Is it safe to type a password in a VNC client connected to a server to access another server?

I am using VNC GUI client from my Desktop to connect to a remote (ubuntu) server, say S1. From the remote server (S1), I will be logging into another server (say S2) via SSH. Via VNC client, I will be typing in the SSH password of S2 on putty running on S1 to gain access to S2. Is this a safe way of doing things?

Real Vnc – System has not been booted with systemd as init system (PID 1). Can’t operate. Failed to connect to bus: Host is down

Once I install and try to run the program I get this message "System has not been booted with systemd as init system (PID 1). Can’t operate.
Failed to connect to bus: Host is down" .

I try to create a .service so it runs on systemd but can’t manage to make it work. Any ideas?

networking – Does VNC handle dynamic IP address automatically?

I’m new, and I’m setting up a Raspberry Pi with VNC server that will be always ON behind a normal router on a Dynamic IP address location. Is VNC server going to work seamlessly if/when my IP address changes ? Or am I going to discover I can’t communicate, and do setup all over again ? Thanks for help.

VNC with Xinetd and xdmcp no longer work after upgrade to 18.04.4

I installed Ubuntu 18.04.3 desktop from DVD iso, and then enabled on demand vnc service (tigervnc) with xinetd and xdmcp. Everything worked fine.

After I upgraded to most recently packages (apt upgrade -y), I can still get login screen and desktop. But if I open any application, the application window will become black, as show below:

application windows is black

Here is my configurations:



Are there other VNC servers for macOS other than the built in one?

The built in VNC server is not sufficient for my needs as I cannot change settings of the VNC server.

I tried to run Vine Server (OSXvnc) but the application crashes on launch.

Are there any other VNC servers that run on macOS?

ssh – Fix server screen resolution after remote vnc connection (xubuntu 18.04)

I am connecting remotely to my xubuntu desktop with vnc using

ssh -L5901:localhost:5900 -o ServerAliveInterval=10 remoteme@myserver

and then on the server side

sudo x11vnc -rfbauth ~/.vnc/passwd -scale 0.95x0.95 -auth /var/run/lightdm/root/:0 -display :0

I mean, I had to use the -scale option to resize monitor to fit my client's monitor where I used a local vncviewer.
And I had to use sudo x11vnc since there was no user connected.

Occasionally I go to visit myserver and connect directly, but its screen size and resolution are wrong and there is no way to fix it using standard GUI commands.

Before making matters worse, I'd appreciate a suggestion for an easy fix.

Thank you,


video streaming: any way to estimate the bandwidth needed to use VNC?

I need to stream Linux software to Windows. Depending on your setup, I will have to stream 2.4 or 8 screens in 1080p. However, I cannot install VNC to test it myself (restrictions on my computer).
Is there a way to estimate the approximate flow I will need to stream my software?

macos: artifacts of gradual occurrence / disappearance notification windows when using VNC / Screen Share

I'm using Finder's "Connect to Server" with a "vnc: // …" address to access a desktop remotely, from Mac to Mac (both run the latest Catalina), and I've always had a problem with The notification windows (in the upper right corner) fade / disappear, leaving a "ghost" of the window behind indefinitely. I can't click on things behind windows, and clicking on one of these doesn't do what I normally would if the window were completely opaque. For example, this shows a couple of notifications from MS Outlook / Update, and a notification from the App Store.

Ghost notification windows

And here it is with an open menu below. You can only click a menu item by entering between the window openings (only the first item is accessible in this example):

With menu

I can make them disappear temporarily by activating the "DO NOT DISTURB" mode for notifications. But I am looking for a way to correct this behavior without disabling notifications. I still don't know if this happens with other VNC viewers besides the one integrated in MacOS / Finder. I can try that later. And I also plan to try to disable animations if no other solution is available. (How to disable all animations in OS X

Incidentally, this has also been happening to me with previous versions of MacOS.
