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.
