similar to: can i run NFS *exclusively* off of v4?

Hi Everyone, I have been trying to setup an NFS v4 File Server but have come across an odd issue. Mounting the /nfs4exports/share appears to be successful and the information displayed about partition size and free space seem correct but if I try to do anything inside the mounted directory the client will just hang. Does anyone have any idea what I am missing?? I have try disabling all

again, from here: http://wiki.centos.org/FAQ/CentOS5 regarding a newer version of PHP, a number of PHP experts that i know of suggest that, if you truly need an up-to-date version of PHP, you should: rpm -ivh http://rpms/famillecollet.com/enterprise/remi-release-5.rpm while remi collet's repo isn't official, it's accepted by numerous developers as a reliable source of newer PHP

NEWBIE alert: i'm a linux person, not an asterisk person so i'm certainly capable of handling any linux-flavoured solution you can suggest. here's a note i got from a local company i know (some proper names removed): ===== start ===== Now and again our ISP goes down and when it does give us a hicup, the Asterisk system shuts down (not very forgiving). When it shuts down our phone

i'm just curious -- how many people here are using ACLs as a regular and significant part of their sys admin? rday -- ======================================================================== Robert P.

Hi all, I have setup a CentOS6.3 x86_64 host to act as a nfs server. According to RHEL6 docs, portmap is not needed when you use NFSv4, but in my host I need to start rpcbind service to make NFSv4 works. My /etc/sysconfig/nfs # # Define which protocol versions mountd # will advertise. The values are "no" or "yes" # with yes being the default MOUNTD_NFS_V2="no"

ok, given the flurry of responses to my original post, let me see if i have a handle on this as i think i've finally figured it out and, yes, it does make sense. the scenario is that there is a very large software company in the area whose only officially supported linux platform is currently suse. however, they are getting increasing call to have their product run on red hat. for most

does anyone here have pointers or access to courseware that could be used to teach centos (5.4, i believe)? publicly-available, free C/W would, of course, be ideal, but if you have some decent training manuals that you're willing to license on a per-manual basis, i'm still willing to chat. rday -- ======================================================================== Robert P.

someone just pointed out to me that there is a distro called "oracle enterprise linux" which is effectively a re-branded RHEL, so i'm curious -- has anyone here used both centos and OEL and would there be any differences that would be worth caring about? the only thing i can think of that might be worthwhile is that OEL might change some of the default kernel parms thru

yes, it's OT but just in case folks here know someone who might be interested, i'm writing and publishing a course to introduce people to the joys of linux kernel programming: http://www.crashcourse.ca/introduction-linux-kernel-programming/introduction-linux-kernel-programming and, no, it's not free -- six months worth of course will cost you all of $39 (CAD), but the first four

it's been a while since i've played with filesystem encryption so, on centos 5.4 (and other linux distros), is dm-crypt/LUKS considered to be the state of the art WRT encryption? i remember other solutions like loop-aes and others, but what's considered the gold standard these days? rday -- ======================================================================== Robert P.

here's hoping this is on topic. as part of the extra goodies i'm going to give my RHEL/centos basic admin class this week, i'm going to get them to open up the standard initrd.img file and see what's inside. i just did that myself and have a couple simple questions. first, while the cpio archive physically contains a number of basic /dev special files, the top-level

as i'm reviewing the courseware for the rhel (centos) course i'm teaching next week, i'm going to ask the occasional question, possibly technical, possibly more policy. first one involves the choice for virtualization. the course has a short section involving virt using xen but everything i've read suggests that red hat is concentrating on kvm for virt. thoughts on that? i

at the risk of picking at that scab a bit longer, i'm going to toss out a comment regarding people still waiting for the public availability of centos 5.4. here: http://lists.centos.org/pipermail/centos/2009-October/083743.html we read: "The last status (from twitter) is 2 days old with the '5.4 is baked! centos internal network will start syncing up today. Release ~ soon!'.

i'm experimenting with some basic removable media mounting exercises for an upcoming class, and i read that, while you can use gconf-editor to change some of the mount options in cases like that, there is no way to override the mount options of nodev, noexec and nosuid. for example, that claim is made here (admittedly for fedora, but it appears to be true for centos as well):

Hi all, Which ports do I need to have open on an NFS client's firewall to allow it to connect to a remote NFS servers? When I disable iptables (using ConfigServerFirewall), it connects fine, but as soon as I enable it, NFS gives me this error: root at saturn:[~]$ mount master1.mydomain.co.za:/saturn /bck mount: mount to NFS server 'master1.mydomain.co.za' failed: RPC Error: Unable to

a couple folks on the local mailing list were asking about the mechanics of building a kernel for a centos system, and they seemed to suggest that there were some intricacies involved as opposed to other distros. i've never tried it -- is there a trick or something? got a pointer to the canonical web page that has the directions? thanks. rday --

a student in my RHEL admin class this week specifically asked how to use multiple NICs to add fault tolerance. a good question, i thought. perhaps adding a short HOWTO on that wouldn't be out of line, something like this: http://www.how2centos.com/how-to-set-up-network-bonding-with-centos-5x/ i could even add that as a lab for future classes, where i simply add two USB network adapters to

yesterday, i was demoing how to use ssh-copy-id on centos 5.5 to copy one's public key to another machine and account so you don't need to type the password anymore. i used "ssh-keygen" to create the standard RSA-format files, then checked the man page for ssh-copy-id, which reads: ssh-copy-id [-i [identity_file]] [user@]machine ... If the -i option is given then

more a terminology usage question than anything else, but in a couple of weeks, i'll be teaching the first of a few sessions on RHEL admin and, unsurprisingly, i'll be using centos (as i've done in the past). when i asked the organizer to identify the specific version of RHEL that was being used at the client site, i was told 5.3 so i can easily install 5.3 on the classroom

i'm sure there's a simple answer to this -- i already understand that newer kernels than the ones shipped with the official release aren't officially supported but there is the elrepo kernel repository here: http://elrepo.org/linux/kernel/el7/x86_64/RPMS/ with a mixture of long-term (lt) and mainline (ml) kernels. i assume that the mainline kernels pretty closely track the latest
