Re: [Planetlab-users] plkmodutil traceroute

[Krishna G. <gu...@cs...>]

Here's a simple trick to fix this.

Looking over the source code at:
http://cvs.sourceforge.net/viewcvs.py/planetlab/plkmodutil/

It appears that the PlanetLab traceroute program tries to bind to a
default port (33433) for all users. So there is no way two traceroute
programs can be simultaneously run by the same or even different users !

I added a few lines to "traceroute.c" file to retry random ports when the
bind fails and so far it works fine for me. The modified source code
(binary) are at:

www.cs.washington.edu/homes/gummadi/temp/my_pl_traceroute-1.4a12
