selinux allow FTP
by Tim Dunphy 05 Mar '15

05 Mar '15

Hey folks, How would I allow a user to connect to an FTP server, upload and download files and delete files as well, if that server is in enforcing mode for SELinux? I'm using proftpd 1.3.5 on CentOS 7. Thank you! Tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B

Extdata / Extprograms Plugins for Dovecot Pigeonhole?
by E.B. 04 Mar '15

04 Mar '15

Hello, I want to install Dovecot Pigeonhole and use the Extdata and Extprograms plugins. According to the dovecot documentation[1,2], those plugins need to be compiled. So two questions: * Are either of these plugins built into the Pigeonhole that is available in the CentOS 7 extras repo? * Is it possible to use these plugins with Pigeonhole installed from yum? Does the compilation requirement mean that I have to remove not only Pigeonhole, but also Dovecot itself from my system and build everything by hand? :-( PS - Is there another version of Pigeonhole in a repo elsewhere (like EPEL or DAG?) that might have what I want?

Dovecot Pigeonhole version in extras repo?
by E.B. 04 Mar '15

04 Mar '15

Hi, I want to install Dovecot Pigeonhole from the yum Centos extras repo, but "yum info" reports the version number not of the plugin but of dovecot itself. Can anyone say what the Pigeonhole version is currently for the extras repo for CentOS 7?

Memory issue in kernel sctp implementation
by Danny Smit 04 Mar '15

04 Mar '15

Dear all, I'm running into a possible memory issue with the SCTP implementation in CentOS 6, using lksctp-tools. So far I've not seen the problem with other distributions yet. The problem is that whenever a SCTP client connection is initiated to a second host and port at which no SCTP server application is listening The scenario is simple: - call socket() to create a socket. - call sctp_connectx() to establish a connection. The last call is repeated periodically to retry to establish a connection. When looking on the wire using wireshark it shows that an SCTP INIT packet is sent to the second host, which replies with an SCTP ABORT. This is exactly according to the SCTP specification. However it appears ABORT isn't propagated into to application layer that calls sctp_connectx(). Furthermore, because reconnect attempts are made, a steady memory increasement occurs. Looking at /proc/meminfo, the increasement occurs in SUnreclaim, the kernel slab cache. Can you advice if this can be an issue with the SCTP implementation in the kernel? Maybe an issue solved upstream, but not (yet) backported into centos 6? It applies to the following package versions (also to older kernels): - kernel-2.6.32-504.8.1.el6.x86_64 - lksctp-tools-1.0.10-7.el6.x86_64 Regards, Danny Smit

Ignorant question on SSL certs
by Timothy Murphy 04 Mar '15

04 Mar '15

I'm getting endless complaints about my dovecot cert, /etc/pki/dovecot/certs/dovecot.pem which I created years ago following the dovecot instructions. Do I really have to use a separate cert and key for dovecot? Can I not use the "standard" cert in /etc/pki/tls/certs (and key) from CACert.org ? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

Apologies for the late replies
by m.roth＠5-cent.us 03 Mar '15

03 Mar '15

*sigh* There seems to have been a problem with my hosting provider's mailqueues this morning. As in, I called, and told them, and no one had reported it, and I even got an actual trouble ticket.... <g> So, I'm assuming they just figured it out. I sent the one on the cert, and the other, before 11:00 this morning.... Sorry to post-add to the conversation. mark

