Umm? Sure Telecom have just decided to block all port 80 traffic...

Is there are particular site? Have you checked the other Telecom threads about the caching issues some users are experiencing?

It's not clear but are you saying you are hosting a website on a Telecom provided service and incoming connections on port 80 are not working?

If it is the url in your signature...

Down for everyone says...
It's not just you! http://www.taf.org.nz looks down from here.

An annonymous proxy says..
The requested resource could not be loaded.
connect() timed out!

And I cannot connect from my Telecom connection. Tracert will not complete.

That doesn't help at all, sorry johnr...

Assuming you are hosting in a Telecom connection (since you have not told us details of this server at all), are you sure it's not a configuration problem (port forward on router) or software change (new antivirus with firewall or blocking features)?

Can you access the site from your internal LAN? If you have access to the server can you access the serve locally? Is the service running? Can you telnet from another client in your network?

Hi Lurch,

If its the site in your sig then there certainly are some issues with getting to it.

my traceroute and tcptraceroute finish at the same point:

[root@mrstrong ~]# tcptraceroute -p 80 taf.org.nz
traceroute to taf.org.nz (122.57.124.225), 30 hops max, 40 byte packets
1 10.1.1.1 (10.1.1.1) 0.399 ms 0.233 ms 0.340 ms
2 125-237-16-1.jetstream.xtra.co.nz (125.237.16.1) 18.849 ms 20.752 ms 30.236 ms
3 219-89-50-1.dialup.xtra.co.nz (219.89.50.1) 11.682 ms 13.567 ms 15.621 ms
4 * * *
5 * * *
6 * * *

I don't think its a cache issue, but something certainly isn't right with connectivity to that site.

Regards

Paul

Details :

Hosted by me

Running on my Ubuntu server box

port forwarding is enabled and pointing at the server

-----

I can telnet/SSH locally fine. I can even bring up the two websites hosted on the box locally.

I've checked everything from domains4less end and thats all pointing to the right IP.


However if I do a scan from grc.com no ports are open. Running nmap -sT localhost on the server box reports that the ports are open.

I even reset the router back to factory and started again. As I've said I've hosted a site on that box for a year or so with no issues until now.

Thanks Paul, not sure what would be stopping it. Restarted the box that it's on a couple of times. Will keep hacking away at it. Has me beat.

When you are testing from outside do you see packets arrive on the webserver?
Sounds very much like a firewall somewhere, host running one?

left the router off for 10 and switched it back on and received a different IP address, can now get through.

Might have been the other IP address, kept getting assigned the same one until now.

Runs on my linux box, was surprised as it has been chugging away for over a year. :-) Hosting a friends site too dontrademe.co.nz.

Anyway looks like it was the IP address I kept on getting assigned, left the router off for 10 and it finally gave me another IP which let traffic come through. :)

Unless you are paying the extra $20 a month for a static, or forwarding your Domains4less lookups to a no-ip server and updating that.. expect it to die lots.

Especially as they juggle IP pools etc.

He's using a dyn-dns type service from www.afraid.org, can see it when you do a dig +trace on the domain.

So i would assume that Lurch had his system setup to update the dynamic service, otherwise being assigned a new IP would not result in his site working.

Of course non of that explains why it didnt work...

Yep using inadyn on the Ubuntu box to update the dynamic ip now and then, every 20 minutes or something to that affect as a cron job.

Everything was blocked on the old IP, but managed to get a new IP by switching the router off for 10 minutes and powered it back up and was away laughing.

No idea why it would have been blocking everything on the old IP, was working fantastic for over a year.

Will just put it down as a mystery and move on :-) Thanks again Paul, a voice of reason amongst the noise :-)
