A minor point, but is not the cause of your problems, libax25 current 
version is 0.0.10 <http://sourceforge.net/projects/ax25/>.

Because you are having problems via the loopback interface (localhost),
I believe the issue is with your Linux system, not an amateur radio
specific problem.

Is ipchains or iptables/netfilter being used for a firewall?
Is tcpwrapper (/etc/hosts.allow /etc/hosts.deny) an issue?
Are you using inetd or xinetd? 

Do you see the TCP ports you are trying to use when you do a
	netstat --ip -a | grep LISTEN
?

Other useful tools may be 'lsof' and 'nmap -sS localhost' 
'nmap -sT localhost'.

Can you run /usr/sbin/node as a normal user (ignore error message
about unable to open/write to log file)?

Did you try the same with your inetd/xinetd command entries for clx?
(something like /usr/local/clx/bin/clxd)

Simple but embarrassing are still easier to fix. :-)
