<DIV>Iam using Redhat Linux 7.2 My kernal version is 2.4.18-3 Iam new to linux.Iam trying to rum SCPS gateway in our testbed.For that I have to complie Linux 2.4.X Before compiling the SCPS code, the underlying kernel support number must be enabled. The following supporting software must be obtained and installed from other sources if not already present on the system. tun/tap modules from <A href="http://vtun.sourceforge.net/tun" target=_blank>http://vtun.sourceforge.net/tun</A> brctl from <A href="http://bridge.sourceforge.net/" target=_blank>http://bridge.sourceforge.net</A> In order to run the SCPS gateway under the Linux operation system via the TAP method, the following kernel configuration options must be enabled before configuring the SCPS software. UNDER NETWORKING OPTIONS 802.1d Ethernet Bridging UNDER NETWORKING DEVICE Universal TUN/TAP device driver support So I have my BRCTL working.I have also downloaded the tun/tap driver. I would like to configure my kernal to enable ethernet bridging and universal TUN/TAP device driver support. The sticking point is when I try to run make xconfig, config, or menuconfig (I get the 'no target' error). Also, the directory 'usr/src/linux' doesn't exist, I know it's supposed to be in the redhat directory, but I can't 'make' anything in there either. When I type in make xconfig I get the following error message. [root@rx redhat]# make xconfig make: *** No rule to make target `xconfig'. Stop. What should I do further. Please help me out. </DIV> <DIV> </DIV>
