ALSA - mic trouble
by Eric Stein 03 Sep '06

03 Sep '06

Hi, When I first set up my Ubuntu machine, everything worked fine. But for the last few months (I don't remember exactly how long), my mic has refused to work. Nothing I use can pick up any signal from it. I've tried all the mixers (alsamixer, kmix, the built in GNOME mixer), and none of them show the mic as muted. Is there a way to reset ALSA's volumes and other mixer settings to defaults? I can't seem to find information about this online, and this lack of a fully working sound system has me on the end of my rope. Info: Ubuntu Breezy 5.10 Linux pippin 2.6.12-10-386 #1 Tue Jul 18 22:08:27 UTC 2006 i686 GNU/Linux I'm prepared to spend a good deal of time on this, but I don't know what I need to do. If you need more information, let me know how to get it and I'll be happy to share it. Eric

iptables use of --mac-source
by Andy Stewart 02 Sep '06

02 Sep '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI everybody, I'm playing with my firewall rules, trying to setup a rule that will recognize my laptop's mac address on an incoming connection. I tried this: iptables -I INPUT -m mac --mac-source uu:vv:ww:xx:yy:zz -j LOG - --log-prefix "Laptop Detected: " That worked fine. I saw the appropriate log entry when my laptop ping'd the firewall. The log entry showed the expected mac address of my laptop. At that time, my laptop was plugged into my home network, which is connected to the "internal" interface of my firewall. I then setup iptables to log all incoming packets from the firewall's external interface, and I noticed that in the log all incoming mac source addresses are the same. I didn't expect this. The address is 00:0b:bf:xx:xx:xx, which I think is a piece of Cisco hardware, and I don't have any Cisco hardware at home. Is this some hardware from my ISP ? I'm guessing somebody is rewriting the packets to replace the source mac address, but clearly my knowledge of this is lacking, and thus I'm confused. Any helpers?

My memory leak problem from last week.

I have moved from mozilla mail and mozilla browser to thunderbird mail and firefox browser. The memory leak problem seems to have either gone away completely or greatly been reduced. Interesting... thanks for the suggestions and help. Ken Jones

My memory leak problem.
by ken jones 24 Aug '06

Everyone: It is hard to believe that X is the problem. It came with Fedora 4 and no one else seems to be reporting it as a bug. I have another Fedora 4 machine that does not display this swap space problem. Karl's idea of looking carefully at my drivers is a good one. This machine has more than one special driver. It is late now. I am tired. I shall pursue this track tomorrow or Friday. If anyone else is interested in the cut and paste of ps auxw lspci uname -a lsmod vmstat dmesg tell me. I will send you a copy. Thank you all:-) Ken Jones Thank you.

Keep watching this process if it's memory size grows then there may be a memory leak eating up your memory.. I'm not a fedora expert, are there any X updates? have you run yum or updated your system? What version of X are they using? perhaps send your /var/log/xorg.0.log [root@kjones-fedora kjones]# lspci 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R300 NE [Radeon 9500 Pro] 01:00.1 Display controller: ATI Technologies Inc Radeon R300 [Radeon 9500 Pro] (Secondary) I see you have an ATI graphics card. Do you know what video driver you are using? perhaps there is a problem there.

I have setup a few servers with 1TB, 1.5TB and 2TB doing NFS, mainly for video streaming and at most 15-20 NFS clients. Using kernel 2.6.15.7 for a while now with no performance complaints. I have seen 15 NFS clients streaming DVD quality mpeg2 video (9mbps) work nicely. Getting over 2TB, tho starts to be a lot of disks and there are heat problems, also problems finding enough drive bays. -- Karl Hiramoto http://karl.hiramoto.org/

storrage suggestion
by Karl Hiramoto 22 Aug '06

22 Aug '06

Anyone have suggestions? i need: * >= 5TB disk space * iSCSI, ATA over Ethernet, or NFS mountable to linux >= 2.6.15 *RAID (must survive single disk failure) and must know when a failure happened. * $$/TB is important. * Must be able to sustain minimum 10MB/s disk read on Gbit network. normally these will be big multimedia files. Yes, i know i can buy a linux PC, and slap in 11 or more 500 GB disks and do this RAID5. Something off the shelf, and easy to service would be nice. -- Karl Hiramoto http://karl.hiramoto.org/

Re: [Wlug] router/printing problems
by Bill Mills-Curran 22 Aug '06

Thanks for all the suggestions from the group. There were several requests for a more clear description of the setup. Here it is: Verizon FIOS DSL <=> Actiontek router (192.168.1.1) <=> LinkSys router (192.168.1.20 <=> 192.168.2.1) Linux box (with samba printer): 192.168.1.14 windows box (needing to print): 192.168.2.200 The fix: 1. Enable printing from 192.168.2.x in the samba setup. (I'm not sure that helped, because the LinkSys router was set up as a gateway, thus the print request showed up from 192.168.1.20.) 2. Set up a route to the 192.168.2.x network on my linux box. 3. Lots of mucking around with the LinkSys. I also opened it up to all outside access. I also set "dynamic routing". 4. Whacked at the windows box quite a bit. It finally (magically?) started working. Unresolved questions: 1. What did I do to make it work? 2. Why do I need to keep the LinkSys set with the "gateway" rather than the "router" setting? If I set "router", then I can access between the 2 networks nicely, but the 192.168.2.x will not route to the internet. Maybe I needed a static route? It would be nice to understand what was the key. I'd also like to understand how to set the LinkSys as a router rather than a gateway, but at least it works and my wife is no longer reminding me how much linux messes things up. :-) Thanks, Bill

router/printing problems
by Bill Mills-Curran 21 Aug '06

21 Aug '06

I have a home network with 2 routers. My 192.168.2.x network has a couple of windows boxes (some wireless) behind a linkSys router. This network feeds to my 192.168.1.x network which connects to the internet through a second router. My linux box (samba print server) is on the 192.168.1.x network and has a static IP. I just moved to this setup when I got Verizon FIOS. (Their wireless router has poor range.) Problem. Since moving, I can't print to the samba-served printer from the windows boxes. I have modified samba to accept connections from the 192.168.2.x machines. Here's my samba log for the machine that tries to print.
