I downloaded the latest free version of Flashfxp from softpedia.com to test out. I setup my client to connect to my friend's work server, but have found constant disconnects, all happening at 2:10 of the connection (idle). I downloaded Filezilla, setup, connected, and can transfer with no issues, so I'm not sure if I've not got a setting right or something on Flashfxp. I was hoping someone could help me figure this out. I've taken out ip info for security... It always drops the connection on transfer at 2 min 10 sec of "idle" time.. Duration time can be different, but I notice the connection lost time of 2:10 always the same...

try to enable 'send noop during transfer' option.

I sent you a private message with modified build of FlashFXP that uses a lower internal tcp/ip keep alive interval, this should resolve the problem, please let me know.

Hi, thank you for the replies. The send NOOP does nothing, still drops at 2:10 idle time during transfer. I got the PM, and will install the file, and test tonight, thank you! I'll post my results!

So I setup the exe in the same folder overwriting the flashfxp.exe file. I went into Site Manager and verified NOOPS was not checked, and logged in. Tried to transfer a 1GB file. It went past the 2:10 mark that I was having issues with, BUT, disconnected at 3:11

[R] Transfer Failed!
[R] Connection lost: Server (Duration: 4 minutes 24 seconds / Idle: 3 minutes 11 seconds)

Deleted the transfer, and tried again, and it fails at the same time, 3:11
Went into Site Manger, checked send NOOP during transfer, connected, tried again. I may be wrong, but shouldn't I see NOOP in the log as the transfer goes, cause I didn't, and it disconnected again at 3:11

So closed it all out, opened up FileZilla, ALL DEFAULT options on the program, I changed nothing on install other then input of server info. Connected, tried the same 1GB file, downloads, no disconnects.

Since the server is running vsftpd, I thought maybe it was the server software, so I asked a few people that I work with to test with Flashfxp, and they too got the same problem. So does this mean Flashfxp is not compatible with vsftpd? the change made to the tcp/ip keep alive interval did push it beyond the mark of 2:10 I was having at first, but as noted, only by a minute. So what is different from Filezilla and it's setup, that won't drop the connection on transfer, to Flashfxp's? Thanks again for the help!!
