I'm on Linux (Ubuntu 20.04) and I make vpn connection using openvpn to my workstation which is windows 10 (I use RDP connection through remmina) when I use my workstation IP address I'm able to ping and connect but when I use my workstation name (ex: wks-eshirvana) I'm able ping my workstaion name but remmina doesn't recognize it and I get error message:

Could not find the address for RDP server "wks-eshirvana"

(note: I'm able to use machinename when I'm on windows)

is there a workaround to use my workstation machine name instead of ip address?

update:

the error I get is :

[09:58:00:867] [12184:12296] [ERROR][com.freerdp.core] - freerdp_tcp_is_hostname_resolvable:freerdp_set_last_error_ex ERRCONNECT_DNS_NAME_NOT_FOUND [0x00020005]

I created a bug in GitLab, I paste the answer from remmina developers, It didn't work fro me but might work for someone else:

This is the error raised by the FreeRDP library, and it happens, most probably, because of a confinement issue. FreeRDP uses getaddrinfo to obtain the hostname IP address. Unfortunately I don't know how to help you as I have a VPN (OpenConnect) and it works perfectly even with the Snap package.

Try to remove (backup your profiles before) remmina and reinstall with:

 sudo snap install remmina --devmode

It should install remmina without any restrictions, and let me know if it works.

  • Maybe there is some problem on DNS resolution. You can have a try to add a entry pointing your workstation name to the IP address in the hosts file to see if you can use the name for connection.

  • @seven but how about when it has dynamic up address that changes? In windows , Remote Desktop uses machine names and its fine , in Linux it should be the same

I have the same setup, linux-vpn-windowsmachine. No workaround should be needed, must be something simple. Start with nmcli command to see if there is a nameserver on the vpn connection. Mine looks like this:

VPN myvpnname VPN connection
        master wlp59s0, VPN, ip4 default
        inet4 192.168.0.211/24
        route4 172.16.1.0/24
        route4 0.0.0.0/0
        route4 192.168.0.0/24
...
DNS configuration:
        servers: 192.168.0.231 192.168.0.244
        domains: vpnxxx.mydomainxxx.com
        interface: tap0
        type: vpn

  • OK great - I am using remmina myself, so it should be workable if you ever need it in the future

  • well, its not for me for some reason, I even created a bug in gitlab, and seems like there is something even developers can't find out how to solve

  • Alright that won't be simple as I first claimed. in case it helps with the bug report i have ubuntu 19.10, remmina 1.3.4, and openvpn 2.4.7-1ubuntu2
