Here are some examples that I’ve tested on Ubunt
SAMBA
Edit samba configuration:
nano /etc/samba/smb.conf
Share example:
[share_name]
guest ok = yes
path = local_shared_dir
available = yes
read only = no
browseable = yes
public = yes
writable = yes
create mask = 0777
Restart samba:
systemctl restart smbd
(stop, start)
NFS
SERVER:
Edit server NFS configuration:
nano /etc/exports
Share example:
/local_shared_dir 192.168.xx.0/24(ro,sync,no_subtree_check)
Export “NFS table” (this is necessary after NFS edit) :
exportfs -a
Restarts NFS to apply changes:
systemctl restart nfs-kernel-server
CLIENT:
Share mounting examples:
terminal:
mount ser.ver.ip.address:/remote_share_dir /local_share_dir
fstab:
ser.ver.ip.address:/server_dir /local_mounting_dir nfs defaults 0 0
PROCESSES
Dynamic real-time view of processes:
top
Search processes by name:
pgrep name_of_the_process
List processes by user:
ps -u username
Scroll the process list vertically and horizontally:
htop
(apt-get install htop)
kill -9 name_of_the_process
Kill process by name without allowing process to do cleanup or restart
killall -9 PID
Kill process by PID without allowing process to do cleanup or restart
TAR
Create archive from directory or a single file:
tar -czvf archive.name.tar.gz /target.dir
Extracts archive:
tar xzvf archive.name.tar.gz
Extracts archive in target directory:
tar xzvf archive.name.tar.gz -C /target.dir
NETWORK INTERFACES
Lists available:
ifconfig -a
List available with more info:
ip link show or ip addr or ls /sys/class/net
TIME ZONE
Current time zone info:
timedatectl
List available time zones:
timedatectl list-timezones
- Europe/Belgrade
- Europe/Berlin
- Europe/Brussels
- Europe/Bucharest
- Europe/Budapest
- Europe/Chisinau
- Europe/Copenhagen
- Europe/Dublin
Set your timezone
timedatectl set-timezone your_time_zone
another way
Unlink localtime file:
unlink /etc/localtime
Seting local timezone:
ln -s /usr/share/zoneinfo/Europe/Belgrade /etc/localtime
To set the timezone this way you must unlinki localtime file
