[CentOS] File Permissions or Partition Write/Read for everyone
Hello all, I am kinda new to Linux, FreeBSD...most Windows user, anyway. I got a little problem here maybe you can help me solve it. I just bought a new 500Gb HDD which i formated using ext3 under Centos 5, my plan was to use it under FreeNAS as another Backup File Disk(It has already like 400gb of data), when I try to access the disk via samba/cifs I just have the read attribute or permission, how can i change the whole partition permission rights to be accessible to write/read for everyone? (I will mantain the security using samba users and groups of course.), or do I have to apply the chmod comand to the main folder? I'm really stuck here. Thank you Victor. P.S. Sorry for my english. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

"man find" is one of the most hideous manual pages on a linux system (man tar comes close) - so a bit help from your side would have been nice. a) use locate whereever you can b) find / -type f-name "kernel*.rpm" -- this recursively (from / downwards) finds file which begin with "kernel" and end with "rpm" c) This is not needed anyway, as those packages are ALREADY installed.

Create a directory, and mount the partition onto it. The rw permission for everyone is chmod -R 777 /mountpoint This, however, is a very bad practice. The proper one is to give permission to the intended user/group only, and double enforce it with samba. -- Fajar Priyanto | Reg'd Linux User #327841 | Linux tutorial http://linux2.arinet.org 15:09:24 up 35 min, 2.6.22-14-generic GNU/Linux Let's use OpenOffice. http://www.openoffice.org The real challenge of teaching is getting your students motivated to learn. signature.asc Description: This is a digitally signed message part. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] centOS xen domU kernel
Hi, how can i make actual xen kernel to work under my domU virtual machines? When i will provide as kernel /boot/vmlinuz-2.6.18-53.1.14.el5xen as ramdisk /boot/initrd-2.6.18-53.1.14.el5xen.img , it will not work becouse of error that root device does not exists. And when it is booting it is showing that raid md0 and my logical volumes does not exists - like those on dom0. I believe it is becouse of ram disk. What is the best approach to solve this .. in official way? Can i use same ramdisk as for dom0, how? or should i create a new one for xen ...

It is a fedora 7 box which is responsible for internal dns and samba / backup so having it set this way has been kinda handy as i have tested the newer kernels on another similar but not as important box before altering the default in grub.conf. This bit of knowledge is *very* useful for me at the present time as i have 2 CentOS 5.1 boxen (identical dell 2950s, dual quadcores, large raid 6 yadda yadda) one of which is in production for an electronic patient record for the NHS, the other for backup and testing of updates. /me firing up vi /etc/sysconfig/kernel cheers mike ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Yum + priorities plugin question
Hello all! I've recently started using the priorities plugin as part of my best practices. It's very effective, and prevents nasty things from happening (like atrpms upgrading python and disabling yum.) I'm wondering if there's a simple and elegant way to allow package-name-based exclusions. For example: For my mysql cluster, I'd prefer to have the latest mysql and mysql-server packages which I can get from utterramblings (Thanks Jason!), however, to do so while using the priorities plugin, I'd need to make that repo an equal priority with base, so that it'll upgrade. I've worked around the problem by creating a duplicate repo with the exceptions as an includepkg and a priority equal to that of base, but it seems less than elegant, and I know it results in double the internet traffic for the repo mirror, which is less than friendly. Does anyone know if there's a more elegant way to deal with this issue, or might this be an appropriate feature request for the plugin developer?

You should be seeing something like "booting CentOS in x seconds". You can interrupt this by pressing a key. You should then see all three options and the first one with CentOS (2.6.18- 53.1.14.el5) highlighted. If you continue with that I don't see a way it could not be booting into vmlinuz-2.6.18-53.1.14.el5. What makes me wonder a bit is this: (hd0,2).

Sorry I don't have the answer off hand, but it might be as simple as increasing the level of verbosity. Another option is the 'arp' command, at least if the host is on the same network.

