46 | .Sh DESCRIPTION | |
47 | .Nm Tftpd | |
48 | is a server which supports the | |
d43ab529 AC |
49 | Internet Trivial File Transfer |
50 | Protocol (\c | |
51 | .Tn RFC 783). | |
0fccfdb8 CL |
52 | The |
53 | .Tn TFTP | |
54 | server operates | |
55 | at the port indicated in the | |
56 | .Ql tftp | |
57 | service description; | |
9a0d3ce2 | 58 | see |
0fccfdb8 | 59 | .Xr services 5 . |
0a333f78 | 60 | The server is normally started by |
0fccfdb8 CL |
61 | .Xr inetd 8 . |
62 | .Pp | |
9a0d3ce2 | 63 | The use of |
0fccfdb8 | 64 | .Xr tftp 1 |
9a0d3ce2 KM |
65 | does not require an account or password on the remote system. |
66 | Due to the lack of authentication information, | |
0fccfdb8 | 67 | .Nm tftpd |
9a0d3ce2 KM |
68 | will allow only publicly readable files to be |
69 | accessed. | |
d43ab529 | 70 | Files containing the string ``/\|\fB.\|.\fP\|/'' are not allowed. |
0a333f78 | 71 | Files may be written only if they already exist and are publicly writable. |
0fccfdb8 CL |
72 | Note that this extends the concept of |
73 | .Dq public | |
74 | to include | |
9a0d3ce2 KM |
75 | all users on all hosts that can be reached through the network; |
76 | this may not be appropriate on all systems, and its implications | |
77 | should be considered before enabling tftp service. | |
0a333f78 | 78 | The server should have the user ID with the lowest possible privilege. |
0fccfdb8 | 79 | .Pp |
4d24819a | 80 | Access to files may be restricted by invoking |
0fccfdb8 | 81 | .Nm tftpd |
d43ab529 | 82 | with a list of directories by including up to 20 pathnames |
4d24819a | 83 | as server program arguments in |
0fccfdb8 | 84 | .Pa /etc/inetd.conf . |
4d24819a TF |
85 | In this case access is restricted to files whose |
86 | names are prefixed by the one of the given directories. | |
d43ab529 AC |
87 | The given directories are also treated as a search path for |
88 | relative filename requests. | |
89 | .Pp | |
90 | The options are: | |
91 | .Bl -tag -width Ds | |
92 | .It Fl l | |
93 | Logs all requests using | |
94 | .Xr syslog 3 . | |
95 | .It Fl n | |
96 | Suppresses negative acknowledgement of requests for nonexistent | |
97 | relative filenames. | |
