| arrrghhh | probably the worst time to ask for help, but does anyone have experience troubleshooting TFTP issues? | 04:05 |
|---|---|---|
| twb | Yes; what is your real question. | 04:06 |
| twb | Hint: use curl -v as your client | 04:06 |
| arrrghhh | sorry i didn't ask a real question | 04:06 |
| arrrghhh | curl -v... | 04:06 |
| arrrghhh | i'm using tftpd-hpa | 04:07 |
| arrrghhh | and it refuses to start | 04:07 |
| arrrghhh | i could only find an entry in /var/log/daemon.log | 04:07 |
| twb | Does it say why? | 04:07 |
| arrrghhh | said "init: tftpd-hpa main process terminated with status 2 | 04:07 |
| twb | OK so it's an upstart job | 04:07 |
| twb | upstart throws away stderr so you can't see why it died | 04:07 |
| arrrghhh | but if i try to start it again, it is convinced it's running | 04:07 |
| arrrghhh | i can't figure out how to start it manually either... | 04:08 |
| arrrghhh | i would assume there's a way to start it manually | 04:08 |
| twb | Sure, read /etc/init/tftp-hpa.conf | 04:08 |
| twb | Also pastebin it so I don't have to look it up | 04:08 |
| arrrghhh | that conf file? | 04:09 |
| twb | btw IME it is MUCH easier to roll out dnsmasq than dhcpd+bind+tftpd | 04:09 |
| twb | arrrghhh: yes, pastebin /etc/init/tftpd-hpa.conf or whatever it's called | 04:09 |
| arrrghhh | yea, it seems dnsmasq would be easier | 04:09 |
| arrrghhh | perhaps i should go with it | 04:09 |
| arrrghhh | i don't really care, i just need dhcp + tftp | 04:09 |
| twb | Then definitely dnsmasq is easier | 04:09 |
| arrrghhh | ok i'll start over with that | 04:09 |
| arrrghhh | lol i think i figured out the problem. oh well, if dnsmasq makes my life easier i'll go with it. | 04:12 |
| twb | http://paste.debian.net/150122/ is my dnsmasq.conf; the tftp options are near the middle | 04:15 |
| twb | Mine is pretty riced-up, you can skip most of it | 04:15 |
| twb | The CNAMEs are in there instead of /etc/hosts because they're for servers with dynamic IPs | 04:17 |
| arrrghhh | twb, so any tips on why dhcp isn't working now....? | 04:38 |
| arrrghhh | not even sure what to troubleshoot, since it's all in one package | 04:38 |
| arrrghhh | twb, sorry if i missed your response, networking issues lol | 04:39 |
| twb | arrrghhh: is dnsmasq running? Did you tell dnsmasq to serve DHCP? | 04:40 |
| arrrghhh | yes and yes | 04:40 |
| twb | IIRC the default config file only serves DNS | 04:40 |
| arrrghhh | dhcp-range=192.168.0.200,192.168.0.250,255.255.255.0,12h | 04:40 |
| arrrghhh | in dnsmasq.conf | 04:40 |
| twb | OK run dhclient -v and see what reponse you get, if any | 04:40 |
| arrrghhh | and ps -A |grep dns shows it running | 04:40 |
| arrrghhh | ok | 04:40 |
| twb | As ss or netstat if bootps is bound by dnsmasq | 04:40 |
| twb | Read the logs | 04:40 |
| twb | You know, all the usual debugging things | 04:41 |
| arrrghhh | well i've never troubleshot dnsmasq before | 04:41 |
| twb | Those are standard things to debug any network service | 04:41 |
| arrrghhh | dhclient -v has some output, but didn't really show anything helpful | 04:41 |
| arrrghhh | sorry, still learning how to debug network services. | 04:42 |
| arrrghhh | is 53 dhcp? | 04:43 |
| arrrghhh | i can't remember. i know udp 69 is tftp, which it is listening on | 04:43 |
| arrrghhh | also, what logs. i don't see a log for dnsmasq | 04:43 |
| arrrghhh | daemon.log has this | 04:44 |
| arrrghhh | "Dec 24 21:42:25 nas dnsmasq-dhcp[7114]: DHCP, IP range 192.168.0.200 -- 192.168.0.250, lease time 12h" | 04:44 |
| arrrghhh | so it looks like it's running a dhcp server wth. | 04:44 |
