The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

Each line displays the data rate associated with different classes of packets. .Pp .Nm understands the following command line options: .Bl -tag -width 12ex -offset indent .It Fl 1 Single-shot (batch) mode. .Nm collects data for .Ar waittime seconds (see .Fl w option) then emits a line indicating the number of flows detected, and the period of data capture in seconds. Then, each flow line is printed in the form of the number of data link octets associated with the flow, the number of data link frames (packets), and then the flow description. .It Fl a Ar abbrev Add .Ar abbrev to the list of abbreviation patterns. (See below for details.) .It Fl A Ar file Read abbreviation patterns from the given .Ar file . (See .Sx Abbreviations , below.) If the option .Fl A Ic none is given, then default abbreviation files are not loaded. .It Fl B Display data rates in bytes per second (Bps) instead of in bits per second (bps). .It Fl c Do not combine some packet classes into one class. For example, TCP connections are kept as two separate flows. .\" .It Fl E .\" Don't exit on errors from the .\" .Xr pcap 3 .\" library. .It Fl F Show full hostnames. Normally, hostnames are truncated to the first component of their domain name before display. .It Fl i Ar interface Listen on the given interface. If not specified, a suitable interface is chosen. .It Fl k Ar keeptime When no packets have been seen for a particular class, retain an entry on the display for this many screen seconds. Defaults to 10. .It Fl l Display and sort flows by when they were last seen. (Incompatible with .Fl t ) .It Fl m Ar maxbps Fix the maximum bit rate for the interface at .Ar maxbps instead of auto-detecting it. .It Fl n Do not try and resolve hostnames or service port numbers. .It Fl p Show packet counts instead of bit counts. .It Fl P Do not try to put the interface into promiscuous mode. .It Fl t "Top" mode. Sorts the display by bit count (or packet count if .Fl p was given) instead of by the name. .It Fl T Show totals. .It Fl w Ar waittime Refresh the display every .Ar waittime seconds. The default is 5 seconds. .It Ar filter-expr Only consider packets matching the given .Ar filter-expr . If no filter is provided, all packets are considered. See .Xr tcpdump 8 for information on valid expressions. .El .Pp If the terminal supports it, the display briefly highlights in bold new connections or old connections carrying data after a period of inactivity. .Pp Simple statistics about the interface are also displayed such as the current and average bit rates (measured just above the data link layer). Load averages refer to bit rate decayed averages for the last 1, 5 and 15 minutes. .Pp During display, the following keystrokes are recognised: .Bl -tag -width Ic -offset indent .It Ic q quit .It Ic Ctrl-L redraw screen .It Ic t toggle the .Fl t flag (top mode) .It Ic T toggle the .Fl T flag (totals mode) .It Ic w allows changing of the .Fl w flag value (wait time) .It Ic n toggle the .Fl n flag (numeric display) .It Ic p toggle the .Fl p flag (packets instead of bits) .It Ic b | B toggle the .Fl B flag (bps or Bps) .It Ic f | F toggle the .Fl F flag (full hostnames) .It Ic r reset collected statistics (min, max, etc.), flush flow history and reset DNS/service and fragment caches .It Ic l show and sort flows by when they were last active .It Ic ? toggle display of help/status text at the bottom of the display .El .Ss Packet classes .Pp All packet classes, or flows, are .Qq tagged with a descriptive string, such as .Ql "tcp ftpserver:20524 <-> cathexis:17771" . .Pp In addition to being tagged, some protocol-state information can be associated with a flow. This is displayed immediately below a flow line. Descriptive information for FTP, HTTP, X11 and SUP connections is determined from simple decoding of some packets. If the connection is 'open', it is introduced with a right angle shape (+), otherwise it is introduced with a hyphen character. .Pp .Bd -literal -offset indent tcp www:80 <-> hamartia:19179 + GET /index.html .Ed .\" .Ss Abbreviations .Pp Abbreviation patterns are a way of further combining flows. As packets are decoded, their flow name is constructed at the various protocol layers. At address combining stage (where arrows such as .Ql "->" are inserted) and at the final display stage, flow names are checked against a list of abbreviation patterns, and the abbreviation's name substituted if a match is found. For example, the pattern .Ql "* <-> *:domain" will match DNS packets in both the UDP and TCP layers. .Pp Abbreviations take the form .Op Ar abbrev Ns Li @ Ns .Ar pattern . The .Ar pattern part can contain the wildcard character, asterisk .Ql * which matches zero or more non-space characters. The space character matches one or more whitespace characters. Leading and trailing spaces are ignored. .Pp If the optional .Ar abbrev is not specified, the the pattern text itself is used as the abbreviation. .Pp Patterns are checked in the order given on the command line or in the files, i.e. as soon as one of the patterns matches a tag, no further patterns are considered. Recall that patterns can be applied multiple times to a tag. .Pp A patterns file can contain blank lines, which are ignored. Comment lines that commence with a .Ql # character are also ignored. .Pp After processing all command line abbreviations and abbreviation files, .Nm pktstat looks for and loads the files .Pa ".pktstatrc" , .Pa $HOME/.pktstatrc and .Pa @PATH_PKTSTATRC@ . This behaviour is suppressed by supplying an .Fl A Ic none option. .Sh EXAMPLES .Pp Here are the contents of my .Pa .pktstatrc file: .Pp .Bd -literal -offset indent dns @ udp *:domain <-> * dns @ udp * <-> *:domain irc @ udp 192.168.0.81:6666 <-> * .Ed .Sh SEE ALSO .Xr bpf 4 , .Xr tcpdump 8 .