Re: apt is killing my machine
I run Sarge on an openz vps with strictly allocated 64MB RAM. apt-get upgrade will fall over with dpkg malloc errors. So instead I have a script which effectively does: apt-get update apt-get upgrade --download-only -y dpkg -Ri /var/cache/apt/archives/ apt-get clean So far this has always worked, whereas plain 'apt-get upgrade' will not. Packages can be installed using a similar method. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

wlan0 fails to obtain dhcp lease at startup
Hi, I have a problem with wlan0 failing to get a dhcp lease at startup. At startup, the following messages are issued: Sun Aug 10 20:20:07 2008: DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 3 Sun Aug 10 20:20:10 2008: DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 8 Sun Aug 10 20:20:18 2008: DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 15 Sun Aug 10 20:20:33 2008: DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 10 Sun Aug 10 20:20:43 2008: DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 10 Sun Aug 10 20:20:53 2008: DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 15 Sun Aug 10 20:21:08 2008: No DHCPOFFERS received. Sun Aug 10 20:21:08 2008: No working leases in persistent database - sleeping. *After* startup however, 'ifdown wlan0; ifup wlan0' succeeds with a lease at the first attempt. Similarly 'dhclient wlan0' will obtain a lease after startup. The machine is a Dell Latitude D630 laptop. I'm running Etch since the machine was set up, and reecently did an apt-get upgrade after a prolonged period offline. I am reasonably certain that dhcp on wlan0 at startup did work when I originally set the machine up and suggest that something has changed to cause this problem. The server running dhcpd logs no attempt to obtain a lease from this machine at the time of boot. Below is paste of dmesg, bootlog, lspci, and /etc/network/interfaces. Any insight to the cause of this problem would be much appreciated!

Sound recorder records only silence
Hi, I hope someone can help with this problem... I'm trying to get the microphone input working (actually for use with Skype). I'm using audacity, arecord, and the gnome sound recorder to test the mic input and whichever app I use it records only silence. In the Gnome volume control: Playback tab - Microphone slider is set to 100, and not muted Capture tab - Both sliders set to 100 and not muted Switches tab - Microphone Capture is ticked Options tab - Mic Select set to Mic1, Mono select set to Mic Blowing or touching the microphone can be clearly heard on the PC speakers, holding the mic next to the speakers causes a feedback 'howl', speech is distorted. However, any recording records just silence: ~# arecord -d 10 test.wav Recording WAVE 'test.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono ~# hd test.wav 52 49 46 46 a4 38 01 00 57 41 56 45 66 6d 74 20 |RIFF.8..WAVEfmt | 0010 10 00 00 00 01 00 01 00 40 1f 00 00 40 1f 00 00 |[EMAIL PROTECTED]@...| 0020 01 00 08 00 64 61 74 61 80 38 01 00 80 80 80 80 |data.8..| 0030 80 80 80 80 80 80 80 80 80 80 80 80 80 80 80 80 || * 000138a0 80 80 80 80 80 80 80 80 80 80 80 80 || 000138ac ~# arecord -l List of CAPTURE Hardware Devices card 0: CS46xx [Sound Fusion CS46xx], device 0: CS46xx [CS46xx] Subdevices: 1/1 Subdevice #0: subdevice #0 ~# amixer info Card default 'CS46xx'/'Sound Fusion CS46xx at 0xfcffe000/0xfce0, irq 193' Mixer name: 'Cirrus Logic CS4297A rev 4' Components: 'AC97a:43525914' Controls : 45 Simple ctrls : 26 ~# man amixer Reformatting amixer(1), please wait... ~# amixer scontents Simple mixer control 'Master',0 Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left - Front Right Limits: Playback 0 - 63 Mono: Front Left: Playback 48 [76%] [on] Front Right: Playback 48 [76%] [on] Simple mixer control 'Master Mono',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined Playback channels: Mono Limits: Playback 0 - 31 Mono: Playback 24 [77%] [on] Simple mixer control 'Headphone',0 Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 24 [77%] [on] Front Right: Playback 24 [77%] [on] Simple mixer control '3D Control - Center',0 Capabilities: volume volume-joined Playback channels: Mono Capture channels: Mono Limits: 0 - 15 Mono: 0 [0%] Simple mixer control '3D Control - Depth',0 Capabilities: volume volume-joined Playback channels: Mono Capture channels: Mono Limits: 0 - 15 Mono: 0 [0%] Simple mixer control '3D Control - Switch',0 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [off] Simple mixer control 'PCM',0 Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 28 [90%] [on] Front Right: Playback 28 [90%] [on] Simple mixer control 'Line',0 Capabilities: pvolume pswitch pswitch-joined cswitch cswitch-exclusive Capture exclusive group: 0 Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: Playback 0 - 31 Front Left: Playback 0 [0%] [off] Capture [off] Front Right: Playback 0 [0%] [off] Capture [off] Simple mixer control 'CD',0 Capabilities: pvolume pswitch pswitch-joined cswitch cswitch-exclusive Capture exclusive group: 0 Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: Playback 0 - 31 Front Left: Playback 25 [81%] [on] Capture [off] Front Right: Playback 25 [81%] [on] Capture [off] Simple mixer control 'Mic',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined cswitch cswitch-exclusive Capture exclusive group: 0 Playback channels: Mono Capture channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Playback 31 [100%] [on] Front Left: Capture [on] Front Right: Capture [on] Simple mixer control 'Mic Boost (+20dB)',0 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [off] Simple mixer control 'Mic Select',0 Capabilities: enum Items: 'Mic1' 'Mic2' Item0: 'Mic1' Simple mixer control 'Video',0 Capabilities: pvolume pswitch pswitch-joined cswitch cswitch-exclusive Capture exclusive group: 0 Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: Playback 0 - 31 Front Left: Playback 0 [0%] [off] Capture [off] Front Right: Playback 0 [0%] [off] Capture [off] Simple mixer control 'Phone',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined cswitch cswitch-exclusive Capture exclusive group: 0 Playback channels: Mono Capture channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Playback 0 [0%] [off] Front Left: Capture [off] Front Right: Captur
Re: Sound recorder records only silence
> Try running alsaconf as root and check that you are configuring the right > sound > card (there may be sound built into the motherboard as well as a PCI card). Hi, thanks for the suggestions. I did already run alsaconf as root prior to the transcript pasted in my last post. There is no PCI sound card, only the onboard sound which I am using. What is bizarre is that I have this same problem on two very different machines - a Dell Precision 420 desktop, and an IBM Thinkpad T21 laptop. Which leads to the suspicion either of a bug in 'etch', or more likely something that I have done wrong. It certainly looks like a bug from where I'm sitting, even if it works for everyone else! ;-/ Any other suggestions much appreciated... Cheers, -bernie.