| twb | getent services bootps | 04:45 |
| twb | You might need to tell dnsmasq to syslog | 04:45 |
| arrrghhh | bootps 67/tcp | 04:45 |
| arrrghhh | is what that getent cmd returned | 04:45 |
| twb | Right, so that's the DHCP server port (except it's UDP, I think) | 04:45 |
| arrrghhh | tftp is udp | 04:46 |
| arrrghhh | i think dhcp is tcp | 04:46 |
| twb | BOOTP was an earlier standard that became DHCP | 04:46 |
| arrrghhh | either way, it appears to be running | 04:46 |
| twb | So what still isn't working? | 04:47 |
| arrrghhh | i even allowed bootps in ufw | 04:50 |
| arrrghhh | although it should allow any local traffic... | 04:50 |
| twb | Uh bootps & bootpc | 04:52 |
| arrrghhh | ok... | 04:52 |
| twb | It's an old stupid design | 04:52 |
| twb | Might be worth you going readig how DHCP works in wikipedia :P | 04:52 |
| twb | That's something I always do when rolling out a new protocol | 04:53 |
| arrrghhh | well i get the basics of dhcp | 04:57 |
| arrrghhh | but i shouldn't have to allow this crap in ufw | 04:57 |
| arrrghhh | it should already allow it thru another rule | 04:57 |
| arrrghhh | and adding both bootpc and bootps (67&68) didn't fix it | 04:57 |
| arrrghhh | i still can't get a dhcp ip | 04:57 |
| twb | How are you testing that? | 04:58 |
| arrrghhh | dhclient -v eth0 on the client pc | 04:58 |
| arrrghhh | used to work fine with dhcp3-server | 04:58 |
| twb | ok | 04:58 |
| twb | pastebin your ruleset, pastebin output of sudo netstat -nlp | 04:58 |
| twb | Er, not ruleset, dnsmasq.conf | 04:59 |
| twb | Although pastbinning "iptables-save -c" would also be a good idea | 04:59 |
| arrrghhh | urg | 05:00 |
| arrrghhh | this sucks not having dhcp. | 05:00 |
| arrrghhh | i defined resolv.conf | 05:00 |
| twb | So turn dhcp3 back on again for half an hour :P | 05:00 |
| arrrghhh | perhaps there's something else i'm missing | 05:00 |
| arrrghhh | hehe | 05:00 |
| arrrghhh | i already purged it | 05:00 |
| arrrghhh | i'll just turn it back on my router | 05:00 |
| twb | Also if you don't know, this is how you raise a manual link: | 05:00 |
| twb | ip link set eth0 up; ip address add eth0 brd + 192.168.0.2/24; echo nameserver 192.168.0.1 > /etc/resolv.conf | 05:01 |
| arrrghhh | blech | 05:03 |
| arrrghhh | why is nothing easy | 05:03 |
| twb | Because god hates you | 05:03 |
| arrrghhh | that ip address add command failed. | 05:03 |
| twb | s/eth0/dev eth0/ ? | 05:03 |
| twb | It was from memory | 05:03 |
| arrrghhh | i don't see what that command is for | 05:04 |
| twb | If you don't know ip(8) syntax yet you should learn that too | 05:04 |
| arrrghhh | i figured bring up the interface with ifconfig eth0 <ip> | 05:04 |
| arrrghhh | then resolv.conf | 05:04 |
| twb | arrrghhh: it gives you a static IP | 05:04 |
| arrrghhh | add nameservers | 05:04 |
| twb | ifconfig is for losers | 05:04 |
| arrrghhh | what's wrong with ifconfig? | 05:04 |
| arrrghhh | ... | 05:04 |
| arrrghhh | well your command didn't work, so perhaps you need to go back and re-read it. | 05:04 |
| twb | Main problem is ifconfig doesn't realize an iface can have >1 address | 05:04 |
| arrrghhh | hrm | 05:05 |
| twb | That's what that alias bullshit is -- a kludge | 05:05 |
| twb | arrrghhh: yeah you probably need "dev eth0" not "eth0" | 05:05 |
| arrrghhh | hrm ok | 05:05 |
| twb | Unfortunately the manpage isn't very helpful for newbies. | 05:05 |
| arrrghhh | this is just odd tho | 05:05 |
| arrrghhh | i can ping the gateway | 05:05 |
| arrrghhh | i can ping the server running dhcp | 05:05 |
| arrrghhh | but i can't ping the interwebs | 05:06 |
