Re: [CentOS] Not Quite Minimal CentOS 6.2
You're right. The stack was there. First, I was inaccurate when I said I installed 6.2. I actually installed 6.0, and later updated via yum. Second, yeah I was able to start the network service, so there was a stack. All I'd get would be the loopback or lo interface, but it was there. But going into /etc/sysconfig/network-scripts was a pain because there was no ifcfg-eth0 file I could play with. That's when I gave up and re-installed, but added more stuff beyond base just to be sure. As for not configuring the network during the install process, I was pretty sure I had. For some reason it didn't take. Maybe I didn't click a save box when I should have.

Re: [CentOS] SSD as system drive - partitioning question
Well, /boot by default, is always a primary partition. CentOS (and RedHat) like to create a logical volume manager (LVM) on a separate primary partition, and typically inside the LVM one can create and modify the rest of the various partitions. You do have the flexibility to create TWO LVM's. You can place one LVM on a primary partition on the SSD, and the other on the hard drive. From within both LVM's you can create your partitions to your heart's content. Or for your SSD configuration, don't bother creating an LVM for that. You can use up to 4 primary partition per storage device (and lots of secondary partitions). So, since you only want to place two partitions total on the SSD, simply create those two primary partitions and utilize them. === Al From: Frank Cox thea...@melvilletheatre.com To: centos@centos.org Sent: Tuesday, April 17, 2012 3:40 PM Subject: [CentOS] SSD as system drive - partitioning question I mentioned here the other day that I was planning to set up a Centos 6 system using a SSD for the system drive and a regular hard drive for a data drive. My plan is to have everything that doesn't change (much) on the SSD, such as /boot, /lib, /bin and so on. I want to put /tmp and /var and /home on the regular hard drive. Now that I'm at the stage of actually setting this up I have discovered that I don't understand enough about drive partitioning to make this work the way that I want it to. Perhaps I'm missing something obvious. I could create separate partitions on the SSD for /lib, /bin and everything else that I want to put there, then put / on the hard drive, but I would really prefer to put /boot and one other partition on the SSD, and one partition on the hard drive. How can I tell the system that I want /bin and friends on the SSD and /home and /var on the hard drive, but still have just one partition on each drive (plus /boot on the SSD)? If I create / on the hard drive and /ssd on the SSD, then putting bin on the SSD would make it /ssd/bin and that would obviously not be what I want to see. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com www.creekfm.com - FIFTY THOUSAND WATTS of POW WOW POWER! ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I can't see how that actually matters because you want them to gain access to the samba server using their accounts and samba requires both a POSIX a SAMBA user and the logical place for a SAMBA user is to have their SAMBA attributes in the same LDAP record. At that point, they could easily mount a SAMBA share on their Windows box using the same account (though Windows passwords use a Windows compatible hashed password).

[CentOS] Installation of 6.0
Some observations. When I installed 6.0 (base install), the installation interface did not guide me through a network configuration. I do static IP addresses, not DHCP. I ended up manually configuring the various /etc/sysconfig files. I forgot to do the GATEWAY configuration and it took me awhile to figure out why I wasn't able to connect to the server from outside the LAN. I also forgot to do the DNS settings. It's deja-vu all over again, going back to the older Red Hat Linux distros. Anyway, I wasn't able to find a configuration program like netconfig to help me out. Seems like a pretty big omission.

I guess it would all depend on what ISO you are using then because I built a new system this weekend using 'CentOS-6.0-x86_64-minimal.iso' and upon reboot I never get anything for first boot. I had to edit my configuration files by hand to get the system online. NetworkManager is a POS and should be dropped. Of course this is my opinion and I stand by it. I wouldn't care.

