Set the auth.info facility.level in /etc/syslog.conf and point it to a log (/var/log/authlog for example). Ensure the log file exists. Restart syslog and attempt the log in.
Hi,
I notice in my Sun Solaris 8 sparc workstation, if I failed my login in the 5th time, I will be closed the connection from the host.
I want to make 3 times. That is, if user fails to login with 3 attempts, he will be closed the connection.
How to do it? Of course I am the admin of the... (2 Replies)
Hi. I would like to be able to deny IP address for too many failed login attemps (either from ssh, sftp, ftp, etc). The system I wish this to work on is an AIX 5.1 system. I'm new to AIX but I'm a linux user. There is a program for linux called fail2ban which reads from the log files and see if... (1 Reply)
Does anyone have a good script / cron job that handles this?
I have looked in smit and see it is clearing this count with:

Hi there,
In Solaris 8.
I have accidentally set the eeprom security-mode=command because I followed the CIS benchmark guideline. Initally, it was eeprom security-mode=none. I have tried to login with the correct password numerous time and it still say permission denied.
I have tried to login... (4 Replies)
The purpose of this thread is for everyone to follow the same methodology so we can create a future table, for the benefit of all, that shows how many failed login attempts (hacking) per day per server (and per minute) are happening.

system-auth-ac
SYSTEM-AUTH-AC(5) File Formats Manual SYSTEM-AUTH-AC(5)NAME
system-auth-ac, password-auth-ac, smartcard-auth-ac, fingerprint-auth-ac, postlogin-ac - Common configuration files for PAMified services
written by authconfig(8)SYNOPSIS
/etc/pam.d/system-auth-ac
DESCRIPTION
The purpose of this configuration file is to provide common configuration file for all applications and service daemons calling PAM
library.
The system-auth configuration file is included from all individual service configuration files with the help of the include directive. When
authconfig(8) writes the system PAM configuration file it replaces the default system-auth file with a symlink pointing to system-auth-ac
and writes the configuration to this file. The symlink is not changed on subsequent configuration changes even if it points elsewhere. This
allows system administrators to override the configuration written by authconfig.
The authconfig now writes the authentication modules also into additional PAM configuration files /etc/pam.d/password-auth-ac,
/etc/pam.d/smartcard-auth-ac, and /etc/pam.d/fingerprint-auth-ac. These configuration files contain only modules which perform authentica-
tion with the respective kinds of authentication tokens. For example /etc/pam.d/smartcard-auth[-ac] will not contain pam_unix and pam_ldap
modules and /etc/pam.d/password-auth[-ac] will not contain pam_pkcs11 and pam_fprintd modules.
The file /etc/pam.d/postlogin-ac contains common services to be invoked after login. An example can be a module that encrypts an user's
filesystem or user's keyring and is decrypted by his password.
The PAM configuration files of services which are accessed by remote connections such as sshd or ftpd now include the /etc/pam.d/password-
auth configuration file instead of /etc/pam.d/system-auth.
EXAMPLE
Configure system to use pam_tally2 for configuration of maximum number of failed logins. Also call pam_access to verify if access is
allowed.
Make system-auth symlink point to system-auth-local which contains:
auth requisite pam_access.so
auth requisite pam_tally2.so deny=3 lock_time=30
unlock_time=3600
auth include system-auth-ac
account required pam_tally2.so
account include system-auth-ac
password include system-auth-ac
session include system-auth-ac

None known.
