How to enable SSH access on a new installed centos 6.3 server
I installed a new centos server locates on DMZ zone. When I tried to putty it from my desktop on LAN zone, it gives me "Network Error: connection refused" . I am guessing that i need do some configurations for the putty protocol although I have already set up network card configurations. Please advise, thank you. I use IP address on the putty, so there is no dns problem involved here.
thank you for update, bad thing is my firewall is a Cisco PIX 515E, it doesn't have a GUI setup on my company. I used sonicwall for many years and get accustomed to GUI interface.
If i want to enable GUI on this device, how could I do it? I googled on line and says there is an application called asdm can manage cisco firewall. Do I need install this program or just use the IE to manage it.
Yes, I do want to access internet from this CentOS machine. It looks like the firewall blocked the outgoing traffics. Since I can log onto the intranet without any problem.
Do you mean going to Internet (http) from CentOS?
If so, you must open port 80 on the firewall between the DMZ and the outside world for the CentOS host.
If you want to ping Internet hosts you must allow ICMP request/reply packets on that firewall.
But I can't go to internet, even after I disabled the inbuilt firewall.
Do I need check the policies on my cisco PIX 505E firewall?
I tried to ping google.com, it doesn't give me responds.
