|  | 1316 | +In current practice you can expect each router in the Internet to decrement | 
|---|
|  | 1317 | +the TTL field by exactly one. | 
|---|
|  | 1318 | +.PP | 
|---|
|  | 1319 | +The TCP/IP specification states that the TTL field for TCP | 
|---|
|  | 1320 | +packets should be set to 60, but many systems use smaller values | 
|---|
|  | 1321 | +(4.3 BSD uses 30, 4.2 used 15). | 
|---|
|  | 1322 | +.PP | 
|---|
|  | 1323 | +The maximum possible value of this field is 255, and most Unix systems set | 
|---|
|  | 1324 | +the TTL field of ICMP ECHO_REQUEST packets to 255. | 
|---|
|  | 1325 | +This is why you will find you can ``ping'' some hosts, but not reach them | 
|---|
|  | 1326 | +with | 
|---|
|  | 1327 | +\fBtelnet\fR(1) | 
|---|
|  | 1328 | +or | 
|---|
|  | 1329 | +\fBftp\fR(1). | 
|---|
|  | 1330 | +.PP | 
|---|
|  | 1331 | +In normal operation ping prints the ttl value from the packet it receives. | 
|---|
|  | 1332 | +When a remote system receives a ping packet, it can do one of three things | 
|---|
|  | 1333 | +with the TTL field in its response: | 
|---|
|  | 1334 | +.TP 0.2i | 
|---|
|  | 1335 | +\(bu | 
|---|
|  | 1336 | +Not change it; this is what Berkeley Unix systems did before the | 
|---|
|  | 1337 | +4.3BSD Tahoe release. In this case the TTL value in the received packet | 
|---|
|  | 1338 | +will be 255 minus the number of routers in the round-trip path. | 
|---|
|  | 1339 | +.TP 0.2i | 
|---|
|  | 1340 | +\(bu | 
|---|
|  | 1341 | +Set it to 255; this is what current Berkeley Unix systems do. | 
|---|
|  | 1342 | +In this case the TTL value in the received packet will be 255 minus the | 
|---|
|  | 1343 | +number of routers in the path \fBfrom\fR | 
|---|
|  | 1344 | +the remote system \fBto\fR the \fBping\fRing host. | 
|---|
|  | 1345 | +.TP 0.2i | 
|---|
|  | 1346 | +\(bu | 
|---|
|  | 1347 | +Set it to some other value. Some machines use the same value for | 
|---|
|  | 1348 | +ICMP packets that they use for TCP packets, for example either 30 or 60. | 
|---|
|  | 1349 | +Others may use completely wild values. |

|  | 6651 | +.SH "DESCRIPTION" | 
|---|
|  | 6652 | +.PP | 
|---|
|  | 6653 | +\fBtftpd\fR is a server which supports the DARPA | 
|---|
|  | 6654 | +Trivial File Transfer Protocol | 
|---|
|  | 6655 | +(RFC1350). | 
|---|
|  | 6656 | +The TFTP server is started | 
|---|
|  | 6657 | +by \fBinetd\fR(8). | 
|---|
|  | 6658 | +.PP | 
|---|
|  | 6659 | +\fIdirectory\fR is required argument; if it is not given | 
|---|
|  | 6660 | +\fBtftpd\fR aborts. This path is prepended to any file name requested | 
|---|
|  | 6661 | +via TFTP protocol, effectively chrooting \fBtftpd\fR to this directory. | 
|---|
|  | 6662 | +File names are validated not to escape out of this directory, however | 
|---|
|  | 6663 | +administrator may configure such escape using symbolic links. | 
|---|
|  | 6664 | +.PP | 
|---|
|  | 6665 | +It is in difference of variants of \fBtftpd\fR usually distributed | 
|---|
|  | 6666 | +with unix-like systems, which take a list of directories and match | 
|---|
|  | 6667 | +file names to start from one of given prefixes or to some random | 
|---|
|  | 6668 | +default, when no arguments were given. There are two reasons not to | 
|---|
|  | 6669 | +behave in this way: first, it is inconvenient, clients are not expected | 
|---|
|  | 6670 | +to know something about layout of filesystem on server host. | 
|---|
|  | 6671 | +And second, TFTP protocol is not a tool for browsing of server's filesystem, | 
|---|
|  | 6672 | +it is just an agent allowing to boot dumb clients. | 
|---|
|  | 6673 | +.PP | 
|---|
|  | 6674 | +In the case when \fBtftpd\fR is used together with | 
|---|
|  | 6675 | +\fBrarpd\fR(8), | 
|---|
|  | 6676 | +tftp directories in these services should coincide and it is expected | 
|---|
|  | 6677 | +that each client booted via TFTP has boot image corresponding | 
|---|
|  | 6678 | +its IP address with an architecture suffix following Sun Microsystems | 
|---|
|  | 6679 | +conventions. See | 
|---|
|  | 6680 | +\fBrarpd\fR(8) | 
|---|
|  | 6681 | +for more details. | 
|---|
|  | 6682 | +.SH "SECURITY" | 
|---|
|  | 6683 | +.PP | 
|---|
|  | 6684 | +TFTP protocol does not provide any authentication. | 
|---|
|  | 6685 | +Due to this capital flaw \fBtftpd\fR is not able to restrict | 
|---|
|  | 6686 | +access to files and will allow only publically readable | 
|---|
|  | 6687 | +files to be accessed. Files may be written only if they already | 
|---|
|  | 6688 | +exist and are publically writable. | 
|---|
|  | 6689 | +.PP | 
|---|
|  | 6690 | +Impact is evident, directory exported via TFTP \fBmust not\fR | 
|---|
|  | 6691 | +contain sensitive information of any kind, everyone is allowed | 
|---|
|  | 6692 | +to read it as soon as a client is allowed. Boot images do not contain | 
|---|
|  | 6693 | +such information as rule, however you should think twice before | 
|---|
|  | 6694 | +publishing f.e. Cisco IOS config files via TFTP, they contain | 
|---|
|  | 6695 | +\fBunencrypted\fR passwords and may contain some information | 
|---|
|  | 6696 | +about the network, which you were not going to make public. | 
|---|
|  | 6697 | +.PP | 
|---|
|  | 6698 | +The \fBtftpd\fR server should be executed by \fBinetd\fR | 
|---|
|  | 6699 | +with dropped root privileges, namely with a user ID giving minimal | 
|---|
|  | 6700 | +access to files published in tftp directory. If it is executed | 
|---|
|  | 6701 | +as superuser occasionally, \fBtftpd\fR drops its UID and GID | 
|---|
|  | 6702 | +to 65534, which is most likely not the thing which you expect. | 
|---|
|  | 6703 | +However, this is not very essential; remember, only files accessible | 
|---|
|  | 6704 | +for everyone can be read or written via TFTP. |