| arrrghhh | or 8.8.8 | 05:06 |
| arrrghhh | .8* | 05:06 |
| arrrghhh | connect: Network is unreachable | 05:06 |
| arrrghhh | lol, this was supposed to be the easy part of this task. | 05:06 |
| twb | Ah, mea culpa | 05:07 |
| twb | ip a add also adds a route to the local network, but not to 0/0 | 05:07 |
| twb | ip route add 0/0 via 192.168.0.1 | 05:07 |
| arrrghhh | zomg | 05:11 |
| arrrghhh | i don't think i've failed this hard in a while. | 05:11 |
| arrrghhh | ugh... damn chromebook. you limit me. | 05:11 |
| arrrghhh | oh there we go. | 05:12 |
| twb | You need to reflash it with ubuntu oneiric arm | 05:12 |
| twb | That's what I am on right now :-) | 05:12 |
| twb | 1kg netbook with 15hr battery life ftw | 05:13 |
| arrrghhh | wow that was fun | 05:19 |
| arrrghhh | and that sounds crazy | 05:19 |
| arrrghhh | 15hrs | 05:19 |
| arrrghhh | ok here's the dnsmasq.conf | 05:19 |
| arrrghhh | http://pastebin.com/Fr4sWJDD | 05:19 |
| arrrghhh | http://pastebin.com/YTdGuBQn | 05:21 |
| arrrghhh | netstat -nlp | 05:21 |
| arrrghhh | http://pastebin.com/hBiNUhV3 | 05:22 |
| arrrghhh | iptables-save -c | 05:22 |
| arrrghhh | yea, just disabled UFW and dhcp client still fails. | 05:24 |
| arrrghhh | lsof shows 67 and 69 in use by dnsmasq | 05:25 |
| arrrghhh | but nothing on 68 | 05:25 |
| twb | That all looks OK to me | 05:27 |
| twb | tcpdump on the server, see what you can see | 05:27 |
| twb | (Learn how to use tcpdump too ;-) | 05:27 |
| arrrghhh | sounds like wireshark? | 05:28 |
| twb | wireshark is the heavyweight cousin | 05:28 |
| arrrghhh | nice. ok, i know how that stuff works... again on a basic level :P | 05:28 |
| arrrghhh | any tips on what to filter on...? | 05:34 |
| arrrghhh | i usually filter by ip... doesn't seem like that'll work so well here lol | 05:35 |
| arrrghhh | i guess i could filter on port/protocol huh | 05:35 |
| twb | port 67 or port 68 | 05:48 |
| twb | Part of the reason I use tcpdump instead of tshark is I can never remember the tshark filter syntax ;-) | 05:48 |
| twb | Also obviously more useful data doing this on the server first | 05:48 |
| arrrghhh | hrm | 05:56 |
| arrrghhh | what was the last thing you read from me? i don't think it all got thru | 05:56 |
| arrrghhh | twb: ? | 06:08 |
| arrrghhh | perhaps you didn't get any of my messages, i was on a crippled machine, heh | 06:09 |
| twb | Hmm? | 06:12 |
| twb | 16:35 <arrrghhh> i guess i could filter on port/protocol huh | 06:12 |
| arrrghhh | damn, i said a lot more than that... | 06:13 |
| arrrghhh | oh well, the jist of it was tcpdump showed that the server was receiving the request | 06:13 |
| twb | *gist | 06:13 |
| twb | So on the client side, you see a DHCPREQUEST and then a DHCPOFFER ? | 06:13 |
| qman__ | arrrghhh, FYI, my DHCP exception is 67:68 udp | 06:14 |
| arrrghhh | 22:38:12.846558 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:13:72:27:68:83 (oui Unknown), length 300 | 06:14 |
| twb | It's a four-stage handshake, I forget the order | 06:14 |
| arrrghhh | i was running tcpdump on the server | 06:14 |
| arrrghhh | the client just keeps requesting | 06:15 |
| arrrghhh | and it times out | 06:15 |
| qman__ | $CMD -A INPUT -i eth1 -p udp --sport 67:68 --dport 67:68 -j ACCEPT | 06:15 |
| arrrghhh | never gets a DHCPOFFER | 06:15 |
| arrrghhh | qman__: why do you think the traffic is being blocked? | 06:15 |
| qman__ | it's a UDP broadcast | 06:16 |
| twb | Goddam it, who uses DNSSD | 06:16 |
| twb | This stupid printer won't talk to me, and the other users are talking to it via dnssd, which I am not going to install | 06:16 |
