Folks, We've been having occasional issues with failover dhcpd. I went looking for "peer holds all free leases", and happened to run across <https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=610219>, which is rated important, and is supposed to be fixed in 3.0.5-24. Looking at the repo at kernel.org, all I see is what we have, dhclient-3.0.5-23.el5.x86_64.rpm.

Report by Eric Lindblad 30-09-2015 http://www.ericlindblad.blogspot.com The xapian-core-1.2.21 'ambiguous overload' error on the files /backends/brass/brass_check.cc and /backends/chert/chert_check.cc appear to be resultant of a bug reported in gcc-3.3.4, which was fixed for 3.4.2 [Sept. 6, 2004] and 3.5. Bug 16854 - streams missing "long long" specializations on Tru64

Hi Justin, > This looks like something I fixed recently, in r290271: ... ... > The tablegen build adopted USES_TERMINAL for this same reason in > r280748. I applied the 2 patches you mentioned above on my 3.9.1 tree and although the build seems to go along nicely than the earlier reported symptoms I can still see LLVMSupport being built a bit too many times than expected. $ cat

I had to downgrade samba on a rh5.5 instance due to ntlm_auth not working properly: https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=561325 Now, when I add the computer to the domain ('net ads join ?U Administrator') it seems to work, is visible on the AD interface, but the logs show an error: Nov 11 16:03:22 rhclient winbindd[4483]: [2010/11/11 16:03:22, 0]

Hi Folks, I am building LLVM 3.9.1 using the Yocto build system for a cross build. The compiled bins/libs work totally fine on the target machine however there seems to be an intermittent race condition during the build which causes a build failure. On the failed builds I usually see things being linking/compiling twice e.g. Linking CXX static library ../libLLVMSupport.a cd

Hi folks I just installed Centos 5.5. I heard about the new changes in wifi support. I tried a USB wifi card from Netgear, and It works fine. It didn't en Centos 5.4, so that's great news. The problem is I have a Linksys WUSB54GC USB wifi card and I want to make it work. I get this messages in /var/log/messages as soon as I plug it in. Oct 14 22:56:20 lila kernel: usb 1-1: USB

Hi, I just tried x=dom.blockPeek('disk',5,0,buf,0) and it returns AtrributeError: 'module' object has no attribute 'virDomainBlockPeek' I found this bug submission from early 09: https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=492683 Is that still correct are they not implemented. Or did i screw up the command? Thanks, Steve

I am running the Eucalyptus 2.0 cloud computing platform on an up-to-date CentOS 5 using the xen hypervisor.

Hi, There is a strange issue in the CentOS 7.2 libvirtd 1.2.17 service. If there is a symlink in the "/etc/libvirt/qemu/autostart/" which is created before the libvirtd service is started, libvirtd wont start. Deleting the symlink from the autostart folder, then starting the libvirtd service works. Is this a know issue ? We have found this on 4-5 servers. Regards,

First, it fails because the destination directory doesn''t exist. Then it fails because it DOES exist. I really expected one of those to work. So, what am I confused about now?

Hi thanks for the reply. I installed Nut via apt-get, not from source (which I'd rather stick with if possible just for ease of security updates etc) - so I'm not too sure if TCP wrappers are there or available... This could be the problem, am I still able to add the wrappers in with prebuilt packages? Thanks very much once again. :) On 24 November 2016 at 21:51, Roger Price <roger

Hi Manman, thanks for the heads up. I looked into what it would take to produce full struct TBAA metadata from the GCC aliasing info (GCC has aliasing info for struct types, in fact for any type), but it looks kind of tricky. The problem is the "offset" field, which doesn't exist in GCC. In GCC the aliasing information forms a DAG, with a node for each type, plus a special root
