i installed guard dog on my server, luckily i was able to use it. coz i thought i messed up my entire system. I wasnt the one who configured the firewall before and also i dont know how does this server share the internet. All i wanted to do is to block some internet sites, and it did. But a whole lot of issues now arises on this newbie again...
1. Using guard dog program is a little bit easy, considering you just have to check the boxes that u want to block or not, u just have to specify to which zone you want to apply the protocol. But i checked all the options in the Interactive session group and made sure that it all options are allowed and I cant still connect remotely from another station to my server...I use SecureCRT for SSH Secure shell connections, and operation always times out? what did i do wrong? pls help! i need to connect to it, using SSH!!
2. In case i wanted to uninstall and revert to my previous firewall settings how do i do it? it says on the manual of guard dog that it configures the /etc/rc.firewall so i backed it up before using guarddog. but the question...if i revert the old rc.firewall, how do i restart the firewall? and would it work? because on the first time that i installed guarddog, and i configured it and added a zone named LAN with specific IP addresses for that zone that is (192.168.0.0/24), i wasnt able to check all the allowed protocols, and so i PANICKED...because there were no internet on all stations. But i calmed down and tried the program again, and it worked.
How can i bring back my old firewall configuration and is this like samba that you can restart after configuring the rc.firewall??? help pls!
3. Is there uninstall method on Linux? what if i wanted to remove installed RPM's on my box, how do i do it?
4. How does Linux share the Internet resources to a certain domain(it is a samba primary domain controller on another linux box). the setup is like this, i configured guarddog on server1, and it also connected to the network with another linux server, server2 which is the Primary Domain Controller (PDC) and all are connected to the network.
