Change IP addresses considered local by iPlanet Messaging Server tcp_intranet

contributed by qmchenry on November 29, 2004 under UNIX software

If a user does not authenticate during an SMTP session and is connecting from an IP address not considered local, the user will receive a 5.7.1 Relaying not allowed error message. This recipe describes the configuration change to solve this problem.

Using ipfilter to alter nmap OS detection results

contributed by Michilimackinac on February 1, 2004 under IPFilter

nmap is often used to perform OS detection on remote systems if it cannot be determined by other means. It sends tcp packets which have problems and detects how each handles the errors. By tweaking things in ipflter we can trick nmap into thinking it is dealing with some other OS or be less certain about it’s guess. Some additional resource are usually available in the OS sysctl variables (FreeBSD) and ndd settings (solaris) to help control things also.
