The situation was 1 a server was moved from one location to another and the static route to that server updated in the networks default router (a Cisco with no known vices in this regard) 2 the relocated server was, after some 30 minutes in the new location, restored to its former connection because the the move revealed that futher work was necessary to relocate it 3 Thereafter, vital boxes such as the DNS (FreeBSD-2.2.8-STABLE) could not contact the moved server. Ping from these boxes reported "sendto: no route to host". There were . about 3 hosts - all of which are usually in constant communication with the relocated server - that could no longer contact the server. The OS range from FreeBSD 2.2.2-STABLE to 2.2.8-STABLE. . no obvious problems revealed by netstat -rn. This display showed - the same default gateway as before the move, with the G, U, S and no M flags - no host routes to the server I expected that after the relocation the default router would redirect the hosts to use a new router to access the server. The problem was finally worked around by rebooting the three servers. Perhaps I should have tried netstat -flush from the console ?
