| Bakgat | hi all | 04:01 |
| Bakgat | anyone here well versed in networking on an ubuntu system (interfaces, shorewall, etc) | 04:02 |
| Pygi | Bakgat: what exactly do you need? | 04:02 |
| Bakgat | Hi Pygi | 04:02 |
| Pygi | Hi Bakgat | 04:02 |
| Bakgat | I've set up a mail server based on instuctions from http://flurdy.com/docs/postfix/#install_pack | 04:03 |
| Bakgat | very detailed & helpfull | 04:03 |
| Bakgat | Everything seems to have gone ok (took me better part of a whole day to set up). but i ca't seem to access the networks. | 04:04 |
| Bakgat | I originally set it up with only a single NIC, detailed in /etc/network/interfaces | 04:04 |
| Bakgat | i've atempted to fill in as much detail in /etc/shorewall/* , but i seem to have missed something, cause if i ifconfig, i only c the loopback | 04:05 |
| === ivoks [n=ivoks@ubuntu/member/ivoks] has joined #ubuntu-server | ||
| Bakgat | this box is going 2 act as mail & web server from a dnz zone. i have a seperate box that acts as a router/firewall/proxy/etc | 04:06 |
| Bakgat | my firewall will transparrently route traffic & handle security from internet, wired network, wireless network & dmz, but that's a topic 4 another day | 04:08 |
| Bakgat | where do we start? | 04:08 |
| Bakgat | the mail service & some other services seem ok | 04:09 |
| Bakgat | i just can't get the nic to gell | 04:09 |
| === mgalvin [n=mgalvin@ubuntu/member/mgalvin] has joined #ubuntu-server | ||
| Bakgat | Pygi, u still there? | 04:15 |
| Pygi | Bakgat: not really, and yes :-/ | 04:16 |
| Bakgat | so, what do u suggest? | 04:21 |
| Pygi | tried restarting "networking"? | 04:23 |
| Bakgat | yip | 04:24 |
| infinity | You're configureing your network in /etc/network/interfaces? | 04:24 |
| infinity | And does "ifup eth0" (or whatever interface) work? | 04:25 |
| Bakgat | yip. will give detail soon | 04:25 |
| Bakgat | nope | 04:25 |
| infinity | Do you get any errors? | 04:25 |
| Bakgat | networking/interfaces set to dhcp 4 now | 04:25 |
| Bakgat | checking log not | 04:25 |
| Bakgat | now | 04:26 |
| ivoks | ifconfig | grep eth0 | 04:26 |
| ivoks | check out if kernel recognized your nic as eth0 | 04:26 |
| ivoks | or maybe some other nic is eth0 (this is not so rare as it seems) | 04:26 |
| Bakgat | ok. where/how do i do that? | 04:26 |
| Bakgat | ifconfig only lists loopback | 04:27 |
| ivoks | in konsole/terminal | 04:27 |
| infinity | "ifconfig -a" to show interface that aren't up. | 04:27 |
| Bakgat | ok. hang on | 04:27 |
| infinity | s/interface/interfaces/ | 04:27 |
| ivoks | may bad... | 04:27 |
| ivoks | dmseg | grep eth0 | 04:27 |
| ivoks | not ifconfig :) | 04:27 |
| Bakgat | cool! sees all nic, just not assigning adddr. | 04:28 |
| Bakgat | not seeing dmseg cmd | 04:28 |
| infinity | Kay, then your /etc/network/interfaces is wrong. :) | 04:28 |
| ivoks | mii-tool? | 04:29 |
| Bakgat | mii-tool, check | 04:29 |
| Bakgat | eth0: Bad addr, eth1 op not supp | 04:29 |
| Bakgat | no MII interfaces found | 04:30 |
| Bakgat | bad network/interfaces? | 04:31 |
| ivoks | eth0: bad addr? | 04:34 |
| Bakgat | will set interfaces 2 static in interfaces | 04:34 |
| ivoks | huh? | 04:34 |
| ivoks | your eth0 gets ip from dhcp? | 04:34 |
| Bakgat | mii-tool reports SIOCGMIIPHY on 'eth0' failed: Bad Address | 04:35 |
| Bakgat | for now | 04:35 |
| Bakgat | wil set to static | 04:35 |
| ivoks | dont | 04:35 |
| ivoks | do ifdown eth0 | 04:35 |
| ivoks | and then manually get address from dhcp | 04:35 |
| ivoks | dhclient eth0 | 04:35 |
| Bakgat | sit0: unknown hardware addr type 776 | 04:36 |
| Bakgat | do u have skype addr? typing's a schlep | 04:37 |
| ivoks | nope | 04:37 |
| Bakgat | ok | 04:38 |
| ivoks | forget about sit0 | 04:39 |
| ivoks | what did it tell you about eth0? | 04:39 |
| Bakgat | no-go. hardware. let me just reboot with single nic | 04:39 |
| Bakgat | sweet! got a DHCP lease (192.168.0.232), but not I need to set it up as static (192.168.0.100/255.255.255.0 for test & config, but 192.0.0.10/255.255.255.0 in production) | 04:43 |
| ivoks | i told you to run dmsg | grep eth0 | 04:44 |
| ivoks | that other nic was eth0, and the second one was eth1 | 04:44 |
| Bakgat | disabled eth1 in bios, dmesg picks up on eth0. gives hardware id, mac, irq, link up, no ip6 routers | 04:46 |
| Bakgat | i can c the apache server via http, but other services to working (phpmyadmin, squirrelmail) | 04:47 |
| Bakgat | *other services not working* | 04:47 |
| infinity | Bakgat: dID YOU JUST SAY 192.0.0.10? | 04:48 |
