| Post subject: traceroute from China to Europe |
Hi All,
I was told to test my connection to a server in Europe using the DOS command tracert addressofserver which supposedly shows there the data goes through and how long it takes. Basically I can browse to that server but it is very slow.
My problem is the tracert test fails... (Request time out all the time). So I did a test on yahoo.com...
C:\>tracert www.yahoo.com
Tracing route to www.yahoo-ht3.akadns.net [87.248.113.14]

My understand (I dont understand much about IT) is that this is an appalingly bad result.
Is it normal?
In case I need a reliable and fast connection to a specific server in Europe, from my office, how should we proceed? It seems China Telecom is useless. But if they can't do it, who can?
Thanks! |

No, it just shows you that your routers is not letting pings (ICMP packets) through.
You can probably turn this on / off at the router.
819ms - is not outrageous for yahoo.
I'm getting 235 for yahoo / 381 for the mirror you were using at 11:52pm at night, so it sounds reasonable if its a ping from daytime.

First off, you don't even have a router on your system ? What are you using as a gateway, China Telecom direct ? are you on dsl or fttb or what ?
Second, "timed out" doesn't necessarily mean that the connection timed out. A lot of people these days think it's really clever to set their routers to not return icmp requests. Stupid stupid stupid but they think it's oh so clever to not let people know ... what ? Where a router is ? Sheesh.
22 hops seems like a lot tho - you're in shanghai while I'm ten thousand kilometers from a flush toilet. Yet I get there in 13 hops ...
I've heard that China Unicom is offering a 2Mbps fiber connection for 800 rmb / month. Really want to check that out as soon as I have a moment. |

To confirm, I also get about 12 routers in before I hit yahoo also.
Traceroute to the f1.xxx is 14 hops
Its possible he's using a VPN -> Europe and then out from there, and I'd probably surmise CISCO router, most sysadmins default those to default security level anal. |

That's such a pain in the arse if you ever want to figure anything out and it doesn't accomplish anything of value, sheesh  Seems strange to get no returns from anywhere tho ...  |

Thanks a lot, guys.
I am home now, thats where I did the last test. Crappy connection, supposedly 1 Mbps... we are going to drop them. Not sure about router - we have a wireless hub and that box that connects into the wall...
When I tried in office earlier today, everything timed out when trying to connect to that corporate server we need to use.
In practice what do we do?
We go to China Telecom and ask their help? You check with their competitors? |

So if I understand well, it means the signal goes though 22 routers to reach yahoo, but none of them allows "ping" or only the last one does.
Still it takes me 10 more hops that you guys! |

I'd
1) pay CS to come on over and see what he can figure out
2) check out China Unicom and see if their fiber deal is good. Your very own fiber connection is pretty nice and China Telecom charges businesses a ridiculous amount for dsl. |

I think my home connection goes through the water pipes or something like that, the technician did something wrong when he installed. Thats why my PC is leaking water. |

I have just informed a special talk force in the FBI about your IP address 220.112.110.50 , they should arrive at your flat shortly to give a hand |

You are using Great Wall

What do you expect, you use a 3rd tier provider. Get DSL or FTTB, Cable is crap.
China Telecom (Shanghai Telecom is a subsiduary) owns the network.
Anyone else buys from them, so any network goes through providers network back to .... Shanghai/China Telecom. May as well use Shanghai Telecom.
Basically you are bouncing around the Cable network until you reach their connection to Shanghai Telecom, and then out.
Cable is horribly congested network wise, plus they rate limit downloads and torrents. No point using them at all.
Comparison.
From my server (local in Shanghai Telecom's main data centre) to your ip address:

(dies after that - 10.xxx is internal network, so its bouncing around whatever hacked up routing they do internally).
142ms, is pretty crappy for inside china - inside china.
Compare to a traceroute to my house ip address:
pop:/home/www/webmail/web2# traceroute 58.41.127.28
traceroute to 58.41.127.28 (58.41.127.2, 30 hops max, 40 byte packets

5 222.72.255.130 (222.72.255.130) 1.144 ms 1.288 ms 1.116 ms
6 daole;)
A lot less hops, and a damn sight faster.
Or from the reverse end:

Doesn't really help you though.
Whats the ip of the server in Europe?
Is it in UK? There are a few hosting companies in UK that are blocked from here.
Its possible that the provider your company is on at the remote end is blocked, hence you can't connect. |

Thanks. First thing is to get rid of the cable connection. We had decided to do that anyway. Their service is crap.
Will look into the rest tomorrow.
I should probably contact you for my and some of my customers network issues. Will try to do so.
Thanks a bunch |

Was told by the company's IT types that it really didn't matter which provider you used. There's a general problem with connections to Europe. Apparently, the "pipe" allocated for Europe is much smaller than that for the US.
Company had 3 IP addresses (one for each provider).
When one of our customers had a big transfer to do, we used to ping Europe using all 3 to see which was fastest du jour and then tell our customer which one to use that day.
Was actually faster for those customers that had US entities to go through their US servers.
Don't really understand all this, but that's what we had to do. |

FYI this is what I get connecting to yahoo in my office (China Telecom connection). Based on all the comments above, I think this is pathetic, so now I am going to cry.
