Hi ,
I am trying upload/download a file of size 255 chars. I see scp
download/upload successful upto filename size of 246 chars.

Beyond 246 chars :
*upload : timeout happens*
*download : fails with error "curl: (78) Unterminated response from SCP
server"*

*upload:*
# curl -T test.txt scp://135.249.31.90/home/test/

*123456789981788393912345678123456789981788393912345678998178839391234567899817883939134567899817883939123456789981788393912345678998178839391234567899817883939998178839391234567899817883939123456789981788393967899817883912345678912345678912345.txt*
