Putty for mac raspberry pi6/21/2023 ![]() I am using a different username and password and the default Pi user no longer exists. If you will only be connecting to your home network from a static IP address, I would strongly advise configuring your router (probably on the same settings page where you setup the Port Forward rule) so that it only accepts inbound ssh connections from specific, known, IP addresses that you specify.īy default, Raspbian is extremely insecure, which is tolerable on an isolated, home LAN but not so much when visible to and accessible by the entire internet. I would also investigate tools such as sshblack (useful installation here) that automatically blacklist IP addresses that fail to login via ssh (thus foiling any potential brute force attack). ![]() At the very, very least, you must change the default pi password to something much stronger than "raspberry".

Just sayin', before anyone puts an unsecured device (Raspbian or otherwise) on the internet. I'm sure most of these "attacks" are not actual DoS attempts, but these IP addresses that are being logged shouldn't be connecting to me at all so they're up to something. Reveals an average of 380 attacks per day (January looks like being a busy month), and that's just the activity perceived as "Dos Attacks", so there may be even more that simply aren't being logged. Is it possible to set the Pi to use more than one port for SSH? They have different IP addresses so I can use puTTY on my local network to start up interfaces on both the ethernet and the wireless at the same time. I was able to access the Pi using puTTY (but not directly via a web browser) but I had to go into my router and disable one of the Pi interfaces because both the ethernet and the wireless use the same port. Let me know if that doesn't make sense and I will write an example with default ip addresses. It sounds as though the address you have used to connect to your router (probably 192.168.1.1 or similar) is not the router's external ip address, but is its address within your home network. This means that you cannot have two devices available for ssh on the same home network, unless one of them is set up to receive ssh through a different port (and the client connection request must reflect this). This is achieved by assigning an incoming target port to a particular ip address on the internal network - ssh uses port 22 so the router should be set up to forward all external requests targeting port 22 to the raspberry pi. ![]() When an incoming connection arrives the router needs to know which machine on the network should receive it, since they all have the same internet address. Most home networks have one external ip address - that of the router. But doesn't that just log you into your router? How do you get from the router external IP address to the Pi? I'm not outside of my own network at the moment, but using my router's external address (not the internel network gateway address) just puts me at the router login screen.
