Operating system supplies random bits, OpenSSL uses this to seed Unpredictable bits (as truly random as is available). With, and then periodically, with an initial segment of Pseudo-random number generator (PRNG) needs to be “seeded” to start Stream of random bits for its cryptographic needs. OpenSSH normally relies on the OpenSSL library to provide a The default is /var/run/sshd.pid.Ĥ.2.4.2 Random number generation -with-random= FILE Read random bits from given file, normally /dev/urandom -with-rand-helper Use external program to generate randomness Of the currently running daemon, can be changed via the The location of the OpenSSH pid file, where it stores the pid with-pid-dir= PATH Specify location of ssh.pid file with-xauth = PATH Set path to xauth programĬompile-time parameter. If OpenSSL isn’t installed in the usual place, /usr/local/ssl, use this option to with-ssl-dir= PATH Set path to OpenSSL installation OpenSSH when attempting to run a subprogram, and anĪlternative path for the superuser.

As a separate but related effort, another team maintainsĪ “portable” version that compiles on a variety of Unix flavors and OpenSSH is specifically for the OpenBSD Unix operating system, and is inįact included in the base OpenBSD installation.
