If you have setup sftp in chrooted mode and you are unable to log into the server
$ sftp [email protected]
sftpuser[email protected]’s password:
Connection to abcd.com closed by remote host.
Couldn’t read packet: Connection reset by peer
have a look at the /var/log/secure log and if you find the below error
sshd: fatal: bad ownership or modes for chroot directory component “/var/www/vhosts/abcd.com/httpdocs/”
Fix is as below
# chmod 755 /var/www/vhosts/abcd.com/httpdocs/
# chown root:root /var/www/vhosts/abcd.com/httpdocs/
Ensure that the entire path from / to /var/www/vhosts/abcd.com/httpdocs/ have ownership of root user and is not writable by group or any other user. This is certainly one of the limitations of chrooted sftp.
