Hi everyone, I'm trying to understand if the DNS problem I'm having is my fault or my ISP's fault.
>From the server, I try to get to three different locations: [EMAIL PROTECTED]:~$ traceroute 207.218.245.47 traceroute to 207.218.245.47 (207.218.245.47), 30 hops max, 38 byte packets 1 ivhou-207-218-245-47.ev1.net (207.218.245.47) 0.554 ms 0.431 ms 0.192 ms # this one is trying to go to my client's IP # Note the !H -- host unreachable # I *can* connect from other machines that are not my server though.

My ISP is trying to tell me that I have a firewall installed on the server. I've done a plain debian install which does NOT include a firewall. My ISP is refusing to help because I have debian installed. I'm pretty sure it's not actually my fault though.... Any thoughts would be much appreciated!! emma -- Emma Jane Hogbin [[ 416 417 2868 ][ www.xtrinsic.com ]] ----- End forwarded message ----- -- Emma Jane Hogbin [[ 416 417 2868 ][ www.xtrinsic.com ]] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
