ISP Blocked???

[isuzurover]

I tried to access AULRO at work today and got this message:


vBulletin Message
You have been denied access to this forum. The reason is that you are visiting us from a place that has been blacklisted as an Open Proxy. You have to fix this, and return.

If you want to know exactly where you are blacklisted, go see TornevallNET Proxy and Abuse-filtering Project (http://www.tornevall.net/cgi-bin/ip.cgi).

I tried following the links, but to no avail...

Any ideas???

Type "Open Proxy" into Google.

From what it says there under Wikipedia - it's possible that your server at work may have been infected by some sort of virus, opening it to access by anyone on the internet. Might pay to either run a good anti-virus scan on it, or have your IT guru's (if you have any) look at it.

I had something similar happen on my laptop not long ago. Ended up having to update definitions file in AVG (the anti-virus I'm running) and then re-run AVG. This found a couple of files that should not have been there. Have had no problems since.

Hope this helps ...........

Good luck trying to get it fixed. Our email provider had one of their servers blacklisted as an "open proxy". We became aware of this when several of our emails (to clients using Telstra services) came bouncing back with that error. We eventually found out that the blacklisting was a mistake, but the process to have it removed from the blacklist was never resolved.

Apparently ISPs (in this case good old Telstra) subscribe to companies that compile these blacklists. Even if you can convince the ISP that your server has been wrongly blacklisted, you still have to convince the blacklisting company and they were not easy to deal with in this case. Our mail provider was told that the server would not be removed from the blacklist until they provided evidence that the issue (open proxy) had been fixed. They couldn't do this as it was an error and had nothing to do with an open proxy! So the two reached a stalemate and in the end everyone gave up and they just migrated all the affected users to a new server.

doesnt appear to be listed now....

the problem is the guys that attack sites like this use open proxy servers to try and hide their real identity when trying to break in to the sites.

comes down to inept service providers that dont how how to secure their own servers so they get blacklisted until they do secure their servers and that saves the rest of the net heaps of trouble.

that said sometimes you can get into one of these lists by accident and it can take some effort to get your self out of some of the real zealot services.

??? It was still blocked today. Will have to get onto the IT people tomorrow. Usually we have good security, but who knows what some of those pesky students might have been doing....

well I can access on the work lan, but whatever the changes were from about 7-10 days ago meant I couldn't access via 3G on my phone (had the same errors reported above). Now since Inc has been playing around again, my phone access is back...

I'm blocked out again - this time from home and my phone...

but I can access from work (Same ISP as at home!!)

weirdness... Inc, I sent you an email last night to your davecandoit address, not got a reply as of a few hours back, but given I can access from work, would love to know if there is anything I can do to sort this out?

[incisor]

i replied earlier today..

it should be fixed now... but i think it sucks that this needs to be turned off.

gotta say there are some bloody woeful isp's out there these days....

must have more money than sense to have open proxies .... or they dont pay for data...

[incisor]

I have one of those inept ISPs - their name is Optusnet!

they are as useless as bigpond (actually they seem worse these days) and a few of the other big names in the .au isp industry.

the big fellas are all happy to not give a toss as you are on data capped plans ..

most smaller isp's have much better set ups as they personally have to pay for data they use so ensure no one steals theirs....

if the big 5 in au went to the trouble of securing their open proxies and other such devices they leave open, you would see about a 30% decrease in traffic on the au backbones according to the last data i saw...

thanks for the reply inc - I'm still at work so haven't seen it yet...

is this specifically related to the ISP itself? or is it possibly due to malware/spyware whatever running on my individual PC?

is specifically open proxy related.

that is usually an isp issue BUT if you run a proxy server such as squid, you could find your way into the blacklists if it is misconfigured.

universities and the big 5 isps are the main culprits generally speaking.

hmm how about peer to peer torrent programs? could that be it?
