43 | .Nm tftpd | |
44 | .Op Ar directory ... | |
45 | .Sh DESCRIPTION | |
46 | .Nm Tftpd | |
47 | is a server which supports the | |
48 | .Tn DARPA | |
49 | Trivial File Transfer | |
50 | Protocol. | |
51 | The | |
52 | .Tn TFTP | |
53 | server operates | |
54 | at the port indicated in the | |
55 | .Ql tftp | |
56 | service description; | |
57 | see | |
58 | .Xr services 5 . | |
59 | The server is normally started by | |
60 | .Xr inetd 8 . | |
61 | .Pp | |
62 | The use of | |
63 | .Xr tftp 1 | |
64 | does not require an account or password on the remote system. | |
65 | Due to the lack of authentication information, | |
66 | .Nm tftpd | |
67 | will allow only publicly readable files to be | |
68 | accessed. | |
69 | Files may be written only if they already exist and are publicly writable. | |
70 | Note that this extends the concept of | |
71 | .Dq public | |
72 | to include | |
73 | all users on all hosts that can be reached through the network; | |
74 | this may not be appropriate on all systems, and its implications | |
75 | should be considered before enabling tftp service. | |
76 | The server should have the user ID with the lowest possible privilege. | |
77 | .Pp | |
78 | Access to files may be restricted by invoking | |
79 | .Nm tftpd | |
80 | with a list of directories by including pathnames | |
81 | as server program arguments in | |
82 | .Pa /etc/inetd.conf . | |
83 | In this case access is restricted to files whose | |
84 | names are prefixed by the one of the given directories. | |
