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.

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

what to do about [abrt] full crash report kernel taint?
by Thomas Burns 17 Jan '12

17 Jan '12

I have a machine with a recent install of centos (2.6.32-220.2.1.el6.x86_64 kernel). It crashed 3 times this week, and sent emails like the one below complaining about kernel taint. I've gone back to a previous kernel to see if that helps, but otherwise I don't know how to investigate this. What should I do? Here's stuff from the log and one of the emails: log:******************************** # grep -e '12 10:16' -e '10 14:46' -e '9 15:44' /var/log/messages Jan 9 15:44:11 name kernel: ------------[ cut here ]------------ Jan 9 15:44:11 name kernel: WARNING: at kernel/sched.c:5914 thread_return+0x232/0x79d() (Not tainted) Jan 9 15:44:11 name kernel: Hardware name: Precision WorkStation 490 Jan 9 15:44:11 name kernel: Modules linked in: fuse nfs lockd fscache nfs_acl auth_rpcgss autofs4 sunrpc p4_clockmod freq_table speedstep_lib ipv6 ppdev parport_pc parport sg microcode dcdbas serio_raw i2c_i801 iTCO_wdt iTCO_vendor_support tg3 snd_hda_codec_idt snd_hda_intel snd_hda_codec snd_hwdep snd_seq snd_seq_device snd_pcm snd_timer snd soundcore snd_page_alloc i5000_edac edac_core i5k_amb shpchp ext4 mbcache jbd2 sd_mod crc_t10dif sr_mod cdrom firewire_ohci firewire_core crc_itu_t ahci pata_acpi ata_generic ata_piix nouveau ttm drm_kms_helper drm i2c_algo_bit i2c_core mxm_wmi wmi video output dm_mirror dm_region_hash dm_log dm_mod [last unloaded: mperf] Jan 9 15:44:11 name kernel: Pid: 17, comm: ksoftirqd/3 Not tainted 2.6.32-220.2.1.el6.x86_64 #1 Jan 9 15:44:11 name kernel: Call Trace: Jan 9 15:44:11 name kernel: [<ffffffff81069997>] ? warn_slowpath_common+0x87/0xc0 Jan 9 15:44:11 name kernel: [<ffffffff810699ea>] ? warn_slowpath_null+0x1a/0x20 Jan 9 15:44:11 name kernel: [<ffffffff814eccc5>] ? thread_return+0x232/0x79d Jan 9 15:44:11 name kernel: [<ffffffff81071b35>] ? ksoftirqd+0xd5/0x110 Jan 9 15:44:11 name kernel: [<ffffffff81071a60>] ? ksoftirqd+0x0/0x110 Jan 9 15:44:11 name kernel: [<ffffffff810906a6>] ? kthread+0x96/0xa0 Jan 9 15:44:11 name kernel: [<ffffffff8100c14a>] ? child_rip+0xa/0x20 Jan 9 15:44:11 name kernel: [<ffffffff81090610>] ? kthread+0x0/0xa0 Jan 9 15:44:11 name kernel: [<ffffffff8100c140>] ? child_rip+0x0/0x20 Jan 9 15:44:11 name kernel: ---[ end trace ce943d42785388df ]--- Jan 9 15:44:12 name abrtd: Directory 'oops-2012-01-09-15:44:12-1647-0' creation detected Jan 9 15:44:12 name abrt-dump-oops: Reported 1 kernel oopses to Abrt Jan 9 15:44:12 name abrtd: Can't open file '/var/spool/abrt/oops-2012-01-09-15:44:12-1647-0/uid': No such file or directory Jan 9 15:44:20 name kernel: Bridge firewalling registered Jan 9 15:44:32 name abrtd: Sending an email...

bounties for exploits against CentOS?
by Bennett Haselton 17 Jan '12

17 Jan '12

With companies like Facebook and Google offering cash prizes for people who can find security holes in their products, has there ever been any consideration given to offering cash rewards to people finding security exploits in CentOS or in commonly bundled services like Apache? (Provided of course they follow "responsible disclosure" and report the exploit to the software authors and get it fixed.) Obviously the benefit would be that it would increase the chance of a white hat finding and fixing an exploit, before a black hat discovered the same one and used it to attack people's servers. Would there be any other downsides, other than the cost of paying out the prize? I've heard some objections from companies over the years who didn't want to institute a "prize program", but I thought some of those objections didn't make much sense (and indeed some of those companies ended up instituting a prize program after all, a few years later). For example, some people said, "This just encourages people to find exploits and then they might use those exploits to do harm." (The problem with this is if someone has sufficient black-hat incentives for finding an exploit -- either to do malice, or more likely to sell it on the black market -- those incentives *already* exist, so the prize program wouldn't create any additional incentive to use an exploit illegally.) Would you feel safer using CentOS if a bounty program encouraged people to report exploits to the project? Why or why not? I think I would, for the stated reason -- newly discovered exploits are more likely to get reported and fixed, than to be used in the wild. But I'd be curious why anyone might feel less safe if such a program existed. On a related question, suppose that instead of paying for generic exploits against the operating system, you as a webmaster had the option of adding your website to a directory of "bounty" sites, where you would have to put up a bond of $100 to join. Then anyone who could prove that they broke into your server (let's say the "proof" is that they read a world-readable file in the root directory) would collect the $100 prize, if they can describe exactly how they did it and what you need to fix to prevent the attack in the future. That way, if there's ever a weakness in your server, it's more likely to be found by a white hat and reported to you directly so you can fix it, before a black hat finds the same weakness. Would you sign up your webserver? I think I would, and I believe I'd be reducing the risk of a black-hat breakin as a result, but there may be counter-arguments that I'm not thinking of. Bennett

LVM question
by Jonathan Vomacka 17 Jan '12

CentOS Community, It is to my understanding that the /boot partition should never be placed on LVM and should be a physical partition on the hard drives (or on top of a RAID array). Is this an accurate statement? Also please advise if the SWAP filesystem is safe to be placed under LVM, or if this should be a hard partition / hard limit as well. I am unsure if boot issues or any filesystem issues would be caused by placing them on LVM. Please educate me if possible. Thanks in advance for the information!

CentOS Experts, I am receiving the following in /var/spool/mail/root. I cleaned out the file and then rebooted and the same errors came back.

17 Jan '12

Hi all, I have a spare USB GSM modem and it's card. I want to setup a very simple server room temperature monitor using it. Anyone has experience to share? - Program required - Script example Currently I have something like this that will send email if temp reaches something. Invoked by cron. #!/bin/bash # lm_sensors must be installed and configured first # This will check the CPU temp and send email # Changelog: # 18 Feb 2009 - created temp=$(/sbin/service lm_sensors status | /bin/grep CPU | /bin/cut -c 15-16) /bin/echo $temp #function to send mail with subject "Hot" func_mail_hot () { /bin/echo $temp | /bin/mail -s "server is hot" notification(a)arinet.org } #function to send mail with subject "Cool" func_mail_cool () { /bin/date >> /var/log/temp.log /bin/echo $temp >> /var/log/temp.log } #testing the temperature of CPU ((temp>40)) && func_mail_hot || func_mail_cool Thank you -- Fajar.
