I'm using Ubuntu, and FTP works in Filezilla, but when I try to use the ftp program, I could log in but the file transfers are often stalled (and fail with timeout), except sometimes when the file is very small.
I heard something about "passive" and "active" transfer but I'm not sure if it could make a difference.
What is the likely setting that would allow the ftp program to work? Or else why would Filezilla work but not ftp?
filezilla authomaticaly switches p/a mode, but using ftp you sould explicitly set the mode. Here is good explanation of a/p difference on stackpverflow What is the difference between active and passive FTP?