Summary:
SELinux is preventing cp from creating a file with a context of unlabeled_t on
a
filesystem.
Detailed Description:
[SELinux is in permissive mode, the operation would have been denied but was
permitted due to permissive mode.]
SELinux is preventing cp from creating a file with a context of unlabeled_t on
a
filesystem. Usually this happens when you ask the cp command to maintain the
context of a file when copying between file systems, cp -a for example. Not
all file contexts should be maintained between the file systems. For example,
a
read-only file type like iso9660_t should not be placed on a r/w
system. cp -P
might be a better solution, as this will adopt the default file context for
the
destination.
Allowing Access:
Use a command like cp -P to preserve all permissions except SELinux context.

the the size.
Try rebooting in permissive mode then inspect the avc messages.
Double check the permissions of the mount point before and
after mounting the device.

[CentOS] install of Pod::Simple through CPAN
I'm running CentOS 4.4. I'm trying to install swatch (a log watcher) using CPAN. It's getting hung up on trying to install a dependency, Pod::Simple So before I get too wrapped up in this, I have the following questions: 1. Is there an alternative way to install swatch? I didn't get a hit when I tried yum. 2. I'm not wedded to swatch. Is there another log checker out there that will work with CentOS? 3. Lastly, here's the error I get when I attempt to install Pod::Simple through CPAN: Test Summary Report --- t/xhtml01 (Wstat: 512 Tests: 26 Failed: 2) Failed tests: 24, 26 Non-zero exit status: 2 Files=53, Tests=1095, 9 wallclock secs ( 1.30 usr 0.10 sys + 7.22 cusr 0.78 csys = 9.40 CPU) Result: FAIL Failed 1/53 test programs. 2/1095 subtests failed. make: *** [test_dynamic] Error 255 ARANDAL/Pod-Simple-3.07.tar.gz /usr/bin/make test -- NOT OK //hint// to see the cpan-testers results for installing this module, try: reports ARANDAL/Pod-Simple-3.07.tar.gz Running make install make test had returned bad status, won't install without force Failed during this command: ARANDAL/Pod-Simple-3.07.tar.gz : make_test NO ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

logwatch comes with CentOS and is installed by default. Logwatch doesn't seem to do real-time monitoring of logs. It seems to just write up stats over a period of time you can specify.

If you wish to see the graphical login run 'telinit 5' without quotes which will start it up for you. You will need to be root (or use sudo) to do this. Be aware that changing runlevels may start services you did not have started in the previous runlevel. It may also stop services that you did have running in the previous runlevel. Be mindful of those services. You can edit the various runlevels and also view what runs in each one by using 'ntsysv --level n' n would be the level in question. For instance, 'ntsysv --level 3' will show you and allow you to edit what starts. You may also use chkconfig to accomplish this. If you want to change the default runlevel for your machine you'll need to edit /etc/inittab and change the line id:3:initdefault: (this entry may differ in the number displayed) to id:5:initdefault: (this runlevel starts X11 on boot).

[CentOS] resizing partition
I'm going to have to resize a partition (shrink it) to make room for more swap space. This is actually not too big of a deal, since we're not talking about a system partition (/, /var, /usr, etc), but one where an application resides. So I won't even have to go to rescue mode to do this. I can umount this thing live. (and since I'm working on it remotely, that's important). But this system was not configured with LVM. So it occurs to me, that in dealing with a non-LVM partition(s), if the swap space I want to enlarge isn't next to the partition I shrink, my options would be to: 1. Manually move the other partitions, probably very risky 2. Simply make a second swap space that's next to the partition I shrink.

