Description of problem:
On a system with more than one interface (EG: eth0, ppp0), traceroute will
pick the wrong source address. If this ends up being an unroutable address
(IE: Private-net interface on a firewall) then traceroute will not return
anything. Problem is fixed in 1.4a12 version of Traceroute.
Steps to Reproduce:
1. configure multi-interface machine (eth0 is private net, ppp0 is public
2. try to traceroute to external IP address
Actual Results: 1 * * *
2 * * *
There are many patches that you apply to the 1.4a5 version that you build
that may not apply to the current version. Someone will need to look at
each patch and see if the traceroute team has fixed them. Additionally,
you should send in any of the relevant patches to them to include (IE:
Patch to increase MAXHOSTNAMELEN, possibly using a define not already
included in the linux headers).
Has already been fixed in rawhide by updating to the newest traceroute source.
