2.33. LockoutCommand *global*
The name of a command (as it would be entered from the shell) that will lock out the host IP of an offending system. The IP address will be substituted for the first occurrence of the string %s. This will be executed with the user ID that Interchange runs under, so any commands that require root access will have to be wrapped with an SUID program.
On Linux, a host may be locked out with:
ipfwadm -I -i deny -S %s
This would require root permissions, however, under normal circumstances. Use sudo or another method to wrap and allow the command.
A script can be written which modifies an appropriate access control file, such as .htaccess for your CGI directory, to do another level of lockout. A simple command line containing perl -0777 -npi -e 's/deny/deny from %s\ndeny/' /home/me/cgi-bin/.htaccess would work as well (remember, the %s will become the IP address of the offending user).
