Note that this only uses a local file (defaults to /var/adm/faillog) and has no facility to use LDAP or similar systems to combine results from several machines (or a cluster).
-pam_tally provides similar
functionality to
pam_abl (http://www.hexten.net/pam_abl/).
+pam_tally provides a subset of the
functionality of
pam_abl (http://www.hexten.net/pam_abl/), but where pam_tally simply counts failing usernames, pam_abl allows for:
+
+- counting failing hosts as well as usernames (my logs show the same attacking hostnames trying lots of different usernames rather than the other way round)
+
+- configurable time-based failures (e
.g. record a failure if the user or host fails 5 times in an hour or 10 in a day)
+
+- configurable time-based auto-purging of failure database
+
+On the other hand, pam_abl seems to have 2 issues at the moment:
+1. some users (including me) report failures not being recorded in database (fixed in current CVS from sourceforge)
+2. an issue with OpenSSH where failures don't seem to be recorded (more details here: http://sourceforge.net/tracker/?group_id=148927&atid=773100)
