Hi All,
I have 2 NICS in this system. CentOS 6.4
eth0 is the virtual IP from PFSense mapping connected to the router, works fine.
eth1 is a second NIC that I have assigned a private IP to and connected it to a switch on the private network. I have many other private devices, so I know this setup works.
When I connect the cable to the switch and bring up eth1 the system basically stops taking requests. I can no longer SSH in, Websites stop responding, etc. If I walk over to the server and take down eth1, everything works fine.
Here is eth0: DEVICE=eth0 HWADDR=00:1b:21:cd:80:bf TYPE=Ethernet UUID=68a95912-3915-4b1a-9080-eb2017330153 ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=none IPADDR=192.168.1.27 NETMASK=255.255.255.0 DNS2=8.8.4.4 GATEWAY=192.168.1.1 DNS1=8.8.8.8 IPV6INIT=no USERCTL=no
Here is eth1: DEVICE=eth1 HWADDR=00:0a:cd:17:07:7e TYPE=Ethernet UUID=b3851363-ae9e-4066-8993-caed07b9945b ONBOOT=no NM_CONTROLLED=yes BOOTPROTO=none IPADDR=10.0.254.11 NETMASK=255.255.255.0 GATEWAY=10.0.254.1 DNS1=8.8.8.8 DNS2=8.8.4.4 IPV6INIT=no USERCTL=no
I have never experienced this before.
Also, when I check system-config-network-tui, some .bak, which I made, but deleted the files from the file system when I was trying a few things. But how do I get rid of them?
I attached a screenshot
