There is an immediate need for samba to be implemented on 3 AIX lpars. Attached is the smb.conf file and testparm for dadsp003. Here is the scenario: 3 AIX, 6.1 lpars, dadsp001, dadsp002 and dadsp003. Installed samba 3.0.24 from aix6 cd. Currently installed on dadsp002 and dadsp003. Configured only on dadsp003. The local networks on all 3 lpars are 192....

...mited files. I am using read.delim() to read them, in a loop. I am invoking my code on Linux Fedora 20, from the BASH command line, using Rscript. The code I'm using looks like: arguments <- commandArgs(trailingOnly=TRUE); # initialize the capped_data data.frame capped_data <- data.frame(lpar="NULL", started=Sys.time(), ended=Sys.time(), stringsAsFactors=FALSE); # and empty it. capped_data <- capped_data[-1,]; # # Read in the data from the files listed for (file in arguments) { data <- read.delim(fi...

Can anyone point out some AIX specific downloads for Puppet AIX - rpms, source, etc - also any docs???

Has anyone had luck getting Winbind from Samba 3.0.11 to compile and authenticate users telnetting (or ssh'ing) into an AIX lpar? If so, what'd you do? :) I've compiled kerberos and openldap, both installed. Able to run the configure script for Samba, pointing LDFLAGS and related to the correct location for the openldap libraries. I've been unable to get Samba compiled correctly when adding --with-pam to...

Add two corresponding helper functions to support pv-qspinlock. For normal use, __spin_yield_cpu will confer current vcpu slices to the target vcpu(say, a lock holder). If target vcpu is not specified or it is in running state, such conferging to lpar happens or not depends. Because hcall itself will introduce latency and a little overhead. And we do NOT want to suffer any latency on some cases, e.g. in interrupt handler. The second parameter *confer* can indicate such case. __spin_wake_cpu is simpiler, it will wake up one vcpu regardless of i...

So currently PPC has a fairly straight forward test-and-set spinlock IIRC. You have this because LPAR/virt muck and lock holder preemption issues etc.. qspinlock is 1) a fair lock (like ticket locks) and 2) provides out-of-word spinning, reducing cacheline pressure.

I should start off by saying that I know a lot more about linux than I do z/series hardware.... I've tried centos 3.3 and 4.4 for s390 and s390x, if it make any difference.... Trying to install 4.4 on an lpar on a z9-BC and having trouble figuring out how to get the OSA adapter working. I've been told that when I ftp-boot from the iso image, I should choose "eth" for adapter type, and enter "0xe38,0xe39,0xe3a" for the addresses. For the additional parameters, I've tried:...

I can browse the files in the share with no problem but when I open any ty...

Hi, We are trying to setup XEN testbed on Thamesblue supercomputer which has IBM JS2X blade servers. I know that XEN 3.2 was the last release which supports PowerPC. We want to give it a try now. We are running SLES 10.2 and Gentoo on these blades. Can anyone please tell me which Pv_ops kernel should I use for setting up XEN 3.2 on powerpc? Thanks. Best Regards, Hassan
