It depends on the version of Grub. Grub V1 needs /boot to be RAID1 with old metadata (metadata at the *end* of the partition, so Grub just sees a plain ext2/3/4 file system to find vmlinuz and initrd). Note: /boot/efi or the grub fs that Grub2 seems to want cannot be RAID, but you should duplicate the partitions across all of the physical disks in the raid set and arange some other way of "mirroring" them (eg rsync or some such -- does not need to be continious, since these file systems don't change continuiously). I believe Grub V2 understands raid and LVM, so having a separate /boot raid set might not be needed. Things like /boot/efi and grub's on fs still need to exist outside of the raid set and will need "manual" mirroring. > > Simon > > > > > Also HPE is ClearOS.ÃÂ I ran ClearOS6 for years before going with QNAP > > turnkey.ÃÂ Perhaps current ClearOS is better, but it does not handle > > multi-domain email as I need.ÃÂ Or it did not.ÃÂ So I am going to > > install > > my own CentOS variant and iRedMail... > > > > thanks > > > > > > On 1/5/23 13:08, Jon LaBadie wrote: > >> On Thu, Jan 05, 2023 at 08:18:08AM -0500, Robert Moskowitz wrote: > >>> Proliant gen8 does NOT have UEFI. > >>> > >>> So I think this means I better move up to the gen10... > >>> > >> > >> I'm pleased with my Gen 10+ (Plus).ÃÂ Pricer than I thought > >> you want. > >> > >> I like the "no power supply", just an external brick. > >> Quiet.ÃÂ I put in a PCI card to use 2 NVMe sticks, one for > >> system and one for /home.ÃÂ You can also boot from an internal > >> usb port like a thumb drive permanently installed. > >> > >> Carriers for 2.5inch SSD drives work fine so with few fans, > >> no drive motors, could be quite low power. > >> > >> Mine acts as email server, local caching DNS server (dnsmasq) > >> and Amanda backup server. > >> > >> Jon > >> > > > > > > ___ > > CentOS mailing list > > CentOS@centos.org > > https://lists.centos.org/mailman/listinfo/centos > > > > > ___ > CentOS mailing list > CentOS@centos.org > https://lists.centos.org/mailman/listinfo/centos > > -- Robert Heller -- Cell: 413-658-7953 GV: 978-633-5364 Deepwoods Software-- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Looking for a RAID1 box
Just search for a 2-disk 1U x86_64 (Intel or AMD) system that has room for 2 SATA drives (probably a pair 2.5" SSDs). Don't bother to search for RAID.

This means any system that supports more than one disk that you can install Linux on (including CentOS) can be set up with Linux software RAID.

Re: [CentOS] Raspberry Pi 4 and C++ 17
Did you try: sudo yum install gcc-c++ binutils libc-devel ??? Not sure what version of gcc-c++ that will get you. My CentOS 7 VPS has gcc-c++-4.8.5-44.el7.x86_64 on it, so I would assume the above should get you gcc-c++-4.8.5-44.el7.armv7hl. OTOH, my Raspberry Pi 4 build box with Raspberry Pi OS (based on Debian 10) has gcc version 8.3.0 (Raspbian 8.3.0-6+rpi1). Maybe you should just get an up-to-date Raspberry Pi OS image. Then after 'sudo apt update;sudo apt full-upgrade -y' you can do 'sudo apt install g++ binutils libc-dev'.

Also: what BIOS mode is the SATA controller operating in? The SATA firmware in some PCs implement various "weird" modes, including "RAID" (no, not really hardware RAID, just some kind of half BIOS half MS-Windows driver software RAID hack), Make sure the SATA controller is in AHCI mode and not in some other mode.

That assumes that the RPM was *properly* build from source.

No. F33 is just using a newer version of ext4 than C7 understands. You need a F33 live CD or some other "newer" live CD. A C8 Live CD might work.

You need to grab a copy of debmirror, which is just a Perl script, so it should work under CentOS. I don't know where to get a version as a tarball -- I had an available VM running Ubuntu and just installed it there and NFS mounted the mirror disk from the CentOS server. There is a config file for debmirror to control where you mirror from and just what you mirror (versions, arches, etc.). There is a man page and and example config file. You then run debmirror from crontab (eg every day).

