Notes
- 1.
This is the same wordlist file that was used in Chapter 8. This wordlist does not contain the password selected for these systems (password1!), so it has been added to this file.
- 2.
Well, OpenSSH usually respects TCP Wrappers. Recent versions of OpenSuSE may or may not be compiled with support for TCP Wrappers. OpenSuSE 13.2 does not respect TCP Wrappers, OpenSuSE 42.1 does, while OpenSUSE 42.2 and OpenSuSE 42.3 do not. Sigh. See https://bugzilla.opensuse.org/show_bug.cgi?id=931429 .

If the reader does not specify an output directory, the default is to store the results in /usr/local. If this is done, or if a different output directory is selected, the subsequent commands need to be modified to reflect the change.
- 4.
Recall that this file was manually copied to this location from the source by the administrator; if the administrator selects a different directory for SSHGuard, this will be located elsewhere. Note also that the location of sshg-fw-iptables is in a different location.
- 5.
The sample file /opt/sshguard/etc/sshguard.conf suggests using the -t option for journalctl. Recall from Chapter 10 that the -t option for journalctl is not supported on OpenSuSE 13.2.
- 6.
The Server Manager may need to be refreshed before the option to select Shares appears.
- 7.
- 8.
The passwords are all “password1!”
