Depending on the flavor of the system and its configuration, adding
lines to /etc/hosts can be effective for working around local or
remote DNS problems.

A local copy of gdb is not required to create a core dump,
although I understand that some versions of gdb can be used.
I use `kill -6` or another fatal signal.
Some systems disable by default the creation of core files. This
irritating, simplistic misconfiguration (that's only my view) is
especially common in the Linux world. See
Gdb would have been handy for looking at named without creating a
core file or disturbing the process by more than what it would see
as a jump in time.
