fromName() with localHostName() returns incomplete address list

[dv_]

Hello,

I am trying to get all local addresses on the host. I issue this call:

QList < QHostAddress > local_addresses = QHostInfo::fromName(QHostInfo::localHostName()).addresses();

QList < QHostAddress > local_addresses = QHostInfo::fromName(QHostInfo::localHostName()).addresses();

To copy to clipboard, switch view to plain text mode 

But the resulting list has only one entry, "127.0.1.1", even though I have a running ethernet connection with its own IP. At the very least the list should have two entries, "127.0.1.1" and the NIC's IP.

Does anybody have an idea what's wrong?

Found the cause. Debian and Ubuntu associate the hostname with 127.0.0.1 or 127.0.1.1 in the /etc/hosts file. This limits the lookup to these addresses.

Unfortunately, there seems to be no way around this
