update-rc.d – debian
Insert links using the defaults:
update-rc.d foobar defaults
Equivalent command using explicit argument sets:
update-rc.d foobar start 20 2 3 4 5 . stop 20 0 1 6 .
Insert links for a service that should be running during multi-user
mode, but that does not need to be explicitly stopped on shutdown:
update-rc.d foobar multiuser
Equivalent command using explicit argument sets:
update-rc.d foobar start 20 2 3 4 5 . stop 20 1 .
More typical command using explicit argument sets:
update-rc.d foobar start 30 2 3 4 5 . stop 70 0 1 6 .
Remove all links for a script (assuming foobar has been deleted
already):
update-rc.d foobar remove
Example of disabling a service:
update-rc.d -f foobar remove
update-rc.d foobar stop 20 2 3 4 5 .
Example of a command for installing a system initialization-and-
shutdown script:
update-rc.d foobar start 45 S . start 31 0 6 .
Example of a command for disabling a system initialization-and-shutdown
script:
update-rc.d -f foobar remove
update-rc.d foobar stop 45 S .

apt-spy – debian
Apt-spy is a program used to test a series of Debian’s mirrors for bandwidth. Apt-spy will then generate a /etc/apt/sources.list file with the fasted server. You can select which of the Debian server’s to benchmark by geographical location.
