Guess not.. Let me look into this  step by step in detail on our side. I'll get back to you guys .

root@pc62:/usr/local/etc/emulab/rc# sudo sysctl -w net.ipv4.icmp_ipod_host=0x80a38f0a
net.ipv4.icmp_ipod_host = 0x80a38f0a
root@pc62:/usr/local/etc/emulab/rc# sudo sysctl -w net.ipv4.icmp_ipod_mask=0xffffffff
net.ipv4.icmp_ipod_mask = 0xffffffff
root@pc62:/usr/local/etc/emulab/rc# sudo sysctl -a | grep ipod
error: permission denied on key 'net.ipv4.route.flush'
error: permission denied on key 'net.ipv6.route.flush'
net.ipv4.icmp_ipod_version = 2
net.ipv4.icmp_ipod_enabled = 1
net.ipv4.icmp_ipod_host = -2136764662
net.ipv4.icmp_ipod_mask = -1
net.ipv4.icmp_ipod_key = fca4b3328257112088c3188fb66be36d

I used the 2.6.25 patch from Utah on a 2.6.27 kernel , Do you think it  
must have been the patch ?
    

David asked me to look into this.  I've successfully used the patch on
a 2.6.27.8 kernel, so I'm not sure why it's not working for you on
2.6.27.

Try setting the ipod_host and ipod_mask values directly:

sudo sysctl -w net.ipv4.icmp_ipod_host=0x80a38f0a
sudo sysctl -w net.ipv4.icmp_ipod_mask=0xffffffff

Then do 'sudo sysctl -a | grep ipod' and see if the change worked.
