# conn
quick and dirty server availability check <br> <br>
basically just a way too complex wrapper for nmap and fping <br>
the pre-rewrite version is available as conn.sh.old and is no longer maintained <br>
### features:
- multi-input detection
- ipv4 input detection
- ipv6 input detection
- ~~multi-input detection~~ (not needed anymore since the rewrite)
- ~~ipv4 input detection~~ (not needed anymore since the rewrite)
- ~~ipv6 input detection~~ (not needed anymore since the rewrite)
- waiting for availability
- send notification on availability
- updater built in
# usage