disk space trouble on ec2 instance
by Tim Dunphy 03 Mar '15

03 Mar '15

Hey all, Ok, so I've been having some trouble for a while with an EC2 instance running CentOS 5.11 with a disk volume reporting 100% usage. Root is on an EBS volume. So I've tried the whole 'du -sk | sort -nr | head -10' routine all around this volume getting rid of files. At first I was getting rid of about 50MB of files. Yet the volume remains at 100% capacity. Thinking that maybe the OS was just not letting go of the inodes for the files on the disk, I attempted rebooting the instance. After logging in again I did a df -h / on the root volume. And look! Still at 100% capcity used. Grrr.... Ok so I then did a du -h on the /var/www directory, which was mounted on the root volume. And saw that it was gobbling up 190MB of disk space. So then I reasoned that I could create an EBS volume, rsync the data there, blow away the contents of /var/www/* and then mount the EBS volume on the /var/www directory. So I went through that exercise and lo and behold. Still at 100% capacity. Rebooted the instance again. Logged in and.. still at 100% capacity. Here's how the volumes are looking now. [root@ops:~] #df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 9.9G 9.3G 49M 100% / none 312M 0 312M 0% /dev/shm /dev/sdi 148G 116G 25G 83% /backup/tapes /dev/sdh 9.9G 385M 9.0G 5% /backup/tapes/bacula-restores /dev/sdf 9.9G 2.1G 7.4G 22% /var/lib/mysql fuse 256T 0 256T 0% /backup/mysql fuse 256T 0 256T 0% /backup/svn /dev/sdg 197G 377M 187G 1% /var/www There are some really important functions I need this volume to perform that it simply can't because the root volume is at 100% capacity. Like the fact that neither mysql nor my backup program - bacula will even think of starting up and functioning! I'm at a loss to explain how I can delete 190MB worth of data, reboot the instance and still be at 100% usage. I'm at my wits end over this. Can someone please offer some advice on how to solve this problem? Thanks Tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B

Strange crash after NVidia driver installation from ELRepo
by info＠microlinux.fr 03 Mar '15

03 Mar '15

Hi, I just had the weirdest of system crashed. Here goes. I wanted to install a desktop step by step, as I usually do. First the base system, then the X Window System, then the WindowMaker window manager. Everything went OK, then I installed kmod-nvidia from ELRepo. Yum informed me that the driver conflicted with x11-glamor (something like that), so I removed the corresponding package. While doing all this, the system still defaulted to boot in console mode (meaning multi-user.target and not graphical.target). To test X, I just launched WindowMaker using startx. Anyway, I rebooted, and then... nothing. System refused even to startup, and systemd suggested to me that I open journalctl (which taught me nothing). Right now I've started a Slax LiveCD to backup all my data and reinstall the whole thing from scratch. I don't have the slightest clue as to what could possibly have happened here. The only thing I wonder: could it be that installing the kmod-nvidia driver while booting to a default console (and not graphical) could lead to this weirdness? A previous installation on that machine went OK, but the difference was that the first time, I started with a full GNOME installation right away. Any suggestions? Niki

Amanda Testing RPMs
by Johnny Hughes 03 Mar '15

03 Mar '15

It was noted in CentOS Bug 7795 that the amanda package in CentOS does not have dump or xfsdump support: http://bugs.centos.org/view.php?id=7795 I found that it is also like this upstream and they plan to fix it at some point: https://bugzilla.redhat.com/show_bug.cgi?id=1140321 In the mean time, I have created 2 sets of RPMs .. one with dump support and one with dump and xfsdump support: Dump Only: http://people.centos.org/hughesjr/c7-amanda/dump-only/ Dump and XFSDump: http://people.centos.org/hughesjr/c7-amanda/xfs-support/ If we can get some people who actually use amanda to check these files and feedback into the CentOS Bug (7795 link above), we might help the RHEL team with deciding how to compile the fix (with dump only or dump and xfsdump support). Please feedback to the CentOS-Devel mailing list or bug 7795. NOTE: These RPMs should work, but they are not signed and should be considered testing quality at present .. so not production ready without user testing at this point. Thanks, Johnny Hughes

installing C7 on a laptop with Win7, dual boot
by Fred Smith 03 Mar '15

03 Mar '15

Hi all! I've just installed C7 on my netbook that already contained Win7 (and also Fedora 19, which the C7 is intended to replace).

Correct, the grub2-mkconfig command doesn't emit lines about windows, but it puts the above lines into the resulting (grub2/grub.cfg) file - towards the bottom. [You could hand-edit these lines into that file if you want, but having them in the 40_custom file means that they will be included when the grub.cfg file is recreated after a linux kernal update.] When you boot the machine you should see the (windows) "name" entry at the bottom of the list of kernel options. Select it and the machine should boot into windows. Windows does have a couple of partitions -- the main/production bootable one as well as a rescue one. I believe that (hd0,2) is the default location/naming for the production/bootable one. - Richard

X11 fonts question
by Fred Smith 02 Mar '15

02 Mar '15

I'm having trouble figuring out which RPM would contain X11 fonts that go by names containing: "-courier-medium-r-*-18-" "-courier-bold-r-*-18-" "-courier-medium-o-*-18-" in sizes 18 (shown), 14, and 12. so far I can't figure it out. I've looked at the contents of all the xorg-x11-fonts-* packages that "yum list available | grep xorg-x11-fonts" lists. The best I've come up with is a bunch that contain files named "*-courXXXX-*" followed by some uppercase characters whose meaning I don't know (where I show "XXXX" above). Since I seem to be fairly clueless on this topic, I'd welcome any useful advice that any of you can give. thanks! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- Show me your ways, O LORD, teach me your paths; Guide me in your truth and teach me, for you are God my Savior, And my hope is in you all day long. -------------------------- Psalm 25:4-5 (NIV) --------------------------------

