• mkdir /mnt/app → create mount point

• mount 192.168.0.100:/myshare /mnt/app

  • Mount NFS file system

• df -h → verify mounted system

• umount /mnt/app

SAMBA

• SMB → Server Message Block

• CIF → Common Internet File System

• Samba protocol

• dnf install samba samba-client samba-common

• firewall-cmd --reload

  • Add rule to firewall

• mkdir -p /samba/myshare

• chmod a+rwx /samba/myshare

• chown -R nobody:nobody /samba

  • Create Samba share directory

• chcon -t samba_share_t /samba/myshare

  • Change SELinux security context

• nano /etc/samba/smb.conf

[anonymous]
path = /samba/myshare
browsable = yes
writable = yes
guest ok = yes
guest only = yes
read only = no

• testparm

  • Test SMB configuration

• systemctl enable smb

• systemctl start smb

  • Start Samba service

Mount on Linux Client
