As a workaround, can you boot into your previous kernel? Generally,
when you install a new kernel, the previous couple of kernels are
still there and bootable from the grub menu.
That will help determine if it was, in fact, the kernel, or if
something else has changed. If it works, you can then load additional
tools.

I've done that on one SL6 machine so the application admins can deal

Re: Network question - disable access to an IP without running ifdown ?

The surest way would be to get access to the network switch and disable the port going to the master server. Depending on the switch, a little ssh and expect could do the job (I do that sort of thing with a lot of Cisco switches to collect information). Or you might be able to do it through SNMP. - Bluejay Adametz When life gives you lemons, keep them.

I've been uneasy with that idea as well, although not to the point of
imminent disaster ...
Different sites might have different rules for gaining root access.
Some might not even permit su and require everything to go through
sudo, or some other mechanism, perhaps as part of an auditing/logging
process.
If it needs to run as root, I would just state that as a requirement,
check for that condition, and output a clear error message if it's not
met. Sometimes it's possible to "dumb things down" too much.

Re: Finally figured out what is causing bug 836696
>> Never really cared for LVM. Always used the direct partition approach.

> Well, perhaps I can try to convince you some more.
I never used LVM either, but in my defense, these were/are factory
systems where it was extremely unlikely that the system would grow and
require more storage, and if one did, we'd have to remove the smaller
drives and put in bigger ones.
More recently, I've been tasked with caring for systems whose
requirements are much more subject to change, and LVM has proven it's
value there. This is especially true in SAN or virtual environments
where the storage admins might just say "ok, here's another 100gb
'disk' for you".
So, it depends on your environment as much as your preferences. Yeah,
it takes some getting used to, but so did electric typewriters :).

It's probably the Network-Manager doing that, and this is why I remove
it completely on servers and other machines that only have static IP
configurations. Some applications get ugly if they can't figure out
who they're running on.
I think if you edit the /etc/sysconfig/network-scripts/ifcfg-eth1 file
and change NM_CONTROLLED to "no" that may get the Network-Manager to
leave it alone.

Using tar rather than dd would likely be faster if there's any
significant amount of free space on the source disk. dd will copy all
those unused blocks, while tar will copy just the Useful Data.
The network interface config files
(/etc/sysconfig/network-scripts/ifcfg-*) contain the interface MAC
address. You'll probably need to modify that. It may be easiest to set
up a one-time boot script so this can be set on the destination (B)
machine the first time it boots.
If you use selinux, you may want to touch .autorelabel in the B root
file system so the contexts will get set properly when it boots.

I'm not familiar with REAR, but what we do here is take a live SL CD

Yes, I would expect a firewall to either deny (possibly generating the
'no route' error by explicitly denying the connect), or allow it,
every time.
Are there any routers involved, or are both the home and office
machines on the same LAN, in the configuration where you see the
failures?

If it fails immediately, it could be a router or firewall blocking
something or maybe iptables.
If it takes a few seconds, then it's more likely that the machine just
isn't responding to the ARP request, because it didn't receive it or
it's not listening.

There's probably some additional incantation is needed. But... AHA! I tried building an initrd image using --hostonly. This got me past mounting the root file system and through starting udev. I could see something happening after starting udev before the reset happened, so I started video recording the screen as it failed and going over that frame-by-frame. I found it was the i915 driver that's apparently killing the system. If I blacklist it, the system boots ok. After booting, a 'modprobe i915' results in a reset. I've only been able to catch the following with video (*'s represent stuff I can't make out, as it's not on the screen long enough to get a good frame): [drm[ Initialized drm 1.1.0 20060813 i915 :00:02.0: enabling device ( -> 0003) i915 :00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 i915 :00:02.0 *** 0* can't allocate resources [bogus alignment) [0x*-0*0] flags *** [***] failed to find * tables v** ** *** PCI::04:00.0 *** pdr*[ * enablling support This may be something really peculiar to this box.

6.1, boot & reset
At the risk of asking a real noobie question, how can I troubleshoot
the following?
I just upgraded a machine from 6.0 to 6.1. When booting with the new
kernel, 2.6.32-131.6.1.el6.i686, it starts to boot and then the
machine (a Dell GX280) just resets. Things are moving fast on the
screen and I can't really tell precisely where the reset is occuring,
but looking at a log from a successful boot (with the old kernel), it
looks like the failure is occurring somewhere around the spot marked
below:

If I boot with the previous kernel (2.6.32-71.24.1.el6.i686) the
machine boots fine. If I boot from the 6.1 boot CD, the same reset
happens; the last line I can make out on the screen is something like
"waiting"..."hardware"
Ideas?

