I'm very sorry for repost this. no manual entry for iftop-dump,and how does it to capture bandwidth information to a file? I put this command direct: test@test:~/test/iftop$ sudo ./iftop-dump [sudo] password for test: interface: eth0 IP address is: 172.25.25.212 MAC address is: 00:22:19:04:ce:49 netfilter option must be specified for iftop-dump Could not open log file: No such file or directorySegmentation fault so I create the log file folder "mkdir /var/bandwidth" and put command like this: sudo ./fitop-dump -F 192.168.0.1/32 now it's working, the log file bw-xxx have 4 column 。I think the 1 column is the time 2 column is the IP address ,but 3 and 4 column is 0. Although monitors IP in fact to have big traffic . so it cannot record the data which I want . where has made the mistake ？ -- Best Regards Sky Meng Network Engineer Lifewood Data Technology Limited Fax:+8676986718668 Mobile:+8676921378536 SkypeID:sky.lifewood.com Website: www.lifewood.com -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Display Problems on Solaris 10
by David Eisner 27 Jun '08

27 Jun '08

[ A tumbleweed blows by ...] Is this project being actively developed? It looks like the last update posted for download was in 2005. In any case, I downloaded iftop from Sunfreeware.com, and I'm having problems with a garbled display. Columns run together and I'll often see "0b0b0b" which I believe should be "0b 0b 0b" in separate columns. You can see what I'm talking about here: http://i158.photobucket.com/albums/t87/deisner/iftop_problem.png I downloaded the 0.17pre3 release and got it to compile, but it didn't help. By the way, here are two patches (to dlcommon.c and ui.c) needed to get iftop to compile on Solaris 10 with gcc 4.3.1. I'm including the compile errors, too, for Googlers: File: dlcommon.c Error: source='dlcommon.c' object='dlcommon.o' libtool=no \ depfile='.deps/dlcommon.Po' tmpdepfile='.deps/dlcommon.TPo' \ depmode=gcc3 /bin/bash ./config/depcomp \ gcc -DHAVE_CONFIG_H -I. -I. -I. -g -O2 -c `test -f 'dlcommon.c' || echo './'`dlcommon.c dlcommon.c:467: error: static declaration of 'sigalrm' follows non-static declaration dlcommon.h:35: error: previous declaration of 'sigalrm' was here Patch: ------------8<-------------- --- dlcommon.c.orig Fri Jun 27 11:48:53 2008 +++ dlcommon.c Fri Jun 27 11:49:03 2008 @@ -463,7 +463,7 @@ err("dlphysaddrack: short response ctl.len: %d", ctl.len); } -static void +void sigalrm() { (void) err("sigalrm: TIMEOUT"); ------------>8-------------- File: ui.c Error: (Problem here is that system /usr/include/curses.h gets picked up, rather than ncurses's) gcc -g -O2 -o iftop addr_hash.o edline.o hash.o iftop.o ns_hash.o options.o resolver.o screenfilter.o serv_hash.o sorted_list.o threadprof.o ui.o util.o addrs_ioctl.o addrs_dlpi.o dlcommon.o stringmap.o cfgfile.o vector.o -lpcap -lm -lsocket -lncurses ui.o: In function `ui_curses_init': /home/david/build/iftop-0.17pre3/ui.c:752: undefined reference to `initscr32' ui.o: In function `draw_bar_scale': /home/david/build/iftop-0.17pre3/ui.c:269: undefined reference to `acs32map' /home/david/build/iftop-0.17pre3/ui.c:269: undefined reference to `w32addch' /home/david/build/iftop-0.17pre3/ui.c:281: undefined reference to `acs32map' /home/david/build/iftop-0.17pre3/ui.c:281: undefined reference to `w32addch' Patch: ------------8<-------------- --- ui.c.orig Fri Jun 27 11:50:02 2008 +++ ui.c Fri Jun 27 11:50:13 2008 @@ -6,7 +6,7 @@ #include <sys/types.h> #include <ctype.h> -#include <curses.h> +#include <ncurses/curses.h> #include <errno.h> #include <string.h> #include <math.h> ------------>8-------------- -David -- David Eisner http://cradle.brokenglass.com

