CD-ROM Digest is a program that checks a multi-track CD-ROM. It reports the MD5 digest and size for each track on a CD-ROM. The digest is done as the track is read, without dumping CD-ROM data on the hard drive. This tool helps users that are burning a multi-track CD-ROM to check the result.
Virtual server monitor (vsmon) is a monitoring tool for Linux-VServer that gives a system administrator a global view of all vservers running on his park. vsmon aims to be a monitoring solution only. For now, it does not offer control over the vservers' life cycle (e.g. provisioning, start, stop, and restart operations). To use vsmon, you must deploy one backend on each vserver host and one frontend, preferably in its own vserver.
userchroot is a small program which, in addition to doing a regular chroot, will also switch working directory once in chroot and drop privileges back to pre-suid values. It is intended to ease constructing chrooted user-driver services (running stfp-server in a restricted namespace for example). In order to conserve system resources, it is implemented in C. This makes it more suitable for higher load scenarios than scripts.
