[BusyBox] traceroute -I?

[Craig Skinner]

Hi list,

I admit that I'm not a C programmer, so this is a feature request to
those with the skills & time (eek!):

It would simplify firewall rules where multiple layers of firewalls from
differnet vendors (Cisco, single box ADSL router/firewalls) are used if
traceroute used portless ICMP packets instead of slow UDP. (Yes I know
that UDP is faster than TCP).

For example on my OpenBSD dual homed bastion servers, I could allow ICMP
traceroutes from the external load balancing firewall (busybox) to the
internal network/firewall. This would ease network testing, esp in cron
driven scripts.

Windoze uses ICMP in its tracert (about the only clever bit of thinking
on their part), and full Linux/BSD traceroute has the -I flag to do
likewise, which I always set in /etc/profile as an alias.

Thoughts?

Craig.
