vino-server


Hi all,


Platform- Linux Version 4 Update 2(2.6.9-34.ELsmp)

In this server, Oracle database as well as applications tier is running.

When I gave top command, it was showing 'vino-server' process which has been eating up 90% to 99% CPU for two days. This was really heavy on Oracle server. And I've no idea about 'vino-server' and so unsure about killing this process or bringing down its priority. Later on it got low on CPU and what I noticed, usually it takes upto 10% of CPU......maximum.

But my query is:

1.) May I kill this process if this is not of much importance?
2.) If this process can't be killed, then may I set it to low priority?
3.) What is vino-server? You can also refer a document on this.


An early reply is appreciable........

Thanks in advance,
Kosys

Please excuse me while I answer your questions in reverse order.

3 - Vino is a remote desktop server integrated into Gnome which uses the VNC protocol. It allows a user to share his/her desktop session with one or more remote users. This can be view only, or remote users can take control of the keyboard and mouse. Really cool and quite handy.

2 - Well if you are the all-powerful root then you can do anything you want to any process. It's just a question of whether its a good idea.

1 - To disable this daemon, first, find out what users are running it. Then, log in as each user. Run the program vino-preferences (available in my Fedora 7 menu as System->Preferences->Internet and Network->Remote Desktop). Uncheck Allow other users to view your desktop.

Considering that the process was using a lot of CPU time then someone was connected to the desktop. The question is, who? This could be a sign of an intrusion. You really need to find out who started this program and why. If this is supposed to be running then care should be taken to be certain it is securely configured. If one or more users need remote desktop access and it's their most frequent method of access, then there is a more efficient way using vncserver and xinetd to create the VNC sessions on and as-needed basis.
