OT: Home NAS device
by Joseph L. Casale 06 Sep '08

06 Sep '08

I am looking for something that I can hack away like a NSLU2 but that thing only has one disc and worst of all its 100m interface. Anyone know of a device you can load Linux on that has maybe 2 discs like a NAS200 with a gig nic? I need a quiet device to act as a tftp-dhcp/web/dns system. I thought of just building one from a new Soekris board, or even a mini itx but hope there was something simpler/cheaper. Thanks for any reco's! jlc

Remove old kernel

I've switched from the xen kernel to regular kernel and trying to remove the xen one is giving me an error: [root@ ~]# rpm -e kernel-xen-2.6.18-92.1.10.el5 error: Failed dependencies: xen-hypervisor-abi = 3.1 is needed by (installed) xen-3.0.3-64.el5_2.1.i686 [root@ ~]# uname -r 2.6.18-92.1.10.el5 grub.conf: default=1 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-92.1.10.el5xen) root (hd0,0) kernel /xen.gz-2.6.18-92.1.10.el5 module /vmlinuz-2.6.18-92.1.10.el5xen ro root=/dev/VolGroup00/LogVol00 rhgb quiet module /initrd-2.6.18-92.1.10.el5xen.img title CentOS (2.6.18-92.1.10.el5) root (hd0,0) kernel /vmlinuz-2.6.18-92.1.10.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet initrd /initrd-2.6.18-92.1.10.el5.img [root~]# rpm -qa|grep kernel kernel-headers-2.6.18-92.1.10.el5 kernel-devel-2.6.18-92.1.10.el5 kernel-2.6.18-92.1.10.el5 kernel-xen-2.6.18-92.1.10.el5

The university department I work with recently bought some Opteron machines (two-processor 2350) HPs, and also has some recent Xeon (two-processor 5405) Dells. I ran a test on them with a Java parsing (natural language) program and found that the Xeons did 33.72 words per second, while the Opterons lagged at 20.04 words per second. These are both running the same Ubuntu version. It may not be a common or representative benchmark, but it is the kind of thing I'll be using my new machine for.

I am trying to do some new things with kickstart. I get a message that pops up "Could not allocate requested partitions" press OK to reboot. How do you go about debugging the kickstart file? How can I pop up information (in text mode) on the screen??? so I can see my values for my partitions. THanks, Jerry

Virtual email with Postfix, MySQL and Dovecot problem
by Lunix1618 05 Sep '08

05 Sep '08

Hello all, Anyone of you success to install virtual email with Postfix, MySQL and Dovecot on CentOS 5.2 ? I am running: mysql-server-5.0.45-7.el5, postfix-2.3.3-2.el5.centos.mysql_pgsql and dovecot-1.0.7-2.el5 on CentOS 5.2 box and can not make it work. All deamons (mysqld, postfix master, dovecot) are running but I can not make it deliver email to virtual user via Dovecot. The log file show that postfix is not deliver email to virtual user but it deliver to all virtual aliased address. The configuration file is working with my test on laptop that running Fedora 9 with mysql-server-5.0.51a-1.fc9.i386, postfix-2.5.1-2.fc9.i386 and dovecot-1.0.15-10.fc9.i386 The version number is not too much different so I think it is not a problem. Attached are config files that working on fedora 9 and I using it on CentOS but not work This configuration I followed the guide at http://workaround.org/articles/ispmail-etch/ I am not native English speaker so my explanation above may not clearly enough, pls raise question for me if you need further information Your advices are highly appreciates! Thank you and regards, lunix.

