I need to setup an FTP server and SFTP server on EC2 supporting both password and cert logins. I just used the stock RHEL and Amazon AMI’s and I can’t login to either.
$ sudo yum install vsftpd $ sudo adduser someuser $ sudo passwd someuser #edit /etc/ssh/sshd_config PasswordAuthentication yes #Comment out this line on /etc/pam.d/vsftpd for good measure, read about it elsewhere #auth required pam_listfile.so item=user sense=deny file=/etc/vsftpd/ftpusers onerr=succeed $ sudo systemctl start vsftpd
My vsftpd conf is as follows
#edit /etc/vsftpd/vsftpd.conf to disable anon login anonymous_enable=NO local_enable=YES write_enable=YES local_umask=022 dirmessage_enable=YES xferlog_enable=YES connect_from_port_20=YES xferlog_std_format=YES listen=NO listen_ipv6=YES pam_service_name=vsftpd userlist_enable=YES tcp_wrappers=YES
I do all this, then attempt connecting from another host. SFTP hangs with the error below and I have to Ctrl+C to get sftp to exit.
$ sftp -v -P 21 someuser@ec2host ... debug1: ssh_exchange_identification: 530 Please login with USER and PASS.
I expect to be prompted for a password and see the users directory! Note: sftp works against port 22 with the regular sshd install. Any idea what I’m doing wrong?
Despite its name
sftp has absolutely nothing to do with FTP. It does not speak the same protocol. It is an ssh client which transfers files over an ssh connection, not an FTP client. SFTP cannot be used to connect to FTP servers.
