Again, "ifconfig" shows interfaces that are up. "ifconfig -a" shows all known interfaces, up or down. Example, from my laptop (note the tagged line in the second command): [root@golem4 ~]# ifconfig | grep flags lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 p4p1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 virbr0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 [root@golem4 ~]# ifconfig -a | grep flags lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 p4p1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 virbr0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 virbr0-nic: flags=4098<BROADCAST,MULTICAST> mtu 1500 <<<<<<---------- wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@xxxxxxxxxxxxxx - - AIM/Skype: therps2 ICQ: 226437340 Yahoo: origrps2 - - - - Grabel's Law: 2 is not equal to 3--not even for large values of 2. - ---------------------------------------------------------------------- _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
