|---|
|  | 1439 | +An IP header without options is 20 bytes. | 
|---|
|  | 1440 | +An ICMP ECHO_REQUEST packet contains an additional 8 bytes worth | 
|---|
|  | 1441 | +of ICMP header followed by an arbitrary amount of data. | 
|---|
|  | 1442 | +When a \fIpacketsize\fR is given, this indicated the size of this | 
|---|
|  | 1443 | +extra piece of data (the default is 56). Thus the amount of data received | 
|---|
|  | 1444 | +inside of an IP packet of type ICMP ECHO_REPLY will always be 8 bytes | 
|---|
|  | 1445 | +more than the requested data space (the ICMP header). | 
|---|
|  | 1446 | +.PP | 
|---|
|  | 1447 | +If the data space is at least of size of struct timeval | 
|---|
|  | 1448 | +\fBping\fR uses the beginning bytes of this space to include |

|  | 1449 | +a timestamp which it uses in the computation of round trip times. |

|  | 1451 | +.SH "DUPLICATE AND DAMAGED PACKETS" | 
|---|
|  | 1452 | +.PP | 
|---|
|  | 1453 | +\fBping\fR will report duplicate and damaged packets. | 
|---|
|  | 1454 | +Duplicate packets should never occur, and seem to be caused by | 
|---|
|  | 1455 | +inappropriate link-level retransmissions. | 
|---|
|  | 1456 | +Duplicates may occur in many situations and are rarely (if ever) a | 
|---|
|  | 1457 | +good sign, although the presence of low levels of duplicates may not | 
|---|
|  | 1458 | +always be cause for alarm. | 
|---|
|  | 1459 | +.PP | 
|---|
|  | 1460 | +Damaged packets are obviously serious cause for alarm and often | 
|---|
|  | 1461 | +indicate broken hardware somewhere in the | 
|---|
|  | 1462 | +\fBping\fR packet's path (in the network or in the hosts). | 
|---|
|  | 1463 | +.SH "TRYING DIFFERENT DATA PATTERNS" | 
|---|
|  | 1464 | +.PP | 
|---|
|  | 1465 | +The (inter)network layer should never treat packets differently depending | 
|---|
|  | 1466 | +on the data contained in the data portion. | 
|---|
|  | 1467 | +Unfortunately, data-dependent problems have been known to sneak into | 
|---|
|  | 1468 | +networks and remain undetected for long periods of time. | 
|---|
|  | 1469 | +In many cases the particular pattern that will have problems is something | 
|---|
|  | 1470 | +that doesn't have sufficient ``transitions'', such as all ones or all | 
|---|
|  | 1471 | +zeros, or a pattern right at the edge, such as almost all zeros. | 
|---|
|  | 1472 | +It isn't necessarily enough to specify a data pattern of all zeros (for | 
|---|
|  | 1473 | +example) on the command line because the pattern that is of interest is | 
|---|
|  | 1474 | +at the data link level, and the relationship between what you type and | 
|---|
|  | 1475 | +what the controllers transmit can be complicated. | 
|---|
|  | 1476 | +.PP | 
|---|
|  | 1477 | +This means that if you have a data-dependent problem you will probably | 
|---|
|  | 1478 | +have to do a lot of testing to find it. | 
|---|
|  | 1479 | +If you are lucky, you may manage to find a file that either can't be sent | 
|---|
|  | 1480 | +across your network or that takes much longer to transfer than other | 
|---|
|  | 1481 | +similar length files. | 
|---|
|  | 1482 | +You can then examine this file for repeated patterns that you can test | 
|---|
|  | 1483 | +using the \fB-p\fR option of \fBping\fR. | 
|---|
|  | 1484 | +.SH "TTL DETAILS" | 
|---|
|  | 1485 | +.PP | 
|---|
|  | 1486 | +The TTL value of an IP packet represents the maximum number of IP routers | 
|---|
|  | 1487 | +that the packet can go through before being thrown away. | 
|---|
|  | 1488 | +In current practice you can expect each router in the Internet to decrement | 
|---|
|  | 1489 | +the TTL field by exactly one. | 
|---|
|  | 1490 | +.PP | 
|---|
|  | 1491 | +The TCP/IP specification states that the TTL field for TCP | 
|---|
|  | 1492 | +packets should be set to 60, but many systems use smaller values | 
|---|
|  | 1493 | +(4.3 BSD uses 30, 4.2 used 15). | 
|---|
|  | 1494 | +.PP | 
|---|
|  | 1495 | +The maximum possible value of this field is 255, and most Unix systems set | 
|---|
|  | 1496 | +the TTL field of ICMP ECHO_REQUEST packets to 255. | 
|---|
|  | 1497 | +This is why you will find you can ``ping'' some hosts, but not reach them | 
|---|
|  | 1498 | +with | 
|---|
|  | 1499 | +\fBtelnet\fR(1) |

