All the machines in these cases have been running Solaris on SPARC hardware. And as I indicated, I tried Fedora 10 off of a USB and it works too. And Ubuntu 7.10 works too. I am attaching tcpdump collected on eth0 and eth1 interfaces since you wanted to see ICMP requests coming in one interface and ICMP replies going out the other collected on 7.10. - Venkat -------------- next part -------------- An HTML attachment was scrubbed...
