HI folks. I am developing a protocol and I need to bind to an IP address that is not configured to my machine. The problem is with bind(). The sysctl system call seamed to overcome the problem of bind if you set the proc/sys/net/ipv4/ip_nonlocal_bind flag. Although I tryed to set the flag either from command line by writing sysctl -w net.ipv4.ip_nonlocal_bind=1, or echo 1>proc/sys/net/ipv4/ip_nonlocal_bind, or programmatically by using the command sysctl(), or by seting its value from the /etc/sysctl.conf file, bind still generates an error. Does anybody have any idea of why this is happening? Is there any other way to bind to a non local IP address?

PS. In the kernel configuration the sysctl support(CONFIG_SYSCTL) is enabled together with the /proc file system support (CONFIG_PROC_FS).
