>Description:
ftp prints garbage when I type Control-D at the login prompt.
>How-To-Repeat:
hal9000: 0 $ ftp localhost
Connected to localhost.
220 hal9000.details.de FTP server (Version 6.00) ready.
Name (localhost:schweikh): ^D331 Password required for .
The garbage is the stuff after 'Password required for '
>Fix:
The bug is that tmp[] is used unitialized when fgets returns NULL.
The following patch to usr.bin/ftp/ftp.c makes a Control-D at the
login prompt leave ftp -- the same behavior as for telnet.
