Guys this is an error I am getting when I try sending files to a server. I am not sure what went wrong. Can anyone help me fix this? Thanks in advance.

$ rsync -avz ./ ssc:/webapp/

i add "-e /usr/bin/ssh" and it fixed the issue.

rsync -e /usr/bin/ssh -vP /c/projects/cpp/RecFileExtractBatch/example_recfile_extract_command_file.xml thtran@p811:/home/thtran/mnt_win_pdatx_linux

Answer 2

I'm using cygwin rsync on Windows 11. I'm still not 100% sure why this only started failing for me recently, but I found that using Windows OpenSSH with cygwin rsync was causing the error.

I wound up installing OpenSSH for cygwin and moved C:\cygwin\bin before C:\WINDOWS\System32\OpenSSH\ in my Path in Environment Variables. That fixed it for me.

GentlemanJohn's answer was extremely helpful for me. I took his advice but I used /user/bin/ssh instead of revising my path. As in:

$ rsync -avz -e "/bin/ssh -i .ssh/id_rsa" --progress [email protected]:/ads/qsmrp/ qsmrp

(The trailing slash on the qsmrp directory indicates copy its content only.)

The Windows version of openssh prevented rsync from working (0 bytes transferred).

Remove OpenSSH-Cliente on ''Settings' > 'Apps' > 'Optional Features', install Git and add C:\Program Files\Git\usr\bin to Windows PATH. and ensure then rsync and ssh have the same paths, use 'where ssh' and 'where rsync' to check that.
