CentOS 6.3 packages updates options without upgrading.
The specs may have certain dependency on subset of 6.3 packages, but not for all other packages/binaries, as I mentioned earlier. So, to keep things rather intact, we would simply meet requirements by only updating "selected packages only". And, for now, that should be considered intermittent solution until we can safely land to a proper job as you mentioned. So, would there be any

Problem with a domain controller that is located in a separate site

The double quotes are required by SQL if a name is not of the form letter-followed-by-any-number-of-letters-or-numbers or if the name is a SQL keyword like 'where' or 'select'. If you are doing this from a function, you may as well quote all the names. -Bill On Fri, Oct 2, 2020 at 6:18 PM Philip <herd_dog at cox.net> wrote: > The \?2B\? worked. Have no idea why. Can

Problem with a domain controller that is located in a separate site
thanks for the video provided, I watched it, I didn't understand something very well, but still, as I understand it, in order for the sites to start communicating with each other, a linked site link is needed, and also if there is only one dc on the site, we tell him to act as breadgehead, which I did in the screenshots below, but this did not affect the creation of ntdsconnections, but as I

MSI causing softpanics in guest
lspci shows MSI enabled for PCI device. PCI passthrough works fine. However, as soon as the MSI driver for card is insmodded, kernel panics. This is on xen-unstable. Tried the same with xen-3.3.0 which is supposed to have MSI passthrough, but the same guest shows MSI as disabled. Any else seen this bug, or know of a workaround ?

Packet capture to analysis the tinc connection close
I don't know why, but for my case, I reduced the tinc topology from a complex one(which provide layered redundancy) to a very simpled one(one connection), and that connection drop disappeared. Later, let me draw the topology and share the config to you to see if there's any findings of the cause. Guus Sliepen <guus at tinc-vpn.org>于2017年9月14日 周四上午3:20写道: > On Wed, Sep 13, 2017

Performance issues since upgrading to 3.X to 4.X
Hello, I'm a bit desperate so I'm trying to seek help here. Many year ago, I built myself 2 file servers (5 disks enclosure for data, 2 disks enclosure for the OS) on a computer. It was running on Debian 7.11 for years without an issue and I was getting 75MB/95MB when transferring file from it to a Windows client, all having a 1gbs network card. https://i.ibb.co/N618Z4W/Debian-7.png

CentOS 6.3 packages updates options without upgrading.
Hi, IT seems, centos6.3 does no longer get any updates esp security fixes as per readme here: http://mirror.centos.org/centos/6.3/readme Is there updated source RPMs that can be rebuilt and hand patched, for example, nss-util 3.21.0-2 or openssl 1.0.1e that can be safely used on CentOS 6.3? Any other options that you can shed some light on, highly appreciated for above examples. My apologies if

Hi, Thanks for your responses. Unfortunately, there's not possibility in this specific situation to be able to update from 6.3 -> 6.8. But, it would be nice to be able to update specific packages to latest that's available in 6.8 repo at http://mirror.centos.org/centos/6/os/x86_64/Packages/ For example, nss-util-3.21.0-2.el6.i686.rpm
