BOS_LISTKEYS(8) AFS Command Reference BOS_LISTKEYS(8)NAMEbos_listkeys - Displays the server encryption keys from the KeyFile
file
SYNOPSIS
bos listkeys -server <machine name> [-showkey]
[-cell <cell name>] [-noauth] [-localauth] [-help]
bos listk -se <machine name> [-sh] [-c <cell name>]
[-n] [-l] [-h]
DESCRIPTION
The bos listkeys command formats and displays the list of server
encryption keys from the /usr/afs/etc/KeyFile file on the server
machine named by the -server argument. It is equivalent to asetkey
list, but can be run remotely.
To edit the list of keys, use the asetkey command; see asetkey(8) for
more information. You can also remove keys remotely using the bos
removekey command. If you are using the Authentication Server
(kaserver) rather than a Kerberos v5 KDC, use the bos addkey command
instead of asetkey to add a new key.
CAUTIONS
Displaying actual keys on the standard output stream (by including the
-showkey flag) is a security exposure. Displaying a checksum is
sufficient for most purposes.
OPTIONS-server <machine name>
Indicates the server machine from which to display the KeyFile
file. Identify the machine by IP address or its host name (either
fully-qualified or abbreviated unambiguously). For details, see
bos(8).
For consistent performance in the cell, the output must be the same
on every server machine. asetkey(8) explains how to keep the
machines synchronized.
-showkey
Displays the octal digits that constitute each key. Anyone who has
access to the resulting output will have complete access to the AFS
cell and will be able to impersonate the AFS cell to any client, so
be very careful when using this option.
-cell <cell name>
Names the cell in which to run the command. Do not combine this
argument with the -localauth flag. For more details, see bos(8).
-noauth
Assigns the unprivileged identity "anonymous" to the issuer. Do not
combine this flag with the -localauth flag. For more details, see
bos(8).
-localauth
Constructs a server ticket using a key from the local
/usr/afs/etc/KeyFile file. The bos command interpreter presents the
ticket to the BOS Server during mutual authentication. Do not
combine this flag with the -cell or -noauth options. For more
details, see bos(8).
-help
Prints the online help for this command. All other valid options
are ignored.
OUTPUT
The output includes one line for each server encryption key listed in
the KeyFile file, identified by its key version number.
If the -showkey flag is included, the output displays the actual string
of eight octal numbers that constitute the key. Each octal number is a
backslash and three decimal digits.
If the -showkey flag is not included, the output represents each key as
a checksum, which is a decimal number derived by encrypting a constant
with the key.
Following the list of keys or checksums, the string "Keys last changed"
indicates when a key was last added to the KeyFile file. The words "All
done" indicate the end of the output.
For mutual authentication to work properly, the output from the command
"kas examine afs" must match the key or checksum with the same key
version number in the output from this command.
EXAMPLES
The following example shows the checksums for the keys stored in the
KeyFile file on the machine "fs3.abc.com".
% bos listkeys fs3.abc.com
key 1 has cksum 972037177
key 3 has cksum 2825175022
key 4 has cksum 260617746
key 6 has cksum 4178774593
Keys last changed on Mon Apr 12 11:24:46 1999.
All done.
The following example shows the actual keys from the KeyFile file on
the machine "fs6.abc.com".
% bos listkeys fs6.abc.com -showkey
key 0 is '\040\205\211\241\345\002\023\211'
key 1 is '\343\315\307\227\255\320\135\244'
key 2 is '\310\310\255\253\326\236\261\211'
Keys last changed on Wed Mar 31 11:24:46 1999.
All done.
PRIVILEGE REQUIRED
The issuer must be listed in the /usr/afs/etc/UserList file on the
machine named by the -server argument, or must be logged onto a server
machine as the local superuser "root" if the -localauth flag is
included.
