Package: proftpd-basic
Version: 1.3.6-4
I think there is something wrong with the sftp module in buster
because proftpd cant read ssh Host keys
i also tried to recreate the keys with dpkg-reconfigure openssh-server
or manually by ssh-keygen -t rsa -b 4096 -f /etc/ssh/ssh_host_rsa_key
and i tried to create keys on a Debian 9 machine and copied them on the
Debian 10 machine.
so i think it isn't the key its the module.
How to reproduce
Install Debian 10 minimal
apt install proftpd-basic
create minimal sftp config
echo '<VirtualHost 192.168.1.15>
DefaultRoot ~
RequireValidShell off
SFTPEngine on
Port 2222
SFTPLog /var/log/proftpd/sftp.log
SFTPHostKey /etc/ssh/ssh_host_rsa_key
SFTPAuthMethods publickey keyboard-interactive
#SFTPAuthorizedUserKeys file:/etc/proftpd/authorized_keys/%u
# Enable compression
SFTPCompression delayed
</VirtualHost>' > /etc/proftpd/conf.d/sftp.conf
Restart Service
systemctl restart proftpd
get broken service
root@proftpd-test:/etc/proftpd/conf.d# systemctl status proftpd
