AccurateRip Moved to a new Home

Re: AccurateRip Moved to a new Home

Also try opening an FTP connection to 74.86.240.219, do you get the FTP login message?

The ISP I use at home doesn't use a proxy (as all ISPs in Italy). My corporate network, which is the one it works, does have a proxy.

From corporate net:
> ftp 74.86.240.219
Connected to 74.86.240.219.
Connection closed by remote host.

I'll to FTP from home late today.

Re: AccurateRip Moved to a new Home

Hello

I live in Luxemburg (EU) and i am lucky not to have any problem with accuraterip.
But having troubleshooted network issues in the past i suspect there is a problem with "arp" requests.
This mainly happens in cluster configurations where virtual ip and mac addresses are used resulting in incomplete or corrupted arp tables.

So somewhere in the network path, the arp table might be stuck or corrupt and is leading to a wrong ip address. I don't want to make a diagnostic leading into wrong direction, but i would also suspect the server side.

A quick test would be to make a static arp entry on the client workstation with the physical mac address and physical ip, but i doubt that Spoon would reveal the real MAC to the public.

I also suspect 74.86.240.219 is virtual or hsrp. Normally if you ping or try to ftp from the client workstation to the active server physical address this could solve the problem.

@ Spoon. An easy test would be to ping the outside ip address of the client router, as this would update his arp table and eventually solve the problem.

Kind regards

Re: AccurateRip Moved to a new Home

74.86.240.219 should not be virtual, it is only used on that sever (we have another 10 ip addresses for that server).

----
If the FTP test is working you should see something like:

Status: Connecting to 74.86.240.219:21...
Status: Connection established, waiting for welcome message...
Response: 220 Microsoft FTP Service
Command: USER test
Response: 331 Password required for test.
Command: PASS ****
Response: 530 User test cannot log in.
Error: Could not connect to server

-------
Right the other server is 74.86.240.218, try pinging that one (it will respond to pings), try also tracert 74.86.240.218

I am thinking it is the hardware firewall, (218 is not protected by the firewall yet).

Re: AccurateRip Moved to a new Home

Ok for 74.86.240.219 I have enabled ICMP (ping and tracert), try pinging the server, try the www.accuraterip.com now.

But http requests time out still :( So something is defenitly off since dbpoweramp.com works fine.

Also neither 74.86.240.218 nor 74.86.240.219 responds to ftp requests on port 21.

Re: AccurateRip Moved to a new Home

dbpoweramp.com is a different datacenter.

We know it is not the server software: .219 is Windows Server 2003 an .218 is RHEL
It is not the firewall as .218 is not using it yet.

@Ney

I am wondering why your first hop has request timeout.
This should normally be your default gateway, either from DSL router or from ISP when using dial-up.

Try to ping with max MTU size and check for timeouts.
"ping -f -l 1464 www.accuraterip.com -t"
this will send packets with the max possible unfragmented MTU size.

if this is working i suspect a firewall issue at your site doing content checks on http frames and blocking ftp.

Try also "telnet www.accuraterip.com 80" and check if you have connection.

Also would be interesting to see the routing table of your workstation. "route print"


kind regards

Re: AccurateRip Moved to a new Home

My default gateway does not respond to ping from the LAN side, its either a bug or a feature, its annoying but not something that is worth to try and fix.

Today I can reach www.accuraterip.com but when i try to access the list of keydiscs it loads very very slowly. after 2½ minutes i have got 60kb, and 3½ i now got 63kb. This seems very odd, since this forums loads fine.

Edit: Its very odd looking at the ftp and telnet responses differs between linux and windows. It really seems that some kind of filter operates on accuraterip.com

Edit2: forgot to say that pinging with maximum framesize etc works just fine.

Edit3: And I run Vista Buisness 32-bit with Sp1 RC.

Re: AccurateRip Moved to a new Home

Has someone of you tried to reboot the DSL router ?
@Kupje,@NEY
I suspect you have a firewall issue on your Xp or DSL router.
Try to stop the windows firewall on your Winxp machine.
"net stop sharedaccess"

Try to ftp or browse to www.accuraterip and while doing this open a second cmd box and run "netstat -n 1" and check for the state of the connections.

also run "netstat -s" and check for errors when browsing or pinging.

[Ney]

Re: AccurateRip Moved to a new Home

No firewalls are running here. The DSL router havnt been reset recently no, but I can't see why it should pose a problem (it only has NAT no active firewall). I have no experience using netstat, so I wouldnt know what to look for when browsing accuraterip.com

Btw in 40 minutes http://www.accuraterip.com/driveoffsets.htm finished loading 10%, then my browser gave up.

edit: I get ESTABLISHED on port 80 using TCP when browsing www.accuraterip.com

Oh and ftp requests to 74.86.240.219 responds now. although its very slow

netstat says ESTABLISHED on the connection on port 21.

[Spoon]

Re: AccurateRip Moved to a new Home

>Oh and ftp requests to 74.86.240.219 responds now. although its very slow

On Windows or Linux?

I notice the ping time on Windows is 6x slower than Linux, very odd.

[flepp_w]

Re: AccurateRip Moved to a new Home

Ok

A reboot of the router would reinialize the rip table, and is worth to try.

Sometimes in DSL routers NAT is in fact a port address translation (PAT) to route ports to an IP for using a Webcam or similar devices. Those devices should not use port 80.

What's strange that you have this bottleneck issue just on accuraterip.

First you should go to www.speedtest.net and do a speedtest of your
internet connection. It should match the speed provided by your ISP.

Netstat -s shows statistics of your IPV4 connection. Just do a copy paste of the screen.

The best would be to reboot your pc first to reset all statistics to 0.
Then do some browsing and ping on www.accuraterip.com and copy paste the netstat -s screen.

[Ney]

Re: AccurateRip Moved to a new Home

Ill post a netstat -s after next reboot. My net if fine, and I can easily hit 250+kilobyte/s from dbpoweramp.com accuraterip.com is the only problem.

I run Vista 32-bit SP1 RC. Before the server move accuraterip worked fine.
