0034 /* Define a default password for telnetd here.
0035  * NOTES:
0036  *  - this can be overridden at run-time by setting
0037  *    the "TELNETD_PASSWD" environment variable.
0038  *    As soon as that variable is set, the new password
0039  *    is effective - no need to restart telnetd.
0040  *  - this must be set to an _encrypted_ password, NOT
0041  *    the cleartext. Use the 'genpw' utility to generate
0042  *    a password string:
0043  *
0044  *    1) Compile 'genpw.c' for the HOST, i.e.
0045  *         cc -o genpw genpw.c -lcrypt
0046  *    1) delete an old password definition from this file.
0047  *    2) run './genpw >> passwd.h'. This will append
0048  *       a new definition to this file.
0049  *
0050  *  - if no password is defined here, no authentication
0051  *    is needed, i.e. telnet is open to the world.
