from cli I get:
mysshbanner
*******************************************

* Welcome! ..... now leave please! *

You are coming in from 192.168.1.33 port 42120
*******************************************
from starting ssh session I get:
ssh manuel@(removed)
#!/bin/bash
echo "*******************************************"
echo "* *"
echo "* Welcome! ..... now leave please! *"
echo "* *"
if [ -n "$SSH_CLIENT" ]
then
set $SSH_CLIENT
echo "You are coming in from $1 port $2"
fi
echo "*******************************************"

Actually, forget what I wrote in #2 above. michaelk's answer prompts me to remember that the manual page for sshd contains a quiet mention of /etc/ssh/sshrc, which is the global equivalent of ~/.ssh/rc.
Code:
man sshd
You can just put the working parts of your script into /etc/ssh/sshrc and it will run upon login with SSH.
I do a similar thing. But I just use a common .bashrc file that I copy to every machine I have access to. Modifying it to get what you want would be something like this:
Code:
if [ -n "$SSH_CLIENT" ]; then # Logged in via SSH
p=${SSH_CLIENT#* }
echo "You are coming from ${SSH_CLIENT%% *} port ${p% *}"
unset p
fi
