Normally the kernel should recognize it as local and route the packets over lo. Clone ip, interesting nat/forwarding rules, bridging setups, etc. may not fall under "normally" -- I expect running tcpdump on the interface with src and dst hosts set to local and cluster ips resp. and pinging the cluster ip will tell. (This is also why an RA can't test if a daemon's answering on a public ip, where you actually care about it. The best it can do is see if it's answering where you don't care: on lo.) -- Dimitri Maziuk Programmer/sysadmin BioMagResBank, UW-Madison -- http://www.bmrb.wisc.edu
