openssl file encryption | decryption

By OK -
Assuming your user and pass are stored in user.txt and pass.txt
Encrypt with:
$ openssl aes-256-cbc -salt -in user.txt -out user.txt.enc -pass file:pass.txt
Decrypt with:
$ openssl aes-256-cbc -d -salt -in user.txt.enc -out user.txt.dec -pass file:pass.txt
In order to have more secure encryption you can try to use you own complex salt with -S "your complex string". However this might be sufficient for most uses.

NFS mount add in fstab _netdev instead of default | firewall-cmd --list-all

By OK -
Redhat recommends us to add  _netdev  option for NFS file system in /etc/fstab. So that they can be mounted after starting the networking service. Alternative ways to refer to partitions: Label : LABEL=label Network ID Samba : //server/share NFS : server:/share SSHFS : sshfs#user@server:/share Device : /dev/sdxy (not recommended) Example #1 //192.168.1.134/share_name /mnt/share_name cifs username=server_user,password=server_password,_netdev 0 0 ^ Path to your share ^ Mountpoint ^ Username ^ Password ^ See note A Note A: The  _netdev  options makes sure the mount is only attempted AFTER a network connection has been established. Example #2 10.10.10.1:/vol1/fs1 /data nfs defaults,_netdev 0 0 ============================ [root@localhost ~]# firewall-cmd --list-all public   target: default   icmp-block-inversion: no   interfaces:   sources:   services: dhcpv6-client high-availability ssh   ports:   protocols:   masquera
