| 1076 | +.SH "DESCRIPTION"
|
---|
| 1077 | +.PP
|
---|
| 1078 | +\fBping\fR uses the ICMP protocol's mandatory ECHO_REQUEST
|
---|
| 1079 | +datagram to elicit an ICMP ECHO_RESPONSE from a host or gateway.
|
---|
| 1080 | +ECHO_REQUEST datagrams (``pings'') have an IP and ICMP
|
---|
| 1081 | +header, followed by a struct timeval and then an arbitrary
|
---|
| 1082 | +number of ``pad'' bytes used to fill out the packet.
|
---|
| 1083 | +.PP
|
---|
| 1084 | +\fBping6\fR is IPv6 version of \fBping\fR, and can also send Node Information Queries (RFC4620).
|
---|
| 1085 | +Intermediate \fIhop\fRs may not be allowed, because IPv6 source routing was deprecated (RFC5095).
|
---|
| 1086 | +.SH "OPTIONS"
|
---|
| 1087 | +.TP
|
---|
| 1088 | +\fB-a\fR
|
---|

|
---|
| 1090 | +.TP
|
---|
| 1091 | +\fB-A\fR
|
---|
| 1092 | +Adaptive ping. Interpacket interval adapts to round-trip time, so that
|
---|
| 1093 | +effectively not more than one (or more, if preload is set) unanswered probe
|
---|
| 1094 | +is present in the network. Minimal interval is 200msec for not super-user.
|
---|
| 1095 | +On networks with low rtt this mode is essentially equivalent to flood mode.
|
---|
| 1096 | +.TP

---|
| 1106 | +packets. With
|
---|
| 1107 | +\fIdeadline\fR

|
---|
| 1109 | +\fIcount\fR ECHO_REPLY packets, until the timeout expires.
|
---|
| 1110 | +.TP
|
---|
| 1111 | +\fB-d\fR
|
---|
| 1112 | +Set the SO_DEBUG option on the socket being used.

---|
| 1118 | +.TP
|
---|
| 1119 | +\fB-f\fR
|
---|
| 1120 | +Flood ping. For every ECHO_REQUEST sent a period ``.'' is printed,
|
---|
| 1121 | +while for ever ECHO_REPLY received a backspace is printed.
|
---|
| 1122 | +This provides a rapid display of how many packets are being dropped.
|
---|
| 1123 | +If interval is not given, it sets interval to zero and
|
---|
| 1124 | +outputs packets as fast as they come back or one hundred times per second,
|

|
---|
| 1138 | +The default is to wait for one second between each packet normally,

|
---|
| 1372 | +This program is intended for use in network testing, measurement and
|
---|
| 1373 | +management.
|
---|
| 1374 | +Because of the load it can impose on the network, it is unwise to use
|

