Hi everyone, I set up an openssh server and I am trying to access that machine remotely (not from the local network. but from another ip address). I get an error (something about port 22). What setting needs to be checked and what needs to be done on the machine that openssh server is running and on the router that machine is connected to, so that openssh server can be accessed remotely? Thank you Semih Ozlem

I know that AT&T blocks port 22 traffic and it gives that message. I set the sshd server to listen on port 26 instead and it works fine. Don MacDougall

Well to be honest I haven't tried 25 outbound but safe assumption that one is closed.