Re: [CentOS] KVM vs. incremental remote backups
What *I* do for backing up KVM VMs is that I use LVM volumes, not QCOW2 images. Then I take a LVM "snapshot" volume, then mount that locally / readonly on the host and use tar (via Amanda). Another option is to install Amanda's client on the VM itself and use Amanda to use tar (running on the VM) -- I use the latter to deal with VMs that have a FS that it not mountable on the host (usually due to ext4 version issues -- CentOS 6's mount.ext4 did not like Ubuntu's 18.04 ext4 fs). I have always found using container image files with VMs a bit too opaque. Since you are using QCOW2 images, you best option would be to treat the VMs as if they were just bare metal servers and rsync over the virtual network (ala 'rsync -a vmhostname:/ backupserver:/backupdisk/vmhostname_backup/') and not even try to backup the QCOW2 image files, except maybe once in awhile for "disaster" recovery purposes (eg if you need to recreate th VM from scratch from a known state).

I have no idea what > repos it might be in Right. Some third party repos and/or varous out-of-band "repos" use different package naming / origanizations. *Fedora* often uses "incompatable" package naming WRT RHEL/CentOS. I guess when RedHat migrates a package set from Fedora, there is sometimes package renaming and reorganization. Esp. for things like Perl, PHP, and Python packages (often these are noarch packages), so when you go back to a Fedora repo for something RedHat did not pick up, you end up with this sort of problem (been there, done that). Often the only cure is to grab the .src.rpm(s) and rebuild it(them), after manually installing the various dependencies one by one (including rebuilding them as well, as needed). Often, the low-level .src.rpms build easily enough, so it becomes mostly a bit of tedium. The OP, is probably going to have to install rpmbuild and set up a RPM Build tree. > > > -- Robert Heller -- Cell: 413-658-7953 GV: 978-633-5364 Deepwoods Software-- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] 8.2.2004 Quick recovery and fix for unbootable machines
Question: I have a CentOS 7 VPS. I have not yet had this problem -- I have not yet done an update since this problem showed up.

Since you are formatting iy FAT32, I'm presuming you will be using it in some device (eg camera, mess-windows machine, etc.). You want an MBR partition table -- eg a visit with fdisk or the like. (Actually, unless you have already used fdisk or the link on this card, it should already have a MBR partition table, with one partiton (1) that is the full size of the disk (less the boot "cylinder"), with a partition type of MS-DOS, so all you have to do is: mkfs.fat /dev/sdc1 Once the existing file system has been umounted (see below). > > I have tried "ejecting" the drive and reinserting the card. > I have tried inserting another card, checking to insure > that I could see its file, ejecting that card and > inserting the target card. > If I do not umount it, busy, if I don't, not found. I'm guessing you are using a GUI and the GUI has some "magic" GUI mounter hack that automagically mounts USB disks when they show up. You probably have to turn that off or work around it. I guess umount from a shell will work.

There also various Allwinner A64 boards out there. There are some people in Bulgaria that have an ARM-based (Allwinner A64) "laptop" kit, and sells the parts separately, so one can build a custom "box" with a 64-bit ARM that is not specificly a laptop. Some of the Chinese 64-bit ARM boards have multiple network ports, mini-PCI, built in Ethernet switches -- these are intended as the guts for a router (some can also be used as WiFi access points).

I just install amanda-client and that created the systemd service files, which
I presumed was how things were supposed to work now.
I guess I will install xinetd and go from there instead.

[CentOS] Software gone AWOL...
I am moving from a CentOS 6 VM to a CentOS 7 VM and two pieces of software I use seem to be missing: RT (from Best Practical Solutions) -- an RPM for rt 3.1.13 was in EPel 6 and until recently, was also in EPel 7. It is not there now. Since it is just Perl code, I wonder if I can just install the el6 rpm on a CentOS 7 system. Bugzilla -- I installed this from an RPM on my CentOS 6 server (bugzilla-3.4.14-2.el6.noarch). It is not in the EPel 7. It too is noarch (also Perl code) and wonder if I can just install the el6 rpm (if I can find it somewhere -- a yum search bugzill finds it, but it is not actually there in the repo. Are there other solutions? (Installing RT "from source" is something of a bear, since there are lots of Perl module dependencies, that I would rather yum deal with if possible.) -- Robert Heller -- 978-544-6933 Cell: 413-658-7953 GV: 978-633-5364 Deepwoods Software-- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

