remote access via SSH from 2222 ?

[zodehala]

this my network :




i can not access centos from remote via port 2222

i forward 2222 to centos IP (192.168.1.250) from modem
and
i have changed default port to 2222 from sshd_config
and
i accept all tcp request from port 2222

iptables -A INPUT -p tcp --dport 2222 -j ACCEPT

but still i can not

what will i do for firewall or other ? what is problem for you ?

As I see it in the diagram you are trying to access the system from outside the network, which would require you to forward in the router, have you done that? If not make sure your forwarded box gets a static IP so you don't have to change the settings in the router, each time the dhcp release runs out.

try to disable the Selinux .
and nmap the pc from other machine
nmap ssh-host (should give you of the port is open or not)

1- i have static IP
2- İ forwarded in router

fromwhere can i disable selinux and nmap ?

This may seem silly to ask, but did you restart the sshd service after configuration?

The first thing I would try is to turn off iptables (service iptables stop) and try ssh. If it works then you have something wrong with iptables. I'd also make sure you aren't using tcp_wrappers (/etc/hosts.allow and /etc/hosts.deny).

I would not turn off SELinux, but you can set it to Permissive mode with

setenforce Permissive

Then you can enforce SELinux again with

setenforce Enforcing

Sorry, but I've never heard about disabling NMAP so I can't help there.

I hope I was some help.
