xrdp session manager window fails to appear

`sudo xrdp` has no output.

As for `xrdp`

$ xrdp
Could not start log
Could not start log
error opening log file [The log is not properly started]. quitting.

From Arch Wiki:

You should be able to connect an RDP client to the host on the default RDP port (3389). If successful, you will be greeted with the xrdp session manager window which allows you to choose between Xorg or Xvnc sessions and provides inputs for user authentication.

No session manager window appears.

Re: xrdp session manager window fails to appear

/var/log/xrdp.log
http://ix.io/4o17

I removed the .pid file as mentioned around the 20230214-13:41:27 mark, and the error said that the address was probably already in use.

sudo rm /var/run/xrdp.pid

I don't see how the address could be in use as I keep deleting the pid and yet xrdp never displays the session manager.

In case it's useful to anyone:
/var/log/xrdp-sesman.log
http://ix.io/4o16

Re: xrdp session manager window fails to appear

Do you have also xorgxrdp installed?
Do you use firewall - if so, is port 3389 enabled?

Re: xrdp session manager window fails to appear

I had not installed xorgxrdp and I now have. No change.

I have iptables installed. I have never played with ports before, but I did ran the following commands:

  sudo iptables -I INPUT -p tcp --dport 3389 -j ACCEPT
  sudo iptables -I INPUT -p udp --dport 3389 -j ACCEPT
  sudo ip6tables -I INPUT -p tcp --dport 3389 -j ACCEPT
  sudo ip6tables -I INPUT -p udp --dport 3389 -j ACCEPT

Still nothing happens.

Current rules in iptables:

$ sudo iptables -nvL
Chain INPUT (policy ACCEPT 9590 packets, 14M bytes)
 pkts bytes target     prot opt in     out     source               destination         
    0     0 ACCEPT     17   --  *      *       0.0.0.0/0            0.0.0.0/0            udp dpt:3389
    0     0 ACCEPT     6    --  *      *       0.0.0.0/0            0.0.0.0/0            tcp dpt:3389

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         

Chain OUTPUT (policy ACCEPT 5570 packets, 831K bytes)
 pkts bytes target     prot opt in     out     source               destination

Re: xrdp session manager window fails to appear

Are you connecting from Windows or Linux machine? Any error message?
Log from such connection?

Re: xrdp session manager window fails to appear

I am connecting a Linux Mint desktop to my Arch Linux laptop via xrdp. I am also using Zerotier to create a private tunnel.

I assumed that the window session manager would pop-up without connecting either device, but are you implying that the session manager will only appear if there is an ongoing connection between the two devices? Sorry for the obvious question, but I am not very familiar with networks or the RDP.

Re: xrdp session manager window fails to appear

There will nothing popup on rdp server (arch) side. Window will popup on client side (mint) , when you try connect
to server (arch) asking for your credentials for server.
Which program you use on Mint desktop for connecting to Arch laptop (my recomendation: remmina)?
In remmina on Mint you create profile for connection to Arch linux (ip adress, credentials).

Re: xrdp session manager window fails to appear

Sorry, I wrote that wrong. I am using my Arch laptop to remote access my dad's linux mint desktop, so that I can access my dad's desktop from abroad.

I also realise now that xrdp is not a client, and so I'll need to install a client for my Arch laptop. If I've understood things correctly, do you recommend using Remmina for Arch?

Re: xrdp session manager window fails to appear

Yes - I recommend use remmina on your archlinux nb.
You don't need xrdp/xorgxrdp installed on your notebook, you need to instal it on your dad's desktop.
Installation on Mint should be the same, as on Ubuntu - there is lot of tutorials on Youtube, how to do it.

Re: xrdp session manager window fails to appear

I installed Remmina on Arch and xrdp is now active on Mint. I put the server, name, and passwd of the Mint account on Remmina. However, I am now outside of the same network as that desktop. I am not sure how I can connect from Arch to Mint using this method when outside the network. Do I need to create an SSH tunnel or something?
