Hello.

I am try use kernel (almost casually) with out "hidden patch".
I was surprised - but real-server - normally works!

Now hidden-patch really it is not necessary?


Kernel:
ftp://ftp.suse.com:/pub/people/mantel/next/linux-2.4.19.SuSE-25.tar.bz2

1.

# echo 1 > /proc/sys/net/ipv4/conf/dummy0/hidden
bash: /proc/sys/net/ipv4/conf/dummy0/hidden: No such file or directory

diamond:/var/log # echo 1 > /proc/sys/net/ipv4/conf/all/hidden
bash: /proc/sys/net/ipv4/conf/all/hidden: No such file or directory



2. IPVS config:

# ipvsadm -L -n
IP Virtual Server version 1.0.5 (size=32768)
Prot LocalAddress:Port Scheduler Flags

3. REAL server config:

#cat real-server.sh
#!/bin/sh
        echo 1 > /proc/sys/net/ipv4/ip_forward
        ifconfig tunl0 0.0.0.0 up
        ifconfig dummy0 0.0.0.0 up
        echo 1 > /proc/sys/net/ipv4/conf/all/hidden
        echo 1 > /proc/sys/net/ipv4/conf/dummy0/hidden
        ifconfig dummy0:0 192.168.15.68 up
        ifconfig dummy0:1 192.168.15.70 up


# ifconfig
