Table 24-4 TACACS+: Daemon Does Not Run
Possible Problem Solution
TACACS+ has not been
launched
Launch TACACS+ with the command tac_plus -C configuration filename.
TACACS+ not specified in
/etc/services file
Step 1 Check the /etc/services file for the following line:
tacacs 49/tcp
Step 2
This line must be included in the file. If the line is not present, add the line
to the file.
tac_plus executable does not
exist
The TACACS+ daemon cannot run if the tac_plus executable does not exist.
Step 1 Check the directory where you installed tac_plus.2.1 to see whether the
tac_plus file exists.
Step 2 If the file does not exist, use the make tac_plus command to compile
tac_plus.
Possible Problem Solution
TACACS+ configuration file
not present
Step 1 Check the directory in which you installed TACACS+ for a configuration
file in the TACACS+ format.
Step 2 If there is no TACACS+ configuration file present and you are upgrading
from XTACACS, convert your password file into a configuration file by
issuing the following command:
unix_host% convert.pl /etc/passwd > configuration-file
Step 3 If there is no TACACS+ configuration file present, create one using a text
editor. At a minimum, the configuration file must contain the following
text:
user = userid {
login = cleartext “passwd”
}
The configuration file can have any name you want.
For more information, refer to the user guide located in the tac_plus.2.1
directory.
