nfs4 problem in CENTOS6
by Michael Schumacher 18 Nov '11

18 Nov '11

Hi, This is slightly offtopic, but I have been trying to resolve that problem for two days now without much success. It looks like this may be something that works with CENTOS5, but not with CENTOS6! I have two machines, fileserver1 and server5. fileserver1 runs on CENTOS6 (virtualized, if this is important), server5 runs on Centos5. Both are running with the most recent updates. Server5 is a machine to store backups on. Several servers, including fileserver1, are mounted with nfs4 on … [View More]server5. fileserver1 has this /etc/fstab: ---8<---/etc/fstab--- UUID=73254e19-895f-4190-b2e3-13a2b0bec9ce / ext4 defaults 1 1 UUID=ac658802-73e4-4c87-bb03-6f9af1ebc4f8 /mnt/data ext4 defaults 1 2 UUID=4836335a-2d66-4d12-9dec-7197dc772d77 swap swap defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 /mnt /mnt dazukofs / /nfsexport/root none bind 0 0 /mnt/data /nfsexport/data none bind 0 0 ---8<--- AS you can see, /mnt/data is a partition mounted below /. I am binding both partitions to /nfsexport/... and export them in /etc/exports with ---8<---/etc/exports--- / server*.pamas.local(ro,secure,no_root_squash,crossmnt,fsid=0) /mnt/data server2.pamas.local(ro,secure,no_root_squash,nohide) server5.pamas.local(ro,secure,no_root_squash,nohide) ---8<--- If I execute [root@server5 ~]# /etc/init.d/nfs reload I get exportfs: /mnt/data does not support NFS export exportfs: /mnt/data does not support NFS export on the console, but nothing in the log-files. On server5, I entered [root@server5 ~]# mount -t nfs4 192.168.1.202:/ /mnt/nfs/fileserver1/root successfully and [root@server5 ~]# mount -t nfs4 192.168.1.202:/mnt/data /mnt/nfs/fileserver1/data returns: mount: pinging: prog 100003 vers 4 prot tcp port 2049 and hangs. ctrl-c returns me to the prompt, but /mnt/data is not mounted. The active mount /mnt/nfs/fileserver/root is working nicely, but if I cd into /mnt/nfs/fileserver/root/mnt and enter ls there, the console hangs infinetly. As I wrote, server5 also mounts other servers filesystems without problems. All working systems are CENTOS5, the one not working is CENTOS6. Any idea? best regards --- Michael Schumacher [View Less]

CentOS 6 smb authentication?
by Les Mikesell 18 Nov '11

18 Nov '11

I have some services on Centos5 boxes that use smb authentication against the Windows domain as a low-maintenance way to handle most of our office users for things that don't need home directories (web/file shares, etc.). Running authconfig is all it takes to add it to PAM, then adding mod_auth_pam to apache makes it work with that and local users. This all works without any particular involvement with the Windows group or administrative access there. Is there a better way to do this on C6 … [View More]

Hello, I've on my home PC CentOS 6 and Fedora 13 on different disks. When I log on the gnome enviroment at Fedora knows exactly which programm was started at which desktop (for example: thunderbird on desktop 1, firefox on desktop 2, nautilus on desktop 3, ..). The same procedure on Centos takes all programs on the first desktop, so I must arrange the programs on the right desktop. Question: why kows the gnome of Fedora al the postions and the gnome from CentOS doesn't? Is there a way to … [View More]

I have an ethernet device in my lan with a primary address 192.168.5.205 and a secondary address .217.
