Sysctl problem

Hi,

on my Redhat 7.3 I have following entries in /etc/sysctl.conf:

net.ipv4.conf.ppp0.log_martians = 1
net.ipv4.conf.ppp0.accept_redirects = 0
net.ipv4.conf.ppp0.accept_source_route = 0

But after reboot the values are not set.


So I tried in rc.local:

sysctl -w net.ipv4.conf.ppp0.log_martians=1
sysctl -w net.ipv4.conf.ppp0.accept_redirects=0
sysctl -w net.ipv4.conf.ppp0.accept_source_route=0

But still the values are not set.
What am I missing?

Cheers

Walter

When you had set these was ppp0 already up? If not you should
got an error like:

sysctl -w net.ipv4.conf.ppp0.log_martians=1
error: 'net.ipv4.conf.ppp0.log_martians' is an unknown key

You could either configure *all* interfaces by
net.ipv4.conf.all.log_martians = 1
net.ipv4.conf.all.accept_redirects = 0
net.ipv4.conf.all.accept_source_route = 0

or put the above "sysctl -w" stuff for the ppp0 into the
/etc/ppp/ip-up.local script. The latter might be the better
solution.

error: 'net.ipv4.conf.ppp0.log_martians' is an unknown key

You could either configure *all* interfaces by
net.ipv4.conf.default.log_martians = 1
net.ipv4.conf.default.accept_redirects = 0
net.ipv4.conf.default.accept_source_route = 0

or put the above "sysctl -w" stuff for the ppp0 into the
/etc/ppp/ip-up.local script. The latter might be the better