\" .Sh COMPATIBILITY .\" .Sh STANDARDS .Sh AUTHORS David Leonard, .Pa leonard@users.sourceforge.net .\" .Sh HISTORY .Sh BUGS .Pp DNS lookups can take too much time, possibly leading to missed packets. .Pp The data rates do not take into account data link framing overhead or compression savings at the data link layer. .Pp The direction of traffic is not taken into account: both ingress and egress data rates are combined. If you want to separate them, you will need to use a filter expression. .Pp Descriptive information for X11, FTP, HTTP and SUP flows is derived from the very first packets sent on those protocols. If you start .Nm after any of these flows have commenced, there may be no description available for them. .\" .Sh CAVEATS pktstat-1.8.5/xx_malloc.c0000644000175100017510000001117110763002545012277 00000000000000 /* * Simple wrappers around malloc/realloc/free so I can see * how much memory has been allocated by which functions */ #if HAVE_CONFIG_H # include "config.h" #endif #if DEBUG_MALLOC #include #include #include #include struct place; /* A header kept at the front of every allocation */ struct header { unsigned int magic; #define HEADER_MAGIC 0x3117deed #define FREED_MAGIC 0xdeed3117 struct header *next, **prevp; struct place *place; size_t size; }; /* A list head for each file:lineno onto which we chain every header */ struct place { struct place *next; const char *file; int lineno; struct header *head; unsigned int allocs, reallocs, frees; size_t size; }; /* List of known places */ static struct place *places; /* A flag to say that the atexit handler has been registered */ static int registered; /* Convert a malloc pointer to a header */ static void * ptr_from_hdr(struct header *h) { if (!h) return (void *)0; return (void *)(h + 1); } /* Convert a header to a malloc pointer */ static struct header * hdr_from_ptr(void *p) { if (!p) return (struct header *)0; return (struct header *)p - 1; } /* Returns at most the right-most len characters of s */ static const char * right(const char *s, int len) { int slen = strlen(s); return slen < len ? s : s + slen - len; } /* Dump a summary of allocations */ static void dump() { struct place *p; printf("%-25s %8s %8s %8s %8s\n", "Location", "#alloc", "#realloc", "#free", "unfreed"); for (p = places; p; p = p->next) printf("%20.20s:%-4d %8u %8u %8u %8u\n", right(p->file, 20), p->lineno, p->allocs, p->reallocs, p->frees, p->size); } static struct place * find_place(const char *file, int lineno) { struct place **p, *np; if (!registered) { registered = 1; atexit(dump); } for (p = &places; *p; p = &((*p)->next)) { int cmp = strcmp(file, (*p)->file); if (cmp < 0) continue; if (cmp > 0) break; if ((*p)->lineno == lineno) return *p; if ((*p)->lineno > lineno) break; } np = (struct place *)malloc(sizeof (struct place)); np->file = file; np->lineno = lineno; np->head = (struct header *)0; np->allocs = 0; np->reallocs = 0; np->frees = 0; np->size = 0; np->next = *p; *p = np; return np; } /* Remove a header from its place */ static void header_remove(struct header *h) { *h->prevp = h->next; if (h->next) h->next->prevp = h->prevp; } /* Insert a header into its place list */ static void header_insert(struct header *h, struct place *place) { h->next = place->head; h->prevp = &place->head; if (h->next) h->next->prevp = &h->next; h->place = place; } /* Checks the magic */ static void check_magic(struct header *h) { if (h) { assert(h->magic != FREED_MAGIC); assert(h->magic == HEADER_MAGIC); } } /* Wrap malloc() */ void * xx_malloc(size_t sz, const char *file, int lineno) { struct header *h; struct place *place; h = (struct header *)malloc(sizeof (struct header) + sz); if (h) { place = find_place(file, lineno); header_insert(h, place); h->magic = HEADER_MAGIC; h->size = sz; place->size += sz; place->allocs++; } return ptr_from_hdr(h); } /* Wrap realloc() */ void * xx_realloc(void *ptr, size_t sz, const char *file, int lineno) { struct header *h; struct place *place; check_magic(hdr_from_ptr(ptr)); h = (struct header *)realloc(hdr_from_ptr(ptr), sizeof (struct header) + sz); if (h) { if (h->next) h->next->prevp = &h->next; *h->prevp = h; h->place->size -= h->size; h->place->reallocs++; /* Move h onto a new place */ place = find_place(file, lineno); if (place != h->place) { header_remove(h); header_insert(h, place); } place->size += sz; h->size = sz; place->allocs++; } return ptr_from_hdr(h); } /* Wrap strdup() */ char * xx_strdup(const char *s, const char *file, int lineno) { size_t sz; char *s2; sz = strlen(s) + 1; s2 = xx_malloc(sz, file, lineno); memcpy(s2, s, sz); return s2; } /* Wrap free() */ void xx_free(void *ptr) { struct header *h = hdr_from_ptr(ptr); check_magic(h); if (h) { header_remove(h); h->place->size -= h->size; h->place->frees++; h->magic = FREED_MAGIC; memset(h + 1, 0xd0, h->size); } free(h); } #endif #if TEST_MAIN #include "compat.h" int main() { char *a,*b,*c[10]; int i; a = malloc(1024); b = malloc(2048); b = realloc(b, 4096); for (i = 0; i < 10; i++) c[i] = malloc(279); free(a); free(b); for (i = 0; i < 10; i++) free(c[i]); } #endif pktstat-1.8.5/abbrev.h0000644000175100017510000000041010762027257011557 00000000000000/* David Leonard, 2002.