LaTeX Beamer package will do much of that, I don't believe it will handle either videos or music, but without anysort of point and click or drag and drop GUI -- LaTeX Beamer is strictly CLI-based (well there might be GUI frontends out there for LaTeX, but I doubt anything specific for Beamer, and likely not partitularly like what you seem to be asking for). What you are describing *IS* what LibreOffice's Impress does. In the mess-windows and MacOSX world, this nitch is covered by PowerPoint (pretty much to the exclusion of any other tools, except maybe some high-end [expensive] tools) and in the Linux world, Impress covers this nitch (again pretty much to the exclusion of any other tools). Quoting from the Highlander: "There Can Be Only One". So if you are excluding Impress and similar PowerPoint-like software, you are pretty much left with no options (as you seem to have already discovered). Note: *I* have never used any MS-Windows software (including PowerPoint) and personally don't have much use for any of the LibreOffice package (I only use them from their laughable "CLI" interface [eg with the silly --headless option, that only works when the DISPLAY env var is actually bound to a X11 display, which needs to be there, to not use] to convert mess-word and excel files to PDF). > > Thank you. > > ___ > CentOS mailing list > CentOS@centos.org > https://lists.centos.org/mailman/listinfo/centos > > -- Robert Heller -- 978-544-6933 Deepwoods Software-- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] CentOS 6 SELinux question: inbound ssh.
OK, after beating my head against the wall for an hour or so, I finally figured out why I could not ssh from a MacMini (running MacOSX 10.11.6) to my Linux Desktop (running CentOS 6), using the amandabackup account with public key authentification. SELinux! It seems the SELinux won't allow this if the target user's "home" directory is does not have a _home_t security context. It there some trick/hack to fix this *specifically* for the amandabackup account? Right now the amandabackup $HOME is /var/lib/amanda/ and its security context is system_u:object_r:amanda_var_lib_t:s0 It of course needs to retain this for amanda to work. But I need to do something non-standard: I am not able to build a *working* version of the amanda client on the Mac. Despite what it says on the amanda.org website, Amanda is basically not supported under BSD (MacOSX is basically BSD) and I am not getting help on the Amanda mailing lists. I need to backup this machine, so I am going to punt and resurect a script I was using before I started using Amanda and do an independent backup process, but I want to put the backups on the same disk that amandabackup is using and the disk is set up to be written by amandabackup, so I want to use the amandabackup to write the files, using ssh from the amanda account on the Mac. Is there some hack to get SELinux to cooperate with this scheme? Or do I have to do something else? -- Robert Heller -- 978-544-6933 Deepwoods Software-- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

This I believe is > an old instruction and was based on the fact that the kernel needed access > to these partitions before RAID access was available. Actually *grub* needs access to /boot to load the kernel. I don't believe that grub can access (software) RAID filesystems. RAID1 is effectively an exception because it is just a mirror set and grub can [RO] access any one of the mirror set elements as a standalone disk. Note that UEFI partitions can't be RAID at all (and are FAT filesystems) and need to be accessable by the BIOS / boot EEPROM. Once the kernel starts, the raid array(s) can be started, then LVM volumes can be scanned for and set up, then the root file system mounted, and then the system is up and running -- all of that magic is handled in the initramfs. So the rule of thumb is a "small" /boot/efi FAT file system (if using UEFI boot) a /boot mirror set, and the rest whatever RAID logic, probably with LVM on top of that. Usually one creates a UEFI partition on both (or all three or more) disks -- they can't be a mirror set, but certainly can be rsync'ed regularly. Then a smallish mirror set for /boot, than whatever is left used for the main system filesystem: RAID whatever, etc. > > I'm sure someone more knowledgeable will be able to say whether this is > still required.