Something like:

Or you can out that line in the /etc/yum.repos.d/* files to only

I have a lot of servers that I don't even install X windows on, much

Around here, a large manufacturing site, we use RedHat EL where we

Authentic RedHat in order for that vendor to support us), Scientific

The thing of it is, IMHO, UNIX, and especially most Linux
distributions, give you a whole toolbox full of tools. Yeah, there are
some indispensable tools like your basic screwdrivers and wrenches,
but the neat thing is how you can hook things together, like that
ratchet, extension, universal, and socket, to do things that you would
otherwise have to visit a machine shop and get a custom tool made at
considerable expense in time and money.
The real value is in all these little command-line tools and utilities
that you can string together to make something happen. Case in point:
the other day I decided I needed to decode and re-encode all my ogg
vorbis files. I could have spent an indeterminate number of hours
clicking and dragging 1209 files around. Instead, I spent a few
minutes to put together a little bash script that would do the job
while I tended to more productive pursuits.
bash, python, awk, grep, wget, curl, sed, ping, dig, perl, ... just a
whole tool box full o' fun :).

I came across this posting: http://gstreamer-devel.966125.n4.nabble.com/Alsasink-problem-td3166307.html which didn't really address my issue but got me thinking about bit rates. I ran a problem .ogg file through oggdec and oggenc re-encode it, then did it again matching the nominal bit rate (160k) of the original. Well, whaddya know? The re-encoded files played just fine. I looked at a problem file with ogginfo and it reported: Warning: sequence number gap in stream 1. Got page 3 when expecting page 2. Indicates missing data. Warning: discontinuity in stream (1) Negative or zero granulepos (0) on vorbis stream outside of headers. This file was created by a buggy encoder These files were created on an SL 5.2+updates system using Sound Juicer. The re-encoded files show no errors. To further troubleshoot, I ripped this same CD with Sound Juicer on SL6 to .ogg files. Those files exhibit the skipping problem. These files also snow no errors with ogginfo. I turned loose a bash script to oggdec and oggenc all 1209 of my .ogg files, and that seems to have alleviated the problem, but not quite entirely. I've identified a couple of albums that seem to still have the skipping problem. I just re-ripped one of them to flac and then converted it to ogg vorbis with oggenc. It seems to be playing fine. It begins to look like there's some sort of issue with how Sound Juicer is producing .ogg files. Is anyone else in a position to test this?

SL6: ogg playback in gstreamer/totem/rhythmbox
When playing back ogg vorbis files with a gstreamer application like
rhythmbox or totem, I'm hearing skips or little instants of silence
scattered through the track. If I use mplayer, the same track plays
just fine. Other formats (mp3, flac) play just fine in any
application.
I loaded gstreamer-properties and it doesn't make any difference what
I select for the audio output: autodetect, pulse, or ALSA.
I tried this on two very different machines - my big desktop (where I
noticed the problem), and on a laptop with the same results.
I found a couple of vague references to an ogg playback problem in
Ubuntu, but there wasn't a whole lot of information. One posting
indicated that it may have been fixed in some update or other.
Any ideas? Maybe a gstreamer codec problem? While I could just convert
my ogg's to flac's (storage ain't a problem), it'd be nice to have a
real solution for this.

Ekiga on SL6?
After wrestling with trying to get pidgin to do GoolgleTalk video chat, and further attempts with the GoogleTalk plugin with Firefox, all with very little success, I thought I'd try out ekiga. On two different machines (one laptop, one desktop, both 32-bit), with two different webcams (Logitec and Microsoft) and different sound cards, fresh installs of SL 6.0 + all the latest updates (ekiga-3.2.6-3.el6.i686), ekiga doesn't seem to be able to find any sound or video devices. The only options I get for audio devices is "SILENT" and the only option I get for video is "Moving Logo". Running ekiga with debug output just shows that it's detecting SILENT and Moving Logo when I click detect devices. On both machines both cameras work (tested with cheese) and the audio works fine with a variety of applications (including, sort of, kind of, pidgin). I gotta believe this isn't as broken as it seems to be and I'll probably slap my forehead when I see what I'm doing wrong, but right now I don't see it and googling all over the place hasn't helped.

Re: SL6 livecd and md RAID partitions - danger
I'll try to answer all the questions here in one shot. Wish me luck! :) >mdadm --stop /dev/125 >mdadm --assemble /dev/md0 /dev/sda1 /dev/sdb1 I tried that but still didn't get back to bootable. It's hard to see what went on when the system halts (my thanks to whoever changed the video mode to get more on the screen during booting in SL6!), so I won't swear that it didn't go back to /dev/md0 and something else was awry. In fact, I just tried this now on an old machine with the same config and manually assembling the RAID sets with the correct devices corrected the problem. I'm not sure what went wrong with this yesterday. I may try it again a time or two just to make sure I'm doing this right. Of course, you'll need to know what the correct devices are, but since you've got your system root (somewhere), you can mount it and look at your fstab or look at the filesystem labels, or even the contents to figure out which is which and where it needs to go. >Are your raid partition of the type 0xfd (Linux RAID autodetect) or 0x83 >(Linux)? 0xfd, RAID autodetect. >BTW.

