I have seen some talk about this but have not seen any answers. I know this is a problem on CentOS 7.1 and I also think it is a problem on CentOS 7.0. Basically if I have an NFS client only config - meaning that the nfs-server.service is not enabled then I have to wait 60 seconds after boot for the 1st NFSV3 mount to succeed. What I can surmise is the following. I attempt to perform a NFS

Hello all, I have an NFS Server where I want give access to a specific address to a specific path. Problem is that I have some other shares active which I do not want the specific IP to not access it. The /etc/exports looks like the following: /nfs/Share1??? ??? ???? 10.10.*(rw) /nfs/Share2?? ? ??????? 10.10.*(rw) /kdnbckp/CS21?????????? 10.10.193.43(rw) The client on the last line (IP

In the old days NFS Shared Path had a static handle (ie a number), normal based on some number pulled out of the file system/inode. To fix (well work around) a security issue, for about 10+ years now, when a NFS server reboots, it generates a new random handle for the NFS Share. (sever may generate a new random handle per mount request) The NFS Stale Handle happens when the client is still

I''m seeing some pretty pitiful performance using ZFS on a NFS server, with a ZFS volume exported (only with rw=host.foo.com,root=host.foo.com opts) and mounted on a Linux host running kernel 2.4.31. This linux kernel I''m working with is limited in that I can only do NFSv2 mounts... irregardless of that aspect, I''m sure something''s amiss. I mounted the zfs-based

Hello, I set up NFSv4 server. To make sure I set vfs.nfsd.server_min_nfsvers=4. I can check its version, for example, by tcpduming and then I can see in wireshark lines like: Network File System Program Version: 4 V4 Procedure: COMPOUND.... .... is there any easier way to check its version? I see there is nfsstat -e option which shows delegs and locks. But all other ones are combined with nfsv3

Hi, I've seen some chatter on NFS boards about kqueue being more reliable than inotify when used in NFSv3 and NFSv2. The chatter is a bit old so I don't know if it is true anymore. Anyone have pro/con experience with dovecot on the inotify/kqueue question when using NFS storage? I realize that kqueue is probably a bit slower and causes some delay with IDLE. Also, it may not really

Hi, I'm looking for recommendations for documentation about the specificities of RHEL/CentOS 7.x. It can be either online or in printed book format, and I'm fluent in german, french and english. I have a good books about 5.x: "RHEL 5 Unleashed" from Sams, "Foundations of CentOS Linux" and "The Definitive Guide to CentOS", both from Apress. Can anyone

Hello, I'm migrating from 1.1.16 running in 4 debian lenny servers virtualized with xenserver and 1 core and 5GB of RAM to 2.1.5 running in 4 ubuntu 12.04 servers with 6 cpu cores and 16GB of RAM virtualized with VMWare, but I'm having lots a performance problems. I don't think that virtualization platform could be the problem, because the new servers running in xenserver has

As is usually the case, I'm not sure enough of what the DC docs are referring to; there are some implicit info assumptions that I, the Newbie, miss... Anyway, here is my situation Dovecot is to run on one machine only, its index files are stored in on a separate, non-quotaed, not NFS filesystem. INBOX and folder filesystems (all mbox format) are native to this machine and are NFS

Hi, What's the most simple way to check if my microphone works on a plain CentOS 5.3 desktop? Is there a simple way, for example, to record voice into a simple .wav file? Niki

Hi, I'm currently installing a CentOS 5 desktop as a public internet access point. The machine shuts down every day automatically at 22:30. Is there a way I can display a message in GNOME at 22:15 warning the user that the machine will shutdown in 15 minutes ? Any suggestions ? Niki Kovacs

That is the thing - rpc.statd does have rpcbind a pre-req. It looks like systemd is not handling this correctly. Just wondering if anyone knows a good way to fix. root at ls2 /usr/lib/systemd/system 110# grep Requires rpc-statd.service Requires=nss-lookup.target rpcbind.target On 8/30/15 7:45 PM, Rob Kampen wrote: > On 08/31/2015 01:39 PM, Mark Selby wrote: >> I have seen some talk

Hi, I just set up a web server... and my bandwidth is being eaten by some chinese folks trying to brute-force-ssh their way into the machine. Is there a simple way to banish either single IP addresses or, maybe even better, whole IP classes ? I know it's feasible with iptables, but is there something more easily configurable ? Cheers, Niki

The problem you've described is definitely an NFSv3 problem.? The connections causing the client to hang are portmap connections. They're dynamic, and don't necessarily conform to /etc/services.

Hi Stephen, I use ext3 with kernel 2.4.14. I'm happy to have verified that nfs+ext3 in journal mode doesn't provide atomic write for the user point of view. My program writes sequential records of 64KB in a file through a nfs mount point. The blocks of data are initialized with a serie of integer: 1, 2, 3 ... I kill the nfsd daemons while two instance of the program are writing their 600

Hi, I'm using CentOS on server and desktop since 4.2, and I'm quite happy with it. Can you recommend some complete documentation besides the RHEL Deployment Guide? For example, I have a big fat paper book "FreeBSD Unleashed", 700 pages chock full of useful information. Now I wonder if you can recommend something similar for CentOS (RHEL / Fedora). cheers, Niki

Hi, Over the last few years, I've been using a rather bone-headed solution to implement centralized authentication and roamin user profiles in Linux-based networks: a combination of NIS and NFS. I'm aware it's not ideal in terms of security, but it's been running in our local school since 2010, and it just works. The current setup is based on Slackware Linux on both server
