Manual CC of an email to the author:
Are you still maintaining tsocks? I see there's not been a new release since 2002, but on the off chance you still care, I wanted to report a problem, which might be a bug, I'm not sure.
Basically tsocks worked for a particular application on one computer, but not another, and after much fiddling I finally straced the application on both machines, and saw that it was using IPV4 where it worked and IPV6 where it didn't. I don't use IPV6, and don't know how to tell that one program not to use it, so I just disabled it in the kernel (Linux 2.6.24), rebooted, and then it worked where it hadn't before.
Anyway, thought you'd like to know.
