Linux Tips and Tricks

Linux stuff I often have to lookup. Just my personal list of things.

shutdown -rF now
xauth add `hostname`/unix:0 . `openssl rand -hex 32`
  • yum versionlock - allows to lock an rpm
  • install faster random for dns etc.
 yum install haveged;
 systemctl enable haveged;
 systemctl start haveged
sudo visudo -f /mnt/etc/sudoers
netstat -tulpn
xargs yum -y install < file
  • Create Default Home Directory
mkhomedir_helper username
use tmpfiles.d and have your package create at startup or boot a file or directory /usr/lib/tmpfiles.d/mydaemon.conf :
man tmpfiles.d

#Type Path            Mode UID      GID    Age Argument
d     /run/mydaemon   0755 myuser myuser   -   -
rpm -Uvh --nodeps $(repoquery --location <module>)
  sudo journalctl --vacuum-time=3weeks
  ip -br l | awk '$1 !~ "lo|vir|eth" { print $3 }'
