Hi,

I am running IQFeed on my windows PC, but I am writing a program to connect from a linux host through TCP socket. It seems to me IQFeed is only exposing the local loopback, 127.0.0.1 as the interface. Is that the case? I tried my PC's ip address, namely, 192.168.x.y, and I am sure the firewall is already open.

Can someone please confirm? So it is now intended to accept connections IPs other than 127.0.0.1?

Thx

Due to exchange restrictions against redistribution of data, we restrict IQConnect to only allow connections from 127.0.0.1.

It appears many are asking for this, including me, as many OSX and Linux programmers would prefer to write software on the platform we are familiar with.

I think a simple solution would be to allow the IP address to be configureable, but only one address, instead of hardcoding 127.0.01. So if one configures a different IP address, then local access is not possible anymore. This should be fine with the exchanges, since then the computer on which IQFeed is running would function just like a relay station, like a router or firewall.

Relaying the data from IQFeed on one machine to another machine would be considered redistribution.

The simple solution is to run IQFeed under WINE which will allow you to install and run it under OSX and/or Linux. Customers are doing this today without any impact to performance.

However, it isn't, after all that is what every router does. And others allow this as well, for the same exchanges. I'd like to encourage you to discuss this specific solution with your providers.

Do all the utility programs, which come with IQFeed, run under WINE (on Mac OSX) as well?
