Dear Mario,
I have the same problem some days ago, try with this:
( echo ${PASSWORD} ; echo ${PASSWORD} ) | pure-pw useradd ${USUARIO} -
u ftpuser -g ftpgroup -d /backup/${USUARIO} -N ${QUOTA} -m > /dev/
null 2>&1
From the FAQ at:
http://pureftpd.sourceforge.net/FAQ
"* Passwords and pure-pw scripting."
====================================================================
-> I would like to create virtual users with a shell-script. if i us
pure-pw useradd ..... it always asks for the new password. is there any
command-line option which tells pure-pw the password (like useradd
ftp-user
ftp-password -m) ? (at1ce) .
Giving cleartext (and badly one-way hashed) passwords through command-
line
switches is a bad idea. Because users could issue a simple 'ps'
command and
discover these passwords.
One way to enter a password (not from the keyboard) is to put the
password
twice in a temporary file, then redirect that file to stdin. Example:
pure-pw useradd john -d /tmp/john -u ftpuser -m < ~/tmp/passfile
And in ~/tmp/passfile, have something like:
john's password
john's password
If you really need to avoid a temporary file and if nobody but you
can log
on the machine, you can always do this:
(echo blahblah; echo blahblah) | pure-pw useradd john -d /tmp/john -u
ftpuser