And I wonder if the EL7 kernel will even show up as an available kernel. EL7 uses Grub 2 and EL6 uses Grub [1]. *Different* config files. Because (unlike Lilo), grub is not updated in the MBR each time its config is updated (eg installing a new kernel), it is very likely the EL7 kernel rpm install might not touch /boot/grub/grub.conf, since it is expecting to update /boot/grub/grub.cfg instead. I know that when I installed Ubuntu 18.04 as a *second* OS, that even though the /boot file system is shared between CentOS 6 and Ubuntu 18.04 the Ubuntu 18.04 installer did not touch /boot/grub/grub.conf and installed /boot/grub/grub.cfg along side (I manually reinstalled grub 1 and manually hacked /boot/grub/grub.conf to put the Ubuntu 18.04 boot option in). > > > > > > Thanks. > > _______ > > CentOS mailing list > > CentOS@centos.org > > https://lists.centos.org/mailman/listinfo/centos > > > > -- Robert Heller -- 978-544-6933 Deepwoods Software-- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

However, I am not inclined to do so. It is not a debian specific problem. It is a Gnome3 / nautilus issue. The Gnome3 devs have basically decided that nautilus should not be in the business of launching applications. So the use of desktop shortcuts to run applications is depreciated / discurraged with gnome3. The problem also exists for CentOS 7.

[CentOS] "Untrusted application launcher (desktop launchers)"

You have two options: If you have mimedefang installed and using it run spamassassin over all incoming messages, you can change mimedefang's default spamassassin filter interface from merely tagging messages to actually rejecting them -- mimedefang can return a code to tell Postfix to boot the spam message with a 5xx status. Or you can have a recipe in .procmailrc to file (or otherwise) messages tagged as spam. (Another thing you can do is configure Postfix's access and client.cidr files to refuse to even talk to various hosts that are known spam sources -- pretty much all of China, Vietnam, Russia (and former USSR countries), and Brazil as well as all of the "silly" TLDs: .science, .stream, .store, .webcam, .acountant, .life, .today, and many more.) > > I've documented the whole configuration here: > > * https://blog.microlinux.fr/spamassassin-centos/ > > The problem with this setup is that spam mail is still delivered, and I > need Thunderbird's filters to weed out incoming mail.

I went from VMS on a VT to a VAXStation 2000 to a VAXStation 3000, to DECStation 5000, to Linux, with some time spent on CP/M-68K and OS-9/68000, as well as SunOS, IRIX, etc. *I* have never owned a machine running any verison of MS-Windows (I did have a box that dual booted MS-DOS and Linux). > > Valeri > -- Robert Heller -- 978-544-6933 Deepwoods Software-- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

I one of the few (?) people who use "none of the above" (meaning all of the "modern" desktop managers). I use fvwm in MWM mode and have a Tcl/Tk coded "menu manager" program.

I am not sure if I really agree with that... I ended up using a thumb drive,
but needed to resort to using the shell to get the disk set up the way I
wanted. *I* don't like GUI installers, since they generally impose limits on
how to install the system.

Re: [CentOS] Failed to get to installer for CentOS 7 VM under CentOS 6...
I just tried a CentOS 7 install to a laptop over PXE and it failed in just the
same way as for the VM.
So, is it not possible to install CentOS 7 via PXE? Or is there something
missing? I just copied the images under os/x86_64/images/ to the tftpd
directory (/var/lib/tftpboot/) and included in
/var/lib/tftpboot/pxelinux.cfg/default this section:
label centos75-64
MENU LABEL CentOS 7.5 x86_64
kernel centos75x86_64vmlinuz
append initrd=centos75x86_64initrd.img
Do I need anything more?
Things seem to die/fail at some point after initializing the graphics frame
buffer. Is there a way to do a non-graphical install? I have a keyboard and
really know how to use it and don't need some silly ("friendly"?) GUI to
install Linux (I don't need hand-holding).

It does not allow for other E-Mail methodologies, including using local UNIX utilies (eg mail or pine or mh or other tools like QWK). I have uninstalled cyrus-imapd and installed dovecot instead.

Re: [CentOS] Convert from LVM
Do you mean you have a CentOS 7 VM which has partitioned is virtual disk (eg /dev/vda) to have a LVM partition, which in turn has a logical volume for root? It should be possible create a fresh virtual disk, add it to the VM as /dev/vdb (say), and then inside the CentOS 7 VM, partition the new disk into however many partitions you need (say /dev/vdb1 for /boot, /dev/vdb2 for swap, and /dev/vdb3 for /) and then use dd or use mkfs and rsync, etc. to copy the file systems, go a grub-install on /dev/vdb and then stop the VM and remove the /dev/vda disk from it and restart it. Oh, you might need to make sure the UUID or LABEL used to reference the root file system in the grub config file is updated to reflect the new root (might not be needed if you used dd). Unlike MS-Windows, Linux is (generally) perfectly happy to disk "transplants", so long as you are careful about re-installing grub and making sure the grub config has the right "magic".

