Hello List, When I do: # ifconfig I see the following interfaces listed: tx0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 192.168.254.3 netmask 0xffffff00 broadcast 192.168.254.255 inet6 fe80::2e0:29ff:fe11:ff8a%tx0 prefixlen 64 scopeid 0x1 ether 00:e0:29:11:ff:8a media: Ethernet autoselect (100baseTX <full-duplex>) status: active lp0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500 sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 552 faith0: flags=8002<BROADCAST,MULTICAST> mtu 1500 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x5 inet 127.0.0.1 netmask 0xff000000 ppp0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500 I know tx0 is my one and only nic, we can keep it. I assume lp0 is the parallel port, don't need it, don't plan to do any printing from this machine. I assume lo0 is the loopback interface, that's cool. I know I don't need a PPP or SLIP interface, I have a LAN connection to the Internet. I've grepped LINT and GENERIC with no joy for the definitions, I've Googled with no joy so far, there are no man pages for these devices, where can I find out what they are? I realize the only ones actually running are tx0 and lo0, but wouldn't it be OK to remove the ones I'll never need? Can I get rid of some of these guys? How? Thanks, Charles
