## User logins monitoring (*nix)
Watchdog can send notifications on user login. Just add to ```/etc/profile.d/sshinfo.sh``` next lines:
- For Telegram:
1. ```User=$(whoami)```
1. ```send-telegram "SSH: User ${Users} is logged in"```
- For e-mail:
1. ```User=$(whoami)```
1. ```send-mail your@mail.addr 'SSH: User ${Users} is logged in' 'SSH: User ${Users} is logged in'```
## User logouts monitoring (*nix)
1. Create file ```/etc/pam.d/pam_session.sh``` with next content:
For Telegram:
```
#!/bin/sh
if [ "$PAM_TYPE" = "close_session" ]; then
send-telegram "SSH: User is logged out"
fi
```
For e-mail:
```
#!/bin/sh
if [ "$PAM_TYPE" = "close_session" ]; then
send-mail your@mail.addr 'SSH: User is logged out' 'SSH: User is logged out'
fi
```
and set executable flag on it
1. Modify ```/etc/pam.d/sshd```, add line ```session optional pam_exec.so quiet /etc/pam.d/pam_session.sh```
