when I use mobaxterm to connect my work PC by vnc option, I get error "no configured security type is supported by 3.3 vnc viewer "
I searched and find that setting encryption to "let vnc server choose" or "prefer on" can solve this situation.
but mobaxterm seems to have no option to set this. And unfortunately I can not change my work pc(server) vnc setting, only IT department has the permission
so it means mobaxterm is not fit for me?
Many VNC clients may not work with the newest security options that are present in the VNC Server that is provided with Raspberry Pi OS. You might see an error like this “vnc no matching security types” or "no configured security type is supported by 3.3 vnc viewer"
The solution for the home network is to downgrade the security options on the server:
Edit this file:
/root/.vnc/config.d/vncserver-x11
It contains 2 line in my version (Bullseye)
Add these lines to the end of the file:
Authentication=VncAuth
Encryption=AlwaysOff
Password=e0fd0472492935da
Change the password like this:
sudo vncpasswd -service
You will be prompted for the new password
Then reboot the Pi
Real VNC Server 6.10.1 on ubuntu 22
MobaXterm v22.1 on windows11
vnc server options
/security tab
encryption: prefer off
authentication: vnc password
/Users & Permissions tab
set password
succeed!

Problem Summary:
I can SSH to remote host using Kerberos and PuTTY on Windows 10, but I can't connect using VS Code.
Steps I have tried:
I used MIT Kerberos Ticket Manage to generate a Kerberos API key.
Then, in PuTTY I selected both “Attempt GSSAPI authentication” and “Allow GSSAPI credential delegation” . After entering the host name and my username, I can successfully connect to the remote host in PuTTY.
However, I cannot connect to the remote host in VS Code using the following SSH config file:
Host my-host
GSSAPIAuthentication yes
GSSAPIDelegateCredentials yes
User my-name
My error looks like this:
I learned from this Stack Overflow answer that Windows "has two Kerberos libraries (MIT KfW & Windows SSPI)", so my suspicion is that VS Code is not looking for GSSAPI libraries in the correct order, like the PuTTY screen shot. But I don't know how to specify the order like in PuTTY.
Please help! Thanks!
I am trying to connect to a remote system which has CentOS running on it from a Windows machine. I am getting the following error:
My remote computer is on and is available on the network. I tried following the steps mentioned on this website http://www.techotopia.com/index.php/Remote_Access_to_the_CentOS_6_Desktop to enable remote access on centos as well.
Currently I can access the remote sever through commandline utility like Putty only.
I use VNC for remote GUI admin work on CentOS device's from windows its nice and easy to set up and use, below are links to CentOS 6.5 set up guide and 7
https://www.howtoforge.com/vnc-server-installation-centos-6.5
https://www.howtoforge.com/vnc-server-installation-on-centos-7
Let me know how you get on :)
As posted by PaulM, I followed the steps in the website to install VNCServer on the centos machine.
To connect from my linux machine, I wrote the following commands:
vncviewer
IPAddress:5901
Adding the port number specifically made it work
CentOs to centOs Only
No Need Any Softwares Already Centos have TigerVnc Viewer
1.Enable Remote desktop in your centos system
Goto System-->Preference-->Remote Desktop
**i.Enable allow other user to view your Desktop**
**ii.Enable allow other user to control your Desktop**
**iii.You must confirm each access to this machine allow or cancel**
**iv.if you ask any password to enable and type your password**

Some one connect your system its enable to shows the icon on top panel.
I'm trying to do some local RDC testing using VirtualBox. The host is OSX.8, the VM is ubuntu, and VirtualBox is version 4.1.22.
The VM starts fine without any problems. I shut it down and choose "Enable Server" from the Remote Display section of the Display options and start again, and again it starts fine. Note that the port is left default and the authentication is "null".
I start Microsoft's RDC (v2.1.0) and type in 'localhost' and get: You were disconnected from the Windows-based computer because of network problems.
I try 127.0.0.1 and get the same error. Then I type in the IP of my (host) computer and get the same error. I know the loopback address avoids the firewall but I turned it off anyway and got the same error.
I get the same error whether I'm using NAT networking or bridged. What am I doing wrong?
I should note that this is a vanilla install of VirtualBox and I haven't added any extensions or guest additions or anything like that.
Seems I'm doing everything right. What am I missing? Thanks for the help!
