Instalacija KERBEROS protokola

From MediaWiki

Instalacija i podešavanje KERBEROS protokola (služi za proveru identiteta korisnika). KERBEROS je prijavljivanje tipa prijavi-se-samo-jednom (Single Sign On), koje korisnicima omogućava da se samo jednom prijave na sistem i da nakon toga, u skladu sa svojim ovlašćenjima, imaju pristup svim resursima u sistemu (ili mreži).

1. Otvoriti Terminal i ukucati

   sudo apt-get install krb5-user

   Uneti šifru.

2. Nakon završene instalacije, treba izmeniti fajl ssh_config:

   sudo gedit /etc/ssh/ssh_config

   U fajl iskopirati sledeće (umesto ******** treba napisati username), sačuvati i zatvoriti ga:

# This is the ssh client system-wide configuration file.  See
# ssh_config(5) for more information.  This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.

# Configuration data is parsed as follows:
#  1. command line options
#  2. user-specific file
#  3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.

# Site-wide defaults for some commonly used options.  For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.