[CentOS] cups causing segfault
Everyone, I have a new installation of Centos 5.1 that I am using on a gateway server that also has dhcp, named servers. I also have cups set up to function as a print server, and sendmail is being used as a relay to our mail server. yum-cron appears to be updating everything daily as desired. This Centos 5.1 gateway was created to replace a Fedora Core 5 system with the same functions. When I set up cups I copied the FC5 subdirectory into the Centos 5.1 system. Everything appears to work as expected. For some reason I am having sendmail crator without giving me a notice in the logs as far as I can determine. However, when I looked at the messages logs I found it filled with many entries in the form of : kernel: ipp[24519]: segfault at rip 2bf2abc0 rsp 7fff25495348 error 4 I've done a google search and there appeared to be a problem with doubled printer entries in the printer.conf causing the log entry, but after checking my printer.conf file everything appears to be ok. This file also worked on FC5 without a problem. I am not sure if the cups problem is related to the sendmail problem. Any ideas?

Re: [CentOS] Is it possible to lvrename the current root partition?
On May 2, 2008, at 17:24, Ross S. W. Walker wrote: Sure you can do all this from rescue mode off the first CD. Boot the cd type in 'linux rescue' and continue to the command prompt. First, thanks for the detailed list, Ross. It was very helpful. I was able to rename both the VG and the LVs, but it was slightly more complicated than the items on the list. 1) make sure swap isn't using the swap lv - swapoff -a What I did was say "Skip" when the rescue image asks you if you want it to find existing Linux installations and mount them under /mnt/ sysimage. The reason I did this was that if you let it mount your partitions, you need to go through a lot of additional steps to get everything under /mnt/sysimage unmounted, and nothing in there is needed to do the rename (unless you want to rename the VG -- see below). 2) unmount all lvs mounted - umount /mnt/sysimage/boot - umount /mnt/sysimage Not needed because of what I did in step 1, but there are additional mount points to unmount if you do let the rescue image do the mounts (do a "mount | grep sysimage" to find all the mount points). 3) mark all lvs as unavailable - lvchange -a n This step is indeed required unless you chose to skip the mounting of /mnt/sysimage altogether. Do a "lvm lvscan" to find out which LVs are active (and use "lvm lvchange" as described below). 4) rename the volume group - vgrename Well, vgrename is not part of the rescue disk. So if you want to do this, you will have to mark the root LV as available, mount it, and then copy /mnt//usr/sbin/vgrename to /tmp. Then you have to unmount the root partition and mark the LV as unavailable. 5) rename the logical volumes - lvrename \ 6) repeat #5 as necessary The lvrename binary (symbolic link) does not exit in rescue mode, so you will have to type "lvm lvrename" (and "lvm lvchange", etc.). Also, you have to use a forward slash here. 7) re-activate all the lvs - lvchange -a y Remember to use the new names. 8) re-mount the root and boot lvs, - mount /dev// /mnt/sysimage - mount /dev// /mnt/sysimage/boot I think this part worked as is. 9) chroot to the mounts with, 'chroot /mnt/sysimage /bin/bash' Before I could do this, I had to use mknod to create the device entries in /mnt/sysimage/dev/mapper/- and the symbolic links in /mnt/sysimage/dev//. Make sure the symbolic links point to /dev/mapper/... and not /mnt/sysimage/dev/ mapper/... I don't remember if this was required to mount it while in rescue mode or to make the system bootable again. But I remember that I had to do it. 10) edit /etc/fstab 11) edit /boot/grub/grub.conf 12) remake the initrd - mkinitrd -f /boot/initrd-$(uname -r).img $(uname -r) You will have to type the release version of the kernel instead of relying on the output of uname -r. It turns out that I can skip steps 7-12 since I plan to upgrade the systems from CentOS 4.6 to CentOS 5.1 immediately after doing the rename, and the installer (anaconda) will take care of all these details. I just had to adjust my kickstart scripts to use the new names. Anyway, thanks again for all the help. I'm starting to upgrade my two dozen or so desktops to CentOS 5.1 using the new VG and LV names.

