When trying ifconfig -a no tun# devices are listed. Creating one with ifconfig tun0 create fails. When trying kldload /modules/if_tun.ko kernel complains that the device or module is already present. (Which it should be of course when compiled in the config phase.) >How-To-Repeat: # kldstat Should show no if_tun.ko. # ifconfig -a Should show no tun0 etc. # ifconfig tun0 create Fails complaining about SIOCIFCREATE and wrong argument. # kldload /modules/if_tun.ko Complaint about the module already being present. >Fix: None known yet. The symptoms make me suspect the call parameters to ioctl SIOCIFCREATE might have changed in the kernel, but the user-land has not kept up. - This guess might be totally in the woods. It is just the first potential explanation that occured to me. >Release-Note: >Audit-Trail: >Unformatted:
