## 3.1. SSH

Connect to `<IP>:42137`. Please note that if you select a different port by mistake, your client IP address will be blocked
|
|
instantly — literally in a few microseconds — for 86,400 seconds (i.e., one full day) due to the
|
|
|
|
* `ufw`
|
|
* `fail2ban`
|
|
* `/etc/hosts.deny`
|
|
|
|
ultimate hardening rules:

|
|
|
````text
|
|
### SSH Handling: Foreign IP (not in /etc/hosts.allow): refused to connect: immediate ban [sshd-refused]
|
|
### Jump host mistyped 1-3 times: no ban, only after four attempts [sshd]
|
|
(...)
|
|
# ufw aggressive approach:
|
|
# Any valid client communicating with our server should be going directly to the service ports opened in ufw (ssh, 80, 443, ...).
|
|
# Any client touching other ports is treated as malicious and therefore should be blocked access to ALL ports after one attempt.
