ibby Reviewed by ibby on 27th Mar 2012. Secure a server? How much would a general "Securing a server" going to cost? OR is it fairly simple with just afew lines via ssh? The server it self, users won't be able to login via ssh btw. Let me know please, it might come in handy for some users here. Rating: 5

He mainly does windows servers he is not a linux techy.

As for GeeZus this is something you can easily do yourself.

Learn deny and allow in iptables since you are using ubuntu.

First edit /etc/ssh/sshd_config to listen only on your server ip address

deny all traffic

iptables -A INPUT -p tcp -s 0/0 --sport 513:65535 -d ser.ver.ip.here --dport 22 -m state --state NEW,ESTABLISHED -j DROP

Accept from only your ip

iptables -A INPUT -s ! you.r.i.p -p tcp -m --dport 22 -j ACCEPT

edit: XSLTel pulled out a one liner well what he said should work.

As James said, NEC deals with Windows mainly.
