Package: linux-2.6
Version: 3.0.0-3
Severity: normal
Dear Maintainer,
I have a vpn gateway that periodically sends icmp redirects to the hosts of my
network (when renegociating tunnels), I configured hosts not to accepts
reidrects by uncommenting the default directive found in sysctl.conf:
net.ipv4.conf.all.accept_redirects = 0
after reboot here is the config i get in /proc/sys:
cat /proc/sys/net/ipv4/conf/*/accept_redirects
0
1
1
1
1
If i try to echo the value in the proc filesystem, It's no better:
root@elronde:/home/alxgomzecho 0 /proc/sys/net/ipv4/conf/all/accept_redirects
root@elronde:/home/alxgomz# cat /proc/sys/net/ipv4/conf/*/accept_redirects
0
1
1
1
1
Where I expected this to put all interfaces to zero.
the entry ./default/accept_redirects seems to work as expected.
I have seen the same behaviour for other proc entries such as send_redirects
and notices the bug #630650 that is maybe related.