| infinity | Bakgat: Erm, caps lock, sorry. | 04:48 |
| infinity | Bakgat: But, I hope that was a typo. 192.0.0.0 is a routable subnet, not a private one. People own that IP address. :) | 04:48 |
| ivoks | infinity: people think 192.x.x.x is public :) | 04:48 |
| ivoks | infinity: i saw one big company with 192.192.x.x for private network :) | 04:49 |
| Bakgat | once in production i'll change the networkning & shorewall. i'm setting up the server @ home office | 04:49 |
| infinity | ivoks: You mean private, I assume. :) | 04:49 |
| ivoks | infinity: right :) | 04:49 |
| infinity | Bakgat: In the 192 space, ONLY 192.168.0.0 is private, no other 192.x subnets. | 04:49 |
| infinity | (If you really need more IPs than a class B, though that seems unlikely, use 10.0.0.0, which is entirely private) | 04:50 |
| ivoks | Bakgat: if you need class A, take 10.x.x.x | 04:50 |
| ivoks | lol | 04:50 |
| Bakgat | i'm planning the networks from my firewall's PoV into 3 seperate network classes. DNZ in class C, wired network class B, wireless class A. have i got it wrong? | 04:50 |
| infinity | And I always forget the other one... 172.something? | 04:50 |
| infinity | Bakgat: Almost certainly. | 04:51 |
| ivoks | infinity: that one i froget too... | 04:51 |
| ivoks | Bakgat: you need three class C networks | 04:51 |
| infinity | Well, or three much smaller networks. | 04:51 |
| Bakgat | been a while since i've done subnetting, so i'm a bit rusty. used a subnet calc to determine networks | 04:51 |
| infinity | classless subnetting is the future. | 04:51 |
| ivoks | Bakgat: for example, 192.168.1.x, 192.168.2.x and 192.168.3.x | 04:51 |
| ivoks | why bother with subnetting? | 04:52 |
| ivoks | in this case... | 04:52 |
| Bakgat | i'd like to seperate networks by subnets so that one network cant accidentaly stumble upon another | 04:52 |
| ivoks | subnetting is ok only for public subnets | 04:52 |
| maswan | infinity: 172.16 - 172.31 | 04:53 |
| ivoks | maswan: right :) | 04:53 |
| infinity | maswan: Thanks, you ever-loving fount of useless knowlege. :) | 04:53 |
| maswan | We use that here, actually | 04:53 |
| infinity | Sure, use the one that's hardest to remember. Makes sense. | 04:53 |
| ivoks | :) | 04:54 |
| infinity | I always use 10.0.0.0, because I'm a lazy typist. :) | 04:54 |
| maswan | Since 10.x is used by the networking people and 192.168 is used alot | 04:54 |
| maswan | Ok, as long as the campus networking people do things right, we never notice. But... ;) | 04:54 |
| Bakgat | ok. lets assume this server will sit @ 192.168.0.10/255.255.255.0 | 04:54 |
| ivoks | Bakgat: that's ok | 04:54 |
| Bakgat | i'd still like to put my other networks on seperate subnets, but that's an exercise for another day | 04:55 |
| ivoks | Bakgat: ? | 04:55 |
| ivoks | Bakgat: put the other one in 192.168.1.x | 04:55 |
| ivoks | and there you have it | 04:55 |
| Bakgat | I'll go mod my networks/interfaces file quiqly. cool? | 04:56 |
| ivoks | on different subnets, one can't go to the other | 04:56 |
| Bakgat | that's the idea | 04:56 |
| infinity | Well, not really true. | 04:56 |
| infinity | If they're the same physical network, you can easily hop from one to the other. | 04:56 |
| ivoks | infinity: what's true these days? :) | 04:56 |
| Bakgat | the router/firewall must handle routing (i use IPCop) | 04:56 |
| infinity | But, shhh. | 04:56 |
| ivoks | infinity: nothing can prevent that :) | 04:56 |
| Bakgat | i'm looking @ LDAP on a seperate server, but also an exercise for another day | 04:57 |
| infinity | I was rather surprised to discover that my AUD 150 hunk of junk DSL modem/router actually does VLAN switching. | 04:57 |
| infinity | Not that I need VLANs at home, but neat anyway. | 04:57 |
| ivoks | ah, i'm using wifi broadband :) | 04:58 |
| Bakgat | ok, so I set my networks/interfaces to static as detailed in http://flurdy.com/docs/postfix/#install_pack | 04:59 |
| === mgalvin [n=mgalvin@ubuntu/member/mgalvin] has joined #ubuntu-server | ||
| Bakgat | now what | 04:59 |
| Bakgat | net to fix static 2 nic | 05:00 |
| Bakgat | do I need to set up shorewall next? | 05:00 |
| Bakgat | would eth0 b net or loc on shorewall in the current stup | 05:01 |
| Bakgat | would eth0 b 'net' or 'loc' on shorewall in the current setup? | 05:01 |
| === ivoks doesn't use wizards :) | ||
| Bakgat | cool. set up my dhcp server to issue lease to server based on mac (will lock down later) | 05:10 |
| Bakgat | now, how do I configure my shorewall files (bit confising) | 05:12 |
