POSIX threads configure test spins on Solaris
by Jonathan Abbey 17 Nov '03

17 Nov '03

Hi, folks. I've been negligent in trying out the newer iftop releases lately. I just tried to configure 0.15, and found that the POSIX thread test program spins indefinitely on Solaris, blocking the configure. I'm not very familiar with the POSIX Threads API so I don't know that I can debug this quickly. If I run a truss on the pthread test program, it exits out fairly quickly with a 0 exit value, but if I run it straight it just hangs. Any thoughts? -- ------------------------------------------------------------------------------- Jonathan Abbey jonabbey(a)arlut.utexas.edu Applied Research Laboratories The University of Texas at Austin GPG Key: 71767586 at keyserver pgp.mit.edu, http://www.ganymeta.org/workkey.gpg

iftop build fials: POSIX threads in NetBSD
by John Thompson 17 Nov '03

17 Nov '03

I'm trying to build iftop on my NetBSD-1.6.1 machine, but the config script dies with a complaint about POSIX threads: [...] checking pcap.h usability... yes checking pcap.h presence... yes checking for pcap.h... yes checkingfor a curses library containing mvchgat... -lncurses checking how to compile a working program with POSIX threads... no idea configure: error: can't figure out how to compile with POSIX threads If your system actually supports POSIX threads, this means we've messed up. Has anyone else tried building iftop for NetBSD or have any experience with POSIX threads in NetBSD? -- -John (JohnThompson(a)new.rr.com)

0.15pre4
by Paul Warren 07 Nov '03

The latest and greatest pre-release for the ever forthcoming 0.15 release is now available from: http://www.ex-parrot.com/~pdw/iftop/download/iftop-0.15pre4.tar.gz Only really bug-fixes and added documentation since the last pre-release. I do not intend to make any further changes before 0.15, so please let me know if it is broken. Paul

Iftop 0.14 on FreeBSD 5.1 using up all the file handles?
by iftop＠simhardware.co.nz 05 Nov '03

05 Nov '03

Hi Folks, For several weeks I have been running FreeBSD 5.1 Release (was on 4.7 previously). I am using the ports collection of iftop 0.14. What am am finding that that after a day or two I have thousands of open files on the OS. If I exit iftop, that number drops back down to 200 or so, and after I start iftop again it starts climbing again at a rate of about 3 or 4 files per second. I only noticed because after a week it is using all 7000 available file handles, and I get a kernel file table full errors, and everything stops. Anyone else seem this behaviour?

hi, Thanx alot for this super program... it is very helpfull for analyzing my network...:") I was wondering would it be harder a output to a file be implemented, more specificly it would be good if I can capture the total speed and/or total/MB transffered every X seconds. So that If I can say something like this : iftop --output-file /tmp/stat.log --interval 10sec -f 'net 192.168.0.0/24' I could get the info about the perfomance of the 192.168.0.0/24 network for the time iftop was runnnig and analyze it further.. time|Bytes|speed-kbit/s 0|1000|30 10|3000|37 .... and so on.. why I need this... I have two providers and switch between them based on the bandwith usage... this way I can gen rought estamites.. runing iftop in different configurations... One other idea was to be able to group the output of iftop based on some criteria say class C networks, I mean instead of seeing every host of the network, see their combined graph... So if I have 5 class C networks I can view their performance... and/or if many users access some outside class C network i can view total speed used to access these severs .. So it has to be source and/or dest based. or auto sensing when I exclude source "s" group on dest addresses, and vs. versa ("d"). Output based on class C networks would be very good too... this way with a single run I can make comparison of several source or destination nets... net|time|Bytes|speed-kbit/s 192.168.0.0/24|0|1000|30 10.10.0.0/24|0|1000|30 192.168.0.0/24|10|3000|37 10.10.0.0/24|10|3000|37 of course to protect of big dumps, I will have to use something like : -f 'net 10.0.0.0/24 or net 192.168.0.0/24' Third idea : make time periods for averaging the 3 speed columns configurable... that is for now... just my 5c.. iftop and tcpdump are most favorite diagnostic tools.. keep the good work
