I’ve had a problem getting Eclipse, and specifically the Android SDK to run on my Debian laptop for over a year now. I’ve generally just VNC’ed to a more powerful box and ran it there.

The problem I had was that most network operations in eclipse would fail with network unreachable. Not a big deal for day to day things, but you need the network to install the Android SDK kits and install Eclipse plugins.

I had been trying to strace things to figure out what it was, and finally found it:

connect(26, {sa_family=AF_INET6, sin6_port=htons(443), inet_pton(AF_INET6, "::ffff:74.125.95.91", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = -1 ENETUNREACH (Network is unreachable)

Huh, it’s doing IPv6 connections. GOOD. But, it hasn’t set the right IOCTL on the socket to permit IPv4 mapped connections to work, and on Debian, the bindv6only is now not set.
