This file describes how to enable snoopy after installing this snoopy RPM on a Fedora on Redhat/CentOS system. snoopy can be enabled in one of two ways: 1) To enable for the whole system with a global preload. echo "/\$LIB/snoopy.so" >> /etc/ld.so.preload 2) To enable in user space for a particular user then run one of these depeneding upon your shell. export LD_PRELOAD=/\$LIB/snoopy.so #for sh/bash/ksh/zsh setenv LD_PRELOAD /\$LIB/snoopy.so #for csh/tcsh Note the '$LIB' in these lines is not meant to evaluated at configuration time. It is instead evaluated at runtime. That is is to say the /etc/ld.so.preload should look like this with the variable in after configuration. # cat /etc/ld.so.preload /$LIB/snoopy.so Afterwards logs will be made via syslog to /var/log/secure
