This question already has an answer here:
Ssh login hook?
2 answers
I am installing a server; I am preparing it for SSH traffic.
I would like a script to be run (a dialog with the freshly connected user) every time a user from a certain group connects.
How do I do this (kind of like in the SSH hook post)?
I want a certain a group, which i will just call users, who just want to launch a game server or something like that, to be able to do so with minimal headache. And my idea is to make a script, which launches everytime they connect, that takes their hand and allows them to execute different actions, all centered around that game server thing. I don't want admins to be bothered every time by that script.

Why not with the /etc/profile file on the server, with one condition?
For example: Only for the group player, the script /etc/profile-grp/player is executed (sourced from /etc/profile) .
It writes the date in a log file (~/log) of the user's directory.
grp=player
# Write a script
sudo mkdir /etc/profile-grp
echo "date >> ~/log" | sudo tee /etc/profile-grp/$grp
# Script permissions
sudo chown root:$grp /etc/profile-grp/$grp
sudo chmod 640 /etc/profile-grp/$grp
# In /etc/profile
echo "
if ( groups | grep $grp > /dev/null); then
. /etc/profile-grp/$grp
fi" | sudo tee -a /etc/profile
unset grp
- Only the player group (and root) can read the script.
- Free to edit the script. Only root can change it.

Some Options:
- Change each users login shell, to be the interactive script.
- Edit/copy each users .profile, this is run each time that bash is started when it stops the user gets their prompt.
- Edit users ~/.ssh/authorized_keys, so to tell ssh to run a special command when user connects. This is like option 1, but for
sshonly. It can also be used to allow many people with different keys to log into same account, but have different action (user separation, by action).
