I‘m trying to use Cinelerra video editing and compositing software under Linux operating systems. However, I’m getting the following error:

MWindow::init_shm: /proc/sys/kernel/shmmax is 0x1000000.
It should be at least 0x7ffffff for cinelerra.

How do I fix this problem?

NFS was not designed with security in mind, and has a number of weaknesses, both in terms of the protocol itself and because any NFS installation must expose several daemons, running on both servers and clients, to network attack. I use my Debian / Ubuntu Linux based server only to server web pages and nothing else. How do I disable NFS services under Debian or Ubuntu Linux?

I‘m using the ldd command to get information about /usr/local/nginx/sbin/nginx binary and I see linux-gate.so.1 library. However, I’m unable to find out this file anywhere on the system? What is linux-gate.so.1 and how do I copy this file?
