Andrew,  

What version of iptables are you using?  What options are you using to start 
portsentry (-tcp, -atcp, etc...)?  

For the firewall configuration, check your PATH to iptables.  I would also 
recommend changing the "-I" to "-A".  The "-I" command needs a number to 
specify where in the ruleset you want the rule to be placed (i.e., 
"/sbin/iptables -I INPUT 5 -s $TARGET$ -j DROP" would insert this rule at the 
5th position).  

For your TCP_Wrappers issue, are you getting any errors in the message log for 
this?  Have you tried scanning your system using another tool, like nmap?  

Just throwing some ideas out there for you.

Hi everyone

I am trying to set up portsentry on redhat enterprise AS.  I compiled
the source correctly and edited the configuration file according to the
directions.  The program starts fine but when I do a port scan on the
machine with languard it doesn't place the ip address of my machine into
the host.deny file nor does it block it through ip tables.  This worked
fine with redhat 7.3 but I isn't working with redhat enterprise edition.
The version of portsentry I tried is version 1.1 and 1.2 .  The kernel
version is 2.4.21-15.0.4.ELsmp
