2nd DC, internal DNS: dns_tkey_negotiategss: TKEY is unacceptable
Hi everyone, I'm testing with a Samba4 AD network, and I have some problems with DNS on the second DC, with which I could use a bit of your help. I have an AD with two DC's, both Samba 4.2.3. On the first DC, samba_dnsupdate works fine. With stock 4.2.3 I get the error "TSIG error with server: tsig verify failure" but the DNS updates succeed anyway, and after applying

2nd DC, internal DNS: dns_tkey_negotiategss: TKEY is unacceptable - SOLVED
L.P.H. van Belle writes: > is the time in sync on your servers ? Yes it is. I managed to make it work by specifying the primary DC as nameserver in /etc/resolv.conf of the secondary DC. As soon as I do that, samba_dnsupdate works on the secondary. When I change it back to use the local Samba as resolver, it no longer works. So it is a DNS issue (possibly related to replication

{nlme} Multilevel estimation heteroscedasticity
Dear All, I'm trying to model heteroscedasticity using a multilevel model. To do so, I make use of the nlme package and the weigths-parameter. Let's say that I hypothesize that the exam score of students (normexam) is influenced by their score on a standardized LR test (standLRT). Students are of course nested in "schools". These variables are contained in the

Does certification make sense for non-PE users?
Subject really says it all. I took the practice exam linked from @PuppetLabs and I was a little bit surprised/caught-off-guard by the number of either PE or Console questions, neither of which I''ve ever used :-! I am taking the developer exam though, so I''m sure that will be at least a little different. Does it make sense to take the exam for an "open source puppet

RHCE
I realize this is a CentOS mailing list but because it is based directly on RHEL, I would assume there are a few individuals who frequent the list that have passed the RHCE exam. I plan on taking the exam this March and was wondering if there are any tips you RHCEs out there could provide that may help me. Thanks!

recommended package/docs for analyzing multiple choice tests
Hi, What package would you recommend for analyzing the validity/reliability of multiple choice tests. Doing things such as classical test analysis, factor analysis, item response theory.
