I think I may have found an/the issue here.
Comparing two systems (one that works and one that does not), I noticed
that "/usr/local/sbin/xrdp-chansrv" was not even running on system that
wasn't working. So, I manually ran it to find it was missing some
libraries which I checked with "ldd":
#~ ldd /usr/local/sbin/xrdp-chansrv
libcommon.so.0 => /usr/local/lib/xrdp/libcommon.so.0 (0x800267000)
libSM.so.6 => /usr/local/lib/libSM.so.6 (0x800280000)
libICE.so.6 => /usr/local/lib/libICE.so.6 (0x80028a000)
libXfixes.so.3 => /usr/local/lib/libXfixes.so.3 (0x8002a7000)
libXrandr.so.2 => /usr/local/lib/libXrandr.so.2 (0x8002af000)
libX11.so.6 => /usr/local/lib/libX11.so.6 (0x8002bc000)
libfdk-aac.so.2 => not found (0)
libopus.so.0 => /usr/local/lib/libopus.so.0 (0x8003fd000)
libmp3lame.so.0 => not found (0)
libthr.so.3 => /lib/libthr.so.3 (0x80046f000)
libcrypto.so.111 => /lib/libcrypto.so.111 (0x80049a000)
libssl.so.111 => /usr/lib/libssl.so.111 (0x800787000)
libc.so.7 => /lib/libc.so.7 (0x80081c000)
libXext.so.6 => /usr/local/lib/libXext.so.6 (0x800c0f000)
libXrender.so.1 => /usr/local/lib/libXrender.so.1 (0x800c23000)
libxcb.so.1 => /usr/local/lib/libxcb.so.1 (0x800c2f000)
libm.so.5 => /lib/libm.so.5 (0x800c58000)
libXau.so.6 => /usr/local/lib/libXau.so.6 (0x800c8a000)
libXdmcp.so.6 => /usr/local/lib/libXdmcp.so.6 (0x800c8f000)
Here, I noticed that both "libfdk-aac" and "libmp3lame" are missing
which is keeping xrdp-chansrv from starting. I was able to install
"fdk-aac-2.0.0" via "pkg install" without any issues but installing
"audio/lame" does not appear to be an option via "pkg". Apparently,
there is a licensing issue. So, this needed to be built from ports. I
would imagine that these are important to people using sound (I am not)
so some audio dependencies should remain. However, I'm not sure it
should be "audio/lame" if there is not a package available for it.
Perhaps finding an alternative or removing it as a dependency from the
xrdp-devel package? Not sure.
Anyhow, getting these two libs installed fixed the chansrv timeout issue
for me. So, hopefully that can help troubleshoot the package install of
xrdp-devel (I haven't tried the port but I'd imagine it probably works
