`cdcc info' with a ``broken'' map on a host with network:
# 05/27/09 14:16:27 CEST /var/dcc/map
# Re-resolve names after 16:04:27 Check RTTs after 14:19:27
# 1 total, 0 working servers
# skipping asking DCC server 62 seconds more
IPv6 on version=3
dcc1.dcc-servers.net,- RTT+1000 ms anon
# undefined name or wrong IP version
dcc2.dcc-servers.net,- RTT+1000 ms anon
# undefined name or wrong IP version
dcc3.dcc-servers.net,- RTT+1000 ms anon
# undefined name or wrong IP version
dcc4.dcc-servers.net,- RTT+1000 ms anon
# undefined name or wrong IP version
dcc5.dcc-servers.net,- RTT+1000 ms anon
# undefined name or wrong IP version
Ok, makes sense. He'll retry on 16:04:27. `cdcc RTT' will trigger the
re-resolve immediately, so I'll run that from somewhere..
Thanks anyway,
