I use iftop (I love it) version 0.16. I seem to have some problem getting name resolution to work. I seems to some of the time and then it doesn't. Could someone fill me in on what I should know that I don't?

iftop-0.16 on NetBSD
by John Thompson 29 Jun '04

29 Jun '04

Several weeks ago I posted about a problem configuring iftop to compile on NetBSD-1.6.1; specifically, the configure script would die when it came to checking for Posix thread support. I've now updated that machine to NetBSD-1.6.2 and the configure script runs to completion without complaint (after passing it LDFLAGS=-L/usr/pkg/lib/ and CPPFLAGS=-I/usr/pkg/include to point it to the Posix thread support). Unfortunately, it fails during the compile: gcc -g -O2 -L/usr/pkg/lib/ -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 -lncurses -lpthread ui.o: In function `draw_bar_scale': /tmp/iftop-0.16/ui.c:269: undefined reference to `_acs_char' /tmp/iftop-0.16/ui.c:281: undefined reference to `_acs_char' ui.o: In function `ui_loop': /tmp/iftop-0.16/ui.c:1055: undefined reference to `__error' /tmp/iftop-0.16/ui.c:1057: undefined reference to `__error' Any ideas where to go from here? -- -John (john(a)os2.dhs.org)

Building on Solaris redux
by Jonathan Abbey 24 Jun '04

24 Jun '04

Hi everyone, hope things are going well for y'all. I just got around to building iftop 0.16 on our Solaris systems, and ran into the integers.h problem in options.c.. I see this was correctly reported a few months ago, but I'd assume this would give at least minor grief to anyone who was trying to build on Solaris without checking the mailing list archives. I believe a patch was already reported on this, but if not, here's a handy one that could be applied.. hint, hint. ;-) Thanks!

small but anoying bug in iftop-0.16
by richard lucassen 29 May '04

29 May '04

Seen on a RedHat-7.3 and a Debian-Woody system: When running iftop-0.16, you can press "o" (letter o) to freeze the order. From that moment, the "total" column is counting much more than it should. Also the displayed bandwidth in the other columns is incorrect. I hope you can reproduce it, if not I can give you access to one of the machines.

iftop 0.16 on HP-UX
by John Caywood 05 May '04

05 May '04

Had to make these changes to compile under HP-UX 11.00 1. in edline.c KEY_END is undefined anywhere comment out this case 2. in options.c u_int32_t is uint32_t in HP-UX (sys/types.h) struct if_nameindex is struct ifnet in HP-UX (net/if.h) 3. in resolver.c wait() requires an argument of type int * changed wait() to wait( (int *) (pid_t) -1) 4. in ui.c before #include <curses.h> add #define _XOPEN_SOURCE_EXTENDED 5. in addrs_dlpi.c add #include <netdb.h> Got through the compile phase with these changes, but at load time, 'ld' choked when trying to find if_freenameindex() and if_nameindex() Can anyone suggest where I might find these functions? Or is the port hopeless because different data structures are being used for kernel if structures? ===== John Caywood biliary two thousand at yahoo dot calm __________________________________ Do you Yahoo!?

measuring bandwith ?
by raptor 03 May '04

03 May '04

hi, I'm tring to use libpcap to measure bandwith.. the reason I need this is to launch this small program that will measure the bandwith usage (tcpdump filter based).. it will not be ncurses based,, My problem is how to set this program to capture the traffic for 10 seconds for example ... and most importanly how u calculate that 1 second is passed, so that u calc "kbps"... Could u explain...(i'm not a C programmer but have idea what is all about) Second question I've used pcap sniffer.c example from tcpdump.org, and modified so that i calculate the packet sizes in two different ways i.e : total_len2 += ntohs(ip->ip_len); total_len += header->len; into got_packet() callback function... I see that iftop uses the first one, is it more correct... tia.. PS. One second question is what if I put several filters in text files and loop over them i.e. read the first filter, setfilter(), mesure for 10 sec, then read the second filter...etc.etc.. will there be some calculation error 'cause I'm switching filters i.e. will I have to wait some time before start measuting say : 1. setfilter() 2. wait 1 sec 3. measure 10 sec 4. goto 1

Hello everyone, I am having trouble with the make command installing iftop on Solaris 9. I have installed libpcap, and ncurses. The configure command ran fine, and I also installed in promisicus mode. Below is the error I am getting when I run the make command. ld: fatal: Symbol referencing errors. No output written to iftop collect2: ld returned 1 exit status *** Error code 1 make: Fatal error: Command failed for target `iftop' Current working directory /opt/iftop/iftop-0.16 *** Error code 1 make: Fatal error: Command failed for target `all-recursive' Current working directory /opt/iftop/iftop-0.16 *** Error code 1 make: Fatal error: Command failed for target `all' Any assistance would be greatly appreciated.
