| 15:06.46 | josephnexus | hello everyone |
| 15:06.56 | goozbach | mroning |
| 15:06.58 | josephnexus | I was hoping someone could help me an interesting situation |
| 15:07.26 | josephnexus | I've got an ubuntu server here with two nics, and I've got two seperate ISPs. I'm wanting it to be able to use both ISPs. |
| 15:07.54 | josephnexus | I know it isn't as simple as assigning the static IPs to each interface, because then it won't know when to route out of each interface |
| 15:08.10 | josephnexus | I need to be able to ssh in on either interface, as well as need apache serving pages on each interface |
| 15:08.21 | josephnexus | anyone have any ideas or pointers? |
| 15:09.44 | josephnexus | i would set up a load balancer in front, but that's ok |
| 15:09.51 | josephnexus | I only need inbound traffic to work on both interfaces |
| 15:09.54 | josephnexus | not outbound |
| 15:10.30 | josephnexus | when I had both interfaces active, I could get out to the net on the server, but I couldn't ssh in on either interface, one would time out (the old interface) and the other would respond, but would never let me authenticate, even though I'm sure I put in the right password |
| 15:10.41 | goozbach | then set them up with the static network |
| 15:10.45 | goozbach | but omit a route |
| 15:10.59 | goozbach | and set a global system route on just one of the interfaces |
| 15:11.05 | goozbach | that should be the first part |
| 15:11.22 | goozbach | you connected, but not authenticated |
| 15:11.24 | goozbach | ? |
| 15:11.38 | josephnexus | but then will traffic coming in the other route know to go back out the other route? |
| 15:11.52 | goozbach | maybe |
| 15:11.59 | fugue88 | josephnexus: When you were testing this, were you physically isolated to just one of the nics? |
| 15:12.00 | goozbach | there is a second step I'm trying to remember |
| 15:12.15 | josephnexus | fugue88, what do you mean? |
| 15:12.16 | goozbach | about link affinity or somesuch |
| 15:12.56 | fugue88 | It seems like IP (the protocol) ought to be able to handle this, where some packets might flow through one route, and some through a different one. |
| 15:13.09 | josephnexus | it does |
| 15:13.16 | josephnexus | and you would think it would know from which route they came |
| 15:13.22 | fugue88 | But if you're testing this by connecting directly to one of the nics, then you could be missing packets from the other nic. |
| 15:13.37 | josephnexus | fugue88, I was going out through the internet to test it |
| 15:13.40 | fugue88 | josephnexus: But which route it came from wouldn't matter, is what I was thinking. |
| 15:13.43 | josephnexus | both nics lead to the internet |
| 15:14.02 | josephnexus | fugue88: it matters for people who have routers expecting the return packets from a certain IP |
| 15:14.10 | fugue88 | josephnexus: So you had paths through both, I don't know why it wouldn't work, my knowledge is lacking... :( |
| 15:14.24 | fugue88 | Who cares about such people??? |
| 15:14.33 | goozbach | josephnexus: this is the multiple return path problem |
| 15:14.42 | josephnexus | anyone who wants people with home routers to be able to connect |
| 15:14.45 | josephnexus | :-P |
| 15:14.49 | goozbach | and there is a solution |
| 15:14.56 | josephnexus | get two servers? |
| 15:14.59 | josephnexus | :P |
| 15:15.05 | fugue88 | Get 1 ISP. |
| 15:15.07 | goozbach | I'm dusting off old boxes of memories in my brain |
| 15:15.08 | fugue88 | :P |
| 15:15.09 | goozbach | please hold |
| 15:15.20 | goozbach | my attic is cluttered |
| 15:15.34 | josephnexus | fugue88, i want to have two isps, because we'll be adding another A record to the dns, so both will be utilized, and if one goes down, we pull one of the A records |
| 15:15.45 | josephnexus | it isn't pretty, but it is cheap |
| 15:15.48 | josephnexus | :-P |
| 15:16.05 | josephnexus | which is the driving requirement in this case |
| 15:16.05 | goozbach | that it is |
| 15:16.21 | goozbach | josephnexus: man iptables may have some help |
| 15:16.33 | josephnexus | have you seen that manual? |
| 15:16.39 | josephnexus | it's freaking huge!!!! |

| 15:19.57 | goozbach | those two links seem close to what you need |
| 15:20.04 | goozbach | the first part still stands |
| 15:20.12 | josephnexus | the first part? |
| 15:20.20 | goozbach | (*NO* per-interface, nor global routes) |
| 15:20.25 | josephnexus | ok |
| 15:20.42 | goozbach | and remember |
| 15:20.54 | josephnexus | and after I get all of this set up, since debian is awesome, I just do a /etc/init.d/networking restart yes? |
| 15:21.03 | goozbach | if you can't reboot the box, and have it come back in the state it is supposed to be, you're not done :) |
| 15:21.16 | goozbach | (I learned that one the hard way... lots of times) |
| 15:21.23 | josephnexus | yes, but I don't want to restart |
| 15:21.26 | goozbach | josephnexus: in a nutshell yeah |
| 15:21.47 | goozbach | josephnexus: I'd suggest scheduling some downtime to test it anyhow |
| 15:22.10 | goozbach | and if you're really worried about uptime of a website you shouldn't be on a single server :P |
| 15:22.17 | josephnexus | yup |
| 15:22.26 | josephnexus | we're slowly improving them |
| 15:22.32 | josephnexus | just takes time |
| 15:22.55 | goozbach | and if you ever decide that you want to spend money to do your load balancing F5 networks is the best |
| 15:23.00 | goozbach | super powerful |
| 15:23.05 | goozbach | but super expensive |
| 15:23.28 | goozbach | however, they're almost essential for a multi-million dollar web infrastructure |
| 15:24.03 | josephnexus | yeah |
| 15:24.07 | josephnexus | this, this right here |
| 15:24.21 | josephnexus | this web infrastructure is valued not in billions |
| 15:24.40 | josephnexus | not in million, or thousands really, or even hundred, but valued in the tens of dollars |
| 15:24.46 | josephnexus | TENS OF DOLLARS! |
| 15:25.20 | goozbach | well, when your tens, becomes hundreds of thousands, look at f5 |
| 15:25.50 | fugue88 | josephnexus: Strategic corporate asset, that! |
| 15:25.52 | josephnexus | ok |
| 15:25.56 | josephnexus | i'll keep them in mind |
| 15:28.17 | goozbach | josephnexus: not quite the same problem, but this project may inspire you: http://code.google.com/p/muggles/ |
| 15:28.37 | josephnexus | does it help networks that are valued in the tens of dollars? |
| 15:28.47 | goozbach | could do |
