Python Pysft/paramiko 'EOF During Negotiation' Error

I'm using pysftp to download and upload some files. This exact same code I just run an hour before and was fine, but now I got this 'EOF during negotiation' error. What am I missin

Solution 1:

I got this same error in a program using password authentication. Figured out it was because the password on the SFTP server had expired. Reset it, and everything worked.

Solution 2:

this is how i fixed : "/etc/ssh/sshd_config" i am using the centos and then i saw the this line(#) which was the wrong binary for the sftp for me, then i found the the good one and it's seem's to be working for me:

Subsystem sftp /usr/libexec/openssh/sftp-server
#Subsystem sftp /usr/lib/openssh/sftp-server

for lsb or debian try this :

Subsystem sftp internal-sftp

thank you.

Solution 3:

Turns out this was a connection issue in the SFTP server. Contacted the SFTP admin who fixed it, and now the same code works fine.

Solution 4:

For what it's worth, in my particular case, it was because someone had commented out the SFTP Subsystem in OpenSSH. Read more about how to enable it here: https://serverfault.com/q/660160/453708
