Remote System Description
- Server (OS name and version): xubuntu 19.04
- Special notes regarding the remote system (i.e. gateways, tunnel, etc): DDNS provided by Synology NAS, port forwarding setup correctly.
Hi all, thank you so much for the work you've done on this program. I'm not very good with this stuff but after some wrangling have managed to set it up and it's already been incredibly useful. So: thanks again! I'm trying to dial into my remote machine by booting it up from a command in my NAS which sends a WOL packet to the machine on the same LAN. However, since I'm remote, I don't know with certainty that the WOL worked, so the machine might be off, and I have no way to tell. My Remmina setup has worked before so I presume (but don't know 100%) that the unchanged settings should be correct. I've tried to WOL and Remmina in with VNC but am getting the TLS handshake failed problem. Reading about this here, it occurs to me that some/many of the possible reasons for this error are not likely or even impossible (?) when Remmina is taking care of much of the config. Would it be possible for this error to be more informative regarding the actual problem? Or is that outside of the scope of TLS? If it could instead say:
- The remote computer did not respond
- The remote computer has a different system time
- (etc etc)
That would be incredibly helpful in allowing users to diagnose their problems. For my example, I presume if my machine is off, "An illegal TLS extension was received" actually means "NO TLS extension was received"?
The external tools are informative however. NSlookup: "server can't find myservername:5900: NXDOMAIN". Ping: "myservername:5900: Name or service not known" If I just punch "myservername:5900" into a browser it returns: RFB 003.007 which apparently means unknown server
Thanks in advance.
