Well, if you don't have a switch or router between your linux box and that PC you are looking for, you can use the following methods. 1. ping ip_addr, then arp will show you MAC-IP pairs that was discovered. 2. there's a good utility called arpwatch - this is a daemon which monitors network activity in your segment and mails you (root@localhost) all discovered ip and mac addresses. It also informs you if the mac changes, it is very useful if you're sysadmin and try to supervise your network. -- |< () http://kir.sever.net [EMAIL PROTECTED] [EMAIL PROTECTED] ICQ 7551596 () |_ Microsoft SELLS you Windows, Linux GIVES you the whole house! _______________________________________________ techtalk mailing list [EMAIL PROTECTED] http://www.linux.org.uk/mailman/listinfo/techtalk
