I'm using Centos4.1 kernel 2.6.9-11.106 and I'm trying to install a pptpd, but have run into a snag. the following is where I'm stuck. [root at centosserver noarch]# rpm --install kernel_ppp_mppe-0.0.5-2dkms.noarch.rpm Creating symlink /var/lib/dkms/kernel_ppp_mppe/0.0.5/source -> /usr/src/kernel_ppp_mppe-0.0.5 DKMS: add Completed. Module build for the currently running kernel was skipped since the kernel source for this kernel does not seem to be installed. So I then Try to install kernel-sourcecode from yum which will then download but say bad key, or it will hang. I tested yum on other packages and it works fine. I also downloaded from rpm.pbone.net and got: rpm -ivh kernel-sourcecode-2.6.9-11.EL.noarch.rpm error: kernel-sourcecode-2.6.9-11.EL.noarch.rpm: V3 DSA signature: BAD, key ID 443e1821 error: kernel-sourcecode-2.6.9-11.EL.noarch.rpm cannot be installed. Anyone know away around this, I'm also willing to recompile the kernel but I'm not sure if that will help. I have been following the following link for instructions on installing mppe http://pptpclient.sourceforge.net/howto-fedora-core-3.phtml Thanks, Kevin
