It has been behaving more 'standard' way before. Self installing krb4 or heimdal from kth seems provides better rcp. o How does the firewall treat backward connections ? (Ipfilter proxy ?) Depending on it, ports may not be properly 'diffused' (this again might be due to 'odd' rcp, though). As far as I can tell, rcp with said makes on both ends over ipfilter with r-* proxy works well (not very well, unfortunately). Closely watching FreeBSD's rcp behaviors at the connections would reveal something more. horio shoichi