| twb | Bloody autodiscovery "easy to use" my arse, the printer already has an IP and listens on 631 but won't respond anything useful there... | 06:17 |
| arrrghhh | qman__: even with ufw disabled? | 06:18 |
| qman__ | I don't know much about UFW | 06:18 |
| qman__ | but if you sudo iptables -L and it's all ACCEPT with no rules, you're good | 06:19 |
| twb | arrrghhh: is there a firewall on the client? | 06:19 |
| arrrghhh | hrm ok | 06:19 |
| arrrghhh | twb: uhmm dhcp3-server worked on the client just fine | 06:19 |
| arrrghhh | but i don't think there is, no | 06:19 |
| arrrghhh | it's kubuntu 11.04 | 06:19 |
| arrrghhh | ufw is not enabled | 06:19 |
| twb | IIRC dhclient you can say test don't actually apply, find that option and run it on the server, that will bypass any network issues | 06:19 |
| twb | -n I think | 06:20 |
| twb | dhclient -n -v eth0 | 06:20 |
| arrrghhh | k | 06:20 |
| zastaph | Does anyone know if the CAP_NET_ADMIN section @ https://help.ubuntu.com/community/KVM/Networking is still relevant, or the bug has been fixed? | 13:12 |

| jmt | hello | 17:07 |
| jmt | which is the best dell server for installing ubuntu 10.04 LTS | 17:09 |
| MerryResistance | jmt: depends on whether you're getting a hardware RAID array or not | 17:10 |
| MerryResistance | jmt: i've got a Dell Poweredge 2500 series server, but Ubuntu/Debian don't include the drivers for the RAID card yet (mines got SCSI drives) | 17:10 |
| jmt | Actuall my idea is to build a complete ubuntu 10.04 server infrastructure including ldap+samba,proxy,file server... | 17:10 |
| MerryResistance | well any server will work if you have the linux drivers for it | 17:11 |
| MerryResistance | s hardware | 17:11 |
| jmt | oho.. | 17:11 |
| MerryResistance | *kicks his keyboard* | 17:11 |
| jmt | dell R710 is enough? | 17:11 |
| MerryResistance | ooh, field goal... :P | 17:11 |
| MerryResistance | gimme a sec i'm hitting lag | 17:13 |
| MerryResistance | i'm not sure, because i'm not sure whether Ubuntu has the drivers for the RAID controller card(s) | 17:14 |

| MerryResistance | link to said list? | 17:14 |
| jmt | one minute.. | 17:15 |

| MerryResistance | if its not on the ubuntu site i'm going to rant about how random lists shouldnt be trusted :P | 17:15 |
| jmt | http://www.ubuntu.com/certification/make/Dell/servers | 17:15 |
| Nafallo | the problem with that would be that it might be tested with every possible configuration ever... | 17:15 |
| MerryResistance | yeah what Nafallo said | 17:16 |
| Nafallo | unless it has a very very precise model number attached. | 17:16 |
| MerryResistance | jmt: that's in general. you should be OK, but i cant guarantee it'll work 100% efficiently/effectively | 17:16 |
| Nafallo | obviously, if the raid controller is on-board, that would make my point moot ;-) | 17:17 |
| Nafallo | but we might be talking about more cards than raid-controllers here. | 17:17 |
| jmt | if i go through normal dell pc,i am sure,it will 100% work | 17:17 |
| jmt | Nafallo: i need only 4 disk.that means built in raid controller card is enough.. | 17:20 |

| iToast | How come partitioning raid 1 on 2 160gb USB -> SATA Hdds is soo slow? | 18:44 |

| patdk-lap | partitioning is quick, should only take a few milliseconds | 19:05 |
| patdk-lap | now if your talking about resync of raid, that could take awhile | 19:05 |
| patdk-lap | with max speed of usb2, your talking about 3hours min | 19:05 |
| qman__ | iToast, USB is slow, I'd expect said formatting to take around an hour | 19:11 |

| giovani | raubvogel: "vlan package"? I'm confused | 21:13 |
