Re: [CentOS] Internet connection sharing? (OT)
Thank you very much for your reply.I am familiar with internet connection sharing on MS Windows as I have a third XP client on the same net connected to the internet.I tried as the following on my centos: #route add -net default gw 172.18.209.1 Where this is the secondary ip address of the MS Windows host.But the centos cannot see the internet. Can you please let me know why? Can you provide the IP details of this third XP client? If memory serves, the ICS feature of Windows is hardcoded to use 192.168.0.0/24 as the private range. Further, there's no way to share the Internet connection to other subnets. What happens if you configure the CentOS host as a DHCP client?

Re: [CentOS] Internet connection sharing?
And I know of a major incident, the vector and targets being all Windows systems. Sorry, I literally can't speak about how I know or more details I've been removing java from the computers I service. It's not used much if at all, and it's a vector. On one workstation I monitor, the java uninstaller removed java but left behind the java program's directories. The AV still finds malicious scripts being placed in the java folder after visiting infectious websites. Placed there by an updated version of IE8. Google Chrome , or even Firefox are the way to go for visiting those websites that no one admits to visiting... ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
