    Question about traceroute


    Dear All,

    Am a new member to this forum I actually joined this group to know something about traceroute

    i know that traceroute helps you in route my machine and the server. My problem is when i tracecert from my windows local machine tracecert Yahoo! it gives me proper hops
    Tracing route to Yahoo! [87.248.113.14]
    over a maximum of 30 hops:

    1 <1 ms <1 ms <1 ms 000.00.00.00
    2 7 ms 3 ms 5 ms 00.000.00.000.static.vsnl.net.in [00.000.00.000]

    3 21 ms 4 ms 4 ms 00.000.00.000.static.vsnl.net.in [00.000.00.000]

    4 7 ms 4 ms 4 ms 00.000.00.000.static.vsnl.net.in [00.000.00.000
    0]
    5 148 ms 149 ms 149 ms 00.000.00.000.static.vsnl.net.in [00.000.00.000]

    6 284 ms 284 ms 285 ms if-0-1.core2.ldn-london.as6453.net [00.000.00.000]

    but from my linux server it give me the result as

    traceroute to Yahoo! (87.248.113.14), 30 hops max, 38 byte packets
    1 * * *
    2 * * *

    would like to knw why is this so.

    would be very greatful if someone could just explain me this

    tnx & regards

    this is a firewall issue, the server is behind a firewall that doesn't allow outgoing icmp packets

    tnk u for the reply dear,

    my servers are hosted at service providers which i access remotely thru putty.exe tool, you mean to say its their firewall access problem..
    i need to get in touch them.

    presumably your server is located behind a firewall, they have it configured to not allow ICMP outgoing packets (not uncommon, my work doesn't allow it)
