such as prefill username and password:
username=ask{base64}YmFzZTY0
username={base64}YmFzZTY0
password=ask{base64}YmFzZTs2NCFwYXNzd29yZCM=
password={base64}YmFzZTs2NCFwYXNzd29yZCM=
';', '#', '!' means comment in .ini files. If prefill username or
password contains such symbols, these can be provided base64 encoded.
If you run xrdp with a Unix Domain Socket (UDS) for the port specified in
/etc/xrdp/xrdp.ini then only root can connect to it.
Test case:
1. Edit /etc/xrdp/xrdp.ini to set "port=/var/run/xrdp-local.socket".
2. Restart xrdp.
3. Run the following, as a non-root user.
socat TCP-LISTEN:12345 UNIX-CONNECT:/var/run/xrdp-local.socket &
rdesktop localhost:12345
Expected behaviour: rdesktop starts up and displays the logon dialog.
Observed behaviour: rdesktop exits with "ERROR: Connection closed" and
socat exits with "Permission denied". (But it suceeds if root runs
socat.)
UDS files are created by trans_listen_address() and given permissions
0660, so only root can connect to it. In this case, for the RDP client
connection, it it fine for any user to connect so it should be given
permissions 0666.
Note that this is only relevant when the port in /etc/xrdp/xrdp.ini has
been set to create a UDS instead of a TCP socket. When a TCP port is
created any user (including remote users, unless the loopback interface
is used) can connect so this is not less secure.
The UK/GB keyboard doesn't work properly connecting to xrdp with xorgxrdp.
It does work when connecting to xrdp with x11vnc, however.
This is because the layout is not declared in xrdp_keyboard.ini. It needs
to be called "gb" not "uk". (There are other layouts that have
km-nnnn.ini files that aren't declared in xrdp_keyboard.ini, so they might
have the same bug, but I haven't tested that. This is analagous to the
commits for the "ch" and "pl" layouts.)
Test case:
1. Use a PC with the UK/GB keyboard layout.
2. Create /etc/xrdp/startwm.sh as follows:
#!/bin/sh
export LANG=en_GB.UTF-8
export MDM_LANG=en_GB.UTF-8
export XTERM_LOCALE=en_GB.UTF-8
xterm
exit 0
3. Connect using rdesktop to localhost (from a session where the same
environment variables are defined).
4. Test layout-specific keys such as:
\ (backslash)
| (bar)
# (numbersign)
~ (asciitilde)
£ (sterling: Shift-3)
€ (EuroSign: AltGr-4)
These keys should produce the appropriate symbol but they don't. With
the change in this commit the keys produce the correct symbol.
As some clinents (AFAIK Windows 10) always send domain name, the backend
module is not selected properly. This causes the default usage with
Windows 10 fails with 'xrdp_wm_log_msg: Section "XXX" not configured'.
Use XRDP_SOCKET_PATH in file_loc.h
Don't define any non-socket paths in file_loc.h, they should come from
the makefiles.
Define all paths unconditionally, they should not be defined elsewhere.
Pass XRDP_SOCKET_PATH as environment variable to the backends.
caused by 9c31bd5. This is not a complete fix but just a workaround
because keylayout value of Japanese keyboard can be other than these
4 values. This workaround still doesn't cover all JP keyboards.
- 0x00000411
- 0xe0010411
- 0xe0200411
- 0xe0210411
Looking for `0411` in lower 16 bits is enough to detect JP keyboards.
self->line_size should be calculated in xrdp_bitmap_create_with_data()
The code was in the original noorders branch but got lost. Without this
fix, the image is garbled.
The client should be configured with compression disabled, or it will
disconnect. That's a known problem.
The removal of "xserverbpp=24" from the Xorg entry lead to a regression.
Clients with a different bpp would not reconnect to an xorgxrdp session
if the client's bpp is different, even though xorgxrdp is always using 24
bpp.
Imply "xserverbpp=24" for "code=20" in xrdp.ini.
Setting autorun to empty keeps X11rdp as the default backend for
autologin (since it's the first section), but it also enables the backend
selection by the domain name.
Describe the autorun interaction with the domain name both in the config
file and in the manual.
Since libpainter is going to become a subpackage, we can make librfxcodec
a subpackage as well.
With this change, librfxcodec is configured, built and linked to xrdp
automatically if enabled by "--enable-rfxcodec"
librfxcodec is packaged by "make dist" regardless of "--enable-rfxcodec"
librfxcodec/confgure is run unconditionally, it's needed for "make dist"
to work. But librfxcodec is only compiled if enabled.
xserverbpp affects X11rdp and Xvnc, but not Xorg. No need to have
xserverbpp in the Xorg section where it has no effect. Add commented out
xserverbpp to Xvnc, some users may want to experiment with that setting.
The pixman library in not part of xrdp. If users see that "xrdp_pixman"
is not found, they might assume it is some xrdp specific library.
The Automake conditional is still XRDP_PIXMAN, but the pkg-config
variables become PIXMAN_LIBS and PIXMAN_CFLAGS.
If no domain is passed, self->session->client_info->domain is an empty
string that is incorrectly treated as if the domain were passed by the
client.
The regression was introduced in fc753a95, when an incorrect check for
non-empty domain was added. That check was removed in 67119ecc based on
coverity report, leaving no trace of the original intention.
Check domain both for '_' and '\0' as the initial character. In either
case, select the first session type section in xrdp.ini.
upper 16 bits of keylayout value indicates keyboard layout.
lower 16 bits of keylayout value indicates country/language.
If the keymap file doesn't match exactly to keylayout value,
the typical keyboard of the country/language should be used.

Make section names equal to the names in the "name=" setting to avoid
confusion and the need to renumber sections. Avoid "sesman-" in the
names, it's not helpful to the user. Move "Xorg" just below "X11rdp",
that would give xorgxrdp more visibility.
AM_CPPFLAGS is a documented Automake variable for C preprocessor flags
that should not be overridden when compiling the package.
There is no need to have two additional variables that are ultimately
merged into AM_CPPFLAGS.
Their names are also confusing. EXTDA_DIST is a documented Automake
variable. Everything else that starts with "EXTRA" is not.
