There are two authentication databases, one holding information about Plan 9 accounts and one holding SecureNet keys. A .I user need not be installed in both databases but must be installed in the Plan 9 database to connect to a Plan 9 service. .PP .I Changeuser installs or changes .I user in an authentication database. It does not install a user on a Plan 9 file server; see .IR fs (8) for that. .PP Option .B -p installs .I user in the Plan 9 database. .I Changeuser asks twice for a password for the new .IR user . If the responses do not match or the password is too easy to guess the .I user is not installed. .I Changeuser also asks for an APOP secret. This secret is used in the APOP (RFC1939), CRAM (RFC2195), and Microsoft challenge/response protocols used for POP3, IMAP, and VPN access. .PP Option .B -n installs .I user in the SecureNet database and prints out a key for the SecureNet box. The key is chosen by .IR changeuser . .PP If neither option .B -p or option .B -n is given, .I changeuser installs the .I user in the Plan 9 database. .PP .I Changeuser prompts for biographical information such as email address, user name, sponsor and department number and appends it to the file .B /adm/netkeys.who or .BR /adm/keys.who . .PP .I Convkeys re-encrypts the key file .IR keyfile . Re-encryption is performed in place. Without the .B -p option .I convkeys uses the key stored in NVRAM to decrypt the file, and encrypts it using the new key. By default, .I convkeys prompts twice for the new password. The .B -p forces .I convkeys to also prompt for the old password. The .B -a option converts the file into AES format. The format of .I keyfile is described in .IR keyfs (4). .PP .I Printnetkey displays the network key as it should be entered into the hand-held Securenet box. .PP .I Status is a shell script that prints out everything known about a user and the user's key status. .PP .I Enable/disable are shell scripts that enable/disable both the Plan 9 and Netkey keys for individual users. .PP .I Authsrv is the program, run only on the authentication server, that handles ticket requests on TCP port 567. It is started by an incoming call to the server requesting a conversation ticket; its standard input and output are the network connection. .I Authsrv executes the authentication server's end of the appropriate protocol as described in .IR authsrv (6). .PP .I Guard.srv is similar. It is called whenever a foreign (e.g. Unix) system wants to do a SecureNet challenge/response authentication. .SS Anywhere commands .PP The remaining commands need not be run on an authentication server. .PP .I Debug attempts to authenticate using each .B p9sk1 key found in .I factotum and prints progress reports. .PP .I Wrkey prompts for a machine key, host owner, and host domain and stores them in local non-volatile RAM. .PP .I Login allows a user to change his authenticated id to .IR user . .I Login sets up a new namespace from .BR /lib/namespace , starts a .IR factotum (4) under the new id and .IR exec s .IR rc (1) under the new id. .PP .I Newns sets up a new namespace from .I namespace (default .BR /lib/namespace ) and .IR exec s its arguments. If there are no arguments, it .IR exec s .BR /bin/rc . Under .BR -a , .I newns adds to the current namespace instead of constructing a new one. The .BR -d option enables debugging output. .PP .I None sets up a new namespace from .I namespace (default .BR /lib/namespace ) as the user .I none and .IR exec s its arguments under the new id. If there are no arguments, it .IR exec s .BR /bin/rc . It's an easy way to run a command as .IR none . .PP .I As executes .I command as .IR user . .I Command is a single argument to .IR rc , containing an arbitrary .I rc command. This only works for the hostowner and only if .L #¤/caphash still exists. .SH FILES .TF /adm/netkeys.who .TP .B /lib/ndb/auth Speaksfor relationships and mappings for RADIUS server id's. .TP .B /adm/keys.who List of users in the Plan 9 database. .TP .B /adm/netkeys.who List of users in the SecureNet database. .SH SOURCE .B /sys/src/cmd/auth .SH "SEE ALSO" .IR passwd (1), .I readnvram in .IR authsrv (2), .IR keyfs (4), .IR securenet (8) .SH BUGS Only CPU kernels permit changing userid.
