Cant listen to Stations not on home page

[r3c0n]

Let me start by saying, no... I do not know everything about networking and related issues. However, I succesfully started a server from home last night within 30 minutes. After reading the forums a bit I realized that I am not the average idiot, for tons of people have been trying for days/weeks with no success, so after 30 minutes of tinkering I was live and broadcasting. My friend from a remote location was able to stream from me, and I also was able to stream to my other PC on the same lan using my internal IP (ie. 192.168.0.101:8000).

All that said...
I am here at work trying to connect to various shoutcast streams. I have been streaming for years here from work with no problems. As of the last few days I can not connect to any server not listed on the shoutcast home page. I have tried several, several different streams. The only streams I can connect to live on the home page, all others time-out. Any ideas???

Obviously the first respoonse would be well they blocked the ports on ur corporate firewall. All thats good and well but I ask then why can I connect to thoes stations listed on the home page, but not any other server that I search for or switch genres to?

Do those stations listed on the home page have a special privilage and use a widely used/open port such as 80? Is there anything special about them that would allow them to pass thru any potential firewalls? As i've stated before I have listened to streams from work on a daily basis for years, infact I am currently listening to a stream from the home page. I have even compared the link from the home page to a link not on the home page and they are identical (minus the station ID ofcourse).

ex:
http://www.shoutcast.com/sbin/shoutc...e=filename.pls
http://www.shoutcast.com/sbin/shoutc...e=filename.pls

here is an example of a link from the home page and a link fomr a station not on the home page. The first one I can connect to, the second I cannot!!!

please help.

Thanks

I think many of the top 25 streams are on AOL bandwidth using Ultravox and I might be wrong here but I would think they are likely port 80 as well.

If you want to see if it's a firewall issue try my 192k stream below then try the 128k. The 192k uses HTTP port the 128k's don't (except for one). You'll know for sure then.

Thanks for the reply. I think the issue is definately becuse of port blocking. What a coincidence that the "Big" Stations use port 80.

So for all of those reading this and can do anything about it, get the indie stations and not so "Big" stations to switch to a more widely open port so us guys at work can tune in still.

My next mission, gain root on one of our linux boxes and open up a few ports .

With todays security climate it's almost a necessity to run feeds that are port 80 accessable otherwise I would seriously hinder people from listening who are at universities and corporations. I run both - HTTP accessable feeds that can get through firewalls and feeds on nonstandard ports for those who can access anything.

It's that old 'two birds with one stone' system and it insures anyone can listen. Anyone who doesn't do it is likely cutting off a decent amount of people who could never tune it because of universities and corporate firewalls.

You can get around this using proxy servers which allow you to pipe out on port 80 from the firewalled location through another computer (yes, even your home PC) and then to the nonstandard port. Some searching on Google may yield some useful results.
