An even lighter distro might be better but reinstalling is such a pain (it won't boot a USB stick) that I just leave it as it is. With lubuntu 14.04 being an LTS and having 5 years of updates, the laptop will probably break before I have to ever have to do a major upgrade on it again.

I've got some really weird behavior with my home file server that started early yesterday. It first presented itself with irssi being super slow (occasionally not responded) and I kept getting server disconnects. I poked around journalctl and found this:code:This morning I looked at munin and there are huge gaps in the charts, 1-2 hours which is really strange. Looking in the munin logs I see errors about connecting to the tcp port. Anyone know what's going on? I've got munin configured to use CGI for the graph generation. Edit: I've just lost network connectivity to the server (ssh/http) for 5-10 minutes, after I got back in I saw the systemd messages above. Scrolling through my buffer I see the following error appeared regularly yesterday: code:Ashex fucked around with this message at 08:26 on Apr 16, 2014 |

That's showing that nginx was stuck waiting for i/o for at least 120 seconds. My guess is that one of your hard drives is probably going south.

That doesn't make sense though as I just got this SSD. The OS/nginx are running on there. I did a lot more digging and using the sysstat tools I figured out that I was swapping pretty badly, ended up having to reboot. I need to get a PAE kernel built as I've got 8GB of memory on i686. I'm not sure why I ran out of memory as normally I'm hovering around 1.5GB. Ashex fucked around with this message at 15:00 on Apr 16, 2014 |

Is the SSD the only hard drive in that machine? Is nginx serving up any content that isn't on that hard drive? What does sar -d show for that time period as far as await and svctime?

Why is it i686 in 2014? What is the server actually running? There shouldn't be this much memory pressure on a home file server with no activity. It looks like you're potentially out of memory and swapping like mad. Or a totally unresponsive disk. Check with smartmontools?

I didn't install sysstat until this morning so I don't have historical data that would be of any use. I've got a raid 6 with six disks in it spread across the motherboard and an expansion card, nginx is only serving content on the SSD. It's i686 because the server was originally running on an atom board in 2009 and was gradually upgraded to ivy bridge over the course of a few years. I have smartmon (configured to run short/long tests) running in the background and haven't received anything aside from occasional temperature alerts.

This isn't a mission critical computer, so I have some freedom to experiment. In less than 24 hours, Ubuntu 14.04 LTS will be available, if you're sticking to the mainstream Ubuntu flavors, just hold out for a few more hours. edit: Although, it might be easier to configure/fix problems on 12.04 since it's older, and it will still be supported for a few more years. I'm having a good time with ElementaryOS. It's essentially a re-skinned version of Ubuntu 12.04LTS with a similar look/shortcuts as a Mac, and it's pretty responsive on my netbook (2009ish Atom, with 1GB of RAM). So if you're up to try something different, I recommend that. Question with firewall/snmpd. I just installed snmpd on a Debian 7 server, and I'm not able to reach that port from remote machines. I added these iptable rules on my server pre:iptables -A INPUT -p udp -m udp --dport 161 -j ACCEPT iptables -A OUTPUT -p udp -m udp --sport 161 -j ACCEPT pre:# netstat -nlpu|grep snmp udp 0 0 0.0.0.0:161 0.0.0.0:* 19173/snmpd pre:# iptables --list Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT udp -- anywhere anywhere udp dpt:snmp Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination ACCEPT udp -- anywhere anywhere udp spt:snmp edit: on a related note, are there any web based GUI that makes firewall rules easier to edit? I wouldn't complain if iptables were as easy to configure as the Windows one. I tried out Ajenti, but the firewall CP is even slower to edit than CLI. nescience fucked around with this message at 20:24 on Apr 16, 2014 |

What is the recommended program(s) for ripping an audio CD and burning an identical copy without any gaps between tracks? I've burned countless CDs with K3B, and even after removing the 2 second gap setting, I always still get a slight pause between tracks. But now I'm going to start making copies of my CD collection and I definitely do not want those gaps. Are there any settings in the ripping and/or burning process that will help make my copy perfect quality and gapless?

