I am wondering if anyone knows what i am doing wrong. This has been bothering me for months. I have a Fedora Core 2 machine in another city that i monitor remotely. It has 2 NICS. One of them is connected to a LAN and has an IP address always. I use this to ssh into the box on a daily basis. The other card is in promiscuous mode with no IP address and sniffs traffic from a DMZ. (if you haven't guessed yet its a snort box). Every once and a while there comes a need for me to give the card on the DMZ an IP address temporarily. This is what i do: 1) I SSH into to the LAN CARD, become root. 2) I then use system-config-network-gui though the ssh connection to get a nice gui from the remote machine. 3) There is no DHCP server on the DMZ so i give it a static address on the same subnet, set subnet mask to 255.255.255.0 and default gateway to the correct default gateway. 4) I then apply changes and activate the card. At this point it kicks me out. It makes sense on some level that it would kick me out because the applet is restarting the network service. My problem however is that i can no longer get back onto my machine. on either card!!! I also know why i wouldn't be able to get into the DMZ card since I'm not on the DMZ, but why does my LAN card stop accepting ping or anything else. Is there something i am doing wrong? Is there a better more effective way accomplish what i am doing? Thanks for all your help, Seth P.S I know the temp static IP, default gateway and subnet mask that i am giving the card are fine because the same numbers work on a windows machine.
