|  | 711 | +.PP | 
|---|
|  | 712 | +An IP header without options is 20 bytes. | 
|---|
|  | 713 | +An ICMP ECHO_REQUEST packet contains an additional 8 bytes worth | 
|---|
|  | 714 | +of ICMP header followed by an arbitrary amount of data. | 
|---|
|  | 715 | +When a \fIpacketsize\fR is given, this indicated the size of this | 
|---|
|  | 716 | +extra piece of data (the default is 56). Thus the amount of data received | 
|---|
|  | 717 | +inside of an IP packet of type ICMP ECHO_REPLY will always be 8 bytes | 
|---|
|  | 718 | +more than the requested data space (the ICMP header). | 
|---|
|  | 719 | +.PP | 
|---|
|  | 720 | +If the data space is at least of size of struct timeval | 
|---|
|  | 721 | +\fBping\fR uses the beginning bytes of this space to include | 
|---|
|  | 722 | +a timestamp which it uses in the computation of round trip times. | 
|---|
|  | 723 | +If the data space is shorter, no round trip times are given. |

|  | 724 | +.SH "DUPLICATE AND DAMAGED PACKETS" | 
|---|
|  | 725 | +.PP | 
|---|
|  | 726 | +\fBping\fR will report duplicate and damaged packets. | 
|---|
|  | 727 | +Duplicate packets should never occur, and seem to be caused by | 
|---|
|  | 728 | +inappropriate link-level retransmissions. | 
|---|
|  | 729 | +Duplicates may occur in many situations and are rarely (if ever) a | 
|---|
|  | 730 | +good sign, although the presence of low levels of duplicates may not | 
|---|
|  | 731 | +always be cause for alarm. | 
|---|
|  | 732 | +.PP | 
|---|
|  | 733 | +Damaged packets are obviously serious cause for alarm and often | 
|---|
|  | 734 | +indicate broken hardware somewhere in the | 
|---|
|  | 735 | +\fBping\fR packet's path (in the network or in the hosts). | 
|---|
|  | 736 | +.SH "TRYING DIFFERENT DATA PATTERNS" | 
|---|
|  | 737 | +.PP | 
|---|
|  | 738 | +The (inter)network layer should never treat packets differently depending | 
|---|
|  | 739 | +on the data contained in the data portion. | 
|---|
|  | 740 | +Unfortunately, data-dependent problems have been known to sneak into | 
|---|
|  | 741 | +networks and remain undetected for long periods of time. | 
|---|
|  | 742 | +In many cases the particular pattern that will have problems is something | 
|---|
|  | 743 | +that doesn't have sufficient ``transitions'', such as all ones or all | 
|---|
|  | 744 | +zeros, or a pattern right at the edge, such as almost all zeros. | 
|---|
|  | 745 | +It isn't necessarily enough to specify a data pattern of all zeros (for | 
|---|
|  | 746 | +example) on the command line because the pattern that is of interest is | 
|---|
|  | 747 | +at the data link level, and the relationship between what you type and | 
|---|
|  | 748 | +what the controllers transmit can be complicated. | 
|---|
|  | 749 | +.PP | 
|---|
|  | 750 | +This means that if you have a data-dependent problem you will probably | 
|---|
|  | 751 | +have to do a lot of testing to find it. | 
|---|
|  | 752 | +If you are lucky, you may manage to find a file that either can't be sent | 
|---|
|  | 753 | +across your network or that takes much longer to transfer than other | 
|---|
|  | 754 | +similar length files. | 
|---|
|  | 755 | +You can then examine this file for repeated patterns that you can test | 
|---|
|  | 756 | +using the \fB-p\fR option of \fBping\fR. | 
|---|
|  | 757 | +.SH "TTL DETAILS" | 
|---|
|  | 758 | +.PP | 
|---|
|  | 759 | +The TTL value of an IP packet represents the maximum number of IP routers | 
|---|
|  | 760 | +that the packet can go through before being thrown away. | 
|---|
|  | 761 | +In current practice you can expect each router in the Internet to decrement | 
|---|
|  | 762 | +the TTL field by exactly one. | 
|---|
|  | 763 | +.PP | 
|---|
|  | 764 | +The TCP/IP specification states that the TTL field for TCP | 
|---|
|  | 765 | +packets should be set to 60, but many systems use smaller values | 
|---|
|  | 766 | +(4.3 BSD uses 30, 4.2 used 15). | 
|---|
|  | 767 | +.PP | 
|---|
|  | 768 | +The maximum possible value of this field is 255, and most Unix systems set | 
|---|
|  | 769 | +the TTL field of ICMP ECHO_REQUEST packets to 255. | 
|---|
|  | 770 | +This is why you will find you can ``ping'' some hosts, but not reach them | 
|---|
|  | 771 | +with | 
|---|
|  | 772 | +\fBtelnet\fR(1) |

