Debian

CentOS

ansible centosbox -m yum -a 'name=* state=latest'

Debian

ansible debianbox -m apt -a 'update_cache=yes name=* state=latest'

So the OSSEC installer has a conditional expression that doesn't seem to be supported with the version of Bash in Debian Squeeze.

Error:

3- Configuring the OSSEC HIDS.

./install.sh: 158: [[: not found

Fix, update line 372 on install.sh to the following:

if [ "X${USER_AGENT_SERVER_IP}" = "X" -a "X${USER_AGENT_SERVER_NAME}" = "X" ]; then

This was so frustrating, and it appears to be known issue. Unless I'm mistaken double brackets are only used in Bash to do a regular expression conditions, at least that's the only time I've used them...

UPDATE: I also ran into this same issue on FreeBSD 9 and Ubuntu Server 12.04 LTS.
