| brunost | hi! I'm working on setting up a little home server (my first server I may add) and I am trying to figure out what would be the best way to deal with a drive to run the OS on | 00:32 |
|---|---|---|
| gdeeble | You only have 1 drive? | 00:32 |
| gdeeble | or multiple? | 00:32 |
| brunost | gdeeble: I'll have a raidz of 4 drives for storage | 00:33 |
| brunost | I am trying to figure out what solition to go for for storing the OS | 00:33 |
| brunost | optimally a solution like freenas where it loads an image from a pendrive to ram would be the best | 00:33 |
| brunost | but I don't really have enough knowledge about this myself to figure out if this is a clever solution | 00:34 |
| gdeeble | brunost: See I have my os on 1 drive then mounted my raid to a mount point. | 00:34 |
| ironm | duli, I was thinking also about such concepts (just using xen ... but I didn't get the xen live image working as wanted wanted and had to stop due to missing time resources) | 00:35 |
| ironm | <duli> ironm: i'd like to use ubuntu on the flash drive as a server solely for manage virtual machines. The real storage will be built on 3 HDs using ZFS | 00:35 |
| ironm | but ubuntu-server is definitively the best base for kvm hosts | 00:35 |
| brunost | ofc I'll keep the OS on a separate drive, just not sure if I should try out loading from usb to ram or use a 2.5" drive of some sort | 00:35 |
| duli | ironm: i think so algo. | 00:35 |
| duli | ironm: but I've given up the idea of using ubuntu-server on a usb stick | 00:36 |
| duli | would require a lot of tweaks to reduce disk writes | 00:36 |
| gdeeble | brunost: depends on your needs. I have a little hard drive running my os, but USB solutions are def. nice as long as everything wants to play ball. | 00:36 |
| duli | I'll go with a simple notebook hd (5400 rpm) to t install the sustem | 00:36 |
| brunost | gdeeble: thats the thing, will I get it to play nicely | 00:37 |
| ironm | duli, I gave such ideas too ;) ... I run ubuntu-servers as kvm hosts on raid5 or raid6 (with 4 or 8 drives) .. and use additional raid5 or raid6 as storage for VMs | 00:37 |
| ironm | duli, well .. when you run in live you don't need really to care if your KVM host have enough RAM (ECC) | 00:38 |
| ironm | gdeeble, I use own debian live images (booting from a USB stick) for my daily work .. it works great :) | 00:39 |
| duli | ironm: sure, but my concern would be the usb key falling appart in a short period of time | 00:39 |
| duli | ironm: since you mentioned kvm | 00:39 |
| ironm | duli, yes .. that can happen | 00:39 |
| gdeeble | brunost: I never had success myself but I am still a novice at this. I ended up using Zentyal which uses ubuntu with a web management face. | 00:39 |
| ironm | gdeeble, eg. ... http://rsync.it-infrastrukturen.org/postgresql/live-wheezy-amd64-awesome-public-databases-20121024e.iso | 00:39 |
| duli | ironm: is it possible to open a vm machine remotely, using the virt-manager? | 00:40 |
| ironm | duli, yes | 00:40 |
| ironm | duli, like: ironm@wheezy:~$ virt-manager -c qemu+ssh://192.168.1.75/system | 00:40 |
| duli | ironm: ah, that's so great! | 00:40 |
| duli | ironm: so I can perfom the os install on the vm remotely, right? | 00:41 |
| gdeeble | ironm: I always ran into something but I think my problem was lack of patience and knowledge when I was trying. | 00:41 |
| ironm | duli, 192.168.1.75 is a ubuntu-server KVM host (HP DL385g7 ,,, with 32 or 64GB ECC RAM and 2 pieces of P410 RAID controller with 1GB cache each ... and 16 SCSI drives) | 00:42 |
| gdeeble | but that was a few years ago. | 00:42 |
| ironm | duli, you have to put .iso images for the installation inside /var/lib/libvirt/images/ an the KVM host, but the installation of VMs happen mostly from remote client (with the command like above) | 00:43 |
| duli | ironm: ah, ok, that was my doubt | 00:43 |
| duli | well, fair enough | 00:43 |
| duli | seems nice | 00:43 |