|---|
|  | 7339 | +.SH "DESCRIPTION" | 
|---|
|  | 7340 | +.PP | 
|---|
|  | 7341 | +\fBtftpd\fR is a server which supports the DARPA | 
|---|
|  | 7342 | +Trivial File Transfer Protocol | 
|---|
|  | 7343 | +(RFC1350). | 
|---|
|  | 7344 | +The TFTP server is started | 
|---|
|  | 7345 | +by \fBinetd\fR(8). | 
|---|
|  | 7346 | +.PP | 
|---|
|  | 7347 | +\fIdirectory\fR is required argument; if it is not given | 
|---|
|  | 7348 | +\fBtftpd\fR aborts. This path is prepended to any file name requested | 
|---|
|  | 7349 | +via TFTP protocol, effectively chrooting \fBtftpd\fR to this directory. | 
|---|
|  | 7350 | +File names are validated not to escape out of this directory, however | 
|---|
|  | 7351 | +administrator may configure such escape using symbolic links. | 
|---|
|  | 7352 | +.PP | 
|---|
|  | 7353 | +It is in difference of variants of \fBtftpd\fR usually distributed | 
|---|
|  | 7354 | +with unix-like systems, which take a list of directories and match | 
|---|
|  | 7355 | +file names to start from one of given prefixes or to some random | 
|---|
|  | 7356 | +default, when no arguments were given. There are two reasons not to | 
|---|
|  | 7357 | +behave in this way: first, it is inconvenient, clients are not expected | 
|---|
|  | 7358 | +to know something about layout of filesystem on server host. | 
|---|
|  | 7359 | +And second, TFTP protocol is not a tool for browsing of server's filesystem, | 
|---|
|  | 7360 | +it is just an agent allowing to boot dumb clients. | 
|---|
|  | 7361 | +.PP | 
|---|
|  | 7362 | +In the case when \fBtftpd\fR is used together with | 
|---|
|  | 7363 | +\fBrarpd\fR(8), | 
|---|
|  | 7364 | +tftp directories in these services should coincide and it is expected | 
|---|
|  | 7365 | +that each client booted via TFTP has boot image corresponding | 
|---|
|  | 7366 | +its IP address with an architecture suffix following Sun Microsystems | 
|---|
|  | 7367 | +conventions. See | 
|---|
|  | 7368 | +\fBrarpd\fR(8) | 
|---|
|  | 7369 | +for more details. | 
|---|
|  | 7370 | +.SH "SECURITY" | 
|---|
|  | 7371 | +.PP | 
|---|
|  | 7372 | +TFTP protocol does not provide any authentication. | 
|---|
|  | 7373 | +Due to this capital flaw \fBtftpd\fR is not able to restrict | 
|---|
|  | 7374 | +access to files and will allow only publically readable | 
|---|
|  | 7375 | +files to be accessed. Files may be written only if they already | 
|---|
|  | 7376 | +exist and are publically writable. | 
|---|
|  | 7377 | +.PP | 
|---|
|  | 7378 | +Impact is evident, directory exported via TFTP \fBmust not\fR | 
|---|
|  | 7379 | +contain sensitive information of any kind, everyone is allowed | 
|---|
|  | 7380 | +to read it as soon as a client is allowed. Boot images do not contain | 
|---|
|  | 7381 | +such information as rule, however you should think twice before | 
|---|
|  | 7382 | +publishing f.e. Cisco IOS config files via TFTP, they contain | 
|---|
|  | 7383 | +\fBunencrypted\fR passwords and may contain some information | 
|---|
|  | 7384 | +about the network, which you were not going to make public. | 
|---|
|  | 7385 | +.PP | 
|---|
|  | 7386 | +The \fBtftpd\fR server should be executed by \fBinetd\fR | 
|---|
|  | 7387 | +with dropped root privileges, namely with a user ID giving minimal | 
|---|
|  | 7388 | +access to files published in tftp directory. If it is executed | 
|---|
|  | 7389 | +as superuser occasionally, \fBtftpd\fR drops its UID and GID | 
|---|
|  | 7390 | +to 65534, which is most likely not the thing which you expect. | 
|---|
|  | 7391 | +However, this is not very essential; remember, only files accessible | 
|---|
|  | 7392 | +for everyone can be read or written via TFTP. |

|---|
|  | 7545 | +This program has long history. Author of \fBtraceroute\fR | 
|---|
|  | 7546 | +is Van Jacobson and it first appeared in 1988. This clone is | 
|---|
|  | 7547 | +based on a port of \fBtraceroute\fR to IPv6 published | 
|---|
|  | 7548 | +in NRL IPv6 distribution in 1996. In turn, it was ported | 
|---|
|  | 7549 | +to Linux by Pedro Roque. After this it was kept in sync by | 
|---|
|  | 7550 | +Alexey Kuznetsov | 
|---|
|  | 7551 | +<kuznet@ms2.inr.ac.ru>. And eventually entered | 
|---|
|  | 7552 | +\fBiputils\fR package. | 
|---|
|  | 7553 | +.SH "SECURITY" | 
|---|
|  | 7554 | +.PP | 
|---|
|  | 7555 | +\fBtracepath6\fR requires CAP_NET_RAW capability | 
|---|
|  | 7556 | +to be executed. It is safe to be used as set-uid root. |
