Problem with radzap

[Andoni Ayala - KNET]

hello!.

I have experienced with freeradius, but i updated to 1.0.1 on Fedora
Core 3 and when i use radzap i get this error:

Error: There appears to be another RADIUS server running on the
authentication port 1812

i launch this command:

radzap '' 34 user456

even, replacing '' with NAS ip.

can anyone help me? (i'm searching on google and freeradius-list archive
but nothing help me)
Thanks