Problem Solved! You have to install the "VirtualBox 4.1.22 Oracle VM VirtualBox Extension Pack" (available on the VB download page) to make RDC work. I wish it would tell you this when you click "enable server" but I guess that's asking too much. I hope this helps someone else.
I'm trying to set netBeans remote project and I'm having pretty much trouble with it. I've started a PHP Application from Remote Server and in the last confirmation step it throws error on me.
No files available for download. Try to check Passive mode in the remote configuration.
In the log output it fails there:
> 215 UNIX Type: L8
> PORT 192,168,5,217,196,73
> 500 Illegal PORT command.
Did anyone have same problem with setting up remote connection? Please help.
To establish an FTP connection, choose either of the options below:
Turn off the Windows firewall.
Configure Windows Firewall for a passive mode FTP server as follows:
Open an Administrator command-prompt.
Click Start > All Programs > Accessories.
Right-click Command Prompt, and then click Run as Administrator.
Run the following command:
netsh advfirewall firewall add rule name=FTPService action=allow service=ftpsvc protocol=TCP dir=in
Disable stateful FTP filtering so that the firewall does not block any FTP traffic:
netsh advfirewall set global StatefulFTP disable
This seems to be the top answer whenever anyone is looking for how to set netbeans into passive mode. Despite the advice always being "set the ftp into passive mode" for those using Mac OS and Netbeans you may never seem to find it.
Right click on the project
Select Properties
Select Run Configurations
Select Manage
Select your_ftp_connection on the left column
Scroll down
The only way I fixed this was to switch to using SFTP. This obviously requires that you've set up SFTP (FTP over SSH) access to your server.
In the Run Configuration, when it asks you for the Remote Connection:
Click on 'Manage'
Click on 'Add...'
Select SFTP as the connection type
Fill in the rest of the details as if it were a normal FTP connection.
Turning plain FTP Netbeans connection into passive mode solved the problem for me.
Please Check Passive Mode; i had faced the same issue; after checking it; resolve this issue.
There is no way to find the passive mode in a OSX. It's a Netbeans bug... So I won't be able to develop on netbeans using my Mac. Already tried to download last version.
For me the solution was to check Passive Mode on the client and to do following things on the server side
in /etc/vsftpd.conf
pasv_enable=Yes
pasv_max_port=10100
pasv_min_port=10090
then in terminal
iptables -I INPUT -p tcp --destination-port 10090:10100 -j ACCEPT
service iptables save
service vsftpd restart
I have Installed GTK on a Linux machine.
I am connecting To Linux Machine from a Telnet Session to compile the GTK programs
From A Windows Machine. I am using Cygwin on Windows Machine. but i am not able to see
GUI output of my GTK program on my Windows Machine.
When i run program from my terminal i get this error:
(helloworld:22576): Gtk-WARNING **: cannot open display:
I tried solutions from every answer posted, but no use now i am getting following error:
$ ./helloworld
Invalid MIT-MAGIC-COOKIE-1 key
(helloworld:22710): Gtk-WARNING **: cannot open display: 172.25.0.161:0
and i am getting following error on my Cygwin console:
client 6 rejected from IP 172.25.0.91 Auth name: MIT-MAGIC-COOKIE-1 ID: -1
You must set the DISPLAY variable in your telnet session to the IP address or DNS name of your Windows machine and append ":0"
export DISPLAY=windows.your.domain:0
And you must start an X server on the Windows machine (comes with Cygwin but you must start it).
You need to run the X window system (install with Cygwin) on your Windows-box and enable remote connections (probably with xhost). Set the DISPLAY-variable on your Linux-box to the address of your Windows-box and :0, as such:
export DISPLAY=192.168.1.123:0
I can recommend using ssh rather than telnet, for security reasons. In this case you do not need to enable remote connections with xhost, and you do not need to set the DISPLAY-variable. You only need to enable X forwarding.
You should install X-server on your windows machine and make sure you have DISPLAY set to yourmachine:0 or something like that. Or better yet use ssh instead of telnet (e.g. putty) and tunnel your X connection. You'll have to do a bit on your own research, though, because the complete answer would be a lengthy one.
Install an small X server on Windows XMing32, then run it, use putty as a console client, and check "X11 Forwarding" in Connection->SSH->X11.
Unfortunately, X11 Forwarding is not available through Telnet, you must run a SSH server on the target Linux and connect through SSH. (See if /etc/ssh/sshd_conf requires enabling X11 Forwarding too).
