Are you specifying the proper port when attempting to connect?

if you mean port 98 like localhost:98, yes!

I think there was a mistake made when the service was added to the /etc/services
file.  Try 99 for now.  The version in the build tree has the erroneous line
fixed.

I have is the same problems,  when try http://myhost:99/ 
recive error the connection
in linuxconf - misc - linuxconf network access
add my network  and localhost
edit file /etc/xinetd.d/linuxconf-web
change the disable = yes by "no"

try againg I am recive is the same error
not connect
try againg with http://127.0.0.1:99/
recive is the same error , not connect
help me please  my name is Jesus Delgado email- jds

Linuxconf doesn't yet know how to configure xinetd.  Go into ntsysv and toggle
the "linuxconf-web" service on (the "linuxconf" service enables the boot-time
hooks), then run "/sbin/service xinetd reload" to get xinetd to reload its
configuration information.

I have found that the linuxconf web interface is not stable.  It will stop
responding.  xinetd has to be restarted periodically.  I have this problem on
several machines with RH7.0 installed.  It worked better on the 6.9.5 beta.
