A daemon that watches all SSH/SFTP login entries on the authentication log (usually
/var/log/auth.log) and e-mail them to yourself. It works like a very simple intrusion detection system, informing you about any successful logins on your SSH server. Written entirely in Python, you just need:
- A Linux box (maybe anything *NIX, but was tested only on Linux) running a SSH server (OpenSSH or Dropbear).
- Python 2.x (it was developed on the 2.6.6 release, but will probably run on anything higher than Python 2.4).
- Read access to /var/log/auth.log (you didn't though you could analyse the log without reading it, didn't you?).
- Write access to /var/run/ (to be able to terminate it's execution through 'stop' command).
- Local SMTP server (like Exim or Sendmail).
Installation and Usage
Just put the
sshmon.py file anywhere you want, run with:
python sshmon.py firstname.lastname@example.org
And forget it. You don't have to do anything after that, just wait your e-mails to arrive. It is also possible to run it every boot by putting the same command on the
If you want to stop it, type:
python sshmon.py stop
