Did you build commons-net from scratch in your jdk 1.5 environment or did you just download the binary? I don't know if that would make a difference but I suppose it's possible? You snet me the full OS of the server, but that isn't really relevant. FTP pretty well sits on top of the OS and doesn't care what OS is talking to it.
