overwriting /etc/hosts aliases on connect

[Joe Barnett]

Binary package hint: network-manager

I have a number of aliases to 127.0.0.1 set up in my /etc/hosts files to help with development needs.

As of maverick, these aliases keep disappearing from the /etc/hosts file, being replaced by:

127.0.0.1 localhost.localdomain localhost

in addition to the machine hostname being bound to 127.0.1.1 and the dhcp supplied IP address.

is there:
a) a way to keep these aliases from getting overridden
b) another place I should be specifying them?

Could you state the steps you took to reproduce this?

This bug is confirmed, and a duplicate of bug 659872. Marking it as such.

As a temporary workaround, you can set aliases with 127.1.x.y IP addresses, those will still point back to the local machine and won't be overwritten by NetworkManager.
