Changing local password after NIS on SuSE V8
I have several SuSE 8 systems yet to convert to SuSE 10. The V8 systems all use NIS logons. For my local ROOT account, I cannot change the password. Linux tells me it has been changed but it lies! My NIS logons work OK. Any ideas Lea Stahr Senior Systems Engineer Linux and zLinux Navistar, Inc. 630-753-5445 [EMAIL PROTECTED] -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
Re: Confused about PAV and linux
PAV should only be used when necessary - for MOSTLY READ devices only. For devices with write activity, I have examples where I/O response times get worse, not better. Assuming your objective is better service? keep it super simple, there are many more important places to focus when it comes to performance.

We have 2105 ECKD DASD running off it with 3390B and 3390A definitions. We see PAV bases and aliases under z/VM no prob. - No FCP at this point as FCP from the 9990v to the z9BC requires a San volume controller for IBM to support it. We don't have the SVC. Straight FICON ECKD is all we got and most are MOD9s (We wll be going bigger if we stick ECKD). I have done some reading. Some from old sources, some from new.I am a bit overloaded now. Am I correct that in order to get PAV working on the linux guest I only have to vary the volumes online to guest itself and the linux DASD driver will handle the PAV when required? I really don't have to mess around with multipath, mdadm or EVMS (we have some SLES)? In my testing with RHEL5 I can vary online the base and alias devices and all appears ok. The DASD driver finds which are the alias and the bases and the UIDs all point to the same device. Am I on the right path here? D.

Berry van Sleeuwen wrote: As for cost, yes, a mainframe will cost you more than a PC, but can you run as much workload on a PC? You would need more PC's to run the same workload and that would increase the cost to the same level or even above that. The problem is that you can't compare a single PC with a single mainframe and then say that the mainframe is more expensive. It is just like comparing a car with a truck. I wouldn't buy a car and then expect it to move 40tons of freight. So why then expect a PC to run the workload of a mainframe? Unfortunatly, most decision makers only know a PC and compare the price for a PC they buy at whatever discountstore with the price they must pay for a zseries machine. They ignore the fact that a mainframe can run much, much more workloads and is much more scalable than a PC. It's been said fairly regularly on this list, that if your workload is I/O intensive, zSeries is a good choice. If it's CPU intensive, look at something else. Maybe intellish, maybe Power, maybe something else. Have a look at top500.org to see what folks who are doing serious number crunching use. Intellish and Linux get mentioned fairly often, zSeries and its predecessors never. -- Cheers John -- spambait [EMAIL PROTECTED] [EMAIL PROTECTED] -- Advice http://webfoot.com/advice/email.top.php http://www.catb.org/~esr/faqs/smart-questions.html http://support.microsoft.com/kb/555375 You cannot reply off-list:-) -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
Question about adding a temp ip addr to Linux
I need to eventually move my linux boxes . I know I can do this dynamically and if thisngs fail reboot the system and be back to square 1. I want to test some(a) new address(es) first on the test box. If I do an: ifconfig eth0:1 xx.xx.xx.xxx netmask xxx.xxx.xxx.x will this permanetly change the address (which I don't want)? Is this the correct command?

Interesting shell function?
I just had to post this. Sorry if it is stupid. I just write a little
shell function which was inspired by a Tech Tip on page 56 of the Dec 2008
Linux Journal magazine. I call it smart_cat because it does the
equivalent of a cat command, but invokes the appropriate command based
on the last qualifier of the input file name to, hopefully, properly
process the file (e.g. uncompress it). I source this in my .bashrc
file.
function smart_cat()
{
local i
for i in $@;do
case $i in
*.gz) zcat $i
*.bz2) bzcat $i
*.lzma) lzcat $i
*.Z) zcat $i
*) cat $i

done

Similar things have been done in the past with (at least) the less command. If you're running on SLEx or openSUSE, take a look at the LESSOPEN environment variable, and the script that it invokes, /usr/bin/lessopen.sh (on Slackware systems, this is /usr/bin/lesspipe.sh). If you wanted to get even fancier, you might use the file command to figure out what the file type is without depending on trailing filename qualifiers.

Re: NFS Lockd daemon consuming large amounts of CPU
Hello list, I found the problem. On the NFS client system, there was a VSFTPD process that had been sitting there for a while consuming a large percentage of the CPU on that system. I did a kill -9. On /var/log/messages, I received an unexpected lock response message. When I looked back on the NFS server, the lockd process was no longer consuming large amounts of CPU.
