Hi, I installed CentOS 3.3 and kept the machine up2date. I installed poptop and the newest ppp-cvs version ( ppp-2.4.3-0.cvs_20040527.6) We are running a ssh + ppp tunnel for our internet tunnel/tunnel to our NOC. After the upgrade we see these error messages while starting the tunnel: Jan 24 15:00:40 natgw modprobe: modprobe: Can't locate module ppp-compress-26 Jan 24 15:00:40 natgw modprobe: modprobe: Can't locate module ppp-compress-24 Jan 24 15:00:41 natgw modprobe: modprobe: Can't locate module ppp-compress-21 Jan 24 15:00:41 natgw modprobe: modprobe: Can't locate module ppp-compress-26 Jan 24 15:00:41 natgw modprobe: modprobe: Can't locate module ppp-compress-24 Jan 24 15:00:41 natgw modprobe: modprobe: Can't locate module ppp-compress-26 Jan 24 15:00:41 natgw modprobe: modprobe: Can't locate module ppp-compress-24 Jan 24 15:00:42 natgw modprobe: modprobe: Can't locate module ppp-compress-21 I googled and found that we have to add some aliases,like so: /etc/modules.conf: alias ppp-compress-21 bsd_comp #alias ppp-compress-21 off alias ppp-compress-24 ppp_deflate alias ppp-compress-26 ppp_deflate But still after a pppd restart the problem persists (ppp failes and reconnects) ..am I a missing a package or do I have to do another thing to enable these modules? I can find the .c files: [root at natgw etc]# locate bsd_comp /usr/src/linux-2.4.21-27.0.2.EL/drivers/net/bsd_comp.c but not the modules (.o files) Thanks for your help. -- Kind Regards,