Centos 5 card reader automount
by Frank Cox 05 Sep '08

05 Sep '08

To this point, whenever I've plugged a storage device (flash drive, mp3 player) into a USB plug, it's magically mounted and I get an icon on my desktop. I've just got a card reader and it doesn't automount. I can mount it manually with "mount /dev/sdb1 /mnt/temp" and that works fine. I would prefer to have it automount and give me the desktop icon. Unfortunately, I don't yet know enough about the automounting mechanism to know what I need to change to make this happen. Here is the relevant portion of /var/log/messages when I plug in the card reader: Sep 4 16:31:11 bargainhunter kernel: usb 7-6: new high speed USB device using e hci_hcd and address 12 Sep 4 16:31:11 bargainhunter kernel: usb 7-6: configuration #1 chosen from 1 ch oice Sep 4 16:31:11 bargainhunter kernel: scsi11 : SCSI emulation for USB Mass Stora ge devices Sep 4 16:31:16 bargainhunter kernel: Vendor: Generic Model: USB SD Reader Rev: 1.00 Sep 4 16:31:16 bargainhunter kernel: Type: Direct-Access ANSI SCSI revision: 00 Sep 4 16:31:16 bargainhunter kernel: SCSI device sdb: 3901440 512-byte hdwr sec tors (1998 MB) Sep 4 16:31:16 bargainhunter kernel: sdb: Write Protect is off Sep 4 16:31:16 bargainhunter kernel: sdb: assuming drive cache: write through Sep 4 16:31:16 bargainhunter kernel: SCSI device sdb: 3901440 512-byte hdwr sec tors (1998 MB) Sep 4 16:31:16 bargainhunter kernel: sdb: Write Protect is off Sep 4 16:31:16 bargainhunter kernel: sdb: assuming drive cache: write through Sep 4 16:31:16 bargainhunter kernel: sdb: sdb1 Sep 4 16:31:16 bargainhunter kernel: sd 11:0:0:0: Attached scsi removable disk sdb Sep 4 16:31:16 bargainhunter kernel: sd 11:0:0:0: Attached scsi generic sg2 typ e 0 Sep 4 16:31:16 bargainhunter kernel: Vendor: Generic Model: USB CF Reader Rev: 1.01 Sep 4 16:31:16 bargainhunter kernel: Type: Direct-Access ANSI SCSI revision: 00 Sep 4 16:31:16 bargainhunter kernel: sd 11:0:0:1: Attached scsi removable disk sdc Sep 4 16:31:16 bargainhunter kernel: sd 11:0:0:1: Attached scsi generic sg3 typ e 0 Sep 4 16:31:16 bargainhunter kernel: Vendor: Generic Model: USB SM Reader Rev: 1.02 Sep 4 16:31:16 bargainhunter kernel: Type: Direct-Access ANSI SCSI revision: 00 Sep 4 16:31:16 bargainhunter kernel: sd 11:0:0:2: Attached scsi removable disk sdd Sep 4 16:31:16 bargainhunter kernel: sd 11:0:0:2: Attached scsi generic sg4 typ e 0 Sep 4 16:31:16 bargainhunter kernel: Vendor: Generic Model: USB MS Reader Rev: 1.03 Sep 4 16:31:16 bargainhunter kernel: Type: Direct-Access ANSI SCSI revision: 00 Sep 4 16:31:16 bargainhunter kernel: sd 11:0:0:3: Attached scsi removable disk sde Sep 4 16:31:16 bargainhunter kernel: sd 11:0:0:3: Attached scsi generic sg5 typ e 0 Again, it works fine if I use a mount command to mount it myself.

Configuring an Intel 3945 wireless card: partial success
by Niki Kovacs 05 Sep '08

05 Sep '08

Hi, My wife has a new ASUS laptop with an Intel 3945 wireless card. I'm running CentOS 5 on all our desktops here (at work and at home), and I'm quite happy with it. I had a partial success in configuring the wireless card. Basically I'm using [base], [updates], [extra] and [rpmforge] repos, configured with the yum-priorities plugin. Priority 10 for RPMForge, 1 for the others. From RPMForge, I installed dkms-ipw3945, the driver for my wireless card. I gave it a first go with the most basic setup, that is: static IP, no encryption. After installing the driver, the card shows up as eth1. I removed /etc/sysconfig/network-scripts/ifcfg-eth0 and edited a minimalistic ifcfg-eth1. After a restart, the interface comes up OK, and I can connect to my access point as well as ping machines on the internet. But now I'd like to install and use NetworkManager. I've read the according Wiki entry on the CentOS site. Here's what I did: 1) Added the 'NetworkManager' and 'NetworkManagerDispatcher' services (using chkconfig) 2) Removed the 'network' service (also using chkconfig) 3) Rebooted to be sure Result: 1) The NetworkManager icon shows up OK on the upper right side of my GNOME desktop. 2) When an Ethernet cable is connected to the machine, NetworkManager configures a connection OK (cable connected to router). 3) The wireless ESSID of my access point shows up OK in NetworkManager. Ethernet cables get some sort of priority in NetworkManager, so I unplugged the cable and clicked on the wireless connection. NetworkManager tries to establish a connection for about 30 seconds, but fails. ... which leaves me clueless. Any suggestions? Last detail: for the moment at least, I'm using no encryption at all on the access point. We live in a very remote place in the south French countryside, there's only hunters and wild boars around, so it's not a very friendly place for wlan-hackers :o) Niki Kovacs