| 1375 | +\fBping\fR during normal operations or from automated scripts.
|
---|
| 1376 | +.SH "ICMP PACKET DETAILS"
|
---|
| 1377 | +.PP
|
---|
| 1378 | +An IP header without options is 20 bytes.
|
---|
| 1379 | +An ICMP ECHO_REQUEST packet contains an additional 8 bytes worth
|
---|
| 1380 | +of ICMP header followed by an arbitrary amount of data.
|
---|
| 1381 | +When a \fIpacketsize\fR is given, this indicated the size of this
|
---|
| 1382 | +extra piece of data (the default is 56). Thus the amount of data received
|
---|
| 1383 | +inside of an IP packet of type ICMP ECHO_REPLY will always be 8 bytes
|
---|
| 1384 | +more than the requested data space (the ICMP header).
|
---|
| 1385 | +.PP
|
---|
| 1386 | +If the data space is at least of size of struct timeval
|
---|
| 1387 | +\fBping\fR uses the beginning bytes of this space to include
|
---|
| 1388 | +a timestamp which it uses in the computation of round trip times.
|
---|
| 1389 | +If the data space is shorter, no round trip times are given.
|
---|
| 1390 | +.SH "DUPLICATE AND DAMAGED PACKETS"
|
---|
| 1391 | +.PP
|
---|
| 1392 | +\fBping\fR will report duplicate and damaged packets.
|
---|
| 1393 | +Duplicate packets should never occur, and seem to be caused by
|
---|
| 1394 | +inappropriate link-level retransmissions.
|
---|
| 1395 | +Duplicates may occur in many situations and are rarely (if ever) a
|
---|
| 1396 | +good sign, although the presence of low levels of duplicates may not
|
---|
| 1397 | +always be cause for alarm.
|
---|
| 1398 | +.PP
|
---|
| 1399 | +Damaged packets are obviously serious cause for alarm and often
|
---|
| 1400 | +indicate broken hardware somewhere in the
|
---|
| 1401 | +\fBping\fR packet's path (in the network or in the hosts).
|
---|
| 1402 | +.SH "TRYING DIFFERENT DATA PATTERNS"
|
---|
| 1403 | +.PP
|
---|
| 1404 | +The (inter)network layer should never treat packets differently depending
|
---|
| 1405 | +on the data contained in the data portion.
|
---|
| 1406 | +Unfortunately, data-dependent problems have been known to sneak into
|
---|
| 1407 | +networks and remain undetected for long periods of time.
|
---|
| 1408 | +In many cases the particular pattern that will have problems is something
|
---|
| 1409 | +that doesn't have sufficient ``transitions'', such as all ones or all
|
---|
| 1410 | +zeros, or a pattern right at the edge, such as almost all zeros.
|
---|
| 1411 | +It isn't necessarily enough to specify a data pattern of all zeros (for
|
---|
| 1412 | +example) on the command line because the pattern that is of interest is
|
---|
| 1413 | +at the data link level, and the relationship between what you type and
|
---|
| 1414 | +what the controllers transmit can be complicated.
|
---|
| 1415 | +.PP
|
---|
| 1416 | +This means that if you have a data-dependent problem you will probably
|
---|
| 1417 | +have to do a lot of testing to find it.
|
---|
| 1418 | +If you are lucky, you may manage to find a file that either can't be sent
|
---|
| 1419 | +across your network or that takes much longer to transfer than other
|
---|
| 1420 | +similar length files.
|
---|
| 1421 | +You can then examine this file for repeated patterns that you can test
|
---|
| 1422 | +using the \fB-p\fR option of \fBping\fR.
|
---|
| 1423 | +.SH "TTL DETAILS"
|
---|
| 1424 | +.PP
|
---|
| 1425 | +The TTL value of an IP packet represents the maximum number of IP routers
|
---|
| 1426 | +that the packet can go through before being thrown away.
|
---|
| 1427 | +In current practice you can expect each router in the Internet to decrement
|
---|
| 1428 | +the TTL field by exactly one.
|
---|
| 1429 | +.PP
|
---|
| 1430 | +The TCP/IP specification states that the TTL field for TCP
|
---|
| 1431 | +packets should be set to 60, but many systems use smaller values
|
---|
| 1432 | +(4.3 BSD uses 30, 4.2 used 15).
|
---|
| 1433 | +.PP
|
---|
| 1434 | +The maximum possible value of this field is 255, and most Unix systems set
|
---|
| 1435 | +the TTL field of ICMP ECHO_REQUEST packets to 255.
|
---|
| 1436 | +This is why you will find you can ``ping'' some hosts, but not reach them
|
---|
| 1437 | +with
|
---|
| 1438 | +\fBtelnet\fR(1)
|
---|
| 1439 | +or
|
---|
| 1440 | +\fBftp\fR(1).
|
---|
| 1441 | +.PP
|
---|
| 1442 | +In normal operation ping prints the TTL value from the packet it receives.
|
---|
| 1443 | +When a remote system receives a ping packet, it can do one of three things
|
---|
| 1444 | +with the TTL field in its response:
|
---|
| 1445 | +.TP 0.2i
|
---|
| 1446 | +\(bu
|
---|
| 1447 | +Not change it; this is what Berkeley Unix systems did before the
|
---|
| 1448 | +4.3BSD Tahoe release. In this case the TTL value in the received packet
|
---|
| 1449 | +will be 255 minus the number of routers in the round-trip path.
|
---|
| 1450 | +.TP 0.2i
|
---|
| 1451 | +\(bu
|
---|
| 1452 | +Set it to 255; this is what current Berkeley Unix systems do.
|
---|
| 1453 | +In this case the TTL value in the received packet will be 255 minus the
|
---|
| 1454 | +number of routers in the path \fBfrom\fR
|
---|
| 1455 | +the remote system \fBto\fR the \fBping\fRing host.
|
---|
| 1456 | +.TP 0.2i
|
---|
| 1457 | +\(bu
|
---|
| 1458 | +Set it to some other value. Some machines use the same value for
|
---|
| 1459 | +ICMP packets that they use for TCP packets, for example either 30 or 60.
|
---|
| 1460 | +Others may use completely wild values.
|
---|