|  | 774 | +\fBftp\fR(1). | 
|---|
|  | 775 | +.PP | 
|---|
|  | 776 | +In normal operation ping prints the TTL value from the packet it receives. | 
|---|
|  | 777 | +When a remote system receives a ping packet, it can do one of three things | 
|---|

|  | 783 | +will be 255 minus the number of routers in the round-trip path. |

|---|
|  | 936 | +\fBrdisc\fR implements client side of the ICMP router discover protocol. | 
|---|
|  | 937 | +\fBrdisc\fR is invoked at boot time to populate the network | 
|---|
|  | 938 | +routing tables with default routes. | 
|---|
|  | 939 | +.PP | 
|---|
|  | 940 | +\fBrdisc\fR listens on the ALL_HOSTS (224.0.0.1) multicast address | 
|---|
|  | 941 | +(or \fIreceive_address\fR provided it is given) | 
|---|
|  | 942 | +for ROUTER_ADVERTISE messages from routers. The received | 
|---|
|  | 943 | +messages are handled by first ignoring those listed router addresses | 
|---|
|  | 944 | +with which the host does not share a network. Among the remaining addresses | 
|---|
|  | 945 | +the ones with the highest preference are selected as default routers | 
|---|
|  | 946 | +and a default route is entered in the kernel routing table | 
|---|
|  | 947 | +for each one of them. | 
|---|
|  | 948 | +.PP | 
|---|
|  | 949 | +Optionally, \fBrdisc\fR can avoid waiting for routers to announce | 
|---|
|  | 950 | +themselves by sending out a few ROUTER_SOLICITATION messages | 
|---|
|  | 951 | +to the ALL_ROUTERS (224.0.0.2) multicast address |

|---|
|  | 953 | +when it is started. | 
|---|
|  | 954 | +.PP | 
|---|
|  | 955 | +A timer is associated with each router address and the address will | 
|---|
|  | 956 | +no longer be considered for inclusion in the the routing tables if the | 
|---|
|  | 957 | +timer expires before a new | 
|---|
|  | 958 | +\fBadvertise\fR message is received from the router. | 
|---|
|  | 959 | +The address will also be excluded from consideration if the host receives an | 
|---|
|  | 960 | +\fBadvertise\fR | 
|---|
|  | 961 | +message with the preference being maximally negative. | 
|---|
|  | 962 | +.PP | 
|---|
|  | 963 | +Server side of router discovery protocol is supported by Cisco IOS | 
|---|
|  | 964 | +and by any more or less complete UNIX routing daemon, f.e \fBgated\fR. |

