5.7. System Daemons

5.7.1. mdadm

The mdadm program controls Linux md devices (redundant arrays of independent disks implemented in software, or software RAIDs). It can create, assemble, report on, and monitor arrays and can also move spare storage between arrays when needed.
The version of mdadm in Fedora 13 has been upgraded from version 3.0.2 to version 3.1.1. The most important changes include:
  • you can no longer stop a container when the members within it are still active.
  • a homehost parameter has been added to the AUTO config line. When used with the -all option, this parameter causes mdadm to assemble any array that belongs to this host automatically, but not to assemble any other arrays automatically.
  • previously, arrays with interdependencies had to be listed in mdadm.conf in a specific order. Now, the order is not important.

5.7.2. openssh-server

Openssh-server is a open-source server daemon for the SSH protocol.
The version of openssh-server in Fedora 13 has been upgraded from version 5.2p1 to version 5.4p1. The most important changes include:
  • SSH protocol 1 is disabled by default.
  • added support for PKCS#11 tokens.
  • added support for certificate authentication of users and hosts using a new, minimal OpenSSH certificate format (not X.509).
  • added a netcat mode that connects standard out on a client to a single port forward on a server.
  • added the ability to revoke keys to sshd and ssh.