Curious file-permissions problem
Hi, I wonder if someone can throw some light on this file-permissions issue please? It came to light as rsync complained: rsync: failed to set times on "/var/www/mirror/foo/.": Operation not permitted (1) An strace revealed the failure is effectively a result of: cd /var/www/mirror/foo; touch -m . The directory is group writable and with ownership root.staff, rysnc is running as a user who is a member of group staff. Now maybe there's a better way to manage the file permissions for mirroring with rysnc, and maybe someone will comment on that as a side discussion, but mainly I'm curious why the directory mtime cannot be set in this way. Some testing at the command line indeed confirms that it's not possible to 'touch -m' or 'touch -a' a directory without direct ownership, but plain 'touch' will succeed as long as group permissions include write access. My suspicion is this is a security feature, but I fail to see it because the same as 'touch -m' can be achieved by simply creating and then deleting a dummy file within the directory, as demonstrated below. This is also at http://pastebin.com/m6896ed8a for those who might prefer to view it there. Total respect due to any guru who can explain this... I've asked around already and received no satisfactory explanation! ~$ ls -la /tmp/foo total 8 drwxrwxr-x 4 root staff 1024 2007-11-26 22:53 . drwxrwxrwt 17 root root 5120 2007-11-27 00:08 .. drwxrwxr-x 2 gm gm1024 2007-11-27 00:40 bar drwxrwxr-x 2 root staff 1024 2007-11-27 00:40 baz ~$ groups gm dialout cdrom floppy audio src video plugdev staff users powerdev ssh-login ~$ touch /tmp/foo/bar ~$ stat /tmp/foo/bar File: `/tmp/foo/bar' Size: 1024Blocks: 2 IO Block: 4096 directory Device: 308h/776d Inode: 132531 Links: 2 Access: (0775/drwxrwxr-x) Uid: ( 1000/ gm) Gid: ( 1000/ gm) Access: 2007-11-27 00:40:36.0 + Modify: 2007-11-27 00:40:36.0 + Change: 2007-11-27 00:40:36.0 + ~$ touch -a /tmp/foo/bar ~$ touch -m /tmp/foo/bar ~$ stat /tmp/foo/bar File: `/tmp/foo/bar' Size: 1024Blocks: 2 IO Block: 4096 directory Device: 308h/776d Inode: 132531 Links: 2 Access: (0775/drwxrwxr-x) Uid: ( 1000/ gm) Gid: ( 1000/ gm) Access: 2007-11-27 00:40:50.0 + Modify: 2007-11-27 00:40:56.0 + Change: 2007-11-27 00:40:56.0 + ~$ touch /tmp/foo/baz ~$ stat /tmp/foo/baz File: `/tmp/foo/baz' Size: 1024Blocks: 2 IO Block: 4096 directory Device: 308h/776d Inode: 132530 Links: 2 Access: (0775/drwxrwxr-x) Uid: (0/root) Gid: ( 50/ staff) Access: 2007-11-27 00:41:08.0 + Modify: 2007-11-27 00:41:08.0 + Change: 2007-11-27 00:41:08.0 + ~$ touch -a /tmp/foo/baz touch: setting times of `/tmp/foo/baz': Operation not permitted ~$ touch -m /tmp/foo/baz touch: setting times of `/tmp/foo/baz': Operation not permitted ~$ stat /tmp/foo/baz File: `/tmp/foo/baz' Size: 1024Blocks: 2 IO Block: 4096 directory Device: 308h/776d Inode: 132530 Links: 2 Access: (0775/drwxrwxr-x) Uid: (0/root) Gid: ( 50/ staff) Access: 2007-11-27 00:41:08.0 + Modify: 2007-11-27 00:41:08.0 + Change: 2007-11-27 00:41:08.0 + ~$ touch /tmp/foo/baz/file; rm /tmp/foo/baz/file ~$ stat /tmp/foo/baz File: `/tmp/foo/baz' Size: 1024Blocks: 2 IO Block: 4096 directory Device: 308h/776d Inode: 132530 Links: 2 Access: (0775/drwxrwxr-x) Uid: (0/root) Gid: ( 50/ staff) Access: 2007-11-27 00:41:08.0 + Modify: 2007-11-27 00:41:37.0 + Change: 2007-11-27 00:41:37.0 + ~$ ~$ ~$ -grummund -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
