and I re-do this
service vsftpd start

But I still got attached error.

What are you using on the client side to make that connection?
Are you before attempting the upload?

I can connect to your server anonymously, but can't upload either. You must not have the permissions set correctly on the pub folder. What are they?

Hi Scasey,
Can I have more details to adjust privileges of pub folder, like to create proper user account for accessing it?

You need to change permissions to allow anyone to write to the directory but please do not allow anonymous login or writing on a public ftp server.

You need to configure ssl/tls. In addition you need to use a ftp client that has ssl capability like lftp or a GUI like filezilla.

Guys, from post #26, where the OP said:
(bolded parts for emphasis)

This is much like the OP's MANY other threads; what little you can drag out is contradicted or confusing. He's saying he wants SFTP now, but for some other-worldly reason, thinks making changes to the vsftpd configuration will help.

Perhaps, if you were to post some details of what you have set up now. We're not mind readers. We can't tell you what's wrong if you won't show us what you've done.

Yeah. Don't disagree with your observation at all. He did switch from ftp to sftp and back again...<sigh>

Although the OP posted sftp I think it was in error and actually used ftp. I can use sftp:// in the Windows file browser but it is associated with WinSCP because that is what that particular computer has installed otherwise an error message should be displayed. pub is the ftp default anonymous directory.

Another point: The OP says they configured an "sftp user" with /sbin/nologin shell. With that shell, the user can't login at all, in my experience. That shell works to allow ftp access only to a user, but sftp won't work.

Still, until the OP decides to tell us what he's actually doing and how he's configured his ftpd server, I'm reluctant to try to help futher.

I use /sbin/nologin with OpenSSH's sftp server. It works fine.

Interesting. Doesn't work for me...
OH!, I've set some AllowUsers in sshd.config The user I tested with wasn't one of those. Doh!

Yes, below line is un-remarked, within file /etc/vsftpd/vsftpd.conf.

and I re-start this
service vsftpd start

I can access

sftp://113.255.219.215/

How to create user account to be able to write SFTP folder?

Hi Huamin,

You have been told several times that SFTP (really SSH) and FTP are not related, at all.
There is not configuration you can do on vsftpd that will affect sshd.

Make a clear choice: SFTP or FTP?
Then let's us know what error you get (if any).
Also, share details regarding the client you are using to access the server.

Good luck; third page of posts now, along with repeatedly asking. Please see the OP's posting history, as this is a common theme.

Huamin, unless you're going to actually post a clear question with the relevant details, why bother posting? No one is going to be able to help you without details and a clear question/goal. You were told, point blank, to not use FTP because of security concerns, and you were even handed ways of getting SFTP to allow 'anonymous' connections, but you don't even acknowledge them. You were asked questions which you don't answer. So what's the point?

Tshikose,
I need SFTP.

I only use Windows file explorer to access the following.

sftp://113.255.219.215/