OK, I think at this point it is not wanting to even boot the old disk in EFI mode. Maybe because the old disk is no longer in SATA port 0 (/dev/sda).

And at this point, it will only boot in legacy mode off the old disk. I am considering making a boot ISO, either for a thumb drive or a DVD and booting the machine that way.

Re: [CentOS] CentOS6: HELP! EFI boot fails after replacing disks...
OK, one other tidbit: The EFI BIOS has a UUID in its boot options. I expect that this identifies the old system disk, but I don't know where that UUID comes from. It is NOT the VFAT UUID for the EFI partition and is not any of the UUIDs for any of the Linux file systems or RAID arrays, or really anything else I can find under Linux. I'm guessing it is something the EFI BIOS has come up with, but I am not sure what exactly. *I* don't remember filling that in -- I think anaconda filled it in during the install process, so presumably, there is some magic under Linux to get this UUID (for the new disk(s)) and fill it in, but I cannot figure out what. Maybe efibootmgr has something to do with it, but efibootmgr does not work, either on a live system or a system booted from a DVD (CentOS 6.9 boot/install DVD) -- efibootmgr wants a kernel module named efivars that does not seem to exist.

[CentOS] CentOS6: HELP! EFI boot fails after replacing disks...
OK, I wanted to replace the 500G disks in a Dell T20 server with new 2TB disks. The machine has 4 SATA ports, one used for the optical disk and three for the hard drives. It is set up with /dev/sda and /dev/sdb with each three partitions: 1 -- VFAT (for EFI) 2 -- ext4 (for /boot) 3 -- LVM /dev/sda2 and /dev/sdb2 are a mirror raid (/dev/md0) /dev/sda3 and /dev/sdb3 are a mirror raid (/dev/md1), with LVM on top of that. /dev/sdc is a disk containing one file system and mostly used by AMANDA for backup (it has a "virtual" tape changer). This morning I shut the machine down and pulled [the 500G] /dev/sdb and installed a new 2TB disk as a new /dev/sdb. Partitioned it (with parted) to be much like /dev/sda (except partition 3 is way bigger). I added the new /dev/sdb2 to /dev/sda2 (boot raid set) and dd'ed /dev/sda1 to /dev/sdb1. I then created a new RAID set (degraded) with /dev/sdb3, used pvcreate on it, used vgextend to add it to the system volume group, then used pvmove to move the extents from the old disk to the new disk. Meanwhile I partitioned a second 2TB disk using a USB SATA dock and copied the old 500G /dev/sdc1 to the new 2TB disk. So far so good. Then I shut the machine down, swapped in the new backup [2TB] disk and pulled the old system [500G] disk and installed the third new [2TB] disk. The system won't boot that way. It seems there is something in the UEFI (secure boot) logic that wants the original disk, even if everything is moved over. I ended up putting the original /dev/sda in. The machine boots and is using the new system disk (a raid array in degraded mode). What is the magic to fix this? I tried to run efibootmgr, but it wants a model named efivars loaded, but there is no such module available.

[CentOS] Mailing list config question / minor rant
The centos@centos.org seems to be *uniquely* configured to hold messages with a (single) CC to self. ALL of the other mailing lists I am on have no problem with a CC to self. My mailer software is configured to CC to myself. This is *only* a problem with the CentOS list. Why is this?

