Limiting access to a specific IP range?

Weez · 9th March 2003, 01:21

I'm setting up a shoutcast server and I need to limit listener access to a specific IP range (for example 192.168.x.x-192.168.255.255) and blocking out access to the rest of the world.

I set RIPOnly=Yes in my sc_serv.conf file, and that seems to block all listeners out just fine. But it appears I can only add single IP's to sc_serv.rip. What do I do to add a range of IP's in there? I'm running this on OSX Server 10.1.

danke, weez

You could use a text editor and a regular expression replacement.

Example using [utl=http://www.textpad.com]TextPad[/url]
1. Write out 256 lines of 192.168.X.Y
2. Replace Y with the regular expression \i(0)

You'll then have:
192.168.X.0
192.168.X.1
192.168.X.2
...
192.168.X.254
192.168.X.255
192.168.X.256

Then Replace the X in the same fashion.

Note: A simple double looping program would be easier.

Yeah you're right - that would be super easy to generate a list like that. But hypothetically, if I wanted 192.168.X.Y, it could end up being a pretty huge list. Maybe I should just be smart about it and do use ipfw or do a reverse lookup on the domain.

But that's more messing around than I have time for this weekend. If there's an easy way to do it with shoutcast's config files, I'd be all happy and jolly and shit.

Try using wildcards, so
192.168.*.1

Not sure if it'll work on shoutcast, but it normally works for a lot of web based programs