NFS and inode64
by m.roth＠5-cent.us 02 Mar '15

02 Mar '15

Well, we got it working. However, the issue we're now worried about is users creating files and subdirectories. Do we need to worry, and if so, is there some way to reserve inodes < 32k table, other than creating tens of thousands of dummy files now? We don't want, a year or two down the road, for this system to be running, and suddenly everything's broken, because all lower inodes have been used.

Looking for a life-save LVM Guru
by Khemara Lyn 02 Mar '15

Dear All, I am in desperate need for LVM data rescue for my server. I have an VG call vg_hosting consisting of 4 PVs each contained in a separate hard drive (/dev/sda1, /dev/sdb1, /dev/sdc1, and /dev/sdd1). And this LV: lv_home was created to use all the space of the 4 PVs. Right now, the third hard drive is damaged; and therefore the third PV (/dev/sdc1) cannot be accessed anymore. I would like to recover whatever left in the other 3 PVs (/dev/sda1, /dev/sdb1, and /dev/sdd1). I have tried with the following: 1. Removing the broken PV: # vgreduce --force vg_hosting /dev/sdc1 Physical volume "/dev/sdc1" still in use # pvmove /dev/sdc1 No extents available for allocation 2. Replacing the broken PV: I was able to create a new PV and restore the VG Config/meta data: # pvcreate --restorefile ... --uuid ... /dev/sdc1 # vgcfgrestore --file ... vg_hosting However, vgchange would give this error: # vgchange -a y device-mapper: resume ioctl on failed: Invalid argument Unable to resume vg_hosting-lv_home (253:4) 0 logical volume(s) in volume group "vg_hosting" now active Could someone help me please??? I'm in dire need for help to save the data, at least some of it if possible. Regards, Khem

The solution is to: edit: /etc/grub.d/40_custom putting in: menuentry 'name' { insmod ntfs set root=(hd0,2) chainloader +1 } note: "name" can be anything you want (within reason), and is the name that will show in the boot menu. the values here: root=(hd0,2) will vary based on your disk setup. if you still have your fc19 grub/grub2 (whichever it used) configuration file you should be able to confirm the values from that. when done, then: grub2-mkconfig -o <output file> personally, i didn't set the -o to the production grub.cfg file as my preference is to make backups and check things before potentially trashing a file like that, but do as you wish. when you're comfortable with the generated file move it to the production location and reboot. - Richard

scp -rp behavior

Hey all, I'm trying to copy configuration files from my old CentOS 6.6 32 bit machine to my new CentOS 6.6 64 bit machine. On my 32 bit machine: [mlapier@mushroom ~]$ ifconfig eth0 Link encap:Ethernet HWaddr 00:19:DB:E5:4E:9F inet addr:192.168.15.105 When I issue this command on my new 64 bit machine, 192.168.15.101: scp -pr mlapier(a)192.168.15.105: /home/mlapier/.thunderbird /home/mlapier/.thunderbird It copies all directories and files in 192.168.15.105: /home/mlapier/ to 192.168.15.101: /home/mlapier. I don't want all that, I just want the .thunderbird folder and all it's contents. The user and group account numbers match on the two machines for this user so that's not the issue. When I RTFM this is what I thought it said to do. I'm I misreading the FM or is something weird going on here? -- _ °v° /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****

I don't want to underestimate the value of good hardware RAID with BBWC implementations when it comes to avoiding problems that aren't bugs, but are "just the way things are." For example unclean shutdowns, and especially unclean shutdowns along with a device failure. There's a metric ton of really useful information in the man 4 md page that most people probably aren't aware of because they usually read the mdadm page. http://linux.die.net/man/4/md Relevant in this case is the Unclean Shutdown section. It's completely rational for people to think, hmmm, maybe I'd rather get a hardware RAID card that supports BBWC to avoid some of these problems? Plus then you get to use no barriers, resyncs and degraded operation can have much lower performance penalty, etc. -- Chris Murphy
