What's wrong is you can't read man pages or research on your

Re: [CentOS] Centos 5.5 - Kernel Panic while booting.
Hi,
When I make DVDs of Centos and any others for that matter, I take the
following steps:
1. Find an official torrent if possible. (Centos has torrents for the
DVD. Unfortunately no Jigdo so far as I know.)
1.1 Torrents come with checksums and the torrent app I use will check
the downloaded file against the checksums. Otherwise find a stable
mirror close to where you are for better speed.
1.2 If you cant get a torrent find out if the distro vendors offer any
other options. IE: Jigdo, zsync etc. etc. I usually try for one of
these before going for a strait FTP download. FTP downloads often fail
and are not always recoverable in the event of an interruption. Jigdo
is my favourite as each and every package and file is downloaded and
verified and then the DVD image (.iso) made up from all the packages.
It is basically a self checking system and has proven to be very reliable.
2. Once the file is downloaded do a binary checksum using the official
checksums found on the vendors homepage or mirror you downloaded from.
Information on how to call sha512sum or any checksum tool to make it do
a binary level checksum can be found in the man pages. (sha512sum -b
filename.iso)
I always go for the largest checksum algorithm provided. IE: SHA512SUM
if available otherwise SHA256SUM, SHA1SUM or as a last resort MD5SUM.
If this passes proceed to step 3.
3. Burning the DVD. This step is the trickiest part to get right.
3.1. Find **reliable** media. Always choose DVD-R. Go with a named
brand. I usually go for spindles of 50 or less. I have found that the
100 unit spindles get a bit heavy on the ones at the bottom and I am
unsure of the effect shipping and handling has on them.
3.2. Use the following wodim command:
/usr/bin/wodim dev=/dev/sr0 driveropts=burnfree fs=14M speed=4 -dao
${ISO_FILENAME} where /dev/sr0 is your DVD device and ${ISO_FILENAME}
is your iso you are trying to burn.
to burn the DVD at the slowest possible speed your DVD burner will go
for. Use DISK AT ONCE (dao) to write the whole file in one go. Wodim
will close the disk session after burning. I know nothing about using
windows tools to burn DVDs as I do this on Linux.
4. Check the media against the official checksum you used in step 2.
Here are my steps for doing this. Again this has to be done right.
Sometimes you will get different results if you try to simply call
sha512sum -b /dev/sr0 where /dev/sr0 is your DVD drive.
4.1. Use the isoinfo tool to retreive the blocksize and blockcount of
the DVD you are checking. (/usr/bin/isoinfo -d -i /dev/sr0 where
/dev/sr0 is your DVD device.)
4.2. Use dd to read the disk using the correct blocksize and blockcount
settings and pipe through the checksum tool.
IE: /bin/dd if=/dev/sr0 bs=${blocksize} count=${blockcount}
conv=notrunc,noerror status=noxfer | sha512sum -b where ${blocksize}
and ${blockcount} are the numbers you retrieved from using isoinfo.
conv=notrunc,noerror come from another post I found once. So far so
good... The dd man page explains that notrunc means do not truncate the
output file and noerror means continue after read errors.
status=noxfer is just to keep the whole thing a little quieter by not
displaying transfer statistics. You can play with these settings if you
like. They have done me fine for over 400 burns since I started doing
this over 2 years ago.
This will produce a checksum you can visually compare with the official
checksum you retrieved from the mirrors to confirm if your disk is good.
I do not know of a better way, without actually installing the OS, of
verifying that the media is good.
I have all this scripted so complete all these steps every time I ship a
DVD to any customer who orders one.
Best regards
David Latham

This was very helpful Akemi...I was loading centos in two other
identical servers today and was having such a hard time loading it from
DVD, DVD appears to be crashing, I even re-downloaded the image 3 times
from three different mirrors and burn them with different applications
(Nero, Roxio, and poweriso), worse case scenario it must be something
with the Memorex DVD Media. Anyway, after two hours of trying I decided
to do a network install and everything went flawless. Good to have many
options, Centos rocks!

Re: [CentOS] Netinstall NFS using local server.
Thank you for the responses, still I don't find an answer. I am learning Centos from the ground up, I need to learn how to install this via NFS. I am aware that FTp and HTTP and options available, but what is the point of having NFS during the install if it doesn't work. I need to find a way to get the installation going at least for learning purposes. If you have any clues give me a hand, I am not planning to have to running in my environment but at least i would have the concept under my belt. Thank you.

