It's a technical term. The context is that they have been working together for a long time. There is no need to pay tribute to the relationship.

Despite efforts to increase the use of limited health-care resources, hospitalizations for infectious diseases remain a significant health burden in the United States. The case-fatality rate of invasive streptococcal disease, for example, is significantly higher in the elderly, those with diabetes mellitus, and persons of African or Hispanic descent. For each invasive case of streptococcal disease, the hospitalization costs associated with the treatment of the disease exceed $100,000 01e38acffe

In my opinion the advantage of the method below is that it is a command, in other words you can give it to a shell script. Also, any script you run it in will be able to receive the connection, so you don't have to worry about a local user not having privileges.
Here's the script we used in my lab:
#!/bin/bash
echo 'Connecting to port 22 on ip address 192.168.1.1.'
echo -n "USER: "
read -p "username: " user
echo -n "PASSWORD: "
read -p "password: " pass
echo -n "Connecting to $1..."
nc 192.168.1.1 22
exit 0
And here's how we wrote it:
#!/bin/bash
read -p 'Enter password: '
read -p 'Enter username: '
# User entered password is not echoed on the screen
# This means we do not have to worry about someone eavesdropping
echo 'Connecting to port 22 on ip address 192.168.1.1.'
echo -n 'USER: '
read -p "username: " user
echo -n 'PASSWORD: '
read -p "password: " pass
echo -n 'Connecting to $1...'
nc 192.168.1.1 22
# This script terminates immediately after nc executes, because
# we are not waiting for a connection in this example
exit 0
First of all, this is all assumed to be run from the console. You would run this script from a shell script, as I have shown.
In order to use this on our server, we added the script to our rc.local file with sudo.
sudo /etc/rc.local
Here we append our lines at the end of the file, but first we need to make sure our file is executable.
sudo chmod +x /etc/rc.local
Then we add our script to the rc.local file:
sudo vi /etc/rc.local
And finally we add our commands to the
