[CentOS] default gateway outside of the LAN

Hello all, We have a somewhat unique setup whereby our default router is outside of the local network. Let us say our network is 192.168.10.0/255.255.255.0 So we have a route-eth0 file that looks something like this: 10.1.1.1 via 192.168.10.1 dev eth0 default 10.1.1.1 dev eth0 The last

Hello again, Looks like the functions I need - at least some of them - are defined in videobuf-vmalloc.h I still have no idea where to find them - i.e., what to include/install to make them resolve. Boris. On Mon, Jul 23, 2012 at 5:48 PM, Boris Epstein borepst...@gmail.com wrote: Hello all

[CentOS] XFS-in-a-file

Hello listmates, Has anybody attempted to run an XFS in a file mounted via -o loop? The file size is about 20 TB and it resides in a larger XFS filesystem residing on a disk. That filesystem's size is about 25 TB. What sort of degradation should one expect under that sort of scenario? The reason

[CentOS] working dhcpd.conf with routes

Hello listmates, I am running DHCPD for IPv4 on a Centos 5 machine. I am wondering if anyone has got a functional dhcpd.conf configuration serving static routes to Linux, Mac OS X and Windows clients. I tried a couple of variations of static-routes options - but have yet to create something that
