Does any one know the (technical) difference in using sysctl verses echoing values in to the appropriate areas in side of the /proc file system? Which is the more current (expected in the future) practice? Any ideas and / or thoughts on this matter would be greatly appreciated. Consider this very simple and common example: sysctl -w net.ipv4.ip_forward=1 verses echo "1" > /proc/sys/net/ipv4/ip_forward Grant. . . . ^ permalink raw reply [flat|nested] 2+ messages in thread

Really calling sysctl to do it is just another step when using echo would do it anyway. On the other hand, if sysctl can be used to log anything so you can possibly reverse any changes may be an idea, but the only things I have ever changed (that I can think of) in /proc are ip_forward and tcp_conntrack_max, which have been with an echo and then editing /etc/sysctl.conf to match.
