I want to check which version of vncserver I am using in my linux box. What is the command for that?
When I run
P.S: I am running Red Hat Enterprise Linux Server release 5.8 (Tikanga)
To find out from what package (and version) a file comes, you can do
Check the reports for RHEL updates, I believe they either send them to all users, are available on a (read-only) mailing list, and on their website.