[CentOS] Question about "generic" USB <=> Serial Port kernel drivers...
OK, I am running CentOS 6 on my Laptop and Desktop, presently kernel version 2.6.32-696.20.1.el6.x86_64 (yes, a version or so out of date -- I'll probably do an update soon -- non-trivial since my Internet connection is via dialup). I recently bought a couple of Adafruit Arduino compatibles, a Flora and a Metro 328. Hooking up the Flora and the Metro to a Raspberry Pi running Raspbian (kernel 4.9.35-v7+), tells me that the Metro 328's USB uses a FTDI USB serial interface (ftdi_sio.ko) and the Flora uses the cdc_acm (cdc-acm.ko) USB serial interface. Both of these drivers are available with CentOS 6's kernel, but since Adafruit uses their own Vendor & Product IDs and my (old) kernel's ftdi_sio and cdc-acm drivers don't have Adafruit Vendor & Product IDs, the drivers don't automagically connect. The ftdi_sio has parameters for the Vendor & Product IDs, and specifing the product ID for the Metro 328 allows the driver to latch onto the Metro 328's USB connect and things work (I get a /dev/ttyUSB0 device). The cdc-acm does not have any parameters and I don't see any way to get it to connect. I am pretty sure all Adafruit did was change the programming of the USB chip to have their Vendor & Product IDs and the driver should work (the FTDI one does, once the Vendor & Product IDs are passed to it). My question: since the cdc-acm is not parameterized, I am guessing I need to get the kernel module source (from RH's kernel source RPM? Or maybe Elrepo has it?), hack in the Adafruit Vendor & Product IDs into its table of Vendor & Product IDs and recompile it. Is this correct? Also: is there some "trick" that allows me to create a kernel module that will work with kernel updates, without having to re-compile it after every kernel update? -- Robert Heller -- 978-544-6933 Deepwoods Software-- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

[CentOS] CentOS 6.8, Iptables 1.4.7, and MASQUERADE
I have a server that is also a firewall router at a public library with a fiber optic Internet connection. It is running kernel 2.6.32-642.4.2.el6.x86_64 (current CentOS 6.8) and Iptables 1.4.7 (current stock CentOS 6.8). I having trouble with Internet throughput. I am supposed to be getting 20Mbits down and 20MBits up, but I am not getting that. It has no problem doing 20MBits down, but for uploads of *large* files (using different protocols, such as ssh or http), the upload starts at 20MBits, but over time quickly slows down to about 3MBits. Speedtests claim I am getting about 20/20. I seem to be about to get 3Mbits *per transfer*, even if the transfers are concurrent and MRTG shows total throughput edging up to 6Mbits. What can possibly be going on. My ISP is not believing there is anything wrong on their end. About the only thing left is maybe some sort of weirdness with Iptables imposing some sort of I/O overhead, maybe related to the MASQUERADE postrouting.

[CentOS] Verifing: CentOS 5 cannot resize a *live* root filesystem
Just want to verify: CentOS 5's FS utilities are too old to safely resize a *live* (mounted, etc.) root file system (and the CentOS 5 installer/rescue system does not include either resize2fs or fsadm utilities). I am presuming I will need a full-fledged Live CD/DVD to resize the root file system. This is for an old 32-bit laptop that presently has CentOS 5.11 on it -- I want to shrink the root file system (it is LVM) and make a separate /home file system, then upgrade it to something newer (not C6, since it is not PAE -- I'm *hoping* Ubuntu's 32-bit installer can deal with a non-PAE 32-bit system). -- Robert Heller -- 978-544-6933 Deepwoods Software-- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] USB Serial ports (ttyACMn) CentOS 6.7 (64-bit) vs. CentOS 6.7 (64-bit)
I sent this out about a week or so ago, but I have heard nothing. I am *thinking* it is a SELINUX problem, but I cannot figure out what. The SELINUX settings for both machines are *exactly* the same (the stock defaults for a standard CentOS 6 install). The *only* difference is that the desktop (sauron) has a few VMs setup (under KVM) and the laptop (gollum) does not. The desktop has an AMD processor and a nVidia video chipset and the laptop has an Intel processor and an Intel graphic controller. Although I can't see how either the processor or video chipset would have anything to to with the USB or USB serial port-type devices. The desktop also has a PCI quad serial port card and includes the 8250.nr_uarts=8 kernel option and is set up to use an analog dialup modem to make PPP connections (again, I don't see that as having anything to do with anything).

OK, I tried rebooting without the '8250.nr_uarts=8' option and that had no effect. I wonder if I should file a bug report? I don't know if I should file it with the Red Hat bugzilla or the CentOS bugzilla. > > Both machines are running the same kernel: 2.6.32-573.12.1.el6.x86_64 > > > > > At Thu, 4 Feb 2016 16:13:33 -0500 Robert Heller <hel...@deepsoft.com> wrote: > > > > > I have two computers: both running CentOS 6.7, 64-bit, with > > kernel 2.6.32-573.12.1.el6.x86_64.

