mount.nfs: Operation not permitted
I’m used to seeing command not respond or timeout because CSF is blocking it but never Operation not permitted.
This is the basic install I did and it works with CSF is off:
—
1. Install rpcbind
$ sudo yum install rpcbind
2. Install NFS-related packages:
$ sudo yum install nfs-utils nfs-utils-lib
3. Once installed, configure the nfs, nfslock and rpcbind to run as daemons:
$ sudo chkconfig –level 35 nfs on
$ sudo chkconfig –level 35 nfslock on
$ sudo chkconfig –level 35 rpcbind on
4. then start the rpcbind and nfs daemons:
$ sudo service rpcbind start
$ sudo service nfslock start
$ sudo service nfs start
5. Allow NFS through CSF firewall:
$ sudo vi /etc/sysconfig/nfs
and set:
LOCKD_TCPPORT=32803
LOCKD_UDPPORT=32769
MOUNTD_PORT=892
RQUOTAD_PORT=875
STATD_PORT=662
STATD_OUTGOING_PORT=2020
6. then restart nfs daemons:
$ sudo service rpcbind restart
$ sudo service nfs restart
7. then open nfs ports in CSF firewall:
$ sudo vi /etc/csf/csf.conf
tcp 111,662,875,892,2049,32803
udp 1ǫ,662,875,892,32769
8. Restart CSF:
$ sudo csf -uf
Solusion :
csf -a nas-ip
