Cool SFTP Transfer Issues
I searched previously, and found some others with SFTP issues, and I am now having them. I dont expect a fix, but the devs should know.

I am using
Flashfxp: 4.2.5 (build 1801)
Windows 7x64 sp1

SFTP Win7x64 -> to -> SunOS mkeap58 5.9 Generic_122300-62 sun4u sparc SUNW,Sun-Fire-V240

I connect, and can idle all day.. as soon as I send up files, it moves a few meg of data, then just drops. After a few times, FFXP will just give up and move to the next file. If I move small files <1MB, they move up ok, but some will still drop out. It immediately reconnects and resumes. This is ONLY on upload, download is fine. The bummer of this is, Filezilla works no problem with exact same credentials. Thanks for any guidance. Great program, been using it for YEARS!!!

Hello Matt,

Please try this development build, I have added special tweaks when Sun_SSH is detected and this should improve the compatibility and hopefully resolve the problem you're experiencing

https://oss.azurewebsites.net/testr/dev-builds/ffxp4.2.5.1806.zip

Unzip the flashfxp.exe into your FlashFXP program folder overwriting the existing FlashFXP.exe

I do not have a Sun_SSH SFTP server for testing so my tweaks may or may not be optimal or completely resolve the problems.

Thanks Bigstar!

Sorry I did not test yesterday.. I was not near that system. I transferred up another large file 300+MB.. It did the same thing only once, where it dropped and reconnected. Part way through it, it also slowed down from about 400KB/s to zero, and timed out.. but it reconnected, and went through eventually.

Whatever you changed, it seems to have solved the problem, or reduced the problem significantly. I use this connection on a fairly regular basis, so I will report back if I come up with any other issues.

I appreciate your help and your program immensely. I use it on an almost daily basis, and has been one of the most important programs in my computer career. If nobody has told you thank you yet today, here it is! It is worth every penny, and support like this makes it invaluable!

Thank you for the update.

I have made a few additional changes can you please test this update and let me know if it is better or worse than the previous?
https://oss.azurewebsites.net/testr/dev-builds/ffxp4.2.5.1807.zip

I tweaked my original changes using Sun_SSH_1.2 running on OpenSolaris x86 under VirtualBox and saw increased transfer speeds and improved reliability. I hope you see similar results.
