De cualquier manera, alguien se est'a robando tu IP, aunque sea por unos segundos. Los numerillos que reportas son la direcci'on MAC de las tarjetas de red, una de ellas es la tuya. Bastar'ia que teclearas: ifconfig para ver tus interfaces y sus direcciones MAC. Seguro una de ellas es la que reportas. As'i que alguien est'a usando una direcci'on IP fija, de manera que, cuando prende su computadora, le roba la IP a la tuya. Luego se apaga dicha m'aquina y t'u vuelves a la normalidad. Tendr'ias que reportar este hecho con tu proveedor de servicio de Internet. Ellos podr'ian ver quien est'a usando la direcci'on fija y pedirle que ya no lo haga. > > > > This isn't my computer, and I'm 40 minutes away from it, so if this > > question needs information it might be slow in coming. > > > > -- > > Mike Burns > > "Gentlemen, you can't fight here -- this is the War Room!" - Dr. Strangelove > > _______________________________________________ > > freebsd-questions@freebsd.org mailing list > > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" > > > > - ______ _ > * / /###\ / \ __ > /\ /\ * / ./#### \ * \__|_/ | | > / \/ \ | b#####| * _ | __ | | __ > = .. \____ \ \_\#####/ / \| / \ | | /\_\/ > = \_| * \___\###/ * \_/\_/\__/\__\/_/\__/ > = \______/ _ > | | > - ______ _ * / /###\ / \ __ /\ /\ * / ./#### \ * \__|_/ | | / \/ \ | b#####| * _ | __ | | __ = .. \____ \ \_\#####/ / \| / \ | | /\_\/ = \_| * \___\###/ * \_/\_/\__/\__\/_/\__/ = \______/ _ | |