[CentOS] USB Serial ports (ttyACMn) CentOS 6.7 (64-bit) vs. CentOS 6.7 (64-bit)
I have two computers: both running CentOS 6.7, 64-bit, with kernel 2.6.32-573.12.1.el6.x86_64. One is a laptop with an 2 core Intel processor and the other is a desktop machine with a 4 core AMD processor. Both with selinux enabled. I have a USB serial port device (a RR-CirKits LCC-Buffer USB).

VESA defined modes are
- 320Ã200
- 640Ã400
- 640Ã480
- 800Ã600
- 1024Ã768
- 1280Ã1024
No idea whether the vesa driver supports non-vesa modes, but did you try using
nouveau instead of vesa?
/var/log/Xorg.0.log will tell you the servers opinion on what you added to your
config.

[CentOS] New monitor weirdnesses (CentOS 5.11)
I just got a new monitor for my desktop system (the old one died after *many* years of service). The new monitor is a high res 16:9 monitor, but the VESA video driver insists on using 1024x768 (which was the resolution of the *old* monitor). It does seem to detect higher, 16:9 resolutions but it is not using them. I *think* I need to set some low-level video mode thing, but it has been a long time since I have had to do that that I have totally forgotten how to do it. And I have been unable to find it with a websearch either. >From /var/log/Xorg.0.log: (II) VESA(0): Printing DDC gathered Modelines: (II) VESA(0): Modeline "1366x768"x0.0 85.50 1366 1436 1579 1792 768 771 774 798 +hsync +vsync (47.7 kHz) (II) VESA(0): Modeline "1360x768"x0.0 85.50 1360 1424 1536 1792 768 771 777 795 +hsync +vsync (47.7 kHz) (II) VESA(0): Modeline "800x600"x0.0 40.00 800 840 968 1056 600 601 605 628 +hsync +vsync (37.9 kHz) (II) VESA(0): Modeline "800x600"x0.0 36.00 800 824 896 1024 600 601 603 625 +hsync +vsync (35.2 kHz) (II) VESA(0): Modeline "640x480"x0.0 31.50 640 656 720 840 480 481 484 500 -hsync -vsync (37.5 kHz) (II) VESA(0): Modeline "640x480"x0.0 31.50 640 664 704 832 480 489 492 520 -hsync -vsync (37.9 kHz) (II) VESA(0): Modeline "640x480"x0.0 30.24 640 704 768 864 480 483 486 525 -hsync -vsync (35.0 kHz) (II) VESA(0): Modeline "640x480"x0.0 25.18 640 656 752 800 480 490 492 525 -hsync -vsync (31.5 kHz) (II) VESA(0): Modeline "720x400"x0.0 28.32 720 738 846 900 400 412 414 449 -hsync +vsync (31.5 kHz) (II) VESA(0): Modeline "1024x768"x0.0 78.75 1024 1040 1136 1312 768 769 772 800 +hsync +vsync (60.0 kHz) (II) VESA(0): Modeline "1024x768"x0.0 75.00 1024 1048 1184 1328 768 771 777 806 -hsync -vsync (56.5 kHz) (II) VESA(0): Modeline "1024x768"x0.0 65.00 1024 1048 1184 1344 768 771 777 806 -hsync -vsync (48.4 kHz) (II) VESA(0): Modeline "832x624"x0.0 57.28 832 864 928 1152 624 625 628 667 -hsync -vsync (49.7 kHz) (II) VESA(0): Modeline "800x600"x0.0 49.50 800 816 896 1056 600 601 604 625 +hsync +vsync (46.9 kHz) (II) VESA(0): Modeline "800x600"x0.0 50.00 800 856 976 1040 600 637 643 666 +hsync +vsync (48.1 kHz) (II) VESA(0): Modeline "1280x720"x60.0 74.48 1280 1336 1472 1664 720 721 724 746 -hsync +vsync (44.8 kHz) (II) VESA(0): Searching for matching VESA mode(s): Any of 1360x768, 1366x768, or 1280x720 would be fine. Following this are a pile of blocks starting with 'Mode: ...' or '*Mode: ...'. I think these are the modes the driver is reading from some 'magic' place and maybe the stared ones are 'matches' to the DCC mode lines. I think what I need to do is update this 'magic' place with a low-level program (probably eventually run in /etc/rc.local or someplace like that) that will add in a 'Mode' -- I did this *years* ago with little machines with Intel video chips and 16:9 monitors. But I am totally blanking on the command to use. I find using a 4:3 video mode on a 16:9 monitor somewhat unusable. I running CentOS 5.11 w/Xen. The video chipset is a NVIDIA Corporation C77 [GeForce 8200] (rev a2). I am using stock CentOS 5 drivers and libraries (slightly out of date). -- Robert Heller -- 978-544-6933 Deepwoods Software-- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

The most common case is that the machine implementing the gateway/routing/firewall is also being used for other stuff.