So I'm trying to install Ubuntu on a virtual machine while running Windows 7 on the host PC. I am using Virtual PC to run the VM. I downloaded the ISO of Ubuntu 12.04 and mount it on the virtual machine. After a few minutes I get an error saying:quote:Ubuntu 12.05 [ 17.691220] microcode: CPU0: update failed for patch_level=0x010000dc Google is not being very helpful. Anyone have any idea what might be going on or how to fix it?

microcode is like firmware for a CPU so the processor can be updated. This avoids any future F00F bugs like the original Pentium had. A virtualized CPU doesn't need microcode updates. You can probably ignore it and/or remove the microcode package(s).

nescience posted:v2c, I'm using Observium. How do I go about testing what you've mentioned? First, you'll need to have the command-line net-snmp tools installed, both on the system you have trouble monitoring, and on the system that is running your monitoring package. Depending on your Linux distribution, they may or may not be in the same package as the snmpd daemon. For example, on Debian, they come with the "snmp" package; on RHEL6, the package name is "net-snmp-utils". Then, you'll need to know the configured SNMP community name. If you have configured multiple community names, one with read access only is fine. If you haven't configured any community name, try "public". So, assuming that your community name is "public", run this on the host that runs the snmpd you wish to monitor, to verify that snmpd works: code:If you get "Timeout: No Response from 127.0.0.1", make sure your snmpd daemon is actually running and your community name is correct. Then, run the same command on your Observium host, replacing 127.0.0.1 with the IP address with the real IP of the system you wish to monitor. Unless you've done something clever with the access control rules of snmpd, you should get pretty much the same multi-line response as when running the command locally. If snmpwalk works on localhost but not on the Observium host, something is blocking the SNMP packets between the hosts. Perhaps the Observium host too needs to have its iptables firewall modified to allow SNMP?

Posting this from chrome in Ubuntu 12.04 on my laptop. Setup has a few kinks due to lovely internet connections and a proprietary wifi driver, but once I got the computer plugged into a LAN, it was trivial. Still going to upgrade my memory because things are a tiny bit laggy, but overall a HUGE improvement over XP. If I do decide to eventually upgrade to 14.04, is it like installing a new version of windows, or am I able to just install it over 12.04 and have all my apps and whatnot come along for the ride? I'm assuming it's more like upgrading the OS on a mac than upgrading the OS on windows. Not surprisingly, Ubuntu reminds me a lot of the version of OSX that I was using until a couple years ago. And I'd forgotten just how awesome it is to be able to go into terminal to diagnose issues and whatnot.

That's an old version of the stock GNOME 3 theme. The borders around the panel are gone in newer versions, making the panel melt into the monitor / laptop bezel.

The only thing that changed is that we removed the tiny white border below the panel. It might take a bit of getting used to, but I think it looks better without it.

I'm doing some funky poo poo again, and can't figure out how to get what I want. I'm connecting to ISCSI targets using open-iscsi, and I want to be able to make sure the device nodes are created with specific names. As things are right now, it just uses the first free letter (/dev/sda, /dev/sdb, etc). Open-iscsi does not seem to have any option for specifying the device name when connecting. For example, I want to connect to some target 'asdf' at 10.1.0.1 and place the device node at /dev/sdb. Here's dumb poo poo I've done so far: Idea 1: Create a symlink from /dev/sde to /dev/disk/by-path/ip-10.1.0.1:3260-iscsi-iqn.asdf.org:blah-lun-1 (which is itself a symlink to /dev/sda) Problems: If you partition the device, there won't be any symlinks to the partitions. If I later connect to another device (after /dev/sda has been created and /dev/sdb links to the /dev/disk/by-path/...), open-iscsi (or the scsi kernel module?) tries to create /dev/sdb, but can't. The connection succeeds but no device node is created. Idea 2: When connecting to a new target, get rid of the nodes it creates automatically, and create my own device nodes with the correct major/minors Problems: This kinda works, except that when I fdisk /dev/sdb (Which I have created with major 8 and minor 0) and create a new partition, I end up with a /dev/sda1 instead of /dev/sdb1. Is this something I can solve with udev rules somehow? I'm starting to get lost.
