Re: [CentOS] Oracle Linux 8 - short experiment with install and basic setup of Mate Desktop

I'll try to answer best to my knowledge. Is it necessary to create an Oracle account to do anything with Oracle Linux that can't be done without creating an account? No Account needed. In other words, does Oracle Linux demand that you log into Oracle to complete an installation, update that installation, install software from their epel-equivalent, or do any other of the regular sysadmin activities that one would expect to be doing? No. If I start installing Oracle Linux on my machines or my client's machines, what benefit do I get by signing up for an Oracle account that I don't have if I don't sign up for one? I have an oracle account but never used it for/with Oracle linux. Does Oracle Linux have a free support and discussion mailing list similar to this one?

Re: [CentOS] Is Oracle a real alternative to Centos?
Am 08.12.20 um 18:54 schrieb Frank Cox: Is Oracle a real alternative to Centos? I'm asking because genuinely don't know; I've never paid any attention to Oracle's Linux offering before now. But today I've seen a couple of the folks here mention Oracle Linux and I see that Oracle even offers a script to convert Centos 7 to Oracle. Nothing about Centos 8 in that script, though. https://linux.oracle.com/switch/centos/ That page seems to say that Oracle Linux is everything that Centos was prior to today's announcement. But someone else here just said that the first thing Oracle Linux does is to sign you up for an Oracle account. So, for people who know a lot more about these things than I do, what's the downside of using Oracle Linux versus Centos? I assume that things like epel/rpmfusion/etc will work just as they do under Centos since it's supposed to be bit-for-bit compatible like Centos was. What does the "sign up with Oracle" stuff actually do, and can you cancel, avoid, or strip it out if you don't want it?

[CentOS] C6: kickstart problems with additional repo
Hi, I'm kickstarting a vm in ESXi 5.1. ks.cfg is on floppy, install media is ISO file. This works great as long as I don't add an additional repo, in our case it is vmware tools on one of our webservers. If I add the repo line, anaconda asks then for the used network card and indeed, switching to console the interfaces are still unconfigured. Chosing eth0 in gui continues the installation! This is the relevant part of ks.cfg install cdrom lang de_DE.UTF-8 keyboard de-latin1 skipx network --onboot yes --device eth0 --bootproto static --ip=192.168.200.28 --netmask=255.255.255.0 --gateway=192.168.200.1 --nameserver=192.168.200.9 --noipv6 network --onboot no --device eth1 --bootproto static --noipv6 network --onboot no --device eth2 --bootproto static --noipv6 repo --name=vmware51 --baseurl=http://xxx/repo/vmware/5.1/rhel6Server-x86_64/ I'm beginning to think the problem is, my install media is ISO and I have an additional http repo which is not available in this stage... Is there any workaround? Thx Rainer ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

No, does not help. GUI still says it needs an active network connection. :( Are you able to establish communication with the web server that is hosting vmware tools I do not have the same environment as you, therefore my ks.cfg, installation media and the repo is on the same FTP server. I'm only being asked to configure the network, if I'm not able to establish communication with the FTP server, verify that the appropriate access is on file/s that the server need to connect to. Yes, I can establish the connection. But at the point when the GUI asks for the network connection the interface does not have the IP address yet. I verify this on another console with 'ifconfig' and 'ip a l'. In the %post section I can do wget and other things, so there does not seem to be the problem. And once I confirm the eth0 interface in gui it gets the ks.cfg network config and install with the configured repo works. Still I think the repo command cannot be used because I don't have the interface configured on kernel command line to get the ks.cfg. I use the local floppy disk with 'ks=floppy' ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Hi, I'm in the middle of migrating our oracle servers to RHEL and C6; while testing ntpd I'm seeing time resets. I see in sysconfig/ntpd the option g is set which means huge offset is one time ignored. But my understanding of ntpd is, it slows or accelerated kernel clock but does not make huge jumps...

NSF files are a proprietary database format used by Lotus Notes and Domino, very complex, there's a pile of versions, and they are totally opaque. Pretty sure that if they are being accessed or updated while being copied the copy is invalid, so yes, some form of snapshotting is required. commercial backup software uses Domino/Notes APIs to do incremental backups, for example http://www.symantec.com/business/support/index?page=contentid=TECH46513 If there is a command-line way to generate an incremental backup file, backuppc could run it via ssh as a pre-backup command. Yes, there is commercial software to do incremental backups but I do not know of commandline options to do this. Maybe anyone? Les is right, I stop the server, take the snapshot, start the server and do the xdelta on the snapshot NSF files.

Yes, guys, exactly what I meant was filling unused space with zeros. The linux tools to compress and transfer cannot read the ntfs data structure and compress every garbage. But if unused blocks are filled with zeros one can achieve much better compression. I looked into sdelete.exe, this really is helpful but obviously works in running instance.

Re: [CentOS] Amazon EC2 - building a minimal centOS ebs bootable image

Looking to build CentOS based micro EC2 instance bootable from Amazon
EBS. Want that the image be minimal, so that I can add only the rpms I
want.
Despite looking could not find a way to import a CentOS image from
scratch or an existing minimal CentOS image that is bootable from EBS.
My server must must persist, as I cannot handle issues with a dynamic
server, so I want to use a server that can boot from EBS.
Hi Sanjay,
there are plenty of howtos to get centos in the cloud - google is your
friend.
But one note: since C5.5 you do not need Amazon's kernel+initrd anymore,
the Centos shipped xenblk and xennet modules work just fine. And finally
amazon ships a thing as boot kernel that behaves like pygrub and reads
the grub.conf of your image and starts the inside configured kernel.
I had to use this cmdline to make the initrd:
KVER=$(uname -a|awk '{print $3}')xen
mkinitrd --omit-scsi-modules --with=xennet --with=xenblk
--preload=xenblk -f /boot/initrd-${KVER}.img ${KVER}
and my modprobe.conf:
alias eth0 xennet
alias scsi_hostadapter xenblk
To get an image into the cloud I did:
- format a 10GiB file with ext3
- install a minimal centos to it (yum with --installroot option)
- put this into S3 as an AMI
- start an instance of it
- clone this to an EBS file with rsync
- make a snapshot of this EBS
- convert this snapshot to an EBS AMI
- use your EBS instances...

Looking exactly for something like this...but more detailed. I have slow dsl...so I would rather use somebody else's centos image to build my own. Have found many howtos but all seem to be for just for copying some other ami and then reconfiguring it, or else they are too technical for me to dive into. For building the image: http://bodgitandscarper.co.uk/category/amazon-ec2/ But as I said I had to use another mkinitrd cmd. The image will be compressed once you upload it, mine was around 300mb.

Re: [CentOS] XFS or EXT3 ?
Am 03.12.2010 13:55, schrieb Keith Roberts: There was a similar thread about which is the best FS for Centos. I'm using ext3, and wondered if XFS would be more 'data safe' than ext3. I had a 100GiB ext3 partition, and it took up 1.75GiB for FS administration purposes. I reformatted it to XFS, and it only used 50.8MB! Just yesterday we had the case of hitting ext3 limits - a folder can only contain 32k subfolders. So I had to create a XFS container, to hold the amount of data.

[CentOS] redirecting time output
Hi, am trying to pipe output from time command and output from a shell script to the mail program. So far it's not working as expected... # time echo test 21 | mail -s timetest m...@mail.com real0m0.126s user0m0.000s sys 0m0.000s The time command writes to stderror, but here the redirection seems to apply to the echo command?
