sarnoldyeah; but containers can overprovision even further because everyone shares the same kernel, probably shares libc6 and so forth...00:00
mvhentenok let me look around in their web panel thing00:02
mvhentenI might now know where to start looking...00:02
mvhentenparralells...00:03
mvhententhing is00:05
mvhentennmap tells me smtps is closed00:05
mvhenteni guess because ufw is not running00:05
mvhentenenabled00:05
mvhentenok i'm gonna contact the hoster. maybe I can upgrade the kernel00:08
mvhentenseems like that could solve the problem00:08
sarnoldthey may just be blocking standard smtp00:09
mvhentenand explain why every hit on google refers to issues around 2009~201000:09
sarnoldit wouldn't hurt to have a converation :) hehe00:09
mvhentenyeah, trying to use smtps actually00:09
mvhentenreally sucks using mutt over ssh00:09
mvhentenhm.... plain old iptables don't work either00:20
mvhentenmust be something larger at work00:20
mvhentenok thanks you guys, off to bed then00:27
keithzgHrmm. New laptop at work, trying to set it up...but no response from our DHCP server (running 12.04).00:28
keithzgWireshark shows it calling out requests, and no one answers.00:30
sarnolddo the logs on the dhcp server indicate why it might be neglecting to respond? can you run wireshark on the server and see if it receives the requests?00:31
sarnoldcan you throw a hub or span port between the two systems and see the packet on the network? One common source of dhcp problems is from silly nic offloading not properly filling in the udp checksums..00:32
keithzgI've been running wireshark on my desktop, and I see the requests, but no response. Hmm. I could probably go and hook them up if there's space on the switch in the server room...it IS a laptop, after all.01:03
keithzgTo clarify, from my desktop, I see the DHCP requests from the laptop, but no ACK from the server.01:04
sarnoldhrm, the response might be sent back directed to the ethernet MAC that requested the address...01:04
keithzgYeah, fair enough.01:07
keithzgInstalling Wireshark on the server now (strange that I hadn't had to before, actually, heh).01:08
sarnoldyou might have just used tcpdump? :)01:08
keithzg...d'oh!01:11
keithzgHmm. I'm still only getting the requests from the client, but perhaps I'm only filtering for that? I must admit I'm a bit inexperienced with tcpdump.01:18
keithzgtcpdump -i br0 -vvv -s 1500 '((port 67 or port 68) and (udp[38:4] = 0x6E11BA57))'01:19
keithzgThe laptop's MAC is 08:60:6E:11:BA:5701:19
keithzgHmm, no, that's not the issue. Even if I just fire up Wireshark on the server now, and filter purely for "bootp", looking at it I can see the DHCP Discover requests from the laptop (which is now hooked up to the same switch as the DHCP server) but no Inform or ACK with the same transaction ID.01:28
sarnoldkeithzg: cripes :(01:29

rostamHI I have installed ubuntu 12.04 update 3. when system  boots , I can see the Ethernet MTU size is set to 574 bytes (ifconfig), Is this value set by defaults? thx04:11
jdstrandsarnold: not sure if you mentioned it, but I like to point people at 'sudo /usr/share/ufw/check-requirements'04:12
jdstrandsarnold: some VPSs don't give everything unfortunately04:12

sarnoldjdstrand: oh right! I forgot about ufw's check-requirements, that's way easier than trying to recall what's used :) hehe07:26
sarnoldjdstrand: thanks07:26
makarai want browse (Firefox) to a certain server, so the curl equivalent: "curl -H "Host: specialserver.website.com" website.com07:28
makarahow 2 do that?07:28
andolmakara: I assume the reason for you not simply putting specialserver.website.com in the url bar is the lack of such dns entry? How about just making an entry in your /etc/hosts file?07:43
makaraandol, correct, but there are multiple servers.07:44
makaraso hosts file is clumsy07:44
sarnoldthen set up dns?07:45
makaraI see the Modify Headers extension does the trick07:45
makaraat least I don't need to root everytime I want to switch07:45

zetheroohow can you see if the network connection on a server is being overloaded?13:07
remix_tjzetheroo: i use iptraf13:07
zetheroois there a tool which can show network bandwidth usage live?13:08
remix_tjiptraf13:08
remix_tjbut is a good idea to keep monitoring configuring mrtg13:08
zetheroook13:08
zetheroocan iptraf show a graph of the bandwidth being used?13:10
remix_tjuh, a graph no, but some infos for sure13:11

jrwrenrostam: re the 574 MTU, i've seen some DHCP servers suggest that. I usually override it. Is it your cable modem interface doing that?15:32
i3luefirei am having trouble logging in via ssh on my 12.04 server. it has worked plenty of times in the past with various forms of auth but now nothing works.15:35
jamespagezul: how many new MIR's so far for icehouse15:57
jamespage?15:57
zuljamespage:  two so far not including deps of the new MIR15:57
jamespagezul, a few on this list - http://people.canonical.com/~ubuntu-archive/component-mismatches-proposed.svg16:03
jamespageI think most of those are openstack deps right?16:03
zuljamespage:  afaik roaksoax is handling kombu but ill doublecheckdjango-compressor16:04

jamespagezul, just thinking about icehouse116:04
zetheroowe have a server with bonded ethernet's  ... I followed this to setup https://help.ubuntu.com/community/UbuntuBonding#Ethernet_Bonding_modes16:04
jamespagestart of december16:04
zuljamespage:  yeah16:04
zetheroohowever I am not sure about this line under Mode 4: Prerequisites: Ethtool support in the base drivers for retrieving the speed and duplex of each slave.16:05
zetheroohow does one find out if Ethtool is supported by the driver being used?16:05
jamespagezetheroo, query your physical interfaces using ethool16:05
jamespageif it reports information about speed and duplex - alls good16:06
jamespage:-)16:06
zetheroonever used ethtool ...16:06
zetherooinstalling it now ...16:06
zetherooethtool output ... looks good no!? http://paste.ubuntu.com/6490117/16:08
Gorash_Dag! Ik vroeg me af of iemand zin heeft om mijn settings voor postfix (vps) na te lopen. Sommige emails komen niet aan namelijk!16:10
Gorash_I mean, does someone have time to check postfix settings with me, some of mail emails are not being delivered. Sorry for dutch ;)16:10
zetheroousing iptraf it just seems like eth0 is getting 90% of the network traffic ....16:11
zetheroojamespage: ^16:11
jamespagezetheroo, yeah - that looks OK16:11
jamespagezetheroo, might be misconfiguration switch side/16:12
jamespage?16:12
zetherooeth0 will be having about 1800kbits/sec while eth1 is sitting at less than 100 ...16:12
zetherooI guess ... could be ... though on the switch side it's pretty much just LAG groups ... from what I saw anyhow ...16:13
jamespagezetheroo, can you check /proc/net/bonding/bond016:13
zetheroohttp://paste.ubuntu.com/6490144/16:14
jamespagezetheroo, that output looks OK - I would suspect switch config16:15
jamespagebut that's obviously harder to diagnose16:15

MaddethHi all, I am looking for advice on capacity planning. I am looking for some sore of software, or even a nagios plugin that can help me predict if and when my VSphere datastores are going to run out of CPU, RAM and Disk capacity. I have been writing a web front end to pull disk data from nagios based on the host and graph it, I could do the same for RAM and CPU easily enough, but I want to compare it to the clusters they are 19:37
