As i said in title, we need to erase all datas from harddisk before distroy our old servers.
Quote:
dd if=/dev/zero of=/dev/hda bs=1M
Quote:
shred -fzuv -n 100 /dev/hda
1. Which is the best practice to erase data, dd or shred?
2. How can i execute these commands in running server, do i need to re-boot the servers as RESCUE mode using bootable cd?
I already have an ubuntu backup server in my location and need this one server to be backed up remotely in another state. this other location is a helpdesk so there's a danger that they can gain access to confidential data. I'll be setting up this new server as an ftp server but need to set the ftp folder to only allow access to the backup server and me. Because its remote on the helpdesk side, they'll need some access to the file system but need to be completely blocked off from the ftp folder where all the data is at. How can I make sure I can keep them away from my data and still be able to retrieve or copy files over without permission issues between both servers?

installing Ubuntu. I want to completely delete my windows data and want to clean install Ubuntu 10.10
how can I clone my installed ubuntu to a new harddisk? with 32bit ubuntu I have used:tar cvpzf -> create a tar file on my external nas system. after that I have done a restore tar xvpfz - worked with 32 bit.
Alternative I have mounted both disks and via another linux partition I have used:
cp -rvbdR /source/* /target
both methodes worked with ubuntu 32 bit. With 64 bit ubuntu I can NOT get it to work. error message after booting the clone: /var/lib/gdm/.ICEauthoriy ..
I can see that /source/var/lib/gdm has different rights as /target - will be part of the problem.
This did not happen with the 32 bit ubuntu - but why ?

I have a 60GB hardisk, and try to install CENOS 5.5 HEL5.5 and Fedora13 on it. I partitioned the harddisk to 4 primary partitions like below:
Partition MountPoint Type
sda1 /boot ext3
sda2 VGRHEL LVM PV
sda3 VGCENT LVM PV
sda4 VGFEDORA LVM PV
I created 3 Volume Groups as you see up: VGRHEL, VGCENT, VGFEDORA; under every VG, i created 2 logical volumes ,just like below: VGRHEL=LVRHEL00(swap) + LVRHEL01(MountPoint: /) Below VG try to partition them the same as VGRHEL too. VGCENT=LVCEN00(swap) + LVCEN01(MountPoint: /) VGFEDORA=LVFEDORA00(swap) + LVFEDORA01(MountPoint: /)
I successed installed RHEL5.5 on VGRHEL, but when i try to use the same way to install CentOS 5.5, i got below error infromation: "Bootable Partitions cannot be on a logical volume" I don't why this happened, VGRHEL has logical volume too, but why i can install RHEL on it successfully.
I have a new Ultra 27 running debian and i cannot see the second internal harddisk any ideas what to do to rectify this.

For whatever reason /dev/sda3 (at /tydelik) does not mount itself (like all the other partitions) when the system reboots.
In YaST's expert partitioner it says that:
Quote:
An asterisk (*) after the mount point indicates a file system that is currently not mounted (for example, because it has the noauto option set in /etc/fstab).
Here is the /etc/fstab :
Quote:
I don't see a noauto option. Is it hiding somewhere?
Also, if I say the following then it seems that /dev/sda3 is ext2 and not ext3 (as YaST says).
Quote:
Firstly, how do I specify /dev/sda3 to be mounted by default (because I thought it would unless there is a noauto specified), and secondly, why is YaST not showing the same settings as when I say "mount" ?

I'm set in my ways and have been accustom to reformatting harddisks periodically (sector maintainance, etc.) It's worked for me as I've luckily have not had a disk crash in 25 years.My webapp is not helping me with the reformat and neither is Western Digital tech support. I've heard that it was factory formatted with something called Linux ext3. Does this make sense? Has anyone had any experience with reformatting external harddisks being used as a NAS (home use).

I have a basic question regarding how to clean up linux disk space. I use "df" to check my disk and found out usage is 100%. SO I use "du -b | sort -r -n > tmp.txt" and found out that /var/spoon/clientmqueue/ has taken the biggest disk space. I deleted the file in that directory using "rm". But after that, I run "df" again, still got 100% usage.

how can you remove all the makefiles and whatnot and basically restore the source package to its original form after you've called "./configure" or even "make" ?
for instance you changed the source code then you ran ./configure then make then make install ....etc you checked the software and it functioned as you expected it does , now you want to remove all the makefiles and all that other jizz that you don't need or want anymore in the source (obviously in order to package it for distribution)
what is the "standard" method for doing so?