iftop 0.17 On HP-UX 11.23
by Franz, Jay 27 Aug '07

27 Aug '07

After much wailing and gnashing of teeth, I was able to successfully compile iftop 0.17 on HP-UX 11.23 by adding both LDFLAGS and CPPFLAGS definitions to the configure command and by patching two programs. The sordid details follow for any interested parties. Jay Franz jay.franz(a)ssa.gov ==================== First, my build environment: autoconf-2.61 automake-1.10 binutils-2.17 bison-2.3 flex-2.5.33 gawk-3.1.5 gcc-4.1.2 gettext-0.16.1 libiconv-1.11 libpcap-0.9.7 libtool-1.5.24 m4-1.4.9 make-3.81 ncurses-5.6 patch-2.5.4 perl-5.8.8 sed-4.1.5 shtool-2.0.7 termcap-1.3.1 texinfo-4.9 Secondly, my configure statement: # LDFLAGS='-lpthread -lipv6' CPPFLAGS='-I /usr/local/include/ncurses' ./configure And, finally, two patches, one for 'addrs_dlpi.c.patch' and one for 'dlcommon.c.patch'. addrs_dlpi.c.patch: 24d23 < #include <sys/sockio.h> 28a28 > #include <netinet/in.h> dlcommon.c.patch: 28a29 > #include <stdlib.h> 465c466 < static void --- > void -------------------- An explanation of the above. First, the build environment should be self-explanatory. the gcc, gettext, libiconv, and make packages were downloaded and installed from the Porting and Archiving Center for HP-UX (http://hpux.connect.org.uk/). All others were built on the target server. ---------- Secondly, the first LDFLAG, '-lpthread', addresses the failure of the configure script to accurately identify the threads capability in HP-UX 11.23. Running configure without the flag results in the following error: # ./configure <snip> checking POSIX threads compilation... CFLAGS= and LIBS= checking POSIX threads usability... configure: error: it fails. We probably guessed the wrong CFLAGS. I can provide the 'config.log' for anyone who wants it. ---------- The second LDFLAG, '-lipv6', addresses the error when linking all of the compiled programs: gcc -g -O2 -lpthread -o iftop addr_hash.o edline.o hash.o iftop.o ns_hash.o options.o resolver.o screenfilter.o serv_hash.o sorted_list.o threadprof.o ui.o util.o addrs_ioctl.o addrs_dlpi.o dlcommon.o stringmap.o cfgfile.o vector.o -lpcap -lm -lcurses ld: Unsatisfied symbol "if_nameindex" in file options.o ld: Unsatisfied symbol "if_freenameindex" in file options.o 2 errors. collect2: ld returned 1 exit status The 'if_nameindex' and 'if_freenameindex' symbols are defined in the 'ipv6' library. ---------- The CPPFLAG, '-I /usr/local/include/ncurses', addresses the following compilation error when compiling 'edline.c': source='edline.c' object='edline.o' libtool=no \ depfile='.deps/edline.Po' tmpdepfile='.deps/edline.TPo' \ depmode=gcc3 /bin/sh ./config/depcomp \ gcc -DHAVE_CONFIG_H -I. -I. -I. -g -O2 -c `test -f 'edline.c' || echo './'`edline.c edline.c: In function 'edline': edline.c:68: error: 'KEY_END' undeclared (first use in this function) edline.c:68: error: (Each undeclared identifier is reported only once edline.c:68: error: for each function it appears in.) make[2]: *** [edline.o] Error 1 make[2]: Leaving directory `/usr/local/install/iftop-0.17' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/local/install/iftop-0.17' make: *** [all] Error 2 It is possible that this could be addressed in the configure script, since it appears to correctly identify the native 'curses' library; however, 'gcc' fails to locate the native library and forcing its inclusion (i.e., -I /usr/include) has no effect. ---------- Thirdly, the first patch, for 'addrs_dlpi.c' addresses the following compilation errors: source='addrs_dlpi.c' object='addrs_dlpi.o' libtool=no \ depfile='.deps/addrs_dlpi.Po' tmpdepfile='.deps/addrs_dlpi.TPo' \ depmode=gcc3 /bin/sh ./config/depcomp \ gcc -DHAVE_CONFIG_H -I. -I. -I. -I /usr/local/include/ncurses -g -O2 -c `test -f 'addrs_dlpi.c' || echo './'`addrs_dlpi.c addrs_dlpi.c:24:24: error: sys/sockio.h: No such file or directory addrs_dlpi.c:53: warning: 'struct in_addr' declared inside parameter list addrs_dlpi.c:53: warning: its scope is only this definition or declaration, which is probably not what you want addrs_dlpi.c: In function 'get_addrs_dlpi': addrs_dlpi.c:184: error: dereferencing pointer to incomplete type addrs_dlpi.c:190: error: dereferencing pointer to incomplete type addrs_dlpi.c:190: error: invalid application of 'sizeof' to incomplete type 'struct in_addr' make[2]: *** [addrs_dlpi.o] Error 1 make[2]: Leaving directory `/usr/local/install/iftop-0.17' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/local/install/iftop-0.17' make: *** [all] Error 2 The first error, regarding the 'sys/sockio.h' header file, is resolved by removing the include statement, as this file does not exist on HP-UX 11.23. The other errors, regarding the 'in_addr' structure, are resolved by including the 'netinet/in.h' library, where it is defined for HP-UX 11.23. ---------- The second patch, for 'dlcommon.c', resolves the following compilation errors and warnings: source='dlcommon.c' object='dlcommon.o' libtool=no \ depfile='.deps/dlcommon.Po' tmpdepfile='.deps/dlcommon.TPo' \ depmode=gcc3 /bin/sh ./config/depcomp \ gcc -DHAVE_CONFIG_H -I. -I. -I. -I /usr/local/include/ncurses -g -O2 -c `test -f 'dlcommon.c' || echo './'`dlcommon.c dlcommon.c:467: error: static declaration of 'sigalrm' follows non-static declaration dlcommon.h:35: error: previous declaration of 'sigalrm' was here dlcommon.c: In function 'expecting': dlcommon.c:531: warning: incompatible implicit declaration of built-in function 'exit' dlcommon.c: In function 'err': dlcommon.c:1333: warning: incompatible implicit declaration of built-in function 'exit' dlcommon.c: In function 'syserr': dlcommon.c:1340: warning: incompatible implicit declaration of built-in function 'exit' make[2]: *** [dlcommon.o] Error 1 make[2]: Leaving directory `/usr/local/install/iftop-0.17' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/local/install/iftop-0.17' make: *** [all] Error 2 The errors, regarding re-declaration of the 'sigalrm' function, are resolved by removing the 'static' statement from the re-declaration of the function. This does allow the 'dlcommon.c' program to compile cleanly and the resulting build of iftop appears to work as expected; however, I am not a C programmer and this may not have been what was originally intended. YMMV. The warnings, regarding the 'exit' function, are resolved by including the 'stdlib.h' header file. ====================