I successfully configured (ext3) and mounted it, but when I rebooted, the /dev/sdb1 device/partition is seen by the kernel and it shows up with fdisk -l. Nevertheless I get that error. I've tried umount and am informed that /blah isn't mounted. I've tried lsof and don't find a process that's attached to /blah. I also tried fsck -t ext3 /dev/sdb1 which worked (so it detects the ext3 file system). Any other tools to check out? === Al ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Two Instances of Apache; Primary IP / Secondary IP
do you mean making apache use a specific IP when it proxies the request? (you really lost me, so I may be misunderstanding). why do need that at all? whatever IP is used should not matter since the backend will reply over the socket that was opened by the proxy (be it a production proxy or the test proxy). Both IP addresses are actually assigned to the same physical interface (eth1 and eth1:1). The proxy instance is accepting connections from clients using the eth1:1 secondary interface, but the same PHYSICAL interface as eth1. When it turns around and connects to the back-end service, it seems to be using eth1 even though it's listening on eth1:1. Since it's not listening to eth1, the packets are going to the bit-bucket. At least that's my theory. otherwise, the IP is selected by the kernel depending on the destination. so if you use something like ProxyPass / http://10.1.2.3:8080/ in one proxy and ProxyPass / http://10.4.5.6:8080/ each will use the selected IP. Is there something I can do with routing tables that can help? That would require advanced routing. standard routing is based on destination and the source IP is selected by the kernel after the route has been computed (this allows setting the right IP should you have multiple network interfaces...). but you should not need this. In the end, I may just have to either use a separate server or a second physical interface, probably in another VLAN, to make this work. And my idea seemed like such a good one. === Al ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Two Instances of Apache; Primary IP / Secondary IP
Tried the apache group, and no response. Thought I'd try here. I have set up a development environment so that it mimics a production environment. The production environment has a proxy server (apache 2.x) that sends requests onto another back-end apache server, and of course the proxy server serves up pages sent by the back-end. All that works fine. However, in my development environment, I thought that I'd set up a separate instance of apache on the same server, and add a secondary IP address on the same interface. The proxy apache instance listens on the secondary IP, and the back-end instance listens on the primary IP. When I send a client request to the proxy, I get a blank page. When I check the logs, the back-end shows requests coming from the primary IP, and not the secondary IP. My conclusion is that the proxy is sending its outbound traffic on the primary IP address, not the secondary IP address it's listening on. That in turn means that back-end is sending its pages back on the primary IP instead of the secondary, and that means the proxy instance isn't receiving answers to its request. I know that BIND can be configured to send requests on secondary IP addresses. Can Apache? Is there something I can do with routing tables that can help? === Al ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Capturing Packets -- Ethereal
This may be off topic, but I think my ethereal question might be simple enough. I am presently compiling ethereal on a CentOS platform to check it out. But the packets I want to monitor are actually on a different CentOS platform, and I'd rather not install Ethereal on it, if for no other reason I don't have X-Windows installed on that platform. My question is, can I monitor/write packets to a file on the more remote machine, and then analyze the packets on another machine using my ethereal SW? Can I sniff the packets on the remote w/o a full install of ethereal? === Al ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Disk De-Fraging in Linux
A couple of questions. Are there any linux tools that can de-frag an ext2/3 partition? Are there any advantages to doing so if you're running hardware RAID5? Are there advantages / disadvantages if you're running LVM? === Al ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Ext file systems are a different animal all-together. Why? What's different between NTFS and ext2/3 that defragging is needed in one but not the other? === Al ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] CPAN Question
Maybe a little off-topic. But using cpan, I tried to install IO::Compress::Base 2.006. I already had 2.005 installed. For the life of me, I couldn't get it to upgrade. It finally occurred to me to download the .tgz file, and install it that way. That worked. But does anyone have any hints on how to force cpan to upgrade? I even tried the upgrade command, and that didn't work. === Al ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Linux File System w/case-insensitivity
I used to mount some files via Samba which resided on a windows machine on a CentOS box. We moved the files to a NetApp filer, and I was unable to mount those files using either Samba or CIFS. Most of my problems with Samba were related to the (Windows?) password encryption scheme that has not been included in the Samba suite. Even if I use the mount t cifs, it didn't work. So on the NetApp filer, we switched the volume to NFS only (having the volume as both NFS and CIFS also didn't work, strangely enough), and I was able to mount the volume. Fine. But now the complaint is that the files are case sensitive, and doing searches for a particular file is problematical. So the question: Is there a file system that linux can access that's case insensitive? I guess making a LUN off the NetApp filer and formatting NTFS would work. But I thought I'd ask if there's other alternatives. Also, I think that it would have to be writable. I haven't checked, but isn't NTFS mountable read-only by linux? === Al ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
