This can be used both by having the router get a ticket when -you login (boring), and by using Kerberos authenticated telnet to access -your router (less boring). The following has been tested on IOS -11.2(12), things might be different with other versions. Old versions -are known to have bugs. - -To make this work, you will first have to configure your router to use -Kerberos (this is explained in the documentation). A sample -configuration looks like the following: - -@example -aaa new-model -aaa authentication login default krb5-telnet krb5 enable -aaa authorization exec krb5-instance -kerberos local-realm FOO.SE -kerberos srvtab entry host/router.foo.se 0 891725446 4 1 8 012345678901234567 -kerberos server FOO.SE 10.0.0.1 -kerberos instance map admin 15 -@end example - -This tells you (among other things) that when logging in, the router -should try to authenticate with kerberised telnet, and if that fails try -to verify a plain text password via a Kerberos ticket exchange (as -opposed to a local database, RADIUS or something similar), and if that -fails try the local enable password. If you're not careful when you -specify the `login default' authentication mechanism, you might not be -able to login at all. The `instance map' and `authorization exec' lines -says that people with `admin' instances should be given `enabled' shells -when logging in. - -The numbers after the principal on the `srvtab' line are principal type, -timestamp (in seconds since 1970), key version number (4), keytype (1 == -des), key length (always 8 with des), and then the key. - -To make the Heimdal KDC produce tickets that the Cisco can decode you -might have to turn on the @samp{encode_as_rep_as_tgs_rep} flag in the -KDC. You will also have to specify that the router can't handle anything -but @samp{des-cbc-crc}. This can be done with the @samp{del_enctype} -command of @samp{kadmin}. - -This all fine and so, but unless you have an IOS version with encryption -(available only in the U.S) it doesn't really solve any problems. Sure -you don't have to send your password over the wire, but since the telnet -connection isn't protected it's still possible for someone to steal your -session. This won't be fixed until someone adds integrity to the telnet -protocol. - -A working solution would be to hook up a machine with a real operating -system to the console of the Cisco and then use it as a backwards -terminal server. - -@section Making things work on Transarc AFS - -@subsection How to get a KeyFile - -@file{ktutil -k AFSKEYFILE:KeyFile get afs@@MY.REALM} |
