Once you go double digit, and you have those many machines in one location, a local repo is the way to go. Perhaps then with one of them ( either a machine or a VM instance ) doing auto nightly updates, and running a test to make sure all is still well and sending out a small email to the admin with a OK or 'Trouble found in updates' -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh ICQ: 2522219 | Yahoo IM: z00dax | Gtalk: z00dax GnuPG Key : http://www.karan.org/publickey.asc

Theoretical Firewall Specs?
by Jason T. Slack-Moehrle 18 Jan '12

18 Jan '12

So, the more I look at various ways to lay out my infrastructure, the more I am thinking about specs for hardware. Starting with firewalling. How does one determine the specs for a firewall? What I mean is: 1. motherboard/CPU - p4? Dual-Core? Intel i3, i5, i7? 2. RAM? 4gb? 8gb? More? 32gb? 3. Obviously GB Nics! I am bring about 300gb of traffic a month right now and I expect that to increase significantly with my next offerings. Obviously one answer is to but a beefy motherboard that supports lots of RAM and add more as needed, but where does one start out? How do I know if my firewall would need more RAM? How do I know if the CPU is good enough? I still go back to my Cisco PIX days where these devices were amazing on just 256MB of RAM. We piloted a large chunk of Cornell University's Lab Of Ornithology on 2 of these, but now-a-days it seems that a PIX would not be good enough. Is it because the nature of the internet and data and attacks has changed over time? more aggressive? -Jason

If yes, I'll have to pass on this. I will post a new thread with details, its not nearly as involved as that and far simpler more practical than spacewalk. -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh ICQ: 2522219 | Yahoo IM: z00dax | Gtalk: z00dax GnuPG Key : http://www.karan.org/publickey.asc

anyone doing automatic yum updates via yum-updatesd on production servers?
by P J 18 Jan '12

18 Jan '12

I've read that it's not recommended to automatically apply updates via yum-updated on production servers, but I keep encountering servers that have this enabled. Are any of you doing automatic yum updates on production servers in CentOS 5 via yum-updatesd? Have you experienced any negative side effects? The only thing I can think of is if say a client had a custom version of PHP installed that was not properly excluded in yum and then it was over written. Unless I'm missing something else that could go horribly wrong. Any feedback is appreciated. (if this question has already been asked my apologies, searching the archive didn't find what I was looking for) Thanks, -PJ

Mic Plugged into sound card not working
by Mark LaPierre 18 Jan '12

18 Jan '12

Hey guys, I have a mic plugged into my sound card. It worked late last night but not today. When I try to select the mic using System/Preferences/Sound I'm provided with several options to choose from. On the Hardware tab I choose the Internal Audio device and set it to Analog Stereo Duplex. On the Input tab I choose Internal Audio Analog Stereo there are two Analog Microphone Inputs, 1 and 2, to choose from. Each of those inputs has Microphone 1 and 2 to choose from. When I try to record from the mic in Audacity I get a flat signal if I choose Input 1 no matter which Microphone, 1 or 2, I choose. If I choose Input 2, no matter which Microphone I choose, the wave form freezes until I return the selection to Input 1. alsamixer -c0 does not indicate any input settings being muted. In fact its indications change in response to changes in Sound Preferences and Sound Preferences indications change in response to changes in alsamixer -c0. CentOS 6.2 Advanced Linux Sound Architecture Driver Version 1.0.21 /proc/asound/cards 0 [V8237 ]: VIA8237 - VIA 8237 VIA 8237 with ALC655 at 0xd400, irq 22 /proc/asound/devices 2: : timer 3: : sequencer 4: [ 0- 1]: digital audio playback 5: [ 0- 1]: digital audio capture 6: [ 0- 0]: digital audio playback 7: [ 0- 0]: digital audio capture 8: [ 0] : control 9: [ 1- 0]: digital audio capture 10: [ 1] : control 11: [ 2- 0]: digital audio playback 12: [ 2- 0]: digital audio capture 13: [ 2] : control /proc/asound/pcm 00-00: VIA 8237 : VIA 8237 : playback 4 : capture 1 00-01: VIA 8237 : VIA 8237 : playback 1 : capture 1 01-00: USB Audio : USB Audio : capture 1 02-00: USB Audio : USB Audio : playback 1 : capture 1 I tested the mic by plugging it into my wife's XP machine. The mic works fine but the XP machine doesn't. Very frustrated. Anyone have any idea what else I can check? -- _ °v° /(_)\ ^ ^ Mark LaPierre Registerd Linux user No #267004

A little confused with video drivers
by Phil Savoie 18 Jan '12

18 Jan '12

Hello, I have an HP Pavilion g series laptop with an ATI vision A6 video chipset. I tried elrepos ati driver but found that the laptop would freeze intermittently and frequently. So I unloaded that driver and am running with nomodeset argument just to get a desktop. I went to the ATI site but am not sure what to try. Would anyone know which driver I could use that would work? Thanks in advance, Phil

Dedicated Firewall/Router
by Jason T. Slack-Moehrle 17 Jan '12

17 Jan '12

Hi All, I want to build a dedicated firewall/router as I am launching a NPO and I can host this in my garage. (Comcast offered me a 100 x 20 circuit for $99/mo with 5 statics) I used to run Untangle, but as of version 9, you are forced to use their build in protocol policies versus the firewalling I am used to (Deny All and then opening holes for specific IP's, etc). There are so many firewall distros to choose from. FireStarter, IPCOP, etc. The box I was going to use is a P4, 3GB RAM, 3 GB NICS. I could always use a beefier box also if there was really a need to for such a task. I am used to some Cisco PIX boxes and they just seem fast on hardly any specs. I had a PIX 525 that only had 256mb of RAM about 8 years ago and it was a rockstar. Thoughts, opinions, suggestions are welcome as to what to do! -Jason
