No problem, that's for ubuntu though. Here's the CentOS 6 one.
Ninja edit: The tutorial suggests changing the SSH port, it's a well debated topic but honestly there's no need to, in fact many suggest not to.
As long as you disable root login and make use of a decent (I mean a very decent, non common word/s password) or SSH key's for your other users then you should be fine.
@lowendguy7 start with iptables......
Yeah, throw iptables at a Linux newbie! The pain cannot start early enough...
@Amitz what do you recommend?
Installing CSF, for example. That gives him at least some kind of GUI and a .conf file that he can edit to get some basic firewall protection in place. iptables is a nightmare for most starters.
@Amitz good recommendation
Well as I said above Im running solely from the command prompt at the moment. I like doing things this way actually makes me feel like a pro
CSF has a config file that describes what every option does and is very easy to edit/configure
Fully understood! Still iptables can take you from 'feeling like a pro' to 'I want to kill myself' within seconds... ;-)
You can use VNC Viewer which does not use java. RealVNC work on Windows/Linux/etc OS.
Ok so I installed it but not changed any settings yet. I did 'iptables-save' reading that apparently that chekcs if it's running but i can make no sense of the output so that doesnt help me.
Here is the output: https://gist.github.com/anonymous/98c5e42acea87e7ab397
Is it running then or not?
Also do I have to change any of the config options? or just leave the defaults. Also also does this program run on its own every time I boot up the server?
And now I have that installed do I still need to do the other stuff above such as making another user and changing the password?
Change your console font color to Green. That's what pro's in films do. /s
As previously mentioned, Installing CSF will help you.
what do you get for iptables -L -n
https://gist.github.com/anonymous/e64eb3f822fd77f97e96
hmm you didn't manage to save 'em
what do you get fr cat /etc/sysconfig/iptables
better for you to pm me for further assistance
I successfully managed to send over a test file earlier using pscp. I took a break then when I came back later and tried to send another file it won't work any more. I keep getting the message: Network error: network is unreachable.
Any idea what might have happened in the interim to cause it to stop working? Im still connected in the terminal and have functionality.
iptables running? could be blocking sshd
but why would it have worked earlier? i didnt change anything from when it worked an hour previous.
not quite sure, did you do anything? perhaps restarted something?
No.
is networking okay now? dacentec could have restarted or something too.
hey, settled?
edit.
EDIT: Never mind figured it out
. I was using ":" in the ip address instead of "."
github file 404 error
could be dacentec network, not sure tho
vnc in okay?
If you mean did I manage to transfer the files yes
Is there a way to reduce lag between my local machine and the server or is the only way to buy one nearer to me? Because there pause is a bit of a nuisance whenever I type.
you mean with vnc or ssh? vnc does have a lag but it's not too annoying, ssh wouldn't. probably the network
while we are on the subject, just like to clarify distance do not affect much since networks in North America and Europe run with optical fiber, more importantly, peer provider networks should work with optimum traffic volume.
only networks that still utilize copper cable connectivity ie Asia, will be affected by distance
