I have a remote server which I can't access physically, for the last couple of weeks I could connect to it using both FTP protocol and VNC remote desktop. I changed the "Desktop Sharing" Program in ubuntu to get acess to its desktop. from yesterday, my access to my server using VNC protocol is not possible. I can ping my server and Connect to it using Filezilla for FTP transmission but When I want to connect to it using VNCviewer or SSH it gives the following error message:
VNC VIEWER :
"The connection was refused by the host computer"
ssh: connect to host 10.136.9.153 port 22: Connection refused
I can only connect to my server using FTP protocol. I don't have a vnc server installed on my server so I think maybe the "Desktop sharing" program is failed. firewall if off. Also I can't change any files in /etc/ or /var/ or any root folders using FTP protocol. is there any way to access my server in this situation ?
Edited: I've rebooted my system by cutting off the electricity but still it gives the above error message.
