ubuntu : starting sshd at boot

  • ssh server installed but not starting at boot (I certainly messed up something):

    $ ls -l /etc/init.d/*ssh*
    -rwxr-xr-x 1 root root 3704 2010-09-14 19:20 /etc/init.d/ssh
    $ ls -l /etc/rc2.d/*ssh*
    ls: cannot access /etc/rc2.d/*ssh*: No such file or directory
    $ ls -l /etc/rc1.d/*ssh*
  • a solution is to use update-rc.d:

    usage: update-rc.d [-n] [-f] <basename> remove
           update-rc.d [-n] <basename> defaults [NN | SS KK]
           update-rc.d [-n] <basename> start|stop NN runlvl [runlvl] [...] .
           update-rc.d [-n] <basename> disable|enable [S|2|3|4|5]
                    -n: not really
                    -f: force
    The disable|enable API is not stable and might change in the future.
  • by issuing :

    $ sudo update-rc.d ssh defaults
    update-rc.d: warning: ssh stop runlevel arguments (0 1 6) do not match LSB Default-Stop values (none)
     Adding system startup for /etc/init.d/ssh ...
       /etc/rc0.d/K20ssh -> ../init.d/ssh
       /etc/rc1.d/K20ssh -> ../init.d/ssh
       /etc/rc6.d/K20ssh -> ../init.d/ssh
       /etc/rc2.d/S20ssh -> ../init.d/ssh
       /etc/rc3.d/S20ssh -> ../init.d/ssh
       /etc/rc4.d/S20ssh -> ../init.d/ssh
       /etc/rc5.d/S20ssh -> ../init.d/ssh
  • should work now :-)

    $ ls -l /etc/rc1.d/*ssh*
    lrwxrwxrwx 1 root root 13 2011-01-18 21:33 /etc/rc1.d/K20ssh -> ../init.d/ssh
