must be something stupid...

[root@fe4026 fea]# /sbin/ifconfig dummy0 up
[root@fe4026 fea]# echo 1 > /proc/sys/net/ipv4/conf/all/hidden
[root@fe4026 fea]# echo 1 > /proc/sys/net/ipv4/conf/dummy0/hidden
bash: /proc/sys/net/ipv4/conf/dummy0/hidden: No such file or directory
[root@fe4026 fea]# cd /proc/sys/net/ipv4/conf
[root@fe4026 conf]# ls
all  default  eth0  eth1  lo

could someone explain why dummy0 doesn't get created in
/proc/sys/net/ipv4/conf/. ?  I don't have much experience with alias
interfaces and ifconfig... ( do I have to create them? )
