NFS Stale file handle drives me crazy (Centos 6)
by Götz Reinicke - IT Koordinator 08 Apr '15

08 Apr '15

Hi folks, I have a Centos 6 NFS server, which dirves me crazy. The directory I try to export cant be accessed by different clients. I tried a centos 7, centos 6 and a pool of vmware esxi 5.5 systems. At the client side I get errors like: mount.nfs: Stale file handle or Sysinfo set operation VSI_MODULE_NODE_mount failed with the tatus Unable to query remote mount point's attributes. On the server I get messages in the log like svc: 172.17.252.35, port=851: unknown version (0 for prog 100003, nfsd) rpc.mountd[1927]: authenticated mount request from .... The curious thing is, that other directories exported on the same filesysten can be exported. so /home/stuff works /home/students fails. chmode 777 is set, /etc/exports is double checked. nfs/rpc/etc is up and running. selinux & firewall for debugging off. I use xfs on all shared filesystems. Googling for VMWARE and native NFS suggestions did not help so far :-/ Any hint or suggestion is very very welcome! Regard & thanks .

Linux Australia breached, personal details leaked
by m.roth＠5-cent.us 08 Apr '15

08 Apr '15

FYI, folks, Excerpt: Linux Australia discovered the breach on March 24 after it noticed conference management software it uses called Zookeepr started sending a large number of error reporting emails, Hesketh wrote. A server had been attacked two days prior. “It is the assessment of Linux Australia that the individual utilized a currently unknown vulnerability to trigger a remote buffer overflow and gain root level access to the server,” Hesketh wrote. The attacker installed a remote access tool and then botnet command and control software. --- end excerpt --- <http://www.cio.com/article/2906814/linux-australia-breached-personal-detail…> mark

For a non-technical person, your brief clues them in to the differences between RHEL and CentOS. And the reason both coexist. I do however agree with Valeri in that you probably (c|s)hould mention Debian in there somewhere. I realize you left Debian out because there is no official "enterprise" support entity as there is with Ubuntu. So at that point, maybe it's not worth mentioning Debian? > > > I for one welcome our Redhat overlords.

Which is not an issue given that no httpd service is, or will ever be, installed on that host. However, it seems a rather dangerous hole in the logical design of SELinux that one cannot explicitly remove and reassign contexts to ports. In order to accomplish this on a system running httpd but attached to non-standard ports one perforce is required to cross link permissions between all of the affected processes. Which I cannot conceive as a security enhancement. -- *** E-Mail is NOT a SECURE channel *** James B.

tcsd service fails on boot because device missing
by Laurent Blume 07 Apr '15

07 Apr '15

Hello all, On CentOS 7.1, I activated the tcsd service. When I did it manually, it worked without problem, however, on reboot, I noted it was failed. I restarted it, and it worked immediately. But more reboots confirmed that it's always failing when the system starts. It seems the service is started too early, before the device it uses is created. Here's the logs: # journalctl -u tcsd -- Logs begin at Mon 2015-04-06 10:20:59 CEST, end at Tue 2015-04-07 10:11:37 CEST. -- Apr 06 10:21:38 server systemd[1]: Starting TCG Core Services Daemon...

filesystem corruption?
by m.roth＠5-cent.us 07 Apr '15

07 Apr '15

Got an older server here, running CentOS 6.6 (64-bit). Suddenly, at 0-dark-30 yesterday morning, we had failures to connect. After several tries to reboot and get working, I tried yum update, and that failed, complaining of an python krb5 error. With more investigation, I discovered that logins were failing as there was a problem with pam; this turned out to be it couldn't open /lib64/security/pam_permit.so. The reason for that was that it was a broken symlink, pointing to a file in the same directory, that actually existed in the /lib64. Checking other systems, I found it should, in fact, be a file, not a symlink. At this point, the system was considered suspect. I brought the system down, replaced the root drive, and rebuilt. I was not able to build it as CentOS 7, as something in the older hardware broke the install. CentOS 6 built successfully, and the server was returned to service. I then loaded the drive in another server, and examined it. fsck reported both / and /boot were clean, but when I redid this with fask -c, to check for bad blocks, it found many multiply-claimed blocks. First question: anyone have an idea why it showed as clean, until I checked for bad blocks? Would that just be because I'd gracefully shut down the original server, and it mounted ok on the other server? Mounting it on /mnt, I found no driver errors being reported in the logs, nor anything happening, including logons, before an automated contact from another server, which failed. AND I checked our loghost, and nothing odd shows there, neither in message nor in secure. At this point, I *think* it's filesystem corruption, rather than a compromised system, but I'd really like to hear anyone's thoughts on this. mark

Satellite sync (spacewalk) of configuration channels?
by Christopher Jacoby 06 Apr '15

06 Apr '15

Hello all. I have inter-Satellite sync set up and working on two Satellite servers downstream from a development Satellite server. Channels sync up fine, but I would like to sync up system groups and configuration channel content as well. Any ideas? Thanks, Chris

Import Nautilus file notes from C6 Gnome to C7 Mate
by Frank Cox 06 Apr '15

06 Apr '15

With C6 Gnome and C7 Mate you can right-click on a file icon, select Properties, select Notes, and write notes about your file. Does anyone know if those notes can be directly transferred between C6 Gnome and C7 Mate? I'm looking into upgrading someone's desktop machine to C7 and she has a lot of notes attached to her files that she doesn't want to lose. After doing a bit of experimenting, I think the notes are actually stored in a file named ~/.local/share/gvfs-metadata/home Can I just copy that "home" file into the new C7 Mate desktop and have the file notes move in automatically, or do I have to somehow extract the notes and re-import them? Any suggestions will be appreciated. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com
