tcptraceroute does not work on a Leopard Intel Macbook with Ports version 1.6

[simon@…]

I'm having the same problem as in Ticket #7972 which has been closed. With a fresh install of ports on a MacTel machine and having just installed tcptraceroute:

$ uname -r
9.5.0

$ port --version
MacPorts 1.600

$ port installed
The following ports are currently installed:
  libnet11 @1.1.2.1_1 (active)
  tcptraceroute @1.5beta7_0 (active)

$ sudo tcptraceroute bbc.co.uk 80 199
Selected device en1, address 192.168.1.64, port 49990 for outgoing packets
Tracing the path to bbc.co.uk (212.58.224.138) on TCP port 80 (http), 30 hops max, 199 byte packets
libnet_write failed?  Attempted to write 199 bytes, only wrote -1

Is this a driver issue? Is this a libnet issue? PEBKAC?

FWIW, that command succeeds for me on a machine that matches your described configuration.

Hard to tell what's going on, it works for me as well on a MBP, 10.5.5, Xcode 3.1.1, both with MacPorts from trunk and 1.6. The trunk MacPorts linked against the libpcap port, but the 1.6 MacPorts linked against the system libpcap; other than that, it just links against standard libraries.

I take it en1 is the right interface for it to be using?

After just having a dig around I found that the problem was PEBKAC, I had tried to compile it from source and I had a rogue binary in my path :S

Sorry about that, works fine now.

$ which tcptraceroute

Ah, good to hear it's working now.
