Re: [CentOS-virt] Can't create new Xen domains using libvirt on CentOS 6.5
Thanks for pointing me to xm dmesg. That was the missing part. The server has one of the AMD CPUs affected by this: http://lists.xen.org/archives/html/xen-announce/2012-06/msg2.html So we had to add allow_unsafe to the boot line. Now Xen works fine.

Re: [CentOS-virt] Hey
I have used xen over kvm and others for a while. It was what I just started using first years ago. With Xen I could manage domains and my system seemed like a real server. KVM just seemed like a command line trick to me. (I know it is not especially since its integration into the kernel.) xenserver is pretty sweet and there are some big products built around it. Citrix loves it too. OpenStack is neat: http://www.xenproject.org/presentations-and-videos/video/xpus13-rackspace.html I was disappointed when redhat dropped xen :/ I mean now there is an entire project around keeping xen on centos, etc. This one. In the end xen just seemed more strait forward. ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

I used to use Xen. As far as I can tell, I published the first SRPM's for it, back when it was open entirely open source, before Citrix bought it. As far as I can tell, the open source Xen suffers from many of the same problems as KVM and qemu. Namely, the gui and command line tool, libvirt, is poorly built overburdened debris that does not fulfill *anyone's* standards of a good configuration tool, especially the open source GUI guidelines written by Eric Raymond in his Luxury of Ignorance essay. That said, Xen suffers no more from it than KVM does. It also doesn't have the stunningly painful requirements to override NetworkManager and manually configure the bridge device, as documented by me years ago at at https://wikis.uit.tufts.edu/confluence/display/TUSKpub/Configure+Pair+Bonding+and+Bridges+for+KVM+Hypervisor. Obviously on this list there is mostly Xen users, and I feel like I must be missing some great advantage so I am curious, those of you who prefer Xen, why? Personally, I use Virtualbox or corporate supplied VMware these days. Not becuase I don't like open source tools, but because I prefer to spend my subtle confifation time more usefully than working through libvirt and NetworkManager manual, poorly documented, unintegrated confuiguration steps just to get things to work normally. ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

[CentOS] NIS or not?
Hi all, We're getting to a point in our linux environment where it's starting to be cumbersome to keep shadow and passwd-files up-to-date for the users to login on each computer. Scripts can only get us so far. 8-/ I've looked a bit into central login systems for linux, and NIS and LDAP seem to be prevalent. NIS being the simpler-to-setup solution for small to medium networks as I understand it, while LDAP is the more modern and scalable solution. See eg http://www.yolinux.com/TUTORIALS/NIS.html or http://sysadmin-notepad.blogspot.se/2013/06/nis-server-setup-on-rhelcentos.html. NIS-wise, what is a small to medium network? We have currently about 20-30'ish linux clients and servers, and the environment is not likely to increase much beyond this point. Is a 30ish-computer setup, a small network? The only thing I'm trying to accomplish is a system which will allow me to keep user accounts and passwords in one place, with one place only to administrate. NIS seems to be able to do that.

[CentOS] Recent version of Latex
I've moved most of my user's PCs from OpenSuse (11.x, unmaintainend now) to CentOS 6.4. On my old OpenSuse latex was texlive-latex-2010 and current version on CTAN is texlive-2013. But on CentOS 6.4 I've only the old texlive-latex-2007 and several sty files available on my previous config are not available now and users cannot compile their previous documents. Is there a Yum repo from where I can install a more uptodate latex environment for CentOS6.4 ?

Re: [CentOS] NIS or not?
Hi Sorin we use here LDAP authentication and mail-control since more than 10 years. At that time, we did the conversion from passwd/shadow to LDAP using the tools on http://www.padl.com/download/ which are still available, probably in a newer version... To represent a person or a service in LDAP we use the objectclasses: objectClass: account objectClass: posixAccount objectClass: top objectClass: shadowAccount objectClass: mailRecipient To represent a mail user for postfix we use the objectlcasses: objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson objectClass: qmailUser To represent a Domain which we serve mail-wise we use the objectclasses: objectClass: qmailControl objectClass: top We also have developed an LDAP via Web Interface, which we use exclusively for LDAP administration. We have two LDAP servers, syncronized via syncrepl. suomi On 2014-01-28 10:02, Sorin Srbu wrote: Hi all, We're getting to a point in our linux environment where it's starting to be cumbersome to keep shadow and passwd-files up-to-date for the users to login on each computer.

