Configuration files and/or changes to default config files in /etc/
=
# /etc: Included files
- Setup timesyncd for NTP syncing (using systemd, not ntp package)
- set to use global pool.ntp.org, you should change this!
- verify timesyncd is working with 'timedatectl' command
Three files are updated in the */etc* folder.
- Setup nano with helpful configurations both locally and via SSH
- rebind number lock
- constant show cursor position at bottom of screen
- constant show line numbers on the left
- added shortcuts for cut, copy, paste using alt-x,c,v respectively
- enable multi-buffer for concurrent open files
- cut to end-of-line
- bracket and quote matching
- tabs converted to spaces, tab = 4 spaces
- activate default colourization
## profile
- Colourize prompt
- red username for root user or shell accessed as root (su, sudo -s, etc.)
- green username for regular users
- display time and full path
This is the Debian Stretch default *profile* and is copied to */etc/profile* to
return accounts to a baseline configuration. Again, this is done to ensure that
only */etc/bash.bashrc* is providing initial customizations to users.
- Setup SSH server
- use non-standard port 222
- use host-keys (RSA and ED25519 - you need to generate these!)
- display a banner on sucessful connection
- do not allow root login
- require keyfile authentication (disable password authentication)
## bash.bashrc
Of the bash customization files, this is the only one that is NOT in a default
configuration. I have added the following customizations I find useful
especially for new users and system admins:
- colourized directory listings with built-in automatic colour settings
- changed prompt to include 24-hour clock, username, hostname and current
directory display
- username changes to RED when working as ROOT (uid=0)
- added the following command aliases
alias|full command|explanation
---|---|---
ll|ls -l|default 'ls' output
l|ls -lAsh --group-directories-first|far more useful and robust file display including sizes, permissions and owners
rm|rm -i|confirmation prompt when deleting file
mv|mv -i|confirmation prompt when moving file would result in overwriting existing file
cp|cp -i|confirmation prompt when copying file would result in overwriting existing file
## nano defaults (nanorc)
The following options have been enabled/set in nano to provide what I feel is an
easier editing experience especially for people coming from a Windows background
and new users/admins.
- 'rebind' numeric keypad to fix problems with using keypad with some SSH clients
- set 'smart home' some home key is useful
- allow opening multiple files at once
- always display line numbers
- constantly display cursor position at the bottom of the screen
- set vim lock-files
- autoindent ON, tab-size of 4 spaces
- convert tabs to spaces
- turn off hard line wrapping
- turn ON soft line wrapping for ease of readability
- closing 'brackets' (for alignment purposes) set as: "')>]}
- cut to end of line by default
- set proper bracket matching (ie. "<" matches ">", etc.)
- turned on default colours so nano doesn't look so drab
- added the following key-bindings
binding|fuction
---|---
alt-c/alt-C|copy selected text
alt-x/alt-X|cut selected text
alt-v/alt-V|paste text on clipboard