Now I want to do a NFS install from a local server and a client. Both, client and server are in the same vlan 10.14.10.0/255.255.255.0. *Don't*. From painful experience, the NFS is very fragile to local network interruptions and tends to leave unreleased mountpoints reported on the NFS server, which makes getting meaningful monitoring of the server quite awkward. The server has a static 10.14.10.15 address and the client gets its own address via DHCP. I download the DVD image from one of the mirrors and placed it under /centos-media/centosdvd32/DVD/CentOS-5.5-i386-bin-DVD.iso which is a dedicated partition on the server to hold all images. After that I exported the usual entries under /etc/exports and reloaded NFS using /sbin/service nfs reload. This is what my exports file looks like: [r...@zeus DVD]# cat /etc/exports /centos-media/centosdvd64 10.14.10.0/255.255.255.0(ro,sync,all_squash) /centos-media/centosdvd32/DVD 10.14.10.0/255.255.255.0(ro,sync,all_squash) After doing so, I also modified the entries under IPtables to allow traffic in 111 and 2049 at the UDP/TCP level and restarted the service as shown bellow. Oh, dear. This sort of thing is requirement is why you simply run a light FTP or HTTP server and make it accessible that way. It's nominally slower, but the difference is hardly noticeable.

What's wrong is you can't read man pages or research on your
own. man bash; your problem is covered there.
It is there, but it's pretty obscure. A hint is that 'if' wants to execute
something, and in the old days /bin/test and /bin/[ used to be links to the
same
executable. These days the executables are in /usr/bin and not linked (don't
know the reason for either...) but they are also shell builtins.

[CentOS] if you install cgi programs from rpm, how to configure for actual use in /var/www/html ?
In Centos 5.5, I've had this same experience over and over. I have no trouble installing CGI programs the old fashioned way (untar into /var/www/html and configure), but don't like un-rpm managed files floating about. So I can install, for example, phpMyAdmin, from EPEL. That phpMyAdmin RPM drops files into a bunch of locations, the php files are under /usr/share/phpMysql and then there are also: /etc/httpd/conf.d/phpMyAdmin.conf /etc/phpMyAdmin /etc/phpMyAdmin/config.inc.php and this: /var/lib/phpMyAdmin /var/lib/phpMyAdmin/config /var/lib/phpMyAdmin/save /var/lib/phpMyAdmin/upload In order to make this actually work on the web server, I copy the directory /usr/share/phpMyAdmin into /var/www/html and then I edit the /etc/httpd/conf.d/phpMyAdmin.conf. Then it works. Then a new version of the phpMyAdmin RPM is released on EPEL, it gets installed, and I have no idea what I'm supposed to do to keep my thing in /var/www/html working. I had the exact same experience with the mediawiki RPM from EPEL. It installs its files into /var/www/ var/www/mediawiki116 and /usr/share/mediawiki116 The web server required everything to b e under /var/www/html/, so I copy files in there. The mediawiki116 documentation does not mention this problem, but I've googled long enough until I found this, which agrees with me that it is necessary to copy the files over in order to use the media wiki. http://www.wikihow.com/Install-MediaWiki-on-Fedora Unfortunately, now the upgrade path is obscured.

Re: [CentOS] SELinux - way of the future or good idea but !!!
I quit using Fedora a couple of years ago, largely because I felt as
though I was being used as an SELinux guinea pig. I spent days and
says trying to work around selinux problems, until I eventually just
turned it off.
I'm not a professional sysadmin, but I know many of them who think
SELinux is still just not workable enough for actual production
systems.
I just installed the release version of RedHat 6 and wanted to use
mediawiki and a couple of other CGI php programs. All of those
programs that require email capability via sendmail/postfix do not
work with SELINUX turned on. Some programs are nice enough to pop up
a sendmail failed message, but not all.

It is a known bugzilla, there's supposed to be some fix in the way,
but it has turned into such a big hassle for us here that we've turned
selinux down to PERMISSIVE mode, just so things will work.
SELINUX generates such a massive amount of output in /var/log/audit
that I would never be able to notice what fails and what doesnt, some
programs silently die with SELINUX rejects them. For example, I
created a bunch of accounts in mediawiki that require email
confirmation. Use of sendmail was rejected, (silently), and so the
users's can't log in. Grrr.