You either boot with the Windows Boot-Manager (which looks different from the CentOS one, so you should be able to easily see that) or with some Grub on *another* partition (not the boot partition on hd(0,2) which is the third partition on disk 1). In which order where the systems installed? Did you run into any trouble after installing the second one concerning the dual-boot scenario? Try to reminisce about the history of the system and what got installed when and how. And if you reinstalled grub (or fixed the Windows boot manager with fixmbr from the Windows recovery console) some time later for instance (and then to the wrong partition). That is the clue to understanding why it is different to your other systems. The Windows boot menu is called "boot.ini" and is in the root drive of the Windows installation (it's hidden in Windows). If that doesn't contain any mention of your CentOS, then try to mount the other unmounted partitions one by one and check which holds the other /boot partition.

Kai: I am not using Windows Boot Manager. Grub comes up, as on the 2 boxes, where things are working properly. Questions: (a) Can I copy /boot/grub/grub.conf on my box and replace that file on my wife's box, with my version? Would that work OK? Worth a try? (b) Which files should I compare, between my box and my wife's box, the problematic one, to see if I can locate differences? There was confusion on my part, when I installed Windows XP on my wife's box. Hers was the first one I installed Win XP on, which I'd never installed before and it ended up getting installed more than once. However, in general, I thought her box was the easiest, with regard to the WinXP installations. There may have been some partitioning issues also, since each box has 4 partitions on the Windows side (C, D, E & F). In general, it is *much* easier for me to install CentOS than to install Windoze. And, *much* faster. :-) TIA, Lanny ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] R (statistics package) on CentOS-5 ?
On Wed, 7 May 2008 at 9:57pm, Kay Diederichs wrote the statistics package R (www.r-project.org) was available for CentOS-4, but I need it for CentOS-5 (64bit). RPMforge has R-2.5.1 for CentOS-4, so I thought I'd try to install that on CentOS-5. However, yum complains about missing ggv, and the specfile indeed says that R requires ggv, which is not in CentOS-5 (it has kghostview). I could probably install with "rpm -Uvh --nodeps", but the question is rather: has anybody built R for CentOS-5 ?

The best way to learn to use find is to play with it. I have aliases and functions that use it for many, many purposes, especially for finding things in source code files. I strongly suggest that you take the time to wade through the man page. Find is a very powerful command, and even if the man page is poorly laid out, there is a lot you can do with it. For this purpose, what you probably would need to do is this (asoot): find / -name "kernel*.rpm" It may take a while, but it will absolutely find every kernel-related rpm on your system.

If the destination MAC were to be encoded in the packet, no switches would be able to keep their internal tables sane, as it would be flooded with MACs, all on the same port (the one connected to the gateway). When a switch recieves a packet adressed to a MAC that doesn't appear in the switch-internal list, the packet will be flooded (sent out on all ports). Once a packet from that MAC passes through the switch, that MAC will be added to the list, and future packets only leave that one port.

The locate db is skipping only /tmp I think. It makes use of an index, that's why it's so fast. updatedb is run by cron.daily to update the db. If you get something in in-between it won't be able to find it, of course. In such a case you run it manually. Then "locate whatever". Note, that locate doesn't know any wildcards, you can only search for literals. For searching for your kernel rpms you could either use locate kernel (which will find a lot ...) locate .rpm (which will find all rpm files, which is much less) and then: locate .rpm|grep kernel /var/cache/yum/updates/packages/kernel-headers-2.6.18-53.1.14.el5.i386.rpm /var/cache/yum/updates/packages/kernel-xen-2.6.18-53.1.14.el5.i686.rpm /var/cache/yum/updates/packages/kernel-xen-devel-2.6.18- 53.1.14.el5.i686.rpm > > All else aside, I can't count the number of times I've had my head > handed to me right here on this list for failing to look something up > before asking about it.

Another way that I prefer is sfdisk -l It's output can be saved in a file and it can even make copies of things (like partition tables) that can be fed back into it to recreate a disk if the info gets wiped.
