It seems that you have lost your way. Allow me to point you into right

A documentation of this distribution mentions that you should, to quote
'Add a Firewall Rule to allow VNC traffic IN'. Presumably something
similar should be done with SSH.

See above, replace SSH with RDP.

Don't disable it. Just allow whatever incoming connections you need.

Hi,

openssh-server is linked against libwrap0 which in turn is controlled by the
files /etc/hosts.deny and /etc/hosts.allow.

What is the content of these files on your system?

Regards,
jvp.

Difficult to tell without knowing a bit more. With only the hints you've
given it seems a bit early to blame the firewall.

 1) is there any connectivity between "remote" and "local" (I'm trying
to use your terminology above)

 2) Is IP working between both machines? Do both have IP addresses?
Which? Is there a route from one to the other? E.g. from "local"
try in a command shell "ping remote" (how do you spell "remote"?
by its IP address?) and look carefully at the command's output.
Post all that here. From the command's output you can differentiate
between a routing failure, a name resolving problem (*if* you
are going by host names, which we don't know yet) or packets
not arriving.

In short, more details needed :-)

regards

is there a firewall which blocks the connection

2017-05-03 Thread Abdelkader Belahcene
Hi everybody,
I installed the latest release of linuxlite,
The  openssh-server is installed, i can access from the local machine via
ssh,  but not from a remote machine.
Something like a firewall blocks the connexion ???  the connection ??. I
didn't activate any firewall , I use it as I installed it.

I have the same problem with xrdp:   I can connect with rdesktop from the
local machine , but not from a remote one

for this reason I suspect firewall, if so hoe to disable it !!
thanks  a lot for help
