Hello,
Currently, I manage gentoo system that have a variety of 10 and 100 MB/s ethernet cards. I use lshw to distinguish the max ethernet port speed: For example: network:0 DISABLED description: Ethernet interface product: RTL-8139/8139C/8139C+ vendor: Realtek Semiconductor Co., Ltd. physical id: 9 bus info: p...@0000:02:09.0 logical name: eth1 version: 10 serial: 00:48:54:62:64:fd size: 10MB/s capacity: 100MB/s width: 32 bits clock: 33MHz capabilities: pm bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=8139too driverversion=0.9.28 duplex=half latency=32 link=no maxlatency=64 mingnt=32 module=8139too multicast=yes port=MII speed=10MB/s *-storage UNCLAIMED description: Mass storage controller product: PCI0680 Ultra ATA-133 Host Controller vendor: Silicon Image, Inc. physical id: a bus info: p...@0000:02:0a.0 version: 02 width: 32 bits clock: 33MHz capabilities: storage pm bus_master cap_list configuration: latency=32 *-network:1 description: Ethernet interface product: 3c450 HomePNA [Tornado] vendor: 3Com Corporation physical id: b bus info: p...@0000:02:0b.0 logical name: eth0 version: 30 serial: 00:50:da:61:31:1c size: 100MB/s capacity: 100MB/s width: 32 bits clock: 33MHz capabilities: pm bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=3c59x duplex=full ip=192.168.2.17 latency=32 link=yes maxlatency=10 mingnt=10 module=3c59x multicast=yes port=MII speed=100MB/s Is this reliable? What if a 10/100 card is plugged into a 10MB/s hub? Is there other software to discern the hardware capability and test actual throughput? How comfortable are you with the results you get? (reliable?) curiously, James