My cat /proc/scsi/scsi outputs the following: Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: transtec Model: PV610F16R1C Rev: 373I Type: Direct-AccessANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 01 Lun: 00 Vendor: HP Model: Ultrium 3-SCSI Rev: D22D Type: Sequential-AccessANSI SCSI revision: 03 Host: scsi1 Channel: 00 Id: 05 Lun: 00 Vendor: HP Model: Ultrium 4-SCSI Rev: B54Z Type: Sequential-AccessANSI SCSI revision: 05 It is my understanding that there should be TWO devices for the loader, one for the tape drive and one for itself. From reading around, it seems that it's lacking Multiple LUM support. My question is, are more recent versions of CentOS enabling that by default? Either compiling kernel modules or doing a full upgrade of the system are big jobs in my case, but I'd prefer the upgrade if 5.5 works out of the box. Or do I really need to recompile kernel, enable max_lums in modprobe.conf, etc?

Re: [CentOS] if you install cgi programs from rpm, how to configure for actual use in /var/www/html ?

I have no trouble installing CGI programs the old fashioned way (untar into /var/www/html and configure), but don't like un-rpm managed files floating about. So I can install, for example, phpMyAdmin, from EPEL. That phpMyAdmin RPM drops files into a bunch of locations, the php files are under /usr/share/phpMysql and then there are also: /etc/httpd/conf.d/phpMyAdmin.conf /etc/phpMyAdmin /etc/phpMyAdmin/config.inc.php and this: /var/lib/phpMyAdmin /var/lib/phpMyAdmin/config /var/lib/phpMyAdmin/save /var/lib/phpMyAdmin/upload In order to make this actually work on the web server, I copy the directory /usr/share/phpMyAdmin into /var/www/html and then I edit the /etc/httpd/conf.d/phpMyAdmin.conf. Then it works. Then a new version of the phpMyAdmin RPM is released on EPEL, it gets installed, and I have no idea what I'm supposed to do to keep my thing in /var/www/html working. I had the exact same experience with the mediawiki RPM from EPEL. It installs its files into /var/www/ var/www/mediawiki116 and /usr/share/mediawiki116 The web server required everything to b e under /var/www/html/, so I copy files in there. The mediawiki116 documentation does not mention this problem, but I've googled long enough until I found this, which agrees with me that it is necessary to copy the files over in order to use the media wiki. http://www.wikihow.com/Install-MediaWiki-on-Fedora Unfortunately, now the upgrade path is obscured. When RPM updates its files (scattered over the file system), what to do? --- Paul E. Johnson You're right... what you are doing now is unmaintainable. What you should be doing instead is configuring apache separately for each software you install. If mediawiki installed itself in /var/www/mediawiki, then you would set up an alias to that in the apache config, something like Alias /wiki /var/www/mediawiki. When you access the URL http://example.com/mediawiki, the files will be served from the default install location. You should also take a look at what's in /etc/httpd/conf.d to see how to use the more modularized approach that is the default way apache is installed with CentOS. There might even already be some default conf files from the ones you installed from rpm. Use rpm -ql packagename to see all the files installed by that package. There might be some clues in there about sample apache configs. You might find docs about this somewhere in /usr/share/doc/packagename, but I'm not aware of any documents that actually explain this approach other than reading through the default apache configs. Maybe someone else can enlighten. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] using kvm
From what I remember -cpu is to tell the vm what cpu extensions are available. I always just use -cpu host which has kvm pass in all the cpu extensions that the host processor has. Using WindowsXP mode on a windows 7 VM sounds dirty. XP mode used to require virtualization hardware, now it doesn't. Perhaps passing in a cpu that doesn't have virtualization extensions is the way to make windows go the non-hardware route. I would expect the performance to be abysmal, but it would be a neat trick.

When I checked the ISO sha1sum it didn't check the posted figure under the centos.org, so I thought something may be wrong witht hat DVD ISO.

Anyone recomended a good screen capture application to do this task, after I create it I will posted in youtube for all to see it. Thank you all and don't forget to check all your sha1sum or md5 keys from DVD or CD ISO, it looks like we can't trust the actual mirrors. Thank you again. NFS install is mega fast in a 1Gbps network.

