Dear All
To open a port , I know that I need to go to "System ->
Administration ->
Security Level and Firewall" -> Other ports and then I can open
port-5901
as tcp protocol . Can you please do me favor and let me know how it
can be
done from the command line (if my CentOS is text-mode installed) ?
(perhaps
via iptables?)
Let me thank you in advance
Edit /etc/sysconfig/iptables
Restart iptables with service iptables restart
Tony
My /etc/sysconfig/iptables states at the top that editing of it is not
recommended. Yeah, I don't always follow such recommendations myself,
but is there perhaps another way more in keeping with the sense of the
application?
Yeah, editing directly can be risky, nothing worse than making a change
only to find that access to your server just disappeared and you need to
get in front of it to reset via the console....
I use webmin for most of my edits, only make it accessible from the LAN
and not the WAN. You can always tunnel the :10000 port via ssh and
access securely from a remote location.
The webmin console is left open while I test, thus I have not yet
tripped up on this though I can imagine it is not fool proof.

Rob,
Sounds like you've thought through the process and have a well-planned
strategy for failure-prevention. Cool.
I checked my port 10000 (ssh -p 10000 ...) and found it not available
("Connection refused"). So in what sense, or how, can I always tunnel it?
tnx.

Ken, I first setup webmin on the server - this listens on port 10000 by
default (https).
Then from a remote location I can
ssh servername -L 8081:localhost:10000
This will capture local port 8081 and tunnel to the remote server port
10000.
Then with firefox I enter https://localhost:8081/
and I get the remote server's webmin.