SL6 livecd and md RAID partitions - danger
As part of upgrade planning for my main workstation at home (an updated SL 5.2 system), I booted from the live CD just to see if all the major devices worked. Everything worked :). Unfortunately, that act rendered my existing system unbootable. When I booted from the live CD it found and started my md RAID1 partitions, including my system root partition. Nice, I had all my data there to play with. I noticed that where I had previously used /dev/md0, /dev/md1, etc..., the live CD system had created them as /dev/md122, /dev/md123, and so on, and not in the original order. I didn't think much of this, figuring my regular system would start them back in the original configuration, but apparently some metadata somewhere got changed by the live CD system and now the original system would not get past switching to the root file system with a 'no such device' error. I could see, just before going off the screen, where it had started my root partition as /dev/md125 rather than /dev/md0. I tried a couple of things to recover from this: I tried stopping and reassembling the RAID sets with the desired device names from the live CD system, and repackaging my initrd with device files for the /dev/md12* devices, but no luck. At that point I decided that, since I had already done my backups and was planning on eventually going to SL6, that I'd just push forward with a fresh install of SL6. It took a few hours that I hadn't planned on to get everything back up to speed, and I have one issue yet to work and a couple of minor things to configure. I have another retired box with the same RAID setup and it too, got hosed by the live CD. I'm going to play with this box to see if I can find a way to recover from this.

SL6 text-installer upgrade
In case anyone was thinking of doing this...
I know this isn't supported, but I thought I'd try upgrading a
throw-away 5.4 machine (which, IIRC, has been upgraded from
SL4.something) to 6.0. I had to use the boot disk since the machine
doesn't have a DVD drive. Then I had to give it the boot option
upgradeany to get it to offer an upgrade. This machine only has 512mb
of RAM (I remember when that was a lot), causing it to decline to
attempt a graphical installation and proceed with a text-based
install.
While it was starting the upgrade and it blathered a bunch of "putting
in simple update" messages across and down the screen,
making for an interesting background pattern. Rather amusing in a way.
I have a screenshot of anyone wants to see it.
As for the results of my experiments in upgrading, I don't recommend it.
1. There were a bunch of SL5 packages that didn't get removed, and
apparently a couple of the SL5 packages were considered "newer" than
the corresponding SL6 packages (I later upgraded them with rpm's
--oldpackage option).
2. SELinux seemed to be rather hosed up. Attempting a relabel
generated a lot of messages about conflicting specifications, and
whenever the system booted it'd throw a lot of "operation not
supported" from setfilecon on all the /dev files. Very little would
even start with SELinux enabled.

Save a copy of your xorg.conf someplace and then put it back once the
upgrade is complete. On machines where I have some investment in my
xorg.conf, I keep a copy off to the side just in case something
decides to "work" on it.

Something like:
-A OUTPUT -d nnn.ip.addr.nnn -p all -j REJECT
added to your /etc/sysconfig/iptables file and a restart of iptables
ought to block access to the specified IP address. But that's just
covering up the root cause.

Re: hanging kernel-update on sl5
I'm no expert on this, but would doing, after a hung unstallation, this:
/bin/bash --norc -xv /sbin/mkinitrd --allow-missing -f
/boot/initrd-2.6.18-194.26.1.el5.img 2.6.18-194.26.1.el5
show more precisely where the mkinitrd script is hanging?

Re: apc or tripplite or something else
> Is APC (or some other make) preferred over tripplite as a linux friendly > ups? Is everyone using nut or are the vendor supplied software good enough? I've got a couple of SL 5.0-with-recent-updates machines with late-model APC UPSs connected via USB, and the UPS parameters/status do show up in dbus. I haven't seen any comprehensive software to monitor these UPSs, but then I haven't looked real hard either. - Bluejay Adametz, CFII, A&P, AA-5B N45210 I respect faith, but doubt is what gets you an education. - Wilson Mizner NOTICE: This message, including any attachments, is only for the use of the intended recipient(s) and may contain confidential and privileged information, or information otherwise protected from disclosure by law.

RTNETLINK answers: No buffer space available
I have an SL5 system that I use for various network polling and
configuration management functions. About once or twice a day, a telnet
command, run from an expect script, to a network switch will fail with:
RTNETLINK answers: No buffer space available
I'm not finding a lot of information about this error. Can someone tell me
what's happening here? Is there some parameter I can tweak to tune this
buffer space?
Additional information, that may or may not be relevant, but hopefully
includes what is relevant:
HP Proliant DL380 G3 system, 2gb memory, 2 CPUs.
This system has one Intel e100 NIC configured as an 802.1q trunk to
connect with 6 Vlans, plus one other e100 on another network. I've only
seen the telnet failure going to switches on that one "other"
(non-trunked) NIC. The two on-board NICs and 6 other e100s are not used at
present.
Three times a day, the system uses nmap to ping poll each network and
harvest MAC information. Once/hour it does the telnet thing to each switch
to collect information. Once/hour does some snmp data gathering. These
activities do not overlap.
Every once in a while, the nmap ping poll will report several:
RTTVAR has grown to over 2.3 seconds, decreasing to 2.0
errors while polling one particular trunked network (not the same network
where the telnet failures occur).
I tuned some arp table parameters to accommodate the IP polling:
net.ipv4.neigh.default.gc_thresh1=512
net.ipv4.neigh.default.gc_thresh2=1024
net.ipv4.neigh.default.gc_thresh3=1536
I have another very similar virtual SL5 system with the same parameters
that does not experience the RTNETLINK errors.
