My current bash prompt looks like this (nice and simple): It's created using the following value for PS1 in bash profile: PS1="\[$txtgrn\]\h::\u [\[$txtpur\]\W\[$txtgrn\]]\$ \[$txtrst\]" I've configured the various different servers I use to be different colours, and all of them to be red when running as root. Follow the guide on ArchWiki. txtblk='\e[0;30m' # Black - Regular txtred='\e[0;31m' # Red txtgrn='\e[0;32m' # Green txtylw='\e[0;33m' # Yellow txtblu='\e[0;34m' # Blue txtpur='\e[0;35m' # Purple txtcyn='\e[0;36m' # Cyan txtwht='\e[0;37m' # White bldblk='\e[1;30m' # Black - Bold bldred='\e[1;31m' # Red bldgrn='\e[1;32m' # Green bldylw='\e[1;33m' # Yellow bldblu='\e[1;34m' # Blue bldpur='\e[1;35m' # Purple bldcyn='\e[1;36m' # Cyan bldwht='\e[1;37m' # White unkblk='\e[4;30m' # Black - Underline undred='\e[4;31m' # Red undgrn='\e[4;32m' # Green undylw='\e[4;33m' # Yellow undblu='\e[4;34m' # Blue undpur='\e[4;35m' # Purple undcyn='\e[4;36m' # Cyan undwht='\e[4;37m' # White bakblk='\e[40m' # Black - Background bakred='\e[41m' # Red badgrn='\e[42m' # Green bakylw='\e[43m' # Yellow bakblu='\e[44m' # Blue bakpur='\e[45m' # Purple bakcyn='\e[46m' # Cyan bakwht='\e[47m' # White txtrst='\e[0m' # Text Reset
When configuring a Samba server, remember that the discovery of machines on the network happens not only with DNS but also with a few other mechanisms too. I recently setup a number of virtual machines for developers, that were created by cloning a single instance. Mistakenly, I thought that adding a DNS config entry for each virtual machine on the host's /etc/hosts would be enough, but it's not. What we found was that everyone was connecting to the same VM (another requirement was that they be on the same subnet).
