You can find precompiled binaries for the sample .exe files in ../data/http/fakefiles/
Debian Policy does not allow Windows executable binaries to be included
in Debian packages. To comply with this policy, starting with INetSim
version 1.3.0 the sample binaries for HTTP fakefile mode are compiled
from source at package build time. This means the (hashsums of the)
sample binaries changed and might change again with future releases.
If your setup relies on INetSim to continue serving a sample binary
(sample_gui.exe or sample_con.exe) included with INetSim versions
prior to 1.3.0 in HTTP fakefile mode, download
and unpack the files to /var/lib/inetsim/http/fakefiles/.
Then, replace all occurrences of 'sample_gui.exe' in the configuration
file (/etc/inetsim/inetsim.conf) by 'old-sample_gui.exe'.
This needs only to be done once after upgrading to INetSim version
1.3.0 or later.