That's still ambiguous. Does duplicate mean exactly two instances with
case insensitive matching? I think that's what your script does. Of
course in a single directory, you can't have exact duplicates...
Do you mean exact duplicates of a basename found anywhere down a tree,
your case insensitive match limited to one instance within a single
directory, or ???

It is a known bugzilla, there's supposed to be some fix in the way,
but it has turned into such a big hassle for us here that we've turned
selinux down to PERMISSIVE mode, just so things will work.
SELINUX generates such a massive amount of output in /var/log/audit
that I would never be able to notice what fails and what doesnt, some
programs silently die with SELINUX rejects them. For example, I
created a bunch of accounts in mediawiki that require email
confirmation. Use of sendmail was rejected, (silently), and so the
users's can't log in. Grrr.
Turn on the httpd_can_sendmail boolean. We do not want all apache
servers to be able to send mail by default.
# setsebool -P httpd_can_sendmail 1
man apache_selinux
...
SELinu policy for httpd can be configured to turn on sending
email.
This is a security feature, since it would prevent a
vulnerabiltiy in
http from causing a spam attack. I certain situations, you may
want
http modules to send mail. You can turn on the httpd_send_mail
bool?

Re: [CentOS] Netinstall NFS using local server.
ok, playing around with netstat I figure all the ports that need to be open in iptables for this thing to work, I figure having the firewall down was too big of a risk so why not figuring out the ports and opening them in iptables and sharing the knowledge with you guys. The following ports are to be open: 111 tcp/udp 32803 tcp/udp 32769 udp 892 tcp/udp 875 tcp/udp 2049 tcp/udp If I only mentioned tcp or udp after the port it means either or both, if you see one/two it means both protocols must be enable.

Anyone recomended a good screen capture application to do this task, after I create it I will posted in youtube for all to see it.

Re: [CentOS] way to replace DELL PERC 6/E card???
OK, good point and I apologize for seeming rough, though the phrase flying blind is not an really an insult. Your post sounded a bit like someone who hasn't dealt with servers much. The typical answers for something like this are read the manuals, and call support to get a replacement if you have bad hardware. As you have over 100 Dell servers there's a high likelihood that you got a few bad ones, so I would just replace it and move on. There's really not much else to do.

They have a yum repository where you can yum install the software. Most likely the card performed a battery relearn cycle where it discharges and recharges the battery. During this process the battery level drops and this causes the cache memory to become disabled. It also sounds like you already got some new cards, which may have been a waste of money.

No, it looks like mount does not recognise the '\' character as an escape character. Thanks for all the replies to my question. I'll just have to put things all on one line.

I thought they've all done that for decades. OP wants to use 1+ lines joined by '\' to be read as one line by mount(8) et amice so that horizontal scrolling and automagic wrapping aren't needed.

[CentOS] centos 5.5 install + intel raid
Hi all, Installing 5.5 on a fresh system having an Intel RAID. My 2 drives are configured as a mirror within the Intel BIOS. When starting my install, Anaconda throws an exception. After a brief goog, I see one possible fix is - at the install prompt, type; linux text nodmraid This is fine and all but Centos sees 2 disks at this point rather then 1 which is what I thought the Intel RAID controller would present to the OS. I am pretty much tarded when it comes to installs as I usually boot of a DVD, enter some choices based on requirements and off I go. I once compiled a network driver into the initrd and remade my boot disk but that seems beyond me now. Any help is greatly appreciated. - aurf ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

What's wrong with my one-liner?
What's wrong is you can't read man pages or research on your
own. man bash; your problem is covered there.
It is there, but it's pretty obscure. A hint is that 'if' wants to execute
something, and in the old days /bin/test and /bin/[ used to be links to the
same
executable. These days the executables are in /usr/bin and not linked (don't
know the reason for either...) but they are also shell builtins.
The Usenet newsgroup comp.unix.shell is a great place to ask such questions.

Nice. Minor corrections needed:

-qf = --qf

--f = -f

Gahhh. Proportional fonts in this mail interfaces. We hates it, yes,

Good catch, though. But why use '%{VERSION}' when '%{version}' will serve?
