Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

I use Debian on a server with multiple upstream internet links. Some of these links have peering point IPs.

It happens fairly often that apt-get traffic uses the source IP in a peering point range and then downloads fail.

Please consider adding a feature so I can configure apt-get to specify a source IP or interface on the server.

For example: traceroute has a -s option: "Chooses  an alternative source address."

I was about to say that specifying ip addresses for sources needs to be
solved at an RFC level (need to standardize URLs like http://foo[ip]/),
but um now I understand that you don't want to configure the IP of the
source, but the interface we send packets from.

Probably should be retitled with a less ambiguous title :D

Anyway, no idea how complex that feature is, I guess proof of
concept patches welcome.

Hi

Yes, sorry, should maybe have had title with Source _IP_address_

I think you should be able to specify a source IP when opening the tcp socket.

Would probably need to add some code for IPv4 and IPv6 cases.

It's basically a new configuration option for apt.conf and an additional
parameter in the connect() call. See https://github.com/ThomasNoll/oas
(that's a LD_PRELOAD wrapper adding this functionality to arbitrary
software, see connect.c)

Hi

I figured out a temporary workaround using ‘ip netns exec’

It works, but things like apticron will still fail.

Hi!

This ticket probably should be merged with
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=548590, but I'm not
100% sure.
