When I try traceroute it only gives me stars as output. For example:
Code:
me@desk:/etc/udev/rules.d$ traceroute taobao.com
traceroute to taobao.com (121.14.24.241), 30 hops max, 60 byte packets[code]....
It gives me some output when tracerouting to other computers within my network:
If I traceroute to google, it hits my router and stops there. Generically, my Setup is this. AT&T Uverse residential gateway ---> wired to 54g router running tomato ---> wireless ethernet bridge to 54gl router running tomato in another room ---> wired to ubuntu and win7 box.
The ATT RG hands its external IP over the the 54g running tomato. the 54gl running tomato is a wireless ethernet bride in the den running the same with 2 machines wired to. The two machines are static IP to the first router, which does all DCHP, stuff like that. The Windows box is fine. The subnets are the same. What should I be looking at to figure this out? This is the only "network" issue I have come across.

As i've installed the new fedora update packets ,i've seemed to develope a strange networking problem .. Network description Fedora 15 with 3 LAN adaptors eth0 > LAN (IP address 192.168.0.254)eth1 > network connected to a pppoe conection eth2 > WAN to another provider. Ok so let's ignore eth2 because i've disable mangle(i was using trafic shifting on some ports). So now i'm using it as a simple NAT server .. so the problem is : >>my server is not responding to the traceroute command is it should .. the network works thou but this is what i get.

I've used linuxquestions.org from time to time, but never needed to register until now.An in-depth explanation of this issue is already described over here: [URL], so I will merely quote it again here - it seems nobody knows the solution over at Ubuntu's forums...:
Quote: I recently switched my home server from debian lenny to ubuntu maverick. I've managed to port all my configs and stuff and so far I'm very happy. There's one tiny thing that's griping me, that I never experienced before with debian's (older) packages/configuration... Here's the situation: My server dials up 2 pppoe (adsl) interfaces (different isp's) with split internet routes.
If I run a general traceroute to an internet IP, all the hops which are not routed via the same interface as the destination host/IP, will appear as "* * *" in the traceroute. This was never the case before and it would be preferred to see the IP's of all routers along the way regardless of whether they are routed... (I used to be able to see IP's like 10.0.0.x before through INTERNET traceroutes if they were hops along the way [IP's which would be unreachable if traced directly], and that's no longer the case) - isn't this kinda defeating the point of traceroute?

Can't figure out why 10.10 won't load. I loaded FEDORA no problem, loaded 11.04 no problem. 10.10 stops with the stars litup and will go no further. can't find anything wrong with the hard drive.

View 7 Replies View Relatedwhat the difference between the commands tracert and traceroute is? I need to run tracert as superuser, while traceroute is no problem in user mode.
Also, it appers like tracert is showing nodes completely different from traceroute:
Code:
sudo tracert google.nl
traceroute to google.nl (216.239.59.104), 30 hops max, 60 byte packets
1 192.168.1.254 (192.168.1.254) 1.078 ms 1.699 ms *
2 * * *
[Code]....
Another thing.. Is it correct to assume that hop 5 and 7 above are loadbalanced nodes? How should I interpret this result, is the traceroute initiating it's path three times? Otherwise it'd be rather strange as to display other addresses in the same node..
naman@naman-laptop:~$ traceroute google.co.in
google.co.in: Name or service not known
Cannot handle "host" cmdline arg `google.co.in' on position 1 (argc 1)
Then I tracked the IP address of google.com on [URL] and tried
naman@naman-laptop:~$ traceroute 74.125.77.99
traceroute to 74.125.77.99 (74.125.77.99), 30 hops max, 40 byte packets

I have to use my college proxy server to connect to the Internet. When I traceroute to a host within the LAN there is no problem. What should I do to be able to traceroute to a host outside my local network?
As root I get the following result: ngssuse:~ # traceroute -nI 10.200.123.45
Note: the -i and -I options were exchangedfor compability with LBL traceroute Use -I for ICMP, and -i <ifname> to specify the interface name unable to create ICMP send socket: Permission denied. Is this a bug?
Is there some traceroute-like tool that shows ports as well as IP addresses? This is more for seeing how NAT works (on my home network) than for a practical need.

What am I doing wrong? Should I be disabling DNS caching? Is there a property I haven't set correctly? Just a small FYI, but I dual boot this computer with Win7 and it's tracert works fine. UPDATE: I also ran the command from a different network and it worked fine. I'm assuming I need a port forward then?
I want to give access to a student to a server in order to make repeated trials of traceroute to different hosts. We have realized that it is preferable to use the -T option, as it sends TCP packets that are less commonly blocked by firewalls. However, this option is only available to superusers, and I don't want to grant the student such privileges.
View 2 Replies View RelatedI ran two scans in Zenmap: 1) Quick scan plus and 2) Quick Traceroute. Quick scan plus, under the Nmap Output tab, has a field called "Network Distance". The Quick Traceroute report under the same tab lists the HOP and RTT time. I was thinking that for a given server, the value for the Network Distance would be the same as the HOP field when initiating the scans from the same server, but they are not.

And yes, it works without the "-I". But it should work with the "-I". One shouldn't have to boot into Windows, just to run "tracert" there.

View 6 Replies View RelatedI'm trying to implement a routing short-cut solution, whose requirement is as following: server1(Linux) sends ip packets(destined to server3) to server2(Linux) via an ip tunnel between them, server2 forwards the ip tunnel's output (the inner ip packets) to server3. Each server has only one NIC and a public ip associated with it. All servers can communicate with each other. I'm sure the ip tunnel between server1 and server2 was configured correctly and worked well. server2's ip_forward was enabled too. On server2, I can capture the traffic on the ip tunnel interface, and they are originated from server1 and destined to server3. The problem is server2 does not forward the ip tunnel's output at all. On server2, I just run "echo 1 > /proc/sys/net/ipv4/ip_forward". Is there anything I missed for enabling ip_forward? Or originally, ip forward can't work on servers with only one NIC, can it?

I have a proxy tunnel server which the client connects trough SOCKS protocol, for ex: he opens a ssh window "ssh -D 1070 server.com" and set his connection to SOCKS v5 on 127.0.0.1:1070.I want that, when someone uses the proxy, the external ip the persons gets to be random, not always externalip1! Or... if he uses externalip2 to connect on ssh, his externalip should be externalip2. I don't want every user with the same external IP.
