What's adding ":8090" to all my URL's?

I have a very strange networking problem that only occurs with a login type wireless connection at my school, but never with a wired connection there, or other types of wireless connections, encrypted on unencrypted. What use to work a few weeks ago fine, taking me to the login page at "https://bs5000.lehman.cuny.edu/login.pl?action=paint;source=172.16.8.221;desti nation=http%3A%2F%2Fwww.macosxhints.com%2F%3F;r=OGoe2xc5481" whenever I typed in any random URL (www.macosxhints.com in this case), now instead appends ":8090/www.lehman.cuny.edu" to any address so instead I'd go to "www.macosxhints.com:8090/www.lehman.cuny.edu" in this case. Lehman.cuny.edu is my school's domain.

It still works fine for other people at school, even on Macs. The only thing I can pinpoint I might have changed around the time it stopped working is installing Parallels and a DynDNS transponder, but I've uninstalled both of those, taken all the StartupItems out of my /System/Library and /Library folders, restarted, no change. It even does this for newly created test users with nothing installed. I've talked to Apple about it and they thought it had to do with Parallels, but uninstalling that didn't help. They said just do an erase and install of the system but I have nowhere to store all my data in the meantime and there should be a simpler solution. 😟

I've done a grep of the entire system for "8090" and can't find anything that jumps out. I can send the dump of that if you'd like. I also deleted all my certificates at my school's IT dept's suggestion, since the login process does give you certificate, but still didn't help.

I don't have any other networking software like Little Snitch that I can think of installed. Any ideas on this vexing problem?

Thanks in advance.

Ah, yes, I forgot to say that I was using Privoxy, the ad scrubber which runs as local proxy server, but I have disabled that, turned off proxies, and killed this process, and I still have the same problem. This runs on port 8118 anyway.

How do I tell what might be running on port 8090? Netstat in Network Utility doesn't seem to show anything, but I don't see an easy way to list which ports are in use for what. Do I need Little Snitch or something. I am not running Apache or another web server on this machine.

Thanks for the suggestions.

Trust me... Gnarly knows much more about this than I do, so don't put too much into what I say. 🙂

I'm thinking nothing is using 8090, but that some APP has set that, (Peer to Peer, Gaming, Acceleration SW, etc.), Proxy to be added. Not sure where it wuld be if it doesn't show in Network.

In Network Utility>Port Scan, does it show 8090 open for 127.0.0.1?

You are wrong, Aqua. I don't hardly know anything about it. Except that once I had a website on Server X that would reroute http to port 8080 under certain circumstances. It was a bug in the software so it is documented online somewhere. Ports 8080 and 8090 are common alternatives to the default http port 80, and many webmasters set that as their Apache listening port to foil dictionary attackbots that hit the default port.

As to solving the OPs problem, I have no idea. I have heard of Privoxy but don't know what it does.

The thing is, blocking any URL in the hosts file reroutes the requested item to an error page. If the item is in a frame or an embedded object, you only see the upper left corner of the page in that small square. If Apache is running you can use the feature to add a cool graphic there which appears instead of the advertisement. I have a striped apple with "Eat Me" underneath, which cracks people up.

I'm not sure whay I am saying this, but it does sound like some firewall is rewriting URLs for you much the same way that the hosts file does.

I'd try searching these 3 files for the text 8090...

/Users/nnnn/Library/Preferences/com.apple.internetconnect.plist

/Library/Preferences/SystemConfiguration/preferences.plist

/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist

If you can't, then you might try trashing them or dragging them to the Desktop, (for replacement if it doesn't work), reboot and set up all your network settings again.

Thanks for the inciteful suggestions guys. No sign of 8090 in any of those three files BDAqua. I've even grepped my entire directory structure for 8090 in desperation, and you can find the output of that here;

The one thing I'm suspicious of is the FMEObjects.framework. Anyone know what that is for?

I am using Safari mainly but this happens both with Safari, Firefox, and I believe even Mozilla. I occurs with a newly created test user as well, so It seems to be system wide. But I see no where in the Safari prefs to set proxies. I was using SAFT but I disabled that and the same thing occurs.

Thanks again!
