Breaking the telnet addiction with netcat

After many years of use it’s become almost second nature to type ‘telnet <HOST> <PORT>’ when I need to see if a system has TCP port <PORT> open. Newer systems no longer install telnet by default:

$ telnet google.com 80
-bash: telnet: command not found

I can’t think of a valid reason to keep telnet around (there are probably valid use cases). Since netcat and tcpdump are a billion times better for debugging TCP issues, I need to apply newer microcode to my brain to perform a ‘s/telnet/nc -v/g’ each time I need to test if a TCP port is open:

$ nc -v google.com 80
Connection to google.com 80 port [tcp/http] succeeded!

Anyone else have a telnet attachment they just can’t break? :)
