[CentOS] PAM and vsftpd

[RobertH]

i have been researching for alternatives.

it is latest centos 4 (4.7) and uses vsftpd 2.01

started (again) investigating possible PAM or PAM module way...

Q: is there a PAM way to control repeated crack retires on vsftpd?

possibly something that can be done in /etc/pam.d/vsftpd

i have been looking for a solution other than fail2ban and/or similar
methods using hosts.allow and hosts.deny or iptables

specifically, i am trying to stop repeated access to vsftpd after more than
x attempts from the same ip address....

thanks in advance for any pointers..
