| apb1963 | 16.04 Is it possible to setup a dhcpd server with 1 ethernet card, or must I have 2? | 19:19 |
|---|---|---|
| apb1963 | I'm running into this error: No subnet declaration for enp5s0 (external IP redacted) and I can't help but wonder if it's because I don't have two ethernet cards. | 19:23 |
| apb1963 | Or if perhaps this error " Not configured to listen on any interfaces!" is more relevant even though it comes after the above. The odd thing is, I do in fact setup the Listen device in /etc/default/isc-dhcp-server | 19:27 |
| apb1963 | Yeah... I'm starting to think it's because I only have the one card... so the external address is not on the same network, so it has no device to use on the local net. | 19:29 |
| apb1963 | Which is of course the network I need to allocate IPs on. | 19:30 |
| apb1963 | Maybe I can get the one card to respond to both internal and external addresses? | 19:31 |
| apb1963 | I'm sure there's a way to do that. OK, thanks! | 19:31 |
| _KaszpiR_ | apb1963 sure you can have dhcp with 1 card | 19:36 |
| _KaszpiR_ | and it looks liek you're missing config section for the subnet | 19:36 |
| _KaszpiR_ | you may also vlans to separate public and private network | 19:37 |
| _KaszpiR_ | *also use vlans | 19:38 |
| _KaszpiR_ | but it may require additional network configuration on the switch level and so on | 19:38 |
| apb1963 | _KaszpiR_, That's just it... I'm not missing a config section for the 192.168.1 network. But the card is an external IP. My router died and I figured I'd just setup the software to replace it. | 20:20 |
| apb1963 | i'm not all that familiar with vlans and I suspect it's overkill for my home network. | 20:21 |
| apb1963 | So, it wants a config section for the IP associated with the card - an external address. From the network's point of view, that same machine is NOT on the 192.168.1 network. | 20:23 |
| apb1963 | Which I suspect is why it's giving me the errors. | 20:23 |
| apb1963 | Because there is no interface associated with that subnet. | 20:24 |
| apb1963 | And so, I'm guessing I need to use a virtual IP for the internal address. | 20:24 |
| apb1963 | But then it occurred to me that I have a wireless card installed. And that's where I'm at now... looking at how to set the wireless card for the internal subnet. | 20:25 |
| apb1963 | Oh... I was looking at how to setup virtual IPs... it requires disabling network manager, or modifying one of its file after first messing with the GUI - I need a pure cli solution. | 20:26 |
| apb1963 | Which is why I'm leaning towards two cards. | 20:27 |
| _KaszpiR_ | apb1963 better get second card | 20:28 |
| _KaszpiR_ | especially if you do not have a router | 20:29 |
| _KaszpiR_ | nor manageable switch | 20:29 |
| apb1963 | no router, no switch... well there's a router from my ISP but it's a black box. | 20:34 |
| apb1963 | _KaszpiR_, by second card, you mean a second ethernet card or is the wireless card sufficient? | 20:34 |
| _KaszpiR_ | I'd sujggest second ethernet card | 20:35 |
| _KaszpiR_ | unless all the other devices are wireless only | 20:35 |
| apb1963 | Yes, except one is both wired & wireless... Once I bring it up, it will be swapping roles with this machine. | 20:36 |
| apb1963 | I'm unclear as to why it's an issue. They protocol should really be relevant as long as they can talk to each other. By protocol I mean tcp/ip. | 20:37 |
| apb1963 | sorry, that last sentence was confused. | 20:38 |
| apb1963 | I'm unclear as to why it's an issue. As long as they both speak the same protocol (tcp/ip) then whether wired or wireless I wouldn't expect to make a difference. Or am I wrong? | 20:39 |
