 ====================================================== - ............ - PASV - 227 Entering Passive Mode (0,0,0,0,12,1) - Opening data connection IP: 0.0.0.0 PORT: 3073 - Unable connect to 0.0.0.0:3073 (Can't Assign Requested Address(10049)) - ............ ======================================================  why is "227......(0,0,0,0,...,...)"?  there is four zero . the files failed to transfer.  Can someone help me?  Thanks a lot.

I think that you cannot use passive mode.  

 I do not understand the ftp server very well, but I can log into it, and upload to it, but I cannot see files, or download files that I "know" are there.   I wrote a program that ftp's into my linux board, I had to use active mode for it to work correctly. Passive never worked for me.  Good luck.  SmartFTP logs in just fine btw

Now, already run under the passive pattern, as I reading and revised the source code. 

 ftpd.c 1,293 lines ====Original================================================ 1293 printf(" (%d,%d,%d,%d,%d,%d)\r\n", UC(a[0]), 1294 UC(a[1]), UC(a[2]), UC(a[3]), UC(p[0]), UC(p[1])); ========================================================= ====Modified=============================================== 1293 printf(" (%d,%d,%d,%d,%d,%d)\r\n", 1, 1294 2,3,4, UC(p[0]), UC(p[1])); /* if 1.2.3.4 is my IP */ =========================================================  Upload, Download all runs correctly.  so I thought the passive pattern may run, only is any place disposition is not correct.    About is unable the display files question, you should examine the /etc/passwd file . for example :  ===passwd================================================= ....... mail:x:8:12:mail:/var/spool/mail: ftp:x:14:50:FTP User:/mnt/cf: nobody:x:99:99:Nobody:/: ....... ========================================================= you should copy it as : /mnt/cf/bin/ls  when I run the ftp for the first time , I also cant see any files http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/happy.gif .  and if the passive not worded , you&#39;d better check the DNS&#39;s setting , maybe it not correct .    My English is not good, please forgives . Thanks for your reply.
