apache ssl config
by Steve Campbell 08 Dec '10

08 Dec '10

I hadn't noticed until just now that the default apache config file doesn't show a virtual host for https anymore. Does that have any significance, and do the same old config parameters apply to the new httpd when I want to set up a secure web site? Steve Campbell

copy old CF image to new CF device
by Jerry Geis 08 Dec '10

08 Dec '10

I am using an 8G CF card. (I was using dd to duplicate the card with different size cards I was advised not to). So I wrote the script below which basically: 1) runs fdisk to setup the device 2) makes the ext3 file system and the swap 3) mounts my old image "/" filesystem and the new partition 4) tar and untar the directories 5) run grub on it 6) set label for "/" After I run all the above I get: EXT3-fs error ext3_find_entry reading directory #129586 offset 0 then a couple lines later it remounts the root file system read only. What have I missed in successfully make the CF card based on the old image?

by Agnello George 08 Dec '10

08 Dec '10

HI I was just assigned a laptop with a pre install windows 7 in it. I decide to dual boot this server with cent os 5.5 , i did a "linux text " at the boot prompt as anaconda was not able to display the graphis screen ( it was barely viable ) . The installation happened perfect , but when i start x windows " startx" or init3 , i can barely see the display. I dont know where the issue lies , what module do i need to load .The display is barely visible . Thanks for all the help !! -- Regards Agnello D'souza

Problem with centos nfsroot
by me,apporc 08 Dec '10

08 Dec '10

I made a diskless node centos. the pxelinux.cfg/default file : default centos label centos kernel vmlinuz-2.6.18-194.el5 append initrd=initrd-2.6.18-194.el5.nfs.img nfsroot=10.10.10.1:/srv/centos ip=dhcp rw I can successfull*y boot-strap the system with no error.* *But when i shutdown or reboot it . It will show in the screen :* *Unmounting NFS filesystems* *INIT:no more process left in this rulevel* * * * * *and then ,it just hang.* * * *i think it is because it umounted the nfsroot filesystem and can't do the things behind. but I really have no idea about how to resolve that.* *Any help is granted. thanks.*

LVM change disk
by muhammad panji 07 Dec '10

07 Dec '10

Dear all, I have a 4,1TB Logical volume consist of four disks with size of 2TB, 1TB, 1TB, and 500GB. The LV currently full. I plan to change the 1Tb disks and 500Gb disks. I plan to remove one 1TB disk or the 500GB so that I can replace it with 2TB disk. most LVM tutorial ask to use pvmove to move phisical extent to the new disk. The problem is that I have no SATA port left so that I can't move PE to the new disk. How to migrate the data safely so that I can replace the disk? Thank you in advance regards, -- ----- Muhammad Panji

Hi All, I am attempting to install CentOS 5.5 64 bit on my new Mac Mini. I boot to the CD and when I get to selecting where I am installing from (local cd, hard disk, ftp, etc) I select Local CD and it cannot find a driver and wants me to manually specify or use a driver disk. I ave no idea what drive is in this system. Can anyone point me in the right direction? -Jason

Re: [CentOS] difference between cron and shell invocation.
by James B. Byrne 07 Dec '10

07 Dec '10

Question. In a chained cron job like this: sshfs . . . && /usr/bin/rsync . . . | /bin/mail -s . . . && . . . Is there anyway to get a failure message from the first part to be emailed or logged? Given the resolution of this problem I gather that sshfs must not have been found and therefore I would expect an error to be reported somewhere. The chained commands evidently interfered with the propagation of this error which would have immediately identified the source of the problem. Is it possible to get errors from the individual parts of such chained commands forwarded to an email address, or logged in the system log, or both? -- *** E-Mail is NOT a SECURE channel *** James B.
