This article mainly introduces the use of Pureftpd, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Pureftpd is an open source code software that is used on many kinds of Unix and conforms to the GPL protocol. As its name implies, it is a pure Ftp program. This article teaches you Pureftpd passwords and pure-pw scripts.

Q: I want to create a virtual user with a shell script. If you use pure-pw useradd. It always asks for a new password. Is there a command line option to tell pur-pw the password (similar to useradd ftp-user ftp-password-m)? (atlce)

A: it's not a good idea to give plaintext (or bad one-way encrypted) passwords through the command line option. Because users can use a simple "ps" command to find these passwords.

One way to enter a password (not through the keyboard) is to enter the password twice in a temporary file and then redirect the file to standard output. For example:

Pure-pw useradd john-d / tmp/john-u ftpuser-m < ~ / tmp/passfile

In the file ~ / tmp/passfile, there is something similar to the following:

John's password john's password

If you really want to avoid using temporary files, and no one but you can log on to the computer, you can do the same:

(echo blahblah; echo blahblah) | pure-pw useradd john-d / tmp/john-u ftpuser Thank you for reading this article carefully.