In either case if it's important be aware of the potential security issues related to NIS, mainly the clear text passing of the password which is what pretty much doomed it. Depending on how ansi your users get I would recommend a slave server as well, you might also consider using autofs to mount the user's homes. The biggest potential problem that you might run into when you first implement NIS is to take a look at the uid of all the users on each host, you will need to ensure that they are the same before you start NIS or else it will be a mess for the users because they won't own their own files.

Re: [CentOS] NIS or not?
We have been using NIS for over a decade on our network, and it has been an effective solution. The network spans several subnets, and we have been able to deploy slave NIS servers on the various subnets. The reason for this is several fold: Quicker response for login and other domain requests Network policy requires slave servers to be on subnets to reduce network traffic. While the security is not as strong as it is for the LDAP solution, as long as you are employing NIS on an internal network, you should be all set. -Original Message- From: centos-boun...@centos.org [mailto:centos-boun...@centos.org] On Behalf Of Sorin Srbu Sent: Tuesday, January 28, 2014 4:03 AM To: CentOS mailing list Subject: [CentOS] NIS or not?

Re: [CentOS] NIS or not?
Where I work we use NIS + Kerberos (Active Directory). We have about 150 machines at our site. It works quite well, as someone said, the big draw back to NIS is that it sends passwords insecurely, but if you use Kerberos for authentication it's really quite easy to manage.

I used NIS for many years while working on Sun Solaris and it worked extremely well, although when it breaks it can be a real challenge to figure out the problems. I don't know how well it's implemented in Linux, bound to be a bit different than Solaris. In either case if it's important be aware of the potential security issues related to NIS, mainly the clear text passing of the password which is what pretty much doomed it. Yeah, that last bit made me squirm over here. I don't feel good about that, even though the linux machines are all pretty much localized to one spot, so that hardly any traffic goes out of the department. With all of that said I do think though that LDAP would be a better solution although I've not used LDAP. Good luck with it either way. Thanks.

The network spans several subnets, and we have been able to deploy slave NIS servers on the various subnets. The reason for this is several fold: Quicker response for login and other domain requests Network policy requires slave servers to be on subnets to reduce network traffic. While the security is not as strong as it is for the LDAP solution, as long as you are employing NIS on an internal network, you should be all set.

It's authorization that is currently done by hand and checked with a manual script. (I needed that for the secure mount options NFSv4 provides.) I sincerely hope it's easier to set up and administer and upgrade than native LDAP. In '06, after a discussion with the other admin and manager I was working with at that job, I volunteered to set up openLDAP. Let's just say that the tools were NOT vaguely ready for prime time, though I did find that running webmin helped a *lot* to get it working. I know you can find a horror story for any piece of software on the Internet, but my impression is that LDAP has an unusually high number of scary-sounding anecdotes. I know random Internet blogs forum posts aren't really authoritative, but they do give me a little trepidation regarding LDAP. We have an in-house written set of scripts that administer relevant configuration files, including /etc/passwd. It copies the correct version of that file (among many others) to each host, and shell of /bin/noLogin works just fine. Why set the shell to /bin/noLogin, rather than simply not create that user's /etc/passwd entry? I don't have /bin/noLogin on any of my systems - I assume you deliberately specified a non-existent program for the shell? What's the difference between setting the user's shell to a bogus program versus something like /bin/false? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

HOWEVER, you can see a real performance hit. my usual routine is parted -a optimal mklabel gpt mkpart pri ext4 0.0GB 3001.0GB q and that aligns them for optimal speed. The 0.0GB will start at 1M - the old start at sector(?) 63 will result in non-optimal alignment, not starting on a cylinder boundry, or something. Note also that parted is user hostile, so you have to know the exact magical incantations, or you get this is not aligned optimally, but no idea of what it thinks you should do.