| ironm | virt-manager doesn't offer you the possbility to use local .iso images on the virt-manager client for installation on the KVM host | 00:44 |
| ironm | duli, you need "virtual machine host" tasksel option of ubuntu-server to install the KVM host. You need also the ssh-server tasksel option for virt-manager (remote) | 00:47 |
| duli | ironm: ok, that's totally fine. I could always do a scp to the kvm host | 00:47 |
| duli | ironm: ok,. I just complet4ed the install and selected those to options | 00:47 |
| duli | ironm: I already have ssh access to it | 00:47 |
| duli | ironm: do you recommend ant specific tutorial on kvm/ubuntu? | 00:48 |
| ironm | gdeeble, now a day linux live images are very comfortable | 00:49 |
| ironm | duli, eg. this one : Red_Hat_Enterprise_Linux-6-Virtualization_Host_Configuration_and_Guest_Installation_Guide-en-US.pdf | 00:50 |
| ironm | I can't find the link | 00:50 |
| duli | ironm: no prob., I'll go through the redhat manuals | 00:50 |
| duli | tks a lot | 00:51 |
| ironm | duli, give me few minutes . I have some links also for ubuntu | 00:51 |
| duli | ok | 00:51 |
| ironm | duli, may I pc you? (query) | 00:52 |
| duli | sure | 00:52 |

| LeChacal | hello, i am trying to setup the 2nd nic in my server for a local connection to another machine through a swtich using static IP and it isn't working, this is my interface file http://paste.ubuntu.com/1349628/ am I missing something in my interface file or something else i needed to do. If I reboot the interface doesn't automatically come up and if I bring it up manual it doesn't ever list as having the address set in the interface file. | 02:51 |
| qman__ | two things | 02:54 |
| qman__ | you can't have more than one default gateway without a lot of extra config, or it will just choose at random which interface to send traffic out of | 02:55 |
| qman__ | and you're missing auto eth1 | 02:55 |
| qman__ | and you can't have IPs from the same subnet on different interfaces | 02:55 |
| qman__ | I lied, three things | 02:55 |
| LeChacal | ok so do i just not set a gateway on the 2nd nic then? And I have differnt subnets DHCP gives out 192.168.1.x and the static is 192.168.0.141. | 02:56 |
| qman__ | yes | 02:56 |
| qman__ | you only set a gateway on your internet-facing side | 02:56 |
| qman__ | if you have more than one internet-facing address, you have to do some extra stuff to get it to either prefer one or load balance | 02:57 |
| qman__ | dhcp sets a gateway automatically, so just remove the manual one | 02:57 |
| LeChacal | ok i have made the changes and rebooting, ill see if that was all my problems shortly | 02:59 |
| LeChacal | qman_ thank you that seems to fix my problem | 03:01 |

| bananapie | Is there a command in ubuntu to which I can pipe an email and an IP address and it would send an abuse report to the abuse email for the given IP ? | 14:12 |
| bananapie | I got hits attacks from 200 different IPs in a 24 hour period, I could never work on this list by hand. | 14:14 |
| patdk-lap | bananapie, only 200? | 14:20 |
| bananapie | that's if I count each IP only once. | 14:20 |

| NomadJim | anyone running an ubuntu webserver that can share some anecdotal evidence of how often they have to patch their server? | 21:42 |
| ikonia | you patch your servers when ubuntu provides package updates | 21:46 |
| ikonia | it's that simple | 21:46 |
| DaveR | iirc there is a setting to have your sever automatically deploy security related patches | 21:47 |
| ikonia | yes, but that's not wise | 21:49 |
| ikonia | as you don't want to blindly patch unless you have a test system first | 21:49 |
| DaveR | that's fair | 21:50 |
| greppy | NomadJim: I use apticron to get emailed notifications of pending updates. | 21:56 |
| NomadJim | ikonia: i'm looking for number of times/year or some other kind of statistic | 21:57 |
| ikonia | NomadJim: it changes from release to release and version to version, you can't guess how many bugs or security alerts will be found | 21:58 |
