✅ 1. Check Windows Firewall Rules

🛡️ Allow SSH (Port 22) and ICMP (Ping) Through Firewall

👉 Enable SSH in Firewall:

Run this in PowerShell as Admin:

New-NetFirewallRule -Name sshd -DisplayName "OpenSSH Server" -Enabled True -Direction Inbound -Protocol TCP -Action Allow -LocalPort 22

👉 Enable Ping (ICMP Echo):

New-NetFirewallRule -Name ICMPAllow -DisplayName "Allow ICMPv4-In" -Protocol ICMPv4 -IcmpType 8 -Direction Inbound -Action Allow

✅ 2. Confirm SSH Service is Running and Listening

Check service:

Get-Service sshd

Check it's listening on port 22:

netstat -an | findstr :22

You should see something like:

TCP    0.0.0.0:22      0.0.0.0:0     LISTENING

✅ 3. Check Network Profile (Set to Private)

If the network is set to Public, Windows firewall blocks incoming connections by default.

Change to Private:

• Go to Settings > Network & Internet > Ethernet or Wi-Fi
• Click your network
• Set Network profile to Private

---

✅ 4. Check IP and Reachability from Remote Machine

On the remote machine:

ping 192.168.1.100
ssh username@192.168.1.100

If still no luck, run:

telnet 192.168.1.100 22

If connection fails, it confirms port 22 is blocked or unreachable.
