For some reason i cannot do a traceroute from my mac. I haven't remeberd to test it from other networks. The reason i think it is my Mac and not just my network is becuase all the other PC's in the house work. I am the only mac by which to test it.



I have tried witht he 10.3.4 network utility, the terminal with traceroute command and a 3rd party thing. it just takes forever and shows absolutly nothing but ****



Any ideas? I would really like to be able to work with the traceroute. I help-out at my host's fourms (Lunarpages) and it is helful to see if/where there may be a slowdown along the route.



Thanks

    Have you enabled a firewall? Do other net related things work?

    No firewall except my router. (sharing says "firewall off." I don;t thing the router is doing anything becuase the PCs work on the same stuff.



    Pings and other stuff work fine.

    If ping works but not traceroute, then I'm baffled. You can try it from single user more (reboot and hold down command S) and if it works, then it's something in Mac OS X. If it still fails, it could be just about anything, on your Mac or off. The other thing to try is plugging your Mac directly into your broadband (to rule out the router) and into someone else's network.



    Sorry I can't be of more help.

    Windows tracert uses ICMP only. Unix uses ICMP and UDP.

    If the traceroute works from a pc on the same subnet then enable udp any for the mac(unix) box.

    My initial thoughts are that traceroute has been on a router somewhere.

    If you enter traceroute own_ip_address and it works then traceroute works and you problem lies with network config either on the mac or a return imcp somewhere.

    How do you enable UDP? Is there a setting in Mac OS that i can change?

    If you do this, and post the results, we have a much better chance of helping you. I seriously doubt your router is dropping UDP packets, that's a pretty lacking default state for something that is designed to pass packets.

    I do not know if you want me to trace my IP as in on the router, subnet or the internet. Here is both

    Can you confirm that a PC in the subnet 192.168.1.x can successfully tradceroute to 68.84.232.99.



    So your mac is in the subnet 192.168.1.0/24 presumeably.

    What do you mean when you say that 192.168.1.100 is subnet. Do you mean the broadcast mask or the ip of the mac?

    I just reread my post. I said subnet but i meant my own computer's IP address from the router.

    Your traceroute is successfully seeing the router.

    Do you PC's use the same router?

    Is there a firewall anywhere?



    Dobby.



    P.S. You can also traceroute from some of the better routers. Does yours support this?
