FTP server/client issues
« on: February 04, 2009, 12:44:46 pm »
   

Buffalo Linkstation Mini

LS-WSGL/R1 F/W 1.06
Windows XP/Vista
Forwarding port 0000 to 21 on router. 0000 is a fake port, not posting real one here.
When using Flasfxp or ftprush. I have to set the client to -l or connection will time out when trying to list directory. Transftering files from Linkstation to laptop at work, file transfer stops midway or after file transfer is complete it will not continue to next file in queue. The connection times out and then my client reconnects and continues with next file in queue. This is anoying and time consuming.  I have set up a ftp server at home (Gene6) many times with same port setup and never had any issues. If some one could look into this and fix in future firmware or tell me what settings I should be using in my client. File upload is not affected to my knowledge. Please add implicit ssl ftp to future firmware as well. Stuff like this makes me want to void my warranty and install some other sort of fw or OS.
 
PS i am not a Linux user so please don't suggest linux.
Filezilla for windows will not work for me either. It does not contain option for -l from what I can see.

Can you give me some info about what -l does? I wasn't able to find it in the docs for those ftp clients.

FlashFxp

Site Manager Options tab.

Use 'STAT -L' to list directory.

The alternative that doesn't work, which is checked by default is Use MLSD to list directory.

So like I said the STAT -L works, however when transfering multiple files, the first file in queue will transfer and hang at the end when it should be starting the next file in queue.

 

[R] 227 Entering Passive Mode (00,000,000,0,15,192).
[R] Opening data connection IP: 00.000.000.0 PORT: 4032
[R] RETR 00-the_legion_of_doom-incorporated mp3.sfv
[R] 150 Opening ASCII mode data connection for 00-the_legion_of_doom-incorporated mp3.sfv (902 bytes)
[R] 226 Transfer complete.
Transferred: 00-the_legion_of_doom-incorporated mp3.sfv 912 bytes in 0.00 seconds (0.1 KB/s)
[R] TYPE I
[R] 200 Type set to I
[R] PASV
[R] 227 Entering Passive Mode (00,000,000,0,8,76).
[R] Opening data connection IP: 00.000.000.0 PORT: 2124
[R] RETR 01-the_legion_of_doom-ebola_in_memphis_(every_time_i_die_vs_norma_jean).mp3
[R] 150 Opening BINARY mode data connection for 01-the_legion_of_doom-ebola_in_memphis_(every_time_i_die_vs_norma_jean).mp3 (5750639 bytes)

 

From here it hangs unless i wait and it disconnects and auto reconnects. It then asks me to resume and continues to next file. It downloads the next file and then hangs.

Do you have the same problem trying ftp locally? Use the private address of the Linkstation and port 21.

No locally 192.168.x.xxx:21 workst fine even when using wan IP given to router with port xxxx forwarded to 21. However when I connect to my second router and modem at home I get this same issue that i have at work when using non local ip aka ip from service provider with same ports forwarded. I an use these same ports and Ip with gene6 and flashfxp as client have not one single issue. Let me know if this sounds confusing

Passive ports 50000-50100 open. Not sure what ports this device uses for passive.

In that case it sounds like you may have a confict between the router's firewall (the router the LS is attached to) and the FTP server on the LS. Does that router have an SPI firewall?

   Any one know if the ftp server uses specified passive ports? No options to change, wasn't sure if it was hard coded in or in a config not seen by the gui.
