I can understand mask for an ip address but can not understand mask value for an interface. For example what can be the mask for eth0? 36 char iniface[IFNAMSIZ], outiface[IFNAMSIZ]; 37 unsigned char iniface_mask[IFNAMSIZ], outiface_mask[IFNAMSIZ]; Can anyone write me some about "iniface_mask[IFNAMSIZ]" ? thanks, Ozgur AKAN --------------020001030205090506000906 Content-Type: text/html; charset=ISO-8859-9 Content-Transfer-Encoding: 8bit Hi,

36         char iniface[IFNAMSIZ], outiface[IFNAMSIZ];
37         unsigned char iniface_mask[IFNAMSIZ], outiface_mask[IFNAMSIZ];

Can anyone write me some about "iniface_mask[IFNAMSIZ]" ?

thanks,
