well we use a firewall to do most of our protection, however have you looked at:
smit user
Reset User's Failed Login Count
then or...
chsec -f /etc/security/lastlog -a "unsuccessful_login_count=0" -s 'kmj'

view /etc/security/lastlog
/kmj
kmj:
time_last_login = 1156789317
tty_last_login = /dev/pts/42
host_last_login = valued-827c7724
unsuccessful_login_count = 5
time_last_unsuccessful_login = 1166039821
tty_last_unsuccessful_login = /dev/pts/16
host_last_unsuccessful_login = user.domain.com

I know this will lock down your telnet users that fail to many times. sorry no ideas on the IP based.

PTS_QUIT(1)						       AFS Command Reference						       PTS_QUIT(1)

NAME
pts_quit - Exit from pts interactive mode SYNOPSIS
pts quit [-cell] <cell name> [-noauth] [-localauth] [-force] pts q [-c] <cell name> [-n] [-l] [-f] DESCRIPTION
The pts quit command exits from pts interactive mode. The command can be run from the command line or interactively, but on the command line it does nothing and is therefore of questionable utility. CAUTIONS
Prior to OpenAFS 1.4.5 and OpenAFS 1.5.23, the pts quit command was only available on Unix or Linux and when OpenAFS was compiled with the supergroups option (disabled by default). As of OpenAFS 1.4.5 and 1.5.23, it is always available. OPTIONS
Although they have no effect, pts quit takes the following standard pts options: -cell <cell name> Names the cell in which to run the command. For more details, see pts(1). -force Enables the command to continue executing as far as possible when errors or other problems occur, rather than halting execution at the first error. -help Prints the online help for this command. All other valid options are ignored. -localauth Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. Do not combine this flag with the -cell or -noauth options. For more details, see pts(1). -noauth Assigns the unprivileged identity anonymous to the issuer. For more details, see pts(1). OUTPUT
This command produces no output. EXAMPLES
Here is an example of a pts interactive session: % pts interactive pts> quit % SEE ALSO