First, it's a nested mount: file system A on /, and file system B on /boot, and file system C on /boot/efi. Therefore the mount process must make sure they're mounted in that order, or there's failure. I've never once had a problem with nested mounts. Is this a problem people have? First I've heard of it. 'mount -av' has *long* supported nested mounts. Nested mounts are a 'trick' from the days of UNIX from way back when. Mount knows all about going through /etc/fatab and coming up with a sane and correct order for mounting file systems. Second, there is no good reason for the EFI System partition to ever be mounted; and multiple reasons to not ever mount it (Windows and OS X never mount the EFI System partition but somehow all the Linux distros are obsessed with mounting things that don't need mounting). Eventually systemd will become smarter and handle on-demand dynamic mount and umount, including the ESP so this will get better but even better would be not ever mounting it in the first place. It would be nice if that were the case, however, in an automated dual-boot system with EFI, we have to manage rEFInd *somewhere*, and it is easier for us to manage it under configuration management in Linux than in Windows. Our managed dual-boot workstations need to be able to reboot into the other OS during the evening for updates. -- Robert Heller -- 978-544-6933 Deepwoods Software-- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I get tired of googling every-time I have to do something I don't remember how to do regarding LVM, so I usually just don't bother with it at all. I believe it has some benefit for my use cases, but I've been reticent to use it, since the last time I got LVM problems, I lost everything on the volume, and had to restore from backups anyway. I suspect I shot myself in the foot, but I still don't know for sure. At the risk of some ridicule I suggest that you look at installing Webmin. It is a web based system administration tool that I find invaluable. The two most common complaints I encounter when I discuss its merits are 'security' and 'transparency'. The security issue is trivially dealt with. Install Webmin and configure it to listen on 127.0.0.1 using its standard port TCP1. Install Firefox on the same host and then run firefox from an 'ssh -Y' session using the --noremote option. If you are totally paranoid then firewall TCP1 as well, configure Webmin to use https only, and then only start the webmin service when you are performing maintenance. There are less draconian measures that are in my opinion equally secure from a practical standpoint but I am sure that you can figure those out on your own. The transparency issue is really unanswerable. There exists a school of thought that if you are going to administer a Linux system (or OS of the proponent's choice) then you should learn the command syntax of every command that you are called upon to use. This is the one-and-only path to enlightenment. Like upholding motherhood and promoting the wholesomeness of apple-pie this sort of moralizing really brooks no answer. You can guess my opinion on that line of puritanism. HA! You only really need to learn *one* command: the man command. The man provides 'enlightenment' for all other commands: man vgdisplay man lvdisplay man lvcreate man lvextend man lvresize man lvreduce man lvremove man e2fsck man resize2fs These are the only LVM commands I use regularly (yes there a a pile more, but most are rarely used and a handful only used in startup/shutdown scripts or when rescuing) and I often end up use the man command to refresh my memory of the command options. As you have painfully discovered, infrequently used utilities and commands are difficult to deal with. The process of learning, or relearning, the correct arcana is particularly noisome given the notorious inconsistency of syntaxes across different utilities and the spotty coverage of up-to-date documentation. Google can be a dangerous guide given the wide variation of practice across differing flavours of *nix and the widespread aversion to providing dates on writings. In consequence I consign transparency arguments and their proponents to the religious fanatic file. Nothing personal but there is no point in arguing belief systems. Right, expecting a *web search* to give *correct* command documentation is problematical. Using the local system man pages often works better, since the man pages installed with the installed utilities will cover the *installed* version and not the version that might be installed on a *different* distro, etc. If you want to get infrequently performed sysadmin tasks done reliably and with a minimum of fuss use something like Webmin and get on with the rest of your life. -- Robert Heller -- 978-544-6933 Deepwoods Software-- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