| 7199 | +.PP
|

|
---|
| 7311 | +.SH "DESCRIPTION"
|
---|
| 7312 | +.PP
|
---|
| 7313 | +\fBtftpd\fR is a server which supports the DARPA
|
---|
| 7314 | +Trivial File Transfer Protocol
|
---|
| 7315 | +(RFC1350).
|
---|
| 7316 | +The TFTP server is started
|
---|
| 7317 | +by \fBinetd\fR(8).
|
---|
| 7318 | +.PP
|
---|
| 7319 | +\fIdirectory\fR is required argument; if it is not given
|
---|
| 7320 | +\fBtftpd\fR aborts. This path is prepended to any file name requested
|
---|
| 7321 | +via TFTP protocol, effectively chrooting \fBtftpd\fR to this directory.
|
---|
| 7322 | +File names are validated not to escape out of this directory, however
|
---|
| 7323 | +administrator may configure such escape using symbolic links.
|
---|
| 7324 | +.PP
|
---|
| 7325 | +It is in difference of variants of \fBtftpd\fR usually distributed
|
---|
| 7326 | +with unix-like systems, which take a list of directories and match
|
---|
| 7327 | +file names to start from one of given prefixes or to some random
|
---|
| 7328 | +default, when no arguments were given. There are two reasons not to
|
---|
| 7329 | +behave in this way: first, it is inconvenient, clients are not expected
|
---|
| 7330 | +to know something about layout of filesystem on server host.
|
---|
| 7331 | +And second, TFTP protocol is not a tool for browsing of server's filesystem,
|
---|
| 7332 | +it is just an agent allowing to boot dumb clients.
|
---|
| 7333 | +.PP
|
---|
| 7334 | +In the case when \fBtftpd\fR is used together with
|
---|
| 7335 | +\fBrarpd\fR(8),
|
---|
| 7336 | +tftp directories in these services should coincide and it is expected
|
---|
| 7337 | +that each client booted via TFTP has boot image corresponding
|
---|
| 7338 | +its IP address with an architecture suffix following Sun Microsystems
|
---|
| 7339 | +conventions. See
|
---|
| 7340 | +\fBrarpd\fR(8)
|
---|
| 7341 | +for more details.
|
---|
| 7342 | +.SH "SECURITY"
|
---|
| 7343 | +.PP
|
---|
| 7344 | +TFTP protocol does not provide any authentication.
|
---|
| 7345 | +Due to this capital flaw \fBtftpd\fR is not able to restrict
|
---|
| 7346 | +access to files and will allow only publically readable
|
---|
| 7347 | +files to be accessed. Files may be written only if they already
|
---|
| 7348 | +exist and are publically writable.
|
---|
| 7349 | +.PP
|
---|
| 7350 | +Impact is evident, directory exported via TFTP \fBmust not\fR
|
---|
| 7351 | +contain sensitive information of any kind, everyone is allowed
|
---|
| 7352 | +to read it as soon as a client is allowed. Boot images do not contain
|
---|
| 7353 | +such information as rule, however you should think twice before
|
---|
| 7354 | +publishing f.e. Cisco IOS config files via TFTP, they contain
|
---|
| 7355 | +\fBunencrypted\fR passwords and may contain some information
|
---|
| 7356 | +about the network, which you were not going to make public.
|
---|
| 7357 | +.PP
|
---|
| 7358 | +The \fBtftpd\fR server should be executed by \fBinetd\fR
|
---|
| 7359 | +with dropped root privileges, namely with a user ID giving minimal
|
---|
| 7360 | +access to files published in tftp directory. If it is executed
|
---|
| 7361 | +as superuser occasionally, \fBtftpd\fR drops its UID and GID
|
---|
| 7362 | +to 65534, which is most likely not the thing which you expect.
|
---|
| 7363 | +However, this is not very essential; remember, only files accessible
|
---|
| 7364 | +for everyone can be read or written via TFTP.

| 7373 | +is cleaned up both syntactically (ANSIized) and semantically (UDP socket IO).
|
---|
| 7374 | +.PP
|
---|
| 7375 | +It is distributed with iputils mostly as good demo of an interesting feature
|
---|
| 7376 | +(MSG_CONFIRM) allowing to boot long images by dumb clients
|
---|
| 7377 | +not answering ARP requests until they are finally booted.

|
---|
| 7548 | +is Van Jacobson and it first appeared in 1988. This clone is
|
---|
| 7549 | +based on a port of \fBtraceroute\fR to IPv6 published
|
---|
| 7550 | +in NRL IPv6 distribution in 1996. In turn, it was ported
|
---|
| 7551 | +to Linux by Pedro Roque. After this it was kept in sync by
|
---|
| 7552 | +Alexey Kuznetsov
|
---|
| 7553 | +<kuznet@ms2.inr.ac.ru>. And eventually entered
|
---|
