We have two internet lines with two different ISPs therefore we have two eths, eth5 and eth9. I'm showing that eth9 is offline and when I try to bring it up, I get a "RTNETLINK answers: File exists" error.
I'm showing eth9 is up so I thought it's the modem that has the problem and I contacted the ISP company, they advised me to connect a laptop directly to the modem and see if I can connect to the internet which I could so it is not the modem. Firewall is not connected to the modem and looks like there is a problem with the eth9. I ran the following ifconfig commands and everything looks OK to me.
Linux firewall.domain.com 2.6.18-194.8.1.v5PAE #1 SMP Thu Jul 15 02:01:47 EDT 2010 i686 i686 i386 GNU/Linux
Can you please help me find out what the problem is?
Thanks in advance