| NomadJim | because it's going to be different based on packages, i'd like to focus on people with web servers | 21:58 |
| ikonia | NomadJim: it will differ for different people depending on what packages they are using | 21:58 |
| NomadJim | yup | 21:59 |
| NomadJim | maybe i'll compile something if I can't find it on google | 22:03 |
| DaveR | NomadJim, I make a point on my box to check weekly. Having said that though, I will say this: my box is for personal use and therfore if it breaks/gets owned its not that big of a deal. | 22:14 |
| DaveR | ie: I'm not saying that weekly updates are the best or that it's how you should do it | 22:14 |
| greppy | I still like apticron as a way to get notification of new package updates. | 22:15 |
| NomadJim | yeah i think automatic notification like greppy said would be best when i'm actively administering a production server | 22:15 |
| greppy | that way you don't have to remember to login and check, if there is an update, you get an email. | 22:15 |
| NomadJim | i have a whole bunch of personal use servers | 22:16 |
| NomadJim | but i usually outsource it to a managed provider if it gets important | 22:16 |
| NomadJim | so I am not very good at best practices | 22:17 |
| NomadJim | greppy: might be kind of cool if someone combined apticron + uptime monitoring | 22:25 |
| NomadJim | as a service for lazy people | 22:26 |
| ikonia | or you could just not be lazy | 22:26 |
| ikonia | and run the server properly | 22:26 |
| NomadJim | ikonia: i'm talking about a business idea as opposed to personal administration | 22:27 |
| ikonia | doesn't seem a good idea to me personally | 22:27 |
| NomadJim | i bet someone is already doing it though | 22:27 |
| NomadJim | what's the downside of having apticron in addition to the normal uptime monitoring most services provide | 22:27 |
| ikonia | that's not what it was meant to do | 22:28 |
| ikonia | so you're just adding a pointless function to it | 22:28 |
| ikonia | there are tools for monitoring - this isn't one of them, so adding one random monitoring measure to it doesn't seem good | 22:28 |
| NomadJim | I'm talking about uptime monitoring services like https://www.pingdom.com/ | 22:29 |
| ikonia | yeah, I'm saying I think it's a bad idea | 22:29 |
| NomadJim | I think it would be valuable if they added apticron notifications as well to their offering | 22:29 |
| ikonia | that's not what the tool was meant for | 22:29 |
| NomadJim | notifying of updates isn't what apticron is for? | 22:29 |
| ikonia | no, monitoring | 22:29 |
| ikonia | there are already monitoring plugins for most proper monitoring solutions | 22:30 |
| ikonia | sorry, I just think it's a bad/pointless idea | 22:30 |
| NomadJim | apticron doesn't do the monitoring it's an addition | 22:30 |
| ikonia | what ? | 22:30 |
| NomadJim | i'm not quite sure what you're arguing | 22:30 |
| ikonia | that uptime monitoring included as part of aptcron is a bad idea | 22:31 |
| ikonia | which is what you stated | 22:31 |
| NomadJim | i'm saying uptime monitors like https://www.pingdom.com/ | 22:31 |
| NomadJim | could add apticron | 22:31 |
| ikonia | why ? | 22:31 |
| greppy | NomadJim: xymon can monitor apt status, including apticron. | 22:32 |
| ikonia | there are already solutions/plugins for proper monitoring solutions | 22:32 |
| ikonia | tools like pingdom are not monitoring solutions | 22:32 |
| NomadJim | greppy: that's cool. currently trying to learn zabbix, don't know if that's equivalent ot xymon | 22:32 |
| greppy | NomadJim: xymon used to be hobbit which used to be big brother. I find that I prefer it to most other monitoring solutions. | 22:33 |
| NomadJim | http://en.wikipedia.org/wiki/Comparison_of_network_monitoring_systems | 22:36 |
| NomadJim | looks like they are pretty similar | 22:36 |
| NomadJim | at least in terms of features | 22:36 |
