i.e. there -can be an -.I rlogin -service running on the machine ABC, which -is different from the rlogin service running on -the machine XYZ. -The third part of a Kerberos name -is the -.I realm. -The realm corresponds to the Kerberos service providing -authentication for the principal. -For example, at MIT there is a Kerberos running at the -Laboratory for Computer Science and one running at -Project Athena. -.PP -When writing a Kerberos name, the principal name is -separated from the instance (if not null) by a period, -and the realm (if not the local realm) follows, preceded by -an ``@'' sign. -The following are examples of valid Kerberos names: -.sp -.nf -.in +8 -billb -jis.admin -srz@lcs.mit.edu -treese.root@athena.mit.edu -.in -8 -.fi -.PP -When you authenticate yourself with -Kerberos, -through either the workstation -.I toehold -system or the -.I kinit -command, -Kerberos -gives you an initial -Kerberos -.IR ticket . -(A -Kerberos -ticket -is an encrypted protocol message that provides authentication.) -Kerberos -uses this ticket for network utilities -such as -.I rlogin -and -.IR rcp . -The ticket transactions are done transparently, -so you don't have to worry about their management. -.PP -Note, however, that tickets expire. -Privileged tickets, such as root instance tickets, -expire in a few minutes, while tickets that carry more ordinary -privileges may be good for several hours or a day, depending on the -installation's policy. -If your login session extends beyond the time limit, -you will have to re-authenticate yourself to -Kerberos -to get new tickets. -Use the -.IR kinit -command to re-authenticate yourself. -.PP -If you use the -.I kinit -command to get your tickets, -make sure you use the -.I kdestroy -command -to destroy your tickets before you end your login session. -You should probably put the -.I kdestroy -command in your -.I \.logout -file so that your tickets will be destroyed automatically when you logout. -For more information about the -.I kinit -and -.I kdestroy -commands, -see the -.I kinit(1) -and -.I kdestroy(1) -manual pages. -.PP -Currently, -Kerberos -supports the following network services: -.IR rlogin , -.IR rsh , -and -.IR rcp . -Other services are being worked on, -such as the -.IR pop -mail system and NFS (network file system), -but are not yet available. - -.SH "SEE ALSO" -kdestroy(1), kinit(1), klist(1), kpasswd(1), des_crypt(3), kerberos(3), -kadmin(8) -.SH BUGS -Kerberos -will not do authentication forwarding. -In other words, -if you use -.I rlogin -to login to a remote host, -you cannot use -Kerberos -services from that host -until you authenticate yourself explicitly on that host. -Although you may need to authenticate yourself on the remote -host, -be aware that when you do so, -.I rlogin -sends your password across the network in clear text. - -.SH AUTHORS -Steve Miller, MIT Project Athena/Digital Equipment Corporation -.br -Clifford Neuman, MIT Project Athena - -The following people helped out on various aspects of the system: - -Jeff Schiller designed and wrote the administration server and its -user interface, kadmin. -He also wrote the dbm version of the database management system. - -Mark Colan developed the -Kerberos -versions of -.IR rlogin , -.IR rsh , -and -.IR rcp , -as well as contributing work on the servers. - -John Ostlund developed the -Kerberos -versions of -.I passwd -and -.IR userreg . - -Stan Zanarotti pioneered Kerberos in a foreign realm (LCS), -and made many contributions based on that experience. - -Many people contributed code and/or useful ideas, including -Jim Aspnes, -Bob Baldwin, -John Barba, -Richard Basch, -Jim Bloom, -Bill Bryant, -Rob French, -Dan Geer, -David Jedlinsky, -John Kohl, -John Kubiatowicz, -Bob McKie, -Brian Murphy, -Ken Raeburn, -Chris Reed, -Jon Rochlis, -Mike Shanzer, -Bill Sommerfeld, -Jennifer Steiner, -Ted Ts'o, -and -Win Treese. - -.SH RESTRICTIONS - -COPYRIGHT 1985,1986 Massachusetts Institute of Technology |
