i'm having problems with ssh. I have many hosts in a private subnet, and all this hosts have to access a host with a public IP outside the subnet. i've done the correct forwarding in a PC-router which is the default gateway. Every host in the subnet can access the other host with public IP with ping command.
The problem is that some host can do ssh to that public IP properly, but other host, after enter the correct password cannot access the machine:
Permission denied, please try again.
what do you think is goig on?
