Hello
I am a new user, apologies if this question should go somewhere else.

--
I had installed DFBSD 5.6.2 on a virtual box vm, it is Natted
with ports 22 and 3389 forwarded, such that I can login to FBSD from SSH and from RDP clients

--
I had installed XRDP and added it to rc.conf, so that it starts on startup.


# cat /etc/rc.conf
# Basic rc.conf, adjust according to your needs
#
nfs_reserved_port_only="YES"
sshd_enable="YES"
nfs_client_enable="YES"
rpc_umntall_enable="NO"
dumpdev="/dev/serno/VB363b1113-01a188d7.s1b" # via installer configuration
hostname="dfbsd-vb-01.mydomain.com"     # via installer configuration
ifconfig_em0="DHCP"     # via installer configuration

#manually added start
xrdp_enable="YES"
#manually added end
dfbsd-vb-01#

---

When trying to connect to dfbsd from Windows and Linux RDP client (remmina), I am getting connection errors (windows client just exits immediately)

I had also noticed when XRDP starts up on DFBSD, there is an error message


dfbsd-vb-01# cat xrdp.log
[20190824-16:09:04] [DEBUG] Testing if xrdp can listen on 0.0.0.0 port 3389.

Sockstat does not reveal anything strange :

Wanted to ask what steps I should take to troubleshoot the problem further.


I tried to look at xrdp source, but not sure if the error message in the log is misleading, or I am mis-interpreting it

https://github.com/neutrinolabs/xrdp/blob/e7c0b11336bce95fbd2c8a5624bb476f038536de/tests/gtcp_proxy/gtcp.c

seems to be a g_tcp test directory.


Or may be somebody can confirm that they can successfully run XRDP on their 5.6.2 install, if that's the case, then this is would be a problem on my side


Thank you in advance
