I'm having a problem with ifupdown and /etc/network/interfaces. (the default networking core for Debian?)
Specifically, I cannot have two Internet routed interfaces working properly at the same time. Whichever is the last connection to be brought up is the one that works, while the first connection cannot communicate outside of its local network. I have attached: 1) A log giving an example of the issue, with some helpful markers so the deluge of text doesn't confuse. 2) My /etc/network/interfaces file. Hopefully someone can correct me in my usage. In my current problem, eth0 is assigned to "shadowpimps" and eth1 is assigned to "away". I'm not on the debian-users list, so please CC me in any response. I do watch the archives, though. Thanks is advance for any help! Scott. -- http://quadhome.com/ - Personal webpage
