Hi All,
Paul, I did exactly that, and then tried running ./rc.local from the
terminal, but got a permission denied. When you say "initscript", do
you mean the snort.conf file or the /etc/rc.d/rc.local which contains
the following,
[root@localhost rc.d]# cat rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
/usr/local/bin/snort -c /etc/snort/snort.conf -i eth0 -g snort
I got the following when starting manually,
[root@localhost ~]# snort -cs -i eth0
Running in IDS mode

Hi All,
Paul, I can start snort with just typing snort, though, and get the
following output,
[root@localhost snort]# snort

With a continually blinking cursor here....I'm assuming that that is the
desired result. Still don't un why the boot hangs, though. Cheers.