iftop 0.17 On HP-UX 11.23
by Franz, Jay 22 Aug '07

22 Aug '07

I am attempting to compile iftop 0.17 on an HP Integrity (i.e., IA64) server under HP-UX 11.23. I am using the following GNU build environment: ar : GNU ar 2.17 as : GNU assembler 2.17 autoconf : autoconf (GNU Autoconf) 2.61 automake : automake (GNU automake) 1.10 bison : bison (GNU Bison) 2.3 flex : flex 2.5.33 gawk : GNU Awk 3.1.5 gcc : gcc (GCC) 4.1.2 make : GNU Make 3.81 nm : GNU nm 2.17 sed : GNU sed version 4.1.5 shtool : GNU shtool 2.0.7 (19-May-2007) And, the following configure command: CFLAGS='-lpthread' CPPFLAGS='-I /usr/local/include/ncurses' CC=gcc ./configure The CFLAGS parameter is required to overcome an error in configure, to correctly identify the threads capability in HP-UX. The CPPFLAGS parameter is required to overcome an error in make, to correctly located the ncurses library. The command results in the following make error: source='addrs_dlpi.c' object='addrs_dlpi.o' libtool=no \ depfile='.deps/addrs_dlpi.Po' tmpdepfile='.deps/addrs_dlpi.TPo' \ depmode=gcc3 /bin/sh ./config/depcomp \ gcc -DHAVE_CONFIG_H -I. -I. -I. -I /usr/local/include/ncurses -lpthread -c `test -f 'addrs_dlpi.c' || echo './'`a ddrs_dlpi.c addrs_dlpi.c:24:24: error: sys/sockio.h: No such file or directory addrs_dlpi.c:53: warning: 'struct in_addr' declared inside parameter list addrs_dlpi.c:53: warning: its scope is only this definition or declaration, which is probably not what you want addrs_dlpi.c: In function 'get_addrs_dlpi': addrs_dlpi.c:184: error: dereferencing pointer to incomplete type addrs_dlpi.c:190: error: dereferencing pointer to incomplete type addrs_dlpi.c:190: error: invalid application of 'sizeof' to incomplete type 'struct in_addr' make[2]: *** [addrs_dlpi.o] Error 1 make[2]: Leaving directory `/usr/local/install/iftop-0.17' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/local/install/iftop-0.17' make: *** [all] Error 2 # The first error, regarding the 'sys/sockio.h' header can be overcome by removing the include from the addrs_dlpi.c source, since, according to HP, the socket ioctl definitions are defined in the /usr/include/sys/ioctl.h' header file, which is included in the addrs_dlpi.c source. However, removing the 'sys/sockio.h' reference only resolves the first error; the other errors, regarding the pointer dereferencing and the type application remain. The section of addrs_dlpi.c code apparently generating the errors looks like: 178 #ifdef SIOCGIFADDR 179 180 fd = socket(PF_INET, SOCK_DGRAM, 0); /* any sort of IP socket will do */ 181 182 strncpy(ifr.ifr_name, interface, IFNAMSIZ); 183 184 (*(struct sockaddr_in *) &ifr.ifr_addr).sin_family = AF_INET; 185 186 if (ioctl(fd, SIOCGIFADDR, &ifr) < 0) { 187 fprintf(stderr, "Error getting IP address for interface: %s\n", "ge0"); 188 perror("ioctl(SIOCGIFADDR)"); 189 } else { 190 memcpy(if_ip_addr, &((*(struct sockaddr_in *) &ifr.ifr_addr).sin_addr), sizeof(struct in_addr)); 191 got_ip_addr = 2; 192 } 193 #else 194 fprintf(stderr, "Cannot obtain IP address on this platform\n"); 195 #endif Although the warnings appear to reference the structure definition generating the errors: 51 52 int 53 get_addrs_dlpi(char *interface, char if_hw_addr[], struct in_addr *if_ip_addr) 54 { 55 int got_hw_addr = 0; 56 int got_ip_addr = 0; 57 Any ideas as to where to go next? Any help would be appreciated. Thanks. Jay Franz jay.franz(a)ssa.gov