|---|
|  | 1061 | +.PP | 
|---|
|  | 1062 | +\fBtftpd\fR is a server which supports the DARPA | 
|---|
|  | 1063 | +Trivial File Transfer Protocol | 
|---|
|  | 1064 | +(RFC1350). | 
|---|
|  | 1065 | +The TFTP server is started | 
|---|
|  | 1066 | +by \fBinetd\fR(8). | 
|---|
|  | 1067 | +.PP | 
|---|
|  | 1068 | +\fIdirectory\fR is required argument; if it is not given | 
|---|
|  | 1069 | +\fBtftpd\fR aborts. This path is prepended to any file name requested | 
|---|
|  | 1070 | +via TFTP protocol, effectively chrooting \fBtftpd\fR to this directory. | 
|---|
|  | 1071 | +File names are validated not to escape out of this directory, however | 
|---|
|  | 1072 | +administrator may configure such escape using symbolic links. | 
|---|
|  | 1073 | +.PP | 
|---|
|  | 1074 | +It is in difference of variants of \fBtftpd\fR usually distributed | 
|---|
|  | 1075 | +with unix-like systems, which take a list of directories and match | 
|---|
|  | 1076 | +file names to start from one of given prefixes or to some random | 
|---|
|  | 1077 | +default, when no arguments were given. There are two reasons not to | 
|---|
|  | 1078 | +behave in this way: first, it is inconvenient, clients are not expected | 
|---|
|  | 1079 | +to know something about layout of filesystem on server host. | 
|---|
|  | 1080 | +And second, TFTP protocol is not a tool for browsing of server's filesystem, | 
|---|
|  | 1081 | +it is just an agent allowing to boot dumb clients. | 
|---|
|  | 1082 | +.PP | 
|---|
|  | 1083 | +In the case when \fBtftpd\fR is used together with | 
|---|
|  | 1084 | +\fBrarpd\fR(8), | 
|---|
|  | 1085 | +tftp directories in these services should coincide and it is expected | 
|---|
|  | 1086 | +that each client booted via TFTP has boot image corresponding | 
|---|
|  | 1087 | +its IP address with an architecture suffix following Sun Microsystems | 
|---|
|  | 1088 | +conventions. See | 
|---|
|  | 1089 | +\fBrarpd\fR(8) | 
|---|
|  | 1090 | +for more details. | 
|---|
|  | 1091 | +.SH "SECURITY" | 
|---|
|  | 1092 | +.PP | 
|---|
|  | 1093 | +TFTP protocol does not provide any authentication. | 
|---|
|  | 1094 | +Due to this capital flaw \fBtftpd\fR is not able to restrict | 
|---|
|  | 1095 | +access to files and will allow only publically readable | 
|---|
|  | 1096 | +files to be accessed. Files may be written only if they already | 
|---|
|  | 1097 | +exist and are publically writable. | 
|---|
|  | 1098 | +.PP | 
|---|
|  | 1099 | +Impact is evident, directory exported via TFTP \fBmust not\fR | 
|---|
|  | 1100 | +contain sensitive information of any kind, everyone is allowed | 
|---|
|  | 1101 | +to read it as soon as a client is allowed. Boot images do not contain | 
|---|
|  | 1102 | +such information as rule, however you should think twice before | 
|---|
|  | 1103 | +publishing f.e. Cisco IOS config files via TFTP, they contain | 
|---|
|  | 1104 | +\fBunencrypted\fR passwords and may contain some information | 
|---|
|  | 1105 | +about the network, which you were not going to make public. | 
|---|
|  | 1106 | +.PP | 
|---|
|  | 1107 | +The \fBtftpd\fR server should be executed by \fBinetd\fR | 
|---|
|  | 1108 | +with dropped root privileges, namely with a user ID giving minimal | 
|---|
|  | 1109 | +access to files published in tftp directory. If it is executed | 
|---|
|  | 1110 | +as superuser occasionally, \fBtftpd\fR drops its UID and GID | 
|---|
|  | 1111 | +to 65534, which is most likely not the thing which you expect. | 
|---|
|  | 1112 | +However, this is not very essential; remember, only files accessible |

|  | 1209 | +F.e. the third line shows asymmetry of 1, it is because the first probe |

|  | 1271 | +is Van Jacobson and it first appeared in 1988. This clone is | 
|---|
|  | 1272 | +based on a port of \fBtraceroute\fR to IPv6 published | 
|---|
|  | 1273 | +in NRL IPv6 distribution in 1996. In turn, it was ported | 
|---|
|  | 1274 | +to Linux by Pedro Roque. After this it was kept in sync by | 
|---|
|  | 1275 | +Alexey Kuznetsov | 
|---|
|  | 1276 | +<kuznet@ms2.inr.ac.ru>. And eventually entered |
